The first part of this paper is devoted to describe a New Keynesian model, which, after calibration, shows a great fit on Euro area macroeconomic data. Then, the stabilizing properties of alternative monetary policy rules are evaluated for consideration of the European Central Bank (ECB). Our...

Revisions of US macroeconomic data are not white-noise. They are persistent, correlated with real-time data, and with high variability (around 80% of volatility observed in US real-time data). Their business cycle effects are examined in an estimated DSGE model extended with both real-time and...

Wage stickiness is incorporated to a New-Keynesian model with variable capital to drive endogenous unemployment uctuations de ned as the log di¤erence between aggregate labor supply and aggregate labor demand. We estimated such model using Bayesian econometric techniques and quarterly U.S....

This paper analyses the consequences of the existence of financial frictions and of a banking system on business cycles, in a new Keynesian macroeconomics model. We contrast our conclusions with those obtained in two other existing frameworks (namely the canonical nns model of Woodford, [2003]...

U.S. inflation has experienced a great moderation in the last two decades. This paper examines the factors behind this and other stylized facts, such as the weaker correlation ofinflation and nominal interest rate (Gibson paradox). Our findings point at lower exogenous variability of supply-side...

We describe a dynamic macroeconomic model that incorporates firm-level borrowing constraints, competitive CES loan production, and rigidities on both setting prices and wages. The external finance premium (interest-rate spread) is countercyclical with technology and financial shocks, and...

Employment fluctuations are examined, at different levels of aggregation, in a dynamic model that provides firm-specific hiring decisions due to search frictions and sticky pricing. The results indicate that firm-level employment dispersion rises with higher price stickiness and higher demand...

Wage stickiness is incorporated to a New-Keynesian model with variable capital to drive endogenous unemployment fluctuations defined as the log difference between aggregate labor supply and aggregate labor demand. We estimated such model using Bayesian econometric techniques and quarterly US...

This paper describes a DSGE model where the extensive margin of activity —the number of varieties available for consumption—, depends on micro-founded decisions of entry and exit in the goods market. Both the extended model and a more conventional version have been estimated with US data...

Entry rates have a negative long-run effect on US regional growth, which contradicts innovation-based growth models. This puzzle is resolved when a model-consistent specification is estimated using per capita entry growth. Evidence supports the Schumpeterian hypothesis of a positive relationship...
