This paper develops a structural general equilibrium model to analyse the reactions of the nominal exchange rate and the domestic price level to three types of external shock in emerging economies that have limited access to world capital markets. Although the results depend crucially on the type of external shock, each of the two national balance-sheet parameters considered here -the risk premium and the ratio of external indebtedness-exacerbates the reactions of the two endogenous variables without altering the degree of exchange-rate pass-through (erpt). Moreover, flatter Phillips curves, as observed today in many economies, tend to increase erpt. On the basis of these results, the authorities of emerging economies seeking to stabilize markets and limit erpt are advised to minimize the two risk parameters by applying a flexible inflation-targeting regime.

EXCHANGE-RATE VARIATIONS AND THE RATE OF INFLATION IN EMERGING ECONOMIES • JOSÉ GARCÍA-SOLANES AND FERNANDO TORREJÓN-FLORESThe literature on variations in exchange rates and prices in open economies has typically focused on exchangerate pass-through (erpt), that is, the extent to which exchange-rate fluctuations are transmitted to domestic prices. In order to assess the pure erpt effects the analysis should be restricted to the initial impacts on import prices or, at most, to the first stages affecting domestic producer prices. If the analysis is extended to capture the short-run clearing of assets and goods markets, the final ratio of domestic price variations to exchange-rate variations gives a more indirect measure of erpt. The relationships between exchange rates and domestic prices are sensitive to the type of external shocks that trigger adjustments, as emphasized by Mishkin (2008).Although it is generally held that low inflation rates, monetary policy credibility, and exchange-rate flexibility contribute to lower erpt, 1 some authors have obtained estimates that contradict or call into question that consensus. For example, Nogueira (2007) found that the adoption of an inflation-targeting regime -thus strengthening monetary policy credibility-increased erpt in the Czech Republic and the Republic of Korea; and Coricelli, Jazbec and Masten (2004) discovered that exchange-rate flexibility magnified the erpt coefficient in four advanced transition economies. In a similar vein, Byrne, Chavali and Kontonikas (2010), Sek and Kapsalyamova (2008), and Korhonen and Wachtel (2006) found that erpt effects are, in fact, very heterogeneous and asymmetrical among countries. According to Mishkin (2008), those divergent findings may be explained by the fact that authors did not take into account the type of external shocks that hit the economies.In this paper, we examine the erpt that occurs when exchange rates and domestic prices are adjusted in the short-run macroequilibrium. In order to address the (2006), Sek andKapsalyamova (2008), andTakatoshi a...
