During the hundred-year period from about 1320 to about 1420, the Florentine woollen cloth industry underwent two closely connected crises. The first crisis was the consequence, direct and indirect, of the ravages of warfare and falling population, afflicting the entire Mediterranean basin and...

A recurrent and indeed persistent problem in European economic history – a veritable deus ex machina -- from medieval to modern times, is Europe’s supposed ‘balance of payments’ problem in trade with the ‘East’. This supposed problem has often been couched in Mercantilist overtones:...
