What challenges will China have to surmount in order to make its currency a true international currency? To answer this question and others, Barry Eichengreen studies history. In the old days, he says, historians and theorists worked smoothly together and saw one another as serious scholars. But those days are gone, and nowadays the profession largely neglects historical and institutional research. That’s why Barry Eichengreen is running the Berkeley Economic History Lab to educate a future generation of scholars — a generation that is historically literate and does policy-relevant research. These are the seeds of new economic thinking.
