An article published at Macroscan on the dilemma of the Indian government about whether to deregulate the price of oil or not, the author argues for not to do so. However, I think he needs more than the analysis he is basing his argument on. The simulation is based on Tinbergen style simultaneous equations model of the Indian economy. So my 5 cents to the debate are as follows:
There are several general equilibrium effects of an oil price shock that have to considered. How are people going to react to the change in price of oil? In the first place, shielding the consumers from oil price shocks has distorted consumer decisions. Combined with shoddy public transportation system, it has lead to a higher demand for private transportation vehicles. If government passes on the oil price changes to the consumer, the consumers might respond to the relative price changes. Over the period of time there will be further demand for efficient public transportation and the reliance on oil for private transportation might actually go down leaving the net effect on GDP close to zero. Also, reduction the oil subsidy will reduce the over fiscal deficit and lower the inflation tax. The government might decide to channel that expenditure somewhere else like better schools or highways! But to account for such kind of changes you will have to simulate a micro-founded general equilibrium model and not a Tinbergen style simultaneous equations one (NIPFP working paper No. 2012-99) which does not allow for equilibrium responses from economic agents (the famous Lucas critique!). I think right assessment of what should be the appropriate policy in the case of oil price deregulation cannot be made till such analysis is undertaken. You still might have a case for not deregulating the price of oil but it would be based on a more robust analysis.
