Fiscal Policy and the Terms of Trade in an Analytical Two-Country Dynamic Model

This paper presents a two-country dynamic perfect foresight Ricardian model with wealth effects to study the relationship between government spending financed by alternative taxation, the terms of trade and welfare. An increase in domestic government spending financed by a distortionary capital income tax leads the real exchange rate initially to appreciate (a pure demand effect). But along the transitional path an intertemporal terms of trade effect (a supply side effect) operates and the real exchange rate depreciates to a steady state value ultimately higher relative to the initial equilibrium. The welfare of the domestic resident increases due to a reversed immiserizing growth effect.     

On financial risk and the safe haven characteristics of Swiss franc exchange rates

We analyse bilateral Swiss franc exchange rate returns in an asset pricing framework to evaluate the Swiss franc's safe haven characteristics. A “safe haven” currency is a currency that offers hedging value against global risk, both on average and in particular in crisis episodes. To explore these issues we estimate the relationship between exchange rate returns and risk factors in augmented UIP regressions, using recently developed econometric methods to account for the possibility that the regression coefficients may be changing over time. Our results highlight that in response to increases in global risk the Swiss franc appreciates against typical carry trade investment currencies such as the Australian dollar, but depreciates against the US dollar, the Yen and the British pound. Thus, the Swiss franc exhibits safehaven characteristics against many, but not all other currencies. We find statistically significant time variation in the relationship between Swiss franc returns and risk factors, with this link becoming stronger in times of stress.     

人民币汇率传递的不对称效应

在不同的汇率波动方向及波动幅度下,汇率传递可能是不对称的。利用中国17个主要贸易伙伴1994～2008年年度数据对人民币汇率传递的不对称性实证研究发现,在不同的汇率波动方向下,汇率传递弹性是不同的。人民币汇率贬值时的汇率传递弹性为负,升值时的汇率传递弹性为正。在不同的汇率波动幅度下,汇率传递同样是不对称的。当人民币汇率波动幅度小于2．68％时,汇率传递弹性为-0．5815;当汇率波动幅度大于2．68％时,汇率传递弹性为-0．0578。     

Equity and fixed income markets as drivers of securitised real estate

This paper re-examines the sensitivity and importance of interest rates and stock market price behavior on securitised property by decomposing their long-run impact between transient and permanent effects. This is achieved in a framework that accounts for endogenously determined structural breaks within the data. The results provide a different perspective on the relationship securitised property has with these markets and sheds new light on their long-run interaction. Once structural breaks are accounted for the results show that securitised property is driven by both interest rate and stock market changes, regardless of the type of securitised property being examined. Evidence also points to companies with increased debt-to-asset ratios and companies that are tax-exempt entities are still all influenced by both the equity and fixed income markets over the long-run period, although the influence these factors have do vary across time.     

Why interest rates react to money announcements: An explanation from the foreign exchange market

When the Fed announces a money supply greater than had been expected, interest rates rise. Why? One explanation is that the market raises its estimate of the future rates of money growth and inflation, and bids up nominal interest rates. We offer contrary evidence: on such days the dollar appreciates, not depreciates. An alternative explanation is that the market perceives the change in the money stock as a transitory fluctuation that the Fed will reverse in the future. The anticipated future tightening raises today's real interest rate, causes a capital inflow, and appreciates the dollar, the result in fact observed.     

Step Interventions and Market Integration: Tests in the U.S., U.K., and Australian Property Markets

Market integration implies the existence of some long-run equilibrium relationship between markets such that movements in one market are transmitted to movements in another. It is an interesting observation of much of the literature regarding a possible relationship between real estate and stock markets that there is relatively scant attention given to the possible existence of structural breaks and the impact that such breaks may have on tests for market integration. Other research has shown that failure to take into account structural breaks in various macroeconomic data series may have yielded misleading results on cointegration (in particular, unit root tests on individual series). In this article we examine the issue of whether the stock market and real estate markets are stationary or nonstationary in the presence of structural breaks. We adopt the techniques of Perron (1989), Zivot and Andrews (1992), and Perron and Vogelsang (1992). Each of these tests is based on different assumptions and therefore may yield differing results. In general, the results do not support cointegration of domestic property and equity markets or cointegration of markets internationally.     

U.S. presidential cycles and the foreign exchange market

We examine the association between the foreign exchange rate of the US dollar and US presidential cycles. Results show that Republican presidencies tend to start with a strong dollar, which then depreciates over the course of the presidency. In contrast, Democratic presidencies tend to begin with a weak dollar that then appreciates. These patterns result in an apparent presidential effect in US foreign exchange rates, the direction of which depends on whether exchange rates are measured by levels or by returns.     

Consumption,government spending,and the real exchange rate

Using panel structural VAR analysis and quarterly data from four industrialized countries, we document that an increase in government purchases raises output and private consumption, deteriorates the trade balance, and depreciates the real exchange rate. This pattern of comovement poses a puzzle for both neoclassical and Keynesian models. An explanation based on the deep-habit mechanism is proposed. An estimated two-country model with deep-habits is shown to replicate well the observed responses of output, consumption, and the trade balance, and the initial response of the real exchange rate to an estimated government spending shock.     

Foreign Exchange Fixings and Returns around the Clock

The U.S. dollar appreciates in the run-up to foreign exchange (FX) fixes and depreciates thereafter, tracing a W-shaped return pattern around the clock. Return reversals for the top nine traded currencies over a 21-year period are pervasive and highly statistically significant, and they imply daily swings of more than one billion U.S. dollars based on spot volumes. Using natural experiments, we document the existence of a published reference rate determines the timing of intraday return reversals. We present evidence consistent with an inventory risk explanation whereby FX dealers intermediate unconditional demand for U.S. dollars at the fixes.     

Purchasing power parity in ASEAN-5 countries: revisit with cross-sectional dependence and structural breaks

This paper re-examines the purchasing power parity (PPP) hypothesis for a panel of ASEAN-5 countries. The panel unit root and cointegration tests, which incorporate cross-sectional dependence and multiple structural breaks, are innovatively used for testing the PPP hypothesis. We could not find evidence that supports the existence of a long-run equilibrium between the relative price ratio and the nominal exchange rate for the whole period. Nevertheless, there is evidence of a cointegrating relationship for the post-crisis period. Our finding implies that a flexible exchange rate regime is suitable for the individual ASEAN countries.     

贸易摩擦、宏观经济波动与经济开放程度的选择

本文构建一个包含关税冲击以及外汇风险溢价的两国开放经济DSGE模型,创新地揭示了关税冲击造成实际汇率波动的“直接效应”与“间接效应”,刻画了关税变动、贸易条件与实际汇率之间的动态关系与作用机制。我们深入分析了不同经济开放程度下贸易摩擦造成的宏观经济波动以及经济福利损失。模拟结果表明,在一定贸易开放程度下,外国加收关税一方面会导致本国贸易条件恶化,引发出口及产出下降;另一方面会导致本国汇率贬值,引发出口及产出增长。关税冲击发生后短期中汇率贬值效应占优,本国产出会出现小幅上升,随后贸易条件恶化效应逐步显现,产出持续下降。福利分析结果表明,本国适度提升贸易开放度,虽然经济福利损失会小幅上升,但福利损失增加幅度小于外国,会在贸易摩擦竞争中形成相对优势;如果本国过度提高贸易开放度,则会导致本国福利损失大幅增加,并且大于外国福利损失增幅,会在贸易摩擦竞争中形成相对劣势。因此,应适度逐步有序地提升贸易开放度。此外,本国适度推进资本账户开放的政策能够改善贸易条件,促进本国经济增长。

Nonlinear equilibrium adjustment dynamics and predictability of the term structure of interest rates

We analyze money market dynamics under a long-run equilibrium framework where commonly-monitored spreads serve as error correction terms, derived from a structural model incorporating autocorrelated risk premia, interest rate smoothing and monetary policy feedback. Using a dataset of monthly observations of the spot next and four-, thirteen-, twenty six- and fifty two-week Treasury Bills rates for the United States, Germany and United Kingdom from January 1999 to April 2016, we investigate the power of the expectations hypothesis theory of interest rates taking into account long-run deviations from equilibrium and inherent nonlinearities. We reveal short-run dynamic adjustments for the term structure of the USA, Germany and the UK, which are subject to regime switches. When forecastability is tested during May 2016–October 2017, the MSIH-VECM outperforms systematically the VECM. This is the first attempt to explore the possibility of parameter instability as a crucial factor in deriving the rejection of the restricted version of the cointegration space. Moreover, we investigate the dynamic out-of-sample forecasts of the term structure to assess the effectiveness of nonlinear MS-VECM modeling in capturing the after-effects of the global crisis. Overall, our results suggest that regime shifts in the mean and variance of the term structure may be intertwined with changes in fundamentals, that play a role in driving interest rate regimes, in particular business cycle and inflation fluctuations.     

Capital accumulation and international trade

Capital accumulation is introduced into a version of Eaton–Kortum model of international trade, imposing period by period balanced trade. The effects of tariff changes on world steady states and transition dynamics are studied. A calibrated version of the model is used to assess the short- and long-run gains from a world-wide elimination of trade tariffs. The determinants and importance of convergence in world-wide capital as well as convergence on the relative capitals and incomes are analyzed. Positive and normative comparisons with an analogous static model are conducted, as well as comparisons steady state welfare comparisons vs full dynamic gains.     

How do the Renminbi and other East Asian currencies co-move?

This paper investigates the degree and the nature of exchange rate co-movements between the Renminbi and a set of seven East Asian currencies by estimating Markov switching models with regime-dependent correlations and time-varying transition probabilities. These models have several advantages. First, exchange rate co-movements can vary across different depreciation and appreciation regimes. Second, the Renminbi can act as a transition variable that provides information regarding how the exchange rates evolve over time. After controlling for global effects and exchange market pressures, the results yield robust evidence of the Renminbi’s rising role in East Asia as a significant factor in currency fluctuations. A key result is that regional currencies tend to overreact when the Renminbi depreciates and underreact when it appreciates, suggesting that East Asian economies are not willing to allow their currency to substantially appreciate against the Chinese currency.     

Does leaning against the wind improve exchange-rate performance?

This paper develops a model in which real disturbances cause the exchange rate to overshoot its new long-run equilibrium level because of speculative risk aversion combined with the well-known lagged effect of the exchange rate on trade flows. In this context, it is demonstrated that there exists an optimal degree of leaning against the wind, which stabilizes the exchange rate at the new equilibrium, but which requires the government to have accurate information about the exchange rate-trade flow lag. Without this information, leaning against the wind may increase the deviations of the exchange rate from its long-run level.     

Trend breaks, long-run restrictions, and contractionary technology improvements

Structural vector autoregressions with long-run restrictions are extraordinarily sensitive to low-frequency correlations. Recent literature finds that the estimated effects of technology shocks are sensitive to how one treats hours per capita. However, after allowing for (statistically and economically significant) trend breaks in productivity, results are much less sensitive: hours fall when technology improves. The issue is that the common high-low-high pattern of productivity growth and hours (i.e., the low-frequency correlation) inevitably leads to a positive estimated response. The trend breaks control for this correlation. This example suggests a practical need for care in using long-run restrictions.     

Real exchange rates and skills

Recent developments in trade theory strongly emphasize that international trade requires an intensive use of skilled workers. Against this background, we explore in this paper whether labor skills are a key determinant of real exchange rates in the long run. Using panel regressions covering 22 countries over the period 1950–2010, we find that labor skills are indeed a structural determinant of real exchange rates, with a permanent increase of the skilled–unskilled labor ratio leading to a long-run appreciation of the real exchange rate. This finding is robust to the inclusion of several control variables, like those used in traditional analyses of real exchange rates.     

Commodity volatility breaks

Volatility is a key determinant of derivative prices and optimal hedge ratios. This paper examines whether there are structural breaks in commodity spot return volatility using an iterative cumulative sum of squares procedure and then uses GARCH (1,1) to model volatility during each regime.The main empirical finding is the very limited evidence of commodity volatility breaks during the recent financial crisis. This suggests commodity return volatility was not exceptionally high during the recent financial crisis compared to the 1985–2010 sample period as a whole. For many commodities there are multiple idiosyncratic breaks in volatility; this suggests commodity specific supply or demand factors are important determinants of volatility. The empirical results overall are consistent with the view that commodities are too diverse to be considered as an asset class. Finally, we find commodity volatility persistence remains very high for many commodity returns even after structural breaks are accounted for.     

Equilibrium exchange rate determination and multiple structural changes

The large appreciation and depreciation of the US Dollar in the 1980s stimulated an important debate on the usefulness of unit root tests in the presence of structural breaks. In this paper, we propose a simple model to describe the evolution of the real exchange rate. We then propose a more general smooth transition (STR) function than has hitherto been employed, which is able to capture structural changes along the (long-run) equilibrium path, and show that this is consistent with our economic model. Our framework allows for a gradual adjustment between regimes and allows for under- and/or over-valued exchange rate adjustments. Using monthly and quarterly data for up to twenty OECD countries, we apply our methodology to investigate the univariate time series properties of CPI-based real exchange rates with both the U.S. Dollar and German Mark as the numeraire currencies. The empirical results show that, for more than half of the quarterly series, the evidence in favor of the stationarity of the real exchange rate was clearer in the sub-sample period post-1980.
