The present study aims to measure the technical efficiency and establish core factors affecting rice production in Cambodia. A four-year dataset generated from the central government document 'Profile on Economics and Social' of 25 entire provinces between 2012 and 2015 and the stochastic...

This paper considers the portfolio problem for high dimensional data when the dimension and size are both large.We analyze the traditional Markowitz mean-variance (MV) portfolio by large dimension matrix theory, and find the spectral distribution of the sample covariance is the main factor to...

Der vorliegende Beitrag diskutiert die optimale Organisation der Wasserversorgung unter Berücksichtigung der grundlegenden Gutscharakteristika und der spezifischen Produktions-struktur. Nach einer formalen Beschreibung der einzelnen Produktionsstufen und der realen Organisation des...

The provision of adequate infrastructure capital is crucial for the economic development and transition of rural areas in the former command economies of Central and Eastern Europe.

This discussion paper attempts the investigation of inefficiency with respect to water suppliers in rural areas of East and West Germany. This is done by using a nonradial measure of input-specific allocative inefficiency based on the demand system derived from a flexible cost function for the...

The availability of efficiency estimation software - freely distributed via the internet and relatively easy to use - recently inflated the number of corresponding applications. The resulting efficiency estimates are used without a critical assessment with respect to the literature on...

This paper aims to deliver empirical evidence on the links between production efficiency, biodiversity, and resource management by analysing a case study on small-scale tobacco production in the Miombo woodlands in Tanzania. The subsistence nature of tobacco production in Tanzania suggests that...

This paper focuses on smallholder maize production in Malawi by investigating the linkbetween productivity and soil fertility management. Many studies conducted in Malawi indicate declining levels of maize productivity thereby posing food security concerns, since maize is the staple crop for...
