Impact of wage rigidity on sovereign credit rating

Sovereign credit rating is a condensed assessment of a country's ability to repay its public debt in a timely fashion. Downward wage rigidity has been considered as a critical determinant of various macroeconomic and financial phenomena. This study examines the effect of a country's wage rigidity on its sovereign credit rating after measuring downward wage rigidities based on a regime-switching model. The results indicate that greater wage rigidity induces lower sovereign credit rating. We find that wage rigidity amplifies cash flow fluctuations and magnified cash flow volatility negatively affects sovereign credit rating. (C) 2017 Elsevier B.V. All rights reserved.
