| This paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform... |

| The transition of East German agriculture led to major structural adjustments that showed some very particular phenomena. For instance, most of the successors of the former agricultural production cooperatives (LPGs) make slight losses and they operate at a higher employment level than new and re-established farms. In this paper we try to explain these phenomena with the farms' history prior to the transition period. Particular attention is given to sunk costs, the identity of members and employees, and old debts. A Data Envelopment Analysis of 210 financial statements distributed over the financial years 1992/93 to 1995/96 gives evidence that these historical arguments had a decisive impact on the farms' behaviour. However, this impact decreases over... |

| This article provides estimates of farm household efficiency and its determinants among smallholder farmers in Mozambique. A translog stochastic frontier production function and a first difference model incorporating a model of farm household inefficiency effects are applied to test the existence of agricultural farm household inefficiencies and their determinants in Mozambique. The null hypothesis of equal farm household efficiency among households was rejected. Variation in farm household efficiency indicates that access to agricultural technology is a severe constraint for most farm households. Factors such as access to advisory services, access to rural credit, membership to an agricultural association, use of improved agricultural technology... |

| Cattle feeding enterprises operate amid variability originating in prices and production. This research explicitly models yield risks related to cattle feeding by relating the mean and variance of yield performance factors to observable conditioning variables. The results demonstrate that pen characteristics, such as entry weight, gender, placement season, and location influence the mean and variability of yield factors, defined as dry matter feed conversion, average daily gain, mortality, and animal health costs. Ex ante profit distributions, conditional on cattle placement characteristics, are derived through simulation methods to evaluate the effects of price or yield shocks on the distributional characteristics of expected profits. |

| Recent trend depicts that tomatoes and tomatoes products rank 2nd most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2nd in the United States in terms of production value, generating $1.3 billion after head lettuce that contributed $1.4 billion in the same time period. In 2006, 422,000 acres of tomatoes were planted in the United States. Tomato is equally an important economic crop in the state of Georgia. In 2008, it ranked 14th in the Georgia vegetable acreage as 3,985 acres were planted. It also ranked 6th in terms of farm gate value in the same time period generating $51.2 million.

| Land quality and land degradation affect agricultural productivity, but quantifying these relationships has been difficult. Data are limited, and impacts are sensitive to the choices that farmers make. Summarizing new research by economists, soil scientists, and geographers, this report explores the extent to which land quality and land degradation affect agricultural productivity, how farmers' responses to land degradation are influenced by economic, environmental, and institutional factors, and whether land degradation poses a threat to productivity growth and food security. Results suggest that land degradation does not threaten food security at the global scale, but does pose problems in areas where soils are fragile, property rights are insecure, and... |
