Is Being Bold Better? Industry Expectations of USDA Corn and Soybean Production Estimates
Despite the extensive use of industry expectations in measuring forecast accuracy and price reactions to USDA reports, very little is known about their properties beyond the basic statistical characteristics of bias, rationality, efficiency, and relative accuracy. Using unique proprietary data of firm-level expectations for upcoming USDA corn and soybean production estimates, we demonstrate that these forecasts exhibit cognitive biases such as attribution and anchoring. Prior success leads to overconfidence and bolder forecasts, and firms base their forecasts on a known reference value. We also show that the bolder the forecasts, the lesser the accuracy, indicating that substantially deviating from the herd does not pay off when it comes to crop production forecasts.
期刊介绍:
Agricultural Economics aims to disseminate the most important research results and policy analyses in our discipline, from all regions of the world. Topical coverage ranges from consumption and nutrition to land use and the environment, at every scale of analysis from households to markets and the macro-economy. Applicable methodologies include econometric estimation and statistical hypothesis testing, optimization and simulation models, descriptive reviews and policy analyses. We particularly encourage submission of empirical work that can be replicated and tested by others.
