export promotion has been more successful than import substitution because it relies on specialization and
comparative advantage.

SOLUTIONS TO PROBLEMS APPENDIX
1. (Worlds Apart) Per capita income most recently was about 160 times greater in the United
States than in the Democratic Republic of the Congo. Suppose per capita grows an average of 3
percent per year in the richest country and 6 percent per year in the poorer country. Assuming
such growth rates continue indefinitely into the future, how many years would it take before per
capita in the Congo exceeds that of the United States? (To simplify the math, suppose at the
outset per capita income is $160,000 in the richer country and $1,000 in the poorer country.)
To solve this problem, you must be able to use the compound growth function on a personal
2. (Why Incomes Differ) What factors help workers in high-income economies become more
productive than those in other economies?
Labor productivity, measured in terms of output per worker, is by definition low in low-
income countries, as it depends on the quality of the labor and other inputs that combine with
