We develop a Stochastic Dominance methodology to analyze if new assets expand the investment possibilities for rational nonsatiable and risk-averse investors. This methodology avoids the simplifying assumptions underlying the traditional mean-variance approach to spanning. The methodology is applied to analyze the stock market behavior of small firms in the month of January. Our findings sugges...

Do audits by executive agencies impact the behavior of those audited? Does revealing negative information about legislators affect electoral results and behavior? Institutions that encourage transparency, such as campaign finance disclosure, influence mass elite behavior. Campaign transparency provides to voters during legislative campaigns character candidates, this affects voter legislator Th...

My research focuses on corporate finance and behavioral finance and includes empirical and applied theory papers. My work in corporate finance specifically aims at providing clean and novel empirical evidence on the real effects induced by frictions in the market for financing. My main contributions in this area have been to investigate (1) the role of real estate collateral on economic activit...

The paper considers one of the standard processes for modeling returns in finance, the stochastic volatility process with regularly varying innovations. The aim of the paper is to show how point process techniques can be used to derive the asymptotic behavior of the sample autocorrelation function of this process with heavy-tailed marginal distributions. Unlike other non-linear models used in f...

We perform an experimental study of complexity to assess its effect on trading behavior, price volatility, liquidity, and trade efficiency. Subjects were asked to deduce the value of a particular asset from information they were given about the composition and price of several portfolios. Following that, subjects traded with each other anonymously in a well-defined, simple bargaining process. P...

A recent common view of finance experts is that it is becoming increasingly difficult to understand how the economy as a whole works. Although the efficient market theory might be considered an ideal model enabling the interpretation of market behavior, it has begun to lose ground, and the rationality hypothesis failed to explain the excessive volatility of the returns and trading volume record...

Cressey’s [1] fraud triangle examined the motivation for crime. McMahon et al. [2] suggest there is a need to move beyond the traditional fraud triangle to fight white-collar crime. In this article, we suggest a white-crime triangle which includes financial motive, organizational opportunity and deviant behavior. The suggested white-collar crime triangle is based on convenience theory [3], wher...
