Última AGRICULTURAL BIOTECHNOLOGY: FARM-LEVEL, MARKET, AND POLICY CONSIDERATIONS AgEcon Van der Sluis, Evert; Diersen, Matthew A.; Dobbs, Thomas L.. This study provides an overview of the economic costs, benefits, and risks involved with agricultural biotechnology at the farm level, at the market level, and for the farm and food system as a whole. Both advantages and disadvantages of agricultural biotechnology are discussed. Among the drivers of U.S. domestic and international consumer demand for transgenic crop products discussed are environmental and food safety concerns. A comparison is made between a "science-based" regulatory framework and a policy based on the precautionary principle. The authors argue that open dialogue is needed for achieving improved public understanding of agricultural biotechnology, and that analyses need to go beyond discussing the scientific merits of biotechnology, to...

Ano: 2002 URL: http://www.infoteca.cnptia.embrapa.br/infoteca/handle/doc/499942 ECONOMIC EFFECTS OF PURITY STANDARDS IN BIOTECH LABELING LAWS AgEcon Giannakas, Konstantinos; Kalaitzandonakes, Nicholas G.. This paper develops a model of heterogeneous consumer preferences to analyze the market and welfare effects of reduced purity standards for non-GM labeled food. Analytical results show that purity standards affect the equilibrium prices and quantities of both the GM and non-GM products as well as the welfare of the groups involved. A change in purity standards is shown to create winners and losers among the consumers as well as among the suppliers of the GM and conventional products.

Ano: 2005 URL: http://purl.umn.edu/19393 Endogenous R&D Investment and Market Structure: A Case Study of the Agricultural Biotechnology Industry AgEcon Anderson, Benjamin; Sheldon, Ian M.. Over the past three decades, the agricultural biotechnology sector has been characterized by rapid innovation, market consolidation, and a more exhaustive definition of property rights. The industry attributes consistently identified by the literature and important to this analysis include: (i) endogenous sunk costs in the form of expenditures on R&D; (ii) seed and agricultural chemical technologies that potentially act as complements within firms and substitutes across firms; and (iii) property rights governing plant and seed varieties that have become more clearly defined since the 1970s. This paper adds to the stylized facts of the agricultural biotechnology industry to include the ability of firms to license technology, a phenomenon observed only...

Ano: 2011 URL: http://purl.umn.edu/107832 Genetically Modified Crops and Labor Savings in US Crop Production AgEcon Gardner, Justin G.; Nelson, Carl H.. In spite of widespread adoption there is mixed evidence as to whether or not adopting Genetically Modified (GM) crops increase farm welfare. One possible reason for widespread adoption is labor savings. Using a treatment effect model we estimate the labor savings associated with adopting a GM crop.

Ano: 2007 URL: http://purl.umn.edu/34919 GM-free private standards and their effects on biosafety decision-making in developing countries AgEcon Gruere, Guillaume P.; Sengupta, Debdatta. We provide a comprehensive review of international cases where GM-free private standards set up by food companies in developed countries have influenced biosafety policymaking in developing countries. We find twenty-nine cases where private importers have directly or indirectly affected policy decisions in twenty-one countries. Most of the cases relate irrational fear of export losses to excessively precautionary decisions. These cases are based on two generally misleading premises: the belief that Europe or Japan represents the only market for exports, and the perception that non-GM segregation is infeasible or prohibitively costly in all situations. Our study also demonstrates the importance of information asymmetries across countries and agents and the...

Ano: 2009 URL: http://purl.umn.edu/51334 Knowledge Capital, Intangible Assets, and Leverage: Evidence from U.S. Agricultural Biotechnology Firms AgEcon Sporleder, Thomas L.; Moss, Leeann E.. Agricultural biotechnology firms are high technology companies. Firms in general, and high technology firms in particular, are a set of both assets in place and growth opportunities. This has important implications for managerial decision-making. Knowledge capital motivates exploitation of growth options, which affects firm cash flow. In turn, the level and volatility of firm cash flow influences firm financing decisions. Previous studies suggest that knowledge capital can influence both the location and capital structure of firms in the biotechnology industry. However, empirical analysis has not extended to agricultural biotechnology firms. This research helps in understanding the role of knowledge capital and other intangible assets in capital structure...

Ano: 2004 URL: http://purl.umn.edu/8123 Managing agricultural biotechnology in Colombia Electron. J. Biotechnol. Schuler,Ingrid; Orozco,Luis Antonio. The international scenario for biotechnology shows a rapid tendency at industrialized countries in the increase of publications, patents, enterprises and novel solutions for the industry, the environment, health and agriculture. Nevertheless, Colombia has an important delay in relation to the international scientific development and the capacity to generate wealth and services for its productive systems. This delay has been one of the concerns of the country's policy during the last years, and more precisely since 2002, when for the first time biotechnology was included in a National Development Plan as one of the mechanisms for competitiveness and the use of biodiversity and genetic resources. This paper is the result of a survey conducted in 2005 aimed... Tipo: Journal article Palavras-chave: Agricultural biotechnology; Indicators; Legislation; Policies; Public perception..

In this paper we use content analysis to show trend in public opinion of agrobiotechnology in the United Kingdom (UK) and the United States (US). We test for the degree of positive and negative content in mass media reporting over the period 1995-1998. Specifically, we test whether there are qualitative and quantitative differences between three national daily newspapers - the Daily Telegraph (UK), USA Today (US), and the Washington Post (US) - based on reporting of agrobiotechnology. Results indicate that content has become more negative in the UK over the time period while reporting the US has not significantly changed. Results indicate that both the BSE and Pusztai crises had an impact on the proportion of negative reporting in the Daily Telegraph.

Ano: 1999 URL: http://purl.umn.edu/21678 PUBLIC-PRIVATE PARTNERSHIPS IN AGRICULTURAL RESEARCH: AN ANALYSIS OF CHALLENGES FACING INDUSTRY AND THE CONSULTATIVE GROUP ON INTERNATIONAL AGRICULTURAL RESEARCH AgEcon Spielman, David J.; von Grebmer, Klaus. Public-private partnerships offer potentially important opportunities for pro-poor agricultural research in developing countries. Yet in the international agricultural research community--and with regard to the Consultative Group on International Agricultural Research (CGIAR) itself--we see few examples of successful public-private partnerships, and fewer examples where such collaborations have contributed to food security, poverty reduction and economic growth. This study assesses the opportunities for, and challenges to, creating and sustaining public-private partnerships between the international agricultural research centers of the CGIAR and leading multinational, research-based agribusiness companies. The study hypothesizes that the willingness and...

Ano: 2004 URL: http://purl.umn.edu/16089 Research Investments and Market Structure in the Food Processing, Agricultural Input, and Biofuel Industries Worldwide AgEcon Fuglie, Keith O.; Heisey, Paul W.; King, John L.; Day-Rubenstein, Kelly A.; Schimmelpfennig, David E.; Wang, Sun Ling. Meeting growing global demand for food, fiber, and biofuel requires robust investment in agricultural research and development (R&D) from both public and private sectors. This study examines global R&D spending by private industry in seven agricultural input sectors, food manufacturing, and biofuel and describes the changing structure of these industries. In 2007 (the latest year for which comprehensive estimates are available), the private sector spent $19.7 billion on food and agricultural research (56 percent in food manufacturing and 44 percent in agricultural input sectors) and accounted for about half of total public and private spending on food and agricultural R&D in high-income countries. In R&D related to biofuel, annual...

Ano: 2005 SIZE AND DISTRIBUTION OF MARKET BENEFITS FROM ADOPTING BIOTECH CROPS AgEcon Price, Gregory K.; Lin, William W.; Falck-Zepeda, Jose Benjamin; Fernandez-Cornejo, Jorge. This study estimates the total benefit arising from the adoption of agricultural biotechnology in one year (1997) and its distribution among key stakeholders along the production and marketing chain. The analysis focuses on three biotech crops: herbicide-tolerant soybeans, insect-resistant (Bt) cotton, and herbicide-tolerant cotton. Adoption of these crops resulted in estimated market benefits of $212.5-$300.7 million for Bt cotton, $231.8 million for herbicide-tolerant cotton, and $307.5 million for herbicide-tolerant soybeans. These benefits accounted for small shares of crop production value, ranging from 2 percent to 5 percent. U.S. farmers captured a much larger share (about a third) of the benefits for Bt cotton than with herbicide-tolerant soybeans...

Ano: 2003 URL: http://purl.umn.edu/33562 The U.S. Patent System and Developing Country Access to Biotechnology: Does the Balance Need Adjusting? AgEcon Taylor, Michael R.; Cayford, Jerry. Many agricultural and food security experts believe that biotechnology has potential to assist developing country farmers in meeting current and future food needs. Most of the tools of biotechnology have been developed, however, by companies, governments, and universities in industrialized nations; are the subject of U.S. patents; and have so far been applied commercially to address the needs of large-scale growers in the United States and other developed countries. For commercial and other reasons, applications of biotechnology that might benefit developing country farmers are unlikely in the foreseeable future to be developed and disseminated through commercial channels. At the same time, noncommercial, public sector researchers report that their access...

Ano: 2002 URL: http://purl.umn.edu/10872 VALUATION OF INTERNATIONAL PATENT RIGHTS FOR AGRICULTURAL BIOTECHNOLOGY: A REAL OPTIONS APPROACH AgEcon Nadolnyak, Denis A.; Sheldon, Ian M.. Uncertainty of returns from marketing is an extremely important factor affecting the diffusion of a wide range of genetically modified (GM) crops worldwide. Biotech companies face complicated choices in making decisions about whether to enter agricultural markets in different countries with their agricultural products. In this paper, we model these choices as a real option problem of entry decision solved at a micro-level by individual firms. The model is aggregated in order to reflect the heterogeneity of different genetic events, as well as different markets, in terms of their profitability. The solution to the model produces distributions of entry probabilities as functions of the functional forms (and parameter values) that govern the evolution of...

Ano: 2003 URL: http://purl.umn.edu/21982 VERTICAL AND HORIZONTAL COORDINATION IN THE AGRO-BIOTECHNOLOGY INDUSTRY: EVIDENCE AND IMPLICATIONS AgEcon Kalaitzandonakes, Nicholas G.; Bjornson, Bruce. Agro-biotechnology is evolving from a pre-commercial phase dominated by basic research science to a commercial phase oriented around marketing products. In pursuing innovation rents in the commercial phase, firms are reorienting their strategies around complementary marketing and distribution assets. This is impacting vertical and horizontal industry structure. Conversely, industry structure is also impacting firm strategies. Horizontal alliances and consolidation continue from the pre-commercial phase into the commercial phase, while vertical coordination and integration strategies are accelerating rapidly. Interplay between firm strategy and industry structure is too complex for firms to anticipate early in the pre-commercial phase for long-term...

Ano: 1997 URL: http://purl.umn.edu/15537 WHEAT CHARACTERISTIC DEMAND AND IMPLICATIONS FOR DEVELOPMENT OF GENETICALLY MODIFIED GRAINS AgEcon Janzen, Edward L.; Mattson, Jeremy W.; Wilson, William W.. Agricultural biotechnology is advancing rapidly and is embracing all major crops. The adoption of genetically modified corn, soybeans, and cotton have reached high levels in the United States. Wheat is the next major crop confronting the biotechnology issue, but no commercial varieties of genetically modified (GM) wheat have been released yet. Primary opportunities for GM developments in wheat center around improvements that meet consumer and end-user needs/issues in addition to meeting producer efficiencies. Developers and proponents of GM wheat must focus on education of consumers and restoration of worldwide confidence in the regulatory systems. The most desired wheat quality trait among millers and bakers is the assurance of consistent quality.
