Nonlinear Exchange Rate Models: A Selective Overview
Description: This paper provides a selective overview of nonlinear exchange rate models recently proposed in the literature and assesses their contribution to understanding exchange rate behavior. Two key questions are examined. The first question is whether nonlinear autoregressive models of real exchange rates help resolve the "purchasing power parity (PPP) puzzles." The second question is whether recently developed nonlinear, regime-switching vector equilibrium correction models of the nominal exchange rate can beat a random walk model, the standard benchmark in the exchange rate literature, in terms of out-of-sample forecasting performance. Finally, issues related to the adequateness of standard methods of evaluation of (linear and nonlinear) exchange rate models are discussed with reference to different forecast accuracy criteria.

The Corporation of Foreign Bondholders
Description: This paper analyzes the Corporation of Foreign Bondholders (CFB), an association of British investors holding bonds issued by foreign governments. The CFB played a key role during the heyday of international bond finance, 1870-1913, and in the aftermath of the defaults of the 1930s. It fostered coordination among creditors, especially in cases of default, arranging successfully for many important debt restructurings, though failing persistently in a few cases. While a revamped creditor association might once again help facilitate creditor coordination, the relative appeal of defection over coordination is greater today than it was in the past. The CFB may have had an easier time than any comparable body would have today.

Network Externalities and Dollarization Hysteresis: The Case of Russia
Description: Dollarization in Russia increased rapidly during the early 1990s, but failed to come down in the second half of the 1990s in spite of exchange rate stabilization. To explain this "dollarization hysteresis," this paper develops a model in which network externalities in the demand for currency can generate multiple stable steady states for the dollarization ratio. The model is estimated using a new source of data on dollar currency holdings in Russia. On the basis of these estimates, which confirm the existence of network externalities, the paper discusses several policies that could result in a permanent decrease in dollarization.
