a b s t r a c tThis study empirically examines the effects of a regulation change on the structure and governance of leveraged buyouts (LBOs) within the Italian private equity market, whose transactions were only recently legalized. With a new data set covering approximately 85% of the buyout funds active in Italy during the period of 1999-2006, we find that a regulation that prohibits LBOs can reduce their frequency, but does not exclude them altogether. Rather, it inhibits efficient governance and distorts decision making. Overall, the data are consistent with the view that laws prohibiting LBOs result in less efficient LBO arrangements.
