The impact of exchange rate fluctuations on profit margins: The UK car market, 1971-2002

Abstract

We investigate the impact on profit margins of exchange rate fluctuations in order to examine optimal pricing policy by source countries in the UK car market. We first estimate a nested logit demand model of new cars to calculate model-specific profit margins. Next we use these estimates to analyse the pricing-to-market (PTM) behaviour of car importers and local producers. The results show that: (1) profit margins fell over the period 1971-2002 as the UK car market moved from being a concentrated market to a looser oligopoly structure: (2) there is a positive association between exchange rate changes and mark-up adjustments of imported cars. Following a 10% pound depreciation, exporters' profit margins declined by up to 4% and local producers' profit margins increased by up to 2%; (3) PTM behaviour is asymmetric between appreciations and depreciations in bilateral exchange rates.
