The online course Mainline Ecnomics is offered by Institute for Political Studies and International Relations, Universidad Francisco Marroquín. In this course, Roberta Herzberg of the Mercatus Center at George Mason University, discusses "mainline economics.” This approach to the study of economics is characterized by a focus on the modern origins of this field in the ideas of Adam Smith, who emphasized the broader contexts of life, such as politics, institutions, and social interactions. Smith, along with important figures like Friedrich Hayek, James Buchanan, and Elinor Ostrom will help us to analyze how and why individuals make economic decisions.
