We study dominant strategy mechanisms where the planner knows the distribution of types and the agents are instructed to announce their types to the planner. It is assumed that the planner has access to a technology of inspection which is costly but perfect, and that he can penalize an agent who...

Let there be a positive (exogenous) probability that, at each date, the human species will disappear. We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under this uncertainty, with expected-utility preferences. Various social welfare criteria entail alternative von...

"The market has both a coordination function and an incentive function. The first theorem of welfare economics is all about coordination; the principal-agent model is all about incentives. What is the relative importance of the market in carrying out these two functions? While there has been a...

Axiomatic bargaining theory (e.g., Nash's theorem) is static. We attempt to provide a dynamic justification for the theory. Suppose a Judge or Arbitrator must allocate utility in an (infinite) sequence of two-person problems; at each date, the Judge is presented with a utility possibility set in...

Microfoundations for a divide-and-conquer model of wage discrimination are provided by positing that workers' psychologies permit racial integration of firms to weaken workers' unity and hence reduce their bargaining power against employers. In this bargaining -- as opposed to competitive --...

For the first time in some years, a conservative government came to power in Denmark in 2001, due primarily to the citizenry's disaffection with social-democratic policies on immigration. We represent political competition in Denmark as taking place over two issues-the size of the public sector...

Contrary to the claim of Andrei Shleifer and Robert W. Vishny (1994), it is conceivable under market socialism to take firms out of the orbit of state control and that a less narrow theory of the state than theirs allows the possibility of democratic socialism mitigating problems of economic...

Why do both left and right political parties typically propose progressive income taxation schemes in political competition? Analysis of this problem has been hindered by the two-dimensionality space of admissible tax policies: Nash equilibria in pure strategies of the usual political game...
