Why the global economy is more uncertain than ever, and what to do about it
Briefly

The unpredictability of the future is increasing, exacerbated by wars, political instability, the COVID-19 pandemic, and climate change. While the capacity to predict through AI and data analysis is growing, existing financial and insurance tools are inadequate for extreme uncertainties. Historical frameworks differentiate between quantifiable risks, represented by models like the Black-Scholes, and unpredictable uncertainties that must be addressed for resilience. This difference is vital for tackling global challenges and emphasizes the need for innovative financial instruments to mitigate potential crises.
Many financial markets have developed risk management strategies, but as uncertainties increase, current predictive tools fall short of addressing extreme unpredictability in global systems.
Frank Knight's recognition that risk is quantifiable has led to the development of financial models which help professionals forecast potential outcomes and manage economic challenges.
New financial tools need to be created to effectively hedge against uncertainty, to stabilize global systems against unexpected crises stemming from climate change and geopolitical tensions.
Understanding the difference between risk and uncertainty is essential; while risk can be quantified, uncertainty encompasses unpredictabilities which can jeopardize future planning.
