How does Obstfeld's theory apply to global debt today?
My intertemporal framework is directly relevant to understanding today's high levels of global debt. It emphasizes that current borrowing reflects expectations about future repayment capacity. Policymakers must consider not just the immediate financing needs but also the long-term implications for fiscal sustainability and economic growth. Analyzing debt accumulation through the lens of optimal saving and investment decisions helps assess its true economic burden and the risks associated with its servicing.
