Defining productivity is one of the hardest things on economics. A well-known economist-journalist reminded me of it when I used that word in an email and he asked me for my definition. It is hard. It is a bit like beauty and obscenity. You know it when you see it. Of course, it is not as hard as those concepts. In factories, labour productivity can be measured. But, capital productivity is somewhat more problematic and low productivity may not be entirely for internal reasons.
Suppose the construction of a factory begins in year 1 and some capital is committed. But, let us say, approvals take forever to come – environmental, legal, utility connections, etc. Here, capital has been committed and invested but yet, there is no production to show. There is unproductive capital here. But, one cannot say that it is the fault of the enterprise or the entrepreneur.
Total Factor Productivity (TFP) is even more complex. It is the residual. Output growth that cannot be explained by input growth is TFP.
Further, in the case of India, with services dominating the economy, it is even harder to get a grip on productivity. Measuring productivity in service sector could be problematic as there could be a conflict between the micro and macro on this. This is not the place to elaborate it but more on that on another occasion.
It took a laborious (for me) blog post to establish that units/factories covered by the Annual Survey of Industries are not ‘informal’. They are registered under the Factories Act, 1948 under Sections 2 (m) (i) and 2 (m) (ii). They are not covered in other surveys of unincorporated and unorganised enterprises by the NSSO, etc.
Therefore, productivity of the smaller factories – to be presented below – is not the same as productivity of informal manufacturing enterprises.
I prepared two Tables on productivity statistics for Annual Survey of Industries (ASI) – Factories. The latest ASI is for 2014-15 released in March 2017. The tables below are based on statistics presented in Statement 11-A (‘Principal Characteristics by the Size of Employment’ – Section 7, page no. S7-3).
The Tables are along expected lines.
(1) Capital productivity of smaller units is better because they deploy lesser capital. In a relatively capital scarce country, that is better. But, is it true that India is still as capital starved as it used to be, with capital flows being global and Indian savings rate being upwards of 30%? In fact, how much of the capital scarcity is because Governments capture a large portion of the national savings through the banking system?
(2) Labour productivity of larger units is much better because they employ fewer workers relative to the output or GVA they generate.
(3) What is interesting is that on capital productivity measures, smaller units are not decisively better off. GVA/Invested Capital Ratio is the same for both small and big factories. Productivity of working capital is far better for larger factories. Of course, that tells us how big a constraint working capital is, for smaller enterprises. That will be my third post.
(4) Output/Wage Ratio (in Rupees) is better for smaller units. May be, because they do not pay well? But, GVA/Wage ratio is much better for larger factories.
(5) Similar is the story with respect to Emoluments.
(6) Overall output/input ratio is better for larger enterprises.
These two tables should help us design appropriate policy intervention. Some conclusions that emerge, in my view:
(1) India needs both large and small factories. In fact, small factories arise for the most part as part of the supply chain for larger factories.
(2) Working Capital Efficiency for smaller factories can and should be improved. The onus is on the Reserve Bank of India and on larger corporate customers
(3) Smaller units need labour skills and training
(4) Larger units need to improve their capital and labour productivity but not to beat their smaller counterparts in India but to compete globally. They must benchmark themselves globally.
(5) Clearly, the data do not make the case for the country to ignore the need to allow enterprises to grow big. There is no case for a ‘anti-big’ bias. In fact, if anything, ‘informal’/’unorganised’/’unincorporated’ enterprises may have even poorer productivity statistics than the small factories covered by the ASI.
