Yes. We construct a measure of aggregate technology change, controlling for imperfect competition, varying utilization of capital and labor, and aggregation effects. On impact, when technology improves, input use falls sharply, and output may fall slightly. With a lag of several years, inputs...

What are the long-run aggregate effects of monetary shocks displaying throughthe credit channel of monetary policy? We address this question by investigatingthe transmission mechanism and estimating the dynamic behaviour of variablesrelated to credit and innovation. Then, we develop a DSGE model...

I study a dynamic stochastic general equilibrium model in which information on capital quality is asymmetric and the degree of information asymmetry varies endogenously with the state of the economy, amplifying the shocks. Firms hold capital and borrow to cover their operating expenses....

In the General Theory, Keynes remarked that the economy's state depends on expectations, and that these expectations can be subject to sudden swings. In this work, we develop a multiple equilibria behavioural business cycle model that can account for demand or supply collapses due to abrupt...

This paper explores the dynamic relationship between firm debt and real outcomes using data from 24 European economies over the period of 2000-2018. Based on macro data, it shows that a rise in credit to firms is associated with an increase in employment growth in the short-term, but employment...

This paper contributes to the GDP-consumption comovement puzzle literature investigating the role of tax evasion in explaining the consumption path after a Marginal Efficiency of Investment shock. We use an otherwise standard medium-scale New Keynesian DSGE model combining tax evasion with...

This paper contributes to the GDP-consumption co-movement puzzle literature investigating the role of tax evasion in explaining the consumption path after a Marginal Efficiency of Investment shock. We use an otherwise standard medium-scale New Keynesian DSGE model combining tax evasion with...

This paper examines the effects of labor-replacing capital, which we call robots, on business cycle dynamics using a New Keynesian model with a role for both traditional and robot capital. We find that shocks to the price of robots have effects on output, employment, wages, and labor's share of...

Hiring is a costly activity reflecting firms' investment in their workers. Microdata show that hiring costs involve production disruption. Thus, cyclical fluctuations in the value of output, induced by price frictions, have consequences for the optimal allocation of hiring activities. We outline...

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...
