Indeed, a trade boom followed over the subsequent three centuries. But what was its cause? The conventional wisdom in the world history literature offers globalization as the answer: it alleges that declining trade barriers, falling transport costs and overseas 'discovery' explains the boom. In contrast, this paper reports the evidence that confirms unambiguously that there was no commodity price convergence between continents, something that would have emerged had globalization been a force that mattered. Thus, the trade boom must have been caused by some combination of European import demand and foreign export supply from Asia and the Americas. Furthermore, the behavior of the relative price of foreign importables in European cities should tell us which mattered most and when. We offer detailed evidence on the relative prices of such importables in European markets over the five centuries1350-1850. We then offer a model which is used to decompose the sources of the trade boom 1500-1800. ER -
