General financial models have become workhorse models in the fields of macroeconomics and finance. These models have been developed and extensively studied by general equilibrium theorists. What makes them so applicable for macroeconomics and finance is the well accepted fact that models with a...

We quantify the effect of financial leverage on stock return volatility in a dynamic general equilibrium economy with debt and equity claims. The effect of financial leverage is studied both at a market and a firm level where the firm is exposed to both idiosyncratic and market risk. In a...

This paper considers the generalized second-best analytics of optimal restructuring under a political constraint, building on the modeling approach in Dehejia (1997). It is shown that the second-best optimum entails administering the terms of trade shock fully at the initiation of the reform,...

In this paper we use a general equilibrium model of Vietnam, calibrated to 1995 data, to analyze tax reform options for Vietnam. We focus on aggregate welfare impacts as well as welfare of household groups ranked by income. The main focus is on indirect tax reform (VAT), but we also examine...

A three-good-two-primary-factor (3x2) general equilibrium model, along with parallel numerical illustrations, is developed to analyze the incidence and welfare cost of several taxes. The approach, blending theory and computed examples, enriches some well-known tax models and provides more...

Most economists’ instinctive reaction to price controls is that they are harmful. If enforced, they result in shortages and resource misallocation. With weak enforcement they often result in black markets, and high transaction costs. In this paper we assess the pros and cons of rice price...

We combine general equilibrium theory and théorie générale of stochastic processes to derive structural results about equilibrium state prices.

En este estudio analizamos el acuerdo comercial entre la Unión Europea (UE) y el Mercado Común del Sur (Mercosur), y predecimos sus efectos sobre el comercio y el bienestar utilizando un modelo de gravedad estructural de equilibrio general. En un primer paso, estimamos el incremento en los...
