ABSTRACT
The argument of the previous chapter suggests that new entry into West African trade may be difficult because capital requirements are often heavy and because there appear to be certain definite though limited economies of size. These forces, together with the advantages accruing from an early start, tend to bring about a measure of concentration. This in turn tends to perpetuate the strength of the large firms by conferring on them certain advantages which impede and inhibit the entry of new firms and the growth of smaller firms.
