Where are the bottlenecks to growth in India right now?

So this is the question on my mind - given the situation that India is in right now, where should we be investing the limited funds available to us? The situation being that government budget is constrained by the fact that the fiscal deficit should not be more than 5% of GDP. With the Goods and Services Tax coming up next year, there will be revenue sharing between center and states and the budget of the Central Government will be constrained even further. At present the government is finding it hard to implement the recommendations of the 7th pay commission. The manufacturing sector is lagging as government is not undertaking major projects (such as new dams, nuclear reactors, smart grids, etc.) at this stage and this is showing in corporate earnings of the industrial companies. The economy is in a dismal state right now.

The Goods and Services tax is expected to be a friendlier tax regime than the present VAT which suffers from 2 important drawbacks: 1. Cascading taxation and 2. Inability to tax imports on par with the domestic production. With the states sharing the revenue from the single GST tax regime, the Center will have to delegate increasing responsibilities to states than done previously. This would also open up the opportunities for state level debt and state government bonds similar to the central government bonds. A constitutional amendment will be required to enable the states to collect the GST.

The Congress had brought the GST bill in Parliament in UPA2 regime but were not able to bring the states on consensus on a common tax rate and so the bill was stalled. Now the BJP has been able to bring the states to consensus on the GST tax rate and the Congress is blocking the GST bill in Rajya Sabha.

The second factor that can boost the economy is Foreign Direct Investment in critical sectors such as power (nuclear reactors, smart grids, etc.) and transportation (high speed rail). These are very attractive sectors commercially and corporations in Japan and USA provide debt financing at low interest rates for such environmentally friendly projects. For example, Japan has offered to finance the the first bullet train in India, having a cost of $15 billion, at a 1% interest rate.  There are a lot of opportunities in the nuclear power sector after the India and USA reached a joint agreement on development of civilian nuclear power (Link to September 2015 story).  GE-Hitachi had started discussions on building nuclear power plants in India (Link to February 2015 story).  These deals are stalled right now.

Generating more nuclear power will help reduce our dependence on coal imports for generation of electricity. This could potentially solve the persistent power deficit problem in this country and make power production immune to supply side shocks from high price of coal and natural gas when the Rupee depreciates.

The FDI regime in India can be changed from limited FDI (49-50% in most sectors) to 100% FDI with a caveat that the business has to support local jobs. This has been implemented in multi brand retail where we have seen Walmart set up stores in India and source large amounts of their merchandise locally. USA has similar FDI norms where car manufacturers have to manufacture at least half of their cars in USA. I believe this would make the FDI route more attractive for businesses and multi national corporations.

I think these factors can significantly improve the growth prospects of the Indian economy at this point of time.
