自20世纪70年代初期布雷顿森林体系崩溃之后,美国割断了美元与黄金的固定比价关系,使黄金价格步入了市场化的轨道,黄金价格的大幅波动越演越烈,这使得人们越来越重视探讨影响黄金价格的种种因素。为此,利用VAR模型对黄金价格自身、美国通货膨胀率、国际原油价格等因素与黄金价格总水平的关系进行研究。通过研究得到了各因素影响黄金价格总水平的程度,其中发现黄金价格自身的波动是导致国际黄金价格总水平上升的最主要因素,这为研究黄金价格的变动提供了重要依据。 相似文献

In this paper, we propose a new algorithm to find the optimal static replicating portfolios for general path-independent nonlinear pay-off functions and give an estimate for the rate of convergence that is absent in the literature. We choose the static replication by designing an adaptation function arising in the error bound between the nonlinear pay-off function and the linear spline approximation and derive the equidistribution equation for selecting the optimal strikes. The numerical tests for variance swaps, swaptions, static quadratic hedges and also for a jump-diffusion process, allowing for the default of the underlying asset, show that the proposed iterative equidistribution equation algorithm is simple, fast and accurate. The paper generalizes and improves the results on static replication and approximation in the literature. 相似文献

Using as an example data on official Japanese interventions in the yen/dollar market, I show that techniques developed to analyse relative operating characteristic (ROC) curves can be useful to study the forecasting value and effectiveness of interventions. 相似文献

Using Bayesian model averaging, we determine which fundamental pair-wise differences suggested by the literature on optimum currency areas give the best explanation of medium-term variability of bilateral real exchange rates. The intercept in the best specification is statistically insignificant, implying that for a hypothetical pair of economies for which the differences were zero, the bilateral real exchange rate would not move. Thus, the ‘non-fundamental’ element of the medium-term real exchange rate variability is, in our sample at least, negligible on average. In other words, floating exchange rate does not in itself imply, on average, more real exchange rate variability in the medium term than an exchange rate peg. 相似文献

This paper addresses the issue of competition in dual banking markets by analyzing the determinants of deposit rates in Islamic and conventional banks. Using a sample of 20 countries with dual banking systems over the 2000–2014 period, our results show significant differences in the drivers of Islamic and conventional banks' pricing behavior. Conventional banks with stronger market power set lower deposit rates but market power is not significant for Islamic banks. In predominantly Muslim environments, conventional banks set higher deposit rates and further higher when their market power is lower. Whereas conventional banks are influenced by the competitiveness of Islamic banks, Islamic banks are only affected by their peers in predominantly Muslim countries. Our findings have important implications regarding competition and bank stability in dual banking markets. 相似文献

The paper tests the validity of the Balassa-Samuelson hypothesis (BSH) using the within-effects and the dynamic panel generalised methods of moment (GMM) techniques for a panel of eight middle-income African countries over the period 1960–2009. We selected these countries because they exhibited a mixture of relative productivity growth and real exchange rate misalignment that fits the characterization of the BSH well. The results strongly support the BSH for this group of countries. The results are valid even after we controlled for potentially omitted variables and endogeneity. The implication is that as these countries become more productive, their currencies appreciate in real terms. 相似文献

The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labour as an important ingredient. This article shows how the recent huge migrants’ inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labour market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modelled adequately compared to results based on the unadjusted European Commission procedure. 相似文献

This exploratory study seeks to add to the income tax evasion literature by investigating a heretofore ignored potential determinant of aggregate federal personal income tax evasion in the U.S., namely, the labour force participation rate. It is hypothesized that the higher (lower) the labour force participation rate, the lower (greater) the degree of tax evasion. The empirical estimation supports this hypothesis, finding that a one unit (one percentage point) increase (decrease) in the labour force participation rate leads to a 9.1% decrease (increase) in income tax evasion. Thus, the declining labour force participation in recent years implies increased tax evasion problems for the U.S. 相似文献

2017年5月26日,中国外汇交易中心人民币兑美元中间价报价机制中引入逆周期因子。本文利用引入新因子以来外汇市场交易数据,通过新的人民币汇率中间价定价机制,测算了逆周期因子数值。在此基础上,本文通过构建VAR模型和EGARCH模型研究了逆周期因子对人民币汇率走势和人民币汇率波动性的影响。研究表明,引入逆周期因子降低了人民币汇率波动性,但对人民币汇率的走势没有显著影响。逆周期因子修正了投资者对汇率变动顺周期性的过度反应,有利于引导市场预期,完善人民币汇率宏观审慎管理。 相似文献

2013年我国人均GDP达到6900美元,标志着我国已居于“上中等收入”国家行列,正面临“中等收入陷阱”的威胁。本文基于日本、韩国、巴西和阿根廷的发展历程,考察了“中等收入陷阱”区间下消费率的变化轨迹,认为成功跨越“中等收入陷阱”的消费率特征是:消费率走势呈U型特征,由波动性变化演变为平稳性运行,并大致在人均GDP4000美元形成“消费率拐点”。其中,收入因素对“消费率拐点”的培育与形成具有较大的制约作用。同时文章对比分析了低中等收入阶段我国消费率变化轨迹,认为我国在人均GDP4283美元水平下形成“消费率拐点”,但当前消费需求的充分释放仍面临较强的挑战,迫切需要相应的政策措施来强化“消费率拐点”的形成。 相似文献
