    Description: Welfare trade-offs between intellectual property (IP) protections provided by patents and by plant variety protection (PVP) are explored. PVP breeders’ exemption weakens IP protection, but may speed the transfer of research gains across firms. A model is developed assuming firms optimise research given existing IP protection. A baseline scenario supporting each system is used to perform welfare analysis, and study how the balance is altered between systems. Survey data suggest patents are more appropriate for longer-term, higher-risk research, whereas PVP is better suited for traditional breeding. A scenario where patents and licensing co-exist dominates PVP in all commercially relevant areas.

    Description: Using subregional models of crop production choices in central Wisconsin and southwest Michigan, we predict biomass production, land use, and environmental impacts with details that are unavailable from national scale models. When biomass prices are raised exogenously, we find that the subregional models overestimate the supply, the land use, and the beneficial environmental aspects of perennial biomass crops. Multi-market price feedbacks tied to realistic policy parameters predict high threshold absolute prices for biomass to enter production, resulting in intensified production of biomass from annual grain crops with damaging environmental impacts. Multi-market feedbacks also predict regional specialization in energy biomass production in areas with lower yields of food crops. Policies promoting biofuels will not necessarily generate environmental benefits in the absence of environmental regulations.

    Description: Domestically funded (and performed) research and development (R&D) has historically been a major source of productivity gains in U.S. agriculture, and a principal source of R&D spillovers to the rest of the world. In the waning decades of the 20th century, U.S. policymakers opted to ratchet down the rate of growth in public support for food and agricultural R&D. As the 21st century unfolds, slowing growth has given way to real cutbacks, reversing the accumulation of U.S.-sourced public R&D capital over most of the previous century and more. The 2014 Farm Bill did little to reverse these long-run research funding trajectories—politicians failed to heed the economic evidence about the still substantial social payoffs of that research and the consequent slowdown in U.S. agricultural productivity growth associated with the spending slowdown. Meanwhile, R&D spending by other countries has been moving in different directions. We present new evidence that today's middle-income countries—notably China, Brazil, and India— are not only growing in relative importance as producers of agricultural innovations through investments in public R&D, they are also gaining considerable ground in terms of their share of privately performed research of relevance for agriculture. The already substantive changes in global public and private R&D investment trajectories are accelerating. If history is any guide to the future, these changing R&D trajectories could have profound consequences for the competitiveness of U.S. agriculture in the decades ahead.

    Description: Private sugar processors in Andhra Pradesh, India use an unusual form of vertical coordination. They issue ‘permits’ to selected cane growers a few weeks before harvest. These permits specify the amount of cane to be delivered during a narrow time period. This article investigates why processors create uncertainty among farmers using ex post permits instead of ex ante production contracts. The theoretical model predicts that ex post permits are more profitable than ex ante contracts or the spot market under existing government regulations in the sugar sector, which include a binding price floor for cane and the designation of a reserve area for each processor wherein it has a legal monopsony for cane. The use of ex post permits creates competition among farmers to increase cane quality, which increases processor profits and farmer costs. Empirical analysis supports the hypothesis that farmers operating in private factory areas have higher unit production costs than do their counterparts who patronize cooperatives.

    Description: The authors incorporate brain activation data in an analysis of decision time and choices for milk labeled as produced with growth hormone or cloning technologies, or labeled as conventional milk. Non-hypothetical choices and decision time are correlated with blood oxygenation level-dependent extractions in brain regions previously found to be involved in valuation. The significance of the activations related to price and production technology differs in models of decision time and choice. More areas influence the time it takes to make a decision. The final decision appears to be most correlated with localized areas in the medial prefrontal cortex, with a higher correlation when the choice is about growth hormones than cloning technology.

    Description: This article analyzes the relation between investment age, measured as the number of years since investment spike, and dynamic productivity growth and its components, which include dynamic technical change, dynamic inefficiency change, and dynamic scale inefficiency change. The empirical application focuses on firm-level data for the Spanish food processing industry covering the period from 1996 to 2011. This investigation of the impact of firms' investment decisions on productivity growth employs a dynamic production framework and analyzes the impact of these decisions on the components of dynamic productivity growth. Our findings show that dynamic productivity growth is negatively affected by investment spikes in both the meat processing and oils and fats industries, and that dynamic inefficiency change initially falls just after the infusion of large investment for oils and fats firms, but then grows as the firms acquire experience with this investment. We further find that investment spikes lead to improvements in dynamic technical change and worsening in dynamic technical inefficiency change in the meat processing industry, while dynamic scale inefficiency change was negatively impacted in both industries.

    Description: Supermarkets face a two-sided demand for shelf space: consumers demand variety and suppliers demand shelf space. We exploit the asymmetric ability of consumers and suppliers to internalise network effects to derive a novel test of network effects in multi-product retail markets. Because consumers fully internalise network effects but suppliers cannot, retail margins rise and wholesale margins fall as variety increases. We test this hypothesis using retail scanner data for a ‘shopping basket’ of items from competing retailers using a structural model of retail variety and vertical pricing. Our results support the existence of positive, two-sided network effects in supermarket retailing.

    Description: The present article is the first that analyses profit persistence in the European food industry. Based on the Arellano and Bond GMM estimator, the degree of profit persistence and the drivers of persistence are quantified for a large sample of food processing firms. The analysis reveals that the degree of profit persistence in the food industry is lower compared with other manufacturing sectors due to strong competition among food processors and high retailer concentration. Furthermore, firm size is an important driver of persistence, while firm age, risk and R&D intensity have a negative influence.
