Statistics are developed to test for the presence of an asymptotic discontinuity (or infinite density or peakedness) in a probability density at the median. The approach makes use of work by Knight (1998) on L_1 estimation asymptotics in conjunction with non-parametric kernel density estimation...

We study changes of the distribution of income, age, occupation, household size via their marginal and conditional densities. The data consists of cross sectional samples from the population of Brithish households drawn over the years of 1968 - 1995. Estimation is carried out nonparametrically...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a firm can costlessly receive external knowlegde best. Since knowledge spillovers are unmeasurable, a 'goodness of fit'...

This paper analyzes the relationship between investment in information and communication technologies (ICT), non-ICT-investment, labor productivity and workplace reorganization. Firms are assumed to reorganize workplaces if the productivity gains arising from workplace reorganization exceed the...

Most economic data are difficult to explore with the global window width kernel density estimator, because they require different amounts of smoothing in different locations. When data are right-skewed one possible approach to this problem is based on transformations of the data. We propose a...
