The equilibrium pricing of exchange rates and assets when trade takes time

When trade takes time, there are systematic deviations of the exchange rate from its Law of One Price value; these depend on the real interest rate in terms of the importable good. There is no systematic tendency for the spot rate to attain its LOP value in the long run. This means that agents in different countries price the same cash flows by using different risk premia, with agents in the ‘foreign’ country pricing the asset by adding a risk premium related to foreign exchange risk.     

Do foreign banks increase competition? Evidence from emerging Asian and Latin American banking markets

In this paper we examine the impact of foreign bank penetration on the competitive structure of domestic banking sectors in host emerging economies. We focus our analysis on Asia and Latin America during the period 1997-2008. Using bank-level panel data to identify foreign banks and to estimate measures of banking competition, we are able to provide robust empirical evidence that an increase in foreign bank penetration enhances competition in these host countries’ banking sectors. We find that this positive foreign bank penetration and banking competition link is associated with a spillover effect from foreign banks to their domestic counterparts. This spillover effect becomes stronger when more efficient and less risky foreign banks enter into less concentrated host country markets. We also find that the spillover effect is greater when foreign banks enter in the form of ‘de novo penetration’ than through mergers or acquisitions of domestic banks (‘M&A penetration’).     

人民币汇率传递机制研究与启示

汇率传递是指汇率波动通过直接或间接的渠道影响国内价格，影响汇率传递的因素主要包括外贸依存度、市场竞争和市场创新等方面。我国汇率传递效应受市场不完全竞争的影响，其汇率传递效应亦不完全。可以通过企业加速产品结构调整和技术创新，适应汇率弹性增强的需要；加快产业升级与结构调整；并继续实行富有弹性的汇率制度。     

资本高度流动时代的发展中国家最优国际储备──兼评中国外汇储备政策

20世纪90年代以来,发展中国家国际储备管理实践使主流最优国际储备研究思路面临根本性冲击。本文提出,在资本高度流动时代,发展中国家国际储备管理的核心目标是:通过保持“适度”国际储备来稳定国际投机资本,并以此促进汇率稳定。从这一分析思路出发,笔者对中国外汇储备管理有如下看法:有迹象表明,中国目前外汇储备水平已对汇率稳定构成了干扰;从动态发展的视角看,中国实体经济需求不足矛盾和脆弱银行体系面临的严峻竞争,都将扩充中国对外汇储备继续增长的包容性。     

What lies beneath: Foreign exchange rate exposure,hedging and cash flows

This paper presents results from an in-depth analysis of the foreign exchange rate exposure of a large nonfinancial firm based on proprietary internal data including cash flows, derivatives and foreign currency debt, as well as external capital market data. While the operations of the multinational firm have significant exposure to foreign exchange rate risk due to foreign currency-based activities and international competition, corporate hedging mitigates this gross exposure. The analysis illustrates that the insignificance of foreign exchange rate exposures of comprehensive performance measures such as total cash flow can be explained by hedging at the firm level. Thus, the residual net exposure is economically and statistically small, even if the operating cash flows of the firm are significantly exposed to exchange rate risk. The results of the paper suggest that managers of nonfinancial firms with operations exposed to foreign exchange rate risk take savvy actions to reduce exposure to a level too low to allow its detection empirically.     

Time-varying risk attitude and the foreign exchange market behavior

This paper presents a heterogeneous agents model of the foreign exchange market in which agents’ risk attitudes vary over time due to psychological factors emphasized in prospect theory. We find that psychological component and risk-profit elasticity play significant roles in exchange rate expectations formation and investment behavior. Although all agents show more risk-averse after the crisis, the extent to which their risk attitude responds to the crisis varies due to heterogeneous forecasting rules as well as the changes of trading environment and central bank intervention. Moreover, time-varying risk attitudes can help explain the forward premium puzzle. These findings have implications for the exchange rate expectation formation theories and foreign exchange market stability policies.

Taiwan's Foreign Exchange Market—Volatile but Still Efficient?

This paper investigates the importance of return heterogeneity and volatility for the foreign exchange rate on the New Taiwan (NT) dollar in terms of the U. S. dollar. We describe the price behavior of the foreign exchange market through the Power GARCH (1,1) and EGARCH (1,1) models. The time knots of market events are found to have deep impacts on the behavior of both market agents and the intraday characteristics of the price process. Evidence also reveals that Taiwan's foreign exchange market is semi-strong efficient.     

汇率风险对冲如何影响企业并购行为——基于自由现金流的视角

本文基于2001—2019年上市公司年报中关于外汇衍生品的使用信息,研究发现,使用外汇衍生品的上市公司相比未使用的公司发起并购的概率更低,但并购的市场和经营绩效有所提高。主要原因在于,中国上市公司进行并购通常以企业自有资金进行现金支付,外汇衍生品的使用大幅降低了公司出于预防性动机而持有的现金,从而降低了公司发起并购的概率。此外,进行汇率风险对冲可避免公司因持有大量自由现金流而发生的过度投资行为,从而提高了公司的投资效率。总体而言,使用外汇衍生品进行汇率风险对冲可使上市公司更注重并购质量而非并购数量,从而实现“少而精”的投资策略。本文研究对进一步厘清企业使用外汇衍生品的相关影响提供了一定参考。     

Concentration and foreign penetration in Latin American banking sectors: Impact on competition and risk

In the 1990s, Latin American banking sectors experienced an accelerated process of concentration and foreign penetration that prompted diverse views regarding its implications for the competitive behavior of banks and the financial stability of the system. In this paper, we examine these issues exploiting a rich bank-level database for eight Latin American countries. We find that, while increased concentration did not weaken banking competition within the region, foreign penetration appears to have led to a less competitive industry. Moreover, we find that bank risk has been negatively associated with competition which, coupled with the previous finding, explains the positive link between banking sector stability and foreign penetration revealed by the data.     

Pass-through and Exposure

Firms differ in the extent to which they "pass through" changes in exchange rates into foreign currency prices and in their "exposure" to exchange rates—the responsiveness of their profits to changes in exchange rates. Because pricing affects profitability, a firm's pass-through and exposure should be related. This paper develops models of exporting firms under imperfect competition to study these related phenomena. From these models we derive the optimal pass-through decisions and the resulting exchange rate exposure. The models are estimated on eight Japanese export industries using both the price data pass-through and financial data for exposure.     

人民币汇率波动如何影响中国企业的对外直接投资?

基于2005-2017 "中国全球投资跟踪数据库"的对外投资微观数据,本文考察人民币汇率波动的不确定性对中国企业对外直接投资的影响。研究发现:人民币汇率波动的增加,不仅减少了中国企业对外直接投资的可能性,也抑制了投资规模,这一结果在考虑内生性问题、样本选择性偏差、不同的汇率波动指标等一系列问题后仍然稳健。基于手工搜集的企业年报数据,研究发现,企业前期的套期保值行为,可以有效规避汇率风险,弱化汇率波动对企业对外投资的抑制作用。进一步研究显示,汇率波动对中国企业对外投资的影响有明显的异质性,投资于不同行业、不同国家的企业以及不同投资方式的企业对人民币汇率波动的反应各异,这又与中国现阶段对外投资的一些独特特征有关。本文研究为汇率波动影响中国企业的对外直接投资行为提供了微观层面的证据。     

我国外汇储备的溢出效应研究——基于引力模型的分析

本文采用2000-2015年199个国家和地区的外汇储备面板数据,基于引力模型理论,考察了我国高额外汇储备的溢出效应及对全球资产配置的影响。研究发现:我国外汇储备具有随地理距离递减的空间外溢效应,双边汇率制度关联会增加外汇储备持有比例的相似程度,而且这种溢出效应更多地表现在与中国金融发展水平类似、资本账户开放程度相近的国家之间。上述结论凸显了国家间加强外汇储备合作调整的战略意义。探究我国外汇储备的溢出效应,有利于发展中经济体更好地理解外汇储备的变动逻辑,对于完善外汇储备管理体制,参与国际宏观经济政策协调机制均具有一定的积极意义。     

汇率敏感性会影响企业贷款利率吗？——基于中国上市公司的分析

本文基于中国A股上市公司2009-2018年的数据,测算了企业价值对人民币汇率变动的敏感性。在此基础上,实证检验了汇率敏感性(企业价值对汇率变动的敏感程度)对企业贷款利率的影响和作用机制。研究发现:汇率敏感性与企业贷款利率之间显著正相关,且这种关系在拥有境外收入、境外投资和使用外汇衍生品的公司中更加显著。进一步分析发现,对于存在密切银企关系、较大的股东债权人利益冲突以及抵押品价值较低的企业,汇率敏感性与贷款利率之间的正相关关系更加显著。本文研究结果表明,随着我国市场化改革的进一步深化,贷款利率将会更加显著地反映企业的汇率敏感性特征。这种效应对于存在海外业务、银行更了解借款公司信息,以及违约可能性更高的公司更加明显。本文研究对于增强我国企业应对汇率风险能力,完善金融机构风险定价能力,引导金融机构服务实体企业具有一定参考意义。     

Do regulatory policies matter to corporate innovation?

This paper examines the relationship between regulation and innovation from both theoretical and empirical perspectives. The theoretical model focuses on the role of competition policy (measured by increases in the number of firms) and the strength of intellectual property rights in fostering cost-reducing R&D, under both R&D competition and R&D cooperation. It is shown that, theoretically, competition policy and intellectual property rights are complements under R&D competition, while they are substitutes under R&D cooperation. Moreover, under R&D competition, innovation is maximized through strict competition policy and strong intellectual property rights; whereas under R&D cooperation, innovation is maximized through strict competition policy and weak intellectual property rights. The empirical model tests the effect of several regulatory policies on innovation in several MENA countries. The results of dynamic panel data regressions point that competition policy and intellectual property rights are complements. In addition to competition policy and intellectual property rights protection, the following country/regulation characteristics are considered: human capital, government efficiency, foreign direct investment, natural resources dependence, labor market regulations, and GDP level. The paper finds that the extent of regulations in all categories has statistically significant effects on R&D, except FDI. One explanation is that most FDI to the MENA region flows to natural resources and non-tradable sectors, which are less relevant to R&D than other sectors (e.g., manufacturing and information and communications technology sectors).     

Dual foreign currency markets and the role of expectations: Evidence from the Pacific Basin countries

This paper analyzes the role of expectations about the government policy in the official foreign currency market in determining the black market premium. We use data for the recent float from six emerging markets of the Pacific Basin where active black markets for foreign currency exist, namely, Indonesia, Korea, Malaysia, the Philippines, Singapore and Thailand. To test the impact of anticipated and unanticipated shocks to the official exchange rate on the black market premium, we employ the two-step procedure of Hoffman et al. [Hoffman, D.L., Low, S.A., Schlagenhauf, D.E., 1984. Tests of rationality, neutrality and market efficiency: a Monte Carlo analysis of alternative test statistics. J. Monet. Econ. 14, 339–363] which provides corrected F-statistics and allows us to draw valid inference in the presence of generated regressors. The main finding of our analysis is that anticipated and unanticipated shocks to the official exchange rate have an impact on the black market premium in all six Pacific Basin countries. These results suggest that portfolio balance models provide the suitable theoretical framework for analyzing the behaviour of the black market premium in the markets for foreign currency in the Pacific Basin countries. Furthermore, this implies that economic agents in these countries are sensitive to expected returns in foreign exchange.     

Firm‐Level Competition and Exchange Rate Exposure: Evidence from a Global Survey of Firms

We examine the effect of competition on exchange rate exposure using survey data from 55 countries. We find that exposure increases with the intensity of competition. Exposure is higher when firms face price competition in international and domestic product markets and when rivals compete using an unfair financial advantage. Furthermore, competition is a leading determinant of exposure, dominating the usual determinants. Exposure also increases with several determinants not previously empirically examined, such as firm‐level financial constraints. These results hold for small, large, foreign‐involved, and purely domestic firms. Finally, import‐only firms have higher exposure than export‐only firms. Our survey results are likely to capture exposure before firms’ hedging actions.     

新凯因斯DSGE模型与货币政策法则之汇率动态分析

对于小型开放经济而言,当经济存在价格僵硬的情况下,中央银行在面对不同冲击发生时,各政策法则执行对汇率波动的影响及动态调整过程差异较大。从中国台湾地区的情况为案例来看,在稳定汇率波动方面:当国内技术冲击时,货币法则优于利率法则;当国外通货膨胀时,利率法则优于货币法则;当国外利率冲击时,执行利率法则或货币法则,其结果无显著差异。在汇率动态调整方面:当国外利率调升时,中央银行执行利率法则与货币法则下,汇率的瞬时反应为过度贬值;当国外物价膨胀时,执行利率法则与货币法则下,汇率的瞬时反应表现为立即升值;当国内技术进步冲击时,因为国外冲击对小型开放经济体系影响力道较强,使得国内技术进度对体系的影响相对较小,其中在利率法则下,汇率微幅贬值,而在货币法则下,汇率微幅升值。     

The size of banking crises in credible fixed exchange rate regimes

Since monetary policy is constrained in fixed exchange rate regimes, we should observe fewer banking crises due to moral hazard in countries with credible currency pegs. However, three countries with seemingly credible pegs in the nineteen-eighties and -nineties, namely China, Hong Kong and Argentina, still suffered crises in their domestic banking sectors. The present note illustrates that bank incentives to take on excess risk still exist in countries with currency peg credibility and that the size of that risk exposure (and thus the potential for crisis) may be positively related to the level of central bank foreign exchange reserves.     

Bandwagon effects and run patterns in exchange rates

I analyze the monthly exchange rates of the US dollar against the pound sterling, the Japanese yen, and the Swiss franc. All three exchange rates show bandwagon patterns, changes in one direction tend to be followed by changes in the same direction. This regularity points towards the importance of momentum traders on foreign exchange markets. A recent experimental analysis suggests the following hypothesis regarding the dynamics of bandwagon effects: if there is a repetition of similar occurrences many agents expect this run to continue but reduce the perceived chances of further repetitions when they actually occur. For exchange rates this implies that a continuation of a change in one direction should become weaker if an exchange rate has shown repeated changes in the same direction in the immediate past. This conjecture is supported by the findings of this study.
