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...

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...

Traditionally, regulation of banks has focused on the riskentailed in bank loans. Loans are typically nontradedassets. In recent years, another component of bank assetshas become increasingly important: assets actively tradedin the financial markets.1 These assets form the “tradingbook” of a...

International financial integration has greatly increased the scope for changes in a country’s net foreign asset position through the “valuation channel” of external adjustment, namely capital gains and losses on the country’s external assets and liabilities. We examine this valuation...

This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher entry rates by prospective entrants subject to irreversible investment...
