Última Estimating the Adoption of Bt Eggplant in India: Who Benefits from Public-Private Partnership? AgEcon Krishna, Vijesh V.; Qaim, Matin. The study analyzes ex-ante the adoption of insect resistant Bt eggplant in India. Farmers' willingness to pay (WTP) is estimated using the contingent valuation method. Given the economic importance of insect pests, the average WTP for proprietary Bt hybrids is more than four times the current price of conventional hybrids. Since the private innovating firm has shared its technology with the public sector, it is likely that public open-pollinated Bt varieties will also be released after a small delay. This will reduce farmers' WTP for Bt hybrids by 35%, thus decreasing the scope for corporate pricing policies. Nonetheless, ample profit potential remains. Analysis of factors influencing farmers' adoption decisions demonstrates that public Bt varieties will...

Ano: 2006 URL: http://purl.umn.edu/25311 BIODISCOVERY AND INTELLECTUAL PROPERTY RIGHTS: A DYNAMIC APPROACH TO ECONOMIC EFFICIENCY AgEcon Dedeurwaerdere, Tom; Krishna, Vijesh V.; Pascual, Unai. This paper examines the use the use of economic incentives for knowledge generation through biodiscovery, in the particular case of the use of a highly valuable biogenetic resource stock from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from institutional and ecological economics. Two important conclusions come out of this analysis. First, it highlights the necessity to go beyond standard market approaches to economic valuation in order to address the issues of future possibilities of use and innovation and the integration of the different stages in the process of value creation. Second, it shows the necessity of developing alternatives to the current intellectual...

Ano: 2005 URL: http://purl.umn.edu/31928 Pesticide Reduction Sustainability of Bt Technology in India AgEcon Krishna, Vijesh V.; Qaim, Matin. The primary focus of the study is the changes that occurred in the pesticide-use structure of cotton production sector of India, owing to the diffusion of Bacillus thuringiensis (Bt) technology. Studies from different countries show that transgenic Bt crops can reduce chemical pesticide use with positive economic, environmental, and health effects. However, most of these studies build on cross-section survey data, so that longer term effects are uncertain. Bt resistance and secondary pest outbreaks may potentially reduce or eliminate the benefits over time, especially in developing countries where refuge strategies are often not implemented. Here, data from a unique panel survey of cotton farmers, conducted in India between 2002 and 2008, show that the Bt...

Ano: 2011 URL: http://purl.umn.edu/114696 Bioprospection Beyond Intellectual Property Rights: The Kani Model of Access and Benefit Sharing AgEcon Pascual, Unai; Dedeurwaerdere, Tom; Krishna, Vijesh V.. This paper addresses the value of bioprospection for genetic resources (GR) and traditional knowledge (TK) from the South for industrial/research input. The focus is on a dynamic approach to contracting and property rights building upon insights from evolutionary institutional economics. Drawing on a unique 'access and benefit sharing' (ABS) bioprospecting contract from the Western Ghats, India, we show how the monetary value of plant genetic information from the traditional knowledge holders' perspective can be assessed using a contingent valuation modelling approach. While the study allows the identification of such values from one of the main stakeholder's (i.e, the Kani community) perspective, it also allows to point out some of the key gaps in the...

Ano: 2006 URL: http://purl.umn.edu/25377 Potential Impacts of Bt Eggplant on Economic Surplus and Farmers’ Health in India AgEcon Krishna, Vijesh V.; Qaim, Matin. In this article, the potential impacts of Bt eggplant technology in Indian agriculture are analyzed. Several proprietary Bt hybrids are likely to be commercialized in the near future. Based on field trial data, it is shown that the technology can significantly reduce insecticide applications and increase effective yields. Comprehensive farm survey data are used to project farm level effects and future adoption rates. Simulations show that the aggregate economic surplus gains of Bt hybrids could be around US $108 million per year. Consumers will capture a large share of these gains, but farmers and the innovating company will benefit too. As the company has also shared its technology with the public sector, Bt open-pollinated varieties might become...

Ano: 2007 URL: http://purl.umn.edu/9909 Channeling consumption preferences for co-existence of landrace and modern varieties in-situ AgEcon Krishna, Vijesh V.; Pascual, Unai; Zilberman, David. The study examines the least-cost option of conserving landraces in-situ by the development of market friction instruments. The empirical examination is comprised of two closely-related studies on eggplant production and consumption sectors of India. An examination of the cost and return structure of eggplant farming in the study area reveals that the incremental farm price of eggplant products of landrace origin eclipses the yield advantage of hybrid varieties. Possibly due to the information asymmetries and other imperfections existing in this market, the price increment currently realized by the eggplant farmers is still only a fraction of consumers’ willingness to pay for landraces. This wide margin is indicative of the unexploited potential of...

Ano: 2009 URL: http://purl.umn.edu/51748 GM Technology Adoption, Production Risk and On-farm Varietal Diversity AgEcon Krishna, Vijesh V.; Zilberman, David; Qaim, Matin. This paper examines the impact of transgenic technology adoption on varietal diversity. Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse agro-biodiversity impact might be partially counteracted by an expanding seed sector, supplying a large number of transgenic varieties. The case of Bt cotton in India is taken for empirical illustration. The production function analyses show that both Bt technology and on-farm varietal diversity enhance yield, while reducing the production risk. With few Bt varieties available in the first years, technology adoption entailed a reduction in on-farm varietal diversity. This...
