We study the implications of having different sources of nominal rigidities on the relationship between productivity growth and shocks volatility in a model with procyclical R&D and imperfect competition in goods and labour markets. We show that the effects of uncertainty on long-term growth not...

This paper examines how the mechanism driving growth in the economy is likely to affect the optimal monetary policy response to shocks. We consider the Ramsey policy in a New Keynesian model in which growth is sustained by the creation of new patented technologies through R&D and we compare the...

This note presents an analysis which generalizes the results reached by Blackburn and Pelloni on the relationship between short-term stabilization policy and long-term growth by considering both deliberate (internal) and serendipitous (external) learning mechanisms for productivity growth

We consider a real business cycle model with a productive externality and an aggregate non-convex technology set a la Benhabib and Farmer embodying capacity utilization, which exhibits indeterminacy of the steady state and multiplicity of deterministic equilibria under plausible values of the...

A two-component model for the evolution of real GDP per capita in the USA is presented and tested. The first component of the GDP growth rate represents an economic trend and is inversely proportional to the attained level of real GDP per capita itself, with the nominator being constant through...

A defining feature of business cycles is the comovement of inputs at the sectoral level with aggregate activity. Standard models cannot account for this phenomenon. This paper develops and estimates a two-sector dynamic general equilibrium model which can account for this key regularity. My...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

Through a comparative dynamic analysis, we argue that the reality of public debt issuance, which responds flexibly to business cycles in contrast to the EU’s institutionally prescribed fiscal discipline, may contribute to macroeconomic stabilization. Through a simple econometric analysis, we...

Extended periods of ultra-easy monetary policy in advanced economies have rekindled debates about the zombification of weak companies and its impact on resource allocation, economic growth, inflation, and financial stability. Using both firm-level and macroeconomic data, we find that recessions...
