The decision of an important car manufacturer to open a factory in another country may result in an increase in the -ex- port of tyres from the country in which the parent car firm is operating and an increase in the import of tyres in the country in which the branch car factory has been established, although no real change in the volume of trade in tyres has resulted. Thus the sudden rise in French exports of tyres to England in 1926 was in part due to the establishment in England in that year of branch works of the Citroén car company. Michelin sup- plied the main Citroén works in France from its French factory and continued to supply the first equipment to Citroén cars manu- factured in England. As, however, Citroén cars had previously been arriving in England fitted with Michelin tyres, the additional exports of tyres from France to England, resulting from the change in place of delivery did not represent any true increase in the French export trade in tyres. Changes in the practice of shipping cars with or without tyres may have similar effects on the trade returns. 27. In a different category come the variations in the trade re- surns caused by changes in stocks arising either from changes in the agencies of distribution or from changes in car design. 28. The imminence of a tariff duty or an alteration in the rate of tariff may also temporarily affect the flow of exports and im- ports. Large shipments of tyres from the United States arrived in the United Kingdom too late to enter duty free when duties on tyres were imposed, in 1927, in the United Kingdom. These iyres were transferred to the Irish Free State which at that time was a free market. The imports of the Irish Free State were therefore temporarily inflated. 29. Statistics of values of the exports of tyres are also affected in varying degree according to the extent to which the tyres ex- ported are shipped in fulfilment of ** first equipment '’ orders. ** First equipment ’’ orders are important to tyre manufacturers, not only for the advertisement they afford, but as providing large running orders. It is customary therefore to supply *‘ first equip- ment *’ orders at prices below those for replacement. The differ- ence between the two scales of prices is probably greater in the United Kingdom and in the United States than in France. Where car manufacturers have established assembly plants in other coun- ries, the tyre manufacturer which supplies the parent company with *‘ first equipment *’ frequently holds the contract for supply- ing the foreign branch, either at the price charged for first equip- ment in the country of origin or at the lowest rate prevailing for first equipment business in the country in which the assembly works are situated. As first equipment prices are below those for replacement, the recorded value of exports from a country which is making large shipments for first equipment, will appear Effect of sranch factories on national trade statistics.
