Inflation Targeting and Exchange Rate Pass-Through: The Turkish Experience

Using a vector autoregression model, we show that the pass-through from imported inflation to domestic inflation has weakened substantially and slowed after the adoption of inflation targeting in Turkey. We argue that this finding is due mainly to several features—such as enhanced credibility of the central bank, changing behavior of the exchange rate, and a shift in expectation formation—possibly acquired by the implementation of a successful inflation-targeting regime. These observations suggest that adopting an inflation-targeting regime in itself may help to reduce exchange rate pass-through.     

Real Exchange Rates and Fundamentals: A Cross‐Country Perspective

This paper employs newly constructed measures for productivity differentials, external imbalances, and commodity terms of trade to estimate a panel cointegrating relationship between real exchange rates and a set of fundamentals for a sample of 48 industrial countries and emerging markets. It finds evidence of a strong positive relation between the consumer price index‐based real exchange rate and commodity terms of trade. The estimated impact of productivity growth differentials between traded and nontraded goods, while statistically significant, is small. Increases in net foreign assets, government consumption, and trade restrictions tend to be associated with appreciating real exchange rates.     

匈牙利汇率制度改革与启示

2001年10月以来匈牙利福林汇率先后实行水平区间盯住和自由浮动制度。通过分析此间货币政策执行情况和汇率走势,发现实行浮动汇率制度有助于通胀目标制在匈牙利的实施,但自由浮动制可能并不是最优的选择,改善经济基本面是防范汇率冲击的根本。这为中国当前的经济发展政策和人民币汇率制度改革提供了借鉴。     

人民币汇率波动与中日贸易

金融危机使人民币汇率存在着较大的不确定性和波动性,对中日贸易产生着重要影响。通过建立中日贸易模型的实证研究,结果表明中国对日出口收入效应较强,从日进口收入效应较弱;对日出口价格效应极强,从日进口价格效应较弱;对日出口汇率波动效应较强,从日进口汇率波动效应不存在。因此,若人民币持续升值,汇率波动日益增强,中国经济将会受到严重冲击。故中国政府应暂缓人民币升值,放缓人民币汇率形成机制改革的步伐。     

House Price Booms,Current Account Deficits,and Low Interest Rates

Domestic factors, such as credit and preference shocks, can explain the negative correlation between house prices and the current account in the U.S. and several other countries before the recent crisis. These shocks, however, cannot account for the fall of world real interest rates observed in the data. Expansionary monetary policy shocks in the U.S., coupled with exchange rate pegs to the dollar in emerging economies, are crucial to understanding the evolution of the real interest rate. Yet, monetary policy factors play virtually no role for house prices and the current account.     

汇率风险与中国出口贸易的动态关系

应用GARCH模型、自回归分布滞后模型和Johansen协整检验,实证分析汇率风险与中国出口贸易的动态关系。结果显示:中国实际有效汇率变动率存在着异方差;实际有效汇率的变动对出口存在较明显的J曲线效应;GARCH模型估计的随时间变动的汇率风险对出口的影响存在着滞后效应;汇率风险在短期内对出口的影响不确定,长期的影响为负。因此,中国在制定出口贸易政策时,应考虑到J曲线效应并保持汇率的稳定性。     

Monetary shocks,exchange rates,and the extensive margin of exports

This paper develops a two-country Dynamic General Equilibrium model to assess the relationship between the real exchange rate and the extensive margin of exports. Exchange rate pass-through to consumer prices governs the relative strength of a demand channel onto the exporting decision of a firm. With incomplete pass-through, a favorable movement in the real exchange rate generates increased export participation and an expansion in the extensive margin of exports. This result is consistent with firm-level studies, and contributes to an ongoing empirical debate as to the importance of changes in export participation over the business cycle.     

Separation of Unit of Account from Medium of Exchange

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity–money system is investigated by considering explicitly a seller's choice of UoA in terms of either an MoE or a unit of metal weight. If the likelihood of debasement of an MoE and its rate are high enough, the price is posted in terms of a unit of metal weight rather than an MoE. Interestingly, this MoE–UoA separated equilibrium yields the flexible nominal price, whereas an MoE–UoA integrated equilibrium yields the sticky one. This implies the nominal price rigidity in the fiat‐money system where MoE and UoA are integrated.     

跨境贸易人民币结算量与货币供应量、汇率波动互动关系

通过构建向量自回归模型（VAR）的方法,对我国跨境贸易人民币结算波动、进出口贸易总额波动、汇率波动之间的动态关系进行研究,试图揭示其三者之间存在的相互关系。研究结果显示：货币供应量波动、汇率波动于跨境贸易人民币结算量波动之间存在长期稳定均衡关系。长期内,汇率波动对跨境贸易人民币结算量波动具有正向促进作用;货币供应量波动对其具有反向促进作用。格兰杰因果关系显示跨境贸易人民币结算量波动是汇率波动的单向Granger原因,同时也是货币供应量波动单向Granger原因;汇率波动在是货币供应量波动的单向Granger原因。脉冲响应函数结果显示：跨境贸易人民币结算量波动对来自其自身冲击的响应在三种变量冲击中最为明显;货币供应量对来自其自身及其他变量的脉冲均有较为明显的响应;汇率对来自其自身冲击的响应在三种变量冲击中最为明显。     

人民币汇率波动对我国与东亚地区双边贸易影响的实证研究

国际金融危机过程中,东亚部分国家和地区货币竞相贬值以促进出口的做法使得国内要求人民币贬值的呼声甚高。实证结果表明,中国与东亚地区收入水平差距、市场经济化程度以及商品价格水平拉大将导致双边贸易收支的扩大,而人民币相对汇率的升值将缩小中国与东亚地区的双边贸易收支。与此同时．人民币汇率波动对中国与东亚地区贸易收支的影响还存在着国别（地区）效应。对于中国而言,在努力扩大出口的同时应兼顾国家发展战略,坚持产业升级、慎用货币贬值措施,并应通过多次、小幅升值的方式保持人民币的强势地位。     

Exchange Rate Pass‐Through,Domestic Competition,and Inflation: Evidence from the 2005–08 Revaluation of the Renminbi

Import competition from China is pervasive in the sense that for many good categories, the competitive environment that U.S. firms face in these markets is strongly driven by the prices of Chinese imports, and so is their pricing decision. This paper quantifies the effect of the government‐controlled appreciation of the Chinese renminbi vis‐à‐vis the USD from 2005 to 2008 on the prices charged by U.S. domestic producers. In a panel spanning the period from 1994 to 2010 and including up to 519 manufacturing sectors, import price changes of Chinese goods pass into U.S. producer prices at an average rate of 0.7, while import price changes that can be traced back to exchange rate movements of other trade partners only have mild effects on U.S. prices. Further analysis points to the importance of trade integration, variable markups, and demand complementarities on the one side, and to the importance of imported intermediate goods on the other side as drivers of these patterns. Simulations incorporating these microeconomic findings reveal that a substantial revaluation of the renminbi would result in a pronounced increase in aggregate U.S. producer price inflation.     

Dealing with Time Inconsistency: Inflation Targeting versus Exchange Rate Targeting

Adopting a single instead of multiple targets can be an effective way to overcome the classic time‐inconsistency problem. The choice of a single mandate depends on the trade openness and the credibility. Reduced‐form empirical results show as central banks become less credible, they are more likely to adopt a pegged exchange rate, and the tendency to peg depends on trade openness. In a model with “loose commitment,” as credibility falls, either an inflation target or a pegged exchange rate is more likely to be adopted. A relatively closed (highly open) economy would adopt an inflation target (exchange rate peg).     

Exchange Rate Policy and Sovereign Bond Spreads in Developing Countries

This paper analyzes how exchange rate policy affects the issuance and pricing of sovereign bonds for developing countries. We find that countries with less flexible exchange rate regimes pay higher spreads and are less likely to issue bonds. Changing a free‐floating regime to a fixed regime decreases the likelihood of bond issuance by 5.5% and increases the spread by 88 basis points on average. Countries with real overvaluation have higher spreads and higher bond issuance probabilities. The effects of real overvaluation on sovereign bonds tend to be magnified for countries with fixed exchange rate regimes.     

Asymmetric Labor Market Institutions in the EMU and the Volatility of Inflation and Unemployment Differentials

How does the asymmetry of labor market institutions affect the adjustment of a currency union to shocks? To answer this question, this paper sets up a dynamic currency union model with monopolistic competition and sticky prices, hiring frictions, and real wage rigidities. In our analysis, we focus on the differentials in inflation and unemployment between countries, as they directly reflect how the currency union responds to shocks. We highlight the following three results. First, we show that it is important to distinguish between different labor market rigidities as they have opposite effects on inflation and unemployment differentials. Second, we find that asymmetries in labor market structures tend to increase the volatility of both inflation and unemployment differentials. Finally, we show that it is important to take into account the interaction between different types of labor market rigidities. Overall, our results suggest that asymmetries in labor market structures worsen the adjustment of a currency union to shocks.     

Asset Prices,News Shocks,and the Trade Balance

We analyze the relationship between asset prices and the trade balance estimating a Bayesian VAR for a broad set of 38 industrialized and emerging market countries. To derive model‐based identifying restrictions, we model asset price shocks as news shocks about future productivity in a two‐country dynamic stochastic general equilibrium model. Such shocks are found to exert sizable effects on the trade balance. Moreover, the effects are highly heterogeneous across countries. For instance, following a news shock that implies on impact a 10% increase in domestic equity prices relative to the rest of the world, the U.S. trade balance will worsen by up to 1.0 percentage points, but much less so for most other economies. We find that this heterogeneity appears to be linked to the financial market depth and equity home bias of countries. Moreover, the channels via wealth effects and via the real exchange rate are important for understanding the heterogeneity in the transmission.     

人民币名义汇率变动对中美贸易收支影响的研究——基于毕肯戴克—罗宾逊—梅茨勒条件视角的实证分析

从毕肯戴克—罗宾逊—梅茨勒条件的视角,同时考虑需求与供给两方面因素对中美贸易差额的影响,采用SPSS线性回归后退法分析中美贸易差额与人民币名义汇率、两国价格水平、国民收入、劳动力成本及储蓄率差额的相关关系,结果表明,中美双边货物贸易中美国的巨额逆差自有其深刻的经济政治原因,人民币升值无助于消除美国的逆差。     

有效汇率、贸易顺差与跨境资本流动的动态关系研究--基于国际收支平衡表的时间序列分析

文章采用1988年1季度到2014年2季度的国际收支平衡表数据,通过建立 VAR模型分析了名义有效汇率、货物贸易顺差与跨境资本流动之间的相互关系。研究结果表明：（1）三者之间存在着一种非对称的互动关系;（2）“货物贸易顺差→名义实际汇率→跨境资本流动→货物贸易顺差”之间形成了自我循环机制,而这一自我循环机制的关键是“货物贸易顺差←→跨境资本流动”互为因果且相互加强的关系;（3）中国双顺差现象是一个结构性问题,并与该自我循环机制密切相关。
