Does Economic Policy Uncertainty Affect Exchange Rate in China and Japan? Evidence from Threshold Cointegration with Asymmetric Adjustment

In this article, we estimate the links between nominal exchange rates (JPY/USD and CNY/USD) and economic policy uncertainty (EPU) in China and Japan by employing monthly data during the period span from January 1997 to September 2020. The threshold cointegration approach focus in TAR, M-TAR, C-TAR and C-MTAR is used. Results indicate the evidence of asymmetric effect in the adjustment process to equilibrium and the M-TAR is the best model to detect threshold effect for the (CNY/USD-CNYEPU) pair and the C-TAR is the best model to detect threshold effect for the (JPY/USD-JPYEPU) pair.

Nonlinear Cointegration and Asymmetric Adjustment in Purchasing Power Parity of the USA, Germany, and Pakistan

The current study explores nonlinear cointegration as well as asymmetric adjustment to investigate the long-run purchasing power parity in three major trading partners of Pakistan. The ESTAR and LSTAR models were used to investigate the behavior of the nominal exchange rates. The findings declared that series follows the nonlinear exchange rate. The asymmetric behavior of the exchange rate allows the threshold cointegration model to be implemented. In the case of Pakistan-China, the result suggests that long-run PPP holds. As a result, trading will be more profitable if the exchange rate is varied in relation to major trading partners rather than just the US dollar.

EXOGENOUS INTEREST RATE AND EXCHANGE RATE DYNAMICS UNDER ELASTIC EXPECTATIONS

<div class="WordSection1"><h1 align="center"><strong style="font-size: 10px;">ABSTRACT</strong></h1></div><p>A theory analyzing the short run dynamics of nominal exchange rates under exogenous interest rates and free imperfect international capital markets is presented. Introducing elastic exchange rate expectations leads to cumulative changes in the spot and forward exchange rates in the same direction. We find that free floating exchange rate regimes are intrinsically unstable, as the nominal exchange rate is an institutional or policy variable that has no ‘fundamental equilibrium’ level. Implications for monetary policy and exchange market interventions of this potential instability are derived. Our results help to explain both the empirical prevalence of dirty floating exchange rate regimes and some aspects of the uncovered interest parity ‘failure’.</p><p> </p><p align="center">TASA DE INTERÉS EXÓGENA Y DINÁMICA DEL TIPO DE CAMBIO CON EXPECTATIVAS ELÁSTICAS</p><p align="center"><strong>RESUMEN </strong></p><p>Presentamos un análisis teórico de la dinámica de corto plazo de los tipos de cambio nominales con tasas de interés exógenas y libres e imperfecta movilidad internacional de capitales.

How the macroeconomic conditions and the global risk factors affect sovereign CDS spreads? New Evidence from Turkey

This paper aims to investigate the effects of a set of major country-specific macroeconomic variables and global risk factor on determining Turkey’s sovereign CDS spreads. The industrial production index, consumer price index, nominal exchange rates, policy interest rate, stock market index, and the volatility index as a proxy for global risk appetite are used by employing SVAR methodology with block exogeneity for 2011M01-2020M09 periods. The results reveal that the country's nominal exchange rate is the main driver of sovereign CDS spread. Especially in 2018, the most significant source of the high increase in sovereign CDS spreads is the exchange rates. According to the impulse response functions, to reduce the sovereign CDS spread, economic growth is more effective than the stock market return. Moreover, it is seen that the global risk factor does not play an essential role in the increases in domestic country's sovereign CDS spread.

Nominal exchange rates EUR/GRD and EUR/ITL in the context of leaving the euro zone by Greece and Italy

Aim/purpose – The aim of this paper is to present two cases of crises in Greece and Italy and to evaluate the shadow exchange rates of hypothetical new currencies (re)introduced after Grexit and Italexit. Design/methodology/approach – Both shadow exchange rates are estimated using speculative pressure index concept that emphasizes the importance of changes in foreign exchange reserves and interest rate differentials in the absence of an independent nomi- nal exchange rate. The research sample covers Greece in 1989-2020 and Italy in 1989- 2020. Findings – The research presented the estimation of shadow exchange rates EUR/GRD and EUR/ITL during the euro zone membership period. Leaving the euro area one can expect the following market rates: EUR/GRD 600 and EUR/ITL 1850. That would mean 75% depreciation and 5% appreciation to the current euro parities EUR/GRD 340.75, and EUR/ITL 1936.27, respectively. Research implications/limitations – After potential Grexit Greek authorities could expect significant nominal depreciation of a new currency (or should introduce it with a substantial discount). In the case of Italexit, the new currency would preserve its nomi- nal value. The limitations of the research methodology are: a long period of the analysis covers structural changes of financial markets, crisis events, political factors (e.g., QE programs). Originality/value/contribution – The originality of this approach lies in the combina- tion of two important economic concepts – the idea of shadow exchange rate and the index of speculative pressure. Combined together they help to prepare the methodology of shadow exchange rates evaluation for currencies that are currently in the common currency system (e.g., currency union). These results can help in economic and political discussions on effects of leaving the currency union. Keywords: nominal exchange rates, euro area, financial crises.

Macroeconomics of the Euro

While it is a long-standing idea in international macroeconomic theory that flexible nominal exchange rates have the potential to facilitate adjustment in international relative prices, a monetary union necessarily forgoes this mechanism for facilitating macroeconomic adjustment among its regions. Twenty years of experience in the eurozone monetary union, including the eurozone crisis, have spurred new macroeconomic research on the costs of giving up nominal exchange rates as a tool of adjustment, and the possibility of alternative policies to promote macroeconomic adjustment. Empirical evidence paints a mixed picture regarding the usefulness of nominal exchange rate flexibility: In many historical settings, flexible nominal exchanges rates tend to create more relative price distortions than they have helped resolve; yet, in some contexts exchange rate devaluations can serve as a useful correction to severe relative price misalignments. Theoretical advances in studying open economy models either support the usefulness of exchange rate movements or find them irrelevant, depending on the specific characteristics of the model economy, including the particular specification of nominal rigidities, international openness in goods markets, and international financial integration. Yet in models that embody certain key aspects of the countries suffering the brunt of the eurozone crisis, such as over-borrowing and persistently high wages, it is found that nominal devaluation can be useful to prevent the type of excessive rise in unemployment observed. This theoretical research also raises alternative polices and mechanisms to substitute for nominal exchange rate adjustment. These policies include the standard fiscal tools of optimal currency area theory but also extend to a broader set of tools including import tariffs, export subsidies, and prudential taxes on capital flows. Certain combinations of these policies, labeled a “fiscal devaluation,” have been found in theory to replicate the effects of a currency devaluation in the context of a monetary union such as the eurozone. These theoretical developments are helpful for understanding the history of experiences in the eurozone, such as the eurozone crisis. They are also helpful for thinking about options for preventing such crises in the future.

Monetary Policy and the Predictability of Nominal Exchange Rates

This article studies how the monetary policy regime affects the relative importance of nominal exchange rates and inflation rates in shaping the response of real exchange rates to shocks. We document two facts about inflation-targeting countries. First, the current real exchange rate predicts future changes in the nominal exchange rate. Second, the real exchange rate is a poor predictor of future inflation rates. We estimate a medium-size, open-economy DSGE model that accounts quantitatively for these facts as well as other empirical properties of real and nominal exchange rates. The key estimated shocks that drive the dynamics of exchange rates and their covariance with inflation are disturbances to the foreign demand for dollar-denominated bonds.
