The long decline of a leading economy: GDP in central and northern Italy, 1300-1913

The purpose of the article is to present the statistical reconstruction of a series of per capita output in central–northern Italy between 1300 and 1913. The various phases of both the statistical procedure and the results are presented and discussed.
