This paper investigates a dynamic general equilibrium model with search. In particular, search externalities are reßected by an increasing returns to scale matching function, which may imply an indeterminate equilibrium. Hence, the model is capable to generate business ßuctuations, driven by...

In this note I discuss the condition for indeterminacy in the context of search models with increasing returns in the matching technology. Building on the theoretical framework set forth by Giammarioli (2003), I argue that increasing returns with respect to vacancies at the aggregate level is...

Qualitative mismatches arise when the qualifications or skills of workers, individually or in the aggregate, are different from the qualifications or skills required or specified for their jobs. This review provides an introduction to the subject as well as a survey for social scientists...

Using ‘search’ theory, technology adoption is conceived of as a critical factor in the aftermath of a technological shock, which increases employment in the leading sectors and total output in the economy. These implications are further investigated in the present paper, both formally and...

In this paper we offer a critical discussion about the concept of labour market rigidity in the light of recent theoretical approaches that have aimed to provide sound micro-foundations to the presence of unemployment in market economies. We point out that the concept of labour market rigidity...

In the traditional labor supply–demand approach, unemployment usually results from a lack of labor demand or excess of labor supply. However, in urban China, unemployment coexists with a conflicting phenomenon, shortage of workers in firms. In this study, we employ a novel approach to tackle...

In this study we develop and calibrate a search and matching model of the German labour market and analyze the impact of recent immigration. Our model has two production sectors (manufacturing and services), two skill groups and two ethnic groups of workers (natives and immigrants). Moreover, we...

In most OECD countries, unemployment benefits are tied to individual previous labor earnings. We study the progressivity of this indexation with regard to its effects on employment, output, and welfare in a calibrated general equilibrium model with search unemployment. Employment varies...
