Economics Should Go Back to Its Basics for a Fast-Changing World

The current global economic landscape, marked by frequent disruptions in supply chains and growing political polarization, underscores the need for a fundamental re-evaluation of economic theories and practices. Historical precedents suggest that paradigm shifts in economic thought are essential during times of significant technological and societal changes.

Challenges in Contemporary Economic Thought

• Inadequacy of Current Models: Despite an abundance of data, mainstream economic thinking and policymaking are failing to address the complexities of today's world. Critics argue that the focus on mathematical models has detracted from the field’s practical applicability to public policy.
• Need for Paradigm Shifts: Major turning points in history, such as the Industrial Revolution, necessitated new economic theories to understand and manage the resulting societal changes. Similarly, the digital revolution and artificial intelligence today demand a rethinking of economic fundamentals.
• Interconnected Issues: The separation of economics from political science has created an artificial divide that hinders a comprehensive understanding of modern global issues. The rise of game theory offers a framework to bridge this gap, integrating political and economic analysis.

Historical Context and Lessons

• Industrial Revolution Insights: The Industrial Revolution brought about significant changes in production and labor, prompting pioneering works like Adam Smith's "The Wealth of Nations" and Léon Walras’s "Elements of Pure Economics." These works laid the groundwork for necessary policy interventions and economic reforms.
• Shift to Neoclassical Economics: Following Walras, economics became more focused on mathematical modeling, which initially served public policy well. However, the assumption of perfect information embedded in neoclassical economics proved to be unrealistic.
• Information Asymmetry Breakthroughs: Economists like George Akerlof, Joseph Stiglitz, and Michael Spence highlighted the impact of asymmetric information, challenging core neoclassical assumptions and leading to policy changes that better protected consumers and workers.

Implications of the Digital Revolution

• Redefining Labor and Trade: The digital revolution and AI are transforming labor markets and international trade, creating new forms of economic interactions and conflicts. Policymakers need to recognize these changes and adapt accordingly.
• Firefighting vs. Structural Change: Current economic policies often react to crises rather than addressing underlying systemic issues. Just as developing non-flammable materials is better than firefighting, economic policies should aim for long-term resilience.
• Reviving Political Economy: Returning to the classical tradition of political economy can provide the necessary tools to understand and navigate the complex interplay between economics and politics in the modern world.
