The Feedback Effects of Sovereign Debt in a Country’s Economic System: A Model and Application

Many of the existing theoretical and empirical studies ignore the two-way relationship between a sovereign’s credit risk and economy. To address this gap, we develop a theoretical model that incorporates the feedback effects of sovereign-debt credit risk on a country’s economy and then provide empirical implications. The model links the risks of sovereign debt and economic fundamentals through a two-way transmission mechanism. In doing so, it demonstrates how economic-fundamentals-driven sovereign-debt credit risk can have a significant impact on economic fundamentals through a feedback effect that has the potential to significantly raise the sensitivity of a country’s economic performance to shocks from both the credit risk associated with sovereign debt and economic fundamentals.
