Abstract :
Donald F. Gordon hypothesized that mathematical complexity in economics is inversely related to operationalism. Here we (i) operationalize Gordonʹs hypothesis, (ii) test for the significance of trends in complexity for the American Economic Review, Economic Journal, Journal of Political Economy, and Quarterly Journal of Economics, and (iii) test Gordonʹs hypothesis by conducting analyses of the contents of articles from the American Economic Review (AER), as well as the contents of articles citing the AER articles. The results do not refute the hypothesis that complexity crowds out operationalism in economics. Additionally, the presence of significant, positive trends toward complexity suggests that the magnitude of the crowding out is on the rise in these journals.
