This paper evaluates the global welfare impact of China's trade integration and technological change in a multi-country quantitative Ricardian-Heckscher-Ohlin model. We simulate two alternative growth scenarios: a "balanced" one in which China's productivity grows at the same rate in each...

We introduce the concept of a parameterized collection of games with side payments and determine a bound on e so that all sufficiently large games in such a collection have non-empty e -cores. A parameterized collection of games is described by (a) the number of approximate player types and the...

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...

The ``crowding types'' model of a local public goods economy makes a distinction between crowding effects and tastes of agents. Decentralization of the core is possible both with anonymous admission prices that depend only on publicly observable information and, when technology is linear, with...

We consider parameterized collections of games without side payments and determine a bound on epsilon so that all sufficiently large games in the collection have non-empty epsilon-cores. The required size of epsilon depends on: (a) the number of approximate player types and the accuracy of this...

We introduce the concept of a parameterized collection of games with limited side payments, ruling out large transfers of utility. Under the assumption that the payoff set of the grand coalition is convex, we show that a large game with limited side payments has a nonempty varepsilon core. Our...

This paper uses a database covering the universe of French firms for the period 1990- 2007 to provide a forensic account of the role of individual firms in generating aggregate fluctuations. We set up a simple multi-sector model of heterogeneous firms selling to multiple markets to motivate a...

This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi-sector model of the world economy calibrated to aggregate and firm-level data. Our framework features cross-country labor productivity differences, international trade, remittances, and a...
