A self-exciting threshold autoregressive model is used to measure transaction costs that may explain relative price differentials and nonlinearities in the behavior of sectoral real exchange rates across Mexico, Canada and the U.S. Interpreting price threshold bands as transactions costs, we...

During the last decade, economists have intensively searched for evidence on the importance of the Balassa-Samuelson (B-S) hypothesis in explaining nominal convergence. One general result is that B-S can at best explain only part of the excess inflation observed in the European catching-up...
