This paper compares two different models in a common environment. The first model has liquidity constraints in that consumers save a single asset that they cannot sell short. The second model has debt constraints in that consumers cannot borrow so much that they would want to default, but is...

We characterize equilibria of general equilibrium models with externalities and taxes as solutions to optimization problems. This characterization is similar to Negishi's characterization of equilibria of economies without externalities or taxes as solutions to social planning problems. It is...

This paper develops a static neoclassical general equilibrium model of the Mexican economy that focuses on production, consumption, and exports of energy goods. The specificatin of the model allows the government to set prices and production levels of energy goods exogenously. Domestic prices...

We characterize the values of government debt and the debt's maturity structure under which financial crises brought on by a loss of confidence in the government can arise within a dynamic, stochastic general equilibrium model. We also characterize the optimal policy response of the government...

The use of general equilibrium models in applied research imposes a discipline in which model structures can easily be compared and contrasted and model results can be interpreted using a well understood and rigorously developed theoretical framework. These features allow researchers to compare...
