Wage Gap Between Formal and Informal Regular Workers in India: Evidence from the National Sample Survey

Abstract

This article elucidates the wage differential between formal and informal workers across different sectors, gender, occupation, and industry by using the 61st (2004–2005) and 68th (2011–2012) Rounds of National Sample Survey Office (NSSO) unit-level data. The study emphasizes two things: first, identifying the existence of the absolute wage gap between formal and informal workers and, second, finding the intensity of discrimination in wage between formal and informal workers. The vast body of literature available on this issue identifies gender, caste, religion, and region as the factors causing wage discrimination. This literature makes a shift from these traditional concepts by explaining the importance of job contract as a basis of wage discrimination.

This study utilizes the percentage relative gap (PGR) to work out the absolute wage gap between the two types of workers (formal and informal) and thereafter decomposes it to arrive at the source of the wage gap. The study applies the threefold Blinder–Oaxaca (B–O) decomposition method, which categorizes the total wage gap into three parts. The dependent variable chosen for the equation is the natural logarithm of daily wage. While the wage gap between formal and informal workers did not significantly fall during the study period, the results, on the other hand, indicate that the component of discrimination is larger than the component of endowment. This explains the discrimination perpetrated against informal workers in the Indian labor market. Tackling such discrimination necessitates implementation of more proactive policies for achieving wage equality in India.
