Bangladesh’s trade partners and the J-curve: an asymmetry analysis

Separating currency appreciations from depreciations and using non-linear models in recent literature have improved discovering significant link between the trade balance and the exchange rate. We add to this growing literature by considering the experience of Bangladesh with 11 trading partners. When a linear model was used, support for the J-curve effect was present only with one small partner. However, when a non-linear model was used, support increased to three countries including the largest partner, the United States, which accounts for more than 12% of Bangladesh’s trade. Furthermore, the non-linear models supported short-run asymmetry adjustment as well as short-run asymmetry effects of exchange rate changes in most cases. However, long-run asymmetric effects were limited to a few.     

Long-term effects of the asymmetry and persistence of the prediction of volatility: Evidence for the equity markets of Latin America

This article proposes an extension to the CGARCH model in order to capture the characteristics of short-run and long-run asymmetry and persistence, and examine their effects in modeling and forecasting the conditional volatility of the stock markets from the region of Latin America during the period from 2 January 1992 to 31 December 2014. In the sample analysis, the estimation results of the CGARCH-class model family reveal the presence of short-run and long-run significant asymmetric effects and long-run persistency in the structure of stock price return volatility. The empirical results also show that the use of symmetric and asymmetric loss functions and the statistical test of Hansen (2005) are sound alternatives for evaluating the predictive ability of the asymmetric CGARCH models. In addition, the inclusion of long-run asymmetry and long-run persistency in the variance equation improves significantly the out of sample volatility forecasts for emerging stock markets of Argentina and Mexico.

How do exchange rates co-move? A study on the currencies of five inflation-targeting countries

This paper does three things. First, it explores the type of asymmetry in exchange rate correlation for five inflation-targeting countries. We show their currencies co-move more closely with the currencies of some influential foreign countries during joint appreciations than joint depreciations against a world currency. Second, it establishes empirically the linkage between interest rate differentials and exchange rate correlation. We find evidence that both widening and narrowing interest rate differentials will reduce the correlation. Third, it proposes a new version of the asymmetric dynamic conditional correlation model. The model proves to be capable of providing great insight into the two issues investigated.     

Threshold cointegration,nonlinearity, and frequency domain causality relationship between stock price and Turkish Lira

Modelling complex asymmetric effects and non-linear relationships between exchange rate and stock prices has challenged classical econometric methods. This study contributes to the relative literature in the following distinct ways. First, we follow a variety of econometric approaches in order to characterize the complex dynamic co-movements between Turkish stock market and exchange rate from January 2003 to December 2018. Secondly, we show that the evidence for asymmetric threshold cointegration in Turkey’s financial market can be hidden by following linear time series methodologies. Thirdly, it is also worth noting that the real effective exchange rate, USD-Turkish lira exchange rates, money supply and interest rates have large predictive power for stock price fluctuations at various frequencies. Building on these insights, we claim that asymmetry (nonlinearity) is particularly important in Turkey’s financial market because it shows the need for a new pattern of policy measures to prevent financial market crisis risk in Turkey.     

人民币汇率变化及其传递对中国外贸平衡影响的实证分析

本文根据中国的14个主要贸易伙伴样本性质的不同，分别选用误差修正模型和几何分布滞后模型，检验了人民币双边汇率与双边贸易收支的关系，并计算分析了双边汇率对双边贸易收支的短期影响和长期影响及双边汇率对不同贸易伙伴的影响差别。分析表明，在长期人民币汇率贬值几乎能改善我国对所有贸易伙伴的贸易收支，马歇尔-勒纳条件成立；在短期人民币汇率贬值恶化我国对大多数贸易伙伴的贸易收支，马歇尔-勒纳条件可能不成立。双边汇率贬值对双边贸易收支的影响可能呈现“J”曲线或“W”曲线形态。人民币汇率变化对发达市场经济伙伴的贸易收支敏感度高于对其他贸易伙伴的敏感度，随着人民币汇率制度改革的深入，汇率的价格传递机制会逐渐完善，这些差别会逐渐缩小。     

Asymmetric herding as a source of asymmetric return volatility

As a considerable source of asymmetry in return volatility, this paper introduces asymmetric herding and extends the continuous beliefs system to account for its asymmetry and derive the asymmetric herding parameters that are easily estimated by using a maximum likelihood method based on the GARCH-type econometric model. This paper presents new empirical evidence for asymmetry in the exchange rates volatility of major currencies against the US dollar, which have bilateral nature. Interestingly, the asymmetry of Japanese yen is the opposite of that of others and the global financial crisis highlights the opposite asymmetry. Some of traditional hypotheses, such as the leverage effect and the volatility feedback effect, do not adequately explain these findings; however, a significant asymmetric herding effect is observed and appears to be time-varying. Further, the clear link between asymmetric herding and volatility strongly supports the hypothesis of the asymmetric herding effect.     

Asymmetric information and price competition in small business lending

This paper examines the relationship between bank lending rates and their cost of funds in New Zealand. Our results show that on average mortgage rates respond more quickly to changes in the cost of funds than base business lending rates. We also find an asymmetry in the initial (short-run) response of banks to changes in funding costs; in particular, our results show banks adjust mortgage rates downwards faster than upwards. The speed to which lending rates revert back to their equilibrium relationship with funding costs varies across the lending markets. We find the adjustment speed is faster when mortgage rates are below equilibrium, whereas it is slower when business lending rates are above long-run levels in relation to funding costs. Our analysis suggests that banks prefer the plain-vanilla type of lending such as mortgages in comparison to small business lending consistent with asymmetric information associated with business loans.     

Relationships among exchange rates, intervention, and interest rates: An empirical investigation

This study uses herefore unavailable daily data on official intervention to test the joint hypotheses of perfect asset substitutability and exchange market efficiency. This joint hypothesis is generally soundly rejected for six exchange rates over various sample periods. In contrast to evidence elsewhere from weekly or monthly data, lagged intervention is a significant determinant of realized profits in about half the cases; this evidence is consistent with existence of a portfolio-balance channel, at least in the short-run. Other evidence indicates that coordinated intervention sometimes may have an impact significantly different from intervention by one central bank alone.

Convertible securities in merger transactions

This paper provides a rationale for the use of convertible securities as the medium of exchange in corporate change-of-control transactions. We argue that convertible securities can resolve the information asymmetry about the bidder’s value while at the same time mitigating the information asymmetry about the target’s value. In contrast, deals with cash or stock can only address one information asymmetry or the other but not both. Empirically, we find that a bidder is more likely to offer convertible securities, rather than all cash or all stock, when both the bidder and its target face large asymmetric information problems. We also find that both bidders and targets in convertible deals enjoy positive abnormal stock returns around takeover announcements. These findings provide empirical support for the use of convertible securities to resolve the double-sided asymmetric information problem. Finally, we find that bidder returns in convertible deals are larger than in all-cash and all-stock deals, but that target returns in convertible deals are smaller than in all-cash and all-stock deals.     

Search Frictions,Labor Supply,and the Asymmetric Business Cycle

We develop a business cycle model that generates asymmetry between peaks and troughs of the unemployment rate and symmetric fluctuations of the participation rate as in the U.S. data. We calibrate the model and find that search frictions are solely responsible for the peak–trough asymmetry. Participation decisions do not generate asymmetry but contribute to the fluctuations in search frictions by changing the size and composition of the pool of job seekers, which in turn affects the tightness ratio and thereby slack in the labor market. The participation rate would be counterfactually asymmetric absent labor supply responses to shocks.     

Asymmetry Effects of Exchange Rate Changes on Domestic Production in Emerging Countries

Previous studies that tried to assess the impact of exchange rate changes on domestic production of emerging economies assumed that the effects are symmetric and used a linear model to provide mixed results. In this article, we try to determine whether exchange rate changes could have asymmetric effects which amounts to using a nonlinear model. We find that the nonlinear model performs much better than the linear model and yields results that support asymmetry effects of exchange rate changes on domestic production in many of the countries in our sample, both in the short run and in the long run.     

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。     

Do exchange rate changes have symmetric or asymmetric effects on stock prices?

Several macro variables have been identified as determinants of stock prices and exchange rate is among them. Exchange rate changes can affect different firms differently depending on whether they are export oriented or they use heavily imported inputs. Therefore, the overall effects of exchange rate changes on an aggregate stock price index could be in either direction. Previous research assumed that exchange rate changes have symmetric effects on stock prices. In this paper after introducing nonlinearity into adjustment process and after using Nonlinear ARDL approach to cointegration and error-correction modeling combined with monthly data from Brazil, Canada, Chile, Indonesia, Japan, Korea, Malaysia, Mexico, and the U.K., we show that exchange rate changes have asymmetric effects on stock prices, though the effects are mostly short-run.     

Asymmetric Impact of Oil Price Shock on Stock Market in China: A Combination Analysis Based on SVAR Model and NARDL Model

This article integrates the SVAR model and nonlinear ARDL (NARDL) model to analyze the long-run and short-run asymmetric effect of structural oil price shocks on the Chinese stock market. We reveal that the demand-side shocks of oil price have a significant impact on the Chinese stock market in both short and long run, but the supply shock is an exception. In terms of asymmetric nature, there is no evidence of asymmetric impact when it refers to the supply shock and the oil-specific demand shock on stock market, and only the aggregate demand shock has asymmetric effect in short run.     

Integration and interdependence of stock and foreign exchange markets: an Australian perspective

This paper examines the integration of the Australian stock market with its two leading trading partners, the US and Japan. In investigating the extent of integration, this study takes into account the interdependence between foreign exchange rates and stock prices, since exchange rates influence international competitiveness of firms, and, via interest rates, the cost of capital. The results indicate that there was a stable long-run relationship among the Australian, US and Japanese markets prior to the Asian crisis but that this relationship disappeared in the post-Asian crisis period. An analysis of the short-run dynamic linkages among markets suggests that, following the Asian crisis, the US influence on the Australian market diminished while the influence of Japan remained at a modest level. Furthermore, the impulse response analysis indicates only a contemporaneous transmission of shocks from one market to other markets. Confidence intervals for impulse responses are estimated using the bootstrap-after-bootstrap method.     

Pricing,issuance volume,and design of innovative securities: The role of investor information

This study investigates the role of asymmetric information for the pricing, issuance volume, and design of innovative securities. By analyzing the information that structured product issuers provide to the investors of those products, we can identify specific sources of asymmetric information between the issuers and investors in this market. We show that issuers exploit this information friction to offer products to investors that appear more profitable for the issuer. In addition, we find that the friction induces issuers to design products with higher information asymmetry. Our results suggest that product issuers’ behavior increases information frictions in the financial system.     

Information asymmetry,leverage and firm value: Do crisis and growth matter?

Drawing on pecking order and agency cost theories, we assess the extent to which information asymmetry is an important determinant of firm value and the extent to which this relationship is conditional on the leverage level of firms. We also assess the impact of information asymmetry on firm value during the pre and post 2007/09 financial crisis period and for high and low growth opportunity firms. Using a large sample of UK firms, our empirical findings suggest that information asymmetry adversely impacts firm value, and that this effect decreases with firm's leverage. We also find that leverage has a negative effect on firm value, and that the marginal effect of leverage is lower for information asymmetric firms. Further, we find that the relation between information asymmetry and firm value is more pronounced in the post-crisis period than the pre-crisis period. Finally, we show that the impact of information asymmetry on firm value is higher (lower) for firms with high (low) growth opportunities.     

Exchange-rate volatility and industry trade between the U.S. and Malaysia

Previous research that investigated the impact of exchange rate volatility on the trade flows of Malaysia concentrated only on the aggregate exports of Malaysia to the rest of the world. In this paper we first concentrate on the trade flows between Malaysia and the U.S. After showing that exchange rate volatility has neither short-run nor long-run effect on the trade flows between the two countries, we disaggregate the trade data by industry and consider the experience of 101 U.S. exporting industries to Malaysia and 17 U.S. importing industries from Malaysia. While exchange rate volatility seems to have significant short-run effects on the trade flows of most industries, short-run effects translate into the long run only in a limited number of small industries.
