Nonhomotheticity and Technological Bias in Production
提出一种估计非齐次CES生产函数中非齐次性与技术偏向的方法，并应用于1970-74年墨西哥、巴西、哥伦比亚及四个中美洲国家七个行业的横截面企业数据，发现六个行业存在正的非齐次性，且考虑非齐次性后技术偏向并非主要为资本使用型。
This paper develops an approach to estimating nonhomotheticity and technological bias within the class of nonhomothetic CES production functions. The model is applied to cross-section firm level data covering seven industries in Mexico, Brazil, Colombia, and four Central American countries for the period 1970-74. Positive nonhomotheticity (higher capital intensity for larger plant size given factor price ratios) is found in six industries. Other results are that, once nonhomotheticity is accounted for, technological bias is not predominantly capitalusing, and equality of capital intensity between transnational and domestic firms is pervasive.
