We consider a two-candidate campaign competition in majoritarian systems with many voters. Some voters are loyal, some can be influenced by campaign spending. Own loyalty with respect to a candidate is the voter's private information. Candidates simultaneously choose their campaign budgets and...

This paper considers evolutionarily stable strategies (ESS) in a take-it-or-leave-it offer bargaining game with incomplete information. We find responders reject offers which yield a higher positive material payoff than their outside option. Proposers, in turn, make more attractive offers than...

A woman assessing the wealth of a potential husband may observe some, but not all, of his wealth. She may screen, leading to status consumption and wasteful gift giving. The screening activity is costly both for the potential husband, and for the woman, as it reduces the wealth of the man she...

We study the bilateral trade problem put forward by Myerson and Satterthwaite (1983) under the assumption that agents are loss-averse. We use the model developed by Kőszegi and Rabin (2006, 2007) to find optimal mechanisms for the minimal subsidy, revenue maximization and welfare maximization...

We analyze the optimal design of dynamic mechanisms in the absence of transfers. The designer uses future allocation decisions to elicit private information. Values evolve according to a two-state Markov chain. We solve for the optimal allocation rule, which permits a simple implementation....

We study platform design in online markets in which buying involves a (non-monetary) cost for consumers caused by privacy and security concerns. Firms decide whether to require registration at their website before consumers learn the price and all relevant product information. We show that a...

In this paper we propose a simple method of characterizing countervailing incentives in adverse selection problems. The key element in our characterization consists of analyzing properties of the full information problem. This allows solving the principal problem without using optimal control...

We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear utility. We formulate and characterize a basic underlying implementation duality. We show how this...

This theoretical paper explores the impact of gender diversity on team production. The key assumption is that men derive utility from signaling high ability to female colleagues. The analysis shows that some gender diversity maximizes expected team production if (i) men and women have similar...

This study examines whether higher information disclosure firms have higher associations with accounting returns (EPS) and stock prices based on the Ohlson (1995) model. Survey results on information disclosure and transparency of Taiwan firms in 2004 were obtained from the Taiwan SEC. The...
