Abstract:
Yen-dollar fluctuations increase macroeconomic instability in small economies in East Asia. I investigate the choice of an exchange rate regime for these countries so as to minimize the adverse effects of this volatility. I build a sticky-price dynamic model of a small economy whose trade is invoiced in dollar and yen. First, I show the conditions under which pegging to a tradeweighted basket of the two currencies is the optimal policy for the small economy. Then, I introduce net worth constraints and unhedged dollar borrowing which pull the optimal policy away toward putting a much greater weight on the dollar.
