Greed, impatience and exchange rate determination

This paper offers a theoretical explanation for the determination of exchange rates under specific conditions which can/could be found in some OECD and newly industrialised countries. In an Obstfeld (1994) framework extended to incorporate
government expropriation reneging on a fixed exchange rate promise
unambiguously produces short term benefits, but long term losses. The choice of exchange rate regime depends on the combined effect of greediness (expropriation) and impatience (political instability), though not straightforwardly. In particular, similarly stable countries may choose different exchange rate regimes
due to different levels of rent-seeking, for instance Mexico and Chile in the 1980s.
