A simple test of momentum in foreign exchange markets

This study proposes a new method for testing for the presence of momentum in nominal exchange rates, using a probabilistic approach. We illustrate our methodology estimating a binary response model using information on local currency / US dollar exchange rates of eight emerging economies. After controlling for important variables a§ecting the behavior of exchange rates in the short-run, we show evidence of exchange rate inertia; in other words, we Önd that exchange rate momentum is a common feature in this group of emerging economies, and thus foreign exchange traders participating in these markets are able to make excess returns by following technical analysis strategies. We Önd that the presence of momentum is asymmetric, being stronger in moments of currency depreciation than of appreciation. This behavior may be associated with central bank intervention

El crecimiento económico de corea del sur y sus posibilidades de alterar el equilibrio en Asia-Pacífico

El interés de esta monografía es analizar el crecimiento económico de Corea del Sur y sus posibilidades de alterar el equilibrio en la región de Asia-Pacífico. A partir de los conceptos de poder duro y equilibrio de poder propuestos por Joseph Nye y Ernst Haas, se examinan los principales hitos del proceso de desarrollo nacional y se determina en qué sentido el incremento del poder duro nacional le permite a este país posicionarse como una potencia regional en ascenso. Así mismo, se evalúan los procesos de liderazgo regional de China y Japón que impiden a Corea del Sur alterar sustancialmente el equilibrio de poder en esta región del mundo.

Modelling official and parallel exchange rates in Colombia under alternative regimes: a non-linear approach

We examine the long-run relationship between the parallel and the official exchange rate in Colombia over two regimes; a crawling peg period and a more flexible crawling band one. The short-run adjustment process of the parallel rate is examined both in a linear and a nonlinear context. We find that the change from the crawling peg to the crawling band regime did not affect the long-run relationship between the official and parallel exchange rates, but altered the short-run dynamics. Non-linear adjustment seems appropriate for the first period, mainly due to strict foreign controls that cause distortions in the transition back to equilibrium once disequilibrium occurs
