Les recherches sur la contribution des Business Angels (BA) à la croissance de l’économie sont encore récentes et relativement peu diffusées, en France notamment. Afin de comparer la dynamique d’entreprises adossées à des BA à des entreprises qui ne le sont pas, nous proposons une...

A multivariate analysis can be used in order to investigate the relationship between bond yields, ratings and standard control variables. Replicating such a test on a number of cross-sections may evidence a possible impact of financial regulations relying on ratings. Datasets for American...

Historical accounting datasets about a leader of the bond rating industry have been gathered in order to provide an unprecedented long term view on this business. To better judge of the dynamics at play, similar data for representatives of older and broader business fields is also introduced....
