On the Credibility of Currency Boards
18 Pages Posted: 27 Oct 2006
The paper compares the credibility of currency boards and (standard) pegs. Abandoning a currency board requires a time-consuming legislative process and an abolition will thus be well-anticipated. Therefore, a currency board solves the time-inconsistency problem of monetary policy. However, policy can react to unexpected shocks only with a time lag, thus the threat of large shocks makes the abolition more likely. Currency boards are more credible than standard pegs if the time-inconsistency problem dominates. In contrast, standard pegs, that can be left at short notice, are more credible if exogenous shocks are highly volatile and constitute the dominant problem.
