Evaluating the Production and Price Impacts of Biotechnology Application in Crop Markets

Biotechnology crop traits have been applied on a widespread commercial global basis since 1996, making it the most rapidly adopted crop technology in agriculture. The primary biotechnologies used have included technology delivering herbicide tolerance and insect resistance for crops, such as corn, soybeans, cotton, and canola. This technology has provided farmers with productivity improvements through a combination of yield improvements and cost reductions. Thus, this technology has had an impact on prices of cereals and oilseeds (and their derivatives) both in countries where biotech traits were applied and in the global market. Realizing the surging significance of biotechnology application in global crop markets, this study first summarizes the productivity impacts of biotech crops on production; secondly, aims to quantify the impact of the use of biotech traits on production, utilization and prices of corn, soybeans, and canola as well as other crops where the biotechnology is not utilized.biotech crops, prices, yield, soybeans, corn, canola, partial-equilibrium model, price effects, Demand and Price Analysis, Productivity Analysis,

A Branching Time Model of CSP

I present a branching time model of CSP that is finer than all other models of CSP proposed thus far. It is obtained by taking a semantic equivalence from the linear time - branching time spectrum, namely divergence-preserving coupled similarity, and showing that it is a congruence for the operators of CSP. This equivalence belongs to the bisimulation family of semantic equivalences, in the sense that on transition systems without internal actions it coincides with strong bisimilarity. Nevertheless, enough of the equational laws of CSP remain to obtain a complete axiomatisation for closed, recursion-free terms.Comment: Dedicated to Bill Roscoe, on the occasion of his 60th birthda

Incorporating the voice of multiple customers into product design

Listening to the voice of the customer is made complicated when the roles of the customer are carried out by more than one individual or stakeholder (a stakeholder performs one or more of the decision-making roles normally enacted by a single customer). The issues surrounding multiple stakeholder requirements are examined with particular reference to small to medium enterprises (SMEs) and the rehabilitation industry; this industry is concerned with products that enable the elderly and disabled to live more independently. A series of case studies has been conducted to identify the current practices of rehabilitation companies and the suitability of accepted design methods for incorporating the voice of the customer into the design process. The results of the study indicate that smaller companies within the rehabilitation industry do not use formal methods of design or market research; this is partly attributable to their limited resources and experience. An outline is given of a method developed by the CACTUS Project to enable resource-limited companies in the rehabilitation industry to incorporate the voice of the customer into their design. The method is currently being tested. It is hoped that the CACTUS approach will be applicable to other industries with similar characteristics and multiple stakeholders

The Production and Price Impact of Biotech Crops

Biotech crops have now been grown commercially on a substantial global scale since 1996. This paper examines the production effects of the technology and impacts on cereal and oilseed markets through the use of agricultural commodity models. It analyses the impacts on global production, consumption, trade and prices in the soybean, canola and corn sectors. The analysis suggests that world prices of corn, soybeans and canola would probably be, respectively, 5.8%, 9.6% and 3.8% higher, on average, than 2007 baseline levels if this technology was no longer available to farmers. Prices of key derivatives of soybeans (meal and oil) would also be between 5% and 9% higher, with rapeseed meal and oil prices being about 4% higher than baseline levels. World prices of related cereals and oilseeds would also be expected to be higher by 3% to 4%. The effect of no longer using the current widely used biotech traits in the corn, soybean and canola sectors would probably impact negatively on both the global supply and utilization of these crops, their derivatives and related markets for grain and oilseeds. The modelling suggests that average global yields would fall for corn, soybeans and canola and despite some likely compensating additional plantings of these three crops, there would be a net fall in global production of the three crops of 14 million tonnes. Global trade and consumption of these crops/derivatives would also be expected to fall. The production and consumption of other grains such as wheat, barley and sorghum and oilseeds, notably sunflower, would also be affected. Overall, net production of grains and oilseeds (and derivatives) would fall by 17.7 million tonnes and global consumption would fall by 15.4 million tonnes. The cost of consumption would also increase by $20 billion (3.6%) relative to the total cost of consumption of the (higher) biotech-inclusive level of world consumption. The impacts identified in this analysis are, however, probably conservative, reflecting the limitations of the methodology used. In particular, the limited research conducted to date into the impact of the cost-reducing effect of biotechnology (notably in herbicide-tolerant soybeans) on prices suggests that the price effects identified in this paper represent only part of the total price impact of the technology
