Cornell Economist Robert Frank Makes an Interesting Point:
“The rich have been spending more simply because they have so much extra money. Their spending shifts the frame of reference that shapes the demands of those just below them, who travel in overlapping social circles. So this second group, too, spends more, which shifts the frame of reference for the group just below it, and so on, all the way down the income ladder. These cascades have made it substantially more expensive for middle-class families to achieve basic financial goals”.
Why do Economists Argue?
David Segal’s article is quite good. Here is a key insight from his piece:
“This is not to suggest that economics is a total free-for-all, lacking a broad consensus on any subject. Polls of economists have found near unanimity on topics like tariffs and import quotas (bad), centralized economies (very bad) and flexible, floating exchange rates (very good). Nor is it fair to say that economists have done little to help in the latest crisis. A depression seemed possible two years ago, and thanks to the ideas of economists, that didn’t happen.
But economics will forever have to contend with the biggest X factor of all: people. As Mr. Solow notes, you feed people poison, and they die. But feed them a subsidy and there is no telling what will happen. Some will use it wisely, others perversely and some a mix of both”.
