The paper investigates the impact of subsidies and of para-agriculture on the technical efficiency of organic farms in Switzerland, Austria and Southern Germany. The data-set consists of bookkeeping data with 1,704 observations in the years 2003 to 2005. Technical efficiency is modelled using a...

This paper explores the consequences for parametric and non-parametric efficiency levels and rankings when using grouped instead of individual Decision Making Units (DMU). The bias results due to the differences of the grouped DMUs frontier compared to the individual DMUs frontier. Monte Carlo...

As the Argentinean grapevine production systems have gained global visibility, the wine industry has been revitalized with a greater focus on enological quality, technology adoption, and export orientation. Although grapevine production has decreased 36% in a decade nationwide, the province of...

The vast majority of the efficiency and productivity measurement literature has been based on the static viewpoint of the firm. Few studies have developed the dynamic analog of static efficiency measurement, introducing the notions of long-run efficiency and inefficiency persistence. However,...

Supermarkets are gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on productivity and efficiency have hardly been studied. We use a meta-frontier approach and combine this with propensity...

This work follows the series of studies conducted in Ipea, in order to compare the efficiency of the Brazilian health system to health systems of other countries. We evaluate the efficiency of expenditure in health care provision by comparing various output measures (life expectancy; infant...

This paper examines the productivity of hired and family labour and determinants of technical inefficiency of fish farms in Ghana. A modified Cobb-Douglas stochastic frontier production function which accounts for zero usage of family and hired labour is employed on cross-sectional data of 150...

This paper aims at assessing the health care services in the Brazilian state of Rio de Janeiro's municipalities. The evaluation is performed through the combination of non stochastics efficiency frontiers with regression models encompassing municipalities resources and outputs. The optimal...
