In this paper we assess the effects of the dramatic rise in agricultural commodity prices during 2007-2008 on income dynamics and poverty among rural households in Bangladesh. We use data from a nationally representative longitudinal survey of rural households in Bangladesh collected in four waves in 1988, 2000, 2004, and 2008. Nargis and Hossain (2006) analysed income dynamics and poverty incidence for the first three waves, finding a declining trend in both the incidence and depth of poverty, aided by in particular by human capital development and the off-farm labor opportunities. Here we update the analysis to include data collected in 2008, at the height of the aforementioned spike in agricultural prices. We find that various measures of rural poverty... |

This paper applies the gravity trade model to assess Mercosur-European Union trade, and trade potential following the agreements reached recently between both trade blocs. The model is tested for a sample of 20 countries, the four formal members of Mercosur plus Chile and the fifteen members of the European Union. A panel data analysis is used to disentangle the time invariant country-specific effects and to capture the relationships between the relevant variables over time. We find that the fixed effect model is to be preferred to the random effects gravity model. Furthermore, a number of variables, namely, infrastructure, income differences and exchange rates added to the standard gravity equation, are found to be important determinants of bilateral... |

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... |

Determining the competitive position of dairy farms depends on several technological, economic and institutional variables. Among them, are remarkable those related to animal feeding in the current context of high variability on prices. In this context, the aim of our study is to analyze the effects on milk supply and the competitiveness of dairy farms with different models of land intensification, with greater reliance on market purchases or self production of livestock feed. Our work is based on an econometric approach to a variable cost function, in a fixed effects model for unbalanced panel data of specialized dairy farms in Navarre (Spain). From this region, we use 3 geographical areas in relation to the availability of grazing land. It has been... |

A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low marginal contribution of labor inputs. The number of workers, size of farm, and distance from nearest city are related to efficiency in agricultural production. |

Farm-level, cross-section and panel data were used with econometric methods to examine relationships between variability in net farm income and explanatory variables including government payments, gross crop income, gross livestock income, costs, efficiency measures, and other socioeconomic characteristics such as age, leverage, percent of land rented, and enterprise diversification. The results suggest that quantifying the impacts of socioeconomic factors on variability of net farm income is difficult. Among the income variables, changes in gross crop income had the largest impact. Among cross-section data, increases in interest costs, age, and diversification were found to have positive relationships with net income variability. However, only the... |

The aim of this study is to analyse the evolution of the European regional agricultural productivity in terms of convergence. The initial hypothesis is that, in spite of the integration process, the agricultural productivity does not converge to the same stationary level. Additionally, we try to identify the decisive factors affecting such productivity growth. Productivity related information comes from Cambridge Econometrics database for a set of 125 EU-15 regions in the period 1985-2004. The methodology used consists in traditional beta convergence regressions. The difficulties with cross-sectional estimations require the use of panel data techniques for a better estimation of the speed of convergence. The main results show that convergence occurs to... |

We propose a detailed analysis of heterogeneity in households’ responses to water conservation programs (price increase, voluntary and mandatory conservation) during periods of water shortage. Using a unique dataset covering water consumption of all residential users in Los Angeles (California) during the drought (1988-1992), we show that households generally were responsive to the conservation measures but that the magnitude of households’ responses varies depending on the instrument and on households’ characteristics, in particular the size of their lot. Price elasticity is estimated between –0.29 and –0.47 in the high season (June-October), and between 0 and –0.19 in the low season (November-May). Results suggest that the voluntary conservation program... |

The objective of this paper is to analyze the Spanish demand for food taking into account the consumer's concern about the relationship between food diet and health. This concern is forcing food demand analysts to assume that consumer utility is a function of nutrients instead of simply the food products themselves. A CBS demand model has been considered to model the new demand function obtained, which is estimated with a complete panel data set. Ten broad categories, nine nutrients and the most relevant socio-economic variables have been considered. Finally, after an appropriate model selection strategy, expenditure, price and nutrient elasticities, as well as main sociodemographic effects, have been calculated. |

Little attention has been given in the agricultural economics literature to the impact of off-farm work on farm productivity and efficiency. More knowledge about what determines part-time farming and whether farm productivity and efficiency are affected by part-time farming could help policy makers introduce better targeted rural development policies. This paper aims to fill the above-mentioned gaps by first analysing factors that influence the choice of off-farm work; and then examining how off-farm work influences productivity and technical efficiency at the farm level. An unbalanced panel data set from 1991 to 2005 from Norwegian grain farms is used for this purpose. The results show that the likelihood of off-farm work and the share of time allocated... |
