We study the effects of the more stringent employment protection legislation (EPL) that applies in Italy to firms with over 15 employees. We consider firms' propensity to grow when close to that threshold and changes in employment policies when they pass it. Using a comprehensive matched...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

This Paper introduces Heckscher-Ohlin trade features into a two-country DSGE model, and studies how productivity shocks propagate through trade in goods. In comparison with standard models, the business cycle properties of our framework are broadly compatible with the empirical evidence....

Does the search and matching model fit aggregate US labour market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some significant failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the...

Labour market regulations have often being blamed for high and persistent unemployment in Europe, but evidence on their impact remains mixed. More recently, attention has turned to the impact of product market regulations on employment growth. This Paper analyses how labour and product market...

This paper considers the ultimate causes of post-war UK business cycles. Using an extended stochastic growth model we construct estimates of a productivity and preference shock both of which are highly persistent, volatile and potentially capable of explaining UK business cycles. We find the...

This Paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The Paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the...

This Paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by US manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

We study a number of mechanisms through which an economy can be stuck at a high unemployment equilibrium because a poor labour market is associated with support for poor policy. These mechanisms are consistent with the relative scarcity of measures that have been undertaken to cure unemployment....

The model developed in this paper examines the relationship between firing costs and unemployment in a simple two-period model with uncertainty. Where there are long-term employment relationships, and where risk-averse workers and risk-neutral firms bargain over wages and firing costs, average...
