True/False/Uncertain - Briefly explain.

1. Theoretically, monetary unions should lead to more asymmetric shocks.

2. Pricing to market would lead to more price convergence in a monetary union.

3. More trade integration, even with less symmetry, can make a monetary union optimal.

4. With expected devaluation, an intermediate shock would not result in devaluation.

***I need help with this sort of problem. We use the book Economics of Monetary Union 12th Edition

by Paul De Grauwe. Which chapter should I read to understand the above questions? I want to improve at solving this, so please let me know.

Thank you.
