Whereas microeconomic studies point to pronounced downward rigidity of nominal wages in the US economy, the standard Phillips curve neglects such a feature. Using a stochastic frontier model, we find macroeconomic evidence of a strictly nonnegative error in an otherwise standard Phillips curve...

We show, however, that it may be possible to...

According to one strand of the international finance literature, market efficiency implies that the real exchange rate follows a martingale process, in direct conflict with the long-run absolute purchasing power parity hypothesis, which requires a stationary real exchange rate process. This...
