Earnings differentials between public, private and joint sectors in Punjab (India)
利用1975-76年旁遮普家庭收支调查数据，估计扩展人力资本模型，发现公共部门平均工资高于私人和合资部门，并分解了收入差异的来源。
Using the data collected by the Economic and Statistical Organisation of Government of Punjab under the survey ‘The Working Class Family Income and Expenditure in Punjab, 1975–76’, we estimated the expanded version of the human capital model. On the average public sector workers are paid much higher wages than the private and joint sector workers. In the first part of the article, we have estimated the earnings equation for the workers of public, private and joint sectors separately. In the second part, we have decomposed the difference between the average earnings of public and joint sector workers into two parts ‐ the portion that exists due to the difference in endowments and personal characteristics of the workers of different sectors, and the portion that exists due to the difference in pay structures of different sectors.
