Based on the transaction cost reasoning this doctoral dissertation proposed a model that theorizes on the relationship between uncertainty, bounded rationality, asset specificity, opportunism and vertical integration in supply chains. An extensive literature review was conducted in three basic fields: transaction cost economics; organizational theory; and strategy to better understand the definition of those variables and their theoretical relationship. The review also helped to identify scales used in previous research to measure the research variables. The identified scales were then back translated and adapted to be used in this research. The research instrument was pre-tested and then it was made available on the internet from April to October 2008 and managers from industrial organizations classified in the D section in the Brazilian SIC and also listed in the database of FIESP (São Paulo State Industry Association) were asked to participate in the survey. The section D includes industries that perform physical, chemical and biological transformation of inputs into new products. From the population we selected only firms classified by the association as medium or large sizes which resulted in a target of three thousand potential subjects. Electronic messages which explained the survey proposal and instructions to fill in the questionnaire were sent through the internet. All those that not answered the first message received another message few days later and they were again contacted by phone. Due to the nature of the study only middle managers and directors working in the target firms were asked to answer the questionnaire. Some 111 good responses were available in the end of data collection process and they represent 87 different firms and 14 economic activities the collected data were analyzed using the EQS 6.1 software, which allowed the validation of the research constructs through SEM. The use of this methodology represented an innovation in the research field, because it gives the possibility to include more variables in the basic model, and they are simultaneously considered in the search of explanations for vertical integration. This choice brought important methodological contributions to the research field. Validation of the uncertainty construct as multidimensional derived from three types of uncertainty. The second contribution was to test the construct bounded rationality as a second order latent variable and in the first order were used two types of uncertainty effect and response. The third contribution refers to the level of refinement introduced by the use of the EQS software and structural equation modeling. This approach allowed us to verify the validation of the theoretical model. The statistical significance of most tested direct and indirect relationships among constructs confirmed the proposed theoretical model. Another finding derived from the data is that the explanation of degree of vertical integration in supply chain has to consider all research constructs included in the model to interact together. So no single construct in the TCT can explain alone the vertical integration.
