Effects of Risk Attitude and Risk Perceptions on Risk Management Decisions: Evidence from Farmers in an Emerging Economy

By: Khanal, Aditya R. ; Mishra, Ashok K. ; Lien, Gudbrand
Using primary survey data of onion growers in India, this study tests the relationship between and predictability of risk attitude measures on farmersÕ risk management decisions. We find that farmers with high risk aversion are more likely to adopt farm diversification strategies, good agricultural practices, government-recommended seed varieties, and preventive measures against diseases and pests than farmers with low risk aversion. The likelihood of farmers adopting good agricultural practices decreases with perceived higher risks of low-quality production, a higher risk of losing crops due to weather, and insects and pests.

Price Dynamics, the Law of One Price, and Quantile Regressions

By: Santeramo, Fabio G.
The Law of One Price is a dated but still puzzling economic concept. Studies have found that violations of the law are frequent and numerous, although scholars have pointed that these failures are likely to be due to a lack of informative datasets. In addition, for storable commodities, the possible interactions of spatial and temporal arbitrage may hide the implications of the law, invalidating the conclusions of the studies. Based on a simplified two-market model of spatiotemporal arbitrage, I review the implications of the Law of One Price and test for them with a rich dataset of weekly prices of storable commodities and information on transaction costs, trade, and storage. I conclude that most statements implied by the Law of One Price are not empirically violated.

Purebred Nellore Prices in Brazil: Morphological, Genetic, Physical, and Market Factors in Auctions

By: Calil, Yuri Clements Daglia ; Ribera, Luis A. ; Anderson, David P. ; Koury Filho, William
The Nellore breed is the cornerstone of BrazilÕs successful beef production. However, Nellore seedstock pricing has yet to be understood. We performed a hedonic analysis under a hierarchical model to explore how physical, morphological, genetic, and market factors affect the prices of purebred animals sold at auctions. The findings indicated that visual scores, expected progeny differences, farm reputation, and auction type explain variations in prices. In addition, the morphological index brought higher premiums than the genetic index. The results have implications for farmers, genetic improvement programs, and policymakers as they indicate relevant factors in the seedstock cattle price formation process.

Weather Impacts the Agricultural Production Efficiency of Wheat: The Importance of Precipitation Shocks

By: Chen, Bowen ; Dennis, Elliott J. ; Featherstone, Allen M.
Many studies have explored the determinants of technical efficiency in crop production, but fewer have examined how weather might change technical efficiency over time. We estimate weather effects on technical efficiency using data from 540 Kansas winter wheat farms from 2007/08 to 2016/17 using a panel stochastic frontier model that controls for farm-specific heterogeneity with farm fixed effects. Results show that precipitation is nonlinearly related to technical efficiency and that extreme temperature is associated with lower technical efficiency. Improving resilience to precipitation shocks is key to sustained efficient wheat production in Kansas.

Land Value Impacts of Ethanol Market Expansion by Irrigation Status

By: Gardner, Grant ; Sampson, Gabriel S.
We examine capitalization of ethanol plant construction and capacity expansion into surrounding irrigated and non-irrigated farmland values using data on every land transaction in Kansas from 1995 to 2017 in a hedonic price model. We hypothesize that corn prices and thus land values are higher near ethanol plants. We further hypothesize that ethanol market expansion is capitalized into irrigated parcels to a greater extent than into nonirrigated parcels due to differences in water demand and precipitation. We estimate that an irrigated (nonirrigated) parcel within 50 km of an ethanol plant experiences an average price premium of 8.8% (6.3%) relative to more distant parcels.

The Role of Community Food Services in Reducing US Food Insufficiency in the COVID-19 Pandemic

By: Tian, Zheng ; Schmidt, Claudia ; Goetz, Stephan J.
We use state-level Census Household Pulse Survey data to examine the role of community food services such as food banks and pantries in reducing food insufficiency during the COVID-19 pandemic in the United States. Food insufficiency increased for all income classes during the pandemic, and especially for the lower and middle classes. We adopt a fixed effects filtered estimator to estimate the coefficients on time-invariant regressors in a fixed effects panel model. Estimation results suggest community food services contribute to mitigating food insufficiency, especially for the middle class and in the early months of the pandemic.

Determinants of Global Agricultural Trade

By: Devadoss, Stephen ; Ugwuanyi, Blessing ; Ridley. William
While comparative advantage factors expand agricultural trade, trade and domestic policies and gravity factors can either promote or hinder commodity trade. We use a theoretical multicountry trade model to analyze how various factors impact agricultural trade. Following previous literature, we model cross-country productivity differences using a probabilistic distribution. We then empirically implement the theoretical model to quantify the effects of various determinants of agricultural trade. Production-inhibiting policies and tariffs hinder bilateral trade, while domestic institutional quality, support programs, and land endowments expand bilateral trade.

Irrigation Decisions in Response to Groundwater Salinity in Kansas

By: Lee, Juhee ; Hendricks, Nathan P.
Understanding the interaction between groundwater salinity and irrigation decision making has important implications for groundwater management. Econometrics models were estimated using observed farmer behavior in response to different groundwater salinity levels in a region of Kansas. Estimation results demonstrate that farmers in the face of groundwater salinity change their irrigation decisions on irrigated acreage (i.e., extensive margin), crop choice (i.e., indirect intensive margin), and water application depth (i.e., direct intensive margin). The empirical results indicate an overall decrease in water use due to higher salinity, primarily through a decrease at the extensive margin.

Estimating Crop Yield Densities for Counties with Missing Data

By: Park, Eunchun ; Harri, Ardian ; Coble, Keith H.
Crop yield densities are often estimated at the county level. However, county-level yield data providers often omit county records due to low participation or other reasons. The data omission can undermine insurance premiumsÕ credibility and thereby lead to restrictions on the provision of area insurance products in specific locations. To address this problem, we propose a novel Bayesian spatial interpolation method to estimate crop yield densities for counties with missing data. Empirical results indicate that our approach is consistently superior to the benchmark approaches. Importantly, our approach offers noticeable estimation accuracy even at a significant level of data omission.

An Empirical Evaluation of Tobacco Addiction in the United States

By: Hovhannisyan, Vardges ; Bastian, Chris ; Devadoss, Stephen
This study adopts a novel approach to assessing addiction to cigarettes, small and large cigars, e-cigarettes, smokeless tobacco, and loose smoking tobacco by decomposing tobacco demand into supernumerary and precommitted quantities. Supernumerary tobacco consumption represents a demand component that varies with prices and smoker income, while precommitted consumption is immune to changes in economic circumstances and thus may be reflective of addiction. By empirically estimating the supernumerary and precommitted demand components, we shed light on the severity of tobacco addiction and smoker price and income responsiveness in the United States, which may prove vital in refining various tobacco control policies.

Impacts of Bilateral Trade Agreements between the United States and Latin American Countries on Agri-Food Trade

By: Luckstead, Jeff
Between 2004 and 2012, the United States enacted bilateral trade agreements with Chile, Peru, Panama, and Colombia. Using bilateral trade panel datasets of agri-food commodities, we estimate a structural gravity model to analyze the trade creation and trade diversion effects of these agreements. The agreements resulted in substantial increases in intramember trade for aggregate agri-food trade among member countries, ranging from 53.73% for the Chilean agreement to 354.03% for the Peruvian agreement. Substantial heterogeneity exists when the aggregate commodity is disaggregated and when US exports to and imports from the four Latin American countries are considered.

A Case Study in Contamination: Persistent Home Value Losses Associated with the Elk River Spill

By: Burton, Kati ; Maas, Alexander ; Lee, Katherine
This study quantifies the magnitude and spatial-temporal persistence of home value losses associated with a chemical spill in the Elk River using difference-in-difference, spatial regression techniques. Results suggest homes within 3 miles of the spill experienced a value loss, with the largest effect on homes within one mile of the spill. Homes beyond 3 miles experienced no significant effect. The loss in value affected prices for years after the contamination was remediated. Homes within the water utility service area experienced a significant increase in value following the spill, which may reflect public value of water quality monitoring by a utility.
