This paper analyzes the link between the diffusion of information- and communication technology (ICT) and both the skill structure and employment expectations of the different skill categories. The analysis is based on cross-sectional data for 4150 German firms conducted in mid-2000. The...

We propose an estimation procedure for a semiparametric panel data censored regression model in which the error terms may be subject to general forms of nonstationarity. Specifically, we allow for heteroskedasticity over time and a time varying factor load on the individual specific effect....

Interaction effects capture the impact of one explanatory variable x 1 on the marginal effect of another explanatory variable x 2. To explore interaction effects, the so-called interaction terms x 1 x 2 are typically included in estimation specifications. While in linear models the effect of a...

Consumption patterns for chicken and eggs have changed since the outbreak of the H5N1 avian influenza (AI) throughout the world, but its potential impact on demand has not been thoroughly unveiled. Our study examines some important factors influencing behavioral changes and estimates their...

We study a random effects censored regression model in the context of repeated games. Introducing a feedback variable into the model leads to violation of the strict exogeneity assumption, thus rendering the random effects estimator inconsistent. Using the example of contributions to a public...

In this article we examine the potential effect of market structure on hospital technical efficiency as a measure of performance controlled by ownership and regulation. This study is relevant to provide an evaluation of the potential effects of recommended and initiated deregulation policies in...

While much of the literature on cross section dependence has focused mainly on estimation of the regression coefficients in the underlying model, estimation and inferences on the magnitude and strength of spill-overs and interactions has been largely ignored. At the same time, such inferences...
