Explaining vineyard specialization in the province of Barcelona (Spain) in the mid-19th century

Abstract

We present a statistical model of agrarian vineyard specialization in the province of Barcelona towards 1860, that combines the Boserupian push of population increase, the demand pull of a Smithian-type of growth (measured by the time-distances to the nearest seaport), and the agrological lands suitability for sowing grain or growing vines (as measured by water stress, slopes and frost risk). The overall outcome of the adjusted R2 levels, which range from 0.608 to 0.826, can be considered very successful. The inequality in land ownership is another factor that we believe to have played an important role, but has had to be omitted for the moment due to the lack of statistical data. Further research is also needed to deal with a possible endogeneity problem that working with socio-demographic variables entails.wine international market integration, regional land-use patterns, vineyard specialization, population pressure, agrological suitability
