| Este estudo objetivou avaliar os custos de produção, receitas e rentabilidade da atividade leiteira de seis sistemas de produção de leite bovino no Cariri paraibano. Foi objetivo, também, identificar os componentes que exerceram maior influência sobre os custos finais da atividade por meio dos resultados econômicos e indicadores técnicos de desempenho econômico. Para a realização das análises econômicas, os produtores foram divididos em dois grupos, em função do vínculo com a Cooperativa, sendo sócios e não-sócios. A receita bruta da atividade foi suficiente para cobrir os custos operacionais efetivos e totais nas propriedades 1, 2, 3 e 5. Os itens que compõem o custo operacional efetivo de produção do leite foram responsáveis por porcentuais superiores a... |

| Seasonal growth of juvenile oysters (Crassostrea gigas) kept in an intensive upwelling system was studied from 1984 to 1986 in 60 to 90-day growth experiments. Saline ground water was used to produce Skeletonema costatum which was injected as food into the water supplying the upwelling system. Oyster density, water flow, phytoplankton concentration, temperature and frequency of food addition were controlled. Oyster growth was analysed with multidimensional contingency tables and correspondence analysis. The factors, in order of decreasing influence on growth, were temperature, food concentration and oyster density. A rearing strategy was deduced from the growth analysis for summer and winter. In summer, the density of 120,000 oysters/m2, the flow rate of... |

| After briefly reviewing recent economic theories about the economic welfare consequences of public provision of private commodities, this article examines the cost efficient supply of publicly provided commodities. In the light of the presence of transaction costs and bounded rationality, and consequences for the competence of public bodies, it considers whether the following are cost effective: (1) increased out-sourcing of government funded work and supplies using market and competitive mechanisms; (2) greater contestability of employment in the public sector; (3) more widespread imposition of user charges for publicly supplied commodities; and (4) the increased use of performance budgeting and accounting in the public sector. These measures are often... |

| Concern about sustainability helped to launch a new agenda for development and environmental economics and challenged many of the fundamental goals and assumptions of the conventional, neoclassical economics of growth and development. We review 25 years' of refereed journal articles on the economics of sustainability, with emphasis on analyses that involve concern for intergenerational equity in the long-term decision-making of a society; recognition of the role of finite environmental resources in long-term decision-making; and recognizable, if perhaps unconventional, use of economic concepts, such as instantaneous utility, cost, or intertemporal welfare. Taken as a whole, the articles reviewed here indicate that several areas must be addressed in future... |

| This study estimates the technical, allocative and economic efficiency obtained from the Data Envelopment Analysis (DEA) approach using farm level survey data to a sample of 100 poultry farmers in Bangladesh for the year 2007. The results from the DEA approach show that there is substantial technical, allocative and economic inefficiency in poultry production in Bangladesh. The results of the study reveal that under constant return to scale (CRS) and variable returns to scale (VRS) specification, on average, the farms technical, allocative and economic efficiencies were 88%, 70%, 62% and 89%, 73%, 66% respectively. Thus the results indicate that efficiency scores vary substantially across the sampled farms. To explain some of these variations, the... |

| Despite the fact that land rental is restricted to varying degrees in India, the participation in this market is widespread and it is observed to operate relatively efficiently in 12 villages studied in Andhra Pradesh and Madhya Pradesh. The estimated probit models predicted that the rental market transferred land to those with relatively smaller holdings, but greater ability to make productive use of land, more assets to invest, more adults available for labour and fewer off-farm opportunities. Also land is rented out predominantly to younger farmers and to farmers not involved in off-farm jobs. Renting in is predicted to be relatively higher in the villages which are remote and weakly integrated into mainstream infrastructure and institutions. Land... |
