Population growth and poverty: Another look at the Indian time series data
研究了印度农村贫困的时间趋势，发现贫困不仅受人均农业产出影响，还独立受人口规模影响，且这种关系与通常假设显著不同。
Previous studies of the time trend of rural poverty in India agree in assuming that population size does not influence poverty independently of per capita agricultural output. The article examines this assumption for the 1959/160 to 1970/71 period using a pooled model with variable slope coefficients to avoid the problem of collinearity between population estimates and time. The results suggest that poverty in India during 1960s was a function of both agricultural production and population, but that the properties of this function are significantly different from those generally posited.
