Permutation tests on returns to scale and common production frontiers in nonparametric models
Rønn-Nielsen, Anders; Kronborg, Dorte; Asmild, Mette - 2022
Permutation techniques, where one recompute the test statistic over permutations of data, have a long history in statistics and have become increasingly useful as the availability of computational power has increased. Until now, no permutation tests for examining returns to scale assumptions,...

Exact tests on returns to scale and comparisons of production frontiers in nonparametric models
Rønn-Nielsen, Anders; Kronborg, Dorte; Asmild, Mette - 2019
When benchmarking production units by non-parametric methods like data envelopment analysis (DEA), an assumption has to be made about the returns to scale of the underlying technology. Moreover, it is often also relevant to compare the frontiers across samples of producers. Until now, no exact...

Productive efficiency analysis of quantitative economics journals through stochastic frontier analysis using panel data
Gavilan Ruiz, José Manuel; Ortega Irizo, Francisco Javier - In: Revista de métodos cuantitativos para la economía y … 30 (2020), pp. 297-311
The main goal of a scientific journal is to diffuse new knowledge. The number of citations received by a journal can be considered as a measure of this objective and, in turn, as a measure of productivity in relation to the production process in which the journals are involved. In order to...

Stochastic frontier analysis by means of maximum likelihood and the method of moments
Behr, Andreas; Tente, Sebastian - 2008
The stochastic frontier analysis (Aigner et al., 1977, Meeusen and van de Broeck, 1977) is widely used to estimate individual efficiency scores. The basic idea lies in the introduction of an additive error term consisting of a noise and an inefficiency term. Most often the assumption of a...

Cost efficiency and subsidization in German local public bus transit
Nieswand, Maria; Walter, Matthias - 2010
Subsidies are considered important means to facilitate the provision of public transit, yet the empirical evidence implies that they can have harming effects on costs and possibly also on operators' performance. This paper examines the impacts of deficit-balancing subsidies on the cost...

Estimating stochastic ray production frontiers
Tsionas, Efthymios G.; Izzeldin, Marwan; Henningsen, Arne; … - 2019
In this paper, we consider the stochastic ray production function that has been revived recently by Henningsen et al. (2017). We use a profit-maximizing framework to resolve endogeneity problems that are likely to arise, as in all distance functions, and we derive the system of equations after...
