This paper develops a general equilibrium model to examine the quantitative effects of speculative bubbles on capital accumulation, growth, and welfare. A near-rational bubble component in the model equity price generates excess volatility in response to observed technology shocks. In...

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...

We explore the implications of shocks to expected future productivity in a setting with limited enforcement of financial contracts. As in Lorenzoni andWalentin (2007) optimal financial contracts under limited enforcement imply that to obtain external finance firms have to post collateral in...

We show that a model with imperfectly forecastable changes in future productivity and an occasionally binding collateral constraint can match a set of stylized facts about "sudden stop" events. "Good" news about future productivity raises leverage during times of expansion, increasing the...

We show that a business-cycle component of consumption growth (dubbed business-cycle consumption) with cycles between 2 and 4 years is effective in explaining the differences in risk premia across alternative test assets, including recently-proposed anomaly portfolios. We formalize the mapping...

Hou and Moskowitz (2005) use the stock price delay in reflecting market-wide information to measure market frictions each individual firm faces. In this study, to better understand how the price formation process is affected by the business cycle, we examine the relation between changes in the...
