We seek to quantify and evaluate the supply (yield) response of wheat and cotton in Pakistan using cointegration analysis and annual data for 1960-96. The results reveal that wheat supply is significantly influenced by the prices of wheat, cotton and fertilizer, the percentage area under high yielding wheat varieties, and the rabi season (winter) water availability. The cotton supply is found to be significantly influenced by the real cotton price, the real fertilizer price, and the irrigated area. The wheat supply was found to be inelastic both in the short- and long-run. However, cotton supply was elastic in the long-run.

A non-linear optimization model which maximizes total Ecuadorian social welfare, defined as the sum of Consumers’ and producers’ surpluses for the four major crops (corn, bananas, rice and African palm) is developed to evaluate the tradeoff between welfare and environmental degradation in Ecuador. It was found that a total welfare loss of US$122 million (a 11 percent reduction - from US$ 1.112 billion to US$ 989.66 million) would be expected from a 30 percent reduction in the total pesticide load on the environment in the production of the four major crops. The distributional impacts of the welfare loss were found, however, to be significantly skewed toward the loss of consumers’ surplus. Specifically, a 30 percent reduction of total pesticide load on the environment would result in a reduction of 3.86 percent of producers’ total surplus while consumers would be expected to loose 19.46 percent of their total surplus.

As biotechnology evolves new methods of genetic engineering are now being applied to the production and processing of foods. This paper is trying to explore the attitudes of the European consumers towards genetic modification of food. Using survey data of the EU member countries the proposed research paper is planned to have a threefold output: 1) providing a comparative ranking of the EU member countries in relation to the prevalence of rejection of genetically modified food, 2) uncovering intra-european differences in genetic food engineering rejection as being based on socio-demographic and informational resp. knowledge based differentials between EU countries and 3) specifying the importance of socio-economic and informational determinants of a potential defender of genetically modified food by estimating the partial effects of age, gender, education, income, family status, size of household, knowledge on genetical food engineering and information use behavior in a multivariate model of the attitudes towards genetically modified food. This causal approach will be followed in selected EU countries representing extreme positions in the EU attitude ranking. By these empirical results the paper is trying to reveal intra-EU differentials of consumer attitudes towards genetically modified food, which is a necessary baseline for adequate and efficient policies in order to satisfy consumer needs for quality and security. The results will also prove helpful to the food industry providing differential information for marketing decisions and focusing adjustments in different EU food markets.

The aim of this paper is to identify optional ways of preventing NO3-levels from rising within Croatian farming systems, and the implications from the viewpoint of the manager. More specifically, the purpose is to

1) Determine whether Croatian farmers exceed profit maximising levels of N-fertiliser use in maize cultivation, and its possible influence on NO3-N-levels.

2) To estimate the marginal abatement cost (MAC), at the farm level, of reducing NO3-N leaching through the following instruments: a tax on optimal N-doses, a product tax and an N-fertiliser quota and a requirement for all instruments to correspond to the same abatement level.

Based on N-response experiment from feld trial for maize N-response curves were estimated. A sample of 20 family farms was used for calculating intensity, nutrient content in manure, and the prices paid for N and obtained for maize. Profit maximising doses from the field trials were compared with the use of nutrients on farms. An effluent production function was estimated based on experiments with NO3-N contents in lysimeter water for the same treatment levels as those in the N-response experiments. The results indicate that farmers use higher than optimal levels of N-fertilisers, if the manure is fully accounted for. In this case the estimated NO3-N/l level in groundwater is 162-192 % higher than the critical level stipulated by the Nitrate Directive. Neglecting the N-content in manure shows close to profit maximising nutrient levels . At this fertlising level the estimated NO3/l is approximately 62 mg NO3/l or clearly higher that the critical level stipulated by the nitrate directive (50 mg NO3/l). Through any of the three instruments a 76% NO3-leaching reduction could be obtained. It was concluded, however, that the quota has the lowest MAC (0.92 euro/mg NO3/l), followed by the N-fertiliser tax (3.65 euro/mg NO3/l), and the product tax comes in third place (9.32 euro/mg NO3/l). Management practices that may increase yield levels, and correspondingly NO3-leaching in the short and long run, were also identified. One way to achieve a quick improvement might be a system of cross compliance, stipulating a code of good agricultural practices.
