For Duflo and Banerjee, an important part of their work has been ensuring that the agency of the "beneficiaries" -- usually, in developing countries like India, poorer individuals -- is put at the centre of any policy design. This is a crucial way in which experimental results are often better than large scale data-based inference, says Mihir S Sharma.

Mihir S Sharma gives us a rundown of what could happen, depending on the number.

'The oddest thing about this general election campaign so far is that one might think that the BJP was fighting with its back to the wall, rather than as the favourite to win.' 'Perhaps there is something they know that we don't,' says Mihir S Sharma.

The expectation that Mr Modi would be a major reformer, capable of reinvigorating the Indian economy, were based on a complete misreading of both his actions and his performance as Gujarat chief minister, says Mihir S Sharma.

'Fighting terrorists is one thing. Fighting insurgents is worse. Fighting a population is worst of all,' says Mihir S Sharma.

'Anyone on Indian Twitter, Facebook, or any of the other forms of social media that matter (except elite forums like Instagram) understands instantly that it is dominated by upper-caste North Indian men.' 'Other voices are silenced and attacked,' says Mihir S Sharma.

'I would have expected that, once firmly ensconced in the director's chair by 2:15 am, the not-director of the CBI would have called for pen and paper and hand-written a few clean chits.' 'Clean chits over Rafale; clean chits to the PM's secretary in the coal bribery case; a clean chit to Hasmukh Adhia on whatever claim Subramanian Swamy has cooked up about him...' says Mihir Sharma.

'India may well be a religious country, but that is precisely why we need to avoid criminalising blasphemy,' argues Mihir S Sharma.

'As long as the government owns the banks, bankers will follow signals from politicians as to how to lend.' 'State-owned banks will remain State-owned banks as long as the current dispensation is in power -- and certainly there will be no change if the other chaps get in,' says Mihir S Sharma.

'Ask a beat journalist their opinion, and you will always be told that they are more worried about writing something that would upset a company than something that would anger a politician,' says Mihir S Sharma.

The flawed response to the crisis has fed a us-vs-them mentality in which the banker, the expert, the coastal entrepreneur, the immigrant, the foreigner are all villains. The crisis was not that much of a problem; the response -- the over-reaction, the sovereign debt build-up and the lasting anger -- is the problem, says Mihir S Sharma.

'The entire swathe of Internet trolls -- who now apparently serve as the ideological brains-trust of the BJP -- would have looked at each other in puzzlement, thinking: What kind of warning is that?' says Mihir S Sharma.

'This is the era of images; no speech that Mukherjee could have given could counter the sight of a senior Congressman, elevated by the party to Rashtrapati Bhavan, standing rigidly next to the RSS gerontocracy as those worthies delivered the organisation's faux-fascist salute,' says Mihir Sharma.

'This is obvious to everyone except those in denial; it is a national shame.' 'To that extent, blaming any particular government is an insufficient response,' argues Mihir S Sharma.

While GST and insolvency laws are among the major achievements of the Modi government, the list of failures include demonetisation, toxic banks, manufacturing hiccups and most prominently bizarre job creation figures. Mihir S Sharma takes a look at the four years of Modi government.

'Bureaucrats have transformed a project meant to empower the poorest Indians into one that empowers only babus and disempowers everyone else,' says Mihir S Sharma.

'The link between global warming and weird, extreme weather events is being better understood every year.' 'India is particularly at risk from such events.' 'Indian communities and urban centres don't have the resilience needed to survive such disasters,' says Mihir S Sharma.

'The current BJP leadership believes the party's expansion across India, and thus their own survival at the top, depends on injecting communal tension into areas where it has so far been largely controlled,' argues Mihir S Sharma.

The failure to reform has meant that there is no buzz about job opportunities, or about urban opportunities enticing young people off the farms. And it is this failure that has contributed to the widespread disappointment that threatens to make the next general elections closer than expected, says Mihir S Sharma.

'Anything other than a complete, 2014-style victory will be far more devastating for him then it would be for anyone else.' 'Disciplining restive party members, and taming recalcitrant allies will then be far more difficult for him,' says Mihir S Sharma.
