In this paper we use mixed logit specifications to allow parameters to vary in the population when estimating the value of time for long-distance car travel. Our main conclusion is that the estimated value of time is very sensitive to how the model is specified: we find that it is significantly...

This paper investigates the power properties of the Sargan test in the presence of measurement errors in dynamic panel data models. The general conclusion from the Monte Carlo simulations is that the Sargan test, in many cases, leads the econometrician to accept misspecified models with...

The effectiveness of public funds in increasing public employment has long been a question on public and labor economists' minds. In most federal countries local governments employ large fractions of the working population, meaning that a tool for stimulating local public employment can...
