They wrote of their observations and suggested ways family businesses could avoid some of the pitfalls that the authors had observed confronting their clients. Currently, the majority of family business articles are of this type (Swartz, 1989). Similarly, there are many articles that have stated the contributions of family businesses to the GNP and to employment, much as entrepreneurship and small business writers have done and continue to do. Problems include a lack of secondary data sources, forcing researchers to conduct field research studies. Field studies, in turn, are difficult to achieve because of the family business owners’ lack of interest in participating in such studies, the wide spectrum of family businesses, the lack of theories for hypothesis testing, and the lack of commonly accepted definitions of an entrepreneur or a family business.
