    Predicting the Effects of Sugar-Sweetened Beverage Taxes on Food and Beverage Demand in a Large Demand System (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: A censored Exact Affine Stone Index incomplete demand system is estimated for 23 packaged foods and beverages and a numéraire good. Instrumental variables are used to control for endogenous prices. A half-cent per ounce increase in sugar-sweetened beverage prices is predicted to reduce total calories from the 23 foods and beverages but increase sodium and fat intakes as a result of product substitution. The predicted decline in calories is larger for low-income households than for high-income households, although welfare loss is also higher for low-income households. Neglecting price endogeneity or estimating a conditional demand model significantly overestimates the calorie reduction.

    The System of Rice Intensification and its Impacts on Household Income and Child Schooling: Evidence from Rural Indonesia (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: The yield potential of a set of improved rice management practices, known as the System of Rice Intensification (SRI), has attracted much attention. Yet we know surprisingly little about SRI's socio-economic impact. Using data from Indonesia in 2009, this study assesses the impact of SRI on household incomes and child schooling. We find that SRI generates significant estimated yield gains. However, because SRI induces a reallocation of family labor from non-farm to farm, SRI users enjoy no household income gains. Despite the increased labor demand for farming, we find no evidence that SRI has a child labor effect.

    Do Neighborhood Parks and Playgrounds Reduce Childhood Obesity? (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: Using the 2007 National Survey of Children's Health data, we find a statistically and economically significant effect of neighborhood parks and playgrounds on childhood obesity based on covariate matching estimators. The park/playground effect depends on gender, age, race, household income, neighborhood safety, and other neighborhood amenities. The results suggest that adding a neighborhood park/playground may reduce the obesity rate and make children more fit, but relevant interventions must consider socioeconomic status of the targeted children as well as other neighborhood amenities.

    The Impact of Immigration Enforcement on the U.S. Farming Sector (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: We examine the effects of local immigration enforcement efforts on U.S. agriculture in dozens of U.S. counties from 2002–2010 by using variations in the timing of adoption of 287(g) programs, which permit local police to enforce immigration law. Difference-in-differences models using microdata from the American Community Survey (2005–2010 waves) and county tabulations from the Census of Agriculture (1997, 2002, and 2007) yield robust evidence that county enforcement efforts have reduced immigrant presence in adopting jurisdictions. We also find evidence that wages of farm workers, patterns of farm labor use, output choices, and farm profitability may have been affected in a manner consistent with farm labor shortages.

    Neighbors and Extension Agents in Ethiopia: Who Matters More for Technology Adoption? (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: The increased adoption of fertilizer and improved seeds are two key aspects to raising the level of land productivity in Ethiopian agriculture. However, the adoption and diffusion of such technologies has been slow. We use data from Ethiopia between 1999–2009 to examine the role of learning from extension agents versus learning from neighbors for both improved seeds and fertilizer adoption. We combine farmers' spatial networks with panel data to identify these influences, and find that while the initial impact of extension agents was high, the effect wore off after some time, in contrast to learning from neighbors.

    Econometric Analysis of Grading Standards: The Ordered Fractional Approach (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: We present a method for estimating the quality of production when quality is measured by discrete grades and is thus both ordinal and fractional. Monte Carlo experiments indicate that our method estimates average partial effects of quality determinants more accurately than linear estimators, and provides estimates with low bias even with weak instruments. An application of the model to wheat production in Japan demonstrates the importance of disease control in determining wheat grade. Weather variable coefficients suggest that climate change could actually improve wheat quality in Japan, thereby allowing farmers to reduce fungicide use and other inputs, as well as switch varieties.

    Does the Jack of All Trades Hold the Winning Hand? Comparing the Role of Specialized versus General Skills in the Returns to an Agricultural Degree (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: This paper examines the roles of specialized versus general skills in explaining variation in the returns to an agriculture degree among graduates working both inside and outside the agricultural industry. The focus on returns by sector of employment is motivated by our finding that most agricultural graduates are employed in non-agricultural jobs. In that study, a sample of alumni graduating from a large Midwestern public university between 1982 and 2006 shows that alumni with majors more specialized in agriculture earned a premium from working in the agriculture industry, but this advantage has diminished over time. Agricultural graduates with more general training earn more outside than inside agriculture. Higher-ability graduates in more industry-focused curricula tend to sort into the agricultural industry, while higher-ability graduates in broader curricula tend to choose jobs outside of agriculture. All graduates are more likely to accept agricultural employment when the farm economy is strong, but agricultural graduates who enter agricultural jobs when the farm economy is weak suffer lifetime earnings reductions. These findings suggest that greater levels of specialization may limit a graduate's ability to adjust to changing economic circumstances. Agriculture degree programs could benefit from curriculum innovations that focus on developing more generalized skills.

    Is the Shale Energy Boom a Bust for Nearby Residents? Evidence from Housing Values in Pennsylvania (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: Profitable extraction of previously inaccessible shale energy reserves has led to the rapid expansion of shale exploration across the United States. We present one of the first empirical studies to measure the impact of early shale exploration on surrounding homeowners using data from Washington County, Pennsylvania, from 2008 to mid 2010. We find that property values are negatively impacted by shale gas exploration activity, but this impact depends on the proximity and intensity of shale activity and is largely transitory. The negative effects are larger for households located close to major highways and sourced with private well water.

    A Natural Resource Theory of U.S. Crop Insurance Contract Choice (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: A large variety of subsidized crop insurance products are available to U.S. crop growers. Distinct and perhaps puzzling patterns in the choices of insurance products and coverage levels can be discerned. Where production conditions are better and yields are less risky then ( a ) higher insurance coverage levels are chosen; and ( b ) revenue insurance is preferred over yield insurance. Also, ( c ) the extent of preference for revenue insurance is stronger in more productive areas. Assuming, as many do, that growers seek to maximize subsidy transfers, point ( a ) can be explained by the interaction between yield technology and natural resource endowments. Points ( b ) and ( c ) can be explained by location in conjunction with the "natural hedge" and a contract design bias in how revenue insurance guarantees are computed. Empirical study of Risk Management Agency data on corn, soybean, and wheat yields, and insurance contract choices lend support to our model inferences.

    Information Transmission in Irrigation Technology Adoption and Diffusion: Social Learning, Extension Services, and Spatial Effects (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-22
    Description: In this article, we investigate the role of information transmission in promoting agricultural technology adoption and diffusion through extension services and social learning. We develop a theoretical model of technology adoption and diffusion, which we then empirically apply, using duration analysis, on a micro-dataset consisting of recall data covering the period 1994–2004 for olive-producing farms from Crete, Greece. Our findings suggest that both extension services and social learning are strong determinants of technology adoption and diffusion, while the effectiveness of each of the two informational channels is enhanced by the presence of the other.
