We apply a stochastic frontier production model to data from 53 countries during 1991-2003 to estimate total factor productivity growth, and decompose it into technical efficiency change and technical progress. Our empirical results indicate that world productivity growth was led by fast-growing...

We developed a technical efficiency analysis of container ports in Latin America and the Caribbean using an input-oriented stochastic frontier model. We employed a 10-year panel with data on container throughput, port terminal area, berth length, and number of available cranes in 63 ports. The...

This paper develops a port productivity and efficiency analysis of all developing regions between 2000 and 2010, using both parametric and nonparametric approaches. From a unique dataset -our sample covers 70 developing countries, 203 ports, and 1,750 data points-, we carry out an analysis of...

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...

Simar and Wilson (J. Econometrics, 2007) provided a statistical model that can rationalize two-stage estimation of technical efficiency in nonparametric settings. Two-stage estimation has been widely used, but requires a strong assumption: the second-stage environmental variables cannot affect...

Supermarkets and high-value exports are currently 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 farming efficiency have hardly been studied. Using a survey of Kenyan vegetable growers...
