We assemble a dataset on technology adoption in 1000 Bc, 0 Ad, and 1500 AD for the predecessors to today’s nation states. Technological differences are surprisingly persistent over long periods of time. Our most interesting, strong, and robust results are for the association of 1500 AD technology with per capita income and technology adoption today . . .
We assemble a dataset on technology adoption in 1000 BC, 0 AD, and 1500 AD for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Although our strongest results are for 1500 AD, we find that even technology as old as 1000BC matters in some plausible specifications.

This paper models the product cycle and explains how it relates to world inequality. In the model, both phenomena arise because skilled people have a comparative advantage in making high-tech products. The model can explain up to a 10:1 income differential between people and up to a 7:1 differential between countries. Tariff policies and intellectual-property protection have a much larger effect here than in some other models . . .
