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...

We show in the framework of a new economic geography model that when labour is heterogenous and productivity depends on the quality of the match between job and worker, trade liberalization may lead to industrial agglomeration and inter-industry trade. The agglomeration force is the improvement...

This paper surveys recent work in equilibrium models of labor markets characterized by search and recruitment frictions and by the need to reallocate workers across productive activities. The duration of unemployment and jobs and wage determination are treated as endogenous outcomes of job...

Reduced-form tests of scale effects in markets with search, run when aggregate matching functions are estimated, may miss important scale effects at the micro level, because of the reactions of job searchers. A semi-structural model is developed and estimated on a British sample, testing for...

We explore the effects of taxes and subsidies on job creation, job destruction, employment and wages in the Mortensen-Pissarides version of the search and matching equilibrium framework. Qualitative analytical results show that wage and employment subsidies increase employment, especially of low...

We study a multi-sector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of structural change, characterized by sectoral labour reallocation, and constant aggregate growth path. The conditions are weak restrictions on the...

We survey the microfoundations, empirical evidence and estimation issues underlying the aggregate matching function. Several microeconomic matching mechanisms have been suggested in the literature with some successes but none is generally accepted as superior to all others. Instead, an aggregate...
