A Simple Measure of β‐Convergence
提出一个不受高尔顿谬误影响的β收敛简单度量，并用1950-1988年OECD数据验证，发现β收敛仅在σ收敛存在时成立。
We propose a simple measure of β‐convergence which is not subject to Galton's fallacy. We illustrate our measure with OECD data for the period 1950–1988. We find evidence of β‐convergence but only in the presence of σ‐convergence.
