A New Approach to Estimating Production Function Parameters: The Elusive Capital–Labor Substitution Elasticity
生产函数参数估计的新方法:难以确定的资本—劳动替代弹性
Parameters of taste and technology are central to a wide variety of economic models and issues. This article proposes a simple method for estimating production function parameters from panel data, with a particular focus on the elasticity of substitution between capital and labor. Elasticity estimates have varied widely, and a consensus estimate remains elusive. Our estimation strategy exploits long-run variation and thus avoids several pitfalls, including…
