When Michigan corn farmer chooses to invest in irrigation or drought-tolerant seeds, they're making a deeply personal calculation about risk—one that researchers at the University of Illinois Urbana-Champaign and Michigan State University have now mapped out in surprising detail.
As extreme weather becomes the new normal, farmers across the American heartland face a question with no perfect answer: how much uncertainty can they afford to absorb? A new study published in the Journal of the Agricultural and Applied Economics Association reveals that Michigan farmers respond to climate risk in wildly different ways, and understanding those differences could reshape how policymakers design support programs.
Lead researcher Natalie Loduca, a clinical assistant professor in the Department of Agricultural and Consumer Economics at the University of Illinois, partnered with Scott Swinton, professor emeritus of agricultural economics at Michigan State University, to survey corn and soybean farmers across Michigan. Working with Michigan State University Extension, they recruited producers operating at least 300 acres who relied on farming as a major source of income—the backbone of the region's agricultural economy.
The researchers used a clever economic tool: choice experiments that asked farmers to make decisions under uncertainty. First, participants evaluated fictional monetary lotteries—scenarios where they could choose between high risk with high potential reward or lower risk with modest returns. Then came the crucial part: the same questions reframed through the lens of actual farming decisions. Each scenario presented choices about a 40-acre corn field: invest in drainage, irrigation, drought-tolerant seeds, or crop insurance, or take no action at all. Each choice carried different consequences for expected revenue and exposure to weather-driven yield loss.
The results proved revealing. Across both the general financial lotteries and the agriculture-specific scenarios, farmers showed themselves to be fundamentally risk-averse. But here's what matters for policy: their attitudes toward uncertainty shifted dramatically depending on context. In the farming scenarios, risk preferences varied far more widely than in the abstract financial choices. Some farmers proved willing to invest substantially in adaptive technologies; others showed markedly higher tolerance for taking their chances with the weather.
"The findings have implications for policymakers," Loduca said. "Given the wide range of risk preferences across farmers, different types of programs or policies could be targeted to each group." That insight cuts to the heart of an agricultural policy paradox: a one-size-fits-all approach to climate adaptation leaves money on the table. More risk-averse farmers gravitate toward protective investments in technologies that reduce climate-driven yield risk. Those with higher risk tolerance may respond to entirely different incentives—suggesting that effective climate policy requires understanding not just what farmers face, but how they think about the future.
Loduca and Swinton are now pursuing deeper work, linking these measured risk preferences to farmers' actual decisions about future investments and adoption strategies. The long-term goal is to understand what truly drives these choices. In a region where agriculture remains vital to the economy and climate uncertainty continues to mount, that knowledge could prove invaluable—the difference between policies that farmers embrace and those they quietly ignore.
