Dollarization dynamics: A comment
We analyze a recent paper that claims that dollarizing an economy in the presence of a “dollar shortage” will provoke an immediate sharp reduction in real output and welfare. We find many problems with the model that supports this conclusion: confusion about the nature of a dollar shortage and its practical implications, invalid assumptions, invariant calibration in the presence of a regime change and lack of empirical testing. In our opinion, the paper does not make a valuable contribution to the dollarization debate nor provide useful guidance to policymakers.
