Two heterogeneous agents contribute over time to a joint project, and collectively decide its scope. A larger scope requires greater cumulative effort and delivers higher benefits upon completion. We show that the efficient agent prefers a smaller scope, and preferences are time-inconsistent: as...

Which budgetary institutions result in efficient provision of public goods? We analyze a model with two parties bargaining over the allocation to a public good each period. Parties place different values on the public good, and these values may change over time. We focus on budgetary...

We study learning via shared news. Each period agents receive the same quantity and quality of first-hand information and can share it with friends. Some friends (possibly few) share selectively, generating heterogeneous news diets across agents akin to echo chambers. Agents are aware of...

Do mandatory spending programs such as Medicare improve efficiency? We analyze a model with two parties allocating a fixed budget to a public good and private transfers each period over an infinite horizon. We compare two institutions that differ in whether public good spending is discretionary...

Tariff bindings and administered protection are two characteristics of the WTO that are little understood. Tariff bindings place a ceiling on tariffs that is not always reached, while administered protection ensures that all sectors have access to some minimum import protection, effectively...

We analyze major transitions in U.S. trade policy using a two-factor, two-good, two-country model, where domestic policy is the outcome of political bargaining between two parties representing each factor owner—globalists and protectionists. The dominant party sets the agenda, but parties must...

The institutions that have sustained global economic cooperation for the past 75 years are under threat. Despite admonitions that global peace and prosperity are at risk, policymakers in important countries have ignored the rules of the multilateral order and moved down the path of unilateralism...

We study bargaining between a fixed agenda-setter and responder over successive issues. If the responder rejects the setter’s proposal, the setter can attempt to assert her will to implement her ideal and will succeed with a probability that depends on her “personal power”. Players learn...

What prevents majorities from extracting surplus from minorities in legislatures? We study an infinite horizon game where a legislative body votes to determine distributive policy each period. Proposals accepted by a simple majority are implemented, otherwise the status quo allocation prevails....

When do voters win? In this paper we derive conditions under which a democracy will produce policies that favor the voter over special interests. We show that increasing political competition, increasing office holding benefits, decreasing potential rents to firms and increasing the salience of...
