We extend Armstrong’s result on exclusion in multi-dimensional screening models in two key ways, providing support for the view that this result holds true in a large class of models and is applicable to many different markets. First, we relax the strong technical assumptions he imposed on...

How important is financial development for economic development? A costly state veriÂ…cation model of financial intermediation is presented to address this question. The model is calibrated to match facts about the U.S. economy, such as the intermediation spreads and the firm-size...

An allocation rule is consistent if the recommendation it makes for each problem “agrees” with the recommendation it makes for each associated reduced problem, obtained by imagining some agents leaving with their assignments. Some authors have described the consistency principle as a...

We develop a general equilibrium model of residential choice and study the effects of two housing aid policies, public housing units and housing vouchers. Land is differentiated by both residential accessibility and local public goods, and the provision levels of local public goods are...

We identify previously unnoticed ways in which agents can strategically distort allocation rules, by affecting the set of “active” agents. (i) An agent withdraws with his endowment. (ii) He gives control of his endowment to someone else and withdraws. (iii) He invites someone in and let him...

This paper establishes existence of a stationary Markov perfect equilibrium in general stochastic games with noise a component of the state that is nonatomically distributed and not directly affected by the previous periods state and actions. Noise may be simply a payoff irrelevant public...

This paper assesses biases in policy predictions due to the lack of invariance of "structural" parameters in representative-agent models. We simulate data under various fiscal policy regimes from a heterogeneous-agents economy with incomplete asset markets and indivisible labor supply. Imperfect...

Individuals often lose confidence in their prospects as they approach the "moment of truth." An axiomatic model of such individuals is provided. The model adapts and extends (by relaxing the Independence axiom) Gul and Pesendorfer's model of temptation and self-control to capture an individual...

The Jones-Kierzkowski model of global fragmentation of production draws attention to the cost and efficiency of “service links” connecting “production blocks” in different countries. Country-specific service links include transport and telecommunications infrastructure and the overall...

We construct a family model of labor supply that features adjustment along both the intensive and extensive margin. Intensive margin adjustment is restricted to two values: full time work and part-time work. Using simulated data from the steady state of the calibrated model, we examine whether...
