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...

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...

We study theoretically how the adjustment to liberalization of international financial transaction depends upon the degree of domestic financial development. Using a model with domestic and international borrowing constraints, we show that, when the domestic financial system is underdeveloped,...

We present a model that reproduces two salient facts characterizing the international monetary system: i) Faster growing countries are associated with lower net capital inflows and ii) Countries that grow faster accumulate more international reserves and receive more net private inflows. We...

We show that recent explanations of the consumption-real exchange rate anomaly which rely on goods and financial market frictions are not robust to introducing just one additional international asset. When portfolios are selected optimally, international trade in two nominal bonds implies a...

In this paper we study whether policy makers should wait to intervene until a financial crisis strikes or rather act in a preemptive manner. We study this question in a relatively simple dynamic stochastic general equilibrium model in which crises are endogenous events induced by the presence of...

In response to the global financial crisis a new policy paradigm emerged in which capital controls and other quantitative restrictions on credit flows have become part of the standard crisis prevention policy toolkit. A new strand of theoretical literature studies the use of capital controls in...

This paper presents a model of financial resource curse, i.e. episodes of abundant access to foreign capital coupled with weak productivity growth. We study a two-sector, tradable and non-tradable, small open economy. The tradable sector is the engine of growth, and productivity growth is...
