| 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... |

| Based on the co-integration test theory, Financial Interrelation Ratio (FIR), level of financial efficiency (LFE), level of financial development (LFD) and other indices evaluating the rural financial development are selected by Granger Causality Test. The rural loan balance (RLB), rural deposit balance (RDB), total rural output (TRO), fixed assets investment(FAI), Financial Interrelation Ratio (FIR), economic efficiency (EE), level of financial efficiency (LFE), and level of financial development (LFD) in the years 1979-2007 are collected. Graphical method intuitively reflects the development trend and historical track of relevant indices; and Granger Causality Test verifies the relationship between rural financial development level and rural economic... |

| This paper presents economic results of three groups of large farms, in the years 2000-2005, which were founded on the basis of the property of former state owned farms in Poland. They were divided according their legal and organisational form into: farms purchased, farms on lease and shareholder companies of the State Treasury. On the basis of the results of the analysis it was concluded that all three groups are economically effective, however, farms purchased, as a legal and organisational form, are protected against the production and market risk in the highest degree. Hence, the final direction of privatisation in Poland at the present stage of restructuring should be the purchase of farms. It does not mean, however, that there is a need to... |

| 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... |

| 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... |

| 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... |
