Christopher Monroe cited Liverani’s work and suggested that the economy of the Late Bronze Age became unstable because of its increasing dependency on bronze and other prestige goods. Specifically, he saw “capitalist enterprise”—in which he included long-distance trade, and which dominated the palatial system present in the Late Bronze Age—as having transformed traditional Bronze Age modes of exchange, production, and consumption to such an extent that when external invasions and natural catastrophes combined in a multiplier effect, the system was unable to survive.10
