Les serranos et le pont de Capilla au XVème siècle

Despite a few pioneering studies into transhumant raising in the kingdom of Castile much work in this field has yet to be done. We are acquainted with its general organisation but more rarely with its local manifestations. On the whole we know of the revenues it yielded to the Crown but less of those it delivered to the lords. It was during a lawsuit brought by the Mesta at the end of the fifteenth century against the lord of Capilla, whom it accused of imposing illegal taxes upon the migration of the winter herds across the Capilla bridge on their way to the Extranadura of the south, that a rich documentation was collected by the incriminated party. This documentation holds a twofold interest for us: first it informs us about the region of origin of the animals which followed this migration, the number of herds involved, their composition and their owners and shepherds; second it gives us knowledge of the revenues which a lord could extract from the collection of taxes imposed on the migration, or transhumance, itself.     

TRANSBOUNDARY INCOME AND EXPENDITURE FLOWS IN REGIONAL INPUT-OUTPUT MODELS*

ABSTRACT. Nearly all regional input-output models have been constructed without a proper accounting of inflows and outflows of personal income and personal consumption expenditures. Typically invoked is a no cross-payments assumption, analogous to the no cross-hauling assumption for commodities. We present a new accounting framework based on the classification of flows according to the location of income generation, receipt, and spending, and argue that only flows endogenous in all three respects should be part of a closed regional I-O model. We use the framework to compute the upward bias in multipliers in a typical regional I-O model. We also present several methods for estimating transboundary flows.
