  • Food Abundance and Violent Conflict in Africa
    • Authors: Koren O.
      Pages: 981 - 1006
      Abstract: Scholars debate whether climate change has a consistent effect on the likelihood of armed conflict in Africa. One major pathway by which climatic variability is hypothesized to increase conflict is by decreasing food availability. However, limitations on food access at both the local and national levels in many developing African countries force most armed groups and communities to depend on locally-produced food. These actors are therefore likely to use violence to establish control over more food resources or be stationed where more food is available, suggesting that food abundance might also be driving conflict. The present study employs novel data on wheat and maize yields in Africa measured at the very local level to empirically evaluate this hypothesis on a highly disaggregated conflict indicator. To account for the endogenous relationship between conflict and food production, average local levels of drought are used as an instrument. The findings show that, contrary to previous expectations, conflict is driven by higher yields, on average, and not by scarcity.

  • Comment on “Food Abundance and Violent Conflict in Africa”
    • Authors: Burke M.
      Pages: 1007 - 1009
      Abstract: Scholars and writers have long noted a link between the physical environment and how humans behave toward one another. In Shakespeare’s Romeo and Juliet, Benvolio tells Mercutio that they should retreat indoors because the heat of the day makes it more likely that a fight will break out; they fail to do so and many die. In Camus’ The Stranger, Mersault becomes too hot while on a beach and shoots a man. And writing a century ago in the Quarterly Journal of Economics, Huntington (1917) argues that climatic shifts in the Mediterranean in the centuries around the birth of Christ led to declining agricultural productivity and the eventual violent fall of the Roman Empire.

  • Food Abundance and Violent Conflict in Africa: Response to Marshall
           Burke’s Comments
    • Authors: Koren O.
      Pages: 1010 - 1011
      Abstract: In his comments on my article, Marshall Burke highlights the valid issue of effect size. First, note that as the reference points are very small given the number of annual grid cells and the rarity of conflict cases across all cells, the average number of annual cell-level conflicts is only 0.228, which ensures that a prediction of even one conflict per cell-year corresponds to an increase of ∼439% from the baseline average conflict level across all cells. Hence, a 1,500% increase means a substantive increase of approximately 3.42 incidents. With that in mind, this note offers three possible explanations in response to Burke’s critique.

  • Agricultural Extension and Technology Adoption for Food Security: Evidence
           from Uganda*
    • Authors: Pan Y; Smith S, Sulaiman M.
      Pages: 1012 - 1031
      Abstract: We evaluate causal impacts of a large-scale agricultural extension program for smallholder women farmers on technology adoption and food security in Uganda through a regression discontinuity design that exploits an arbitrary distance-to-branch threshold for village program eligibility. We find eligible farmers used better basic cultivation methods, achieved improved food security. Given minimal changes in adoption of relatively expensive inputs, we attribute these gains to improved cultivation methods that require low upfront monetary investment. Farmers also modified their shock-coping methods. These results highlight the role of information and training in boosting agricultural productivity among poor farmers and, indirectly, improving food security.

  • The Impact of Cash and Food Transfers: Evidence from a Randomized
           Intervention in Niger
    • Authors: Hoddinott J; Sandström S, Upton J.
      Pages: 1032 - 1049
      Abstract: We contribute to debates regarding the use of cash and in-kind transfers by providing new evidence from a very low income setting, rural Niger. We motivate our findings through the use of a conceptual model that emphasizes that the impact of cash and food transfers on dimensions of food consumption—both quantity and quality—will differ by the income level of the household and whether or not the food transfer is extra-marginal. Consistent with this model, households in localities randomized to receive the food basket experienced larger, positive impacts on measures of dietary diversity than those receiving the cash transfer. By contrast, households receiving cash were more likely to make bulk purchases of grains and spent more money on private transfers and debts. Despite the seasonal dimensions to food insecurity in Niger, the relative impact of food and cash transfers on our measures of dietary diversity did not vary markedly by season.

      Pages: 1050 - 1071
      Abstract: Farmers throughout the United States report a shortage of workers. At the same time, there are proposals to strengthen the enforcement of existing immigration laws. In this paper, we develop an equilibrium approach to examine the impact of removing undocumented workers from the California agricultural labor market, and to infer whether there is evidence of shortages using individual-worker data. We find evidence that is consistent with a persistent shortage in some sub-sectors of the California farm labor market. Further, we conduct counter-factual policy simulations over a range of possible policy alternatives, and find that removing 50% all undocumented farm workers from the state would lead to an increase in wages of over 22%.

  • A Century of U.S. Farm Productivity Growth: A Surge Then a Slowdown
    • Authors: Andersen M; Alston J, Pardey P, et al.
      Pages: 1072 - 1090
      Abstract: U.S. farm productivity growth has direct consequences for sustainably feeding the world’s still rapidly growing population, as well as U.S. competitiveness in international markets. Using a newly expanded compilation of multifactor productivity (MFP) estimates and associated partial-factor productivity (PFP) measures, we examine changes in the pattern of U.S. agricultural productivity growth over the past century and more. Considering the evidence as a whole, we detect sizable and significant slowdowns in the rate of productivity growth in recent decades. U.S. multifactor productivity grew at an annual average rate of just 1.16% per year during 1990–2007 compared with 1.42% per year for the period 1910–2007. U.S. yields of major crops grew at an annual average rate of 1.17% per year for 1990–2009 compared with 1.81% per year for 1936–1990. More subtly, but with potentially profound implications, the relatively high rates of MFP growth during the third quarter of the century are an historical aberration relative to the long-run trend.

  • A Parametric Estimation of Total Factor Productivity and Its Components in
           U.S. Agriculture
    • Authors: Plastina A; Lence S.
      Pages: 1091 - 1119
      Abstract: The present study aims at improving our understanding of the individual contribution of the components of total factor productivity (TFP) change to U.S. agricultural productivity. A novel sequential primal-dual estimation routine to calculate TFP change is proposed, using a multi-output input distance function in the first stage, followed by a cost minimization routine in the second stage. TFP change is estimated as the direct sum of the estimates of technical change, technical efficiency change, allocative efficiency change, input price effects, changes in output markup, and changes in returns to scale in each state. The validity of the proposed methodology is supported by the remarkable overlap and high correlation of our annual estimates of TFP change with the USDA’s measures of change in TFP by state. Although technical change tends to be the largest contributor to productivity change, it bears a low and statistically insignificant correlation with TFP change on an annual basis, whereas annual changes in the markup effect and returns to scale are highly and significantly correlated with TFP changes. This is the first study to find a slowdown of technical progress in the U.S. farm sector in the 1990s and 2000s, and technical regress during the farm crisis of the 1980s. While technical efficiency shows a positive overall trend, allocative efficiency shows a negative overall trend, and their combined effect (i.e., the overall cost efficiency) slows down TFP growth. The policy recommendations from previous studies on the drivers of TFP should be revised in light of these findings.

  • Producer Decision Making under Uncertainty: Role of Past Experiences and
           Question Framing
    • Authors: Tonsor G.
      Pages: 1120 - 1135
      Abstract: Limited research examines the role of reference points or how uncertain outcomes are processed in producer decisions. This study employs a survey containing a split-sample choice experiment varying how uncertain outcomes are portrayed, and assesses multiple candidate reference points. Results suggest that U.S. cattle producers use the best outcome experienced as reference points in their decisions, and the method by which uncertain outcomes are presented impacts loss aversion, marginal willingness to pay, and market participation estimates. This illustrates how research employing split samples, multiple reference points, and alternative methods of portraying uncertain outcomes may better identify producer decision-making.

  • Has Resistance Taken Root in U.S. Corn Fields' Demand for Insect
    • Authors: Wechsler S; Smith D.
      Pages: 1136 - 1150
      Abstract: Corn farmers reported unexpectedly severe damage on fields planted with genetically-engineered rootworm-resistant (Bt-CRW) corn seeds during the 2009 growing season. Entomologists later determined that rootworms on these fields had developed resistance to the insecticidal proteins produced by Bt-CRW corn. This article explores what corn farmers’ seed and soil insecticide choices imply about rootworm resistance in the United States. First, a soil insecticide demand function is derived using a damage-abatement model. Next, this demand function is estimated using field-level data from 2005 and 2010. We find that rootworms (Diabrotica spp.) cost farmers approximately $1.3 billion in 2005 and $2 billion in 2010. When used, Bt-CRW seeds were very effective, reducing average yield losses by approximately five bushels per acre and providing over twice as much control (on average) as soil insecticides. We found no evidence that soil insecticide use was higher on fields where resistance was most likely to develop. However, we did find that demand for soil insecticides was elastic. These results suggest that rootworm resistance was not widespread in 2010, but that it could substantively increase soil insecticide use if it evolved and spread.

  • USDA Announcement Effects in Real-Time
    • Authors: Adjemian M; Irwin S.
      Pages: 1151 - 1171
      Abstract: In 2012, the Chicago Board of Trade eliminated a morning trading halt that coincided with the normal publication time for important USDA commodity reports. Previously, market participants had hours of halted trading time to review the information in the reports and adjust their strategies in advance of market re-opening. We use 2009–2014 intraday grain futures market price and volume data to show that, without a trading halt, ensuing real-time trading on USDA crop announcements exhibits noticeable volatility spikes in agricultural futures markets, but that this heightened volatility dissipates within the space of a few trading minutes. In addition, continuously-traded markets appear to have a more difficult time distinguishing between the newsworthiness of government reports. Nevertheless, continuously traded crop markets take nearly the same time to fully absorb these shocks, following a very similar time path. Re-imposing a timeout would necessarily lengthen the price discovery process.

  • Efficient Estimation of Risk Preferences
    • Authors: Wu F; Guan Z.
      Pages: 1172 - 1185
      Abstract: Risk and the risk attitude of agents are two fundamental elements of decision making under risk and uncertainty. Recent developments in risk and risk preference analyses have raised questions on conventional approaches to estimating risk preferences. This study proposes an estimation procedure that employs a seminonparametric estimator to estimate the density function of risk without imposing distributional assumptions, as well as a numerical integration method to construct closed-form expressions of conditional moment conditions for efficient estimation. The method achieves a substantial efficiency improvement relative to the conventional GMM approach in Monte Carlo simulations. The proposed approach is general and applies to the estimation of behavioral choice models under risk, or models that require expectation operations and closed-form equations for estimation.

  • Understanding Hypothetical Bias: An Enhanced Meta-Analysis
    • Authors: Penn J Hu W.
      Pages: 1186 - 1206
      Abstract: The presence of hypothetical bias (HB) associated with stated preference methods has garnered frequent attention in the broad literature trying to describe and understand human behavior, often seen in environmental valuation, marketing studies, transportation choices, medical research, and others. This study presents an updated meta-analysis to explore the source of HB and methods to mitigate it. While previous meta-analysis on this topic often involves a few dozen articles, this analysis includes 131 studies after reviewing over 500 published and unpublished articles. This enables the inclusion of several important factors that have not been investigated before. These include relatively recent willingness to pay elicitation methods such as choice experiments and the Turnbull lower bound estimator. Newly emerged HB reduction techniques such as consequentiality and certainty follow-up treatments are also included. For explanatory variables that have been examined in previous studies, this analysis does not always report consistent findings. In particular, holding everything constant and contrary to commonly-held beliefs, the method of auction does not offer much reduction to HB compared to more conventional methods such as a referendum vote. However, choice experiment, cheap talk, consequentiality and certainty follow-up all significantly contributed to explaining and mitigating the magnitude of HB. These results help practitioners to understand HB’s presence and choose appropriate methods for amelioration. The framework established through this study also enables future analyses targeted at understanding variations built upon one or multiple HB mitigation techniques.

  • Teachers and Urban-Rural Gaps in Educational Outcomes
    • Authors: Zhang J; Jin S, Torero M, et al.
      Pages: 1207 - 1223
      Abstract: We examine the role of teachers in explaining the urban-rural gap in educational outcomes. Using a large panel data set of students and teachers collected from China and explicitly controlling for the endogeneity of prior student academic achievement, we find that the urban-rural difference in teacher effects contributes in large part to the observed urban-rural gap in student academic achievement. In other words, if rural teachers were of the same quality as urban teachers, the urban-rural gap in student academic achievement would be reduced substantially.

  • Financial Capability and Food Security in Extremely Vulnerable Households
    • Authors: Millimet D; McDonough I, Fomby T.
      Pages: 1224 - 1249
      Abstract: Food insecurity is among the most significant, nutrition-related public health issues facing the United States. Unfortunately, little is known about the determinants of food insecurity except that it is not synonymous with poverty. Many households above the poverty line are food insecure; many below are not. We investigate a lack of financial capability as a potential salient determinant of household-level food security. Using original survey data collected among food pantry clients in North Texas, we assess the impact of financial capacity on food security relying on family background as an exclusion restriction. Our results indicate a strikingly significant effect, both economically and statistically, of financial capability in general and financial behaviors in particular.
