CONTRACEPTION AND DEVELOPMENT: A UNIFIED GROWTH THEORY
研究现代避孕药具使用、生育率、教育与长期增长的相互作用，构建经济模型解释传统经济如何逐步转向使用现代避孕药具的高增长模式。
This study investigates the interaction of the use of modern contraceptives, fertility, education, and long‐run growth. It develops an economic model that takes into account that sexual intercourse is utility enhancing and that birth control by modern contraceptives is more efficient but more costly than traditional methods. The study shows how a traditional economy, in which modern contraceptives are not used, gradually converges toward a high growth regime, in which modern contraceptives are used. Lower prices or higher efficacy of contraceptives are conducive to an earlier onset of the fertility transition and a quicker takeoff to modern growth.
