5-Hydroxytryptophan: a clinically-effective serotonin precursor.

5-Hydroxytryptophan (5-HTP) is the intermediate metabolite of the essential amino acid L-tryptophan (LT) in the biosynthesis of serotonin.

Unlike LT, 5-HTP cannot be shunted into n...

Purchasing power parity and real effective exchange rates

This study re-examines the validity of Purchasing Power Parity (PPP) by focusing on the real effective exchange rates (REERs) for the post-Bretton Woods period, using newly developed unit root tests that account for both nonlinearity and smooth temporary multiple breaks in the data. The tests are applied to the REERs of 23 developed countries and are able to reject the null hypothesis of a unit...
