Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are de fined using hypothetical models that assign variation to some of the inputs determining...

In this paper, location choices are driven by households (both blacks and whites) consciously choosing to trade off proximity to neighbors of similar racial backgrounds for proximity to jobs. Because of coordination failures in the location choices, multiple urban equilibria emerge. There is a...

In this paper fiscal policy is examined for an open economy characterised by unemployment due to efficiency wages. We allow for capital and firm mobility in a model where the government chooses the level of wage, source-based capital and profit taxation. The taxing choices of governments are...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We found that, depending on how...

We show that a stronger earnings relationship of unemployment compensation reduces wages and increases employment in an economy in which wages are determined by a trade union that maximises the rent from unionisation. The opposite result applies for a utilitarian union. Using manufacturing and...

Since the 1950s, there has been a steady decentralization of entry-level jobs towards the suburbs of American cities, while racial minorities ?and particularly blacks? have remained in city centers. In this context, the spatial mismatch hypothesis argues that because the residential locations of...

The aim of this paper is to provide a new mechanism for the spatial mismatch hypothesis. Spatial mismatch can here be the result of optimizing behavior on the part of the labor market participants. In particular, the unemployed can choose low amounts of search and long-term unemployment if they...

In order to alleviate unemployment it is often recommended to reduce social security contributions (SSC) and to compensate for the ensuing loss in revenues by a rise in the value-added tax (VAT). Assuming unemployment to be caused by efficiency wages, it is shown that a balanced-budget shift...

It is often argued that the quantity which is traded on the market is independent of the side of the market which is taxed. However, this assertion need not hold, especially in imperfectly competitive markets like that for labour. Taking an efficiency wage economy as an example, it is shown that...

In an efficiency wage economy with variable profits, a shift from payroll to employment taxes will reduce unemployment if the tax level is held constant at the initial wage. However, unemployment will rise if firms are constrained to zero profits in the long-run and if tax revenues are constant....
