Kim (1995) provides a sufficient condition to rank information systems when the first-order approach is valid. The basis for the condition is the comparison of the likelihood ratio distributions. I show, first, that Kim’s criterion is not necessary when the limited liability of the agent...

In an agency model with moral hazard and limited liability, we show that the provision of perks can be inefficient, even if perks are contractible. Interestingly, there can be over- as well as underinvestment in perks. We also demonstrate that perks may actually harm the agent, although perks...

This experiment shows that varying the commission received by financial advisors strongly influences insurance purchase.

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

We analyze a strategic trading model where an overconfident insider is required to publicly disclose his trades after the fact. We find the more confident insider is more concerned about the effect the initial trading has on the future.

In the present study, I explore the dynamics of the interday stock price reversals. Employing the intraday price data on thirty stocks currently making up the Dow Jones Industrial Index, I document that daily stock returns tend to be higher following the days with relatively large high-to-close...

Most socially responsible investment funds combine a sustainability objective with a tracking error constraint. We characterize the impact of a sustainability constraint on the mean-tracking error efficient frontier and illustrate this on a universe of US stocks for the period 2003–2010.

We use extreme value theory to analyse the tails of a momentum strategy’s return distribution. The asymmetry between the fat left tail and thin right tail strongly reduces a momentum strategy’s prospective utility levels.

This paper contributes to the understanding of the non-linear causal linkage between investors’ sentiment dynamics and stock returns for the US economy. Employing the sentiment index developed by Baker and Wurgler [Baker, M., Wurgler, J., 2007. Investor sentiment in the stock market. Journal...

In this research I examined a calendar anomaly that occurs at the beginning of each quarter. Through an examination of 34 years of daily and annual returns for the S&P500 and 13 years of returns for popular ETFs, I have demonstrated the existence of the First Day of Quarter (FDQ) effect. By...
