Patterns of State Productivity Growth in the U.S. Farm Sector: Linking State and Aggregate Models
研究美国农业部门及各州的全要素生产率增长，发现全国平稳增长掩盖了州际差异，且总量增长完全由各州趋势驱动，州际资源转移影响很小。
Abstract This article focuses on agricultural productivity growth at both sector and state levels. It does so in a way that preserves the economic integrity of national and state production accounts. A model accounting for interstate transactions in farm goods links sectorwide and state‐specific measures of total factor productivity growth. An interesting conclusion is that the smooth, persistently positive trend typically observed for farm sector productivity growth masks considerable variation across states and regions. The results also indicate that farm sector productivity growth is wholly a function of productivity trends in the individual states. Interstate shifts in production activity and resource reallocations have had little impact.
