The paper adds money supply and inflation expectations shocks to a well-known three-variable structural model that identifies oil price shocks through fundamentals affecting the oil market. Impulse responses show the significance of our two additional monetary shocks in impacting real oil...

Existing results on the contribution of terms of trade and world interest rate shocks to output fluctuations in small open economies range from less than 10% to almost 90%. We argue that an identification problems lies at the heart of these vastly different results. In this paper, we overcome...

We study the Beaudry and Portier (2006)-hypothesis of delayed-technology diffusion and news-driven 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...

This paper analyzes the impacts of news shocks on macroeconomic volatility. Whereas in any purely forward-looking model, such as the baseline New Keynesian model, anticipation amplifies volatility, we obtain ambiguous results when including a backward-looking component. In addition to these...

This paper examines the sources of fluctuations in inflation and output in two leading transitioneconomy candidates for admission to the European Union (EU), Poland and Hungary. Using a rational expectations, dynamic open economy aggregate supply- aggregate demand model, we consider real oil...

This paper develops a 9-dimensional SVAR to investigate the sources of the U.S. business cycle. We extend the standard set of identified shocks to include unexpected changes in commodity prices. Our main result is that commodity price shocks are a very important driving force of macroeconomic...

We explore empirically models of aggregate fluctuations with two basic ingredients: agents form anticipations about the future based on noisy sources of information and these anticipations affect spending and output in the short run. Our objective is to separate fluctuations due to actual...
