Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

Long-run determinants of the Irish real exchange rate

Smooth adjustment to real exchange rate shifts is one of the major challenges facing the Irish economy under EMU. Rather than assume purchasing power parity, the long-run real exchange rate is modelled as time-varying, being determined by relative output levels, the terms of trade and the net foreign asset position. It is shown that these factors account for a large proportion of the long-run movement in the Irish real exchange rate.     

The U.S. trade imbalance and real exchange rate: An application of the heterogeneous panel cointegration method

The United States economy suffers from persistent trade deficits, arising from the so-called ‘global external imbalance’. Can the depreciation of the US dollar improve this phenomenon? This study for the first time applies the heterogeneous panel cointegration method to examine the long-run relationship between the real exchange rate and bilateral trade balance of the U.S. and her 97 trading partners for the period 1973–2006. Using new annual data, the empirical results indicate that the devaluation of the US dollar deteriorates her bilateral trade balance with 13 trading partners, but improves it with 37 trading partners, especially for China. In the panel cointegrated framework, a long-run negative relationship between the real exchange rate and the bilateral trade balance exists for the U.S.     

Limited asset market participation and the consumption‐real exchange rate anomaly

Abstract Under efficient consumption risk sharing, as assumed in standard international business cycle models, a country's aggregate consumption rises relative to foreign consumption, when the country's real exchange rate depreciates. Yet empirically, relative consumption and the real exchange rate are essentially uncorrelated. This paper shows that this ‘consumption‐real exchange rate anomaly’ can be explained by a simple model in which a subset of households trade in complete financial markets, while the remaining households lead hand‐to‐mouth (HTM) lives. HTM behaviour also generates greater volatility of the real exchange rate and of net exports, which likewise brings the model closer to the data.     

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。     

Terms‐of‐Trade Shocks and Exchange Rate Regimes in a Small Open Economy*

We examine the impact of terms‐of‐trade shocks on key macroeconomic variables by numerically solving a dynamic stochastic general equilibrium model of a small open economy. The model considers nominal price rigidity under different exchange rate regimes. The numerical solutions obtained are consistent with the empirical regularities documented by Broda (2004), in which output responses to shocks are smoother in floats than in pegs; in moving from pegs to floats, the rise in nominal exchange rate volatility is coupled by the rise in real exchange rate volatility; and in both exchange rate regimes, net foreign assets is the most volatile variable.     

Asset prices, exchange rates and the current account

This paper analyses the role of asset prices in comparison to other factors, in particular exchange rates, as a driver of the US trade balance. It employs a Bayesian structural VAR model that requires imposing only a minimum of economically meaningful sign restrictions. We find that equity market shocks and housing price shocks have been major determinants of the US current account in the past, accounting for up to 30% of the movements of the US trade balance at a horizon of 20 quarters. By contrast, shocks to the real exchange rate have been less relevant, explaining about 9% and exerting a more temporary effect on the US trade balance. Our findings suggest that large exchange rate movements may not necessarily be the key element of an adjustment of today's large current account imbalances, and that in particular relative global asset price changes could be a potent source of adjustment.     

Sudden stops,sectoral reallocations,and the real exchange rate

A sudden stop of capital flows into a developing country tends to be followed by a rapid switch from trade deficits to surpluses, a depreciation of the real exchange rate, and decreases in output and total factor productivity. Substantial reallocation takes place from the nontraded sector to the traded sector. We construct a multisector growth model, calibrate it to the Mexican economy, and use it to analyze Mexico's 1994–95 crisis. When subjected to a sudden stop, the model accounts for the trade balance reversal and the real exchange rate depreciation, but it cannot account for the decreases in GDP and TFP. Extending the model to include labor frictions and variable capital utilization, we still find that it cannot quantitatively account for the dynamics of output and productivity without losing the ability to account for the movements of other variables.     

Growth in a time of external imbalances

Globalization and financial integration have increased in the last three decades giving rise to cumulated large external imbalances. The question we address in this paper is whether economic growth can be affected by these external imbalances. We estimate an augmented growth equation with the external stock position of the countries measured by the net foreign asset position. Unlike previous literature, we use non-parametric methods that capture non-linearities and heterogeneity, and apply them to a sample that includes 106 developed and developing countries for the period 1983-2011. Contrary to the neoclassical theory, we find that improvements in the external position foster growth. Our results are in line with current theoretical contributions explaining the Lucas Paradox where financial frictions are present. Within this framework, the general outcome should be a positive sign and the “neoclassical” negative relationship between net foreign assets and growth would be just a particular case, with no universal explanatory mechanism. Accordingly, we find that the effect of the net foreign asset position on growth is heterogeneous, the impact depending on the characteristics of the countries such as institutional quality, openness and financial development.     

The Malaysian Real Trade Balance and the Real Exchange Rate

The cointegration technique is used to examine the long‐run and short‐run relationships between the real Malaysian trade balance with the real exchange rate, domestic and world incomes. The results suggest that a real ringgit exchange rate depreciation improves the trade balance in the long run. World and domestic incomes are also found to be important determinants of trade balance. The significance of world income on trade balance indicates that Malaysia is prone to external shocks. An error‐correction model is then estimated to study the short‐run dynamics of the effects of exchange rate. The impulse response analysis shows that the effect of exchange rate on the trade balance lasts for about three years. A devaluation of ringgit will initially improve the trade balance, albeit small, after which the trade balance starts to deteriorate, and then improves again suggesting that there exists a delayed J‐curve.     

Fundamentals at Odds? The US Current Account Deficit and Dollar

In mid‐2008, the real effective exchange rate (REER) of the dollar was close to its minimum level for the past four decades. At the same time, however, the US trade and current account deficits remain large and, absent a significant correction in coming years, would contribute to a further accumulation of US external liabilities. The paper discusses the tension between these two aspects of the dollar assessment, and what factors can help to reconcile them. It focuses in particular on the terms of trade, adjustment lags and measurement issues related to both the REER and the current account balance.     

The real exchange rate and economic development

Recent empirical studies have found a robust correlation between competitive exchange rates and economic growth in developing economies. This paper presents (i) a formal model to help explain these findings and (ii) econometric evidence on the relation between investment and the real exchange rate. The model emphasizes the existence of (hidden) unemployment as a source of endogenous growth, even under constant returns to scale. Growth promoting policies, however, affect the external balance, and two instruments are needed in order to achieve targets for both the growth rate and the trade balance. The real exchange rate can serve as one of those instruments. The implications of the model for the relation between real exchange rates and the rate of capital accumulation find support in our econometric analysis.     

On the Complementarity of Equilibrium Exchange‐Rate Approaches

Based on a simple, stock–flow adjustment framework, we show that existing concepts of equilibrium exchange rates can be viewed as realizations of the same model at different time horizons. We then compare fundamental and behavioral estimations of equilibrium exchange rates based on the same, econometric modeling of the net foreign asset position in the long run, for a panel of 15 countries over the 1980–2005 period. These estimations suggest that, although more robust to alternative assumptions, the BEER approach may rely on excessive confidence on past behaviors in terms of portfolio choices. Symmetrically, FEERs may underestimate the plasticity of international capital markets because they focus on the adjustment of the trade balance.     

Portfolio allocation and international risk sharing

Abstract We show that recent explanations of the consumption‐real exchange rate anomaly that rely on goods and financial market frictions are not robust to introducing just one additional international asset. When portfolios are selected optimally, international trade in two nominal bonds implies a consumption‐real exchange rate correlation that is too high compared with the data even when there are many shocks. Monetary policy specification plays a potentially important role for the degree of risk sharing provided by nominal bonds, both in the benchmark model with only tradable and non‐tradable sector supply shocks and also in the model that allows for news.     

Currency Exposure to Downside Risk: Which Fundamentals Matter?

I study whether or not countries' macroeconomic characteristics are systematically related to their currencies' exposure to the downside market risk. I find that the currency downside risk is strongly associated with the local inflation rate, real interest rate and net foreign asset position. Currencies of countries with high inflation and real interest rates and negative net foreign asset position (debtor countries) are more exposed to the downside risk whereas currencies of countries with low inflation and real interest rates and positive net foreign asset position (creditor countries) exhibit “safe haven” properties. The local real interest rate has the highest explanatory power in accounting for the cross‐section of currency exposure to the downside risk. This suggests that the high currency exposure to the downside risk is a consequence of investments in high‐yield risky countries and flight from them in “hard times”.     

Nontradable sector reform and external rebalancing in monetary union: A model-based analysis

The paper uses the QUEST III model to analyse the question of whether nontradable (service) sector reform would reduce external imbalances in monetary union, notably from the side of surplus countries. It considers an open economy with a positive net foreign asset (net creditor) position and shows that tradable and nontradable sector reforms, understood as reforms that shift the supply curve in the respective sector outward, tend to have similar external balance effects. Namely, supply-side reforms improve the price competitiveness of domestic output and tend to increase the trade and current account balance on impact. In the longer term, competitiveness gains are compensated by additional imports associated with domestic income growth. Starting from a non-zero NFA position, the denominator effect does also contribute significantly to changes in external accounts relative to GDP. The results are robust across modifications of the model.     

The effects of government spending shocks on the real exchange rate and trade balance in Turkey

The aim of this study is to investigate the effects of government spending shocks on the real exchange rate and foreign trade balance in Turkey for the period of 2002:01–2012:04 within a structural VAR framework. The analysis shows that a positive shock to the government spending tends to induce real exchange rate appreciation and deterioration in trade balance. We also find that the composition of the government spending matters. Although shocks to the government nonwage consumption generate an appreciation in the real exchange rate and worsening of the trade balance, the effects of government investment shocks remain insignificant. Furthermore, the analysis demonstrates that shocks to government spending are associated with a rise in taxes, which is indicative of a spending-driven tax adjustment process in Turkey.     

Trade Balance and Exchange Rate: Unit Roots, Co-integration and Long Memory in the US and the UK

This paper deals with the relationship between the balance of trade and the exchange rate in the US/UK case. Many authors have studied this issue for many countries, but despite the intensive research, there is still no agreement about the effectiveness of currency devaluation to increase a country's balance of trade. We first analyse the relationship between the two variables using unit roots and co-integration methods, and the results are ambiguous. We try a new approach based on fractional integration. The unit root hypothesis is rejected in case of the trade balance in favour of smaller orders of integration, while this hypothesis is not rejected for the exchange rate. Thus, the two series do not possess the same order of integration. We sort this problem out by taking the exchange rate as an exogenous variable, and including it in a regression model where the residuals might follow a fractionally integrated model.     

Forward Rates,Interest Rates,and Expectations Under Alternative Exchange Rate Regimes*

A model comprising spot and forward foreign exchange markets and a domestic credit market is used to examine the trade-off between volatility in the nominal exchange rate and domestic interest rate. It also shows how a slowly crawling spot rate can raise interest rate volatility and the amplitude of reserve flows. Finally, the paper extends a finding by Driskill and McCafferty that the exchange rate effects of external shocks are differently affected by the responsiveness of speculation to expected profits; high responsiveness makes the spot exchange rate more sensitive to foreign financial shocks but less sensitive to trade balance shocks.     

The J‐Curve: Evidence from Fiji*

This article provides new evidence on both long run and short‐run determinants of trade balance for Fiji and investigates evidence of J‐curve adjustment behaviour in the aftermath of a devaluation. We adopt a partial reduced form model that models the real trade balance directly as a function of the real exchange rate and real domestic and foreign incomes. Cointegration analysis is based on a recently developed autoregressive distributed lag approach—shown to provide robust results in finite samples. The long run elasticities are also estimated using a dynamic ordinary least squares approach and the Fully Modified Ordinary Least Squares (FM‐OLS) approach. Amongst our key results we find that there is a long‐run relationship between trade balance and its determinants. There is evidence of the J‐curve pattern; growth in domestic income affects Fiji’s trade balance adversely while foreign income improves it.
