The studies’ greatest advantage is that they tend to examine effects on whole industries, including the unlucky or less competent losers, as well as the successes. With microdata, they can look at the characteristics of firms changing ownership as well as those forced out of an industry, those entering, and those remaining. A goal for case studies might be to assemble a collection of unsuccessful ventures and to compare them with successful ones, not only with respect to their own characteristics but also, even more importantly, with respect to country and industry environments.
