The econometric model applied was the linear and ordered models to explain the explanatory variables. The results show that GDP per capita, Investment, General Public Debt, Unemployment, Government Revenue, and Governance may have a steady impact on sovereign ratings.engSovereign debt ratingsratings agencieslinear modelsordered modelsmaster thesis
