This study applies a Super Efficiency Data Envelopment Analysis model to evaluate the efficiency of cars sold on the German market. Efficiency is conceptualized from a customers' perspective as a ratio of outputs that customers obtain from a product relative to inputs that customers have to...

The purpose of this study is to provide a broader, economic perspective on customer value management. By developing an efficiency-based concept of customer value we aim at contributing to the presently underrepresented research field of marketing economics. The customer value concept is utilized...

Zhang and Bartels (1998) show formallyhow DEA efficiency scores are affected by sample size. They demonstratethat comparing measures of structural inefficiency between samplesof different sizes leads to biased results. This note arguesthat this type of sample size bias has much wider...

This study investigates the measurement of the efficiency of product markets by means of Data Envelopment Analysis (DEA). To demonstrate how comparing average efficiencies derived by DEA across markets may lead to conclusions driven mainly by the effects of sample size when the samples differ...

This study introduces the concept of product performance from the perspective of customers. Product performance is measured as a ratio of outputs that customers obtain from a product relative to inputs that customers have to spend for purchasing and using the product. The output side is modelled...

This paper explores a selection of recently proposed bootstrapping techniques to estimate non-parametric convex (DEA) cost frontiers and efficiency scores for transit firms. Using a sample of Norwegian bus operators, the key results can be summarised as follows: (i) the bias implied by...
