We analyse the rate of formation, the characteristics, and the performance of different types of new firms in Sweden over a decade. Comparisons with Denmark, Brazil, and the United States suggest that the environment for new firm formation in Sweden is not markedly different than elsewhere. In line with previous studies, spin-offs of incumbents perform better than other types of new firms, particularly if their parent firm continues to operate. A novel finding is that the larger the size of their parent, the greater is the rate of employment growth of spin-offs. This contrasts sharply with findings for firms with a single owner.
