Fortunes in the agricultural sectors of four of the largest South Pacific countries are traced in recent decades by estimating the single factoral terms of trade index. The single factoral terms of trade are measured for agriculture in four Melanesian countries-Fiji, Papua New Guinea, Solomon Islands and Vanuatu-over the period, 1970 to 2002. This index provides a useful method to assess changes in returns to factors employed in agricultural production in these countries. Except in Solomon Islands, farmers experienced a deteriorating index, indicating that they have reaped progressively lower returns to their resources. In Solomon Islands, returns to resources are shown to have increased slightly. A sustained contribution by the agricultural sector to... |

This paper examines the effects of farm characteristics and government policies in enhancing productivity growth for a sample of Greek farms, using a two-stage procedure. In the 1st-stage, non-parametric estimates of Malmquist index and its decompositions are computed, while a bootstrapping procedure is applied to provide their statistical precision. In the 2nd-stage, the productivity growth estimates are regressed on various covariates using a bootstrapped quantile regression approach. The effect that the covariates exert on productivity growth of the average producer is analyzed, as well as the marginal effect of a given covariate for individuals at different points in the conditional productivity distribution. The results indicate that there exists... |

This paper determined the optimal crop rotation in South Central Kansas. The model incorporated net return, risk, and water quality. In general, water quality improved as tillage was reduced within a rotation type and by adding an alfalfa rotation. The optimal crop rotation mixes included wheat, grain sorghum, soybeans, and alfalfa. |

We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 40 years, looking for evidence of recent changes in growth patterns using a nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture during between 1984 and 2003 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs, including an overall net reduction in fertilizer use but increased fertilizer use in most of the best-performing countries. Policy changes implemented by African countries between the mid-1980s and the second... |

En este trabajo se realiza un análisis comparado de dos métodos no paramétricos de medida de productividad total de los factores con datos de panel basados en programación: índices de Malmquist y un modelo DEA intertemporal que permite acotar las medidas de eficiencia y progreso técnico, suponiendo cambio técnico no regresivo. La aplicación se realiza sobre las agriculturas de los países de la Unión Europea, encontrándose algunas diferencias importantes entre ambos enfoques. Los resultados sugieren menor crecimiento de productividad agraria y, sobre todo, una ordenación distinta de países en relación con dichos crecimientos que los encontrados en otros trabajos. Palabras clave: Productividad, DEA, Agricultura, Europa, Datos de panel. SUMMARY This paper... |
