Prior studies document that book-tax differences (BTDs) reflect divergent reporting rules for book and tax purposes, and contain information about earnings management and tax planning. In this paper, we investigate whether the regulatory and opportunistic information impounded in BTDs...

Purpose – The purpose of this paper is to present a behavioral explanation of excess stock price volatility relative to present value theory. Design/methodology/approach – The conceptual basis is the impact of affect on investor decisions. The empirical tests involve survey data collected...

The question of whether empirical models are able to forecast the equity premium more accurately than the simple historical mean is intensively debated in the nancial literature. The low prediction power is disappointing, even when using nonparametric models that make use of typical predictor...

If stock markets are efficient then it should not be possible to predict stock returns, i.e., no explanatory variable in a stock market regression model should be statistically significant. In this study, we find results indicating that daily effects exist in stock market returns. These daily or...

This paper examines the relation between oil price changes and stock returns. By using recently developed frequency domain methods, the study shows that there is significant time variation in the linkage between oil and equities. Oil price shocks with less than 12-month persistency have a...

Abrupt changes in the unconditional variance of returns have been recently revealed in many empirical studies. In this paper, we show that traditional KPSS-based tests have a low power against nonstationarities stemming from changes in the unconditional variance. More precisely, we show that...

Kim, Shephard, and Chib (1998) provided a Bayesian analysis of stochastic volatility models based on a fast and reliable Markov chain Monte Carlo (MCMC) algorithm. Their method rules out the leverage effect, which is known to be important in applications. Despite this, their basic method has...

This paper is an attempt to explore the relationship of CSR and firms’ financial performance in Greek firms. Based on stakeholder theory and mainly on the theory of “good management”, we try to find out if an improvement in CSR actions results in higher stock returns. Our empirical...

A Bayesian analysis of a stochastic volatility model with a generalized hyperbolic (GH) skew Student’s t-error distribution is described where we first consider an asymmetric heavy-tailed error and leverage effects. An efficient Markov chain Monte Carlo estimation method is described that...

This paper investigates the information content of analysts’ earnings forecast revisions for Brazilian companies, defined as the ability to change stock prices. Using data from I/B/E/S and Economatica covering the period from 1995 through 2002, we find that forecast revisions that follow the...
