This paper studies models where the correspondences (or functions) under consideration are never increasing (or weakly decreasing) in endogenous variables, and weakly increasing in exogenous parameters. Such models include games of strategic substitutes, and include cases where additionally,...

The paper provides a theory of interest rates determination in the informal credit market in backward agriculture highlighting the interactions between two informal sector lenders (a professional moneylender and a trader-interlocker) and explains the prevalence of different interest rates in the...

Governmental contracts may be renegotiated after political changes. Current governments can anticipate this and strategically distort contracts to influence renegotiation outcomes. In this sequential common agency game, the initial contract impacts elements of the renegotiation process: outside...

We examine a simple economic model of network formation where agents benefit from indirect relationships. We show that small-world features - -- short path lengths between nodes together with highly clustered link structures --- necessarily emerge for a wide set of parameters.

A repeated moral hazard setting in which the Principal privately observes the Agentfs output is studied. It is shown that there is no loss from restricting the analysis to contracts in which the Agent is supposed to exert effort every period, receives a constant efficiency wage and no feedback...

The economic cost of the U.S. health care system goes beyond the cost of prescription drugs, doctor office visits and surgical procedures/ medical image tests. The implicit part of the cost includes the global competitiveness that the U.S. loses being an industrialized economy. The high health...

In this paper we are interested in the social choice theory of allocating resources, which are available and can be consumed in integer units only. Since goods are available in integer units only, the social choice theory for such problems cannot exploit any smoothness property, which may...

In this paper we show that a feasible price allocation pair is a market equilibrium of a discrete market game if and only if it solves a linear programming problem. We use this result to obtain computable necessary and sufficient conditions for the existence of market equilibrium. We assume that...

This paper examines existence of Markov equilibria in the class of dynamic political games (DPGs). DPGs are dynamic games in which political institutions are endogenously determined each period. The process of change is both recursive and instrumental: the rules for political aggregation at date...

The trust building process is basic to social science. We investigate it in a laboratory setting using a novel multi-stage trust game where social gains are achieved if players trust each other in each stage. And in each stage, players have an opportunity to appropriate these gains or be...
