Heterodox economics: Marginal revolutionaries
POINT UDALL on St Croix, one of the US Virgin Islands, is a far-flung, wind-whipped spot. You cannot travel farther east without leaving the United States. Visitors can pose next to a stone sundial commemorating America's first dawn of the third millennium. A couple named “Sigi + Ricky” have added a memento of their own, an arrowstruck heart scrawled on the perimeter wall in memory of “us”. Warren Mosler, an innovative carmaker, a successful bond-investor and an idiosyncratic economist, moved to St Croix in 2003 to take advantage of a hospitable tax code and clement weather. From his perch on America's periphery, Mr Mosler champions a doctrine on the edge of economics: neo-chartalism, sometimes called “Modern Monetary Theory”.
