This article analyses the determinants associated with the use of the Integrated Report as a corporate reporting model for sustainability information. IRs provide information regarding the use and interdependence of different company resources. The previous literature has identified determinants behind the presentation of IRs at the country level as well as at the company level. Our work contributes to the literature by using a novel statistical approach that addresses the likelihood of the non-independence of data: companies in the same country (...) are more similar to one another than are companies from different countries. Our results confirm significant inter-country variance, which may be partially explained by the existence of specific regulations and the individualism vs. collectivism dimension. Although we confirm the effect of company-level determinants, our results do not support the role of specific variables tested as determinants. (shrink)
