Nancy Cartwright views models as blueprints for nomological machines - machines which, if properly shielded, generate lawlike behaviour or regularities. Marcel Boumans has argued that we can look for devices inside models which enable us to measure aspects of these regularities. So, if models do...

In the period before the second World War, the Dutch Bureau of Statistics had developed two sets of indicators of unemployment in the Netherlands. One was based on statistical data of unemployment insurance funds of trade unions and the other one on statistical data of labour exchanges. This...

The purpose of this paper is to provide an analysis of the impact the Unemployment-Vacancy (UV) curve (or Beveridge curve) had on economic theory and to provide an account of the subsequent radical changes in its place and role over the decades since its first appearance in 1958. The paper...

This paper investigates two different procedures for the measurement of the NAIRU; one based on structural modeling while the other is a statisticai approach using Vector Auto Regression (VAR)-models. Both measurement procedures are assessed by confronting them with the dominant theory of...

This paper investigates i) the two measurement procedures of unemployment – one based on trade union unemployment insurance records and the other on labour exchange data – that were established by the Dutch official statistical office in order to measure the elusive concept of unemployment...
