α: calibrated so average coauthorship-adjusted count equals average raw count
We estimate a threshold autoregressive model to assess medieval financial integration. Our approach is based on the analysis of deviations between exchange rates and parity, which in a fully integrated market should not exceed bullion points. Hence, the time needed for adjustment, following a violation of the bullion points, is a measure of integration. We apply this approach to exchange between fourteenth- and fifteenth-century Flanders, Lübeck, and Prussia, results showing that whereas it took about eight months to reduce deviations between Flanders and Lübeck by 50 percent, those between Flanders and Prussia were roughly twice as persistent.
