While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is relatively little formal work on the transformation of individual judgments in group deliberation. I develop a model of judgment transformation and prove a baseline...

This paper uses panel data from the 16 main states in India during the period 1967- 1999 to study the effects of having higher female representation in the State Legislatures on public goods, policy and expenditure. I find that women legislators make different decisions than men legislators....

In response to recent work on the aggregation of individual judgments on logically connected propositions into collective judgments, it is often asked whether judgment aggregation is a special case of Arrowian preference aggregation.

We analyze the contracting structure in a moral hazard setting with several agents whereoutput is produced jointly and is the only contractible variable. Since the salary of each agentis a function of all agents efforts, a positive externality arises between them. This externalityis not...

We model the coordination of specialised tasks inside an organisation as quot;attribute matchingquot;. Using this method, we compare the performance of organisational forms (M-form and U-form) in implementing changes such as innovation and reform. In our framework, organisational forms affect...

Bewley's condition on production sets, imposed to ensure the existence of an equilibrium price density when L? is the commodity space, is weakened to allow applications to continuous-time problems, and especially to peak-load pricing when the users' utility and production function are Mackey...

This paper studies the design of law-making and law enforcement institutions based on the premise that law is inherently incomplete. Under incomplete law, law enforcement by courts may suffer from deterrence failure, defined as the social-welfare loss that results from the regime's inability to...
