The United States Department of Agriculture's National Agricultural Statistics Service (NASS) conducts hundreds of surveys each year on topics related to the U.S. agricultural industry. One important set of data published by NASS is the Prices Received and Prices Paid Index Series. These index series, as mandated by legislation, provide a measure of the general level of price change compared to a base reference period for agricultural commodities sold and farm inputs purchased by farmers. This Selected Poster outlines future price index methodology research questions NASS will be working on. Special attention is devoted to the role of the price relative estimator. Example index calculations for the Feed Grain Prices Received Index are provided using three different price relative estimators.
