On Dollarization
(1999-04-20) Calvo, Guillermo A.
Recent worldwide turmoil in financial markets is triggering a major revision of the conventional wisdom about Emerging Market countries’ (EMs) macroeconomic management. As a result, the debate is wide open as to the set of policies and institutional arrangements that would ensure EMs’ macroeconomic stability. Opinions range from those favoring further pursuing market-friendly reforms to controls on capital mobility and even trade, and from dollarization to floating exchange rates. The debate on the appropriate exchange rate system, in particular, has taken center-stage.
Rational Contagion and the Globalization of Securities Markets
(Elsevier, 2000-06) Calvo, Guillermo A.; Mendoza, Enrique G.
This paper argues that globalization may promote contagion by weakening incentives for gathering costly information and by strengthening incentives for imitating arbitrary market portfolios. In the presence of short-selling constraints, the gain of gathering information at a fixed cost may diminish as markets grow. Moreover, if a portfolio manager’s marginal cost for yielding below-market returns exceeds the marginal gain for above-market returns, there is a range of optimal portfolios in which all investors imitate arbitrary market portfolios and this range widens as the market grows. Numerical simulations suggest that these frictions can have significant implications for capital flows in emerging markets.
