The wisdom of classical political economy in economics: incorporated or lost?

Is everything good in political economy incorporated into modern graduate education in economics? With the transition of the art of political economy into the science of economics, there was a significant narrowing of graduate education curriculum. The prevailing technique in economics, a neoclassical framework focusing on formal empirics, gradually compressed artistic components of economics, including philosophical underpinnings, democratic justifiability, theoretical intuition, comparative institutional analysis, and political economy. Courses on the history of economic thought, which historically played a role in introducing graduate students to the complexities of the art of political economy, are now only offered as an elective. This paper argues, however, that there are still insights to be gleaned from studying the classics of political economy in graduate education. We highlight the tradeoff between theoretical cumulativeness and knowledge, arguing that significant insights from historical works of political economy are often absent in contemporary technical expositions of economics. We explore examples of useful knowledge in political economy that was lost in the transition away from the art of political economy. To remain an operationally valid social science, economists should reintroduce the artistic elements of political economy into the graduate training of economists. [ABSTRACT FROM AUTHOR]
