The primary goal of the present study is to use cross-national data on labor-force structure to examine the manner in which the international system shapes the character of national development, and the consequences of variation in development strategy for the growth and the distribution of national income. A complementary goal is to illustrate the use of residual plots to overcome the "black box" character of cross-national studies, and thereby provide a bridge to case-study research. Multivariate analyses and residual plots provide results congruent with both world-political-economy and developmental perspectives, and indicate that the world economy may be used by lesser developed countries to obtain more rapid and equitable economic growth, although this was not a natural outcome of the world economy in the 1960s and 1970s.
