Deirdre McCloskey

American economic historian, economist, and rhetorician (b. 1942), Distinguished Professor Emerita of Economics, History, English, and Communication at the University of Illinois at Chicago. Trained at Harvard (BA, PhD); long career at the University of Iowa before UIC. One of the most distinctive voices in late-20th- and early-21st-century economic history: at once a serious cliometrician (her early work on British iron and steel was core to the cliometric revolution), a methodological provocateur (The Rhetoric of Economics, 1985, helped open the methodology-of-economics field), and the author of the most committed ideational/cultural account of modern economic growth.

Intellectual program

McCloskey’s late-career argument, developed across the Bourgeois Trilogy (Bourgeois Virtues 2006; Bourgeois Dignity 2010; Bourgeois Equality 2016), is that the most important fact about the modern world is the roughly 30× rise in real per-capita consumption — what she calls the Great Enrichment, preferring this to “Industrial Revolution” — and that this change is too large to be explained by any of the materialist factors economic history typically deploys. Capital accumulation, slave-trade profits, coal, savings rates, factor prices, ghost acres, and even institutions are each individually too small, on her quantitative reading, to deliver a 30× change. Stacking them does not close the gap. The residual must come from somewhere else.

Her positive proposal: the residual is rhetorical. The decisive change in 17th- and 18th-century Northwestern Europe was a transformation in how merchants, manufacturers, inventors, and markets were spoken about — a moral revaluation of commercial life that, where it took hold, freed millions of people to act in ways the old contemptuous treatment of trade had suppressed. Pulpits, plays, novels, parliamentary debates, and pamphlet wars are her primary evidence; the case is at once textual-rhetorical and historical-comparative (Song China and Mughal India had material preconditions but lacked the rhetorical revaluation).

The methodological commitments are deliberately non-standard. McCloskey is openly hostile to what she calls “qualculation” — the over-reliance on regression coefficients and statistical significance in mainstream economics — and to the cliometric pretense that quantitative methods are uniquely rigorous. She insists that historical interpretation is irreducibly rhetorical and that pretending otherwise produces bad history. This is a methodological position with which she has prosecuted decades-long arguments inside and outside economic history.

Reception and contestation

The reception is uniquely polarized. McCloskey has serious admirers in economic history (the negative half of the Bourgeois argument — that no one materialist factor closes the explanatory gap — is widely conceded, even by those who reject the positive ideational claim) and serious detractors (the rhetorical-evidence base is hard to falsify; the “no materialist factor explains a 30× change” frame can be made to deflect any specific evidence). Her broader prominence as a cultural figure (her transition in 1995, chronicled in Crossing; her libertarian political commitments; her active public-intellectual writing) has shaped reception in ways orthogonal to the scholarly substance.

Within the IR debate, McCloskey is treated as the canonical statement of the bourgeois-dignity / ideational position. Few practitioners adopt her framework wholesale; most treat her as a productive provocateur whose negative case (the materialist accounts have a residual problem) requires engagement, even when her positive case (rhetoric did the missing work) is held at arm’s length.

Her pre-Trilogy work in cliometric economic history is substantial and continues to be cited: Economic Maturity and Entrepreneurial Decline (1973) on the late-Victorian British steel industry, work on enclosure and English agriculture, methodological essays on economic-history practice. The Rhetoric of Economics (1985) is widely taught in methodology of economics courses.
