International Economic Interdependence and Exchange‐rate Adjustment under Persistent Stagnation

Using a two‐country, two‐commodity dynamic optimization model with general homothetic preference for the commodities, this paper examines the effects of a tariff and a quota on consumption and employment in the case where persistent unemployment arises due to a liquidity trap. A trade restriction improves the current account, which causes the home currency to appreciate and harms the competitiveness of home firms. Therefore, home employment and consumption decrease while foreign employment and consumption increase. Tariff‐quota equivalence is found to be valid. Preference, technological and policy parameter changes that improve the current account in general worsen home unemployment.     

Policy Measures to Alleviate Foreign Currency Liquidity Shortages under Aggregate Risk with Moral Hazard

During the recent global financial crisis, certain central banks introduced two innovative cross‐border operations to deal with the problems of foreign currency liquidity shortages: domestic liquidity operations using cross‐border collateral and operations that supply foreign currency among central banks based on standing swap lines. We show theoretically that central banks improve the efficiency of equilibrium under foreign currency liquidity shortages using these two innovative temporary policy measures.     

Tariffs,Offshoring and Unemployment in A Two‐Country Model

This paper develops a two‐country model that incorporates offshoring opportunities, and analyses the effects of tariffs under economic stagnation in a liquidity trap that causes unemployment. We find that a rise in tariffs on imports of outsourced goods contributes to an increase in employment by inducing a shift in production, but also leads to an appreciation of the real exchange rate that tends to reduce employment. The effect of real exchange rate appreciation dominates the effect of the production shift, and accordingly employment and consumption fall. The effects of tariff adjustments are reversed, however, when there is no liquidity trap and hence no unemployment.     

OPTIMAL EXPORT AND HEDGING DECISIONS WHEN FORWARD MARKETS ARE INCOMPLETE

This paper examines the behaviour of the competitive firm that exports to two foreign countries under multiple sources of exchange rate uncertainty. There is a forward market between the home currency and one foreign country's currency, but there are no hedging instruments directly related to the other foreign country's currency. We show that the separation theorem holds when the firm optimally exports to the foreign country with the currency forward market. The full‐hedging theorem holds either when the firm exports exclusively to the foreign country with the currency forward market or when the relevant spot exchange rates are independent. In the case that the relevant spot exchange rates are positively (negatively) correlated in the sense of regression dependence, the firm optimally opts for a short (long) forward position for cross‐hedging purposes.     

Endogenous inflows of speculative capital and the optimal currency appreciation path

Abstract This paper examines the optimal appreciation path of an undervalued currency in the presence of speculative capital inflows that are endogenously affected by the appreciation path. A central bank decides its appreciation policy based on three costs: (i) misalignment costs associated with the gap between the actual and long‐run equilibrium exchange rates, (ii) short‐term adjustment costs due to resource reallocation, and (iii) capital losses due to speculative capital inflows. Our model finds (1) when speculators face no liquidity shocks, the central bank tends to appreciate the currency quickly to discourage speculative capital; (2) when speculators face liquidity shocks, the central bank optimally pre‐commits to a slower appreciation path, and the appreciation takes the longest time when the probability of liquidity shocks takes intermediate values; (3) the central bank tends to appreciate the currency more quickly when it conducts discretionary policy.     

A simple aggregate demand analysis with dynamic optimization in a small open economy

We develop a very simple aggregate demand analysis of a small open economy that suffers from secular demand stagnation. It looks like the conventional Keynesian cross analysis but considers dynamically optimizing behavior of households and firms, international capital movement, and the current account adjustment. We find that parameter changes that improve the current account yield an appreciation pressure on the home currency and decrease demand for the home commodity and labor. Consequently, they worsen deflation and decrease consumption and income. This result is quite opposite to that under full employment. For example, an exogenous rise in the price of the home commodity decreases employment, consumption and income. If a country owns greater foreign assets, it suffers from less employment, consumption and income.     

MODELLING THE TRANSITION TOWARDS THE RENMINBI'S FULL CONVERTIBILITY: IMPLICATIONS FOR CHINA'S GROWTH

There is a widespread consensus that China needs to rebalance its export‐driven growth paradigm towards a more consumption‐based one and that such process is to be accompanied by the transition towards the renminbi's full convertibility. However, the Chinese authorities have so far acted with great caution because this transition cannot but accelerate the slowdown of China's growth which will likely occur because of other structural factors. We address these issues by means of a two‐country two‐stage (before and after the renminbi's full convertibility) model, which reproduces some qualitative features of China's growth pattern and its relationship with the United States. We analyse the extent to which altering the Chinese exchange rate regime, as well as other policies affecting sensitive social and economic issues, may impact on the short‐, medium‐ and long‐term evolution of the Chinese economy. The paper shows that by lifting the controls on the capital account and letting the currency float, the Chinese authorities will renounce those policy instruments for controlling the allocation of the national resources and the dynamics of China's economy.     

Global Production and Currency Devaluation*

We model the production allocation choices of a multinational enterprise (MNE) in a three‐country framework—one northern country and two southern ones. Products made in the South are of lower quality than those made in the North. Substitutability between goods differs due to variations in product quality. We investigate how exchange rates affect production, employment, and welfare, and find that currency devaluation from different countries brings contrasting results. In particular, an appreciation in the southern country (X) producing the lowest‐quality good with the least cost may reduce production (employment) in the North, while an appreciation in the other southern currency (Y) always does the opposite. A northern depreciation against both southern currencies may increase production in country X, but always reduces that in country Y. These arise because the MNE shifts production globally to minimize costs. Northern welfare always falls following currency appreciation in southern countries.     

Credit in Times of Stress: Lessons from Latin America during the Global Financial Crisis

The 2008–2009 global financial crisis disrupted the provision of credit in Latin America less than in previous crises. This paper tests whether specific characteristics at both the bank and country levels at the onset of the global crisis contributed to the behavior of real credit growth in this region during the crisis. As shown, financial soundness characteristics of Latin American banks, such as capitalization, liquidity, and bank efficiency in the pre‐crisis period, played a role in explaining the dynamics of real credit during the crisis. We also found that foreign banks and banks that had expanded credit growth more before the crisis were also those that cut credit the most. Among country‐specific characteristics, we found evidence that balance sheet measures such as the economy's overall currency mismatches and external debt ratios (measuring either total debt or short‐term debt) were key variables in explaining credit growth resilience.     

TARIFF JUMPING FOREIGN DIRECT INVESTMENT DECISION IN A QUALITY‐DIFFERENTIATED MARKET

Using a product differentiation model, this paper discusses the issue of transnational firms evading tariffs and investing directly in a host country (through foreign direct investment (FDI)). Where product quality is differentiated between foreign and host country firms and assuming a firm's quality requirement is a long‐term strategy and is not affected by a foreign firm's trade decision, we obtain the following findings. First, whether or not a host country firm produces high or low quality products, raising the quality requirement for foreign products will increase the possibility of a foreign firm choosing FDI instead of exporting a product to the host country. Second, raising the quality requirement for domestic products will lower the possibility of foreign firms choosing FDI without regard to the product's quality. Finally, given a competitor in the host country, in FDI, a foreign high‐quality product‐producing firm has an advantage over a low‐quality product‐producing firm. We also find that even when firms' quality decisions are affected by a foreign firm's trade decision, most of the above results will still hold.     

Understanding Benign Liquidity Traps: The Case of Japan

Japan has been in a benign liquidity trap since the 1990s. In a benign liquidity trap, interest rates approach zero and monetary policy is ineffective but output and employment perform decently. Such a pattern contradicts traditional macro theories. This paper introduces a monetary general equilibrium model that is compatible with Japan's performance and resolves puzzles associated with liquidity traps. Possible conclusions for Anglo‐Saxon countries and eurozone members are also discussed.     

CROSS‐HEDGING OF EXCHANGE RATE RISKS: A NOTE*

This note studies the optimal production and hedging decisions of a competitive international firm that exports to two foreign countries. The firm faces multiple sources of exchange rate uncertainty. Cross‐hedging is plausible in that one of the two foreign countries has a currency forward market. We show that the firm's optimal forward position is an over‐hedge, a full‐hedge or an under‐hedge, depending on whether the two random exchange rates are strongly positively correlated, uncorrelated or negatively correlated, respectively.     

ENDOGENOUS FLUCTUATIONS IN TWO‐COUNTRY MODELS*

This paper investigates the interlinkage in the business cycles of large‐country economies in a free‐trade equilibrium. We consider a two‐country, two‐good, two‐factor general equilibrium model with Cobb‐Douglas technologies and linear preferences. We also assume decreasing returns to scale in the consumption good sector. We first identify the determinants of each country's global accumulation pattern in autarky equilibrium, and secondly we show how a country's business cycles may spread throughout the world once trade opens. We thus give capital intensity conditions for local and global stability of competitive equilibrium paths.     

Gender differences in self‐employment

This paper examines the factors that influence transitions into self‐employment, paying particular attention to gender differences. We find that: (i) men are more responsive to the wage differential between wage/salaried employment and self‐employment; (ii) liquidity constraints are more important for men; and (iii) the link between father's self‐employment status and the probability of self‐employment is stronger for men. Taken together, these results suggest that, for women, self‐employment is a closer substitute for part‐time work and labour‐market inactivity than it is for men. We attribute such differences to the different labour market opportunities and occupational strategies of women.     

Strategic competition and optimal parallel import policy

Abstract In a two‐country Hotelling type duopoly model of price competition, we show that parallel import (PI) policy can act as an instrument of strategic trade policy. The home firm’s profit is higher when it cannot price discriminate internationally if and only if the foreign market is sufficiently bigger than the domestic one. The key mechanism in the model is that the home firm’s incentive to keep its domestic price close to the optimal monopoly price affects its behavior during price competition abroad. We also analyze the welfare implications of PI policies and show that our key insights extend to quantity competition.     

Bi‐currency versus Single‐currency Targeting: Lessons from the Russian Experience

This paper examines how the 2005 shift in Russian exchange rate policy from US dollar (USD) single‐currency to USD–EUR (euro) bi‐currency targeting has impacted domestic interest rates. The finding show that this policy shift has disconnected Russian interest rates from US dollar‐denominated interest rates, while instead linking them to a synthetic interest rate composed of USD and EUR rates at the same proportion as that of these two currencies in the currency basket against which the ruble's exchange rate is set. The Russian experience shows that while the adoption of bi‐currency targeting may help ensure that domestic interest rates are less dependent on the monetary cycle of a single country, these rates are instead likely to reflect financial developments in all countries whose currencies are included in the currency basket. This insight is likely to be relevant for other countries that pursue basket‐targeting policies.     

SECTORAL EXCHANGE RATE PASS-THROUGH: TESTING THE IMPACT OF POLICY REFORMS IN INDIA

This paper analyses the impact of India's policy reforms on exchange rate pass‐through into import and export prices, using panel data (at one‐digit SITC level) for pre‐ (1980–90) and post‐reform (1991–2001) periods. While the pass‐through into import prices has declined, the pass‐through into export prices (in USD terms) has increased during the 1990s. The results suggest that, relative to rupee depreciation, Indian exporters increased their USD prices around 20% in the 1980s, but decreased them by around 70% in the 1990s. Moreover, the number of sectors exhibiting some degree of pass‐through increased in the 1990s (six), relative to the 1980s (three). These changes may be attributable to the elimination of currency and trade controls, which increased competition among firms and fostered a concern with market share gains in the 1990s over an attempt to use depreciations to increase profits in the 1980s.     

COMPETITION, PARALLEL IMPORTS AND COST-REDUCING INNOVATION

Incorporating parallel imports (PI), we develop a two‐country two‐firm model which relates to the incentives for cost‐reducing innovation. We show that PI may facilitate or inhibit the manufacturers' incentives to innovate. In particular, PI could encourage both firms' innovations. The difference between the manufacturer's profits under successful innovation and failed innovation is either a U‐shaped curve or an inverted U‐shaped curve in terms of the cost of engaging in PI. As these differences reflect the manufacturers' incentive to innovate, the variations in R&D investment depend on transportation cost, and firms' marginal costs before and after successful innovations.     

STABILITY OF THAI BAHT: TALES FROM THE TAILS

We demonstrate how the EVT‐based signalling approach for currency crises can be applied to an individual country with a small sample size. Using Thai historical data, first, we study the tail characteristics of the distributions of two Thai baht instability measures and 21 economic fundamentals. Then, we test asymptotic dependence between the currency instability measures and lagged economic fundamentals. Empirically, we find that the distributions of both currency instability measures and economic variables are heavy tailed. Assuming a normal distribution for the variables tends to underestimate the probability of extreme events. Furthermore, most of the economic variables which are usually used as signalling indicators for currency crises are asymptotically independent of the currency instability measures. Signals issued by these variables are thus not reliable. Nevertheless, the non‐parametric EVT approach facilitates the selection of economic indicators with credible signals and high crisis prediction success.     

Surplus liquidity,central bank losses and the use of reserve requirements in emerging markets

Since the turn of the millennium, stocks of foreign reserves held by central banks in many emerging markets and developing countries have exceeded currency in circulation. To steer money market rates, these central banks have been absorbing liquidity from, rather than providing it to, the banking sector in their regular monetary policy operations. When interest rates in countries with major reserve currencies are low, the yield on foreign reserves is low. A higher interest rate on liquidity‐absorbing operations may expose central banks to losses. Although a central bank is not a profit‐maximizing institution, central bank losses can undermine the independence of the central bank. Using data for a large panel of central banks, this paper provides some evidence that central banks tend to apply low‐remunerated reserve requirements when profitability is at stake.
