We introduce a model of an local public goods economy with a continuum of agents and jurisdictions with finite population. Under an especially mild condition of boundedness of per capita payoffs we show nonemptiness of the core of the economy. We then demonstrate that the equal treatment core...

We consider a new model of a local public goods economy with differentiated crowding in which we make a distinction between the tastes and crowding characteristics of agents. It is possible in this model to have taste-homogeneous jurisdictions that take advantage of the full array of positive...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply, by education, over the life cycle. The model provides an aggregation theory of individual labor supply, firmly grounded on micro evidence, and is used to study the aggregate...

There are substantial cross-country differences in labor supply late in the life cycle (age 50+). A theory of labor supply and retirement decisions is developed to quantitatively assess the role of social security, disability insurance, and taxation for understanding differences in labor supply...

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply over the life cycle, by education, both along the intensive and extensive margins. The model provides an aggregation theory of individual labor supply, firmly grounded on...

We construct and analyze a tractable search model of money with a non-degenerate distribution of money holdings. Analytical tractability comes from modeling decentralized exchange as directed search, which makes the monetary steady state block recursive. By adapting lattice-theoretic techniques,...

This paper develops a model to explain and analyze the evolution of network structure (connectivity)and design (flight frequency, aircraft size, prices) in the post-deregulation U.S. airline industry. We show that legacy carriers choice of Hub-and-Spoke networks and the emergence of low cost...

Dispersion of money balances among individuals is the basis for a range of policies but it has been abstracted from in monetary theory for tractability reasons. In this paper, we fill in this gap by constructing a tractable search model of money with a non-degenerate distribution of money...
