Measuring X-Efficiency and Scale Efficiency for a Sample of Agricultural Cooperatives

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Productivity and Efficiency Change for Agricultural Cooperatives in Japan: The Case of the Dairy-Farming Region in Hokkaido

The purpose of this paper is to analyze the productivity change for agricultural cooperatives in Japan measured by nonparametric output-oriented Malmquist indices of total factor productivity (TFP)┻ The productivity change is decomposed into technical change and technical efficiency change┻ Linear programming techniques are used to calculate the productivity change using a panel data set for 44...

Efficiency and Ownership: Evidence from Japanese Credit Cooperatives

Data envelopment analysis (DEA) is used to estimate the overall efficiency and productivity growth of credit cooperatives in Japan during 1992–1996. Overall efficiency is decomposed into output technical efficiency and input allocative efficiency. Twenty percent of all credit cooperatives in Japan are foreign owned with more than 90% of those owned by Koreans. The history of institutional discr...

Agribusiness and the Efficiency of Agricultural Policy

A common finding in agricultural policy analysis is that agricultural policies fail to achieve their main objective of farm income support efficiently. Here it is argued that this might be the case because beside the explicit goal of supporting farm income government also pursues the implicit policy objective of supporting agribusiness. In particular, it is shown for the Austrian bread grains m...
