Fifth, governments in industrialized countries have little trouble in financing their deficits, whereas governments in developing countries typically face greater financial constraints. In fact, experience suggests that few developing countries can sustain a government deficit that is 5% of GDP, or more, for long. Of course, borrowing from the central bank is an option. But it cannot be stretched beyond limits for that could be dangerous. Indeed, such excessive deficit financing was an important source of hyperinflation in several Latin American economies. Consequently, most governments in developing countries run pro-cyclical fiscal policies.17 The financial constraints facing governments exacerbate problems that arise in the private sector. In such a context, underdeveloped financial markets, or inadequately developed financial sectors, impede the ability of developing countries to absorb shocks.
