Daniel Sumner on the Political Economy of Agriculture

Episode Summary

Executive Summary: Russ Roberts and Daniel Sumner trace the evolution of U.S. farm policy from New Deal price supports and government stockpiling to today’s subsidy-heavy risk-management system. They emphasize that programs often favor large, capitalized farms, distort incentives, and persist mainly because of politics, historical inertia, and effective coalition-building—not because they are economically compelling.

Main Topics: Origins of U.S. farm subsidies in the New Deal (Priority: 5/5): Sumner explains that major federal farm programs began during the Great Depression to raise farm prices, support struggling farmers, and stabilize agricultural markets through legislated prices, supply controls, and government purchases. Price supports, stockpiles, and supply management (Priority: 5/5): The discussion covers how the government raised prices by law, bought commodities, stored them through the Commodity Credit Corporation, and sometimes reduced supply by idling land or destroying products like pigs and milk. Political economy and distributional winners/losers (Priority: 5/5): The speakers examine who benefited most: large farms, landowners, and politically organized commodity groups, versus taxpayers and consumers who paid higher taxes or prices. Transition from price supports to direct payments and crop insurance (Priority: 5/5): Sumner describes the shift from visible price supports and deficiency payments to more opaque direct payments, shallow-loss programs, and heavily subsidized crop insurance and dairy margin protection. Industry consolidation, productivity growth, and technology (Priority: 4/5): They discuss how agriculture became far more productive and consolidated over time, with fewer farmers producing far more output, and how managerial talent and scale helped shape modern farming. Politics, lobbying, and coalition formation (Priority: 5/5): Sumner argues that commodity groups, not scattered farmers, drive policy outcomes by organizing effectively; sugar, dairy, cotton, and corn are contrasted with less coordinated sectors like cattle. International effects and trade disputes (Priority: 4/5): The conversation addresses how U.S. subsidies and export programs affect world prices and foreign producers, including the WTO cotton case and the impact of U.S. policies on global markets.

Key Arguments: New Deal farm programs were designed to raise prices and incomes during the Depression, but they quickly created surplus, storage, and market-distortion problems. Government attempts to set minimum prices for commodities increased production while reducing private demand, forcing the state to buy, store, or destroy output. These programs disproportionately benefited larger farms and landowners because subsidies raise the value of land, the most inelastic resource in agriculture. Modern farm support shifted from open-ended stockpiling to direct payments, then to subsidized insurance and revenue protection, making transfers less visible but still substantial. Crop insurance subsidies and shallow-loss programs now function as the main vehicle for support, with taxpayers covering much of the premium and backstop losses. Agricultural policy persists less because it is efficient than because it is entrenched, historically familiar, and defended by organized commodity coalitions. U.S. subsidies can affect global commodity prices, sometimes harming foreign producers; the cotton case is a prominent example where WTO rulings found U.S. support distorted world prices. Farm consolidation and productivity growth were driven mainly by technology, management, and market forces, not by subsidies alone, though policy interacted with these trends. Commodity groups succeed politically when they can present a unified voice and mobilize thousands of members, while fragmented industries struggle to secure comparable treatment.

Data Points: Start of major U.S. farm programs: New Deal era (1930s) - Sumner says modern federal agricultural subsidies began during Roosevelt’s response to the Great Depression. Parity base period: 1910-1914 - Congress used this period as the benchmark for setting parity prices for farm products. Common support crops: Corn, wheat, soybeans, cotton, rice - These major field crops were covered by price support and supply-control programs. Other supported sectors: Dairy, tobacco, peanuts - These commodities had distinct marketing orders or quota systems. 2014 milk policy change: Spring 2014 - Sumner says the federal milk price support program and export subsidy were finally eliminated. Transition to current-era farm policy: 1980s onward - Farm policy began moving away from price supports and toward market-based and insurance-style support. Current annual support level: $15-20 billion - Sumner estimates the annual taxpayer cost of modern farm support and insurance programs. Covered farm revenue: About $300 billion - He says this is the scale of farm revenue protected by current programs. Share of farm revenue supported: 6%-10% - Approximate proportion of farm revenue covered by subsidies and insurance. WTO cotton compensation: About $150 million per year for about five years - The U.S. paid Brazilian cotton farmers while resolving the cotton subsidy dispute. Cotton subsidy share of revenue: About half - At the time of the WTO case, U.S. cotton farmers received roughly half their revenue from federal checks. Cotton price comparison: World price $0.35 vs U.S. equivalent $0.70 - Illustrates how subsidies raised the effective revenue received by U.S. cotton producers. Agriculture employment/scale change: From about 10 million farming families to a few hundred thousand full-time farmers - Sumner describes the long-run consolidation and shrinking number of farm operators. Part-time/family farming: About 1 million to 1.5 million families - He notes many more households farm as a side activity or retirement pursuit.

Pivotal Quotes: "the curious task of economics is to demonstrate to men how little they really know about what they imagine they can design." — Russ Roberts: Used to frame the unintended consequences and complexity of farm policy design. "It's my job to keep it that way." — Norfleet Sugg (recounted by Daniel Sumner): A vivid anecdote about how opaque the peanut program is and how specialists preserve that complexity. "we've always had these things so long people are really uneasy turning them off." — Daniel Sumner: Sumner’s explanation for why farm subsidies persist despite weak economic arguments.

Implications: Farm policy is now less about visible price supports and more about hidden insurance subsidies and coalition politics. Expect continued support unless reform overcomes entrenched interests, historical habits, and the difficulty of organizing diffuse taxpayers against concentrated beneficiaries.
