Abstract: The purpose is to employ a unique approach to assess the effects of climate change on US corn yields, emphasizing short-term and long-term impacts while quantifying adaptation. Leveraging a comprehensive dataset encompassing corn production and weather data, conventional assumptions are challenged by introducing time and county-varying coefficients that reveal the dynamic nature of adaptation. Findings indicate that past temperatures significantly shape farmers' expectations, influencing their adaptive strategies. Specifically, a negative impact of hot temperatures is identified, which diminishes in the presence of higher past temperatures, reflecting adaptation. The effects of a 2 C temperature increase are simulated, uncovering substantial short-term negative impacts that attenuate over the long term. It not only advances understanding of climate change adaptation in agriculture but offers valuable insights for policymakers addressing climate challenges in the agricultural sector.
