"District Subdivision and the Location of Smallholder Forest Conversion in Sumatra"

A unique GIS data set from Indonesia that distinguishes smallholder and plantation operations is used to test the impact of district subdivision, which enhances local control of natural-resource revenues, on the location of smallholder forest conversion. Nonparametric analyses find that in subdivided districts, smallholders convert forests on steeper land that is further from the nearest road and deeper into the forest. Smallholders are also less responsive to forest protection in subdivided districts. District subdivision imposes a welfare loss of $1,734 to $5,256 per hectare (in 2010 USD) from the increased carbon emissions associated with smallholder conversion deeper in the forest.

“Are Innovations Really Induced by Input Price Changes?"

Technological innovations in agriculture and elsewhere, of course, follow from advances in general scientific knowledge. But the development of technologies can also be driven by input prices - escalating prices for one particular input encourage development of new technology that substitutes for that input. This "induced innovation" hypothesis has been widely examined by economists, but despite its intuitive appeal, it has received limited empirical support. Professor Shumway will present some new research findings relevant to this puzzle.

“The Governance of Federations"

Organization theorists and management scholars have thus far overlooked the prevalence and success of enterprise federations, a group of organizations that form a central to provide themselves with purchasing, wholesaling, manufacturing, logistics, technical and/or other services. Many enterprise federations are structured as cooperatives – examples include Home Hardware and Federated Co-operatives Limited. What is intriguing about a federation vis-à-vis other forms of governance is not that it co-ordinates activities between organizations, nor that it features a central enterprise, but rather that power is shared between the central enterprise and the autonomous constituent organizations that own the central and are the primary users of its services. According to insights derived from transaction cost analysis and agency theory, the additional costs associated with collaborative governance should render federations more inefficient than conventional governance models, leading them either to centralize completely or fail. The questions posed in this paper is: Why do federations continue to exist, and in some cases even thrive, in competitive industries where presumably more efficient forms of governance are possible? In other words, what, if anything, does federated governance add to compensate for the additional costs of greater collaboration in decision-making?

“Rural Economic Transformation in the Senegal River Valley"

Over the past 50 years attempts modeled on the Green Revolution to catalyze transformation in remaining low-income countries, which rely importantly on subsistence agriculture, have met limited success—and global political, economic and social forces have rapidly changed the development context.  This begs the question: what does successful structural transformation of an agricultural economy look like today? An empirical case study of what is arguably the beginning of a contemporary rural economic transformation process in the Senegal River Delta provides a potential answer. The study adds to the traditional measures of transformation—agricultural technology adoption and staple-crop productivity increases—to include measures of institutional change, business development and rural non-farm employment, among others.

Three conclusions emerge.  First, evidence suggests a shift from subsistence to commercial farming, which is consistent with neo-classical structural transformation.  Second, there appears to be increasing business activity, employment and population growth in rural towns and small cities that is consistent with a local structural transformation, but at least preliminarily differs in nature from classical structural transformations that historically are associated with widespread migration out of rural areas including small towns and into large urban metropolises. Third, the nature of the transformation cannot be captured adequately with only agricultural technology and productivity indicators.

“A Safer Catch? The Effect of Catch Share Management on Risk Taking and Safety in Commercial Fishing"

Commercial fishing is a dangerous occupation despite decades of regulatory initiatives aimed at making it safer. We posit that rights-based fisheries management (the individual allocation of fishing quota to vessels or fishing entities, also called catch shares) can improve safety by solving many of the problems associated with the competitive race to fish experienced in fisheries around the world. The competitive nature of such fisheries results in risky behavior such as fishing in poor weather, overloading vessels with fishing gear, and neglecting maintenance. Although not necessarily intended to address safety issues, catch shares eliminate many of the economic incentives to fish as rapidly as possible. We develop a dataset and methods to empirically evaluate the effects of the adoption of catch shares management on a particularly risky type of behavior: the propensity to fish in stormy weather. After catch shares was implemented in an economically important US West Coast fishery, a fisherman’s probability of taking a fishing trip in high wind conditions decreased by 82% compared with only 31% in the former race to fish fishery. Overall, catch shares caused the average annual rate of fishing on high wind days to decrease by 79%. These results are evidence that institutional changes can significantly reduce individual, voluntary risk exposure and result safer fisheries.

“Leveraging the Lotto for Financial Inclusion: Lotto-Linked Savings Accounts in Haiti”

Many Haitians are more familiar with lottery wagers than any other financial transaction and few have access to savings products. In Port-au-Prince, we asked 306 participants to make a series of decisions to allocate a fixed budget across consumption, a real-world lotto product, a real-time traditional savings product, and a lotto-linked savings product (LLS) that blended the two by providing lotto credit in lieu of interest payments. We find that the introductions of LLS increased total savings by 22 percent, an increase roughly equivalent to that induced by raising the interest rate on the traditional savings product from 5 to 20 percent. An LLS with a small lotto incentive was equally effective as an LLS with a larger lotto incentive in increasing total savings, excluding expected lotto winnings. An LLS product with a lower expected return than the traditional savings product was equally effective as an LLS that had the same expected return as the savings product. The introduction of LLS reduced allocation in all of the three other options: consumption, lotto, and traditional savings. Bu the reductions were largest for lotto spending and the amount saved in the traditional savings product. We find evidence that the LLS was effective at increasing savings at least partly because individuals overweight small probabilities.

“Examining Consumer Food Waste: Evidence from Two Experimental Studies”

Although food waste is increasingly recognized as an environmental and food security problem, there remains uncertainty over its primary contributors. Some food waste analyses seem to treat consumer (household) food waste as a “mistake” or careless decision; however, consumer decisions to waste likely reflect tradeoffs and economic incentives. These issues were explored in two experimental studies. In the first, we employ large surveys of U.S. food consumers using both within- and between-subject designs to study consumers’ decisions to discard food in different scenarios that vary safety, price, and opportunity costs. We find that food waste is a function of consumers’ demographic characteristics, and that decisions to discard food vary with economic incentives (paper attached). In the second, preliminary results are presented on the impact of an educational campaign to reduce food waste in university dining facilities.

“Education and Factor Bias in Agriculture and Related Industries"

The number of hours devoted to value-added output in the NAICS sector Agriculture, Forestry, Fishing and Hunting is increasingly supplied by individuals with advanced schooling. Consistent with hypotheses of a positive relationship among technology development, adoption, and dissemination and a skilled workforce, we find that the composition of the workforce is closely aligned with measures of the state of technology and with labor saving biases resulting from technical change. The changing composition of the workforce and technical change have driven an average wedge of 31% between reported wages W and wages augmented by the state of technology W*.  Reported labor compensation in the sector was about $89 billion in 2010, with an average wage index of 110.9.  The augmented labor wage index in 2010 was about 68.7, a loss of about 38%, whereas capital price increased from 121.9 (PC) to 196.7 (PC*).

“Object Allocation via Immediate-Acceptance: Characterizations and an Affirmative Action Application"

Which mechanism to use to allocate school seats to students still remains a question of hot debate. Meanwhile, immediate acceptance mechanisms remain popular in many school districts. We formalize desirable properties of mechanisms when respecting the relative rank of a school among the students' preferences is crucial. We show that those properties, together with well-known desirable resource allocation properties, characterize immediate acceptance mechanisms. Moreover, we show that replacing one of the properties, consistency, with a weaker property, non-bossiness, leads to a characterization of a much larger class of mechanisms, which we call choice-based immediate acceptance mechanisms. It turns out that certain objectives that are not achievable with immediate acceptance mechanisms, such as affirmative action, can be achieved with a choice-based immediate acceptance mechanism.

“Generating and Using Focused Big Data for N Fertilizer Management"

Recent research has used precision agricultural technology (PAT) to run large-scale field trials that greatly reduce the cost of data generation. We explore the economic value of such trials. We report results of Monte Carlo simulations in which information generated in trials is used to improve farm management in subsequent years. A key result is that in our simulations the value of PAT is not based on its making variable rate management feasible. Rather, most of the value of PAT comes from the improved management made possible by the information derived from the field trials the technology permits.<

“Incentives and Rewards to Innovation in a Rapidly Changing Global Environment"

The 4th industrial revolution, already upon us, promises jobless growth with technology replacing humans and knowledge and skills trumping physical capital. Creating gainful employment for millions is at the center of the cataclysmic political changes and policy concerns throughout the world. Dr. Uma Lele will outline how, and how well, developing regions are undergoing changes in incentives for rapid broad based and sustainable growth, in the context of the highly different resource endowments and the departure from the traditional concept of structural transformation. Questions related are, for example, is large scale farming inevitable? Is it part of a power law? What does it mean for those excluded from the process of structural transformation? How can productive employment be expanded to absorb workers displaced from robotized technological change? Lele will assert that social science research is sorely needed but lacking.

“Animal Agriculture Facing Pressure from Regulations and Private Standards"

Filley-Garey Lecture


Abstract: Animal agriculture faces pressures from government regulations and private buyer standards, including those related to labeling. This presentation will review economic relationships for several important issues related to poultry, pork, beef and milk industries. These issues have a common theme: widespread concerns about farm or food system practices are based on misperceptions or misinterpretations. Also, that changes in practices and product characteristics have been imposed by government regulation or intermediate buyer standards that limit consumer choices, rather than by effective market demand by end use consumers.

Among the most significant implications of these trends in animal agriculture are disincentives for application of science and technology to agricultural and food practices. Such disincentives for innovation may foster slower farm and food system productivity growth, slower declines in food prices, slower improvements in food safety, and slower reductions in food waste. In rich, relatively well-fed economies the impacts are substantial but affect a relatively small part of the economy and a small share of most consumer budgets. Among the poor of the world, the consequences are vital and include less nutritious diets and resultant health threats for a billion people.

"Willingness to Pay for Ethanol in Motor Fuel: Evidence from Revealed and Stated Preference for E85"

Abstract: The relative preferences of motorists for E10 and E85 in different regions of the United States were estimated. An intercept survey of motorists with flex-fuel vehicles at E85 fuel stations in IA, CO, OK, AR and CA was conducted. A hypothetical scenario was proposed to each motorist where either the price of the fuel selected (not selected) was increased (decreased). Fuel preferences were estimated using both the revealed preference data from observed choices and the stated preference date from the hypothetical price scenario. We find that motorist significantly discount E85 compared to E10 even when adjusting for the different energy content of the two fuels and that the distribution of willingness to pay for E85 does not vary significantly between regions, except that flex motorists in California are willing to pay more for E85.

"The Value of Social Capital in Cropland Leasing Relationships"

Abstract: In the U.S. economy, informal bargaining between persons for services or assets of relatively high value is uncommon. However, there is one example encountered frequently in agriculture: the cropland lease. Many farmers rent at least a portion of their cropland and typically no formal markets exist for pricing land. This reliance on informal bargaining for the primary capital asset in farming suggests lease rates and the relationship between landowner and tenant have significant economic implications. If the existence of a long-lived and close relationship affect the rates at which the land is leased, then, cropland leases offer a unique test of the theory of social capital.

"Why Choice Matters and Why it Doesn't: An Application to Food Policy"

Abstract: In the attempt to curb the obesity crisis, policymakers are taking ever stronger measures. Recently this has resulted in several high-profile cases of backlash, with consumers complaining that their choices are being limited. Economic models of behavior predict that consumers will respond to changes in price in a way that is independent of the source of the price change. Yet research indicates that consumers that are emotionally attached to a consumption good or other behavior might respond with resistance when policies threaten their consumption or behavior. Using both survey and experimental data, we demonstrate how such emotional responses can create hidden costs to policy implementation that could not be detected using standard welfare economic techniques.  We propose a partial equilibrium model of emotional response to policy whereby preferences are endogenous to policy choices. We propose that confrontational policies (such as a tax or quota) increase the marginal utility for a good, and that validating policies (such as a subsidy) also increases the marginal utility for a good. A social planner that ignores potential emotional responses to policy changes may unwittingly induce significant dead weight loss. Using our model, we propose a feasible method to determine if emotional deadweight costs exist, and to place a lower bound on the size of these costs.

"Causes and Consequences of Open Space in U.S. Urban Areas" 

Abstract: The large variation in the share of land in open space across U.S. urban areas raises some interesting questions: a) what are the key factors that determine the amount of open space in an urban area? b) how does open space conservation affect property values and local public finance and services? and c) is the existing amount of open space in U.S. urban areas socially optimal? In this paper, we conduct theoretical and empirical analysis to address these issues. Results suggest that a significant share of U.S. urban areas have too little open space in the sense that even if additional open space would not provide any amenities, it would still increase total land values and social welfare. On the other hand, for more than 10% of U.S. urban areas, the total value of environmental benefits from open space must be at least as large as the total land value to justify for the amount of open space they have. Some of these urban areas likely have too much open space.

Abstract: High corn prices cause more land to be planted to corn, which increases the use of nitrogen fertilizer. Some of this nitrogen flows into waterways and causes serious environmental damage. We estimate that nitrogen losses are highly inelastic with respect to crop prices, but that the absolute losses can still be large. Our results suggest that changes in corn and soybean prices due to the U.S. ethanol mandate have expanded the size of the hypoxic zone in the Gulf of Mexico by roughly 288 square miles on average. To obtain these estimates, we use a panel of field-level crop data derived from satellite imagery. We merge these data with predictions from the Soil and Water Assessment Tool (SWAT) to estimate nitrogen losses by field. Our econometric model allows for substantial spatial heterogeneity, which is important for reducing bias in dynamic panel estimates and accounting for possible correlation between acreage response to price and nitrogen losses.

Abstract: The Federal Crop Insurance program has expanded dramatically over the past two decades—from $140 million in subsidies and 84 million acres covered to nearly $10 billion in subsidies and 260 million acres covered. The effect this has had on farmers' credit demand and investment behavior is unclear. Self-selection and market dynamics have masked the direct effect of crop insurance. This paper uses numerous changes to the crop insurance program to isolate crop insurance's direct effect on credit demand and, ultimately, investment. I find that crop insurance increases debt holdings—suggesting that farmers are transferring risk to the taxpayer. Crop insurance also causes farm investment to increase, suggesting that the program may also solve market failures.

Abstract: Hertel et al. (2010) examine the global impact of increasing the US corn ethanol production as a result of the 2015 conventional mandate in the RFS.  Specifically, they examine the impact on global land use changes and resulting changes in global greenhouse gas (GHGs) emissions.  In this extension of Hertel et al. (2010), the global impacts of both conventional and advanced mandate for 2015 are examined.  The analysis entails comparison of the results with the Hertel et al. (2010) using GTAP-BIO model.
The results from this extension indicate sugarcane ethanol and biodiesel may not result in less CO2 emissions.  This result is contrary to popular opinion that these biofuels produce less GHGs emissions.  The huge global land use changes associated with the implementation of the advanced biofuels mandate which mainly comprise of sugarcane ethanol and biodiesel are the primary drivers of this result.

Abstract: We examine the decision to join and contribute to an association by agents with different productivity.  We model and solve a game that explains investments to form social capital which can produce club goods for members or influence industry-wide policy.  Association products and government regulation affect membership and contribution decisions.  Government influenceability affects the decisions also, but varies with agent productivity and association output.  Often, an increase in government influenceability increases social capital in associations composed of high productivity agents because they prefer to influence policy while low productivity agents focus on production.

Abstract: Crop insurance, a government program, and futures markets, a privately operated program, exist to help agricultural producers manage income risk.  Using producer's historical yield data and futures market information; we investigate the income risk impact from these programs.  Results suggest that income protection crop insurance policy and forward contracting complement each other.  For 2012, a revenue protection crop insurance policy with enterprise units and 80% coverage level reduces income risk is by $333 per acre and increases expected income by about $24 per acre, which is due to the presence of the subsidy, over no insurance or hedging.

Abstract: There is an abundant supply of corn stover in the U.S. that remains after grain is harvested which could be used to produce cellulosic biofuels mandated by the current Renewable Fuel Standard (RFS). This research integrates the Soil Water Assessment Tool (SWAT) watershed model and the DayCent biogeochemical model to investigate water quality and soil greenhouse gas flux that results when corn stover is collected from alternative cropping systems. Together with economic estimates of the cost of each alternative, multiple watershed-scale optimizations are performed for individual pollutant-cost minimization criteria; we compare these results with a purely economic optimization that maximizes stover production at the lowest cost without taking environmental impacts into account. We illustrate tradeoffs between cost and different environmental performance criteria, assuming that nutrients contained in any stover collected must be replaced. The key finding is that stover collection using the practices modeled results in increased contributions to atmospheric greenhouse gases and sediments to waterways while reducing nitrate and total phosphorus relative to the status quo without stover collection. Our results suggest that additional information is needed about (i) the level of nutrient replacement required to maintain grain yields and (ii) cost-effective management practices capable of reducing soil erosion when crop residues are removed in order to avoid contributions to climate change and water quality impairments as a result of using corn stover to satisfy the RFS.

Abstract: For decades, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favouring their farmers with import barriers and subsidies. Both sets of policies reduced global economic welfare and agricultural trade, and almost certainly added to global inequality and poverty. Progress has been made over the past three decades in reducing agricultural protection in high-income countries and agricultural disincentives in developing countries, but the propensity of governments to insulate their domestic food market from fluctuations in international prices has not waned. Both food-importing and food-exporting countries engage in insulating behaviour, which contributes to the amplification of international food price fluctuations yet does little to advance their national food security. Thus much scope still remains to improve economic welfare and to reduce poverty by removing remaining trade distortions. This Lecture will summarize indicators of these trends and fluctuations in farm trade barriers before examining what unilateral, regional or multilateral trade arrangements, together with complementary domestic measures, could help advance global food security without risking sociopolitical unrest.

Title: "The Effect of Fast Food Restaurants on Childhood Obesity"
Paper: The Effect of Fast-Food Restaurants on School-Level Obesity
Abstract: We analyze the effect of the number of fast food restaurants at different distances from public schools in Arkansas on school-level obesity rates. We use instrumental variable estimation with fast-food restaurant proximity being instrumented by proportion of the population within the 15 to 24 year-old age group and nearness of the school to major highways. Although statistical evidence of the causal effect is mixed, results generally suggest that fast-food restaurants near schools are likely contributing to childhood and adolescent obesity. The impact of fast-food restaurants is greatest when they are within a quarter of a mile of schools and this impact declines as distance between the school and fast-food restaurants increases. The magnitudes of this impact are robust but statistical significance varied depending on model specification.

Title: "An Analysis of Selectivity in the Productivity Evaluation of Biotechnology"
Paper: An Analysis of Selectivity in the Productivity Evaluation of Biotechnology: An Application to Corn
Abstract: This paper investigates selectivity bias issues arising in the productivity evaluation of biotech hybrids, with an application to GM corn yield. The analysis is applied to experimental data on Wisconsin corn yields covering the period 1990-2010. Relying on a "Heckman-like" factor that accounts for selectivity, the analysis uncovers evidence of selection bias. It indicates that some of the observed yield advantage associated with GM hybrids is contributed by their conventional genes. This stresses that, even after the widespread adoption of GM corn in the US, traditional breeding still plays an important role in productivity improvements for corn. We also document how rising market concentration of biotech firms has contributed to increasing selectivity bias in corn yield. Our results suggest that current patenting laws may not appropriately differentiate between GM genes and conventional genes.

Title:Transaction Costs in Payment for Environmental Service Contracts
Abstract: Payment for environmental service (PES) contracts area a common means of acquiring public ecosystem goods or services from private landowners. Aside from the well-studied incentive problems with these contracts, such as hidden action and hidden information, a sparsely studied complication is the role of transaction costs in contract initiation and enforcement. This paper quanties both the individual and aggregate impacts of the transaction costs that arise from nonprice contract attributes, such as time requirements contract enrollment and compliance procedures during the contract period. Individual agents were found to incur widely varying transaction costs from these attributes, but on average transaction costs comprise a significant portion of contract willingness-to-accept. At the aggregate level, transaction costs were found to create a significant drain on the cost-effectiveness of contracting, similar in magnitude to the inefficiency created by hidden information

Title: A Theoretical Analysis of Special Safeguards
Abstract: Special safeguards for agriculture are WTO sanctioned tariffs triggered when imports for certain products exceed a predetermined threshold or when price falls below a predetermined floor. This policy tool emerged originally as part of the Uruguay Round Agreement of Agriculture for those nations that agreed to tarrification. A new, but similar special safeguard mechanism (SSM) has been proposed in the ongoing Doha Round for developing nations. The SSM has been highly contentious and commonly blamed for several breakdowns in negotiations. The purpose of this paper is to investigate theoretically the implications of quantity based special safeguards for agriculture in the presence of imperfect competition. The paper presents four models: one involving two foreign firms exporting to a nation without a domestic industry and three versions of a model with one domestic firm and one foreign exporter. Based on the market situation, the models show how foreign firms will try and lower imports in the current period to prevent triggering the tariff. We also document how firms can store imports in the pre-tariff period and sell in the post-tariff period and on what happens when the domestic firm is allowed to import from a third party.
