I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is endogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating new...

What are the implications of long-run productivity risk - shocks to the growth rate of productivity - for aggregate investment in a DSGE model? We offer an alternative to microfrictions explanation of aggregate investment non-linearities, in particular the heteroscedasticity of investment rate....
