Abstract: This article observes that current macroeconomic policy modeling, centered on domestic agents or agencies, fails to recognize the role that global investors play in determining the space for effective domestic macroeconomic policies, and argues that these actors must be brought to the center of macro analysis if one wants to understand how policies work in the global financial context. The article describes the key features of global investors, discusses their power to determine the prices at which public-sector liabilities (money and debt) trade in the international markets, and considers how this power affects the effectiveness of macroeconomic policies by national governments. As a result, no government is truly sovereign in a globalized world, and every government is subject to an intertemporal budget constraint (IBC), although, of course, not all governments are born equal and not all IBCs are equally binding: government IBCs are elastic, endogenous to global investor decisions, and yet ineluctable. The article concludes that choosing the correct country policy stance in today's financial global context would benefit from revisiting some of the key policy lessons that John Maynard Keynes left with us, considering his deep knowledge of global financial markets and how they affect country economies.
