Abstract
All national post offices offer an extensive range of mail products to customers. It is likely that the various demand elasticities of these products differ across services (for example, products grow at different rates in response to economic growth or are more or less responsive to a given price change) and that there is some degree of substitutability between at least some products. It is also the case that the impact on volumes from developments such as electronic substitution and competitive entry may vary across services. Consequently, it is important to have an understanding of the demand for mail products at a disaggregated level. There are various approaches that, in principle, could be adopted to gain such understanding but, where data are available, one which is well suited at a relatively high level of aggregation is econometric modelling using time series data.
