Sudden big price changes are followed by periods of high and persistent volatility. I develop a tractable dynamic rational expectations model consistent with this observation. An infinity of agents possess dispersed information about future dividends and trade in centralized markets. Information...

During the last years issues of strategic management accounting have received widespread attention in the accounting literature. Yet the conceptual foundation of most proposals is not clear. This paper presents a theoretical analysis of one of the most prominent approaches of strategic...

Candidates compete to persuade a decision maker. The decision maker wishes toselect a candidate who possesses a certain ability. Then, as a signaling, each candidatedecides whether to perform a task whose performance statistically re‡ects the ability.However, since the cost of the performance...

An apology is a strong and cheap device to restore social or economic relationships thathave been disturbed. In a laboratory experiment we find that harmdoers use apologies inparticular if they fear punishment and when their intentions cannot be easily inferred. Afteroffenses with ambiguous...

We study the value of information in financial markets by asking whether having more information always leads to higher returns. We address this question in an experiment where single traders have different information levels about an asset’s intrinsic value. In our treatments we vary the...

We use learning in an equilibrium model to explain the puzzling predictive power of the volatility risk premium (VRP) for option returns. In the model, a representative agent follows a rational Bayesian learning process in an economy under incomplete information with the objective of pricing...

I consider a consumption based asset pricing model where the consumer does not know if shocks to dividends are stationary (temporary) or non-stationary (permanent). The agent uses a Bayesian learning algorithm with a bias towards recent observations to assign probability to each process. While...

We build an equilibrium model to explain why stock return predictability concentrates in bad times. The key feature is that investors use different forecasting models, and hence assess uncertainty differently. As economic conditions deteriorate, uncertainty rises and investors' opinions...

We consider an exchange economy with two heterogeneous stocks and twogroups of investors. Dividends follow diusion processes, with a constant expectedgrowth rate for one stock and a stochastic drift for the other. 'Rationalinvestors' can either observe this stochastic drift without error or...

We find that price and earnings momentum are pervasive features of international equitymarkets when controlling for data snooping biases. For European countries, we find that pricemomentum is subsumed by earnings momentum on an aggregate level. However, this rationaledoes not apply to each and...
