I was born in Italy but grew up in Germany where I also started studying economics at university. I got my first degree from the London School of Economics and my PhD in economics from Stanford University. I have been an editor of The Economic Journal and on the editorial board of the Review of Economic Studies. I have been the scientific chair of both the main Spanish and the main European annual meetings of academic economists, as well as the director of the economic growth group of the main European network of academic economists. My main university appointments have been at the University of California, Berkeley, at the Universitat Pompeu Fabra, and at the University of Mannheim.
