This paper shows that the Bennet-Bowley profit indicator is an exact and superlative approximation of the additively complete Luenberger-Hicks-Moorsteen productivity indicator when the input and output directional distance functions can be represented up to the second order by a quadratic...

In this paper method and practice of cross-efficiency calculation is discussed. The main methods proposed in the literature are tested not on a set of artificial data but on a realistic sample of input-output data of European warehouses. The empirical results show the limited role which...

This chapter covers the theory and methods for productivity measurement for nations. Labor, multifactor and total factor productivity measures are defined and are related to each other and to gross domestic product (GDP) per capita. Their growth over time and relative counterparts are defined as...

We introduce an ordinal model of efficiency measurement. Our primitive is a notion of e ciency that is comparative, but not cardinal or absolute. In this framework, we postulate axioms that we believe an ordinal efficiency measure should satisfy. Primary among these are choice consistency and...

Im Alltag verbrauchen Automobile deutlich mehr Kraftstoff, als sie nach den Angaben der Autobauer verbrauchen sollten. Die Herstellerangaben sind das Ergebnis eines Tests, den die EU zur Zulassung, zum Verkauf und zur Inbetriebnahme von Neufahrzeugen zwingend vorschreibt. Ferdinand Dudenhöffer,...

The shipping crisis starting in 2008 was characterized by sharply decreasing freight rates and sharply increasing financing costs. We analyze the dependence structure of these two risk factors employing a conditional copula model. As conditioning factors we use the supply and demand of seaborne...

The process of globalization is an international economic order which has led to the progressive integration of the world economy through the pulling the barrier of trade and greater mobility of factors of production. In addition the technological innovation also provides impetus to the...

This paper provides a comparative analysis of statistical methods to evaluate the consumer perception about the quality of Services of General Interest. The evaluation of the service quality perceived by users is usually based on Customer Satisfaction Survey data and an ex-post evaluation is...

This paper derives formulas for additive "chained volume measures" (CVMs) of GDP subaggregates depending on the underlying GDP quantity index. In turn, this paper explains why the formulas used in current practice yield nonadditive CVMs. This paper's additive formulas have significant practical...
