Alexandra de Pleijt is a Postdoctoral Research fellow in economic history at the University of Oxford. 

She analyses long-run economic growth within Europe. Recent research studying patterns of per capita GDP between 1300 and 1900 has shown that, in Holland and Britain, the classic period of the Industrial Revolution was preceded by an earlier growth spurt. Between 1300 and 1700, levels of per capita GDP had already doubled. In her research she studies the drivers of this phase of pre-industrial growth. For instance, together with Professor Broadberry, she provides annual estimates of capital formation and the stock of physical capital in Britain and Holland to provide growth accounts for both countries over the very long-run.  

Alexandra is also studying the relationship between human capital formation and industrialisation, for which she focuses on Britain during the period of the Industrial Revolution.
