CONCENTRATION, MARKETING ARRANGEMENTS AND COMPETITION (I)
In earlier chapters it has been shown that by the middle of the I 930's one firm together with its subsidiaries and affiliates handled about onethird of the external trade of West Africa, while some five or six firms were responsible for about three-fifths of the total. In standardized staple imports and in the principal export products the concentration was appreciably larger. Moreover, groups of the largest firms frequently acted in concert. There were comprehensive market-sharing agreements in the purchase of the principal export crops and in the sale of imported merchandise.
