Education in International Development - Essay Example till, it has been noted that the problem is not inherently linked to the political process and could be linked to disconnect between the citizens’ needs and the country’s policies. Gewald et al (2012: p29) emphasize the critical link between political participation and education, especially noting that education is essential to the social, economic, and political development of Zambia. Zambia’s Ministry of Education has since the early 90s been determined enhance access and quality of education in accordance to the societies needs (Sardanis, 2014: p21). This paper will seek to discuss the effects of underdevelopment on the provision of education in Zambia, while also evaluating the impact of policies, practices, and projects on schooling in Zambia. First, an overview of Zambia’s current economic development and political situation will be given. Zambia’s economy is heavily reliant on the mining industry, specifically copper mining. However, the costs of production continues to rise as copper reserves are depleted, while income is unstable due to copper prices on the world market, which has been identified as a reason why Zambia should diversify its economic base (Baldini & IMF, 2012: p35). The agricultural industry is poorly developed, while major investments both public and foreign in the manufacturing industry only took place following the country’s independence from Britain. Involvement of the state in almost every economic aspect has led to a highly bureaucratic and centralized economic structure. In real terms, economic growth in 2013 in Zambia declined by 6.5%, particularly because of a fall in output of cotton and maize that makes up most of the country’s economic output (Baldini & IMF, 2012: p35). Largely, real GDP growth is driven by the public, transportation, construction, communications, min ing, and manufacturing sector. Copper contributes to at least 70% of Zambia’s export earnings, although non-traditional exports like agriculture

Personal Philosophy of Classroom Management Essay Example for Free

Personal Philosophy of Classroom Management Essay Classroom Management is an essential element in implementing a successful learning environment for students. A teacher who implements a classroom management plan will control student’s misbehavior so that all students will be focused on the lessons being taught in the classroom. Below is an annotated list of points that I believe in concerning my view of classroom management. 1. How teacher should act: * Enthusiastic- A teacher should show enthusiasm when she is teaching the lessons. The teacher needs to show that she is excited about teaching the lessons so that the students will stay interested in listening and understanding the subject area content. * Respectful- The teacher should treat students with respect and also demand respect. She should never use fowl language, inappropriate behavior, share too much personal information or act in ways that are not ethical. * Role Model- A teacher should act as a role model to her students. The teacher should not do anything that would jeopardize her career as a teacher that would make her students look down upon her. She also must live a life that students look up to so they will remember that teacher forever. * Patiently- A teacher must exhibit patience in class. Every student learns at different paces and at different levels. A teacher must be willing to be patient if the students are not grasping the information. She should explain the information to the students until they finally understand the lesson 2. How students are expected to behave: * Respectful- Students are to be respectful towards the teacher and to each other. Students should show respect to the teacher by not talking when the teacher is instructing the class. The students should show respect to each other by not hitting each other, making fun of another, or taking one’s personal belongings. * On Task-Students should stay on task in class. Students should be focused on the teacher’s lessons and instructions. They should not be wandering off getting off task. If the students are off task, they will not understand the lessons or remember what happened in class. Also the teacher will have to go back and teach the lesson again which can cause the teacher to be off target teaching the curriculum and it will result in student’s receiving poor test scores. * Appropriately Well Behaved- Students should be well behaved in class. It is important for students to understand the importance of good behavior. If students are well behaved in the classroom, the teacher can spend more time instructing the students than time spent on behavioral issues. In a well behaved classroom, students are able to learn effectively. * Academically Prepared- Students are to come to school academically prepared. The students should complete their homework assignment each day in order to make sure they understand the subjects that are being taught. They should always come prepared to listen to the subject matter, offer their opinions, and ask god questions in class. 3. What the classroom might look and feel like: * Engaging- The classroom should look and feel engaging to the student. In the classroom, the teacher can arrange the classroom that promotes student interaction and group collaboration. Students should be seated in a circle or horseshoe shape that maximizes the amount of eye contact students can have with each other. * Clean and Organized Classroom- A teacher’s classroom should be clean and organized. The school supplies should be neatly organized and in a safe place where students can safely access the supplies. * Filled with student’s work- The classroom should be filled with student’s work on projects. The students will feel comfortable and engaged if what they are learning in class will be showcased in the classroom. The student can look around the room and be reminded to always do their best on their assignments. This also sends a message to students that their work and learning is important. * Student Centered The classroom should be focused on the students. In the student centered classroom, you will find workstations that promote group activities such as puzzles or brainteasers that promote student collaboration. 4. How the teacher helps students conduct themselves properly: * Demonstrating the Rules- The teacher should teach, review, and practice rules form beginning of school till the end of school. The teacher should also let students demonstrate good behaviors and bad behaviors so that students will understand how to follow the rules and to have good behavior in class. * Reinforce positive behavior with Incentives- A teacher can help students conduct themselves properly by providing incentives through positive behavior. A student who exhibits positive behavior weekly will pick a price out of the treasure chest. This will result in students with bad behavior to act better if they see students winning cool prizes. * Student and Parent Contracts- To ensure students are behaving properly, student and parent contracts are sent home for parents and students to sign. This contract outlines what is expected from the student’s behavior, academics, and the parent’s commitment in the child’s education. This will be very helpful in helping the students have good behavior in class. * Character Education Mini Lessons tied to Curriculum- Teachers can tie in the classroom rules and good behavioral skills as mini-lessons. Before teaching the lessons, the teacher can discuss how to treat others, how to walk quietly in the halls, and do not talk while others are talking. By having these mini lessons on how students should behave will remind them of how to have good behavior in class. 5. What the teacher should do about misbehavior: * Cues- Teachers uses a cue or a simple verbal reprimand to redirect a student’s focus which eliminates the inappropriate behavior. A teacher can also praise the efforts of students with good behavior which can reduce the misbehavior among the other students. * Consequences such as loss of recess- If a student keeps misbehaving, the teacher can use the consequence of loss recess. The majority of students like to go to recess. If the student knows their punishment by loss of recess due to their misbehavior, their behavior will improve. * Private conference with student- If the student still misbehaves, the teacher will need to talk with the student. The teacher will inform the student that his or her misbehavior will not be tolerated in class and his or her parents will be contacted if the misbehavior continues. * Contact parent- A teacher should contact the parents if the student keeps misbehaving in class. If the teacher lets the parents know how their child behaves in class, then the parents can also talk to the child and discipline them at home. 6. How students should be taught and what is expected of them: * Post rules in the classroom- Teachers can post rules in the classroom so that students can be reminded each day of how to properly behave in class. Also the teacher can give quizzes to students about the poster rules throughout the year. * Clear articulation and communication in the syllabus- Teachers should communicate clearly about what is expected of student’s assignments and their behavior in class. For example, informing students to always do their best on their work or their handwriting must be neat on all of their assignments should be clearly communicated. Creating a syllabus will also inform students of when their assignments are due.

Efficient market hypothesis

Efficient market hypothesis Introduction: From the last several decades the efficiency of stock market has been the sole purpose of research studies. As a result, several theories have been introduced and implemented in relation to principally how the competition in the stock market will force the known information into the prices of securities. The knowledge of information on a variety of securities that are traded in the market is one of the major factors in influencing the movements of stock market. In the stock market, a securities price tends to move rise and fall depending mainly on the availability of the information. The stock prices in the efficient market correspond to available information and therefore register any rise or fall mainly when recent and unpredictable information is available. The up and down in the security prices largely depends upon the advantages and disadvantages associated with the available information and to what extent it will affect the companys performance which is represented by the secur ity. As it is very difficult to tell whether the information available is useful or not, in the same way it is quite impossible to make predictions about the trend of the stock market, such that whether there will be an upward or downward trend in the near future by using the available information. In the financial market it is not mandatory that all professionals related to market always possess the information about the securities and have skills to evaluate this information for their gain. The only thing the efficient market requires is that few individuals must have the information about securities and as a result of the information supplied by them, the whole market must be well informed and benefitted. Hence the available information plays an important role in determining the efficiency of the stock market. By focussing on the above idea, the concept of Efficient Market Hypothesis has been developed and became one of the most concentrated and debatable topic among professionals and people related to finance and stock market studies. RESEARCH AIM: The main aim of my research is to analyse the efficiency of stock market supported by the concept of Efficient Market Hypothesis. It also aims to depict the impact of the Efficient Market Hypothesis on security trading by reviewing the available literature. RESEARCH QUESTIONS: My research aims to answer the following questions: To what extent the available information, according to the concept of Efficient Market Theory, affects the security trading in stock market. What is insider trading and its impact on the efficiency of stock market. What are the various types of anomalies associated with the stock market and their effect on the stock market efficiency. LITERATURE REVIEW: In this part of my research paper I will re-examine the existing literature on the anomalies and the efficiency of the stock market. An efficient market is defined as a market where there are large numbers of rational, profit-maximizers actively competing, with each trying to predict future market values of individual securities, and where important current information is almost freely available to all participants. In an efficient market, competition among the many intelligent participants leads to a situation where, at any point in time, actual prices of individual securities already reflect the effects of information based both on events that have already occurred and on events which, as of now, the market expects to take place in the future. In other words, in an efficient market at any point in time the actual price of a individual securities already reflect the effects of information based both on events that have already occurred and on events which, as of now, the market expects to take place in the future. In other words, in an efficient market at any point in time the actual price of a security will be a good estimate of its intrinsic value.(Eugene F. Fama 1965) According to the Efficient Market Hypothesis, given by Fama, the ups and downs in the prices of securities in the financial market totally reflect known information at a specified period of time. In other words, Efficient Market Hypothesis states that the trading of securities by the individuals is always carried out purely based on the assumption that securities worth are always more or less than the price offer by market. Whereas, trading of securities trying to outperform the stock market will be luck instead of professional skills if current prices fully reflect all available information as well as stock markets are efficient. According to this hypothesis if new information is revealed about a firm it will be incorporated into the share price rapidly and rationally, with respect to the direction of the share price movement and the size of that movement. (Elearn -NetTel) . Efficiency is an unclear word in itself so for more clarification, in my dissertation, I will describe all ty pes of efficiencies: operational, allocation and pricing. I will also give full detail on levels of market efficiency : weak-form efficiency, semi-strong form efficiency and strong-form efficiency. According Random walk theory , there are no trends and format that are being followed by the prices of securities in stock market. There is another fact given by this theory which says that the prices of securities in the past can not be useful for future predictions and fluctuation in prices. The Efficient Market Hypothesis and anomalies related to the stock market developed by the researchers always contrasts with each other. The search for anomalies is effectively the search for systems or patterns that can be used to outperform passive and/or buy-and-hold strategies. (Invest Home). With the invention of any anomaly, there is always a kind of exploitation by the investors of the anomalies discovered in order to increase their profit. This practice make the anomaly disappear with the passage of time. There are so many internal and external factors of the entities that affects the operations of stock market and those factors are often known as Anomalies which plays an important role in over performing or under performing the operations of the stock market by taking into consideration the fact that these anomalies have good or bad effect on the prices of stocks and entities. There are different types of anomalies and some of the anomalies are discussed. Fundamental Anomalies: First type of anomaly is fundamental anomaly which basically depends upon the price of the stock and on the past performance of the entity due to which stock prices rises or fall. Several anomalies of these kinds exist related to the growth, present value and profitability of the companies concerned. Under fundamental anomaly, there exist a most historical and famous anomaly named Value investing and is regarded as the most appropriate strategy for investment purposes. These anomalies depend on the stock value and companys performance based on which the stock prices go up or down. A technique used is to divide the given index into high price and low price to book value stocks. The low price to book concept was developed by Eugene Fama and Keneth French favouring the hypothesis that lower risk is attached to value stocks whereas the stocks with growth are attached with higher risk. According to another anomaly named as low price to sales, stocks with low price to sales ratio perform b etter then high price to sales ratio. According to James P. O Shaughnesey, prices are the only strongest determinant of excessive return. There are several studies which advocates that stocks having low P/E ratio always perform better in the market as compared to stocks with high P/E ratios. In the same manner, the stocks with high dividend yield are better performers than stocks with low dividend yields. There are some other stocks named as neglected stock and are chosen by those with the contrarian strategy. A study was conducted by F.M DeBondtand Richard Thaler on 35 best and worst performer stocks between 1932 and 1977 in New York Stock Exchange and came out with the result that the performance of best performer stocks in the stock exchange falls whereas the stocks with bad performance in the past showed better results when compared to the results of the same stock in the past. Technical Anomalies: Another types of anomalies in which past prices and statistics are used to predict the prices of securities are known as technical anomalies. The techniques used in these types of anomalies include strategies related to support and resistance, moving averages and strength. Some researchers are against the method of technical analysis and say that the investors are hardly benefitted from these technical analysis techniques where as some researchers argue that there is enough evidence and facts that are sufficient to say that the technical analysis method is favourable for the investors. According to technical analysts, the selling of stocks is influenced by the resistance level whereas the buying is influenced at the support level. A signal to sell the stock is developed in case the support level is penetrated by the price whereas a signal to buy the stock is produced in case price penetrated the resistance level. According to the conclusion made by William Brock, Josef Lakonishok, an d Blake LeBaron, the outcomes are reliable with technical rules having forecasting power. But at the same time the cost related to transaction must be taken into account before implementing such concepts and strategies. Another conclusion given by them says that the stock returns generating is more complicated and different process as compared to the results obtained by conducting different studies and researches using various linear models. Calendar Anomalies: Calendar anomaly is another type of anomaly in which various effects are included. In January effect, general and small stocks perform abnormally better in the month of January. Philippe Jorion and Robert Haugen say that, the January effect is, perhaps the best-known example of anomalous behaviour in security markets throughout the world. An interesting fact about January effect is that it lasted for nearly two decades whereas any anomaly hardly survive as traders start taking advantage of the anomalies which results in vanishing of anomaly. Another effect named Turn of the Month was founded by Chris R. Hensel and William T. Ziemba, according to which, in between period 1928 to 1993, the returns for the turn of the month performed well and considerably greater than normal performance. According to study, those investors who make regular purchases may be benefitted if they make schedule to do the purchasing at the end and prior to the starting of next month. In addition to these effec ts another effect is known as Monday effect and is considered to be the worst day in stock market if investments are made on this day. According to study conducted by Lawrence Harris, the week end effect occurs during first 45 minutes of buying and selling whereas prices shows upward trend during the first 45 minutes of trading on all other days. This kind of anomaly may occur due to moods and behaviour of people after weekend holidays. Other Anomalies There are certain other facts that are responsible for affecting the operations of stock market. The size effect, announcement based effect, IPOs, Stock buybacks, insider transactions and S and P game. According to Fama and French (1992), the book to market ratio as well as the size capture the cross-sectional variation of average stock returns in NYSE, and Nsdaq securities. A complete investigation of book to market was provided by Tim Loughran in relation to dimensions of firm size, exchange listings etc and experimental findings of French and Fama are basically forwarded by two features of the data which includes relatively low returns on small, new and growing stocks. Srinivas Nippani, Augustine C. Arize study three main US corporate bond market indices by taking into account calendar based anomalies between the years 1982-2002. In the analysis, the whole bond market as well as two broad classes of industries namely industrials and utilities were taken into account. The study find the mixed response for the weekend effect in the overall bond index and industrial index whereas very less response to utilities index. The findings showed definite proof of January effect on the bond market. RESEARCH METHOD AND DATA: Data Collection Methods: The general idea of business research is that it is concerned with collection of data, making questionnaires and then analysing and evaluating the collected data. In addition to this, the identification of problem and the approach needed to solve the problem is also important. (Ghauri et al., 1995). Data sources are often referred to as the carriers of data information. Basically data sources are divided into two categories namely primary data and secondary data. Primary data is concerned with the interviews and observations collected while conducting research project where as, secondary data is collected by others and academic and non academic sources are included in this type of data. In my topic of research which is to study the efficiency of stock market, I want to use the Desk method that is secondary data collection method. This includes the gathering of information from sources like books, journals related to my topic of research, and from electronic media like internet which is one of the major sources of information. These all sources of information will be helpful for the accomplishment of my research. DATA SOURCES: As I have already describe that I will use secondary method in my dissertation so I have to search a lot for this topic and for this search my main resource is FBES (Faculty of Business, Environment and Society) which provides the best online business information services which is also including the digital management library. Some of the main sources (journal databases) for my research area are given below: EBSCO Business Source. Business Source Premiere. Emerald. Science Direct. NetLibrary. Overall these cover hundreds of journals, and give access to up to a million journal articles. EXPECTED OUTCOMES: While reviewing all the information from available literature on efficient market hypothesis, operations of stock market, price fluctuations and the anomalies of stock market, I have come to the conclusion that the following outcomes could be possible and predictable from my research, If the stock market is efficient then no information can play any role in making any change towards the performance of stock market. The efficient market hypothesis is expected to take any of the following forms which are weak, semi-strong and strong which purely depends upon the availability, and trueness of the past and present information about the stock concerned in the stock market. The anomalies like technical anomalies could be of great help to the researchers and analysts to predict the changing trend in the prices of stocks in the stock market but the transaction cost is the cause of concern while using such technical method. There are some other stock market anomalies which purely depend upon the internal and external factors of the entity and may result in fluctuations in the stock market. The anomalies related to stock market exist for short period of time but function against the concept of efficient market hypothesis and in my research I will find out the facts relating to the vibrations in the stock market as a result of these anomalies. LIMITATIONS AND EXPECTED DIFFICULTIES: While conducting my research I have to face certain difficulties and limitations which may occur during the course of my research. As my research involves the collection of secondary data, I have to be quite aware of the limitations that may arise due to the nature of data. Some of the limitations that are possible are as follows It could be possible that the theory and data we collected for our research is unclear and is not helpful for the companies in their decision making. It is important to check the source of the information as it could be wrong and misleading. It is possible that the theory is quite old for studies and research purposes in todays rapidly developing world. The theory may not be fit for application due to development of new and technological methods and techniques used for the analysis. REFERENCES: Chris R. Hensel and William T.

Efficient Market Hypothesis Efficient Market Hypothesis Literature Review 2.0 Introduction In order to better understand the origin and the idea behind the Efficient Market Hypothesis (EMH), the first section deals with an overview of the EMH. Section 2 deals with the Random Walk Model which is a close counterpart of the EMH. We then have examine the different degrees of information efficiency that exist, namely the weak form efficiency, semi-strong form efficiency and the strong form efficiency. In section 4, we have a brief overview of the different types of statistical tests that have been used in the literature to examine the weak form efficiency. Section 5 explains the implications of efficient markets for investors. 2.1 Efficient Market Hypothesis (EMH) The concept of efficiency is one of the essential concepts in finance. Market efficiency is a term used in many different contexts with many different meanings. Market efficiency involves three related concepts- allocation efficiency, operational efficiency and informational efficiency. Allocation efficiency: A characteristic of an efficient market in which capital is allocated in a way that benefits all participants. It occurs when organizations in the public and private sectors can obtain funding for the projects that will be the most profitable, thereby promoting economic growth Operational efficiency: A marketcondition that exists when participants can execute transactions and receive services at a price that fairly equates to the actual costs required to provide them.Economists use this term to describe the way resources are employed to facilitate the operation of the market. It is usually desirable that markets carry out their operations at as low a cost as possible. Information efficiency: The actual market price of a share should reflect its intrinsic value. Information efficiency implies that the observed market price of a security reflect all information relevant to the pricing of the security. The investor can manage to earn merely a risk-adjusted return from his investment, as prices move instantaneously and in an unbiased manner to any news. The efficiency in the market for financial assets and assets returns refers here to the information efficiency and should not be confused with the other types of efficiency. As explained by Rahman and Hossain (2006): For a stock market to be efficient, stock prices must always fully reflect all relevant and available information. This definition can be expressed as Æ’(Ri,t, Rj,t à ¢Ã¢â€š ¬Ã‚ ¦ à ¢Ã¢â€š ¬Ã‚ ¦ à ¢Ã¢â€š ¬Ã‚ ¦ | à Ã¢â‚¬  M t-1) = Æ’( Ri,t, Rj,t à ¢Ã¢â€š ¬Ã‚ ¦ à ¢Ã¢â€š ¬Ã‚ ¦ à ¢Ã¢â€š ¬Ã‚ ¦ | à Ã¢â‚¬  M t-1, à Ã¢â‚¬  a t-1), where Æ’(.) = a probability distribution function, Ri,t = the return on security i in period t, à Ã¢â‚¬  M t-1 = the information set used by the market at t à ¢Ã¢â€š ¬Ã¢â‚¬Å" 1, à Ã¢â‚¬  a t-1 = the specific information item placed in the public domain at t à ¢Ã¢â€š ¬Ã¢â‚¬Å" 1. This equation has two important implications. 1. Specific information item at t-1 (à Ã¢â‚¬  a t-1) cannot be used to earn non zero abnormal return. 2. When a new information item is added to the information set à Ã¢â‚¬  M, it is instantaneously reflected on market prices. The concept of market efficiency was first introduced by Bachelier (1900). Since then, there has been many studies like Working (1934), Cowles and Jones (1937), Kendall (1953), Cootner (1964). However it was Fama (1965) who first used termed it as à ¢Ã¢â€š ¬Ã…“efficient marketà ¢Ã¢â€š ¬Ã‚ . Fama (1970) later stated the sufficient but not necessary conditions for efficiency: i. there are no transaction costs in trading securities; ii. all available information is costlessly available to all market participants, and iii. all agree on the implications of current information for the current price and distributions of future prices of each security He also identified three degrees of informational efficiency namely the weak form, the semi-strong form and the strong form. 2.2 Random Walk Model (RWM) The Random Walk Model is a close counterpart of the Efficient Market Hypothesis. The model was originally examined by Kendall (1953). It states that stock price fluctuations are independent of each other and have the same probability distribution. Thus the Random Walk theory suggests that stock price change randomly, making it impossible to predict stock prices. The Random Walk Model is linked to the belief that markets are efficient and that investors cannot beat or predict the market because stock prices reflect all available information and the new information arises randomly. As mentioned in Fama (1970) the two hypotheses constituting the Random Walk Model , that is (i) successive price changes are independent and (ii) successive changes are identically distributed, are implicitly assumed in the Efficient Market Hypothesis. The Random Walk Model is in direct opposition to technical analysis, which suggests that a stocks future price can be forecasted based on historical information through observing chart patterns and technical indicators. 2.3 Forms of Market Efficiency 2.3.1 Weak-Form Efficiency Fama (1970) stipulates that no investor can earn excess returns by formulating trading strategies based on historical price or return information in a weak-form efficient market. The weak-form efficiency thus assumes that the price of a stock fully reflects all information contained in past prices, that is the historical sequence of prices, rate of returns and other historical market information. A weak-form efficient market implies that it is of no use to engage in technical analysis that use past prices alone to find undervalued stocks. In order to test whether past share prices can be used to predict future share prices( that is, weak-form efficiency), statistical or econometric tests can be used. These studies seek to study the evolution of share prices from one period to the next period and try to detect correlation between the successive price changes. Technical analysts study the evolution of past share prices, with the aim of predicting share prices to make gains. 2.3.2 Semi-Strong Form Efficiency Fama (1970) described the semi-strong form efficiency as one where share price fully reflect all information contained not only in past prices but all public information. All public information includes capital market information as used in the weak form Efficient Market Hypothesis(EMH) as well as non-market information such as earnings, dividend announcements, price earnings ratio, information about the economy and political news (Reilly1997). New public information is almost instantaneously integrated in share price and the share price is adjusted so as to reflect the true value of the share. This means that an investor cannot use public information to generate gains on the stock market. In order to test for semi-strong form efficiency, event studies are often used. These event studies are performed by analyzing the effect of the release of new public information on the share price. If the market is semi-strong form efficient, the new public information ( for example annual reports, earning announcement or dividend announcement) is instantaneously integrated in the share price, so as to reflect the intrinsic value of the share. New information can be both good or bad. Thus they can cause increases or decreases at their release. 2.3.3 Strong Form Efficiency Under strong form efficiency, the current price reflects all information, public as well as private. Private information, in this context, means information not yet published. On the stock market, there are professionals (for example security analysts, fund managers) who have private as well as public information. Efficient Market Hypothesis (EMH) assumes that no investor has monopolistic access to any information. This means that as new public and private information is released, it is incorporated in share price to reflect its true value. An investor will not be able to consistently find undervalued or overvalued shares and make gains on the strong form efficient market. Fama (1970) perceives a strong form efficient market as one where investors are not expected to earn excess returns by relying on inside information. To test whether past share prices, public and private information can used to predict future share prices, the investment records and gains generated by professional investors are often studied. Investors should not be consistently able to make gains by using public and private information. At all moments, the share prices incorporate all public and private information to reflect the true value of the shares. 2.4 Statistical Tests to examine validity of Weak-Form EMH In order to examine the validity of the weak form efficiency, a number of statistical tests have been used in the literature. These tests can be categorized into two groups: i. Using mechanical trading rules also known as filter rules. These rules test for the possibility of non-linear dependence existing in the price data. Filter rules were first used by S.A Alexander (1961) and later Fama and Blume (1966) added to the literature. Professor Alexanders filter techniques attempts to apply a sophisticated criteria to identify movements in stock prices. An x percent filter is defined as follows: If the daily closing price of a particular security moves up at least x percent, buy and hold the security until its price moves down at least x percent from a subsequent high, then sell and go short (Fama and Blume, 1966). The short position is then maintained until the daily closing price rises at least x percent above a subsequent low when one is going to cover and buy. Moves less than x percent in either direction are ignored. ii. Statistical tests of independence between successive price changes. Serial autocorrelation tests and run tests are among the most popular tests. Some of the researches in this field use Spectral Analysis which decomposes a time series into a spectrum of cycles of different length. This spectral decomposition of a time series yield a spectral density function that measures the contribution of each of the frequency bands to the overall variance of the times series. There is also a relatively new test introduced by Lo and Mackinlay (1988), it is called the Variance Ratio which is based on the heteroscedasticity problem. The basic idea behind the Lo and Mackinlay (1988) variance-ratios test is that if a natural logarithm of a time series is a pure random walk, then, the variance of its k-differences in a finite sample grows linearly with the difference, Let (pt) denote a time series consisting of T observations p1,p2,à ¢Ã¢â€š ¬Ã‚ ¦,pT of asset returns. Then, the variance-ratio of the k-th difference, VR(k), is defined as: VR(k)= à Ã†â€™2(k)/à Ã†â€™2(1) where, VR(k) is the variance-ratio of the shares returns k-th differences; à Ã†â€™2(k) is the unbiased estimator of 1/k of the variance of the shares returns k-th differences, under the null hypothesis; à Ã†â€™2(1) is the variance of the first-differenced share returns series, and k is the number of days of base observations interval or lag (Ntim et al. ,2007). 2.5 Implications of EMH Market efficiency has important implications for both investors and authorities. If a market is inefficient, investors should doubt the à ¢Ã¢â€š ¬Ã…“hold the marketà ¢Ã¢â€š ¬Ã‚  strategy and should try to à ¢Ã¢â€š ¬Ã…“beat the marketà ¢Ã¢â€š ¬Ã‚ . While the authorities on their part should restructure the stock market by enacting effective law and enhancing financial media. The graph below shows the effect of EMH on stock prices. The straight line shows the reaction under EMH while the dotted lines show the over-reaction and under-reaction that occur with the existence of market imperfections. If a market is efficient, investors: 1. should not worry about investment analysis. They should rather concentrate on holding a well diversified portfolio. Investors holding an inefficient diversified portfolio will be exposed to risk which could be avoided and for which they will not be rewarded. In other words, the market only provides return for systematic risk, while specific risks have to be diversified away. 2. Should adopt a buy and hold policy once they have established their portfolios. This is because there is no advantage in changing from one group of securities to another. By doing this, there would be transaction costs which they would have to incur and as a result, the risk-adjusted return would be affected. Altering the composition of a portfolio can only be justified a) if the risk exposure has changed due to relative changes in the market value of the constituent securities. b) if tax payments can be minimized. Other implications of EMH are: Price changes are random and unpredictable Investors are not easily fooled by the glossy financial reports or à ¢Ã¢â€š ¬Ã‹Å"creative accounting techniques Timing of new issues of securities are not important since prices represent the intrinsic and will reflect the degree of risk in the share. Thus under EMH neither fundamental nor technical analysis can be used to achieve superior gains. Investors should concentrate on constructing and holding efficiently diversified portfolios. 2.6 Empirical Evidences Based on the literature, it can be seen that there are two competing schools of thoughts about market efficiency. The first school argues that markets are efficient and as a result, returns cannot be predicted. For example early studies (Working, 1934; Kendall, 1943, 1953; Cootner, 1962; Osborne, 1962; Fama, 1965) on developed markets support the weak form efficiency of the market with a low degree of serial correlation and transaction cost. The studies in this school of thought, support the Efficient Market Hypothesis (EMH) and show that price changes could not be used to forecast future price changes, especially after transaction costs were taken into account. The second school, on the other hand, provides empirical evidence of à ¢Ã¢â€š ¬Ã‹Å"anomalies that contradict the theory of efficient markets. Some of these studies are Summers (1986), Keim (1988), Fama and French (1988), Lo and MacKinlay (1988) and Poterba and Summers (1988). They found some à ¢Ã¢â€š ¬Ã‹Å"anomalies, which could not be explained by the theory of Fama (1965). Some of the market anomalies that they found are: January Effect/Turn of The Year Effect Stock returns are usually abnormally high during the first few days of January. The January effect occurs because many investors choose to sell some of their stock right before the end of the year in order to claim a capital loss for tax purposes. Then they quickly reinvest their money after the new year, causing stock prices to rise. Rozeff and Kinney (1976) was among the first to prove this market anomaly. Rozeff and Kinney (1976) methodology gives smaller companies greater relative influence than would be true in value-weighted indices where large firms dominate. Subsequent researches (Reinganum, 1983; Roll, 1983, among others) later confirm that the January effect is a small cap phenomenon. Size Effect/Small Firm Effect The Size Effect is the tendency for firms with a small market capitalization to outperform larger companies over the long term. For example Banz (1981) and Reinganum (1981) showed that small-capitalization firms on the New York Stock Exchange (NYSE) earned a return in excess of what would be predicted by the Sharpe (1964) Linter (1965) capital asset-pricing model (CAPM) from 1936-1975. However as mentioned by G.W. Schwert (2003, p.943), it seems that the small-firm anomaly has disappeared since the initial publication of the papers that discovered it. Alternatively, the differential risk premium for small-capitalization stocks has decreased over the years. Weekend Effect/Day of The Week Effect This is a phenomenon in which stock returns on Mondays are often significantly lower than those of the immediately preceding Friday. French (1890) observed this anomaly. He noted that the average return to the Standard and Poors (SP) Composite Portfolio was reliably negative over weekends in the periods 1953-1977. Again, like the size effect, the weekend effect seems to have disappeared, or at least substantially attenuated, since it was first documented in 1980. Value Effect/Price Earnings Ratio Effect The value effect refers to the tendency for stocks with low price earnings ratio to outperform portfolios consisting of stocks with a high price earnings ratio. Basu (1977) shows that investors holding low price earnings ratio portfolio earned higher returns. The existence of market anomalies have important implications. If stock returns do not follow a random process, then it is possible to design profitable trading strategies based on historical information 2.6.1 Empirical Evidences from Developing Countries Despite the large number of empirical studies that have been conducted to test the validity of the Efficient Market Hypothesis (EMH) in developed countries with booming financial markets, studies to support or dispute the efficiency or inefficiency of the African stock markets are quite limited. There is a small number of empirical studies analyzing emerging African equity markets with regards to weak form of market efficiency test. While some of these studies have analysed single markets ( e.g. Samuels and Yacout 1981; Parkinson 1984; Ayadi 1984; Dickinson and Muragu 1994; Osei 1998; Olowe 1999; Mecagni and Sourial 1999; Asal 2000; Adelegan, 2004; Dewotor and Gborglah, 2004; Ntim et al., 2007), others have analysed groups of countries (e.g. Claessens et al., 1995; Magnusson and Wydick, 2002; Smith et al., 2002; Appiah-Kusi and Menya, 2003; Simons and Laryea, 2004; Jefferis and Smith, 2005). However, while there are only a few empirical studies, their conclusions as to the efficiency and predictability of future stock returns have been mixed. For example Dickinson and Muragu (1994) shows that the Kenyan stock market is weak form efficient, in contrast to the results of Parkinson (1984). Also, most of the existing studies made use of conventional weak form testing techniques such as serial correlation tests. Samuels and Yacout (1981) and Parkinson (1984) were among the first to use serial correlation tests to examine the weak form efficiency on the African continent. Samuels and Yacout analysed the weak form market efficiency in weekly price series of 21 listed Nigerian firms from 1977 to 1979 and provided empirical evidence that the market was efficient. Parkinson on his part, analysed monthly price series of 30 listed Kenyan firms from 1974 to 1978 and rejected the weak form efficiency. Dickinson and Muragu (1994) reinvestigated the Kenyan market by applying run and serial correlation tests to weekly stock price series of 30 listed companies on the Nairobi Stock Exchange and their results were in contrast with Parkinson (1984). They demonstrated that successive price changes are independent of each other for the majority of the companies investigated. Most of the developing countries suffer from the problem of thin trading (Mlambo and Biekpe, 2005). The problems caused by thin trading have been widely acknowledged in financial market researches (e.g., Dimson, 1979; Cohen et al. ,1983; Butler and Simonds, 1987; Lo and Mackinlay, 1990a and b; Bowie, 1994; Muthuswamy and Whaley, 1994) . Fisher (1966) who was the first to identify the bias caused by thin trading in the serial correlation of index returns, explained that recorded prices of securities are not necessarily equal to their underlying theoretical values. This is because when a share does not trade, the price recorded remains the closing price when the share was last traded. However, while most of the African stock markets suffer from thin trading, many existing studies fail to adjust for thin trading. For example recent studies conducted on the Stock Exchange of Mauritius (Appiah-Kusi and Menya, 2003 and Simons and Laryes, 2004) made used of conventional techniques and did not adjust for thin trading. Other studies (Kabba, 1998; Roux and Gilberson, 1978 and Poshawale, 1996) which have examined the behavior of stock price and rejected the weak-form efficiency, have explained that the inefficiency might be due to delay in operations and high transaction cost, thinness of trading and illiquidity in the market.

hippies :: essays research papers fc

â€Å"Old hippies don't die, they just lie low until the laughter stops and their time comes round again.†(Stolley 238) Counterculture by definition is a culture, especially of young people, with values or lifestyles in opposition to those of the established culture. Counterculture way of life in the 1960s featured the ideas of, peace, love, music, drug use, freedom of sexuality, and much more, these ideas were mostly associated with the hippies. Hippies were mostly rebellious young people who wanted a change in there life style. Hippies experimented with many new ideas for the sixties. The Hippie-movement started in San Francisco in the 1960’s. It was an alternative way of life. The Hippie-movement was an uprising, display against war, and it was spreading the message of love and peace. Many Americans disagreed with the Hippy way of life mostly because of there beliefs of free sex, drugs, their music and their clothes. The hippy-revolution stunned many people The Life of the hippies was adverse to all authoritarian higher power structures since they are adverse to the hippie goals of peace, love and freedom. This is why the "Establishment" feared and covered up the hippie movement of the '60s, as it was a rebellion against the well-known order. Hippies did no believe in the routine 8 to 5 way of life and therefore were targets of hatred by the people who live there life that way. Nearly all hippies were without a job and got by everyday with help from the public social services. Hippies tried to change the world through reason and by staying true to what they believed. The Hippies had many philosophy’s in life, one of there core philosophy was, â€Å"Loving means accepting others as they are, giving them freedom to express themselves and not judging them based on appearances.†(Stolley 240) Bibliography 1969 Woodstock.

George Orwells Animal Farm Essay -- George Orwell Animal Farm Essays

George Orwell's Animal Farm George Orwell wrote ‘Animal Farm’ as an allegory, which is a simple story, with a more complicated idea running alongside it. In this case, it is a story about a group of pigs taking over a farm, and the story of the Russian Revolution is told underneath it. The main characters of the revolution are portrayed in the book as follows: Mr Jones is Czar Nicholas II, the last Russian leader before the revolution; Old Major is Karl Marx, the person who influenced the people into revolting and the idea of communism; Snowball is Trotsky, one of the early leaders of the revolution; Napoleon is Stalin, a cruel, selfish, and corrupt leader; and Boxer and Clover represent the proletariat, or the ‘common’ working class people. At the beginning of the book, Boxer is introduced as ‘an enormous beast’, who is ‘not of first rate intelligence’, and we are also told that he is universally respected. He has a kind, gentle, caring character that others feel safe around ‘Last of all came the cat, who looked around, as usual, for the warmest place, and finally squeezed herself in between Boxer and Clover.’ Boxer and Clover are used by Orwell to represent the proletariat, or the working class, in Russian society. This lower class is naturally drawn to Stalin (represented by Napoleon) because it seems as though they will benefit most from his new system. Since Boxer and the other low animals are not accustomed to the "good life," they can't really compare Napoleon's government to the life they had before under Jones. The proletariat are also quite good at convincing each other that communism is a good idea, ‘they absorbed everything that they were told, and passed it on to the others’. Boxer... ...nd of the book shows how the leaders of the Russian Revolution turned out to be just as bad, if not worse than the czars, ‘The creatures outside looked from pig to man, and from man to pig, and from pig to man again: but already it was impossible to say which was which.’ George Orwell put Boxer in the story and killed him to show that all his hard work, like the proletariats in the Russian Revolution, was for nothing and that, in the end, it would always go back to the way it was at the beginning. This is something that Benjamin knew all the way through, and after the animals have forgotten Jones and their past lives, ‘Only old Benjamin professed to remember every detail of his long life and to know that things never had been, nor ever could be much better or much worse; hunger, hardship, and disappointment being, so he said, the unalterable law of life.’

The Enron Implosion and the Loss of Respect for the Accounting Professi

The Enron Implosion and the Loss of Respect for the Accounting Profession On the surface, the motives behind decisions and events leading to Enron’s downfall appear simple enough: individual and collective greed born in an atmosphere of market euphoria and corporate arrogance. Hardly anyone—the company, its employees, analysts or individual investors—wanted to believe the company was too good to be true. So, for a while, hardly anyone did. Many kept on buying the stock, the corporate mantra and the dream. In the meantime, the company made many high-risk deals, some of which were outside the company’s typical asset risk control process. Many went sour in the early months of 2001 as Enron’s stock price and debt rating imploded because of loss of investor and creditor trust. Methods the company used to disclose its complicated financial dealings were all wrong and downright deceptive. The company’s lack of accuracy in reporting its financial affairs, followed by financial restatements disclosing billions of dollars of omitted liabilities and losses, contributed to its downfall. The whole affair happened under the watchful eye of Arthur Andersen LLP, which kept a whole floor of auditors assigned at Enron year-round. In 1985, after federal deregulation of natural gas pipelines, Enron was born from the merger of Houston Natural Gas and InterNorth, a Nebraska pipeline company. In the process of the merger, Enron incurred a lot of debt and, as the result of deregulation, no longer had exclusive rights to its pipelines. In order to survive, the company had to come up with a new and innovative business strategy to generate profits and cash flow. Kenneth Lay, CEO, hired McKinsey & Co. to assist in developing Enron’s business strategy. It assigned Jeffrey Skilling to the task. Skilling, who had a background in banking and asset and liability management, proposed a revolutionary solution to Enron’s credit, cash, and profit worries in the gas pipeline business: create a â€Å"gas bank† in which Enron would buy gas from a network of suppliers and sell it to a network of consumers, contractually guaranteeing both the supply and the price, charging fees for the transactions and assuming the associated risks. Thanks to the young consultant, the company created both a new product and a new paradigm for the industry—the energy derivative. Lay was so impressed with Skilling’s ... ... excellence stand in satirical contrast to allegations now being made public. Personally, I had referred several of our best and brightest accounting, finance and MBA graduates to Enron, hoping they could gain valuable experience from seeing things done right. These included a very bright training consultant who had lost her job in 2000 with a Houston consulting firm as a result of a reduction in force. She has lost her second job in 18 months through no fault of her own. Other former students still hanging on at Enron face an uncertain future as the company fights for survival. The old saying goes, â€Å"Lessons learned hard are learned best.† Some former Enron employees are embittered by the way they have been treated by the company that was once â€Å"the best in the business.† Others disagree. In the words of one of my former students who is still hanging on: â€Å"Just for the record, my time and experience at Enron have been nothing short of fantastic. I could not have asked for a better place to be or better people to work with. Please, though, remember this: Never take customer and employee confidence for granted. That confidence is easy to lose and tough—to impossible—to regain.†
