Endogenous R&D Investment and Market Structure: A Case Study of the Agricultural Biotechnology Industry

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 recently in the market as licensing was previously precluded by high transactions costs and “anti-stacking” provisions. We extend Sutton's theoretical framework of endogenous sunk costs and market structure to incorporate the ability of firms to license technology under well-defined property rights, an observed characteristic not captured in previous analyses of the sector. Our model implies that technology licensing leads to lower levels of industry concentration then what would be found under Sutton's model, but that industry concentration remains bounded away from perfect competition as market size becomes large.licensing, market structure, R&D, agricultural biotechnology, Research and Development/Tech Change/Emerging Technologies, L22, L24, Q16,

The Bill and Melinda Gates Foundation: business versus bureaucracy in international development

New forms of aid, including “philanthrocapitalism” such as The Bill and Melinda Gates Foundation, are rapidly altering the international aid architecture for health. These organisations have financial power, actively shape agendas and influence policy. The rise of non-traditional donor organisations creates opportunities and has implications for Australia as it scales-up its aid program. AusAID could collaborate, complement, compete with, or copy these organisations. Arguably the biggest strategic implication is that they expand AusAID’s programming choices. This increased flexibility could be used to leverage and accelerate further reforms in the UN and elsewhere. But choice is a two way street. Developing countries may prefer large, grant financing from non-traditional aid organisations and choose to bypass traditional multilateral and bilateral development agencies.Aid, non-traditional donor organisations

Welfare Rankings From Multivariate Data, A Non-Parametric Approach

Economic and Social Welfare is inherently multidimensional. However choosing a measure which combines several indicators is difficult and may have unintended and undesireable effects on the incentives for policymakers. We develope a nonparametric empirical method for deriving welfare rankings based on data envelopment which avoids the need to specify a weighting scheme. The results are valid for all possible social welfare functions which share certain cannonical properties. We apply this method to data on human development.Welfare Rankings, Data Envelopment, Human development

Environmental Changes and the Dynamics of Musical Identity

Musical tastes reflect our unique values and experiences, our relationships with others, and the places where we live. But as each of these things changes, do our tastes also change to reflect the present, or remain fixed, reflecting our past? Here, we investigate how where a person lives shapes their musical preferences, using geographic relocation to construct quasi-natural experiments that measure short- and long-term effects. Analyzing comprehensive data on over 16 million users on Spotify, we show that relocation within the United States has only a small impact on individuals' tastes, which remain more similar to those of their past environments. We then show that the age gap between a person and the music they consume indicates that adolescence, and likely their environment during these years, shapes their lifelong musical tastes. Our results demonstrate the robustness of individuals' musical identity, and shed new light on the development of preferences.Comment: Accepted to be published at ICWSM'1
