The middle period of the 20th century, the births of electronic calculator and information transmission technology, let the civilized development course be faster. Under the situation in the considerable and significant growth of product-producing and cultural dissemination , the compatibility of products is shaped into the top theme that sought together by customers and manufacturers .The growth of the diverse products in markets gives a chance of option to the users in markets .This research shows that it will only be after undergoing the marketable course of competition certainly when every manufacturer introduces the products , could determines that whether it's a market that monopolize or a situation that is formed by the incompatibility of every product from each manufacturer. Based this background, The research was done by using language Visual Basic to write a function about marketing share¡Buser preference ¡Btechnology and strategy to confer when ¡Bwhy and how the competing technologies will become Monopoly or have marketing shares with each other in a long period. From the conclusion of this research, we know what will the firms do under the supposition of this research and there is the description about the limit in this research and the feasibility study in the future.

The finding of reversals in weekly returns has been attributed to a combination of microstructure issues and overreaction to information. I provide new evidence eliminating overreaction as a source of reversal. I show that well-known weekly contrarian profits are followed by a long run of momentum profits. In fact, these profits are strong enough to produce a significant momentum effect over the full year following portfolio formation. Thus, the market does not appear to view extreme weekly returns as excessive, as implied by an overreaction story. To the contrary, this return continuation is consistent with underreaction to the news driving extreme weekly returns. This is supported by cross-sectional tests in which I find this week's news is positively related to next week's returns. The evidence presented here is consistent with growing evidence that underreaction to firm-specific information is a pervasive feature of price formation. Therefore, if any short-run contrarian profits can be realized, they are better viewed as compensation for providing liquidity than as a reward for arbitrage.

This dissertation examines the literature that attempts to measure the relationship between school quality and earnings. I begin by developing a simple economic model that predicts that, everything else being equal and with comparisons being made within a market, workers from higher quality schools will have higher earnings among those with the same level of schooling and they will have steeper schooling-earnings gradients. The remainder of this dissertation explores problems that exist in this literature for which no solutions have been presented. These problems include: 1) there doesn’t have to be a direct and positive relationship between school quality and earnings; 2) the data suggest that school quality measures are frequently mismatched to workers; 3) most school quality studies include college-trained labor while completely ignoring the quality of the college attended; 4) the omission of college quality from the estimation is especially problematic for studies that attempt to measure the school quality-earnings relationship through differences in schooling-earnings gradients for those educated in different systems; 5) state of birth wage rankings thought to capture a school quality effect are not invariant to the market (state of residence) in which they are evaluated; and 6) the evidence presented herein suggests that interstate migration is selective. These problems undermine the credibility of existing estimates of a school qualityearnings relationship.

<p>Hedge fund investing is a relatively new phenomenon in Sweden. The first Swedish hedge fund was started in 1996. This new financial sector has since showed a steady growth.</p><p>Due to the novelty of hedge fund phenomena, it is right to ask whether the investors are prepared for this kind of investments; how they choose their hedge funds investments and whether they have adequate knowl-edge in the field.</p><p>This thesis provides a mapping of the investors’ behavior regarding hedge fund investments. We have concluded that Swedish hedge fund investors have a limited basis of knowledge required to fully utilize hedge funds in their portfolios.</p>

In this thesis we analyze the financial performance of Football clubs following an initial public offering (IPO). We conduct several analyses using time series stock data with a focus on finding evidence of long-run underperformance and IPO over/underpricing. To this end, we estimate cumulative abnormal returns (CAR) and Jensen’s Alpha. We also analyze coefficients such as beta to describe the volatility and the link football clubs’ stocks have to the general market. We look at historical events that may have affected the movement of stock prices and confirm this by benchmarking an index (STOXX index) compiled of a number of European football teams. Our results show that football clubs do in fact follow the clear pattern of other entities and sectors and previous research with regard to underperformance in the long run. We find that football clubs’ stocks are less volatile than the general market and have a low beta. With regards to over/underpricing, we only obtain data for a few football clubs. We find small signs of underpricing but are not able to confirm that this is statistical significant due to the size of our sample.

The pricing of total liquidity risk is studied in the cross-section of stock returns. The study suggests that there is a positive relation between total volatility of liquidity and expected returns. Our measure of liquidity is based on Amihud (2002) and its volatility is measured using daily data. Furthermore, we document that total volatility of liquidity is priced in the presence of systematic liquidity risk: the covariance of stock returns with aggregate liquidity, the covariance of stock liquidity with aggregate liquidity, and the covariance of stock liquidity with the market return. The separate pricing of total volatility of liquidity indicates that idiosyncratic liquidity risk is important in the cross section of returns. This result is puzzling in light of Acharya and Pedersen (2005) who develop a model in which only systematic liquidity risk affects returns. The positive correlation between the volatility of liquidity and expected returns suggests that risk averse investors require a risk premium for holding stocks that have high variation in liquidity. Higher variation in liquidity implies that a stock may become illiquid with higher probability at a time when it is traded. This is important for investors who face an immediate liquidity need and are not able to wait for periods of high liquidity to sell.

The current study investigates the relationship between analyst coverage and the moments of the return distribution. Results are presented to support a time-varying pattern in the premiums associated with the higher moments of returns, particularly for the fourth moment of the distribution. In addition, evidence is presented to suggest that there exists some ex-post and ex-ante forecasting ability based on the use of the higher moments of the return distribution as stock selection criteria. In the second half of the study, results show that as the number of analysts following a firm increases, the third and fourth moments of the return distribution are impacted, with the former being reduced and the latter increased. In addition, the initiation and discontinuation of analyst coverage are both found to be related to the higher moments of the return distribution. The initiation of analyst coverage is associated with a reduction in skewness and an increase in excess kurtosis, while the discontinuation of coverage results in an increase in both of the higher moments of the distribution. Taken together, the results of the two main questions in the current research study suggest that investors seeking higher distributional moments of returns may favor neglected firms over their followed counterparts, particularly in periods of heightened market volatility. In addition, the results show that the two main competing hypotheses concerning the causes of non-normal security returns, namely firm information structure and security liquidity, both impact the higher moments of the return distribution. / Thesis (Ph.D, Management) -- Queen's University, 2010-08-26 12:18:47.528

This paper analyzes the relationship between the merger announcement returns and the bidding firms' preparations for mergers. In this study, merger preparations are defined as bidding firms' adaptive actions of changing their executives prior to mergers. An analysis of the relative effectiveness of merger preparations is conducted through event study for univariate tests. In addition, a regression for multivariate tests analyzes incentives for making merger preparations. The results of these studies indicate that (1) hiring of new executives from outside the target proves to be the most effective merger preparation, (2) firms who make merger preparations have higher returns, and (3) hiring of new executives from the targets proves to have negative effects on bidding firms' returns, though this can vary based on the relative size of the target.
