    Measuring Price Elasticities of Demand and Supply of Water Entitlements Based on Stated and Revealed Preference Data (2015)
    Oxford University Press
    Details
    Publication Date: 2015-12-13
    Description: Estimates of price elasticities of water entitlements (known as permanent water or water rights in the United States) are complicated by data limitations and problems of endogeneity. To overcome these issues, we develop an approach to generate stated preference data and combine them with revealed preference data to estimate price elasticities from various types of water entitlement sales in the southern Murray-Darling Basin, Australia. Our results suggest that price elasticities of demand and supply of high security water entitlements are inelastic in the relevant market price range between AUD ${{\$}}$ 1,700 to ${{\$}}$ 2,100 per mega-liter, and that supply is relatively more inelastic than demand. For lower reliability water entitlements, the price elasticity of demand is estimated to be even more inelastic than high security water entitlements. The price elasticity of supply for general security water entitlements is similar to high security water entitlements, while the supply of low reliability water entitlements is extremely inelastic for our data set. The comparison between the stated and revealed preference data provides strong evidence of support for a data fusion approach; nevertheless, some differences in water sale preferences were found for irrigators choosing not to sell all of their water. The consistency of our results signals support for the use of this methodology in other water basins around the world.

    Why Do Fewer Agricultural Workers Migrate Now? (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-18
    Description: The share of agricultural workers who migrate within the United States has fallen by approximately 60% since the late 1990s. To explain this decline in the migration rate, we estimate annual migration-choice models using data from the National Agricultural Workers Survey for 1989–2009. On average, over the last decade of the sample, one-third of the fall in the migration rate was due to changes in the demographic composition of the workforce, while two-thirds was due to changes in coefficients ("structural" change). In some years, demographic changes were responsible for half of the overall change.

    Endogeneity Corrected Stochastic Production Frontier and Technical Efficiency (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-18
    Description: A major econometric issue in estimating production parameters and technical efficiency is the possibility that some forces influencing production are only observed by the firm and not by the econometrician. Not only can this misspecification lead to a biased inference on the output elasticity of inputs, but it also provides a faulty measure of technical efficiency. We extend the Levinsohn and Petrin (2003) approach and provide an estimation algorithm to overcome the problem of endogenous input choice in stochastic production frontier estimation by generating consistent estimates of production parameters and technical efficiency. We apply the proposed method to a plant-level panel dataset from the Colombian food manufacturing sector for the period 1982–1998. This dataset provides the value of output and prices charged for each product, expenditures, and prices paid for each material used, energy consumption in kilowatt per hour and energy prices, number of workers and payroll, and book values of capital stock. Empirical results find that the traditional stochastic production frontier tends to underestimate the output elasticity of capital and firm-level technical efficiency. The evidence in this research suggests that addressing the endogeneity issue matters in stochastic production frontier analysis.

    Model Choice and Size Distribution: A Bayequentist Approach (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-18
    Description: We propose a new three-step model-selection framework for size distributions in empirical data. It generalizes a recent frequentist plausibility-of-fit analysis (step 1) and combines it with a relative ranking based on the Bayesian Akaike information criterion (step 2). We enhance these statistical criteria with the additional criterion of microfoundation (step 3), which is to select the size distribution that comes with a dynamic micromodel of size dynamics. A numerical performance test of step 1 shows that our generalization is able to correctly rule out the distribution hypotheses unjustified by the data at hand. We then illustrate our approach and demonstrate its usefulness with a sample of commercial cattle farms in Namibia. In conclusion, the framework proposed here has the potential to reconcile the ongoing debate about size distribution models in empirical data, the two most prominent of which are the Pareto and the log-normal distribution.

    To Bid or Not to Bid: The Role of Participation Rates in Conservation Auction Outcomes (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-10
    Description: In this article, I jointly analyze stated willingness to accept values with revealed auction bids from fishing license buybacks in the Chesapeake Bay blue crab fishery in order to better understand the link between participation decisions and conservation outcomes. In contrast with theoretical expectations, I find individuals with the lowest willingness to accept participated in these reverse auctions at lower rates than other eligible individuals, all else being equal. This suggests that who bids in an auction plays an important role in the success of conservation outcomes. These results indicate that market design should expand to consider how, and whether, the economic incentives underlying auction participation align with desired conservation outcomes, both within fisheries and in natural resource management more broadly.

    A Triple-Hurdle Model of Production and Market Participation in Kenya's Dairy Market (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-10
    Description: Existing analyses of market participation are based on a "double-hurdle" modeling approach. Such models are appropriate only when all members of the population of interest actually produce the good. In some contexts, however (e.g., smallholder farmers), many members of the population do not produce particular goods that they could produce and that their neighbors do produce. Policies influencing market participation among producers may thus also induce additional farmers to become producers. Previous double-hurdle approaches do not allow explicitly for this possibility. To address these limitations, this article presents a "triple-hurdle" approach with an initial stage that includes nonproducers. The model is used to identify the factors associated with Kenyan smallholder farmers choosing to participate in dairy production, and the role that these producers choose to play (or not) in the marketplace. In the midst of debates underway over the privatization of the parastatal Kenya Creameries Company, new knowledge about smallholder participation in dairy could be an important contribution. Results suggest the importance of rural electrification, training, and improved grazing practices. We find that expected net sales are significantly higher when farmers have access to informal private markets. We also describe a version of the ordered tobit model that includes nonproducers and is nested in our triple-hurdle model. A likelihood ratio test shows the latter to be a significantly better fit to our data. We discuss how insights gained from this study differ from the insights that would come from a double-hurdle ordered tobit that also includes nonproducers.

    Substitutes or Complements? Consumer Preference for Local and Organic Food Attributes (2015)
    Oxford University Press
    Details
    Publication Date: 2015-07-10
    Description: This research examines consumer preference and compares their willingness-to-pay for a host of value-added attributes of processed blackberry jam, and focuses on various organic and local production location designations. Instead of being treated as a binary attribute, three levels of USDA organic are considered: 100% organic, at least 95% organic, and made with organic ingredients (at least 70% organic). For local production, three levels are also included in the analysis: cross-state region (the Ohio Valley), state boundary (state-proud logos), as well as sub-state regions. Stated-preference data collected from a choice experiment in a mail survey in Kentucky and Ohio are used. Results from the study confirm positive willingness-to-pay for both organic and local attributes. However, consumers were willing to pay comparatively more for jam produced locally in regions smaller than the border of a state compared to organic jam. Furthermore, substitution and complementary effects between food attributes were investigated. The study found strong substitution effects between organic and local production claims, an issue that has thus far received minimal treatment in the existing literature on organic and local food willingness-to-pay studies. The results indicate a large degree of overlapping values in the willingness-to-pay for these two food attributes. In addition, the "small farm" attribute considered in the study also appears to be a substitute for organic and local attributes, which confirms the previous belief that one of the many reasons consumers purchase organic or local products is to support small or family-owned farms.

    Asia-Pacific Integration with China versus the United States: Examining Trade Patterns under Heterogeneous Agricultural Sectors (2015)
    Oxford University Press
    Details
    Publication Date: 2015-09-12
    Description: This article examines bilateral trade patterns in the Asia-Pacific using a new model in which comparative advantage within the agricultural sector is linked to agro-ecological characteristics, and trade costs are product-specific. Bilateral market share is a function of productivity and trade costs. However, countries with similar land and climate characteristics systematically have high productivity in similar products making them disproportionately sensitive to changes in each other's trade costs. We use a random coefficients logit model to estimate a parametric distribution of comparative advantage and trade costs across products and calculate regional trade liberalization elasticities for each exporter in each import market. Unlike most existing models, the value of the elasticity depends on the degree to which liberalization includes competitors with similar comparative advantage within the agricultural sector. We find disproportionately larger trade elasticities under China-led liberalization relative to U.S.-led liberalization among close U.S. competitors compared to countries whose agricultural products are unlikely to compete head-to-head with U.S. exports. For the United States, we find that the "lost opportunity" cost of exclusion from regional liberalization is increasing in the extent to which its close competitors gain new access.

    Long-run and Global R&D Funding Trajectories: The U.S. Farm Bill in a Changing Context (2015)
    Oxford University Press
    Details
    Publication Date: 2015-09-12
    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.
