Overcon dence and Diversi cation
Experimental evidence suggests that people tend to be overcon dent in the sense that they overestimate the accuracy of their private information. In this paper we show that risk-averse principalsExpand
Overconfidence and Diversification

Persistence and heterogeneity in entrepreneurship: An evolutionary game theoretic analysis
Studies show that countries exhibit a relatively stable level of entrepreneurial activity. To account for this fact, we adopt an evolutionary game theoretic approach. Based upon the analysis of gamesExpand
Contract Horizon and Turnover
