Williamson, Jeffrey G.2006-11-092006-11-092005-10https://hdl.handle.net/10016/393Between 1810 and 1940, a large GDP per capita gap appeared between the industrial core and the poor periphery, the latter producing, increasingly, primary products. Over the same period, the terms of trade facing the periphery underwent a secular boom then bust, peaking in the 1870s or 1890s. These terms of trade trends appear to have been exogenous to the periphery. Additionally, the terms of trade facing the periphery exhibited relatively high volatility. Are these correlations spurious, or are they causal? This Figuerola Lecture, to be given at Carlos III University (Madrid) , argues that they are causal, that secular growth and volatility in the terms of trade had asymmetric effects on core and periphery. On the upswing, the secular rise in its terms of trade had powerful de - industrialization effects in the periphery. Over the full cycle 1810-1940, terms of trade volatility suppressed accumulation and growth in the periphery as well.134563 bytesapplication/pdfengAtribución-NoComercial-SinDerivadas 3.0 Españaworking paperEconomíaHistoriaopen accessdilf0506
