We present an efficiency wage model in which workers' effort depends on the level and on the growth rate of their wage relative to an alternative wage. Using data for four countries (US, UK, FR, GY), the implications of the model are examined and are found to be in accordance with the...

We present a dynamic non-linear model for an efficient contracting between a firm facing adjustment costs on labour and a union having preferences which are subject to habit formation. The model’s first order necessary conditions are estimated for the French, the Dutch and the Belgian labour...

The effect of a firm's uncertainty regarding technological development on the formation of alliances is examined, and it is shown that this uncertainty is positively related to the number of alliances. However, higher uncertainty also makes the firm less likely to ally with others if the...

The costs of hiring a worker generally differ in size from the firing costs. This article investigates optimal labour demand schedules for production and nonproduction workers of firms that operate under uncertainty and face asymmetric costs of adjusting their workforce. In the empirical part...

This paper explores the aggregation problem and illustrates its relevance using data for the Netherlands from the third Community Innovation Survey (CIS3), and production and financial statistics. It compares the results of an innovation output equation that was estimated using data on...

The paper studies the degree of homogeneity of innovative behavior in order to determine empirically an industry classification of Dutch manufacturing that can be used for policy purposes. We use a two-limit tobit model with sample selection, which explains the decisions by business enterprises...

This paper studies the persistence of innovation and the dynamics of innovation output in Dutch manufacturing using firm data from three waves of the Community Innovation Surveys (CIS), pertaining to the periods 1994-1996, 1996-1998, and 1998-2000. We estimate by maximum likelihood a dynamic...

This paper proposes a method to implement maximum likelihood estimation of the dynamic panel data type 2 and 3 tobit models. The likelihood function involves a two-dimensional indefinite integral evaluated using two-step Gauss-Hermite quadrature. A Monte Carlo study shows that the quadrature...

This paper studies and assesses the impact of G3 Central Bank interventions on the DEM/USD exchange rate properties using daily realized moments of exchange rate returns (obtained from intraday data) for the period 1989-2001. Event studies in terms of the realized moments for the intervention...

This paper proposes a method to implement maximum likelihood estimation of the dynamic panel data type 2 and 3 tobit models. The likelihood function involves a two-dimensional indefinite integral evaluated using “two-step” Gauss-Hermite quadrature. A Monte Carlo study shows that the...
