Description
Summary:This essay is a historical and epistemological exploration of a traditionally crazy economic event: the financial bubble. Venturing into two different moments in the history of economic thinking, it investigates financial bubbles as epistemic frontiers, where rationality has reached its limits. The first half forays into late twentieth-century economics. Since 1980, an interpretive battle over the ir/rationality of bubbles has made those peculiar events, long beyond the pale of the rational, contested terrain on which the limits of rationality have been fought out. The essay’s second half turns to one historical crisis, the South Sea Bubble. For contemporaries in 1720, the bubble was a different kind of epistemic frontier. As they tried to reckon what South Sea Company stock was worth, investors were confronted not with clearly rational or irrational choices but with a decidedly unruly collection of similarly plausible calculations. The story of 1720 suggests that studying historical confusion might be a profitable enterprise for scholars of the economic and epistemological past.
