Washington, Mar 10: Rising income inequality may be encouraging governments to maintain higher levels of sovereign debt, as access to international borrowing helps finance income redistribution without relying heavily on higher taxes, according to a new study by the International Monetary Fund (IMF).
The research, published as an IMF working paper by economist Monica Tran-Xuan of the IMF’s Research Department, suggests that government borrowing plays a broader role beyond managing economic crises.
It may also help policymakers address the economic challenges of redistributing income in societies experiencing growing inequality.The study notes that in recent decades many countries have seen a simultaneous rise in income inequality and external debt.
Governments often respond to fiscal stress or economic downturns through austerity measures such as tax increases or spending cuts, which can disproportionately affect low-income households.In such situations, policymakers face the difficult task of maintaining fiscal stability while protecting vulnerable sections of society through redistribution policies.
The paper explains that most governments redistribute income through taxation and public spending, where taxes collected from higher-income groups help fund social programmes for lower-income households.
However, these redistributive policies can create economic distortions. For instance, heavy reliance on labour taxes may discourage work and reduce productivity if tax levels become too high, potentially slowing economic growth.As a result, governments must balance the need to reduce inequality with the risk of excessive taxation harming economic activity.
According to the study, borrowing from international financial markets can help governments ease this trade-off. External borrowing allows governments to fund redistribution programmes without immediately raising taxes, effectively spreading the cost over time.This flexibility can help sustain economic activity while maintaining social spending, the study said.
The research also offers insights into why countries often choose to repay sovereign debt even during periods of economic stress. A sovereign default typically results in a country losing access to international financial markets, a condition referred to as financial autarky. Without the ability to borrow externally, governments must depend entirely on domestic taxes to fund public spending and redistribution programmes.
This could force governments to significantly increase labour taxes, which may reduce employment, lower output and worsen economic conditions, the study noted.Because of these potential economic costs, governments may prefer to continue servicing their debt rather than default and lose access to global credit markets.
The study concludes that societies with higher levels of inequality may have stronger incentives to maintain higher sovereign debt, as international borrowing enables governments to sustain redistribution policies while limiting the economic impact of higher taxes.
