Description:
We investigate whether political similarities between credit rating agencies (CRAs) and bond issuers impact credit rating quality. We find that a higher degree of similarity of political affiliation leads to a decrease in timeliness and accuracy of downgrades prior to default events. Our finding supports the notion that CRAs tend to maintain/assign preferential ratings to politically similar firms via delaying negative signals as favourable rating activities. We further show that these politically similar firms tend to increase the proportion of donations to their favoured party following favourable credit ratings. Interestingly, this result is confined to Republican-leaning firms. The results indicate that CRAs successfully use biased credit ratings as an indirect channel of political party support. Our findings support the politically motivated credit ratings hypothesis
