We have seen how the state planning for alleviating famine and food shortage fails miserably in a planned economy. Often in a mixed economy, government seeks proper control over the agriculture and food sector and that becomes the reason of corruption and further suffering at the times of need, scarcity and famine.^[1]
On the other hand, in a free market, the profit motive acts efficiently to assuage worst kind of shortage and famines and hence actually save the populace from extreme starvation.
In a free market, there is a tendency of price of wheat, rice or crude oil (or any other commodity that can be stored), to be equal to its expected prices say after 6 months or a year, that is, free market naturally depresses the unexpected price rise.
Whenever government intervenes with the market, the market moves away from this natural tendency and the consumers suffer unexpected shortage and famine.
The force behind the tendency of uniformity of present and expected future prices of a commodity in a market is the profit motive of free enterprisers. Any disturbance in prices provides a chance for higher profit rates and as the enterprises exploit it, the discrepancy in the prices reduces to minimal.

Solving the Shortage of Grains

To understand this, let us take the case of an unexpected flood or drought in an Indian region (say Bihar, or Andhra Pradesh). Because of drought, the production of wheat will be reduced (let us say it reduces by 1/12th of the average wheat production in an year). Obviously, because of the shortage in production, the price of wheat is expected to rise after say, 6 months. The enterprisers looking for making higher profits will speculate this expected price rise and will start storing the wheat at the current lower prices to save it to make higher profits in future by selling the stored wheat at higher prices.
Their speculative storing of wheat will result in a raise of current price of wheat, as there will be lesser wheat available to be sold to consumers, and the enlarged quantity of wheat for future will reduce the future prices of the wheat.
Because of current higher prices, the consumers will also start accommodating themselves to the shortage of wheat by reducing the consumption of wheat and checking the wastage. This thriftiness on behalf of consumers will allow them to sustain the time of absolute scarcity of wheat and that will further reduce the expected future price of wheat. Thus, at one hand, speculators will increase the current prices of wheat by storing it for future sales at higher prices, on the other hand, the increased available quantity of wheat for future and the thriftiness of consumers at present will reduce the expected prices of wheat in future. As a result, the maximum possible increase in price of wheat at the period of most scarcity will also be not very much more than the current price of wheat plus the storing and preserving charges of the wheat by speculators.
In absence of speculators, as most of governments illegalizes speculation for price control, the consumers will never realize the actual shortage of wheat because there will be no sign of scarcity by means of price rise and will continue consuming wheat as normal. On the other hand, although the stored wheat will satisfy the demand of consumers for first 11 months, there will be no wheat left for the next 12th month of year as the total wheat produced is already less by 1/12th of the average required for an year. Such a situation will not only make people suffer starvation but will also fail to reduce wastage when it could have been. In addition, it will provide further chances of bureaucratic governmental corruption.
The profit motive will also alleviate the situation of famine and scarcity by means of another natural force of free market that tends to equalize the price of a commodity at all places. At a time when Andhra Pradesh or Bihar is suffering famine and food shortage, the dealers at other parts (say Uttar Pradesh, Punjab or Tamil Nadu) will seek higher profit rates by selling their stored wheat to the consumers in Bihar or Andhra Pradesh. This will result in a slight increase in price of wheat at the local markets while the increase quantity of wheat available for Bihar or Andhra Pradesh consumers will reduce the unexpected rise in price of wheat at markets there. Thus, the shortage of wheat at a region will be spread to whole India and hence will reduce its effect to minimal, all will share the increase in price of wheat, and that will reduce any extra burden on the consumers of famine suffering area to negligible.
The speculators cannot store the wheat for more than a period of 12 months as by that time, the new crop of wheat will arrive in the market and that will reduce the price of wheat to normal.

Issue of Oil Shortage because of Corrupt Oil Barons

The same principles of free market will also tackle any unwanted situation in the market of crude oil and petroleum or any storable commodity.
In the previous post, while discussing the Market Anarchy^[2] , one of my friends raised the issue of Oil Barons, asking what will happen to free market if the Arab Oil Barons tries to control the market because of their influence on oil production.
Let us assume that all Oil Barons of Arab makes a union and tries to control the free market by imposing an artificial scarcity of crude oil (although this is impossible because reducing supply of oil will reduce all income of those oil barons as they have no other means of profitable production).
The speculators of free market will certainly foresee the future shortage of oil and will maintain their oil storage to make higher profits. That will obviously increase the current prices of available oil and hence will introduce the thriftiness in consumers, making them more able to sustain the period of oil shortage. Consequently, it will reduce the chances of unexpected increase in price of oil at extreme periods too.
On the other hand, Indian free market will also tend to increase its oil production to make higher profits. In addition, profit motive will tend the oil producers of other nations (like USA or Russia etc) to sell their oil to the Indian market. That will obviously tend to spread the scarcity of oil through out the world and hence will assuage the problems of Indian market. Hence, although the economy of India and actually whole world, will suffer a comparable loss but that would not be of any considerable degrees. On the other hand, Oil Barons depend only on oil production, their loss at not selling the oil will be huge and directly pointed towards them, and that will break their union.
Conclusion: A free market inadvertently safeguards itself against any sort of scarcity of any commodity by means of the profit motivated market forces. As speculators guard the market and hence the well-being of consumers as true and honest soldiers (as their vested profits and interests are strictly attached with the consumers), the free market necessarily remains free of any discrepancy in the prices of any commodity.
Even the administrators of mixed economy have realizes the power of forces of free market that is why Indian government issued allowance of speculations over wheat few months ago^[3]. Certainly, it is a positive step towards the Free Market.
