The poor should be less prone to show this effect
:
Data collected with Anuj Shah in 2012 support this prediction. We presented participants with versions of the tax-rebate versus the stock value scenarios. The well off showed a different proneness to spend under the two frames, whereas the poor did not; p < .05 (N = 141).

110
loans are particularly attractive
:
The other common reason cited for excessive borrowing is myopia of some form. What is interesting in this narrative is that myopia here—tunneling—is not a generalized personal trait. Everyone tunnels when faced with scarcity. And recall that the same force that generates tunneling also generates the focus dividend. Unlike myopia, tunneling has positive consequences as well.

scarcity makes this problem a whole lot worse
:
There are many studies of the planning fallacy. Good reviews are: Roger Buehler, Dale Griffin, and Michael Ross, “Inside the Planning Fallacy: The Causes and Consequences of Optimistic Time Predictions,” in
Heuristics and Biases: The Psychology of Intuitive Judgment
, ed. Thomas Gilovich, Dale Griffin, and Daniel Kahneman (Cambridge: Cambridge University Press, 2002), 250–70; D. Lovallo and D. Kahneman, “Delusions of Success,”
Harvard Business Review
(2003): 1–8. While there is no explicit study of the impact of scarcity, it follows naturally that the planning fallacy would prove more pronounced among those who are especially tunneling, as occurs under scarcity.

6. THE SCARCITY TRAP

123
Everywhere is walking distance
:
Quote from Steven Wright. In W. Way,
Oxymorons and Other Contradictions
(Bloomington, Ind.: AuthorHouse, 2005).

123
A typical vendor buys about 1,000 rupees
:
These data draw from Dean Karlan and Sendhil Mullainathan, “Debt Traps” (working paper, 2012).

123
a little over $2
:
In this book when we report dollar equivalents, we simply convert using prevailing exchange rates. Yet many experts feel this can paint a misleading impression because people in different countries also face different prices. So the vendor, for example, will also have lower prices for food and other items. As a result, her income in nominal dollar terms does not adequately
reflect her purchasing power. Economists have suggested using purchasing power parity instead of nominal exchange rates. In the case of India, this would result in an income that is roughly 2.5 times higher for the vendor.

126
An initial scarcity is compounded by behaviors that magnify it
:
Economists and especially development economists have focused on what they call
poverty traps
—the notion that those who begin poor will stay poor. A commonly discussed mechanism is a lucrative investment opportunity that requires a fixed amount of capital. The rich have enough capital to make the investment while the poor will find it hard to save up enough money to do so. Other mechanisms discussed include aspirations and myopia. Relevant references can be found in Debraj Ray, “Development Economics,”
The New Palgrave Dictionary of Economics,
ed. Lawrence Blume and Steven Durlauf (2007).
