1. Introduction Rice = most important food crop of the developing world Worldwide, more than 3.5 billion people depend on rice for more than 20% of their daily calorie intake Staple food of more than half of the world’s population Many of whom are also poor & therefore extremely vulnerable to high rice prices International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012

1. Introduction Rice world market = thin, fragmented, inelastic domestic demand, low world stockholdings unstable GM rice may have substantial implications For alleviation of poverty, hunger, and malnutrition in rice growing & consuming countries (James, 2005) For global acceptance of GM crops (Brookes & Barfoot, 2003) International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012

Introduction International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012 However, in 2012 nowhere in the world has GM rice been commercialized at a large scale Important existing and expected approvals: Approval of Bt rice in China Expected commercial approval of Golden Rice in the Philippines in 2013/14 Important for the developing world Is commercialization imminent? Review evidence on global value of GM rice However, in 2012 nowhere in the world has GM rice been commercialized at a large scale Important existing and expected approvals: Approval of Bt rice in China Expected commercial approval of Golden Rice in the Philippines in 2013/14 Important for the developing world Is commercialization imminent?

2. Methods Almost no ex-post evidence ex-ante Field trials vs. on-farm trials ANOVA, (stochastic) partial budgeting vs. econometric techniques Assumptions (e.g. technology licensing fee) Exogenous vs. endogenous technology fee Partial equilibrium models vs. CGE Disability-adjusted life years (DALYs) approach International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012

Metrics International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012 1.Anticipated impacts are in line with classic examples of commercialized first-generation GM crops Impact of stress-resistant GM traits = f(stress incidence/severity & use of damage control inputs, e.g. herbicides, insecticides, water) Impact of Bt rice in China ranges from +0–12% yield advantage to –50–90% insecticide use DT rice in China: –13% yield variance, –33% water 1.Anticipated impacts are in line with classic examples of commercialized first-generation GM crops Impact of stress-resistant GM traits = f(stress incidence/severity & use of damage control inputs, e.g. herbicides, insecticides, water) Impact of Bt rice in China ranges from +0–12% yield advantage to –50–90% insecticide use DT rice in China: –13% yield variance, –33% water

4. Critical Assessment Four limitations: 1.Proprietary seed technologies Monopolistic rent extraction Endogeneize technology licensing fee (Demont et al., 2009; Dillen et al., 2009; Konstandini et al., 2009) 2.Focus on first-order statistics (e.g. of yields) DT rice: yield variance reductions Represents 40% of the total benefits in Asia (Konstandini et al, 2009) International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012

4. Critical Assessment Four limitations: 3.Modeling strategies Hicks-neutral productivity shocks Ex-post evidence shows shocks = factor-biased Consider trade effects, restrictions 4.Challenge of transforming DALYs $ values What is the value of a DALY? $500, $1000, GDP, GNI? CGE captures economy-wide impacts (Anderson et al., 2005a, 2005b) International Consortium on Applied Bioeconomy Research (ICABR) 16th Annual Conference on “The Political Economy of the Bioeconomy: Biotechnology and Biofuel”, Ravello, Italy, 24–27 June 2012
