Income inequality in central Spain, 1690-1800

This paper studies the evolution of income inequality in central Spain during the late seventeenth and eighteenth centuries, taking as case study the province of Guadalajara. The first part of the paper presents the sources and the dataset that was created to estimate income inequality using grain tithes. The second section shows that through the period grain represented the lion share of total income and therefore that it can be used as a reliable proxy. The following part of the paper introduces an analysis of income inequality in the province during the period 1690-1800 and concludes that inequality decreased during the last third of the eighteenth century. Finally the paper addresses this unexpected result and concludes that it was consequence of the success of the land reform carried out by the central government in the late 1760s. The reform was a success in Guadalajara thanks to the characteristics of its population and the lack of bargaining power of pressure groups.Agrarian history, Inequality, Pressure groups, Institutions

Amartya Sen revisited: trade, inequality and growth in central Spain, 1700-1800

This paper studies the effects of trade and inequality in central Spain during the eighteenth century, taking as case study the province of Guadalajara and the surrounding regions. The first part of the paper presents a specific factors model as theoretical framework that will later be applied to the empirical data. The second part introduces an analysis of income inequality in the province during the eighteenth century and concludes that inequality decreased, especially during the last third of the century. Finally the paper addresses this unexpected result and concludes that it was consequence of the success of the land reform carried out by the central government in the late 1760s. The reform was a success in Guadalajara thanks to the characteristics of its population and the lack of bargaining power of pressure groups. Following Sen’s ideas, the reduction in inequality meant that markets could work properly and that a majority and not only a few could take full advantage of the benefits of trade.Trade, Inequality, Pressure groups, Institutions

Tithe series and grain production in modern Spain: Guadalajara 1700-1800

The following paper presents original tithe series for the province of Guadalajara in New Castile. The series include the four main grains, wheat, barley, rye and oats and their evolution during the eighteenth century. The series complete previous estimations of grain production for New Castile and suggest that the eighteenth century was a period of growth. However the increase was not a sustained process, but one with intense imbalances with production reaching its peak in the mid 1750s followed by a deep crisis and very weak recovery. Wheat was clearly the most important of the four grains in volume and especially in value. Its predominance was maintained thanks to a demand encouraged by the demographic that took place during the eighteenth century. A comparison with other tithe series from the interior of Spain reveals similarities like the crisis of the late 1750s.Tithe, Agricultural output, Spain

Embedded Sensor System for Early Pathology Detection in Building Construction

Structure pathology detection is an important security task in building construction, which is performed by an operator by looking manually for damages on the materials. This activity could be dangerous if the structure is hidden or difficult to reach. On the other hand, embedded devices and wireless sensor networks (WSN) are becoming popular and cheap, enabling the design of an alternative pathology detection system to monitor structures based on these technologies. This article introduces a ZigBee WSN system, intending to be autonomous, easy to use and with low power consumption. Its functional parts are fully discussed with diagrams, as well as the protocol used to collect samples from sensor nodes. Finally, several tests focused on range and power consumption of our prototype are shown, analysing whether the results obtained were as expected or not
