This article is an idiosyncratic survey of the insider-outsider theory, describing the vision underlying the theory, and evaluating salient contributions to the literature in the light of this vision. We also indicate what appear to have been dead-ends and red herrings in past research. The...

Conventional wisdom suggests that nominal, demand-side shocks have only temporary effects on real macroeconomic magnitudes and that the duration of their effects depends on the degree of nominal inertia. It is also argued that, in the absence of unit roots, temporary supply-side shocks also have...

We introduce different skill groups and production functions into the Burdett-Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

Whereas the standard modern theories of unemployment were developed in the context of a single sector labour market, this paper presents a survey of how these theories can be integrated into a dual labour market setting. This approach dichotomises the labour market into two sectors, a primary...

This paper presents a search model with heterogeneous workers, social networks and endogenous search intensity. There are three job search channels available to the unemployed: costly formal applications and two costless informal channels - through family and professional networks. The gain from...

Working time accounts allow rms to smooth their demand for hours employed. Descriptive literature suggests that this reduces turnover and inhibits increase in unemployment during recessions. We model theoretically the optimal choice of hours by a rm with a working time account. We show that...

This paper introduces endogenous on-the-job training in the job creation and destruction model of the search and matching type by García-Pérez and Osuna (Dual labour markets and the tenure distribution: Reducing severance pay or introducing a single contract, 2014). The objective is to compare...

As part of a more general process of employment reallocation from less to more productive employers, job-to-job flows tend to be beneficial for productivity and for workers. Thus, when this rate slows, it is important to understand why. In the US, for example, the job-to-job flow rate is now at...

The trend towards labor market flexibility in Europe has typically involved introducing legislation that makes it easier for firms to issue temporary contracts with low firing costs, while not changing the level of protection that is in place for permanent jobs. This has created a strong...

The paper examines policy externalities between imperfectly competitive open economies where unemployment prevails in general equilibrium. We develop a two-country and two-sector model with monopolistic competition in the goods market and wage bargaining in the labor market. Policy externalities...
