When there are peer effects in education, private schools have an incentive to vary tuition to attract relatively able students. Epple and Romano (1998) develop a general equilibrium model characterizing equilibrium pricing and student selection into schools when peer effects are present. The...

Do scale economies contribute to our understanding of international trade? Do international trade flows encode information about the extent of scale economies? To answer these questions we examine the large class of general equilibrium theories that imply Helpman-Krugman variants of the Vanek...

Traditionally, general-equilibrium models have taken effective property rights to be given and have been concerned only with analysing the allocation of resources among productive uses and the distribution of the resulting product. But, this formulation of the economic problem is incomplete...

We formalize the notion that GATT exceptions such as antidumping and escape clause actions can act as insurance for import competing sectors affected by adverse price shocks. We use a general equilibrium model with several import competing sectors and assume incomplete markets so that agents...

In an economy with imperfect labor contracts, differences in the distribution of human capital are an independent source of comparative advantage. I study a world economy with two sectors, one where output is produced by teams and another where individuals can work alone. When workers' abilities...

This paper formulates and estimates an open-economy overlapping generation general-equilibrium model of endogenous heterogeneous human capital in the form of schooling and on-the-job training. Physical capital accumulation is also analyzed. We use the model to explain rising wage inequality in...

We attempt to explain the overreaction of asset prices to movements in short-term interest rates, dividends, and asset supplies. The key element of our explanation is a margin constraint that traders face which limits their leverage to a fraction of the value of their assets. Traders may lever...

This paper assembles elements that are essential in forming an integral picture of the way a churning' economy functions and of the disruptions caused by transactional difficulties in labor and financial markets. We couch our analysis in a stochastic equilibrium model anchored with US evidence...

This paper employs MIMIC, an applied general equilibrium model of the Dutch economy, to explore various tax cuts aimed at combating unemployment and raising labor supply. MIMIC combines modern labor-market theories, a firm empirical foundation detailed description of Dutch labor-market...

The equity premium consists of a term premium reflecting the longer maturity of equity relative to short-term bills, and a risk premium reflecting the stochastic nature of equity payoffs and the deterministic nature of payoffs on reckless bills. This paper analyzes term premia and the risk...
