The paper analyzes the importance of credible institutions in the process of trade liberalization. It combines aspects of credible policy announcements with adjustment costs. We show that if industries' profits are subject to adjustment costs, a dynamic link between periods arises that creates...

In this survey, we critically review the argument for central bank independence (CBI). We argue CBI is neither necessary nor sufficient for reaching monetary stability. First, CBI is just one potentially useful monetary policy design instrument among several. Second, CBI should not be treated as...
