The data presented in this article are related to the research article entitled “ Do shareholder coalitions affect agency costs? Evidence from Italian-listed companies ” , Research in International Business and Finance , Forthcoming (Rossi et al., 2018) [1]. The study shows an empirical analysis using an extensive balanced panel dataset of 163 Italian listed companies for the period 2002 – 2013, which is a sample yielding 1956 fi rm-year observations. The sample consists primarily of manufacturing fi rms, but also includes some service enterprises. However all fi nancial fi rms and regulated utilities are excluded. We collected data on ownership structure for the entire study period. Information was acquired from the Consob website and the individual company reports on corporate governance. Data on fi rm-level indicators (debt-to-capital ratio, fi rm size, and age of the fi rm) for all companies in the sample were collected from Datastream, Bloomberg , and Calepino dell ’ Azionista , as well as obtained manually from the fi nancial statements of the individual companies being studied. Our dataset contains several measures of ownership structure for Italian listed companies.
