Contract labour and firm growth in India

In the late 1940s, the new Indian nation, fearful of the job losses if large British companies were to leave India, passed a law that made it illegal for large companies to downsize.  It is likely that this law, which became known as the Industrial Disputes Act (IDA), was successful in ameliorating the immediate crisis in the late 1940s. But it is also likely that it distorted incentives for Indian entrepreneurs. Who would want to invest if one was stuck paying workers that are no longer needed if the investment turned out to be unsuccessful?

There is considerable evidence that the IDA did in fact have a powerful disincentive effect. First, the Indian manufacturing sector is characterised by a large number of informal firms, a small number of large firms, and a high marginal product of labour in large firms. Second, while US manufacturing firms typically grow by a factor of eight over three decades, the typical manufacturing firm in India does not grow at all over its life cycle.2 These facts suggest that something like the IDA discourages Indian entrepreneurs from growing, and as a consequence there are few large productive firms and too many small unproductive firms.   

But the constraints on large firms appeared to have diminished since the early 2000s, despite the fact that there has been no change in the IDA. The reforms that started in 1991 mostly dismantled the reservations for small-scale industries and the industrial licensing laws. They left the IDA untouched. Consider the evidence in Figures 1 and 2. Figure 1 shows that the thickness of the right tail of formal Indian manufacturing increased between 2000 and 2015. Figure 2 shows that average value-added per worker is increasing in firm employment in 2000 and 2015. This relationship is more attenuated in 2015 compared with 2000, particularly for firms with more than 100 workers. If the marginal product is proportional to the average product of labour, and profit-maximising firms equate the marginal product of labour to the cost of labour, then this suggests that the effective cost of labour has diminished for larger Indian firms compared with smaller firms.

Right panel shows coefficients and 95% confidence intervals from non-parametric regressions of log VA/Worker on log employment using Epanochnikov kernel with a bandwidth of 0.6.  Employment is the number of non-managerial workers.  Log VA/Worker is residualized by industry and year fixed effects.

The decline in the bite of the IDA does not come from a de jure change in Indian labour laws, but rather from a workaround from the rapid development of the labour contracting industry in India since the early 2000s. The IDA only applies to a firm's full-time employees. Workers supplied through third-party intermediaries are not the firm's employees for the purposes of the law. Contract workers are considered employees of the staffing companies, and the staffing companies themselves have to abide by the IDA. This loophole provides customer firms with the flexibility to return the contract workers to the staffing company without being in violation of the IDA. Figure 3 shows the probability that contract workers account for more than 50% of total firm employment as a function of total firm employment. Among smaller firms, there has been no discernible increase in the share of firms where contract labour is at least 50% of the workforce. In contrast, there has been a dramatic increase among larger firms, particularly those with more than a 100 workers. We trace this increase to a 2001 Indian Supreme Court decision that made large firms less reticent to rely on a large pool of contract workers for ‘core’ activities.

The relaxation of labour constraints facing large Indian firms since the early 2000s came from exploiting a loophole, rather than a de jure change in Indian labour laws. In this sense, this episode is another example of what many people in India call ‘jugaad’, which means (roughly) ‘finding informal solutions to problems’. But as with all informal solutions, it potentially raises other costs that may make further progress difficult. In particular, one may be concerned about further growth potential when the most productive firms rely on contract labour for such a large share of their workforce. Future work should also consider the implications of this development for labour training, skill upgrading, and bargaining power.
