In this paper we consider the problem of aggregation of Hicks-Moorsteen productivity indexes. The aggregate indexes are derived in a manner which is justified by economic theory, consistent with previous aggregation results, and maintains analogous decompositions to the original measures. These...

In this paper we consider aggregate (group) Malmquist productivity index measures which allow inputs to be reallocated within the group (when in output orientation). This merges the single period aggregation results allowing input reallocation of Nesterenko and Zelenyuk (2007) with the aggregate...

Die Budgetierung ist seit langem ein, wenn nicht das zentrale Controllinginstrument. Jenseits der Budgetierung setzt demnach ein neues Controllingverständnis ein. Es mangelt nicht an Stimmen, die ein rasant gesteigertes Maß an Komplexität und Dynamik in der unternehmerischen Wirklichkeit...

In this paper we propose a very flexible estimator in the context of truncated regression that does not require parametric assumptions. To do this, we adapt the theory of local maximum likelihood estimation. We provide the asymptotic results and illustrate the performance of our estimator on...

In this paper we use the Kumar and Russell [American Economic Review (2002) Vol. 92, pp. 527–548] growth-accounting procedure to examine cross-country growth during the 1990s. Using a data set comprising developed, newly industrialized, developing and transitional economies, we decompose the...

The challenge of the econometric problem in production efficiency analysis is that the efficiency scores to be analyzed are unobserved. Statistical properties have recently been discovered for a type of estimator popular in the literature, known as data envelopment analysis (DEA). This opens up...

The discussion about the bias due to input (or output) aggregation in efficiency measurement based on data envelopment analysis, recently revisited by Tauer (2001) and Fare and Zelenyuk (2002) is continued. Attention is focused on the direction and the bounds of the aggregation bias.

In this article we generalize the aggregation theory in efficiency and productivity analysis by deriving solutions to the problem of aggregation of individual scale efficiency measures, primal and dual, into aggregate primal and dual scale efficiency measures of a group (e.g., industry). The new...
