The dilemma of exchange rate arrangements in East Asia

This paper analyzes exchange rate flexibility in East Asia and explores what has changed since the Asian financial crisis. Our focus is not on the choice of an appropriate exchange rate regime in East Asia, but rather on exchange rate flexibility and management in the region. We find that exchange rate management in East Asia differs based on the country and the time period. We identify major concerns about current exchange rate arrangements in East Asia, including asymmetric responses to external shocks, competitive devaluation, and the dilemma of choosing between asset dollarization and liability dollarization. The paper concludes with some policy implications for an exchange rate arrangement in East Asia.     

完全美元化及利弊评析

完全美元化是指完全放弃本币，使用外币(美元)作为记账单位、支付手段或价值储藏，具有无限法偿能力，其实质是完全而不可逆转的固定汇率制度。评析了完全美元化的利与弊，指出完全美元化是一把“双刃剑”，其无论对于美元化国家还是对于美国都会带来一定的经济利益，但同时也会造成一定的损失。     

Financial dollarization: Short-run determinants in transition economies

This paper examines the determinants of financial dollarization in transition economies from a short-run perspective. Using aggregate monthly data of deposit and loan dollarization we study the drivers of short-term fluctuations in dollarization and test their importance at different levels of dollarization. The results provide evidence that (a) the positive (negative) short-run effects of depreciation (monetary expansion) on deposit dollarization are exacerbated in high-dollarization countries; (b) short-run loan dollarization is mainly driven by banks matching of domestic loans and deposits, currency matching of assets and liabilities, international financial integration, and institutional quality; and (c) both types of short-run dollarization are affected by interest rate differentials and deviations from desired dollarization.     

The Impact of Deposit Dollarization on Financial Deepening

Banks in highly dollarized economies face risks that significantly affect their ability to perform their financial intermediation role. In these economies, dollarization plays a dual role: on the one hand, it provides a hedging instrument protecting the value of savings; on the other hand, it generates a currency mismatch on banks' balance sheets and increases default risk. Through these effects deposit dollarization can affect credit extension. This paper investigates the role of deposit dollarization on the financial depth of forty-four emerging market economies. Findings suggest that deposit dollarization has a consistent and negative impact on financial deepening, except in high-inflation economies.     

Money, Monetary Policy, and Central Banking

Anna Schwartz's insights and careful analysis of the forces shaping institutions have contributed greatly to our understanding of money, central banks, and monetary policy. We discuss these contributions in the context of three issues. The first concerns governments' role in money. First, we focus on Anna's contribution to our understanding of the quality of money. In this context, we consider how the acceleration of globalization and developments in information technology has, as an external development, forced improvements in institutions and social arrangements. The second issue concerns the potential for currency boards to serve as an intermediate institution in the evolution toward and, perhaps now, away from so many central banks and sovereign monetary authorities. Finally, we turn our attention to current issues in the implementation of monetary policy.     

Financial dollarization in Russia: causes and consequences

We review some aspects of financial dollarization in Russia, applying the main relevant theories to analyse the dynamics of several dollarization indicators. An econometric model of the short-run dynamics of deposit and loan dollarization is estimated for the last decade. We find that ruble appreciation was the main driver of the de-dollarization that occurred then and of the later episode of renewed dollarization. We estimate the overall (and sectoral) currency mismatches of the Russian economy. Evidence is presented for the significant currency risk vulnerability of the non-banking private sector.     

Time Inconsistency and Free‐Riding in a Monetary Union

In monetary unions, a time inconsistency problem in monetary policy leads to a novel type of free‐rider problem in the setting of non‐monetary policies. The free‐rider problem leads union members to pursue lax non‐monetary policies that induce the monetary authority to generate high inflation. Free‐riding can be mitigated by imposing constraints on non‐monetary policies. Without a time inconsistency problem, the union has no free‐rider problem; then constraints on non‐monetary policies are unnecessary and possibly harmful. This theory is here detailed and applied to several non‐monetary policies: labor market policy, fiscal policy, and bank regulation.     

Dollarization,Seigniorage, and Prices: The Case of North Korea

This study employs a general equilibrium monetary search model to examine the effects of the recent dollarization in North Korea on seigniorage and prices. Maximum seigniorage is generated at a high rate of money growth when dollarization is mild. However, under a high degree of dollarization seigniorage declines sharply when the money growth rate is high. Accordingly, seigniorage can be increased by de-dollarizing the economy through lowering the money growth rate. This finding implies that the post-2013 price stabilization may be a result of the restriction on printing of money with the aim of increasing seigniorage. This finding also recognizes that the North Korean authorities have little room for maneuver on monetary policy under the conditions of widespread dollarization.     

Does Inflation Targeting Help Reduce Financial Dollarization?

We examine whether adopting an inflation‐targeting regime helps reduce financial dollarization as predicted by Ize and Levy Yeyati's ( 2003 ) portfolio model. To address the self‐selection problem of policy adoption, we apply a variety of propensity score matching methods to a large sample of 106 developing countries for the years 1985–2004. We find strong evidence that inflation targeting has large and significant treatment effects on lowering both actual financial dollarization and the model implied minimum variance portfolio dollarization. Our results are robust to alternative samples and model specifications and also to control for additional factors in postmatching regressions.
