How do economists define the thresholds that signal an overheating economy?
Core argument: Mankiw identifies core inflation above 3% over a 12-month period — a threshold not crossed in the past 25 years — as a signal of potential economic overheating.
Concerns about economic overheating are highlighted by Mankiw and Furman, who emphasize the risks of rising inflation and interest rates. Mankiw warns that core inflation exceeding 3% over a 12-month period, a threshold not crossed in the past 25 years, signals potential overheating. Furman adds that a 10-year nominal interest rate surpassing 3% could necessitate fiscal policy adjustments. Both economists suggest that such conditions could lead to macroeconomic instability, with potential negative impacts on GDP and unemployment rates. Despite these concerns, current TIPS [Treasury Inflation-Protected Securities] data indicate moderate inflation expectations, with the five-year rate at 2.5% and the 10-year at 2.3%, suggesting limited anticipation of sustained high inflation.








Ed Comment:I love this PIAAC data. And I want Ben and you to explore it and the studies of others who have, especially the relationship between, test scores, wages, and race, i.e., how much more or less do blacks earn relative to whites for a given test score. But this seems like a not-so-interesting use of the data (even though I'm eager to see any use of the data). No surprise 1) talent has moved to the large cities, especially on the coast 2) the Scandinavians in Minnesota are higher scoring on average (and in Europe too). And 3) there are a few smart doctors, lawyers and successful businessman scattered around rural America.PS and no surprise, the effect of education wears off by the 12th grade. It seems that teaching (dumb) young kids accelerated skills is akin to teaching dogs parlor tricks. It doesn't make them smarter. It just stresses them out. In the end, they end up where they are going to end up. That's not to say that teaching people technical knowledge/skill, especially smart people, doesn't make them more productive. It's just that's not what the overwhelming majority of education does. It teaches generalized skills to the vast majority of students who aren't very motivated to learn more than a modicum of those skills and have little use for them as adults (because they aren't reliable enough users of those skills for anyone to rely on them to use them). As bill gates, the person who has spent hundreds of millions of his own money, his own way, with the foremost experts advising him, trying to prove the no-improvement history of education wrong and failing spectacularly (but bravo for trying): "It's easier to cure malaria than it is to raise test scores." And: "The problem isn't unmotivated teachers: it's unmotivated students."
