REASSESSING THE IMPACT OF BARRIERS TO CAPITAL ACCUMULATION ON INTERNATIONAL INCOME DIFFERENCES*
重新审视了资本积累障碍对人均GDP差异的影响，发现其影响被夸大，但消除障碍能显著改变劳动力在传统与现代部门间的就业份额，从而解释发展过程中劳动力转移的典型事实。
Can barriers to capital accumulation account for large differences in GDP per capita? We reconsider the claim that these barriers have an amplified effect on income levels in a model where both modern and traditional sector technologies are active. We show that this claim is not correct. We do find, however, that the removal of barriers to capital accumulation can cause large changes in the employment shares of labor. Thus the model can account for an important stylized fact of the development process, with labor moving from the traditional to the modern sector as income levels rise.
