国家金融安全的杠杆──发展中国家汇率制度的选择

世界金融一体化已成为二十一世纪主要经济特征,并强烈的影响着发展中国家的金融政策,关乎国家金融安全,而选择适当的汇率制度则是解决这一问题的杠杆。本文从时间和空间两个角度出发,历史地比较地分析了发展中国家汇率制度的选择要素、内在结构及其战略取向。     

商业银行资产负债期限结构的错位与债务业务创新

中国银行业长期面临的资产负债期限结构错配的问题正日趋严重。商业银行这种以短期负债支撑长期资产的所谓“短存长贷”现象,极易引发流动性风险,一旦出现储蓄存款减少或发生挤提,很容易产生支付危机。本文提出债券业务创新是解决上述问题的一个切实可行的选择,通过债券业务创新,有助于改变我国商业银行负债管理能力偏弱的状况,同时也可以提高资产的流动性,降低利率风险,增强资产管理的灵活性。     

Impact of an unexplained component of real exchange rate volatility on FDI: Evidence from transition countries

The aim of this paper is to examine the impact of an unexplained component of real exchange rate volatility on FDI in transition economies. We make an attempt to overcome some problems associated with previous studies; the aggregation problem, inadequate measures of volatility, short-run focus and the endogeneity problem. Using a GARCH specification, we focus on long-run volatility, while we control for the endogeneity problem by applying SYS-GMM estimation. The obtained results show that the impact of the unexplained component of real exchange rate volatility on FDI differs among economic activities since 2000. As part of the re-estimation exercise, we use two alternative measures of volatility to avoid arbitrariness. The obtained results are to a large extent in accordance with the first one.     

Testing moving average trading strategies on ETFs

The evidence for the profitability of MA strategies documented in the literature is usually based on non-tradable indices or portfolios/factors and the use of the zero return or risk-free rate as the benchmark. In this paper we implement MA strategies using ETFs and examine the performance of such strategies using a variety of risk-adjusted performance measures. We find that relative to the buy-and-hold strategy, MA strategies have lower average returns and Sharpe ratios, but fare better under factor-adjusted performance measures such as the CAPM alpha. We also find that MA strategies become less profitable when they are implemented using ETFs than using their underlying indices. In addition, we propose a quasi-intraday version of the standard MA strategy (QUIMA) that allows investors to trade immediately upon observing MA crossover signals. The QUIMA strategy outperforms the standard one that only trades at the close of a trading day, when the long-term MA lag length is no more than 50 days.

The gender difference in wages and the returns to schooling over the great recession in the U.S.

This paper examines the effects of the Great Recession on the gender difference in hourly wage and the rate of return to schooling in the United States. Using data from American Community Survey 2000–2015, we find that the male-female difference in hourly wage declined during and after the recession. The Great Recession decreased earnings for both men and women, especially for those with more education. We also find there is a significant gender difference in the effects of the Great Recession on the returns to schooling. The Great Recession increased the rate of return to schooling for both men and women, and the female-male difference in the returns to schooling decreased by 0.4 percentage points in the post-recession period. The change of the gender difference in the returns to schooling can be explained by the wage structure change for men and women over the recession.     

Exchange rates and fundamentals: A bootstrap panel data analysis

This study attempts to re-examine the Granger non-causality from exchange rates to observed fundamentals based on the present value model of Engel and West (2005). To this end, we employ the bootstrap panel Granger non-causality analysis, which allows us to untangle the causal nexus between exchange rates and fundamentals in panel data. Among the main results, it is found that the null hypothesis of no cross-sectional dependence across the members of the panel is strongly rejected, indicating that the bootstrap critical value is required in conducting the panel Granger non-causality test. The null hypothesis of Granger non-causality running from the fundamentals to exchange rates is significantly rejected, implying that the monetary approach of exchange rate determination is a useful benchmark to understand the evolution of the exchange rate. Empirical evidences also show that exchange rates Granger-case the fundamentals, supporting the view that exchange rates are determined as the present value that depends in part on observed fundamentals.     

A re-examination of the impacts of macroeconomic and financial shocks on real exchange rate fluctuation: evidence from G7 and Asian countries

ABSTRACT

This paper aims to investigate the sources of real exchange rate fluctuation by utilizing sign restrictions in structural vector autoregressive (SVAR) method. Under an agnostic identification scheme, the empirical results show that the delayed overshooting puzzle still exists in response to monetary shock even if price puzzle is ruled out by construction. In contrast, all countries experience a significant initial real depreciation, and then gradually appreciate in response to currency risk premium (CRP) shock. This finding is consistent with Dornbusch’s overshooting model. In addition, I examine the importance of investors’ expectations in determining the short-term variations in the real exchange rate. The results indicate that the CRP and expectation shocks obviously outperformed the demand, supply and monetary shocks in terms of explaining the real exchange rate fluctuation.     

开放经济下的“双支柱”调控稳定效应研究

本文研究了管理浮动汇率制下我国货币政策和宏观审慎政策双支柱的调控稳定效应。首先,本文从实证层面考察了人民币汇率升贬值对央行货币政策的非对称影响。接着,本文构建了包含银行部门与货币错配的开放宏观经济模型,重点分析了在面对美联储加息、人民币贬值压力的情况下,货币政策(包括对汇率的反应)和宏观审慎政策(对外债的逆周期调节)的配合如何影响宏观经济和金融的稳定。结论表明,如果缺少宏观审慎政策的配合,货币政策对汇率的反应将导致产出、通货膨胀和资产价格等经济金融变量的波动增大。在存在宏观审慎政策的前提下,相对于完全浮动汇率制,管理浮动汇率制从中长期看能进一步促进产出和外债等核心变量的稳定。
