Producer Price Indexes for Petroleum Refining
A Producer Price Index (PPI) for an industry measures price changes received by domestic establishments for the industry's output sold outside the industry. PPIs reflect the price trends of a constant set of goods that together represent the total output of an industry. When an establishment is asked to participate in the PPI survey, it is ...Web
