This particular volume required a long period of gestation. I began background research on human resource development in Puerto Rico over ten years ago. My first published paper in this area appeared in 1981. After continued work on issues relating to industrialization and human resources in Puerto Rico, it became imperative to integrate this body of research into a cohesive whole. This required reassessing past work in light of new experiences. Discussions with colleagues on their own research in this area were also fundamentally important.
Along the way I have been assisted by many colleagues and friends, both economists and noneconomists, who have helped me understand the complexities of the Puerto Rican economy. To them I owe a great deal. I should particularly mention Erik Thorbecke, who has served as the principal proponent of the multi- sectoral framework of Chapter 2. Jim Dietz has encouraged me to broaden my focus of inquiry and cautioned me on the limitations of applying neoclassical analysis to social and historical phenomenon. Rosemary Rossiter introduced me to multiple time series models and extended my knowlege of econometric and statistical tools for the analysis of time series. I would also like to acknowledge the generous institutional support I have received, at different stages of my work, from Cornell University, Wayne State University, Yale University, and the the State University of New York at Albany. Generous financial support has also been made available to me by the Rockefeller Foundation, the Ford Foundation, the Inter- University Program for Latino Research, and the Social Science Research Council.
