Efficiency measurement naturally requires the definition of a frontier as a benchmark indicating efficiency. Usually a measure reflecting the distance of a data point to the frontier indicates the level of efficiency. One of the crucial characteristics to distinguish efficiency measurement tools...

In this position paper we deal with the conception of heterogeneity as both the force and the result of evolutionary change. We ask, how this heterogeneity can be measured empirically and how we can get a measure which allows to get a broad comparable empirical account especially on several...

The objective of this paper is twofold. First we discuss, whether data envelopment analysis can be applied to households' consumption activities on the basis of Kelvin Lancaster's approach to consumer choice. Then, we apply data envelopment analysis to identify inefficiencies in a subsector of...

This paper reviews empirical and theoretical work concerning the relationship between innovative activities of firms and the dynamics of industries. Stylized facts on industry evolution and the analysis of industrial dynamics in general are a first building block. This discussion just reflects a...

The literature on firm heterogeneity in international trade posits that only the most productive firms become exporters (Melitz 2003). However, empirical findings suggest that also firms that are not highly productive export. This paper investigates empirically how firms organize their export...

[Zielsetzung / Abgrenzung] Die 'Schreckensherrschaft der EDV-Abteilung ist vorbei' - so der Titel eines Zeitungsartikels. Bereits vor einigen Jahren prophezeite Nicolas Carr 'the End of Corporate Computing'. Haben wir diesen Zeitpunkt inzwischen erreicht? Haben neue Technologien und...

Cross-border production networks have been playing an increasingly important role in the Association of Southeast Asian Nations (ASEAN) countries' trade in recent years, but micro-level studies are rare. This paper uses firm-level data from the two most active ASEAN countries in production...

This paper examines the role of international trade in employment growth in micro- and small enterprises using a representative sample of manufacturing firms in six Southeast Asian countries. After controlling for firm and individual characteristics as well as country and sector dummies,...

We apply various refinements of survival regression to assess the results of some basic specifications based on product life cycle theory for the case of a data set of the German automobile industry. The methods applied pay attention to biases in the coefficient estimates and the standard...

In this paper we document the results of a forecast evaluation exercise for the real world price of crude oil using VAR models estimated by sparse (regularization) estimators. These methods have the property to constrain single parameters to zero. We find that estimating VARs with three core...
