This paper proposes a system of equations for modelling the volume of bilateral trade in multiple goods for a given set of countries. We postulate a gravity equation for each traded good rather than for the aggregate volume of bilateral trade. Special features of the system are the possibility...

During the last two decades, the labour demand structure in Germany and other OECD countries has experienced a decrease in the demand for low skilled and a rise in the demand for highly skilled employees. The adoption of modern technologies in the production process as well as the growth of...

This paper uses a structural approach to examine who matches with whom. A two-sided matching model that allows for marital sorting in response to marriage market flexibility and agents' preferences is utilized. Estimation is based on imbedding the numerical solution of a matching model within a...

This paper considers a panel duration model that has a proportional hazards specification with fixed effects. The paper shows how to estimate the baseline and integrated baseline hazard functions without assuming that they belong to known, finite dimensional families of functions. Existing...

This paper stresses the links that exist between concepts that are used in the theory of model reduction and concepts that arise in the missing data literature. This connection motivates the extension of the missing at random (MAR) and the missing completely at random (MCAR) concepts from a...

This paper is providing an initial empirical application of Lee and Pitt's approach to the problem of corner solutions with panel data. This approach deals with corner solutions in a manner consistent with behavioral theory. Furthermore it allows the use of flexible form cost functions and...

In this paper we analyze the importance of intertemporal non-separabilities for consumption decisions using household data. We follow the test suggested by Meghir and Weber (1996), so we exploit the variability of the within-period marginal rate of substitution (MRS) between commodities. We also...
