Surviving Variable Yields And Prices, Kara Zimmerman, Cory Walters, Jessica Groskopf, Matt Stockton, Kate Brooks

Cornhusker Economics

A marketing strategy focusing on prices from the most re-cent past, indirectly gives little or no weight to all of the other possible price outcomes. While it is intuitive that the most recent prices are more likely to play a role in our decision-making process, there are other price events that can happen. The seasonal price path from the 2019/2020 crop year was nothing like we have recently experienced. Sup-pose we entered the 2020’s marketing decision using a seasonal approach that considers only the average price series over the past 5 years (2015-19 average), Figure 1. The seasonal average indicates …
