Through explicitly incorporating analysts' forecasts as observable factors in a dynamic arbitrage- free model of the yield curve, this paper proposes a framework for studying the impact of shifts in market sentiment on interest rates of all maturities. An empirical examination reveals that...

This paper uses factor analytic techniques for deriving factor realizations from a group of main economic indicators of both the German and the Turkish economy in order to test the effect of economic factors on asset returns in an APT framework. The factor structure of the German economy yields...

In this paper we compare market prices of credit default swaps with model prices. We show that a simple reduced form model with a constant recovery rate outperforms the market practice of directly comparing bonds' credit spreads to default swap premiums. We find that the model works well for...

We show how payoff spaces can be used to study minimum-variance unbiased estimators and give a proof of Barankin's theorem for finite sample spaces and for samples of size one.

Behavioral Finance aims to explain empirical anomalies by introducing investor psychology as a determinant of asset pricing. This study provides strong evidence that anomalous stock price behavior following earnings announcements is due to a representativeness bias. It investigates current and...

We present a simple model of a stock market where a random communication structure between agents gives rise to a heavy tails in the distribution of stock price variations in the form of an exponentially truncated power-law, similar to distributions observed in recent empirical studies of high...

Les travaux en finance comportementale tentent, depuis quelques années, d'expliquer certaines des anomalies constatées, en abandonnant l'idée de rationalité de l'investisseur, pourtant centrale à l'hypothèse d'efficience des marchés. Cette étude, menée sur les entreprises américaines...

This paper examines the forecasting performance of GARCH’s models used with agricultural commodities data. We compare different possible sources of forecasting improvement, using various statistical distributions and models. We have chosen to confine our analysis on four indices which are the...

This paper reconsiders return-volume dependence for the U.S. and six international equity markets. We contribute to previous work by proposing surprise volume as a new proxy for private information flow and apply extreme value theory in studying dependence for large volume and return, i.e. under...

This paper proposes tests of unconditional mean-variance efficiency using bootstrap method that does not depend on specific distributional assumptions. We reject the mean-variance efficiency of the CRSP value- weighted stock index for five of the seven consecutive ten-year subperiods from 1926...
