This paper presents a model that complements the research stream of transaction cost economies with the dynamic capabilities approach. The paper shows that, even though technological alliances involving specific assets deployed in emerging industries are exposed to high transaction costs, they possess attributes that make them attractive. First, they facilitate the creation of tacit competencies, and second, they reduce the uncertainty arising from technological innovation and regulatory changes. The model is empirically tested in the hazardous waste management industry by using primary data collected through the use of questionnaires. The method links governance structure choices to managers' perceptions of the uncertainty surrounding the acquisition of technology. Copyright 1999 by Oxford University Press.
