Testing Long‐Run Productivity Models for the Canadian and U.S. Agricultural Sectors
通过分离性约束检验了总产出与净产出生产率指数背后的生产结构，基于美国和加拿大农业部门的超越对数生产函数数据，支持总产出全要素生产率结构，但拒绝了净产出希克斯中性假设。
Abstract The primary objective of this paper is to develop the linkages between the gross and net productivity indexes and the implied production structures. These linkages are developed as separability restrictions on various subgroups of inputs and time in a general production model. The restricted models are arranged in sequences for nested hypotheses testing. Empirical evidence from the U.S. and Canadian agricultural sectors based on a translog production function support the gross output total factor productivity structure. The net output Hicks neutrality hypothesis is rejected for both the United States and Canada.
