    2022 WAEA Presidential Address: Agricultural Trade Disputes

    Devadoss, Stephen
    24页
    查看更多>>摘要：Agricultural trade has been historically beset with a plethora of interventions by WTO member countries, which have led to numerous disputes. These trade disputes involve prolonged litigations and resolution processes, and during this time, trade barriers continue to exist. Furthermore, considerable resources are spent litigating these disputes which give rise to pervasive directly unproductive activities, resulting in significant inefficiencies and welfare loss. In this WAEA presidential address, I (i) review the WTO dispute settlement process, (ii) provide an up-to-date catalog of agriculture disputes, (iii) summarize major disputes involving the United States, (iv) present a detailed analysis of the US-China trade war, and (v) examine the benefits of global agricultural trade liberalization.

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

    Chen, BowenDennis, Elliott J.Featherstone, Allen M.
    25页
    查看更多>>摘要：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

    Gardner, GrantSampson, Gabriel S.
    21页
    查看更多>>摘要：We examine capitalization of ethanol plant construction and capacity expansion into surrounding irrigated and nonirrigated 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

    Tian, ZhengSchmidt, ClaudiaGoetz, Stephan J.
    31页
    查看更多>>摘要：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

    Devadoss, StephenUgwuanyi, BlessingRidley, William
    26页
    查看更多>>摘要：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

    Lee, JuheeHendricks, Nathan P.
    27页
    查看更多>>摘要：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

    Park, EunchunCoble, Keith H.Harri, Ardian
    33页
    查看更多>>摘要：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 premiums' 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.

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

    Burton, KatiMaas, AlexanderLee, Katherine
    23页
    查看更多>>摘要：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.
