This paper has presented a descriptive analysis of the shifting patterns of productive output and topical coverage in the
economic-journal literature over the last two decades. Summary results suggest that research interests have not been stagnant.
In fact, the analysis reveals that economists' research interests have tended to shift direction as society's economic problems
change.
The economics profession is still productive, with growth rates in research output similar to those prior to 1968. Also, the
increase in the incidence of co-authorship suggests that perhaps we are smart enough to exploit comparative advantages. The
profession's research output is probably best described by a saying credited to Jacob Viner, “Economics is what economists
do.” One can safely state that this definition has not significantly changed.
