We extend the standard textbook search and matching model by introducing deep habits in consumption. The cyclical fluctuations of vacancies and unemployment in our model can replicate those observed in the US data, with labour market tightness being 20 times more volatile than consumption....

We estimate a New Keynesian model with matching frictions and nominal wage rigidities on UK data. We are able to identify important structural parameters, recover the unobservable shocks that have affected the UK economy since 1971 and study the transmission mechanism. With matching frictions,...

We investigate labor productivity dynamics amongst British businesses in the wake of the credit crisis of 2007/8. The external restructuring of firms (i.e. changes in market share, firm entry and exit) contributed to a fall in productivity growth relative to trend amongst small businesses in...

Shocks to investment-specific technology have been identified as a main source of U.S. aggregate output volatility. In this paper, we present a model with frictions in the labor market and explore the contribution of these shocks to the volatility of labor market variables, namely, unemployment,...

This thesis presents three papers in macro labor theory. All of them share the particular approach to the theory of unemployment pioneered by Dale Mortensen and Chris Pissarides. In these models unemployment is frictional, and emerges as an equilibrium outcome in an economy where workers and...

In Italy, following WWII, specific hiring procedures were developed that prevented firms from screening workers. More in particular, these institutions characterized the Italian labor market with respect to the US labor market, and were gradually removed during the 1990s. A simple matching model...

Employment has fallen during this recession but by much less than the fall in output. This article examines how the behaviour of the labour market compares with previous recessions. A number of factors, including greater flexibility in real wages, may have helped to mitigate the fall in...

We embed convex hiring and investment costs and their interaction in a New Keynesian DSGE model with Nash wage bargaining. We explore the implications with respect to inflation dynamics in the New Keynesian Phillips curve. We use two structural estimation methods (GMM and Bayesian estimation)...
