Pass-through in dollarized countries: should Ecuador abandon the US dollar?

In this article, we examine the convenience of dollarization for Ecuador today. As Ecuador is strongly integrated financially and commercially with the United States, the exchange rate pass-through should be zero. However, we sustain that rising rates of imports from trade partners other than the United States and subsequent real effective exchange rate depreciations are causing the pass-through to move away from zero. Here, in the framework of the Vector Error Correction Model, we analyse the impulse response function and variance decomposition of the inflation variable. We show that the developing economy of Ecuador is importing inflation from its main trading partners, most of them emerging countries with appreciated currencies. We argue that if Ecuador recovered both its monetary and exchange rate instruments, it would be able to fight against inflation. We believe such an analysis could be extended to other countries with pegged exchange rate regimes.     

Monetary policy credibility and exchange rate pass-through: Some evidence from emerging countries

Considering external constraints on monetary policy in emerging countries, we propose a semi-structural vector autoregressive model with exogenous variables (VARX) to examine the exchange rate pass-through to domestic prices. We demonstrate that a lower exchange rate pass-through is associated with a credible monetary policy aiming at controlling inflation. The empirical results suggest that the exchange rate pass-through is higher in Latin American countries than in East Asian countries. The exchange rate pass-through has declined after the adoption of an inflation targeting monetary policy.     

Do domestic bond markets participation help reduce financial dollarization in developing countries?

In this paper, I analyze the effect of domestic sovereign bond market (BM) participation on financial dollarization using a large panel of 114 developing countries over the period 1984–2009. Building on entropy balancing, my results reveal strong evidence that domestic BM participation significantly reduces financial dollarization in domestic BM countries compared to their non-domestic BM peers. Moreover, I find that the favorable impact of domestic BM on financial dollarization (i) is larger for inflation targeting countries compared to non-inflation targeting countries, (ii) is apparent exclusively in a non-pegged exchange rate regime, (iii) and is larger when there are fiscal rules that constrain the discretion of fiscal policy makers. Finally, I show that the induced drop in inflation rate and its variability, nominal exchange rate variability, and seigniorage revenue are potential transmission mechanisms through which the presence of domestic BM reduces financial dollarization in domestic BM countries.     

Exchange-rate pass-through at the product level

Abstract.  We use a detailed database to investigate exchange-rate pass-through at the product level for a large number of countries. The empirical analysis suggests that pricing behaviours are dichotomous, with complete pass-through in around 25% of sectors and significant pricing-to-market in the remaining ones. Average long-run pass-through coefficient is close to 80%; this result hides a strong heterogeneity of pass-through behaviours across sectors. Even when composition effects are controlled for, average pass-through varies across importing countries. The econometric analysis shows that pass-through tends to be higher in volatile environments; in less developed countries; in weakly integrated markets.     

Modelling real exchange rate effects on output performance in Latin America

This article empirically analyses real per capita GDP growth for six Latin American countries (Argentina, Brazil, Chile, Columbia, Mexico, Venezuela) in terms of real exchange rate depreciations, inflation and US interest rates, focussing on the role of the real exchange rate. We find evidence of nonlinearity in this relationship, which we capture through a smooth transition regression model. With the exception of Mexico, nonlinearity in economic growth is associated with changes in the real exchange rate, with depreciations leading to different relationships compared with appreciations. Regimes for Mexico are associated with the past growth rates, with effectively symmetric effects of real exchange rate changes. Although our results are in accord with other recent literature in that depreciations may have negative effects for growth, the asymmetries we uncover indicate that these effects depend on the conditioning state.     

A model of liability dollarization and myopic governments

Abstract

Liability dollarization of the domestic banking system represents a source of vulnerability for emerging market countries. The root cause is a lack of faith in the domestic currency, which ultimately stems from the belief that the government will not follow policies that promote long-run currency stability. This paper presents a model in which government myopia determines the unofficial dollarization of bank credit. Specifically, myopic politicians will choose low interest rates to expand short-run output in order to get re-elected, but this choice has the long-run consequence of increasing dollar lending. Increased liability dollarization is shown to force the hand of future decision-makers into choosing fixed exchange rates because of the fear that large depreciations will destroy balance sheets. The results imply that institutional reforms are necessary to reverse liability dollarization.     

Differences in long run exchange rate pass-through into import prices in developing countries: An empirical investigation

This paper investigates the exchange rate pass-through into import prices in a sample of 24 developing countries over the period from 1980 to 2003. We estimate a pass-through equation determined by a combination of the nominal exchange rate, the price of the competing products, the exporter's costs and demand conditions. We adopt non-stationary panel estimation techniques and tests for cointegration. In the long run, homogeneity of pass-through rates across countries can be rejected. Moreover, we show that most of these differences in exchange rate pass-through into import prices are due to three macroeconomics determinants: exchange rate regimes, trade barriers and inflation regimes.     

Devaluation and pass-through in indebted and risky economies

This paper develops a structural general equilibrium model to analyse the pass-through from devaluation to producer and consumer prices in Emerging Market Economies (EMEs). Simulation analysis shows that balance-sheet effects created by capital market imperfections and the home bias shrink the impact of devaluation on both types of internal prices. This finding helps explain why pass-through to internal prices is low in EMEs. It also shows that, for benchmark values of the parameters, devaluation remains a good device to modify the real exchange rate and to mitigate the negative impact of external shocks in EMEs.     

Currency crises and foreign credit in emerging markets: Credit crunch or demand effect?

Currency crises of the past decade highlighted the importance of balance-sheet effects of large devaluations. Currency crisis literature identified a decline in credit as one of the channels through which such crises affect real economic activity. We find empirical evidence of the existence of this channel and quantify its extent and persistence: controlling for a host of fundamentals, we find a decline in foreign credit to emerging market private firms of about 25 percent in the first year following large depreciations. This decline is especially large in the first five months, is less pronounced in the second year, and disappears entirely by the third year. We show that only about a quarter of the initial decline in credit could be attributed to the “credit crunch,” while the rest of the decline is due to contracting demand. After six months, however, most of the credit decline could be attributed to supply effects.     

Differences in exchange rate pass-through in the euro area

This paper focuses on the pass-through of exchange rate changes into the prices of imports made by euro area countries originating outside the area. Using data on import unit values for 13 different product categories for each country, we estimate industry-specific rates of pass-through across and within countries for all euro members. In the short-run, pass-through rates differ across industries and countries and are less than one. In the long-run neither full pass-through nor equality of pass-through rates across industries and countries can be rejected. Differences exist across euro area countries in the degree that a common exchange rate movement gets transmitted into consumer prices and costs of production indices. Most of these differences in transmission rates are due to the distinct degree of openness of each country to non-euro area imports rather than to the heterogeneity in the structure of imports.     

Exchange rate pass through,macro fundamentals and regime choice in Latin America

The impact of changes in exchange rate on inflation is an issue of extreme importance for nations with a history of high inflation. While there have been significant studies on industrial and advanced economies, little analysis has been conducted on smaller economies that are open to trade and financial relationships. This paper estimates exchange rate pass-through (ERPT) into CPI and import prices from 1970 to 2010 for nine Latin American nations. ERPT is further estimated for each decade documenting declining pass-through after the turn of the millennium. The paper also examines the impact of macro fundamentals on ERPT, and finds monetary policy stability, inflation rate and trade openness to have a positive impact on pass-through. Finally, de facto exchange rate flexibility indices are constructed and ERPT rates are found to negatively affect them.     

The changing nature of the real exchange rate: The role of central bank preferences

We investigate the sources of real exchange rate fluctuations. We do so, first, in the context of a DSGE model that explicitly considers the central bank's preferences. Then we estimate SVAR models, where shocks are identified by sign restrictions derived from the DSGE model. We perform this exercise for twelve countries, nine of which have adopted inflation targeting during the period analyzed. In sharp contrast to the previous evidence in the literature, we find that exchange rate (country risk premium) shocks have become the main drivers of real exchange rate dynamics, while real shocks play a less important role. Evidence from the DSGE model reveals that, as the central bank becomes more averse to inflation movements, and cares less about nominal exchange rate fluctuations, the impact of nominal shocks on the real exchange rate tends to increase, while the impact of real shocks decreases. Our results suggest that the adoption of inflation targeting, along with a floating exchange rate, contributes to a shift in the relative importance of demand and country risk premium shocks in determining the RER.     

A stable demand for money despite financial crisis: the case of Venezuela

The demand for broad money in Venezuela is investigated over a period of financial crisis and substantial exchange rate fluctuations. The analysis shows that there exist a long-run relationship between real money, real income, inflation, the exchange rate and an interest rate differential, that remains stable over major policy changes and large shocks. The long-run properties emphasize that both inflation and exchange rate depreciations have negative effects on real money demand, whereas a higher interest rate differential has positive effects. The long-run relationship is finally embedded in a dynamic equilibrium correction model with constant parameters. These results have implications for a policy-maker. In particular, they emphasize that with a high degree of currency substitution in Venezuela, monetary aggregates will be very sensitive to changes in the economic environment.     

Exchange rate pass-through and inflation targeting in Peru

It has been widely documented that the exchange rate pass-through to domestic inflation has decreased significantly in most of the industrialized world. As microeconomic factors cannot completely explain such a widespread phenomenon, a macroeconomic explanation linked to the inflationary environment—that a low and more stable inflation rate leads to a decrease in the pass-through—has gained popularity. Using a structural VAR framework, this paper presents evidence of a similar decline in the pass-through in Peru, a small open economy that gradually reduced inflation to international levels in order to adopt a fully fledged inflation targeting scheme in 2002. It is argued that the establishment of a credible regime of low inflation has been instrumental in driving the exchange rate pass-through down.     

Dollarization and financial integration

How does a country's exchange rate regime impact its ability to borrow from abroad? We build a small open economy model in which the government responds to shocks by adjusting monetary policy and foreign borrowing. Sovereign borrowing is subject to endogenous limits, which ensure repayment when the default punishment corresponds to financial autarky. Dollarizing implies renouncing monetary policy, but can make access to international debt markets more valuable, thereby loosening borrowing constraints. This mechanism linking dollarization to financial integration is consistent with observed declines in spreads on foreign-currency debt in countries adopting the dollar or the euro.     

Exchange rate pass-through in deflation: The case of Taiwan

This paper incorporates deflation in an analysis of the relationship between the exchange rate pass-through and inflation. Using a nonlinear model based on monthly data of Taiwan's import prices from 1981 to 2008, we find that the degree of exchange rate pass-through is increasing in deflation. The increase becomes smaller when the price of oil is excluded. Evidence for pass-through increasing in deflation has not previously been found in the existing literature and presents a new understanding of the pricing behavior of firms. Poor profits in deflation cause firms to pass through most of the cost of exchange rate changes to their products to avoid exiting the market.     

Fighting inflation in Mexico: Theory and evidence

Mexico adopted the inflation targeting strategy in 2002, and this came together with declining inflation. According to the economic authorities, this also brought about lower pass-through of exchange rate changes into inflation. The objective of this article is to test the main hypotheses of Mexico’s prize-stabilization strategy. As a preliminary step, we show evidence whereby the interest rate has not the impact on demand assumed in the conventional view. We then estimate econometric models, which show first of all that inflation depends essentially on the evolution of labor and input costs. Then we demonstrate that higher employment and higher wages associated with higher output do not necessarily entail higher labor costs because productivity also increases when output rises. In the final section, we set forth our main conclusions, which cast doubts on some crucial aspects of the inflation targeting strategy, and propose a different interpretation about why inflation declined in this country.

Asymmetry Effects of Exchange Rate Changes on Domestic Production: Evidence from Nonlinear ARDL Approach

Currency depreciation is said to have positive or negative effects on domestic production. Previous studies that tried to address this issue using Australian data have been inconclusive at best but mostly showed no effects. One common feature of all studies is that they have assumed that the effects of exchange rate changes are symmetric. In this paper, we use the concept of partial sum and separate appreciations from depreciations to test whether the effects are symmetric or asymmetric. Application of the nonlinear ARDL approach of Shin et al. (2014) reveals that indeed the effects of changes in the real effective exchange rate of the Australian dollar are asymmetric in the short run as well as in the long run. While in the short run both appreciations and depreciations affect Australian domestic production, only effects of appreciation last into the long run, a unique finding.     

LINKAGES BETWEEN EXCHANGE RATE POLICY AND MACROECONOMIC PERFORMANCE

Using a sample of 104 countries, we study macroeconomic performance from 1973 to 2007. We examine GDP growth, inflation rate, growth volatility and inflation volatility, and their response to a ‘words versus deeds’ measure of exchange‐rate policy, which is obtained by interacting a country's de jure and its de facto policy. For non‐industrialized countries, the highest growth rates and the lowest inflation volatility are associated with countries that pursue fear of floating policy, whereas countries that pursue a matched float policy (de jure and de facto floating) have the highest inflation rates but the lowest GDP volatility.
