We examine the plausibility of expectations-driven cyclical fluctuations in an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale in production. Due to a dominating wealth effect, our model is able to generate...

Recent cyclical episodes in the U.S. and G-7 economies are asymmetric: recoveries and expansions tend to be long and gradual and busts tend to be short and sharp. A large body of work views the two recent cyclical U.S. episodes, namely, the "new economy" boom in the late 1990s, and the 2000s...

Gali (1999) used a VAR with productivity and hours worked to argue that technology shocks are negatively correlated with labor and are unimportant for the business cycle. More recently, Beaudry and Portier (2003) studied a VAR in productivity and stock prices. Remarkably, they found that the...

While news shocks are believed to be instrumental in explaining business cycles, many existing models fail to predict an economic boom in consumption, investment, employment, output and the stock market in response to good news about future productivity. This paper proposes and evaluates a model...

We show that an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to future consumption demand. In sharp...

This note uses a dynamic stochastic general equilibrium model with direct preferences for financial wealth to explore how stock price booms and busts relate to the real side of the economy. It evaluates the 'speculative' (sunspots) and 'news' (anticipated future changes in productivity)...

We estimate a dynamic stochastic general equilibrium (DSGE) model with several frictions and both unanticipated and news shocks, using quarterly US data from 1954-2004 and Bayesian methods. We find that unanticipated shocks dominate news shocks in accounting for the unconditional variance of...

Recent studies proposed news about future technology growth as the main driver of macroeconomic fluctuations. The identification of these news through stock prices in SVARs has been criticized in the past. Therefore, I propose a series of experiments to test that hypothesis by examining its...

This paper reexamines the question of how to explain business cycle co-movements within and between countries. First, we present a simple flexible price models to illustrate how and why news shocks can generate robust positive co-movements in economic activity across countries. We also discuss...

The years leading up to the "great recession" were a time of rapid innovation in the financial industry. This period also saw a fall in interest rates, and a boom in liquidity that accompanied the boom in real activity, especially investment. In this paper we argue that these were not unrelated...
