This paper provides evidence for the impact of technology, labor supply, monetary policy and aggregate spending shocks on hours worked in the Euro area. The evidence is based on a vector autoregression identi?ed using sign restrictions that are consistent with both sticky price and real business...

This paper explores empirically the role of noisy information in cyclical developments and aims at separating fluctuations that are due to genuine changes in fundamentals from those due to temporary animal spirits or expectational errors (noise shocks). Exploiting the fact that the...

The reaction of hours worked to technology shocks represents a key controversy between RBC and New Keynesian explanations of the business cycle. It sparked a large empirical literature with contrasting results. We demonstrate that, with a more general and data coherent supply and production...

In this paper we test whether a reallocation of government budget items can enhance long-term GDP growth in a set of European countries. We apply modern panel data techniques to the period 1970-2006, and we use three alternative dependent variables in a growth regression: economic growth, total...

We study the aggregate implications of sectoral shocks in a multi-sector New Keynesian model featuring sectoral heterogeneity in price stickiness, sector size, and input-output linkages. We calibrate a 341 sector version of the model to the United States. Both theoretically and empirically,...

We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

Frequently, factors other than structural developments in technology and production effi- ciency drive changes in labor productivity in advanced and emerging market and developing economies (EMDEs). This paper uses a new method to extract technology shocks that ex- cludes these in uences,...

Frequently, factors other than structural developments in technology and production efficiency drive changes in labor productivity in advanced and emerging market and developing economies (EMDEs). This paper uses a new method to extract technology shocks that excludes these influences, resulting...
