We study minority representation in the workplace when employers engage in optimal sequential search and minorities convey noisier signals of ability than mainstream job candidates. The greater signal noise makes it harder for minorities to change employers' prior beliefs. When employers are selective, this leads to minority underrepresentation in the workplace. Diversity improves when the cost of interviewing, the average skill level of candidates, or the opportunity cost of not hiring increases. Reducing the cost of firing also increases minority representation. When employers are sufficiently unselective, the rigidity of employers' beliefs leads to overrepresentation of minorities.

Theory models of platform competition predict that prices and buyer-seller ratios should be approximately equal on coexisting auction sites. Using field experiments on eBay and Yahoo Auctions, we find evidence that is inconsistent with equilibrium hypotheses and suggest that the market is tipping. Prices on eBay are consistently 20-70 percent higher than those on Yahoo, and eBay attracts two additional buyers per seller. On Yahoo, prices and bidders counts are unaffected by the auction ending rule. Various differences between the sites cannot account for the magnitude of these disparities. However, a model of imitation dynamics can rationalize our findings. Adapted from the source document.

We study optimal contracting under imperfect commitment in a model with an uninformed principal and an informed agent. The principal can commit to pay the agent for his advice but retains decision‐making authority. Under an optimal contract, the principal should (i) never induce the agent to fully reveal what he knows—even though this is feasible—and (ii) never pay the agent for imprecise information. We compare optimal contracts under imperfect commitment to those under full commitment as well as to delegation schemes. We find that gains from contracting are greatest when the divergence in the preferences of the principal and the agent is moderate.

Many firms divide the price a consumer pays for a good into two pieces---the price for the item itself and the price for shipping and handling. With fully rational customers, the exact division between the two prices is irrelevant---only the total price matters. We test this hypothesis by selling matched pairs of CDs and Xbox games in a series of field experiments on eBay. In theory, the ending auction price should vary inversely with the shipping charge to leave the total price paid constant. Contrary to the theory, we find that charging a high shipping cost and starting the auction at a low opening price leads to higher numbers of bidders and higher revenues when the shipping charge is not excessive. We show that these results can be accounted for by boundedly rational bidding behavior such as loss-aversion with separate mental accounts for different attributes of the price or disregard for shipping costs.
