Full textThis thesis is devoted to the link existing between bayesian learning models, human being's processing of information and financial markets' information (in-)efficiency. The first part focuses on the herding literature to prove that a rational processing of information may be sufficient to prevent phenomena of exuberance on financial markets. The second part concentrates on the contribution of cognitive psychology literature and of bayesian learning models to behavioral economics. This analytic frame provides a formal and wellstructured definition of rationality. This allows a certain kind of irrationality to be highlighted from a clear benchmark. The main contribution rests on a bayesian updating model of subjective beliefs where agents process their information in function of the nature of the information they dispose of

Full textThe thesis treats the problem of the informational efficiency of developed countries' stock markets. In the first chapter, we analyse samuelson's equilibria, which have been used to test efficiency since the sixties. The results of these tests, applied to French and American stock markets, are presented in the second chapter. These tests show evidence against the joint hypothesis of informational efficiency and samuelson's equilibria. The third chapter reviews the literature explaining the anomalies, cited in chapter two, by the following models : equilibrium models of rational expectations versus informational inefficiency and irrationality. But none of these theories are fully satisfactory. Indeed, stock markets are informationally efficient but samuelson's model must be replaced by an equilibrium model which deals with rational speculators. The fourth chapter presents the general properties of rational speculation equilibria. In the fifth chapter, we show that this model entails the stylized facts described by the anomalies. Finally, in the sixth chapter, we show that our model can be applied to a particular stock market - the paris stock exchange - for which the joint hypothesis of informational efficiency and rational speculation equilibrium is not rejected

Full textWe investigate the impact of option listing on the underlying stock dynamics and the informational efficiency of the stock market, using data from the French Euronext Paris stock market about new option listing that occurred over the period 1996 – 2006. We take into account the implementation of a new trading system after the Euronext merger with the Liffe market in 2002 and the macroeconomic changes over the period.Considering different characteristics of stocks, we observe (i) no effect on both volatility and systematic risk measured by the beta, (ii) a negative price effect, although insignificant at the majority of times, (iii) a significant rise in the volume and, finally (iv), a significant decrease in the spread bid-ask. By estimating a VAR model, we highlight a better adjustment to new information, observable jointly through contemporaneous and delayed relations between volume and volatility. However, when decomposing volatility into the contributions of informed and non-informed agents, we cannot document any migration of informed traders to the underlying stock market after option listing. We confirm the absence of impact of option listing on the underlying stock pricing efficiency by examining the stock price duration dynamics, using a modified Log-ACD model that accounts for liquidity captured by trade size.On the other hand, we show that in high volatility periods (low volatility periods), the option market plays a hedging role (speculation and/or arbitrage). The implementation of the new trading system after the Euronext merger with the Liffe market in 2002 appears to have no significant impact on the underlying stock. The global result about the absence impact of option listing is justified by the underlying stock’s volatility-driven trading. These strategies disturb the connection between option and underlying stock markets and the predictive power of option prices

Full textAfter providing a general framework of merger‐acquisition, in particular as value‐creating process, we examine empirically the effects of their announcement through three essays. First, we study the intraday market reactions to announcements in the United‐States. We find gains for target firms, while acquiring firms do not earn significant abnormal returns. These results occur in a high trading activity and animprovement of liquidity. Second, we extend the analysis to the competitors of merging firms. Considering the Canadian evidence, the release of information affects negatively their rivals. Third, we study the conditions under which managers are more willing to listen to investors. Analyzing a sample of French acquisitions, we find that the well‐connected managers are more likely to complete a deal in spite of a negative market reaction on acquisition announcement
