This paper presents new empirical evidence on the cyclical behavior of US unemployment that poses a challenge to standard search and matching models. The correlation between cyclical unemployment and the cyclical component of labor productivity switched sign at the beginning of the Great...

Shimer (2005a) claims that the Mortensen-Pissarides search model of unemployment lacks an ampiflication mechanism because it cannot generate the observed business cycle fluctuations in unemployment given labor productivity shocks of plausible magnitude. This paper argues that part of the problem...

Average unemployment in Europe today is relatively high compared with OECD countries outside Europe. The majority of countries in Europe today have lower unemployment than any OECD country outside Europe, including the US. These two fa cts are consistent because the four largest countries in...

Theoretical predictions of the effect of TFP growth on employment are ambiguous, and depend on the extent to which new technology is embodied in new jobs. We estimate a model for employment, wages and investment with an annual panel for the United States, Japan and Europe and find that TFP...

Unemployment in Britain has fallen from high European-style levels to US levels. I argue that the key reasons are first the reform of monetary policy, in 1993 with the adoption of inflation targeting and in 1997 with the establishment of the independent Monetary Policy Committee, and second the...

This paper tests whether aggregate matching is consistent with unemployment being mainly due to search frictions or due to job queues. Using U.K. data and correcting for temporal aggregation bias, estimates of the random matching function are consistent with previous work in this field, but...

This article develops a model of unemployment fluctuations. The model keeps the architecture of the general-disequilibrium model of Barro and Grossman (1971) but takes a matching approach to the labor and product markets instead of a disequilibrium approach. On the product and labor markets,...

This paper is about the labour market consequences of creative destruction with on-the-job search. We consider a matching model in an economy with embodied technological progress and show that its dynamics are profoundly affected by allowing on-the-job search. We obtain that the elasticity of...

The Beveridge curve depicts a negative relationship between unemployed workers and job vacancies, a robust finding across countries. The position of the economy on the curve gives an idea as to the state of the labour market. The modern underlying theory is the search and matching model, with...

A central concern about immigration is the integration into the labour market, not only of the first generation, but also of subsequent generations. Little comparative work exists for Europe’s largest economies. France, Germany and the United Kingdom have all become, perhaps unwittingly,...
