Exchange rates have been highly volatile in Africa, especially since the move to a floating exchange rate system beginning in the 1980s. Generally, the pattern of exchange rate changes differs between Africa's two main sub-groups (CFA and non-CFA groups) due to the different monetary/exchange rate systems they adopted. This article therefore examines the effect of exchange rate volatility on the economic activities in Africa and its sub-groups during the period 1986–2011 using a panel data approach. Rational expectation theory informs the division of exchange rate into anticipated and unanticipated. Both the demand and supply channels are explored to trace the impact of the exchange rate volatility on price as well as aggregate demand and its components. Empirical results reveal differences in the impact of exchange rate volatility on economic activities between Africa's two sub-groups. Exchange rate volatility produced more significant effects in the non-CFA group than in the CFA group. 相似文献

In this article, the authors examine the relationship between the volatility in exchange rates and the volume of international trade in sub-Saharan African countries. Using the gravity equation and annual data for the period 1998–2007, they find a statistically significant and negative correlation between the volatility in exchange rates and the volume of trade. The estimated elasticities show that the responsiveness of the flow of international trade to changes in exchange rate volatility is very small. This suggests that eliminating the volatility in the exchange rates will result in only small increments in the volume of trade. Accordingly, pursuing a policy of exchange rate stability would not be sufficient to significantly increase the volume of bilateral trade in the sub-Saharan African region. 相似文献

This article develops a pricing model that incorporates an industrial organization approach with the traditional quantity theory of money to explain the impact of exchange rates on consumer prices. Using time-series data on prices and exchange rates of China, the model replicates the main features of the observed facts: exchange rates influence consumer prices through changing import prices; money supply and output influence consumer prices following the quantity theory. The estimating results show that exchange-rate pass-through to consumer prices is low and increases from the short run to the long run. The extent of pass-through is likely to depend on markup adjustment and marginal costs. 相似文献

贸易模式、汇率传递与人民币汇率安排 总被引:1,自引:0,他引:1
结合中国现行贸易模式的特点,文章从社会福利最大化目标入手,采用了新政治经济学中关于汇率制度战略选择的研究方法,对进一步扩大人民币汇率弹性和汇率升值的影响进行了分析.研究发现,加工贸易和一般贸易对汇率变动的反应弹性差异很大,不同国际贸易模式下的汇率传递系数是不同的.因此如果我国现行对外贸易依然以加工贸易为主,扩大汇率波动幅度在理论上并不会对我国社会福利产生严重影响.研究结果进一步支持加大汇率弹性更有利于丰富货币政策当局的工具选择范围,有助于国内货币政策独立性的保持,也有助于推进出口产业的结构调整和升级.是当前人民币汇率制度改革方向的合理选择. 相似文献

We apply the autoregressive conditional jump intensity (ARJI ) model to monthly exchange rate returns of China against 81 countries and investigate the impact of exchange rate volatility on exports over the period of 1995–2004. We decompose bilateral exchange rate volatility into continuous and discrete components and find that only the discrete part of exchange rate volatility, that is, the exchange rate jumps, has a significantly negative effect on exports, which to some extent reconciles the old yet unsettled debate in previous literature on the role of exchange rate volatility in international trade. There is also some evidence suggesting that the development of domestic financial market will boost international trade, but it does not help attenuate the negative effect of bilateral exchange rate jump risk on exports. 相似文献

AbstractThis paper measures the degree of bank competition in India using a sample of 70 commercial banks over the period 1996–2016. To assess the degree of competition, we estimate the market power of each bank in our sample employing three nonstructural measures: the Lerner index, the adjusted Lerner index, and the Boone indicator. Bank-wise and year-wise estimates of the marginal cost required in all these measures are obtained using the semi-parametric method. The paper further attempts to undertake a comprehensive assessment of competition in Indian banking and identifies various bank-specific, macroeconomic, structural, and contestability indicators, which are supposed to explain level and variation of the degree of competition over time. Empirical findings reveal that public-sector banks in India exercise a relatively higher degree of bank competition compared to private and foreign-sector banks. However, aggregate results support that the Indian banking system is competitive in general. Unlike the structure-conduct-performance paradigm, which advocates that a concentrated banking system impairs competitiveness, our findings reveal that concentration measures hardly exert any effect on bank competition. Rather, contestability measures play a significant role in the determination of bank competition. 相似文献

The study analyzes the impact of central bank intervention on the volatility of the exchange rate in Zambia during the period of 1996–2013. The empirical findings reveal a statistically weak negative impact of intervention on exchange rate volatility, suggesting that other policy instruments are required to augment foreign exchange interventions in dampening volatility in the exchange rate. 相似文献

This research article aims at examining the determinants of speed of adjustment (SOA) toward the optimum capital structure (OCS). Particularly, this study focuses the impact of firm-specific factors and corporate governance factors on the capital structure adjustment in the Sri Lankan context. The methodology utilizes the benefits of the partial (stock) adjustment model, namely, two-step panel framework using generalised method of moments (GMM) to determine the SOA to OCS. The results indicate that Sri Lankan firms are found to have an OCS and do rapidly adjust toward their target structures. Further this study reveals that profitability, size, tangibility, nondebt tax shields, and governance factors such as directors’ compensation and CEO duality significantly affect the SOA to OCS. The past studies in the emerging market context hardly go into corporate governance factors, leaving a large space for research in the area of capital structure. This study of the listed firms in Sri Lanka contributes to the literature, by examining the determinants of SOA to OCS decision. 相似文献

文章从汇率传递视角探讨了人民币名义有效汇率与贸易收支的关系。结论表明:首先,人民币汇率贬值和升值对贸易收支的影响存在非对称性,人民币升值对初级产品贸易收支、工业制成品贸易收支以及贸易总收支几乎没有影响;人民币贬值对工业制成品贸易收支和贸易总收支均存在显著性的影响,但对初级产品贸易收支没有影响。其次,人民币汇率变动对初级产品的净出口基本没有影响,其主要原因在于中国对金属矿砂、煤、焦炭、石油等主要初级产品的刚性需求以及中国在国际市场上对稀缺资源性产品定价权的缺失与不足。再次,人民币贬值不仅不能增加工业制成品净出口,反而恶化了工业制成品的贸易收支,究其原因,在于占较大比重的机械及运输设备类产品的进出口需求弹性较小。最后,本文在以上结论研究基础之上得到了许多有益启示。 相似文献

Impulse Control Method and Exchange Rate 总被引:3,自引:0,他引:3
We control a diffusion process with constant coefficients in order to keep this process in a given band with impulse control methods. We prove that there exists an optimal control if the cost associated with each control is a fixed cost plus a proportional cost. We study the problem of the exchange rate and prove that it is possible to keep the exchange rate in a target zone with discrete interventions. 相似文献

Non-linear relationships between growth opportunities and debt: Evidence from quoted Portuguese companies 总被引:1,自引:0,他引:1
This paper analyses the relationship between growth opportunities and debt of quoted Portuguese companies using various panel estimators. The results show a cubic relationship between growth opportunities and debt. When companies' growth opportunities are low and high, the relationship between growth opportunities and debt is positive. For intermediate levels of growth opportunities, the results show the existence of a negative relationship between growth opportunities and debt. These results suggest that the relationship between companies' growth opportunities and debt is influenced by complex aspects in companies' capital structure decisions. The empirical results suggest that creditors recognize high growth opportunities when such opportunities exist, and debt is a way to discipline managers' actions in the presence of low investment opportunities. For intermediate levels of growth opportunities, the subinvestment problems seem to be relevant in explaining the relationship between growth opportunities and debt. 相似文献

当前我国中小企业出口经营困境凸显,进一步汇改是否会加剧其困境成为关注的焦点。本文基于汇改后的月度数据,采用GARCH模型分析各次汇改对汇率弹性的影响特征,构建向量误差修正模型测度和预测汇改对中小企业出口的影响。结果表明:汇改促使人民币每升值1%,其出口减少3.874%;汇率弹性增强1%,其出口减少0.034%。预测的中小企业出口总额较为平稳。进一步汇改以增强汇率弹性为核心不会对中小企业出口总量造成大的冲击。 相似文献

This paper studies the relationship between exchange rate movements and the average export quality using disaggregated Swiss product-level data between 1996 and 2015. We find evidence at different levels of aggregation that the average export quality increases in response to a currency appreciation through compositional effects: currency appreciations shift market shares towards goods that are more expensive and of higher quality. This exchange rate effect on quality is more pronounced for differentiated goods and in sectors with a greater scope for quality differentiation. From a policy perspective, this reallocation effect points to the importance of facilitating structural changes in the export composition to increase the resilience of the export sector to exchange rate shocks. Our results also suggest a positive relationship between the average export quality and aggregate export sales. From a methodological point of view, the findings imply that exchange rate pass-through estimations without quality controls tend to be biased regardless of aggregation level or type of data. 相似文献

This paper describes and analyzes the implementation of a crawling exchange rate band on an electronic trading platform. The placement of limit orders at the central bank's target rate serves as a credible policy statement that may coordinate beliefs of market participants. We find for our sample that intervention increases exchange rate volatility (and spread) for the next minutes but that intervention days show a lower degree of volatility (and spread) than non-intervention days. We also show for intraday data that the price impact of interbank order flow is smaller on intervention days than on non-intervention days. These stabilizing effects, however, rely on the conditions of large currency reserves and the existence of capital controls; an electronic market seems to support this goal. 相似文献
