This paper addresses the empirical analysis of wholesale profit margin
s using data of the Dutch wholesale sector, 1986. At the heart of the
analysis is the typical nature of wholesale production: wholesalers do
not produce a tangible product, but offer a service capacity. This ha
s an immediate impact on the identification, interpretation and measur
ement of determinants of profit variations. A model is set up to expla
in variations in wholesale profit margins, which is inspired by two wi
dely applied approaches to industry pricing: the behavioural mark-up m
odel and the marginalist price-cost model.
