Jarvis, Associate Professor Department of Agricultural Economics University of California, Davis PREFACE This research was accomplished as Jarvis' dissertation in 1969. Part of the theoretical and empirical results was I published in the Journal of Political Economy in May/June 1974. These findings have strongly influenced subsequent research on the livestock sector. The Gianinni Foundation is now publishing a revised version of the work as a special report because the dissertation, which has been difficult to access, contains additional methodologies and results which are still of interest: the links between the micromodels treating cattle as capital goods and the specification of the econometric model, the construction and validation of the disaggregated herd series needed to estimate the model, and the detailed interpretation of the empirical findings. The report also discusses technical change in the livestock sector, crop the livestock interrelationships, agricultural labor market developments, and the role of cattle cycles in Argentine macroeconomic fluctuations, all of which are of special interest to students of the Peron era. ·. i' The Giannini Foundation occasionally publishes research as a Special Report. This is in addition to its regular publications series, the Monograph, the Research Report, and the Information Series.
