Dynamic Links Between Unexpected Exchange Rate Variation, Prices, and International Trade

This paper investigates dynamic interrelations between exchange rate uncertainty, international trade, and trading competitiveness in prices, using UK data. The empirical results derived from vector autoregressive (VAR) models show that a shock to exchange rate volatility negatively affects trade volumes, and such negative effects are greater than the effects on trade price levels.

Does Real Exchange Rate Volatility Affect Sectoral Trade Flows?

This article investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the United States and its top 13 trading partners. Our investigation also considers those effects on trade flows that may arise through changes in income volatility and the interaction between income and exchange rate volatilities. We provide evidence that (i) exchange rate volatility does not systematically affect sectoral trade flows, (ii) income volatility has little impact on trade flows, and (iii) the effect of the interaction term on trade flows is opposite that of exchange rate volatility, dampening its impact on trade flows.     

Robust Taylor rules under heterogeneity in currency trade

It is demonstrated in this paper that the exchange rate should be included in the Taylor rule when there is heterogeneity in currency trade to have a determinate and least squares learnable rational expectations equilibrium that also is desirable in an inflation rate targeting regime. Moreover, for certain Taylor rule parameterizations, these properties of the interest rate rule are robust against the degree of technical trading in currency trading.     

Information arrival,interest rate differentials,and yen/dollar exchange rate

This paper examines the effects of interest rate differentials as inflowing information into the forex market on the yen/dollar exchange rate and unexpected trading volume by a structural VAR model. The impulse responses show that the short-term interest rate differential affects the exchange rate through (a) UIP with little change in unexpected trading volume, and (b) different expectation revisions at different points in time with a high transaction volume. The effects of long-term interest rate differential on the exchange rate appear instantaneous with high trading volume, reflecting instantaneous reshuffling in international portfolio holdings of long-term assets.     

人民币实际有效汇率的构建方法研究

当今外汇市场上每天用于贸易交易的外汇交易量不到5％,95％以上都是与贸易交易无关的虚拟资本流动。但迄今为止,理论界和实务部门仍主要从贸易角度入手构建人民币实际有效汇率。本研究从国际收支即同时从经常帐户和资本与金融帐户角度考虑人民币实际有效汇率的形成机制,将相对生产率进步指标纳入人民币实际有效汇率权重的构成中,既吸收了篮子货币的优点,又能减轻由于非汇率对实体经济的冲击造成汇率的较大波动,从而保持一个较稳定的人民币实际有效汇率。论文的模型比IMF的模型更符合当代汇率的形成机制,论文预测了2009和2010年人民币实际有效汇率分别较上一年升值1．36％和1．17％。     

What Enhances Insider Trading Profitability?

This study analyses the factors triggering insider trading profitability. Since there is not much evidence on this topic in the continental-European context, we focus on the Spanish stock market. Our findings show that the main relevant factors (the timing ability of the insider, the transparency of the transaction and the level of free cash flow of the firm) are related to insiders’ opportunities behaviour, motivated by the lack of either managerial control within the firm or enforcement of insider trading regulation. The level of ownership concentration, the spread and the interaction between the size and the transparency of the transaction are other relevant factors, some of them tested for the first time in the insider trading literature.      

Secrecy of Bank of Japan’s Yen intervention: Evidence of efficacy from intra-daily data

This paper examines the intraday effectiveness of the Bank of Japan (BOJ)’s foreign exchange interventions over the period May 13, 1991–March 16, 2004. The existing literature has generally failed to provide a comprehensive study on the effects of the BOJ’s interventions, and particularly, the efficacy of public and secret operations. By dividing a 24-h trading day into three horizons, we show that the intraday evidence on the effects of official interventions documented in prior studies primarily came from publicly known interventions. In the case of secret interventions, although there were no clear impacts on the first moment of exchange rate returns, we found significant second moment responses. Specifically, covert operations were able to reduce the Yen/USD return volatility during both Tokyo and subsequent overnight market hours. Furthermore, our extended model on secret interventions reveals that when the BOJ completely concealed its transactions, undetected interventions were shown to be most effective in both reversing undesired trends and reducing excess return volatilities. On the other hand, those interventions that were rumoured were not as effective. Finally, the interventions conducted during the periods of ‘oral interventions’ were in general more effective in moving the exchange rate in the desired direction.     

The Post‐Mao economic reform in China: A Korean view

Abstract

Previous studies that were concerned with the impact of depreciation of the ringgit on the Malaysian trade balance employed data either between Malaysia and rest of the world or between Malaysia and each of her major trading partners. Specifically, the bilateral trade balance between Malaysia and the US is shown to be insensitive to the real bilateral ringgit–dollar rate. In this article we wonder if disaggregating trade flows between Malaysia and the US by commodity could help us to discover any significant effects that the real exchange rate could have. We consider 101 industries that export from US to Malaysia and 17 industries that import from Malaysia. While majority of the industries showed short-run sensitivity to the real bilateral exchange rate, short-run effects lasted into the long run almost in half of the industries in both group.     

The foreign exchange exposure of Chinese banks

Using the capital market approach and the equity price data of 14 listed Chinese banks, this empirical study finds that there is a positive relationship between bank size and foreign exchange exposure. This relationship may reflect the larger foreign exchange operations and trading positions of larger Chinese banks and their significant indirect foreign exchange exposure arising from impacts of the renminbi exchange rate movements on their customers. Empirical evidence also suggests that the average foreign exchange exposures of state-owned and joint-stock commercial banks in China are higher than those of banks in Hong Kong, notwithstanding their limited participation in international banking businesses compared with their Hong Kong counterparts. It is also found that negative foreign exchange exposure is prevalent for larger Chinese banks, suggesting that an appreciation of the renminbi tends to reduce their equity value. It is therefore likely that the banking sector's performance will be hampered. Together with the fact that decreases in equity values generally imply a higher default risk, the effects of different scenarios of renminbi appreciation on the default risk of Chinese banks should therefore be closely monitored.     

Exchange rate volatility and ASEAN-4’s trade flows: is there a third country effect?

This paper investigates the impact of exchange rate volatility on the trade flows among ASEAN-4 countries (Indonesia, Malaysia, Singapore and Thailand) as well as to their five main trading partners. External volatility is included in the models to study the ‘third country’ effect on the trade flows. We employ annual import and export data over the period of 1980–2012. The results from the bounds testing approach to cointegration and error-correction model reveal that the real exchange rate volatility does play a significant role in 15 export and four import models in short-run and long-run. Moreover, in both import and export models, the effects of exchange rate volatility on trade flows are negative rather than positive. Finally, the effects of volatility from the ASEAN-4’s currency/yuan rate dominate the third country effect on the ASEAN-4’s trade.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.     

电子指令驱动市场上的交易持续期与知情交易的相互关系研究

微观结构文献和实证模型对于交易强度（交易持续期的倒数）与知情交易之间的关系的预测是相互矛盾的。本文试图建立一个研究该问题的实证框架，并采用上海股票市场交易数据进行实证研究。本文的主要发现是：（1）基于利好消息的交易通常会使交易强度增大，而基于利空消息的交易通常会导致较长的交易持续期；（2）较长的持续期会导致价格下跌和较低的波动率；（3）在较低频率数据（如日数据、周数据或月数据）中普遍存在的杠杆效应在本文采用的交易数据中被拒绝。     

Impacts of Foreign Exchange Auctions on the Informal Market Rate in Myanmar

Since the abolition of the official peg and the introduction of a managed float in April 2012, the Central Bank of Myanmar has operated the daily auctions of foreign exchange aimed at smoothing exchange rate fluctuations. Despite the reforms, however, informal trading of foreign exchange remains pervasive. Using the daily informal exchange rate and Central Bank auction data, this study examines the impacts of auctions on the informal rate. Generalized autoregressive conditional heteroskedasticity models indicate that the auctions did not reduce the conditional variance of the informal rate returns. Overall, the auctions have only a quite modest impact on the informal exchange rate.     

人民币汇率与中国贸易平衡:基于汇改后数据的实证研究

Addressing International Empirical Puzzles: the Liquidity of Bonds

Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data.     

Fundamentals and Technical Trading: Behavior of Exchange Rates in the CEECs

We incorporate technical trading into the monetary approach to exchange rates, and estimate the model for four Central and Eastern European countries that introduced the policy of free floating in the late 1990s; the Czech Republic, Hungary, Poland and Slovakia. We find that past exchange rates contribute significantly to the determination of the spot exchange rate. We also find a feedback behavior driving the exchange rate to its fundamental value although the mean reversion parameter is small. Overall, this means that these currency markets have developed a complex structure of different trader types, which already is documented for developed countries.     

Short-run and long-run effects of exchange rate change on trade balance: Evidence from China and its trading partners

As one of largest exporting countries in the world, China has experienced a large amount of trade surpluses for the past decade. However, a growing criticism has been focused on the manipulation of Chinese Yuan (RMB) exchange rate by the Chinese government. While China implemented the exchange rate reform policy in July 2005, the question, whether its currency is undervalued remains as a debatable issue. Different from previous studies by focusing on individual trading partners, this paper tests the short-run J-Curve hypothesis and long-run trade balance effect of real exchange rate between China and its eighteen major trading partners using a panel dataset over the 2005–2009 period. We adopt the methodologies of panel cointegration test, fully modified OLS for heterogeneous cointegrated panel (panel FMOLS) and panel error correction model (panel ECM) to investigate the above examination. Our empirical results lend support to the inverted J-curve hypothesis between China and its trading partners. However, we find that a real appreciation of RMB has a decreasing long-run effect on China's trade balance in only three of the eighteen trading partners, while it has an increasing long-run effect in five of the eighteen trading partners. These mixed findings, therefore, lead to the empirical evidence that the real appreciation of RMB has no overall long-run impact on China's trade balance.

Voluntary Disclosure and Informed Trading*

This study analyzes the impact of informed trading on voluntary corporate disclosure in the presence of two factors: the cost of disclosure and the value of a manager's informedness. In the absence of both factors, informed trading has no impact on disclosure even when traders are not certain whether the manager has information. When disclosure is costly, informed trading serves as a free substitute for the disclosure of favorable information, and reduces disclosure. Surprisingly, when the manager's informedness is valuable for the firm, informed trading can also increase disclosure. Traders can discover unfavorable information about the firm, so managers with such information have less incentive to pool with uninformed managers and disclose to show that they are informed. The study also demonstrates that informed trading can have either a positive or a negative effect on firm value by crowding in or crowding out information production in the firm. These results hold for general information structures and are robust if traders can choose how much information can be acquired.     

A Quantitative Assessment of the Role of Incomplete Asset Markets on the Dynamics of the Real Exchange Rate

I develop a two-country New Keynesian model with capital accumulation and incomplete international asset markets that provides novel insights on the effect that imperfect international risk-sharing has on international business cycles and RER dynamics. I find that business cycles appear similar whether international asset markets are complete or not when driven by a combination of non-persistent monetary shocks and persistent productivity (TFP) shocks. In turn, international asset market incompleteness has sizeable effects if (persistent) investment-specific technology (IST) shocks are a main driver of business cycles. I also show that the model with incomplete international asset markets can approximate the RER volatility and persistence observed in the data, for instance, if IST shocks are near-unit-root. Hence, I conclude that the nature of shocks, the extent of financial integration across countries and the existing limitations on asset trading are central to understand the dynamics of the real exchange rate and the endogenous international transmission over the business cycles.
