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...

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

Adam Smith’s proposal for paying professors was intended to induce increased faculty knowledge. If students have imperfect information about what they learn, and universities can only imperfectly measure the input of faculty time in student learning, publications may be used to measure faculty...

Following Rosen [1981], superstar effects (earnings convex in quality and a few firms reaping a large share of market earnings) occur with imperfect substitution between sellers, low (and possibly declining) marginal cost of output, and marginal cost falling as quality increases. However,...

The existing superstar model (Rosen 1981) does not require imperfect substitutes and explains the convexity of total earnings with respect to talent due to higher output for those with the most talent. We develop a model that explains why per unit earnings (wages or prices) would increase at an...

It has been argued the draft may enable the military to attract more able individuals than a volunteer military and thus increase welfare. We find this may be the case if a volunteer military simply takes the least able individuals. Ignoring the deadweight loss from taxation, when the military...

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. A draft is more likely to increase human capital investment in the...

Oyer (2007, 2008) considered the turnover of economics professors early in their careers. He found professors are more likely to move down from higher ranked schools than up from lower ranked schools. An asymmetric information model suggests this phenomenon is explained by imperfect screening at...

Spence (1974a) considered a variant of his signaling model in which there are two types of jobs, and in which signaling can increase wealth by improving the allocation of individuals to jobs. Using results in signaling games since Spence’s work---the Riley outcome (Riley, 1979), the intuitive...
