An analysis of U.S. aggregate output response by farm size
研究美国不同规模农场的供给弹性是否随规模变化，发现小农场比中型农场对价格反应更敏感，否定了供给弹性与规模无关的假设。
Past empirical evidence on supply response by size of farm in the U.S.A. provides no clear basis to conclude that supply elasticities vary systematically with farm size. In this paper, the central hypothesis that no systematic relationship exists between production response to price and size of farm is rejected. U.S. farms are disaggregated into nine economic size categories and own-price supply elasticities are measured for per farm and total agricultural output. Empirical results from this study suggest that supply response does vary systematically by farm size, with smaller farms exhibiting greater elasticities than midsized farms.
