We show how changes in the volatility of the real interest rate at which small open emerging economies borrow have an important effect on variables like output, consumption, investment, and hours. We start by documenting the strong evidence of time-varying volatility in the real interest rates...

The combination of a fixed exchange rate and downward nominal wage rigidity creates a real rigidity. In turn, this real rigidity makes the economy prone to involuntary unemployment during external crises. This paper presents a graphical analysis of alternative policy strategies aimed at...

We use more than a century of Argentine and Mexican data to estimate the structural parameters of a small-open-economy real-business-cycle model driven by nonstationary productivity shocks. We find that the RBC model does a poor job of explaining business cycles in emerging countries. We then...

This paper characterizes conditions under which interest-rate feedback rules that set the nominal interest rate as an increasing function of the inflation rate induce aggregate instability by generating multiple equilibria. It shows that these conditions depend not only on the monetary-fiscal...

Why did Finland experience, in 1991-1993, the deepest recession observed in an industrialized country since the 1930s? Using a dynamic general equilibrium model with labor frictions, we argue that the collapse of the Soviet-Finnish trade was a major contributor to the contraction. Finland's...

Financial crashes were followed by deep recessions in the Sudden Stops of emerging economies. An equilibrium business cycle model with a collateral constraint explains this phenomenon as a result of the amplification and asymmetry that the constraint induces in the responses of macro-aggregates...
