Book Description
These essays study important causes and interactions of agricultural policy and food demand. Essay one identifies the pattern of wheat support and income over historical data. The results indicate that income has statistically significant effects on wheat support, the pattern is nonlinear and varies among support mechanisms, and this relationship permits estimation of the future support. Essay two examines the effect of China wheat stock policies in 2006-2013 on the market using a structural economic model. Simulation results suggest that government stock policies stabilized wheat market prices, if measured by the standard deviation, and raised production in China. Essay three applies fixed effect and demand system models to estimate how refrigerator ownership affects food consumption in rural China. Refrigerator ownership reduces total food expenditure and meat consumption quantity, according to the estimation results, and might increase the expenditure share of perishable foods, like meat, egg and seafood. Taken as a whole, the results suggest that scientists should consider the impact of expanding refrigerator ownership, recognize the potential effect of public stocks on the evolution of price, and include the income-to-support relationship in long-run analysis to generate more accurate projections of consumption, price volatility, and agricultural support.

Book Description
This dissertation analyzes the empirical implications of selected policies and regulations applied to agricultural and food markets in the United States. It focuses on the policies at the regional level where the role of government influences the dynamics of agricultural markets and consumer behavior. In the first essay, in Chapter 2, I examine how regulation affects household diversity-seeking behavior for alcohol. Here I hypothesize that different state-level regulatory regimes in alcohol retail sales impact shopping convenience. I use a consumer panel dataset to examine household purchases of alcohol between 2004 and 2016. By focusing on a subset of households that moved between regulatory regimes in the pooled cross-sectional dataset, I am able to treat the time-invariant regulatory rules as a natural experiment to identify the causal impact of grocery store sales of alcohol on consumer choice diversification. The key finding suggests consumers further diversify their product selections in states that allow alcohol sales in grocery stores which reduces consumer's shopping costs and increases convenience. In the second essay, in Chapter 3, I focus on the effects of crop insurance on the supply of specialty crops in the United States. I use a nationally-representative farm-level dataset to evaluate the impacts of crop insurance on the acreage and crop value of fruits and vegetables. The empirical strategy addresses the potential endogeneity between the provision of crop insurance and the economic significance of the crops. In assessing how the availability of crop insurance affects supply, I use a number of variables to instrument insurance availability for fruits and vegetables. Instruments include i) the number of policies sold and premium subsidies for field crops within the same county, ii) the number of policies sold and premium subsidies for fruits and vegetable crops in the neighboring counties, which characterize various degrees of insurance demand. The two-stage findings suggest that crop insurance has increased both the harvested acreage and production value of fruits and vegetables. In the final essay, presented in Chapter 4, I worked with a team to evaluate several risk management strategies for cherry growers facing crop losses due to spring frost and excessive summer rain. Here we developed a framework to model stochastic prices, yields, and revenue for sweet cherries in New York and Michigan in a Monte Carlo simulation framework. This research constructed a novel dataset comprised of state-level market information for sweet cherries, station-level weather data, and the monitored performance of high tunnel at horticultural trials from research farms. Our results show that when there are significant price premiums for early season fruit, a high tunnel system could be the optimal strategy as it has the capacity to generate higher net profits compared to a variety of alternative strategies using insurance products.

Book Description
Robust and vibrant agricultural markets are an important component of inclusive agriculture-led economic development. Governments of developing countries play an important role in fostering an enabling environment for agricultural markets to thrive and in addressing shortcomings arising due to incomplete agricultural markets. However, excessive government involvement can also lead to inefficiencies and can further obstruct the development of agricultural markets. This dissertation focuses on various agricultural market outcomes and evaluates them in light of government interventions that potentially have a direct or indirect effect on them.The first essay investigates whether and how liquidity constraints during the production period affect smallholders' market participation and choice of marketing channel in the context of the Zambian maize market. During the period of the study, the country's parastatal marketing board 0́3 the Food Reserve Agency (FRA) 0́3 operated alongside private buyers and purchased large volumes of maize at a pan-territorial price that exceeded average market prices. Results indicate that liquidity-constrained maize-growing smallholders produced less maize output, were less likely to sell maize, and were less likely to sell to the FRA, as compared to those that did not face liquidity constraints. These results imply that benefits of market policies like those of the FRA are likely to be disproportionately captured by relatively wealthier and less resource constrained farmers.The second essay focusses on the effects of various regulations imposed on international trade and the domestic fertilizer market on fertilizer imports - an important component of domestic fertilizer supply in most developing countries. The results indicate that increased time and/or costs needed to comply with border regulations (such as clearing customs and inspections) are associated with a decline in the volume of fertilizer imported. However, fertilizer market-specific regulations are not found to be statistically significantly associated with fertilizer imports. Further investigation reveals that the border regulation-related findings hold mainly for high and middle-income countries, plausibly due to poor enforcement of formal laws and the greater importance of informal rules in the markets of low-income countries.The third essay explores whether price uncertainty (a form of price volatility) affects the price levels of maize products in urban Zambia, in light of the highly discretionary and ad-hoc government interventions in the country's maize markets. Excessive price volatility of staple food products has adverse effects on food and nutritional security of vulnerable populations and can potentially disrupt the development of resilient food markets. I conduct a Vector Autoregressive-Generalized Autoregressive Conditional Heteroscedastic (1,1)-in-mean (VAR-GARCH(1,1)-in-mean) analysis of monthly price data for four maize products: wholesale maize grain, retail maize grain, and two types of maize flour 0́3 breakfast meal (highly refined) and roller meal (less refined). I find some weak evidence that an increase in uncertainty in wholesale maize grain prices is associated with a small increase in own prices, although this result does not hold across all specifications. Price uncertainty of other products is not found to be associated with changes in prices of own or other products. The application of VAR-GARCH(1,1)-in-mean to model prices of food products across a value chain is a methodological improvement over existing studies in this area in a developing country context.

Book Description
Motivated by recent food price spikes, this thesis examines three issues relating to international prices of agricultural commodities. It focuses on the three most important food commodities in the world from a calorie viewpoint, namely wheat, rice and maize. Following the introductory chapter, Chapter 2 presents an overview of the determinants of agricultural commodity prices. Chapter 3 analyses political economy causes of trade policy interventions in response to commodity price spikes to reveal why governments alter trade interventions in order to cushion domestic prices from external shocks. To examine how much countries insulate their domestic markets from international markets, Chapter 4 estimates price transmission elasticities for wheat, rice and maize by employing a novel estimation approach. The first essay (Chapter 2) probes demand and supply shocks in global grain markets. Using annual data from 1961 to 2012, price fluctuations for wheat, rice and maize are decomposed into three components: supply shocks, demand shocks and other shocks. The ""other shocks"" here include policy responses of some governments, such as export restrictions and panic purchases when prices spike upwards. The chapter estimates how much each of these shocks contributed to the evolution of grain prices during the last half century. The results suggest that supply and demand shocks have contributed very little to price fluctuations, compared to other shocks. The other shocks seem to have exacerbated exogenous price rises due to a supply shortfall, particularly in periods when prices spike. The second essay (Chapter 3) studies the implications of reference dependence and loss aversion features of individual preferences in trade policy determination and shows that these behavioural features help explain why governments change their trade restrictiveness in order to cushion domestic prices from international price shocks. We show that this change comes irrespective of whether special interest groups are lobbying the government. Using a global dataset on agricultural price distortions, we find the available empirical evidence is consistent with our model predictions. The empirical evidence further suggests that governments' reactions to international prices are stronger for staple food items than for non-staples. A voluminous literature has estimated price transmission from international to domestic markets, ignoring unobserved common factors that affect all domestic markets. In the third essay (Chapter 4), this thesis estimates long-run and short-run transmission elasticities of world commodity price shocks to domestic markets using a framework that takes into consideration common factors that are correlated with regressors. The estimates are based on an annual panel dataset for rice, wheat and maize for both developed and developing countries over the period 1960-2007. The results from the common factor framework are compared to those that do not account for common factors. The findings suggest price transmission elasticities for rice, wheat and maize are around 0.4, 0.5 and 0.75 respectively. The findings suggest that ignoring common factors is likely to result in upwardly biased estimates of price transmission elasticities. The final chapter of the thesis (Chapter 5) contains a summary of the findings of the three main chapters in the thesis.

Book Description
"In the first essay of my dissertation, I examine how agricultural support affects the design of preferential trade agreements (PTAs). I hypothesize that democratic institutions that over-represent rural interests create incentives for leaders to negotiate flexible trade agreements to respond to the concerns of their agricultural constituents. To validate this argument, I construct a measure of flexibility using a Bayesian item response theory that treats flexibility as a latent characteristic of trade agreements. With this index and panel data covering 648 PTAs signed from 1948-2017, I find that political leaders are more likely to introduce flexibility provisions when entering into trade agreements as they confer more agricultural subsidies to farmers. Instrumental variables regression indicates that most of the effect of agricultural subsidies on flexibility provisions is attributable to rural malapportionment. In the second essay, I study which firm-level factors influence government's decisions to protect firms from increased import in the United States. After opening up domestic markets for more competition by making PTAs, the government seeks to protect "losers of trade" by providing financial assistance or imposing tariffs against competitors. Using a novel firm-level data I gathered, I find that firms' corporate political activity plays an important role in receiving government assistance and tariff protection. In addition, focusing on firms' geographic location, I find that firms located in US counties in which incumbent politicians lose the vote share in the last presidential election are more likely to receive the supports from government. The results imply that firm lobbying and geopolitical location influence government's trade protection policy. In the final essay, I consider the role of third parties in the WTO dispute settlement process and investigate how they contribute to the legalization of the WTO. Using an original dataset, covering all WTO disputes from 1995 to 2012, I find that third parties have heterogeneous motivations for participation and have different effects on dispute settlement and compliance. In particular, third parties that claim to have "systemic interests" help to accelerate dispute resolution and make respondents more likely to comply with rulings"--Pages viii-ix.
