The Sensitivity of Labor Demand Functions to Choice of Dependent Variable
检验劳动力需求函数的参数是否对不同的估计方法敏感，利用1970和1980年美国人口普查数据发现估计结果相当稳健。
This paper investigates whether the parameters of labor demand functions are sensitive to alternative methods of estimation.The assumption that the production technology is of the Generalized Leontief type implies that the demand system can be estimated by analyzing cross-section differences in earnings across labor markets, by studying longitudinal changes in earnings within a labor market, or by investigating cross-section differences in labor force participation rates across labor markets.The estimation of these models on the 1970 and 1980 Public Use Samples from the U.S. Census reveals that the estimates of labor demand functions are indeed quite robust to major specification changes.
