TRANSPORTATION RATES AND LOCATION OF THE FIRM: A COMPARATIVE STATIC ANALYSIS*

ABSTRACT This paper examines the role of the structure of transportation rates in the Weber-Moses triangle model. It shows that, in Zeigler's analysis, the appearance of the price elasticities of demand for inputs actually vanish by a simple application of the envelope theorem. Applying comparative statics analysis, we show when transportation rates are a function of quantity and distance, the assumptions that the production function is homogeneous of degree one and the transportation rates elasticities with respect to quantity and distance are constant are not sufficient to insure that the optimum location is independent of the level of output. This result is significantly different from that obtained by either Miller and Jensen or Zeigler.

Race,Gender, Science and Citizenship

This paper argues that the history of embodiment of human racial and gendered differences must be seen as part of the history of liberal citizenship and its limits. The author suggests that a science of similarity and difference can never be a reliable guide to questions of rights. The consequences of this conclusion for our understanding of science and the gendered body are addressed in the second half of the paper, in an effort to clear the way for a more adequate and inclusionary model of citizenship and rights.     

Discovering the invisible Puerto Rican slave family: demographic evidence from the eighteenth century

Traditional notions that family life among slaves during the pre-plantation period in the non-Hispanic Caribbean was necessarily unstable are fading in light of new research. Although marriage among this segment of the population in Caguas, Cayey, San Germán, and Yauco--rural parishes in Puerto Rico--involved only a fraction of the overall number of marriages in these communities, the marriage of slaves was much more frequent than previously assumed. Family life among the eighteenth-century Puerto Rican slave population appears to have been quite stable, as shown by the reconstruction of birth intervals for both married and unmarried mothers. Married and unmarried mothers exhibited similar reproductive behavior. These results strongly suggest that a majority of the unmarried slave mothers lived in unions that were not institutionally recognized, but that were nevertheless stable, as indicated by the high percentage of their children born at intervals comparable to those of married mothers. If unmarried mothers were living in stable consensual unions, then our understanding of these slave family units during the colonial period must be reassessed not only for Puerto Rico but possibly for the rest of the Caribbean and Latin America.
