Economic Laws Explained Simply
Diminishing returns means more input yields less output over time. Supply and demand set prices.
What was corrected
Article cited the real Gneezy & Rustichini (2000, Journal of Legal Studies) Israeli daycare late-fee study but stated late arrivals 'increased by 70%,' when the study's actual finding is that late arrivals roughly doubled. Separately, the article correctly cited Autor, Dorn & Hanson's 2013 American Economic Review paper on the China trade shock (1990-2007) but attributed to it a 'approximately 2 million US manufacturing jobs' figure that actually comes from a later follow-up paper by the same authors covering 1999-2011 and a broader job-loss measure (not manufacturing-only, 1990-2007).
Gneezy & Rustichini figure corrected to 'roughly doubled.' Autor/Dorn/Hanson passage corrected to state the 2013 paper's actual finding (import competition explains roughly a quarter of the contemporaneous US manufacturing employment decline) and separately, correctly attributed, notes the ~2 million figure to the later 1999-2011 follow-up study.
Why this is better
Independent verification found 4 of 6 major citations in this article (Kerr 1975, Benabou & Tirole 2003, Helpman & Krugman new trade theory, Porter 1985) were accurately described with correct figures - this article was substantially cleaner than others flagged in the same scan, with only two specific numbers needing correction rather than unverified sources.
