He also asks for the first non-hyphenated use. The first JSTOR entry without a hyphen for "macroeconomics" is Lawrence R. Klein, "Macroeconomics and the Theory of Rational Behavior," /Econometrica /14(2), April 1946, pp. 93-108. The oldest JSTOR entry for "macroeconomic" without a hyphen is Harold L. Reed's Review of Arthur W. Marget's /The Theory of Prices/ in /American Economic Review /32(3, part 1), September 1942, pp. 561-564. For "microeconomics" sans hyphen, JSTOR's oldest is Martin Bronfenbrenner, "The Role of Money in Equilibrium Capital Theory," /Econometrica/ 11(1), January 1943, pp. 35-60. ** <http://www.jstor.org/view/00129682/di952476/95p0084j/0?currentResult=00129682%2bdi952476%2b95p0084j%2b23%2c00000003&searchUrl=http%3A%2F%2Fwww.jstor.org%2Fsearch%2FAdvancedResults%3Fhp%3D25%26so%3DOldestFirst%26si%3D1%26q0%3Dmicroeconomics%26f0%3D%26c0%3DNOT%26q1%3Dmicro-economics%26f1%3D%26c1%3DAND%26wc%3Don%26sd%3D%26ed%3D%26la%3D%26dc%3DEconomics> Reed again the same 1942 review is also the oldest use of "microeconomic" without a hyphen in JSTOR. I am not sure, however, why we should give much significance to the presence or not of the hyphen. Both versions are still in use and, I suspect, don't reflect anything very significant historically.
