Investment-specific technology shocks and international business cycles: an empirical assessment
In this paper, we first introduce investment-specific technology (IST) shocks into an otherwise standard international real business cycle model and show that a thoughtful calibration of them along the lines of Raffo (2009) successfully addresses several of the existing puzzles in the literature. In particular, we obtain a negative correlation of relative consumption and the terms of trade (Backus-Smith puzzle), as well as a more volatile real exchange rate, and cross-country output correlations that are higher than consumption correlations (price and quantity puzzles). Then we use data from ...

Inflation persistence: how much can we explain?
Until recently most macroeconomic models in which monetary policy has real effects were based on the assumption that agents in the economy do not use all available information when making a decision. Critics of these models argue that this assumption implies that agents are not rational. ; In response to this criticism, a class of New Keynesian models has recently been proposed. These models combine "old" Keynesian elements with an environment in which agents form their expectations rationally. The simplest version of such models includes only one type of nominal rigidity, either sticky ...

Nominal versus real wage rigidities: A Bayesian approach
This paper explores the capability of a dynamic stochastic general equilibrium model with staggered price setting and real wage rigidities to fit the data with reasonable average durations of price and wage contracts. The authors implement a Bayesian approach for parameter estimation and for model comparison with other models that only incorporate nominal rigidities. Their main results can be summarized as follows: First, the authors find that, on average, prices are fixed for three quarters, nominal wages are fixed for five quarters, and half of the wage setters follow a real wage indexing ...

Cointegrated TFP processes and international business cycles
A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are characterized by a vector error correction model (VECM) and that adding cointegrated technology shocks to the standard IRBC model helps explaining the observed high real exchange rate volatility. Also, we show that the observed increase of the real exchange rate volatility with respect to output in the past ...

Comparing New Keynesian models in the Euro area: a Bayesian approach
This paper estimates and compares four versions of the sticky price New Keynesian model for the Euro area, using a Bayesian approach as described in Rabanal and Rubio-Ramrez (2003). We find that the average duration of price contracts is between four and eight quarters, similar to the one estimated in the United States, while price indexation is found to be smaller. On the other hand, average duration of wage contracts is estimated to between one and two quarters, lower than the one found for the United States, while wage indexation is higher. Finally, the marginal likelihood indicates that ...
