We study the Beaudry and Portier (2006)-hypothesis of delayed-technology diffusion and newsdriven business cycles. For German data on TFP and stock prices we find qualitatively similar empirical evidence. Quantitatively, however, an impulse response analysis suggests that a substantial part of...

Separately, news and sunspot shocks have been shown empirically to be determinants of changes in expectations. This paper considers both of them together in a simple New Keynesian monetary business cycle model. A full set of rational expectations solutions is derived analytically. The analytical...

Can the standard search-and-matching labor market model replicate the business cycle fluctuations of the job finding rate and the unemployment rate? In the model, fluctuations are prominently driven by productivity shocks which are commonly interpreted as technology shocks. I estimate different...

This paper elaborates on the relative importance of sectoral shocks for real economic activity in Germany. Implications of multisectoral real business cycle models are examined by resorting to testing techniques based on stock market returns. The empirical evidence is obtained by calculating...

We estimate a seven-variable-VAR for the U.S. economy on postwar data using long-run restrictions, taking changes in long-run interest rates and inflation expectations into account. We find a strong connection between oil prices and long-run nominal interest rates which has lasted throughout the...

We find that real interest rates paid on government debt depend significantly upon current and expected future levels of debt, in Europe as in the US. But this result only emerges when we condition on foreign interest rates, illustrating financial international integration. The previously strong...

This paper addresses the question of whether and how easy monetary policy may lead to excesses in financial and real asset markets and ultimately result in financial dislocation. It presents evidence suggesting that periods when short-term interest rates have been persistently and significantly...

Several authors have proposed staggered wage bargaining as a way to introduce sticky wages into search and matching models while preserving individual rationality. I evaluate the quantitative implications of such an approach. I feed through a series of estimated shocks from US data into a search...

This paper outlines a simple regression-based method to decompose the variance of an aggregate time series into the variance of its components, which is then applied to measure the relative contributions of productivity, hours per worker, and employment to cyclical output growth across a panel...

With the widespread application of inventory control Systems in industry and trade and a fast growing Services sector the influence of inventory changes on the business sector should become less important over time. However, the empirical eyidence for Germany in the period 1970-1994 shows that...
