Study title

In the present data compilation the most important group indices of producer prices of agricultural products in form of long series with different base years will be presented in overviews for selected index positions. The index measures the development of selling prices in agriculture in domestic sales. The reference value of the overall index is the value of sales revenues in agriculture in the base year. In respect of the essential calculating process, the indices can be understood as a weighted average of price changes that are calculated for a representative selection of products and services. The price indices of agricultural products are calculated as the annual averages of the estimated average values on a quarterly basis of the goods with the corresponding quarterly sales in the current base year. The indices are calculated with the so called Laspeyres- formula. This means that the estimated numbers from the base year will be unchanged until the conversion of the indices into a new base year. The indices of the producer prices of agricultural products will not only be published as an overall index, but also for different levels of aggregation (product groups) and for single price representatives. In the present long term overviews only the aggregation concerning product types will be considered. Up to and including 1966/67 the reported indices include the betterment and/or sales tax. Since 1967 the index results appear twice in the publications of the federal statistical office; with and without the generalized betterment tax. In the present data compilation the indices in the tables of producer prices of agricultural products by the year of 1968 will be shown exclusively without betterment or sales tax and without upgrading compensation!
