The link between aggregate profits and investment has been widely analysed through the impact of profits on net worth and therefore the firm’s ability to borrow, in the presence of credit market imperfections. How the business cycle is affected if profits also affect investment through an...

Bayesian estimation is employed to investigate whether deep as opposed to superficial habit improves the fit of a dynamic stochastic general equilibrium model. If the stock of superficial habit features the additional persistence typical of deep habit, the two specifications are virtually as...

This paper contributes to an emerging literature that brings the constant elasticity of substitution (CES) specification of the production function into the analysis of business cycle fluctuations. Using US data, we estimate by Bayesian methods a medium-sized DSGE model with a CES rather than...

We investigate the time variation in the correlation between hours and technology shocks using a structural business cycle model. We propose an RBC model with a Constant Elasticity of Substitution (CES) production function that allows for capital- and labor-augmenting technology shocks. We...

We analyse the effects of a government spending expansion in a DSGE model with Mortensen-Pissarides labour market frictions, deep habits in private and public consumption, investment adjustment costs, a constant-elasticity-of-substitution (CES) production function, and adjustments in employment...

The response of hours to technology shocks is a key controversy in macroeconomics. We show that differences between RBC and NK models hinge on highly restrictive views of technology. We introduce CES production technologies and demonstrate that the response of hours depends on the...

We study the relationship between hours worked and technology during the postwar period in the US. We show that the responses of hours to technological improvements have increased over time, and that the patterns captured by the SVAR are consistent with those obtained from an RBC model with a...
