Online price data provide a new and rich source of information. But in the absence of information on quantities or on expenditure, researchers average prices and price behaviour across all products within a product group. In doing so, they introduce significant measurement error and potential bias. In this paper we address this challenge by presenting a simple methodological innovation that allows researchers to obtain information on expenditure when expenditure is not known. Specifically, we argue that measures of retail distribution – which can be computed solely from prices – provide a good proxy for expenditure.

Through a series of simulations that use scanner-level price and quantity information on about 85% of the Fast Moving Consumer Goods (FMCGs) sold in the GCC countries, we show that treating all products equally introduces substantial measurement error and bias in the calculation of price stickiness, of inflation, and of international price differences. But we also show that adding information on retail distribution reduces measurement error by 71%, 73%, and 75%, in the above estimations, respectively.  Our findings also have important implications for the work of the International Comparison Program (ICP).
