| The agricultural production of Indian farmers is investigated using a stochastic frontier production function which incorporates a model for the technical inefficiency effects. Farm-level data from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) are used. Variables considered in the model for the inefficiency effects include the age and level of education of the farmers, farm size and the year of observation. The parameters of the stochastic frontier production function are estimated simultaneously with those involved in the model for the inefficiency effects. This approach differs from the usual practice of predicting farm-level inefficiency effects and then regressing these upon various factors in a second-stage of... |

| Smallholder farming systems in Papua New Guinea are characterised by an integrated set of cash cropping and subsistence food cropping activities. In the Highlands provinces, the subsistence food crop sub-system is dominated by sweet potato production. Coffee dominates the cash cropping sub-system, but a limited number of food crops are also grown for cash sale. The dynamics between sub-systems can influence the scope for complementarity between, and technical efficiency of, their operations, especially in light of the seasonality of demand for household labour and management inputs within the farming system. A crucial element of these dynamic processes is diversification into commercial agricultural production, which can influence factor productivity and... |

| This paper develops a new measure of total factor productivity growth in agricultural production which incorporates environmental effects. The new measure is called the Total Factor Nutrient-Orientated Productivity (TFNP) Index, and incorporates a materials balance condition. TFNP measures changes in nutrient-orientated efficiency and can be decomposed into efficiency change (EC), technological change (TC) and nutrient-orientated technological change (NTC) components. An empirical analysis, involving country-level data from OECD countries during 1990-2003, is provided using DEA methods. Estimates of mean technical and nutrient-orientated efficiency are 0.798 and 0.526, respectively. Estimated mean TFNP growth is 1.5% per year, with nutrient-orientated... |

| In this paper recent developments in the estimation of frontier functions and the measurement of efficiency are surveyed, and the potential applicability of these methods in agricultural economics is discussed. Frontier production, cost and profit functions are discussed, along with the construction of technical, allocative, scale and overall efficiency measures relative to these estimated frontiers. The two primary methods of frontier estimation, econometric and linear programming, are compared. A survey of recent applications of frontier methods in agriculture is also provided. |

| This paper analyses the determinants of foreign direct investment (FDI) in the manufacturing sector in Malaysia from eleven countries during the period 1988 to 2000. The empirical results indicate that gross domestic product, lending interest rate, labour productivity, exports to home country and imports from home country significantly influenced the level of FDI inflows into Malaysia. However, exchange rate, exchange rate variation, wage and openness index were not important in influencing FDI. |

| This paper fits a translog stochastic production frontier with inefficiency effects to a panel of 693 UK dairy farms for the period from 1982 to 1997. The Cobb Douglas is rejected as inadequate relative to the less restrictive translog functional form and the frontier model is statistically superior to the mean response function, despite the fact that on average the farms were 87% efficient. Technological progress, at 1.7% per annum, is the dominant force, but efficiency declined at 0.8% per year, which reduced productivity growth to 0.9% per annum. The inefficiencies are explained in the second stage of the model, where the greatest cause is financial exposure, captured here by the ratio of debts to assets. Older farmers, those in less favoured areas and... |

| During the 1950s and 1960s pipelines were built to provide water to many farms in the central wheatbelt of Western Australia using public funds. The resulting network has become known as the Comprehensive Water Supply Scheme. The expansion of the Scheme is currently under consideration. An ex ante cost benefit analysis of the proposed expansion is undertaken. An earlier analysis which focused on the benefits of the reduced necessity to cart water was rejected by farmer groups because of the inability of the analysis to properly account for domestic benefits and risk reduction. To overcome these criticisms a hedonic model of farm land values is formulated in which the independent variables are the characteristics of a property, including whether or not the... |
