For a few decades, economists used to imagine how the world works, write down a theory describing their idea, and call it a day. If some statisticians came along and found some support for the theory, well, great! But usually they didn’t, and that was fine too. As one old joke put it, if an idea worked in practice, economists would ask whether it worked in theory.
One of the less heralded truths of economics is that growth miracles, while they make for good press, are overrated. It’s an insight that could help us better understand the outlook for developing countries such as China.
How many times have you heard someone say that the Federal Reserve’s asset-purchase program known as quantitative easing was ineffective? At least, that’s what I keep hearing from the usual pundits arguing their case.
The harm of inflation cited in economics textbooks seems laughably unimportant. For example, inflation generates so-called shoe-leather costs — a term for the hassle of moving money from one’s brokerage or savings account to one’s checking account. This hassle is larger when prices change a lot, since you have to put spending cash in your wallet more often.
Now and then a worthy economic proposal comes along that seems as politically unattainable as it is sensible. Then, on closer inspection, you see that it’s more than a policy-wonk’s fantasy. And you wonder whether it could actually prevail.
