Short-Run and Long-Run Dynamics of Exchange Rates with Sticky Prices

This paper constructs microfoundations for the nexus between sticky goods prices and exchange rate overshooting. Based on an asset-pricing model, this paper describes how the exchange rate responds to a monetary shock in the short run and adjusts in later periods to a new long-run rate. In an environment where goods prices are sticky, the short-run response of the exchange rate to a monetary shock depends on the elasticity of consumption demand. The long-run exchange rate always shifts equiproportionately to a monetary shock regardless of the parameter values and is reached many periods after the shock.     

The Effects of Macroeconomic Policies in a Mercantilist Economy

By introducing money and foreign exchange in the Zou (1997) model of mercantilism, the paper shows the effects of macroeconomic policies in mercantilist economies. It is shown that in the long run, consumption and foreign asset accumulation increases as a result of stronger mercantilist sentiments, permanent increases in the consumption tax, increases in the monetary growth rate and purchases of foreign bonds. In the short run, however, macroeconomic disturbances including the mercantilist sentiments, the monetary growth rate, and the consumption tax have negative effects on current consumption and positive effects on current foreign asset accumulation, while purchasing foreign bonds has positive effects on both current consumption and current foreign asset accumulation. The theoretical explorations may provide a theoretical structure for hoarding international reserves and export-led growth strategy utilized by emerging market economies.     

实际外部财富、劳动生产率与人民币实际汇率——基于跨期一般均衡理论的实证研究

本文首先构建关于实际外部财富、劳动生产率、贸易条件与实际汇率关系的跨时一般均衡理论模型,然后利用1981-2009年相关时间序列数据,检验中国实际外部财富、贸易条件以及国内外两部门劳动生产率对人民币实际汇率的影响。结果表明,从长期看,中国实际外部财富的急剧攀升会引发人民币实际汇率快速升值;中国贸易部门相对非贸易部门劳动生产率上升会促使人民币实际汇率升值,而国外贸易部门相对非贸易部门的劳动生产率提高则会降低人民币实际汇率,净效应表现为劳动生产率并不能解释20世纪80年代以来人民币实际汇率的长期波动;中国贸易条件对人民币实际汇率的影响不明显。短期内,中国实际外部财富对人民币实际汇率的作用关系与长期一致。根据上述结论,本文提出了保持人民币实际汇率相对稳定的政策建议。     

Exchange Rate Hysteresis: The Effects of Overshooting and Short-Termism

The present paper addresses two questions. First, how does exchange rate overshooting affect hysteresis in trade and competitiveness? Second, how does 'short-termism' alter the magnitude of such hysteresis effects? The paper models the dynamic processes of hysteresis in trade and competitiveness in terms of the presence of discrete, asymmetric lump-sum costs of entry, in response to unanticipated foreign policy shocks. The paper produces some important new insights into the role of short run adjustment processes in understanding persistence effects in key macroeconomic indicators.     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

The Effects of Capital Controls on Exchange Rate Volatility and Output *

This paper extends the Dornbusch model of overshooting exchange rates to discuss both exchange rate and output effects of capital controls that involve additional costs for International asset transactions.We show that, on the one hand, such capital controls have the merit of reducing the volatility of exchange rate volatility in the sort run and induces costs for the real sector in the form of lower equilibrium output levels.

The Transfer Problem and Real Exchange Rate Overshooting in Financial Crises: The Role of the Debt Servicing Multiplier*

We develop a real model of exchange rate overshooting due to a debt servicing multiplier. Borrowers of foreign capital are bound by noncontingent contracts to pay the world rate of return following an adverse shock. This is onerous, since the marginal product of capital is less than the world rate of return and the shock causes some capital to become extra‐marginal. If the resultant debt servicing shortfall is met by taxes on workers, this reduces their demand for nontradable goods, which feeds back onto their wage, reducing their demand for nontradable goods, etc. In the short run, when extra‐marginal projects are “stuck” in the economy, the real exchange rate can overshoot. This mechanism may help to explain overshooting of exchange rates in the 1997 Asian financial crisis.     

When is money neutral under flexible exchange rates?

The paper studies the conditions for the neutrality of money under flexible exchange rates in an extended real-wage Mundell–Fleming model, with special emphasis on the specification of the behavior functions to correspond to their foundations in closed-economy macrotheory.It is shown that monetary expansion causes output first to decline, to eventually rise above its original level. However, if interest earnings on foreign securities dominate the trade balance in the expression for the exchange rate, monetary expansion leads to an appreciation of the exchange rate, while having an expansionary output effect. Money is neutral in the long run if either the wealth effect or foreign interest payments are abstracted from; if both are abstracted from, it is neutral also in the short run. Short and long-run neutrality results also if wealth consists only of foreign securities. The above responses hold both for net creditors and – with a minor qualification – debtors.     

Wealth effects on the housing markets: Do market liquidity and market states matter?

This paper analyzes the effect of household wealth (including housing and financial wealth) on housing sales and probes their long-run and short-run dynamic relationships. We further examine the short-run effect of financial wealth on housing sales by employing quantile regressions, restricted upon different liquidity (quantile) levels and up-down housing markets, from which the differences between the early and late stages of an uptrend/downtrend can be respectively exhibited. We find that housing wealth, income, and mortgage rates have long-run influences on housing sales. Looking at the short run, we find that housing sales only respond to housing wealth and mortgage rates. When we distinguish the effects of financial wealth on housing sales in up-down housing markets, we note a positive influence of financial wealth on housing sales in down markets, but not in up markets. Particularly, our results show an impact of housing liquidity on the short-run relationships.     

The Taylor Rule,Wealth Effects and the Exchange Rate

In this study, we develop the Taylor rule and Taylor rule‐based exchange rate models that consider wealth effects as represented by both asset prices and asset wealth. Using data for Australia, Sweden, the UK and the USA, we find that effects of asset prices and wealth on the Taylor rule vary depending on the country and on the form that wealth takes. Out‐of‐sample forecasting capacities of the wealth‐augmented Taylor rule model and Taylor rule‐based exchange rate model outperform conventional models and random walk theories for these countries.     

Inflation targeting in an import dependent indebted economy

This paper develops a one-sector Kaleckian model of an import dependent indebted small open economy; where the mark-up rate is sensitive to both changes in the interest rate and the exchange rate and foreigners provide part of the long-term finance. The short-run consequences of an inflation targeting policy in the form of high interest rates and strong domestic currency are explored. Among the possible short-run scenarios, the one most relevant for developing countries involves a decline in the profit rate, the capacity utilization rate and the rate of accumulation as well as the employment rate and the real wage. Leverage ratio of the firms and the extent of external indebtedness play an important role in bringing about this result. Long-run analysis reveals that this scenario is associated with instability in the long run and that, also in the long run, the extent of foreign indebtedness and the responsiveness of capital inflows to the return on existing portfolios are important in determining the direction of the effects of inflation targeting on the equilibrium debt–capital ratio.     

金融资产与实物资产对城镇居民消费影响的差异性研究

本文在相关资料基础上,对我国城镇居民持有金融资产与实物资产进行了重新核算,并采用ARDL-UECM模型计量分析了长短期内金融资产、实物资产对消费影响的差异性。结果表明:金融资产长期内对消费支出存在较弱的抑制作用,短期内存在较弱的促进作用;而实物资产长期内对消费存在有限的促进作用,短期内对消费存在较强的促进作用。产生这种差异的原因主要是:超额比重预防性储蓄导致金融资产对居民消费产生长期扭曲,以及过高自有住房率在房价攀升时只能提高短期边际消费倾向,长期则有限。现阶段只有降低超额比重预防性储蓄及抑制过高的房价才能进一步提高城镇居民的资产财富效应。     

Modeling Exchange Rate Volatility

This paper investigates the impact of the volatility of the underlying macroeconomic fundamentals on exchange rate volatility utilizing the bounds testing approach to cointegration. The results show that, in the long run the volatility of the money supply is the sole determinant, whereas in the short run overshooting is found.     

Financial Globalization,Financial Crises,and the External Portfolio Structure of Emerging Markets*

We study the transitional dynamics of financial integration in emerging economies using a two‐sector model with a collateral constraint on external debt and trading costs incurred by foreign investors. The probability of a financial crisis displays overshooting; it rises sharply initially and then falls sharply, but remains non‐zero in the long run. While equity holdings fall permanently, bond holdings initially fall, but rise after the probability of a crisis peaks. Conversely, asset returns and asset prices first rise and then fall. These results are in line with the post‐globalization dynamics observed in emerging markets, and the higher frequency of crises that they display.     

WEALTH,ASSET PORTFOLIO,MONEY DEMAND AND POLICY RULE

I look at the linkages between monetary policy and asset wealth using quarterly data for the USA. I show that a positive interest rate shock leads to a fall in aggregate wealth and an important change in portfolio composition: housing wealth gradually decreases, but the effects are very persistent; and financial wealth quickly shrinks, but the impact is short‐lived. I also find that the money market can be characterized as follows: (i) the money demand has a large interest elasticity and a small output elasticity; and (ii) the estimated monetary policy reaction function highlights the special focus given by the central bank to developments in monetary aggregates. These features call for an approach whereby monetary authorities put more emphasis on tracking wealth developments, in particular, given the asset portfolio rebalancing between money holdings and financial and/or housing assets.     

The effects of exchange rate volatility on exports: evidence from Armenia

The article examines how the volatility of exchange rate affected Armenia’s export to its main trading partner, Russia, in the period from January 2007 to February 2016. Along with real foreign income and competitiveness, the exchange rate volatility is considered as a determinant of real export. The estimation results indicate that the exchange rate volatility has negative significant effects on real export both in the long run and in the short run.     

Malaysia-Japan Commodity Trade and Asymmetric Effects of Exchange Rate Changes

Asymmetry analysis is a new norm in applied research and the link between the trade balance and the exchange rate is no exception. In this paper we investigate the asymmetric response of the trade balance of each of the 60 industries that trade between Malaysia and Japan. We find short-run asymmetric effects of exchange rate changes on the trade balance of 50 industries (including the two largest industries), short-run adjustment asymmetry in 47 industries, and short-run impact asymmetry in 30 industries. However, short-run asymmetric effects lasted into the long run only in limited number of industries. Results are industry-specific at best.     

Stock market wealth effects in an estimated DSGE model for Hong Kong

This paper develops and estimates an open-economy dynamic stochastic general equilibrium (DSGE) model of the Hong Kong economy. The model features short-run price rigidities generated by monopolistic competition and staggered reoptimization. We devote special attention to asset prices and wealth effects, which we believe to be important. For this reason we adopt a perpetual-youth approach. Model parameters and unobserved components are estimated with a Bayesian maximum likelihood procedure, conditional on prior information concerning the values of parameters. The estimations identify substantial wealth effects and indicate that the nominal interest rate responds to unexpected movements in stock prices.     

The Sensitivity of U.S. Inpayments and Outpayments to Real Exchange Rate Changes: Asymmetric Evidence From Africa

ABSTRACT

A strand of the literature concentrates on assessing the impact of exchange rate changes on a country’s inpayments from and outpayments to its trading partners. Most studies have considered the U.S. experience with partners from OECD but not for those from Africa. We fill this gap by including 14 African partners in our study. We assess not only the symmetric effects of exchange rate changes on the U.S. inpayments from and outpayments to each African partner, but also the asymmetric effects which requires incorporating nonlinear adjustment of the exchange rate. While we found asymmetric effects in the trade with almost all partners in the short run, in a limited number of cases the short-run effects lasted into long-run asymmetric effects. All in all, our findings are partner specific, but they provide more support for using nonlinear models.     

人民币汇率、资产价格与短期国际资本流动

本文基于1999年1月～2008年6月的月度数据,运用ARDL-ECM模型检验了人民币汇率、资产价格与我国短期国际资本流动的关系。结果表明,长期内,人民币汇率预期变化率和国内外利差是影响短期国际资本流动的显著因素,人民币汇率水平、国内股市收益率和房地产收益率并未对短期国际资本流动产生显著影响;短期内,人民币汇率、国内外利差和房地产收益率对短期国际资本流动有显著的滞后效应。
