A two-country dynamic general-equilibrium model with imperfect competition and price stickiness is considered. This work shows the conditions under which price stability can implement the flexible-price allocation as a Nash equilibrium. This is possible if and only if both countries maintain a...

This paper provides first and second-order approximation methods for the solution of non-linear dynamic stochastic models in which the exogenous state variables follow conditionally-linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

A positive and normative evaluation of alternative monetary policy regimes is addressed in a two-country general equilibrium model. The behaviour of the exchange rate, as well as of the other macroeconomic variables, depends crucially on the monetary regime chosen, though not necessarily on...

This Paper presents a two-country dynamic general equilibrium model with imperfect competition and nominal price rigidities in which terms of trade shocks coexist with inefficient supply shocks. We analyse the features of the optimal cooperative solution. While terms of trade shocks should be...

This paper revises the traditional view of Spain as a predatorycolonial state that extracted revenue from natural resources andpopulations in the Americas while offering little in return. Using 18thcentury Spanish American treasury accounts we show that localelites not only exerted important...

Hierarchies allow individuals to leverage their knowledge through others` time.This mechanism increases productivity and ampli…fies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings andorganization of U.S. lawyers and use an equilibrium...

Earnings inequality has increased substantially since the 1970s. Using evidence changes from con…dential Census data on U.S. law offices on lawyers'organization and earnings, we study the extent to which the mechanism suggested by Lucas (1978) and Rosen (1982), a scale of operations effect...
