In a production economy with trade in financial markets motivated by the desire to share labor-income risk and to speculate, we show that speculation increases volatility of asset returns and investment growth, increases the equity risk premium, and reduces welfare. Regulatory measures, such as...

In this paper, we conduct an analysis of the implications of capital controls for financial stability. We study a financial transaction (Tobin) tax applicable to cross-border capital flows in a multi-good, multi-country dynamic equilibrium model with incomplete financial markets and...

This paper attempts to establish the existence of equilibrium, in an asset market inhabited by two representative investors with different risk aversions. In order to capture heterogeneity in information and wealth, the paper segments the investor population into two: (i) Individual investors...

In this paper, I study the impact of a global cap-and-trade system for greenhouse gas emissions on financial markets. The analysis is conducted using a general equilibrium production economy with two countries. One of the countries (developed country) introduces the system from the very...

In this paper, we conduct an analysis of the implications of capital controls for financial stability. We study a financial transaction (Tobin) tax applicable to cross-border capital flows in a multi-good, multi-country dynamic equilibrium model with incomplete financial markets and...

A dynamic pure-exchange general equilibrium model with uncertainty is studied. Fundamentals are supposed to depend continuously on states of nature. It is shown that: 1. if financial markets are complete, then asset prices vary continuously with states of nature, and; 2. if financial markets are...

We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different...
