From Burros to Buses: Transport Efficiency and Economic Development in Guerrero, Mexico

The manner in which local communities are embedded within broader regional, national, and international economies, a central theme in contemporary ethnographic research, is heavily conditioned by the prevailing forms of transportation. Major improvements in transport efficiency frequently correspond to equally dramatic changes in the position of communities in their broader socioeconomic environment. This article presents a method of evaluating transport costs that can be used by ethnographers to quantify the magnitude of shifts in relative efficiency. The method and the processes it is designed to elucidate are demonstrated in the case of communities in an agrarian marketing region in southern Mexico. The article attributes divergent patterns of economic development within the region to quantifiable differences in access to particular types of transportation systems.
