The currency dilemma

When a currency is devalued, the exports of the countries look more attractive to other countries with stronger currencies. But this strategy can touch off inflation in the exporting countries.
China devalued its currency from time to time to continue to make exports attractive. This strategy was a sound one due to the large number of people who participate in an economy based upon barter (the informal economy). But it can backfire if several families and households send workers away to work, and to bring home money; because bringing home a medium of exchange that will be worth less tomorrow than today is the main characteristic of inflation on that medium of exchange. As more and more families are included in the formal economy, one will have to wonder how that problem will be addressed--whether it is fiscal, monetary or both types of policies that will be put into play to regulate a burgeoning marketplace.
