The research on which this book is based was financially supported by a grant from the Social Sciences and Humanities Research Council of Canada. The Council's long-term support is gratefully acknowledged. Additional support was provided by the University of Winnipeg and Canadian Policy Research Networks.
The data analysis is based on a Statistics Canada microdata tape containing anonymized data collected in the 1992 Family Expenditure Survey, as well as a U.S. Bureau of Labor Statistics microdata tape containing anonymized data collected in the 1992 Consumer Expenditure Survey. All computations on these microdata were prepared by David Cheal. The responsibility for the use and interpretation of these data is entirely that of the author. Data analysis, as well as the preparation of tables and figures, was assisted by Karen Kampen. Her energy and her desire to learn were vital to the completion of many different undertakings.
Some of the early theoretical work for this book benefited from invitations to speak at the Theory Construction and Research Methodology Workshop at the 1992 Annual Conference of the National Council on Family Relations in Orlando and at a conference on family sociology in Oslo in 1994. The latter conference arrangements were made possible by a grant from the Research Council of Norway. I would like to thank Arnlaug Leira for agreeing to the use made in this book of portions of the paper presented on that occasion.
