In this paper I study a multi-task principal agent model with a risk-neutral principal and a risk neutral agent subject to limited liability in an environment with adverse selection and moral hazard. The main results are as follows: (1) the optimal contracts in each possible case is a bonus-type...

This paper studies the problem of self governance in a model in which information flows are governed by the community structure. In each round of an infinitely repeated game, an agent and an investor, who is selected from a finite set of investors, play a trust game. Investors receive...

We consider a two-period model of a banking system to explore the effects of competition on the stability and efficiency of economic activity. In the model, competing banks lend to entrepreneurs. After entrepreneurs receive the loans for their projects, there is a probability of a shock. The...

This paper studies which social networks maximize trust and cooperation when agreements are implicitly enforced. We study a repeated trust game in which trading opportunities arise exogenously and the social network determines the information transmission technology. We show that cohesive...

This expository paper describes the factors that contribute to failure of health insurance markets, and the regulatory mechanisms that have been and can be used to combat these failures. Standardized contracts and creditable coverage mandates are discussed, along with premium support, enrollment...

Using household surveys and bank penetration data at the district-level in 2006 and 2009, this paper examines the impact of Equity Bank—a leading private commercial bank focusing on microfinance—on the access to banking in Kenya. Unlike other commercial banks in Kenya, Equity Bank pursues...

This paper introduces an ordinal rational choice model for multiple kinds of social participation intensities to empirically investigate the relevance of several theoretical determinants of formation of Social Capital (SC) introduced in the literature. The framework is rich enough to investigate...

We study the consequences of bilateral market mergers. We first characterize the relationship between the M-optimal stable matching in the original markets with the M-optimal stable matching in the new market formed after the merger of the original markets. Then, we characterize the conditions...

This paper empirically examines whether the effect of financial openness on private credit depends on the market structure of the banking sector prior liberalization. We find that financial openness has a positive effect on private credit in countries characterized by a highly competitive...

We study repeated Bayesian n-player games in which the players' privately known types evolve according an irreducible Markov chain. Our main result shows that, with communication, any Pareto-efficient payoff vector above a stationary minmax value can be approximated arbitrarily closely in a...
