Classical political economists like Adam Smith or David Ricardo never used the term “economy” by itself. They always used the term “political economy.” For classical economists, it was impossible to understand politics without economics or economics without politics. The two fields are certainly different but they are also intimately linked. The use of the term “economy” by itself did not begin until the late 19th century. Smith understood that while an efficient market would emerge from individual choices, those choices were framed by the political system in which they were made, just as the political system was shaped by economic realities. For classical economists, the political and economic systems were intertwined, each dependent on the other for its existence.
