Convergence? Inferences from Theoretical Models
指出趋同争议部分源于对增长理论可检验假说的不同理解，论证新古典增长范式不仅产生条件趋同假说，也产生俱乐部趋同假说，并说明引入人力资本、收入分配等变量后俱乐部趋同假说更具竞争力。
This essay suggests that the convergence controversy may reflect, in part, differences in perception regarding the viable set of competing testable hypotheses generated by existing growth theories. It argues that in contrast to the prevailing wisdom, the traditional neoclassical growth paradigm generates the club convergence hypothesis as well as the conditional convergence hypothesis. Furthermore, the inclusion of empirically significant variables such as human capital, income distribution,and fertility in conventional growth model, along with capital markets imperfections, externalities, and non-convexities, strengthens the viability of club convergence as a competing hypothesis with conditional convergence.
