Non Technical Summary
NON-TECHNICAL SUMMARYThe purpose of this project is to examine contemporary issues concerning international trade and technology policy that have significant impacts on the economic welfare of human beings. The project includes research on five broad and overlapping questions: (1) What are the implications of patents for farmers' decisions to use genetically modified seed vs. traditional non-genetically modified seed? (2) What are the supply-side determinants of international trade in crops that are intensive in genetically modified organisms? (3) What are the effects of intellectual property rights on the economic growth of countries? (4) To what extent are country policies toward genetically modified organisms "trade related?" (5) What are the welfare effects of national and international policy options that support economic development through international technology transfers?The economic methods will varying to fit the project goals and questions described above. The theoretical approaches include game theory, general equilibrium models of international trade (including the Heckscher-Ohlin and Gravity models), macroeconomic growth model, and benefit-cost analysis, respectively. The prominent empirical approach is to examine the questions thematically for all countries that comprise the global economy. Thus, the research will rely primarily on panel data which are detailed by country, by year, and by industry (as appropriate to the model).The ultimate goals of the project are to examine the effects of policy decisions (e.g., intellectual property rights, GMO regulations, technology transfer policies) on the economic welfare of stakeholders at the national and global levels. Stakeholders include consumers, producers (e.g., farmers), innovators (e.g, seed firms), and governments within national communities and globally.

Goals / Objectives
GOALSThe over-arching goal of the project is to analyze contemporary and frontier issues concerning international trade and technology policy. Specifically, the project will contribute to scholarly knowledge at the nexus of the subjects of: (a) intellectual property rights; (b) genetically modified organisms; (c) international trade; (d) economic growth; (e) international economic development; and (f) international technology transfers.The objectives of the proposed research are to examine the following:Implications of patents for farmers' decisions to use genetically modified seed vs. traditional non-genetically modified seed.Supply-side determinants of international trade in crops that are intensive in genetically modified organisms.Effects of intellectual property rights on the economic growth of countries.Extent to which country policies toward genetically modified organisms are "trade related."The welfare effects of national and international policy options that support economic development through international technology transfers.
Project Methods
METHODSThe economic methods will vary to fit the project goals as summarized below.1. Implications of patents for farmers' decisions to use genetically modified (GM) seed vs. traditional non-GM seed. The small existing literature on patents and adoption decisions includes two themes. One theme considers the implications of patents for pricing of GM seed and thus adoption decisions by farmers. The second considers the implications of patents for the diffusion of GM seeds. Smith's research will contribute new work at the intersection of these themes. Smith will consider farmers' adoption decisions in an environment where profits are a function of the payoffs from using GM seed or traditional seed, diffusion of the GM technology, effort of monitoring by the seed companies for patent violation, and cost of patent infringement. In the model, these features influence the decisions to adopt traditional non-GM seed, adopt GM seed legally, or adopt GM seed illegally. Smith's research will contribute a distinctive methodology. The research will apply an evolutionary game theoretic approach to analyze the economic decisions of farmers to adopt GM vs. non-GM seed. This methodology is familiar to evolutionary biologists who use it to analyze the evolution of traits over time based on the benefits they provide. Smith will use the replicator equation to analyze the dynamics of farmers' adoption decisions across time where the benefits are profits. There are no other studies of this topic that use this methodology.2. Supply-side determinants of international trade in crops that are intensive in genetically modified organisms (GMOs). The goal is to quantify the supply-side determinants of trade in industries dominated by GMOs. The research will focus on soybeans, maize, and cotton as these industries have the largest shares of global area planted in GMOs. First, Smith will examine the determinants of comparative advantage by applying the Heckscher-Ohlin (HO) model which predicts comparative advantage based on country differences in endowments. Second, Smith will adapt the model by decomposing country land endowments into GMO and traditional components. This adaptation will allow Smith to examine the effect of an increase in a country's allocation of land to GMOs on comparative advantage. Third, Smith will examine how the determinants of trade have changed over time in the wake of GMO adoption globally. Smith will compare trade prior to the advent of GMOs (1995) and 15 years following (2010). Smith will use cross-section data to examine points in time, and panel data to examine deviations in effects across time. This econometric approach allows for assessment of whether the sources of comparative advantage have changed over time, and whether the reallocation of land to GMOs has contributed to changes. Fourth, Smith will examine the trade effects of country differences in policies toward approval process, risk assessment, labeling policies, traceability requirements, coexistence guidelines, and international treaties. Smith will also consider the trade-effects of policy portfolios by examining alternative weighting of policies. There are currently no such studies in the literature.3. Effects of intellectual property rights (IPRs) on the economic growth of countries. This research will examine the effects of IPRs on the economic growth of countries. The growth literature shows that the net effect of IPRs on growth is ambiguous because it depends on the relative importance of the channels that link IPRs with growth. Thus, Smith's first goal is to empirically examine the direction of the net effects of IPRs. Second, East Asia (EA) provides a unique case for considering IPRs and growth because of the regions strong capacity for imitation combined with weak institutions for protecting intellectual property. Thus, Smith's second goal is to examine the growth effects of IPRs in EA relative to the rest of the world. Third, the 1995 TRIPs Agreement of the WTO brought about a major strengthening of IPRs globally. Proponents (industrialized countries) argued that strengthening IPRs would have positive growth effects. However, developing countries raised concerns that the negative effects of strong IPRs could outweigh the benefits. Thus, Smith's third goal is to determine whether TRIPs altered the growth effects of IPRs. Fourth, the incentives for adopting strong IPRs vary considerably across countries at different development levels. Existing research suggests that less developed countries benefit from weak IPRs, while industrialized countries benefit from strong IPRs. Smith's fourth goal is to determine whether there is a development threshold that alters the growth effects of IPRs. The theoretical method involves adapting a macro growth model to distinguishes capital as physical, human, and intellectual. The empirical method includes estimating specifications using panel data across countries for 1980-2010. Econometric techniques include threshold regression methods.4. Extent to which country policies toward genetically modified organisms are "trade related." This research will examine the extent to which the GMO policies of countries are "trade-related." The research will focus on trade in soybeans and maize (which are the industries with the largest shares of GMO content globally), and on Latin America (which is at the forefront of the developing world in grappling with trade aspects of GMO policies). The international trade literature on GMOs is in its infancy. Primary modeling approaches include computable general equilibrium, game theory and partial equilibrium models. Empirical trade studies are few. The literature on GMOs in LA is relatively more developed but dominated by descriptive case studies. There are no econometric studies for LA that quantify the effects of GMO policies on bilateral trade. Smith's research will fill this gap. Smith will examine the extent to which GMO policies are trade related. First, Smith will construct measures of "revealed comparative advantage" using the Balassa index and use these measures to assess the comparative advantage of LA countries relative to the region and relative to the world. Smith will then estimate adaptations of the Gravity model to examine the effects of importers GMO policies on the bilateral exports of LA countries in soybeans and maize.5. Welfare effects of national and international policy options that support economic development through international technology transfers. This research will examine the welfare effects of technology transfer policies. The broad goal is to determine the relative effectiveness of policy alternatives in promoting economic development, particularly in the poorest countries of the world. In practical terms, the research will contribute to the process of prioritizing goals. In September of 2015, the United Nations (UN) will select a list of Sustainable Development Goals for the world to meet by 2030. To develop the new agenda, an Open Working Group has convened to identify challenge areas and target goals within each area. To help prioritize the goals, the Copenhagen Consensus Center assembled leading economist to undertake research. The purpose is to identify the goals that yield the largest returns for economic and social development. The methodology involves benefit-cost analysis of the goals under consideration and ranking by effectiveness. Ultimately the goal is to help the UN determine the direction of development aid to countries. Smith will undertake research in the area of international technology transfers. Smith's purpose is to assess current policy proposals and to provide perspectives on policy options. Smith's research will examine the channels for technology transfers, economic conditions that support technology transfers, and policies suited for countries at different development levels.

The research outputs have been disseminated in multiple ways. The research is available for download from the website of The Copenhagen Consensus. The research has been reviewed by an Expert Panel (including three Nobel Laureates) who have used the research to make recommendations to the United Nations on policy priorities for economic development. The research has been featured in prominent media outlets (e.g., Wall Street Journal, Time.com, Reuters, The Guardian, The Telegraph) through published articles and editorials in both the developed and developing worlds. The research has been summarized in Foreign Affairs and featured on the radio podcasts (e.g., Freakanomics). Most importantly, the research has been disseminated to 500+ UN ambassadors, staffers and decision makers within the development community who are responsible for making decisions regarding aid to developing countries. Finally, the remaining output published by John Wiley & Sons, Inc. has been made accessible internationally for use by instructors of courses on trade and policy.
