Problems of using grouped DMUs for efficiency measurement: Monte Carlo experiments, empirical dimension, and a correction procedure
Brümmer, Bernhard; Thiele, Holger D. - 1999
This paper explores the consequences for parametric and non-parametric efficiency levels and rankings when using grouped instead of individual Decision Making Units (DMU). The bias results due to the differences of the grouped DMUs frontier compared to the individual DMUs frontier. Monte Carlo...

Estimating poverty and inequality indicators using interval censored income data from the German microcensus
Walter, Paul; Weimer, Katja - 2018
Rising poverty and inequality increases the risk of social instability in countries all around the world. For measuring poverty and inequality there exists a variety of statistical indicators. Estimating these indicators is trivial as long as the income variable is measured on a metric scale....

Tender prices in local bus transport in Germany - an application of alternative regression techniques
Beck, Arne; Walter, Matthias - 2010
Competitive tendering of local bus services in Germany has received increased attention. Employing Seemingly Unrelated Regression analyses, we observe that prices have regionally varying determinants; for example, while prices throughout most of the federal state of Hesse increase over time,...

Do external technology acquisitions matter for innovative efficiency and productivity?
Gantumur, Tseveen; Stephan, Andreas - 2010
To quickly adapt to technological change and developments, and thus remain competitive, firms increasingly resort to the use of external technology. This paper investigates whether and to what extent the acquisition of external disembodied technology affects the efficiency and productivity in...

Ein nutzungskostenbasierter Ansatz zur Messung des Faktors Kapital in aggregierten Produktionsfunktionen
Knetsch, Thomas A. - 2012
Es wird eine Methode zur Messung des Produktionsfaktors Kapital vorgeschlagen, in der Vermögensarten nach ihrem Nutzungswert im Produktionsprozess gewichtet werden. Dazu werden Nutzungskosten für die einzelnen Anlageklassen mit Hilfe von Daten der Volkswirtschaftlichen Gesamtrechnungen sowie...

A user cost approach to capital measurement in aggregate production functions
Knetsch, Thomas A. - 2012
A method is proposed to measure capital services in production. This means that productive assets are weighted according to their user costs. The user costs of the individual asset classes are estimated based on data from the national accounts and other sources. The results show that, in the...
