US federal farm payments and farm size: Quantile estimation on panel data
利用受限面板数据的分位数估计，研究美国联邦农业补贴对玉米/大豆和小麦生产者农场规模的影响，发现补贴与农场规模正相关，但未证实补贴仅使大农场扩大或大农场增长更快。
Abstract The marginal effect of government payments on farm size of US corn/soy and wheat producers is currently contested. This paper uses a quantile estimator with a restricted access panel dataset. Payments are positively associated with farm size; the association is statistically significant at select percentiles of the farm size distribution, but the statistical significance is not systematically related to farm size. Although the marginal effect is qualitatively larger for bigger farms, their differences are not statistically significant. This study does not provide any empirical evidence to suggest that federal farm dollars cause (i) only large farms to grow bigger or (ii) large farms to grow more than small farms.
