Nonlinear, Nonparametric, Nonessential Exchange Rate Estimation

Abstract: A wide variety of empirical exchange rate mo.dels have been estimated over the years. But, despite the considerable energies that have been devoted to this work, the economics profession has remarkably little to show for itself. There is little evidence that conclusively links the bilateral exchange rates of typical OECD countries to "fundamental" macroeconomic determinants of exchange rates, such as money, output, relative prices, or interest differentials. Coefficient estimates are notoriously unstable and frequently " mis-signed" (compared with theoretical predictions); exchange rate equations do not fit particularly well, and forecast no better than the simplest naive alternatives. Recently, a new class of exchange rate models was introduced by Paul Krugman (1988). These models provide a potential reason for the poor performance of traditional exchange rate models, because they are nonlinear. If the exchange rate actually depends in a nonlinear way on exogenous macroeconomic fundamentals, linear exchange rate models may work poorly, even though the exchange rate is closely linked to fundamentals. In this paper we provide a brief sketch of some of this work, as well as some preliminary evidence on the actual performance of these nonlinear models. In our empirical analysis, we use a nonparametric estimator that can handle a wide variety of nonlinear phenomena. We examine fixed exchange rate regimes, where nonlinearities should be quite easy to detect. However, we do not find strong empirical support for the hypothesis that the incorporation of nonlinear effects significantly improves models of exchange rate determination. In Section I, we briefly review the theoretical literature on nonlinear "target zone" exchange rate models, linking this work to the tests for "intrinsic" bubbles (we draw heavily on recent papers by Kenneth Froot and Maurice Obstfeld, 1989a,b). Our methodology and data are discussed in Section II; Section III contains new empirical tests for nonlinearities in exchange rate models.

The political economy of capital controls

Abstract: This paper studies the institutional and political determinants of capital controls in a sample of 20 OECD countries for the period 1950-1989. One of the most interesting results is that capital controls are more likely too be imposed by strong governments which have a relatively "free" hand over monetary policy, because the Central Bank is not very independent. By imposing capital controls, the governments raise more seigniorage revenue and keep interest rates artificially low. As a result, public debt accumulates at a slower rate than otherwise. This suggests that an institutional reform which makes the Central Bank more independent makes it more difficult for the government to finance its budget. The tightening of the fiscal constraint may force the government to adjust towards a more sound fiscal policy. We also found that, as expected and in accordance with the theory, capital controls are more likely to be introduced when the exchange rate is pegged or managed. On the contrary, we found no effects of capital controls on growth: we reject rather strongly the hypothesis that capital controls reduce growth.

Controlling Currency Mismatches in Emerging Markets

Abstract: In most of the currency crises of the 1990s, the largest output falls have occurred in those emerging economies with large currency mismatches, a phenomenon that occurs when assets and liabilities are denominated in different currencies such that net worth is sensitive to changes in the exchange rate. Currency mismatching makes crisis management much more difficult since it constrains the willingness of the monetary authority to reduce interest rates in a recession (for fear of initiating a large fall in the currency that would bring with it large-scale insolvencies). The mismatching also produces a "fear of floating" on the part of emerging economies, sometimes inducing them to make currency-regime choices that are not in their own long-term interest.
