The paper develops a theory which attempts to understand segmentation and fee-setting in certification markets. The basis for the theory is that certifiers offer differentiated tests; for a given object it may be more difficult to pass the test of certifier i than the test of certifier j. Given...

I consider two seemingly unrelated puzzles; 1.Why is relative performance evaluation (RPE) used less in CEO compensation than agency theory suggests? 2.Why is sometimes, e.g., for fund managers, a mediocre performance more highly rewarded than excellence? I consider a simple tournament model,...

If entrepreneurs are liquidity constrained and not able to borrow to operate on an efficient scale, economic theory predicts that entrepreneurs with more personal wealth should do better than those with less wealth. We test this hypothesis using a novel data set covering a large panel of...

In the large literature on firm performance, economists have given little attention to entrepreneurs. We use deaths of more than 500 entrepreneurs as a source of exogenous variation, and ask whether this variation can explain shifts in firm performance. Using longitudinal data, we find large and...

A tradition from Knight (1921) argues that more risk tolerant individuals are more likely to become entrepreneurs, but perform worse. We test these predictions with two risk tolerance proxies: stock market participation and personal leverage. Using investment data for 400,000 individuals, we...

We study how firm-specific complementary assets and intellectual property rights affect the management of knowledge workers. The main results show when a firm will wish to sue workers that leave with innovative ideas, and the effects of complementary assets on wages and on worker initiative. We...

I study how education affects the allocation of talent into different sectors of the economy. I focus on two forces. First, education adds to a worker's information capital and, thus, may change her self-confidence. Second, performance contracts give a worker incentives to choose a sector...
