This paper studies a model of public policy with heterogenous citizens/voters and two public goods: One (roads) is chosen directly by an elected policymaker, and the other (pollution) depends stochastically on the amount of roads. Both a one-country and a two-country version of the model are...

A nudge is a paternalistic government intervention that attempts to improve choices by changing the framing of a decision problem. We propose a welfare- theoretic foundation for nudging similar in spirit to the classical revealed preference approach, by investigating a model where preferences...

Is an economy with adverse selection, moral hazard, or an incomplete set of risk markets "constrained" Pareto efficient? There are two sets of papers addressing this question, one asserting that, under seemingly quite general conditions, the economy is constrained Pareto efficient, the other (to...

The model of public policy studied in this paper has heterogeneous citizens/voters and two public goods: one (roads) chosen directly by an elected policy-maker, and the other (pollution) stochastically dependent on the amount of roads. Both a one-country and a two-country version of the model...

In a market with a safe rate and a risky asset that pays a continuous dividend stream depending on a latent state of the economy, several agents make consumption and investment decisions based on public information — prices and dividends — and private signals. We obtain the equilibrium in...

There are two sets of papers addressing this question, one asserting that, under seemingly quite general conditions, the economy is constrained Pareto efficient, the other (to...

A nudge is a non-coercive paternalistic intervention that attempts to improve choices by manipulating the framing of a decision problem. As any paternalism, it faces the difficulty of determining the appropriate welfare criterion. We propose a welfare-theoretic foundation for nudging similar in...

Interfirm relationships can be successful but are also fraught with problems. We study how to encourage one party, herein the seller, to make a cooperative relation-specific investment that will increase the joint surplus. The seller, fearing he will be held up by the buyer, typically refrains...

When a principal’s monitoring information is private (non-verifiable), the agent should be concerned that the principal could misrepresent the information to reduce the agent’s wage or collect a monetary penalty. Restoring credibility may lead to an extreme waste of resources - the so-called...
