Amar Bhide touches on the unpredictable consequences of devaluations while commenting on the supposed benefit of a country having its own currency vs a currency such as the euro. The euro takes away the advatantage of devaluing the national currency as a way to regain competitiveness. Bhide points out that devaluations hurt the elderly on fixed incomes and low wage workers. Protections have to be put in place for the sections of the population that are badly affected. Large union negotiated wage increases can also reduce the benefits of devaluation in terms of regaining competitiveness.
