For one, he was critical of experts blowing hot and cold when it comes to monetary policy decisions.
"On the domestic side, there is a clear relationship between expert analysis and official decisions. Before policy decisions, the expert analysis is often illuminating. But once the decisions are taken, it is truly striking how the tune and tone of the analysis change. Analysts fall over backwards to rationalise the official decision," he said while delivering the VKRV Memorial Lecture here.
Some, according to Subramanian, called on the government to stick to the pre-announced target while others wanted it to go slow on consolidation. Some even asked for expanding the deficit, especially this year, given the weakness of the economy after demonetisation.
He pointed to the inconsistency in opinion of experts, which is is evident from various examples of past few months.

Citing the example of RBI monetary policy review during demonetisation, Subramanian said a consensus had built up among the investor community and economic analysts that the RBI would lower interest rates.
It turned out that the monetary policy committee (MPC) did not cut rate, he said, adding that it rather signalled a more hawkish stance -- by going from accommodative to neutral -- and has maintained that stance since then.
"Yet, instead of criticising the official decisions, as consistency would demand, analysts found ex-post logic to attribute merit to these decisions. That is, far from criticising the central bank for holding rates constant over the past three announcements, analysts praised the policy stance as prudent and helpful in boosting the credibility of the inflation-targeting framework," he said.
"My claim is that experts often hold back their objective assessment. Instead, they censor themselves, and in public fora are insufficiently critical and independent of officialdom, whether the officials are in Mumbai or Delhi. To the extent they offer criticism, it is watered down to the point of being unidentifiable as criticism," he added.
He wondered as to why experts refuse to speak the truth to power.
Throwing more light on the peculiarity, Subramanian said that before policy decisions are made, observers tend to express their views that they think officials are likely to take on board. After policy actions, they try hard to endorse the decisions already taken.
"As a result, we in the government do not really benefit from their wisdom. This is a serious problem, because high- quality policymaking demands high quality inputs and high quality debates," he stressed.
Speaking about bankers' dilemma, Subramanian said they are careful not to get on the wrong side of the government or the RBI, because they worry about losing access and because they are regulated by them.
Quoting the famous writer Upton Sinclair, he said, "It is difficult to get a man to understand something when his salary depends upon his not understanding it."
"Against this background, most reasonable economists would say the economy needs all the macroeconomic policy support it can get: instead, both fiscal policy and monetary policy remain tight. And on top of that, there are some officials who even think that policy should get tighter," he said further.
The CEA also referred to a famous joke about asking three economists for a view and getting four different answers.
On the behaviour of officialdom, he said all they want is validation for their actions.
"So, in the short run, it will want to shape opinion in its favour. But in the long run, that is perhaps not desirable. Public interest is perhaps better served by richer debate that encompasses critical views, including of officialdom. Officials should signal that clearly," he suggested.
