National policies and the sectoral pattern of economic growth
检验了用于解释各国人均GDP增长的国家政策变量，能否同样解释发展中国家农业和非农业部门的人均增长，发现农业收敛更慢、人口负担更重，且正统经济政策对农业增长的解释力弱。
Abstract This article presents tests of whether the kinds of “national” policy variables used to explain cross‐country variation in the growth of aggregate GDP per capita can also successfully explain per capita growth in the agricultural and nonagricultural sectors of developing countries. There are four main results of interest. First, relative to nonagriculture, convergence is much slower in agriculture and the burden of population growth is generally much higher. Second, while orthodox economic policies share positive associations with economic growth in the nonagricultural sectors of developing countries, such policies fail to robustly predict variation in agricultural growth. Third, size of government indicators often yield an “unexpected” positive association with agricultural growth. And finally, although there is some evidence that fewer price controls are associated with faster agricultural growth, these associations are statistically quite weak and quantitatively quite small.
