요약This dissertation explores three enduring and controversial challenges in the U.S. agri-food system: misinformation, foreign farmland ownership, and food price inflation. Essay one examines how misinformation about food biotechnology affects consumers' food choices and proposes evidence-based countermeasures. Essay two investigates the drivers behind state-level legislative restrictions on foreign farmland ownership. Essay three analyzes how supply chain positioning relates to corporate financial performance amid recent economic shocks. Collectively, these studies offer a holistic view of the interdependent economic agents shaping the U.S. agri-food system and carry broad implications for its resilience and governance. Given that technological advancement, geopolitical conflicts, and inflationary pressures are persistent features of the global landscape, this dissertation provides a valuable foundation for future work to help agribusiness leaders, consumers, and policymakers make better-informed decisions during uncertain times.The first essay examines the effect of misinformation about genetically modified food on consumer demand and policy attitudes, and tests the effectiveness of pre-bunking and debunking mitigation strategies. While food biotechnology can contribute to agricultural sustainability and food security, prevalent misinformation risks enlarging the public-scientist knowledge gap and precluding the adoption of potentially beneficial technologies. Using data from a sample of 1,270 U.S. consumers, I find that exposure to misinformation has a significant effect on consumers' food choices and policy attitudes. I also find that pre-bunking is an effective mitigating strategy, while debunking by itself is not sufficient. This suggests that preemptively warning consumers about misinformation and the tactics used to spread it is more effective than merely correcting the misinformation afterwards. The second essay investigates the drivers of state-level legislative restrictions on foreign farmland ownership, a topic actively debated in the Congress and state legislatures. Foreign holdings of U.S. agricultural land have raised national and food security concerns, reflected in the growing amount of state legislative actions that seek to restrict foreign holdings of U.S. agricultural land in recent years. While there has not been clear evidence of the negative impacts of such foreign holdings, these restrictive legislations could lead to unintended economic consequences. Using uniquely constructed legislator- and state-level data, I find that while protecting state agricultural assets is part of the consideration, these state legislative actions are also responding to national security concerns raised by China-related incidents in recent years. The third essay explores how corporate profitability across U.S. agri-food supply chain segments responded to major economic shocks. U.S. retail food prices have surged rapidly to historic highs following COVID-19 and the Russia-Ukraine conflict, raising concerns about profit-driven inflation, although the evidence remains mixed. Because higher food prices can reduce affordability, identifying the key drivers of inflation is essential for designing effective policies. Using firm-level panel data of publicly listed companies from 2015 to 2024, I find heterogeneity in profitability across segments. I also find limited evidence of profit-driven food price inflation in the post-shock periods; overall, gross profits increased, but margins remained stable. Combined with analysis of corporate filings, the results suggest that rising costs and fiscal policies, rather than inflated markups, may be more important drivers of accelerating retail food prices.
