Profile analysis, nonmetric multidimensional scaling and clustering techniques were used to create two\u2010dimensional maps displaying the changing relationships among 41 authors as perceived by scholars citing their work over the two time periods. Clusters of points on the map, representing authors, correspond to theory groups or research areas. Authors in Rational Expectations Theory, Implicit Contracts, and a general group labeled \u201cPost\u2010Monetarist\u201d show a marked increase in mean cocitation rate. The first is a school of thought emerging as a new focal point of scholarly activity in Macroeconomics.
