Mikroökonomisch fundierte Einführung: Sie zeigt, wie man auch ohne Vorkenntnisse der Produktionsfunktion zu Aussagen über die produktive Effizienz kommen kann. Die Autoren stellen den Ansatz der nichtparametrischen Frontierfunktionsanalyse vor und erweitern ihn über verschiedene Schritte....

This paper investigates the sources of total factor productivity growth in the German manufacturing sector, 1981-1998. Decomposition formulae for aggregate productivity growth are used to identify the effects of structural change and entry-exit on aggregate productivity growth. Documented is a...

We investigate economic and institutional determinants of ICT infrastructure for a broad cross section ofmore than 100 countries. The ICT variable is constructed from a principal components analysis. The explanatory variables are selected by variants of the Lasso estimator from the machine...

Abstract The reduction of greenhouse gases is the key action to limit global warming. An important source of greenhouse gas emissions and pollution is the inefficiency of production processes. We report results from a stochastic nonparametric efficiency analysis using directional distance...

We use nonparametric methods to compute the environmental inefficiency of 100 countries over the period 1990-2017 on the macro-level. The inefficiency is expressed as the potential reduction of GHG emissions, holding economic output constant. Based on that, we estimate different trend functions...
