中国汇率、利率、物价等相关关系研究

在经济运行过程中汇率、利率和物价三者关系紧密、相互影响,对经济的运行具有重大的意义。汇率的低估会引发物价上升,而实际汇率又由物价所决定。利率的变化对即期和远期的汇率也会产生重大的影响。我国的通货膨胀不仅应当通过抬高利率来抑制,更重要的应该通过对人民币正确估值,合理变动人民币汇率来解决。     

The impact of foreign interest rates on the economy: The role of the exchange rate regime

It is often argued that many economies are affected by conditions in foreign countries. This paper explores the connection between interest rates in major industrial countries and annual real output growth in other countries. The results show that high foreign interest rates have a contractionary effect on annual real GDP growth in the domestic economy, but that this effect is centered on countries with fixed exchange rates. The paper then examines the potential channels through which major-country interest rates affect other economies. The effect of foreign interest rates on domestic interest rates is the most likely channel when compared with other possibilities, such as a trade effect.     

Pricing and hedging of quanto range accrual notes under Gaussian HJM with cross‐currency Levy processes

This study analyzes the pricing and hedging problems for quanto range accrual notes (RANs) under the Heath‐Jarrow‐Morton (HJM) framework with Levy processes for instantaneous domestic and foreign forward interest rates. We consider the effects of jump risk on both interest rates and exchange rates in the pricing of the notes. We first derive the pricing formula for quanto double interest rate digital options and quanto contingent payoff options; then we apply the method proposed by Turnbull (Journal of Derivatives, 1995, 3, 92–101) to replicate the quanto RAN by a combination of the quanto double interest rate digital options and the quanto contingent payoff options. Using the pricing formulas derived in this study, we obtain the hedging position for each issue of quanto RANs. In addition, by simulation and assuming the jump risk to follow a compound Poisson process, we further analyze the effects of jump risk and exchange rate risk on the coupons receivable in holding a RAN. © 2009 Wiley Periodicals, Inc.

Cross country effects of sterilization,reserve currencies,and foreign exchange intervention

This study examines the international repercussions of national sterilization policies under fixed exchange rates and managed flexibility. Using a stochastic framework, the study shows how sterilization, or the use of a reserve currency with the automatic sterilization which that implies, modifies the impact of balance of payments disturbances on key financial variables in the domestic and foreign countries. In both exchange rate regimes, sterilization by the foreign country imposes costs on the domestic country by magnifying the impact of balance of payments disturbances on the domestic financial market.     

Exchange rate policies in Asia in an era of financial globalisation: An empirical assessment

Ebbs and flows of capital have complicated macroeconomic policy management for all emerging market and developing economies (EMDEs) regardless of whether they have adopted flexible or managed exchange rate regimes. In the light of the renewed interest in the trilemma versus dilemma debate, we contribute to the related literature by presenting an empirical analysis of exchange rate flexibility and intervention for selected Asian EMDEs over the time period 2001–2016. In addition to estimating augmented Frankel–Wei regressions, we employ a generalised auto‐regressive conditional heteroscedasticity (GARCH) model to assess the extent of foreign exchange (FX) intervention and whether there exist any asymmetries in the way countries intervene. Our results show that although there is greater flexibility in exchange rates, there is evidence of some countries potentially using FX intervention to manage currency movements. We also find evidence of asymmetry in intervention where exchange rate volatility responds more emphatically to FX sales than purchases.     

The short run efficacy of monetary policy under floating exchange rates reconsidered

This paper disputes the argument that the short-run effectiveness of monetary policy in stabilizing domestic output under floating rates is necessarily reduced if elasticities of demand for imports and exports with respect to the current exchange rate are low and capital flows depend on the exchange rate. It is shown that the relative efficacy of monetary changes is determined by the interest rate elasticity of international interest payments and receipts and the effect of exchange rate variations on the demand for money in addition to the exchange rate elasticities of trade and capital flows.     

Sterilisation and Monetary Control by the GCC Member Countries

The prevailing dollar peg of the Gulf Cooperation Council (GCC) countries and the absence of any significant current and capital account restrictions led some to believe that these countries have lost monetary independence. However, the paper presents evidence that interest rates of the GCC countries did not converge to the interest rates of the US implying that the assets of the GCC countries are not perfect substitutes to the US assets. This imperfect asset substitutability has allowed the GCC countries to manoeuvre their monetary policies and the central banks of the GCC countries have had some control over their money growth rates by sterilising the changes in international reserves. Results indicate that the monetary authorities of these countries used domestic credit policy to attain some domestic policy objective while engaging in sterilised foreign exchange intervention. This result implies that the proposed GCC central bank should be able to maintain the monetary independence as a group and can reap the benefit of monetary efficiency of the proposed Gulf Monetary Union.     

Foreign monetary shocks,differentiated products and international transmission: a two-country model with intra-industry trade

In this paper we study how the impact of a foreign monetary shock is transmitted between two monopolistically competitive economies engaging in intra-industry trade with differentiated products. Intra-industry trade is the only international link that works through the flexible exchange rate affecting national price levels and a product's internal and external relative prices. While national price levels are subject to purchasing power parity, the two relative prices are determined by the interaction between macro and micro variables. In this context, the exchange rate can insulate a national economy perfectly from a foreign monetary shock provided that monopolists adjust prices. Even if monopolists keep prices rigid, this shock only affects domestic real balances and aggregate demand, leaving domestic aggregate output unchanged because the real balances effect is just offset by the resulting unfavorable relative prices effects under the assumption of Spence-Dixit-Stiglitz preferences.     

The evolution of trading activity in Asian foreign exchange markets

We exploit previously unpublished data on foreign exchange turnover to analyse the institutional setting in which the currencies of non-Japan Asia are traded. Volumes grew rapidly between 2004 and 2007 and the diversity of market participants increased. Nevertheless, liquidity is undermined by foreign exchange controls. For Asian currencies other than JPY, HKD and SGD, non-residents account for a relatively small share of activity and FX swap markets are still in their infancy. Offshore non-deliverable markets have developed in response to controls, causing segmentation in trading activity. Furthermore, Herstatt risk remains high in Asian foreign exchange markets.

Exchange rate jumps and exports: Evidence from China

We apply the autoregressive conditional jump intensity (ARJI ) model to monthly exchange rate returns of China against 81 countries and investigate the impact of exchange rate volatility on exports over the period of 1995–2004. We decompose bilateral exchange rate volatility into continuous and discrete components and find that only the discrete part of exchange rate volatility, that is, the exchange rate jumps, has a significantly negative effect on exports, which to some extent reconciles the old yet unsettled debate in previous literature on the role of exchange rate volatility in international trade. There is also some evidence suggesting that the development of domestic financial market will boost international trade, but it does not help attenuate the negative effect of bilateral exchange rate jump risk on exports.     

Geographical Location of Foreign Direct Investment and Wage Inequality in China

This paper examines the relationships between distance and the transportation costs of international trade on the location‐specific effects of foreign direct invest‐ment and provincial per capita income in China. Applying the economic geography model proposed by Redding and Venables (2004), it traces the increasing wage inequality among the coastal and inland provinces by focusing on the distance of foreign‐owned firms from access to international markets and to suppliers of intermediate inputs. First, a gravity‐type equation is used to construct the ‘market access’ and ‘supplier access’ variables. Then, the effect of market and supplier access on provincial wage rates is estimated. The results indicate that distance does affect international trade and geography explains roughly one‐third of the wage differential. Greater market access increases the provincial wage gap, while larger supplier access increases the wage difference in trade destined for the foreign market but decreases the wage difference in trade targeted for the domestic market. Similar findings also result from applying the estimations to two local firm types: state‐owned enterprises and collective‐owned enterprises.     

Who bears the cost of a change in the exchange rate? Pass-through accounting for the case of beer

Nominal exchange rates are remarkably volatile. They ordinarily appear disconnected from the fundamentals of the economies whose currencies they price. These facts make up a classic puzzle about the international economy. If prices do not respond fully to changes in the nominal exchange rate, who bears the cost of such large and unpredictable changes: foreign firms, domestic firms, or domestic consumers? This study presents a new analysis of the sources of incomplete pass-through and then uses this analysis to re-examine its implications for social welfare. I develop and estimate a structural model that analyzes the sources of local-currency price stability for a particular industry. The model enables counterfactual simulations that quantify the relative importance of firms' local-cost components and markup adjustments in the incomplete transmission of exchange-rate shocks to prices and the effect of the exchange-rate shock on domestic and foreign firms' profits and on consumer surplus. The model is applied to a panel dataset of one industry with retail and wholesale prices for UPC-level products. I find that markup adjustments by manufacturers and the retailer explain roughly half of the incomplete transmission and local-cost components account for the other half. Foreign manufacturers generally bear a greater cost (or reap a greater benefit) following an exchange-rate-induced marginal-cost shock than do domestic consumers, domestic manufacturers, or the domestic retailer.

Imperfect asset substitutability and monetary policy under fixed exchange rates

This paper presents a long-run model of the open economy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. The model explicitly accounts for the wealth flow accompanying current-account imbalance and for the flow of interest payments associated with international lending. Both the dynamic and steady-state implications of the model are quite different from those of models that specify the capital account as a continuing flow responding to the level of interest rates. In particular, we find that when there exists outside government debt, open-market policy is not in general neutral in the long run. We also find conditions under which the central bank is able to hold the domestic price level constant in the face of an inflationary disturbance from abroad without exhausting, in the long run, its stock of domestic assets.     

Teaching the Linkages Between the International Credit and Foreign Exchange Markets

ABSTRACT

This paper presents a teaching model which provides an analytical framework that encourages students to think about economic events in a global context. It ties the international credit and foreign exchange markets together and shows how international capital flows represent the crucial linkage between them. This model is primarily a teaching tool which illustrates how changes in monetary and fiscal policies in one country, say Japan, impact world interest rates, exchange rates, and trade and capital imbalances for other countries. This approach can also be used to illustrate the impacts of changes in savings and investment behavior by businesses and households, as well as central bank interventions.     

论汇率的决定机制、波动区间与政策搭配

本文论证了汇率的可行波动区间是由经济因素、国际政治经济博弈共同决定的；提出了大国之间在汇率问题上的博弈，只是大国经济关系再调整的一个反映，并据此得出了各方在人民币汇率问题上的博弈具有长期性的结论；本文指出，汇率的可行波动区间应选取在公共区间的右侧，以期实现国内经济、国际收支、国际政治经济博弈的三重均衡；在总结日本与德国经验教训的基础上，提出在货币升值的过程中，应采取适度从紧的财政政策与货币政策，避免短期内的大幅升值，维持较高的实际利率，防范不动产资产对于银行存款的过度替代，防止出现严重的不动产泡沫。     

Real and Financial Sector Interaction Under Liberalization in an Open Developing Economy

A short‐run model incorporates instantaneous portfolio equilibrium with macroeconomic flows to clarify the structure of real–financial sector interactions. If equity and foreign exchange markets are introduced in structuralist theories of asset markets in developing countries, the key result that a fall in money supply raises the rate of inflation now holds only under special conditions on partial derivatives. But there is a tendency for interest rates to rise and for fluctuations in asset prices. Fuller integration of asset markets moderates these fluctuations. Outcomes are stable in spite of the generalized complementarity distinguishing equity markets from loan markets. Expectations play a major role. Implications for policy are to link domestic interest rates to foreign, remove artificial barriers to market integration, and stimulate demand as well as supply.     

Dissecting the dynamics of the US trade balance in an estimated equilibrium model

In an estimated two-country DSGE model, we find that shocks to the marginal efficiency of investment account for more than half of the forecast variance of cyclical fluctuations in the US trade balance. Both domestic and foreign marginal efficiency shocks generate a strong effect on the variability of the imbalance, through shifts in international relative absorption. On the other hand, shocks to uncovered interest parity and foreign export prices, which transmit mainly via the terms of trade and exchange rate, have a strong influence at short forecast-horizons, before the investment disturbances begin their dominance.     

Unveiling the effects of foreign exchange intervention: A panel approach

The paper studies the effect of foreign exchange intervention on the level of the exchange rate relying on an instrumental-variable panel approach suited to assess the macroeconomic importance of such effect (i.e., beyond short-term effects found in the literature). We find robust evidence that intervention affects the exchange rate in a meaningful way from a macroeconomic perspective. A purchase of foreign currency of 1 percentage point of GDP causes a depreciation of the nominal and real exchange rates in the ranges of [1.7–2.0] percent and [1.4–1.7] percent, respectively. The effects are found to be persistent and symmetric for FX purchases and sales.
