We develop a heterogeneous-agent New Keynesian model featuring a frictional labor market with on-the-job search to quantitatively study the positive and normative implications of employer-to-employer (EE) transitions for inflation. We find that EE dynamics played an important role in shaping the...

This paper analyses how labour market heterogeneity affects unemployment, productivity and business cycle dynamics that are relevant for monetary policy. The model matches remarkably well the short and long run dynamics of skilled and unskilled workers. Skill mismatch and skill-specific labour...

A widely spread belief among economists is that monetary policy has relatively short-lived effects on real variables such as unemployment. Previous studies indicate that monetary policy affects the output gap only at business cycle frequencies, but the effects on unemployment may well be more...

This paper explores the role that the imperfect knowledge of the structure of the economy plays in the uncertainty surrounding the effects of rule-based monetary policy on unemployment dynamics in the euro area and the US. We employ a Bayesian model averaging procedure on a wide range of models...

In the standard New Keynesian sticky price model the central bank faces no contradiction between the stabilization of inflation and the stabilization of the welfare relevant output gap after a productivity shock hits the economy. When the standard model is enhanced by real wage rigidities or...

This dissertation consists of five distinct empirical papers covering two large areas of research that are rather independent from each other: the economics of ageing and the economics of innovation. The first three chapters cover the impact of intergeneration interaction on the parents of adult...

On average, small business support projects appear to improve beneficiary sales, and the growth effect is obvious when supporting young or growing firms. However, the effect is largely offset by sales reductions due to overcrowding. Small business support projects must be operated in two ways to...
