Previous analyses have concluded that expectations of future excess stock returns rather than future real dividend growth or real interest rates are responsible for most of the volatility in stock prices. In this paper, we employ a state-space model to model the dynamics of the log...

Some observers have argued that the run-up in the Standard & Poor's 500 stock price index during the 1990s was due to irrational exuberance rather than market fundamentals. This article presents evidence that the case for market fundamentals is stronger than it appears on the surface. Nathan...

"We document the response of the individual components of the Producer Price Index (PPI) to commonly used measures of monetary shocks, and show that these responses are at variance with many widely-used macro models of monetary non-neutrality. Monetary shocks are shown to have large relative...

Oil price shocks are thought to have played a prominent role in U.S. economic activity. In this paper, we employ Bayesian methods with a dynamic stochastic general equilibrium model of world economic activity to identify the various sources of oil price shocks and economic fluctuation and to...

This paper integrates a financial accelerator mechanism à la Bernanke et al. (1999) and time-varying uncertainty into a medium-scale Dynamic New Keynesian model. In our model, uncertainty emerges from monetary policy (policy uncertainty) as well as from financial risks (micro uncertainty) and...

This paper integrates a financial accelerator mechanism à la Bernanke et al. (1999) and time-varying uncertainty into a Dynamic New Keynesian model. We examine the extent to which uncertainty and credit conditions interact with one another. The idea is that uncertainty aggravates the...
