Portfolio stock adjustment and the real exchange rate: The Dollar-Mark (DM) and Mark-Sterling

The advent of “freely floating” exchange rates in the 1970's coincided with the emergence of what is known as “monetary” or “asset” models of exchange rate behavior where exchange ratesmove to equilibrate demand for stocks of monies. The fundamental monetary model assumes purchasing power parity holds in the long-run, and therefore exchange rates are determined by the same factors that determine relative prices, to wit, money stocks, real incomes, and nominal interest rates. Though early proponents of the monetary view clearly emphasized its long-run nature, empirical testing has by and large neglected this caveat. Thus a model developed for long-run equilibrium exchange rates has instead been tested many times over on short-run equilibrium rates. The latter require a distinct model of their own. This paper develops a short-run equilibrium exchange rate model based on deviations of the short-run exchange rate from its long-run equilibrium. The model differs in that all variables are cast in real terms. It also differs in that the monetary and current account exchange rate versions are shown to be subsets of the more general wealth/portfolio framework used here. The present model considers, in addition to stocks of monies, stocks of foreign assets, and stocks of domestic wealth.     

Debt, deficits and the dollar

This paper examines the relationship between the budget deficit and the trade deficit in the United States by presenting new evidence on the impact effects of debt disturbances on the exchange rate. Based upon estimates of a general two-country portfolio-balance model, we find evidence that increases in the U.S. debt stock have caused an appreciation in the U.S. dollar relative to the German mark and the Canadian dollar over the period 1973II–1987II. Correspondingly, this paper presents evidence on the linkage between the budget deficit and the trade deficit arising through the exchange rate.     

Inflation,oil prices and exchange rates. The Euro’s dampening effect

This paper aims to analyse the relationship between the euro/dollar exchange rate and oil prices and examine what effect this relationship had on the transmission of oil price fluctuations to headline inflation in the euro area since the currency’s creation. We estimate an augmented Phillips curve including changes in oil price, through which we study the role of the exchange rate in oil price pass-through by using different specifications. The main findings reveal a positive relationship between the euro/dollar exchange rate and oil prices, such that an increase in the price of oil is followed by an appreciation in the euro. We also find that the transmission of oil price fluctuations to headline inflation in the euro area has been partially dampened by this appreciation in the euro/dollar exchange rate. These results do not hold for other economies with internationally relevant currencies, such as Japan and the United Kingdom. These findings have important implications for the implementation of monetary policy in the euro area in the face of oil price shocks.     

Effects of fiscal policy on the U.S. economy: Empirical estimates of crowding out

This study examines the short-and intermediate-run effects of a permanent reduction in U.S. personal income taxes on interest rates, output, prices, exchange rates, and the current account, holding government spending and money growth fixed. The theoretical analysis suggests that interest rates and domestic consumption will rise but that net exports and interest-sensitive expenditures will fall. Also, the foreign currency value of the dollar will rise except possibly when output increases due to positive supply-side effects or to elimination of unemployment. These theoretical conclusions are essentially confirmed by simulations using the Federal Reserve Board's MPS quarterly econometric model and its multicountry model.     

An analysis of the welfare implications of alternative exchange rate regimes: An intertemporal model with an application

This paper develops a methodology for evaluating the short-run welfare implications of different exchange rate regimes. Heterogeneous, optimizing domestic consumers live for two periods, consume goods and leisure, supply labor, save home and foreign bonds, and demand currency. Firms maximize profits. The home government levies taxes, issues money and bonds and supplies public goods. The foreign country demands imports, supplies exports, and lends to the home country. The theoretical model is estimated for Australia. Counter-factual simulations are carried out. The results suggest that floating was, or would have been, the superior regime for the 1981–1984 period.     

Policy modeling of foreign exchange rates

This paper is neither a complete survey of empirical work on exchange rate determination, nor a review of the ballooning volume of theoretical models. It is instead an attempt to classify the main alternative approaches to modeling exchange rates. I shall concentrate on approaches that can be used to assess the effects of alternative policies. There will be four further sections in the paper. The first three sections will each deal withthe structure, empirical support, and policy consequences of three main types of model: purchasing power parity models emphasizing the close and immediate relation of goods markets; interest rate parity models emphasizing the close and immediate international linkage of markets for financial assets; and structural balance-of-payments models that do not assume either of the above linkages to be so strong and immediate as to eliminate the other, and that hence require separate (but interdependent) modeling of trade and capital linkages in the determination of exchange rates. Each of these main categories has many rather distinct models within it, and some models are not easily classified into one of the three categories; I hope that the three-way split will nevertheless serve to make some distinctions that are important for policy modeling.In the final section I shall try to summarize the available model results that pertain to national and international policy choices under a system of more flexible exchange rates, and then to suggest where more or better model building might usefully increase the amount of information available to guide policy decisions.     

Dollar appreciation,deficit stimulation,and the new protectionism

This article probes whether contemporary U.S. protectionism arises from an appreciating dollar. It concludes that (a) an enrich-thy-neighbor policy of upvaluation has transformed the current U.S. economic recovery into an engine of global recovery; (b) flexible exchange rates continually equilibrate the balance of payments as evidenced in changed domestic—relative to foreign—prices, as well as in capital movements induced by interest-rate differentials resulting from exchange-rate shifts; and (c) flexible exchange rates automatically alter so as to maintain a country's competitive position in the world economy even when facing deficits at home and abroad.     

North-South relations: Alternative policy simulations for the world economy in the 1980s

This article makes projections of the world economy in the North-South context for the period 1981–1990 using a latest global version of a macroeconomic model named FUGI-GNEM type IV 011–62. The model classifies the world into 62 countries/regions, where the North-South interdependence is incorporated into an integral part of the world economy through international economic linkages. Based on alternative simulations, the author presents future images of the North-South interdependent world economy through changes in economic growth rates, employment, wages, prices, money supply, interest rates, public finance, trade, capital movement, international balance of payments, foreign exchange rates, etc., in each country or region. The model forecasts that the real economic growth of the developing countries as a whole in the 1980s will likely be around 4%–7% annual rate according to alternative policy scenarios.     

Capital mobility among advanced countries

Mobility of capital has been studied by examining savings–investment correlations, real interest rates differentials, covered and uncovered interest parity, and equity home bias. All these examine the capital mobility question indirectly. This paper directly tests the return/total flow specification of the Mundell–Fleming model. It finds that while portfolio equity and debt flows are, direct investment is not; and in every case, the inclusion of direct investment makes the aggregative-capital variable unresponsive to interest rates. Asset-based exchange rate models may benefit by looking at the composition of cross-border assets, countries can have independent monetary policies with full capital mobility, and macroeconomic policy trilemma for open economies disappears.     

Productivity growth,external shocks,and capital inflows in Chile: A general equilibrium analysis

This paper uses a computable general equilibrium model to analyze the growth path of the Chilean economy during 1977–1981. During that period a comprehensive package of reforms liberalized international trade and removed restrictive labor legislation. As a result of the reforms, there were large changes in relative prices and in the structure of production and demand, and the economy enjoyed unprecedented growth with declining inflation. But large macroeconomic imbalance become evident toward the end of the period and in 1982 Chile experienced an abrupt and severe recession. Taking the real exchange rate as an exogenous policy variable, and using the observed levels of employment growth and foreign capital inflows, this paper compares model-generated growth paths with those of the economy. First, the benchmark simulation path is used to estimate the magnitude and pattern of growth and productivity change during the 1971–1981 period. Next, counter-factual simulations are used to assess how Chile's economic performance would have differed if (a) external events had been different; and (b) foreign capital inflows had been different. The analysis suggests that the macroeconomic imbalances that led to the crisis in 1982 were exacerbated by the large capital inflows and real exchange rate appreciation that resulted from the use of the exchange rate as a stabilization device.     

Re-estimation of China＇s Degree of Trade Dependence and External Imbalance： Value-added Statistics in the Global Production Chain＊

GDP与外贸数据的扭曲夸大了中国外贸依存度及外贸失衡度。GDP的扭曲主要来自汇率法与购买力平价法估算的差异；贸易数据扭曲包括：关境统计的重复计算以及由产权问题导致的国际贸易物流与资金流的不一致。对2007年我国实际外贸依存度及其失衡度的重估显示：2007年中国的外贸依存度从官方统计的68．02％下调为31．59％，外贸失衡度也从官方统计的10．13％下调为2．11％。所谓“中国操纵汇率”的指责是毫无根据的。     

Asymmetric price rigidity and the optimal interest rate defense of the exchange rate: Some evidence for the US

This paper analyses the optimal monetary policy under incomplete exchange rate pass-through and asymmetric price rigidity. In a general equilibrium sticky price model of an open economy we find that the optimal interest rate rule is to respond to all types of shocks in an economy: real exchange rate shocks, supply shocks and demand shocks. We concentrate our analysis on the interest rate defense of the currency. We claim that the extent of the optimal response of the interest rate to exchange rate shocks depends positively on the degree of pass-through and negatively on price rigidity. Therefore, in the presence of asymmetric price rigidity, the optimal monetary policy should be non-linear, and the interest rate should be adjusted more in case of depreciation of the domestic currency than in case of its appreciation by the same magnitude due to higher downward price rigidity and lower downward pass-through, which are observed empirically. We test this prediction for the US economy and find that the US monetary policy is asymmetric indeed with higher reaction of the interest rate to depreciations of US dollar than to appreciations of the same size.     

The real uncovered interest parity: The case of Canada and the USA

The aim of this paper is to re-assess the real uncovered interest parity (RUIP) in the light of including domestic demand shocks as possible determinants of the real exchange rate. We use annual data for two close trading partners, namely Canada and the USA. Using cointegration analysis we find evidence in favour of RUIP. In addition, empirical support is provided to show that discretionary fiscal policy actions have a spillover effect to the real exchange rate via real interest rates.     

A model of the Canadian global exchange rate: A test of the 1970s

This comment points out some methodological weaknesses in the Canadian global exchange rate model and the associated efficiency tests of Marwah and Bodkin. The model is found to be inadequate for policy analysis.     

Asset markets and foreign exchange intervention: A model of the Belgo-Luxemburg economic union

In this article a general formulation of government intervention policies in the foreign exchange market is integrated in the framework of an asset market model. The policy reaction function is based on a trade off between exchange rate and reserve stock fluctuations; constant exchange rates and a pure float are derived as limiting cases of the intervention schedule. An exchange rate equation is derived from the short run portfolio equilibrium of the model and is successfully tested using data for the Belgo-Luxemburg Economic Union (1967–1979). Our policy conclusions contrast the European Snake constraints for the Belgian Franc with Artus's findings (IMF Staff Papers XXIII(2), July 1976) for the leading DM.     

Alternative specifications of the demand for money and their implications for forecasting and policy analysis with large macroeconomic models

The demand for money is an important function in large macroeconomic models because of its central role in monetary policy. The interest rate responsiveness of money demand determines the interest rate changes consistent with the initial change in monetary policy and the subsequent changes on aggregate demand and the price level. This paper uses the DRI macroeconometric model to investigate these issues, finding that the model's predictive power and its estimates of the relative potency of monetary and fiscal policy are dependent upon the specification of the money demand function.     

The role of macroeconomic policies in the global crisis

This paper argues that the lack of timely and decisive policy action to correct domestic and external imbalances contributed crucially to the build-up of financial excesses that led to the financial crisis and the Great Recession. We focus on 2002–2007 and perform a number of counterfactual simulations to investigate two central elements of the story, namely: (a) an over-expansionary US monetary policy and the absence of effective macro-prudential supervision, which permitted a prolonged expansion of debt-financed consumer spending and (b) the choice by China and other emerging countries to pursue an export-led growth strategy supported by pegging their currencies to the US dollar, in conjunction with sluggish domestic demand in major advanced economies characterized by low potential output growth. The results of the simulations lend support to the view that if substantial, globally coordinated demand rebalancing had been undertaken early on, the macroeconomic and financial imbalances would not have accumulated to the extent that they did and the financial turmoil might have had less drastic global consequences.     

Does gold act as a safe haven against exchange rate fluctuations? The case of Pakistan rupee

Investors often look for a refuge to avoid undesirable exposures to risk during period of extreme downturns in currency returns. We investigate daily gold and rupee exchange rates depreciation against set of currencies over the period of 1992–2015. Using wavelets at multiple time horizons; we find that gold act as a consistent short run hedge against exchange rate hence validating the exchange rate destruction hypothesis. This finding is helpful for speculators in their decision making while taking long and short positions accordingly. This finding suggests that central bank also need to keep other safe haven assets in reserves because the hedging ability of gold is only limited to short run. Further, the role of gold in providing protection against currency risks is also confirmed using quantile regression. These results assist portfolio managers and governments in formulating effectual diversification strategy for preserving investment portfolio during extreme event condition. Our results also suggest that gold has a lead relationship with exchange rate; however, this relationship switches over specific time intervals. This finding is of major concern for policy makers in determining the extent of stabilization in gold prices to bring consistency to exchange rate. Finally, the Granger coherence coefficients confirm that the strength of the causal relationship varies across over all frequencies. These conclusions have important implications for policy makers, economic analysts, portfolio managers and institutional investors.     

On Primary Commodity Prices: The Impact of Macroeconomic/Monetary Shocks

The hypothesis of a long-run quantifiable relationship between non-oil primary commodity prices and macroeconomic/monetary variables—focusing industrial production and effective exchange rate of the US dollar—is tested by cointegration technique using quarterly data for 1970q2–93q3. This confirmed equilibrium adjustment explains the origin of the observed coincidence of commodity price variations with the fluctuations of macroeconomic/monetary variables. An error correction specification, including interest rate, is therefore applied to estimate the observed disequilibrium prices of commodities in the context of steady-state solutions. This instantaneous adjustment explains why commodity prices have fluctuated more strongly over the last 2 decades than before.     

Agriculture,trade, and macroeconomics: The U.S. case

The persistent appreciation of the U.S. dollar from 1980 through 1984 raise the issue of macroeconomic impacts on trade sectors as a critical policy concern. In this article a six-variable vector autoregressive model is utilized to evaluate the dynamic effects of macroeconomic shocks on U.S. agriculture, a key trade sector. The results suggest that the impacts are substantial. Expansion of the money supply or a decline in the real interest rate or the real value of the dollar has a positive effect on agricultural exports and relative prices, whereas autonomous inflationary shocks have negative effects.
