Inflation is directly related to increases in income. If changes in income are taxed, or weaned away in the form of loans to the government, inflation can be taken care of.
The Reserve Bank of India is so obsessed with inflation that it has kept money tight for a long, long time. It does not seem to be bothered that its efforts have not been successful. It could argue, and so it will, that if it had not kept money as tight as it has, inflation would have been worse. That is like the socialist argument that the economy would have been worse but for socialism.
Actually, as The Hindu (November 15) has remarked, the policy has inflicted on the Indian economy a triple whammy — the weak monthly industrial data for September, still high retail inflation for October and the latest poor external trade figures. Though inflation has indeed come “down” to 7.47 per cent that still is a very high figure.
Regulating inflation is basically a control problem. Therefore, it is rather surprising that economists have not looked into the way engineers operate control systems.
If the RBI Governor D. Subbarao had studied engineering and not physics in the IITs, he would have known that engineers often use a three-term control system — the first to control the function, the second to control the integral of the function and the third to control the differential of the function. In economics, that would have been taxing incomes, wealth and change in incomes.
For some reason or other, economists are interested only in taxing incomes and wealth and not changes in income. That is a pity because inflation is directly related to increases in (money) incomes. Theoretically, if changes in incomes are taxed, inflation should tend to become zero.
Unfortunately, economists have important reasons to make exceptions and give concessions. Hence, taxing increases in incomes only partially may not reduce inflation to zero, but yet will be preferable to tight money.
Three taxes
Therefore, I suggest three kinds of taxes: income tax, wealth tax and taxes on increases in annual income. Ideally, wealth tax is supposed to reduce wealth to zero.
It has done that largely in the case of British nobility. In a dynamic economy, wealth has always been generated (and lost).
Often, wealthy people find ingenious ways of not paying taxes. Hence, though ardent socialists disagree, we may even drop wealth taxes and replace them by taxes on changes, rather increases only, in incomes.
It is well known that increases in incomes tend to cause inflation for short terms only — unless the increases take place continually.
Unfortunately, that happens often — inflation increases demand for higher income and that increase in incomes pushes up inflation further. Actually, it all depends on how the increased income is used. If it is used to buy things that are readily available, little or no inflation will result. On the other hand, if the increase in income is spent on articles in short supply, that will definitely cause inflation.
Therefore, if every person whose income has increased does not spend it but holds it till the good he wants is readily available, there will be no inflation. He may do better and give the amount as an advance to the producer to increase production.
Unfortunately, such restraint is rare; it is also virtually impossible to enforce, because nobody knows which goods’ output should be increased to raise the production of any product.
Certainly, a mere increase in producing the item demanded will not do; we may have to increase the production of electricity, raw materials, roads, education and healthcare. Sorry! We cannot ask everybody whose income has increased to pay for the increase in production of all the required items needed to increase production of the particular item desired.
Gold-backed bond
Let us make it simpler. Let the Government treat the tax as a sort of short-term loan. How short or long that term should be can arouse much debate. It could be one year or even 10 years. Possibly, three years is the maximum that people will tolerate. Then, the increase in income is not exactly taxed outright, but returned sometime later. Unfortunately, even the amount to be returned will cause much debate or even distress — particularly in an inflationary economy.
We could ameliorate that distress somewhat by indexing the loan, say, to the price of gold. Then, the system may operate as follows. One, a temporary deduction is imposed on taxpayers on the increase in annual incomes.
The taxpayer may deposit the amount deducted in a bank in a gold-price-indexed bond. (No gold is purchased, and hence, the transaction should not affect the price of gold.) The taxpayer may be given a further sweetener of a small interest of around 2 per cent or so. The bank credits the total amount of principal plus interest to the taxpayer’s account at the end of the due term.
In effect, the Government gets a low interest loan for a short term. Where could the Government invest this? Usually, the Union Government will collect the tax and spend it the way it likes.
That gives a bonanza to ministers, and they would not like to surrender it. Let us hope, against hope, that we will get a selfless minister, and he will let the amount to be competed for by a State or a district or a tehsil or even by a panchayat.
Then, the lower government agency offers inflation-indexed loans for a short term on various projects; the taxpayer gets a choice about whom to patronise.
Let us remember that everyone grumbles about paying taxes, but gladly contributes happily to an institution of their choice.

brilliant write-up. But what i don't get is that why should tax on "changes in income" be treated as a loan offered to the govt. instead of being tolled as a direct tax? what is the main benefit of using it as a low-interest loan rather than a direct tax imposed. probably the latter shall help in stagnating the economy further strongly. If it's only due to the reason that such a sudden action as the latter might be seen as a measure of looting people further, it's understandable. besides that, I don't see a reason for the same.
Analogy to PID controllers appears to be apt, but sir, there is a problem with pedantic engineering. 'Inflation tends to increase the income' you say. Where does it happen sir? Ask any non-IT engineer toiling in a textile mill. Even if income is related to inflation, it is only in narrow area of Govt employees and even if it happens, the lag time is so large, the relation becomes insignificant.
Again, indexing against the Gold price is misleading. As you very well know, the gold price is not an absolute. It is affected by currency rates and of course, inflation! Isn't it?
Moreover, the PID controller tends to make the error zero by controlling some other degree of freedom of the system. That too to operate it within the boundaries or contraints. Whereas, economy can not always be constrained. It should be allowed to expand. Income and wealth should be allowed to expand in real terms, not to be contrained.
Preposterous idea.. No logic at all.
The Prime Minister at one of his recent addresses at Bombay IIT,
exhorted engineering students to enter into politics. India needs
professional engineers and physicists to join politics. Engineers who
have gained problem-solving experience in their profession would be
ideal to solve the many faceted, myriad problems. A physicist who has
actually come up with new solutions to engineering problems would also
be ideal to solve the problems of India. India is uniquely burdened
with so many problems that are not faced by many societies in the
world. Indians have not reformed themselves, have not reformed their
society, so you see medieval thinking and dark age superstitions
existing side by side in the society and even within the same
individual. This is unique to India. Minds that have tackled calculus
and quantum physics are well suited to solve the problems of
inflation, the caste system and untouchability, open defecation,
ecological disasters etc. many of which are unique to India.
Very creative to bring the concepts of PID controllers to the area of taxation. The PID
controls are based on an overall assessment of the past (integral),
present(proportional) and the future(differential). However, there are some serious
issues in implementing this idea for taxation as had been very ably commented upon
by Ankur and Nn. The RBI Governor may possibly have turned out better if he had
studied engineering rather than physics at IIT, as the columnist suggests. However,
Indiresan surely would have done better if he had studied at any IIT rather than
teaching there.
