Worth reading in full.  Not new insight, but very nicely written.

In order to change the behaviour of the poor, one must first understand it. It is this understanding that behavioural economics promises to codify into knowledge. To be sure, the WDR readily acknowledges that even the rich, the economists, and the World Bank staff themselves, might be subject to cognitive biases.

But nowhere in its 230-odd pages does the report present an instance, or even a hypothetical example, of a behavioural economics-inspired policy intervention whose target is, say, a class of billionaire investors, despite the fact that today, compared to the poor, this is a group that wields far more influence, per capita, on a nation’s economic destiny. Changing their behaviour — for instance, manipulating them into deploying their billions on productive rather than speculative investments — could generate more beneficial, and more effective, outcomes than micro-manipulating the financial decisions of a poor peasant.
