We consider the possibility a draft increases the likelihood individuals will invest in human capital in the military. This possibility exists because those drafted have less time to reap the return from human capital investment since, with a volunteer military, one need not enlist. A draft is...

The usual explanations for superstar effects---when a firm’s revenue is positive and convex in quality, and a few firms earn a large share of market revenue---are imperfect substitution between sellers, low marginal cost of output, and marginal cost declining as quality increases. Herein, a...

In an influential article, “Unraveling in Matching Markets,"Li and Rosen (1998) note that the first 7 picks, and 17 among 29 first-round selections, of the 1997 National Basketball Association (NBA) draft were not college seniors. By 2004, the first pick was a high school senior, and 25 of...

Akerlof (2012, 2013) has argued individuals often do not behave according to rational expectations. He shows how buyers in a complete lemon’s market are worse off if they behave irrationally---like loons. We examine several different lemon’s market situations (including when workers may...

More able individuals may over-investment in education when education signals ability. If education directly increases productivity, increasing education cost for the less able may increase welfare by reducing over-investment by the more able, but will not do so if such cost is already either...

The existing superstar model (Rosen, 1981) does not require imperfect substitutes, and the convexity of total earnings with respect to talent is due to greater output for those with more talent. Our model explains why wages would increase at an increasing rate in talent. Imperfect...

Maybe. Lemon’s and signaling models generally deal with different welfare problems, the former with withdrawal of high quality sellers, and the latter with socially wasteful signals. However, with asymmetric information, high productivity workers may not (absent signaling) be employed where...
