Developed countries are the dominant trading partner.
Since trade must influence a bigger economy, its effect is less than that for a dev eloping economy. The logic here is that as GNP per capita decreases, more pressure is placed on the common, public infrastructure, thus causing it to wear out faster. GNP that is reinvested back into the infrastructure each year. The curve is nonlinear, indicating that investment falls off fairly linearly until the economy completely collapses at low GNP per capita levels. Fraction of the population that dies each year, which is assumed to depend on GNP per capita.
