Endogenous Growth and Cross-Country Income Differences
构建了一个多国熊彼特增长模型，分析研发国家与非研发国家的增长路径差异，发现研发国家收敛于平行增长路径而其他国家停滞，并探讨了参数变化对相对生产率和世界增长率的影响。
A multicountry Schumpeterian growth model is constructed. Because of technology transfer, R&D-performing countries converge to parallel growth paths; other countries stagnate. A parameter change that would have raised a country's growth rate in standard Schumpeterian theory will permanently raise its productivity and per capita income relative to other countries and raise the world growth rate. Transitional dynamics are analyzed for each country and for the world economy. Steady-state income differences obey the same equation as in neoclassical theory, but since R&D is positively correlated with investment rates, capital accumulation accounts for less than estimated by neoclassical theory.
