Tyler Cowen, author of "GOAT: Who is the Greatest Economist of All Time?", dives into the criteria for determining the most influential economists. He critiques figures like Marx and Samuelson while celebrating lasting giants like Smith and Keynes. The discussion spans the evolution of economics, the balance between liberty and utility, and insights on figures like Malthus and Hayek. Cowen also highlights the paradoxes of productivity during chaotic times and examines the cultural reflections of economic thought, intertwining insights with literature and technology.
Schumpeter's concept of creative destruction emphasizes the transformative power of innovation and entrepreneurship in driving economic growth and progress.
Hayek's notion of emergent order highlights how economies self-organize without central planning, guided by dispersed knowledge and decentralized decision-making.
Friedman's insight on personal incentives sheds light on the limitations of government spending and the importance of individual responsibility.
Keynes advocated for government spending during economic downturns to stimulate demand and lift economies out of depressions, emphasizing the role of active fiscal intervention.
Malthus expressed concern about uncontrolled population growth and urged for conscious limitations on reproduction through moral restraint.
Deep dives
Schumpeter: Creative Destruction
Schumpeter's concept of creative destruction highlights the transformative power of innovation and entrepreneurship in driving economic growth and progress.
Hayek: Emergent Order
Hayek's notion of emergent order emphasizes how complex systems, including economies, spontaneously self-organize without central planning, guided by dispersed knowledge and decentralized decision-making.
Friedman: Spent other people's money
Friedman's insight that people tend to be more careful with their own money than with other people's money sheds light on the limitations of government spending and the importance of personal incentives.
Keynes: Government spending in depressions
Keynes argued that during economic downturns, government spending is vital to stimulate demand and lift economies out of depressions, advocating for active fiscal intervention.
Malthus: Moral restraint
Malthus highlighted the concept of moral restraint, expressing concern that societies lacked the self-discipline to control population growth, and urged for conscious limitations on reproduction.
Mill: Harm principle
Mill's harm principle, encapsulated in his work On Liberty, posits that individuals should be free to act as they please as long as their actions do not harm others, advocating for personal liberty and individual autonomy.
Smith: Invisible hand
Smith's idea of the invisible hand emphasizes that individuals, driven by self-interest, unintentionally contribute to the benefit of society through market interactions and the pursuit of their own economic goals.
The importance of Adam Smith's insights
Adam Smith's contributions to economics, such as the concepts of increasing returns, the role of trade and the division of labor, and the phenomenon of public choice, are still highly influential today. These ideas, along with his depth and breadth of analysis, make a strong case for Smith as one of the greatest economists of all time.
Limitations and criticisms of Adam Smith
While Adam Smith has a strong claim to being the greatest economist, there are some areas where he falls short. Specifically, Smith did not have a strong macroeconomic framework, particularly when it came to marginalism and cycles. Furthermore, his analysis of tax incidence was not as strong as other economists, and his views on trade policy leaned towards mercantilism. Despite these limitations, Smith's overall contributions to the field are still highly significant.
Who is the greatest economist of all time? In Tyler Cowen's eclectic view, you need both breadth and depth, macro and micro. You can't have been too wrong--and you need to be mostly right. You have to have had a lasting impact, and done both theory and empirical work. If you meet all these criteria, you may just be history's greatest economist. Listen as Cowen talks about his new and freely accessible book GOAT with EconTalk's Russ Roberts. Along the way to crowning a winner, Cowen offers original insights into what shaped the theories and worldviews of the greatest economists of all time. Cowen and Roberts also talk about the evolution of economics from a field concerned mainly with ideas to one that mostly grapples with empirical challenges.
