The present paper may bP considered as a step in the application
of the latter alternative. Its limited scope permitted but a
censory survey of the possible determinants of comparative
advantages, and it may be usefully followed by more detailed
investigations. It would appear desirable to explore the principal
influences determining trade flows in more detail and one may
also wish to examine the stability of the trade performance
indices, the effects of changes in relative prices on these indices,
or the relationship between the level of technological development
and Comparative advantage.
