农村金融发展对收入分配的机制分析与实证研究

在分析金融发展影响收入分配的传导机制的基础上,选择1978～2009年相关指标对城乡收入差距中金融发展因素进行实证研究。实证结果显示,农村金融发展规模、农村金融发展效率和农村金融发展结构等指标与农村经济发展的关系密切,但影响效果各有不同。当前,农村金融发展必须坚持以科学发展观为指导,按照统筹城乡经济金融协调发展的根本要求,继续深化农村金融体制改革,努力消除农村金融抑制,优化农村金融发展结构,建立适应社会主义市场经济发展根本要求的农村金融体系。     

Risk and ethical investment: Empirical evidence from Dow Jones Islamic indexes

This paper contributes to the literature on the impact of the Shari’ah filtering criteria on the risk of Dow Jones Islamic indexes relative to their conventional counterparts. We show that Islamic and conventional indexes are affected by the same extreme events which can bias the estimation of the risk, especially the period of the Global Financial Crisis of 2007–2008 and its aftermath which is characterized by a very high level of volatility. Then, we examine whether the Islamic indexes are more risky than the conventional indexes using different risk measures. We also analyze the performance of both indexes from various risk-adjusted performance measures. Overall, the Islamic indexes seem to be more risky than their conventional counterparts as well as exhibit a higher performance on the full period (1996–2013). The sample period is further divided into low volatility period and high volatility period based on the detection of structural breaks in the volatility. The results also show that both indexes have been affected by variance changes. We show that most of the Islamic indexes have higher level of risk than the conventional indexes, whatever the sub-periods. Consequently, this finding means that the Islamic indexes are riskier than the non-Islamic indexes. We also find that in most cases the Islamic indexes either outperform the non-Islamic indexes or there is no significant difference in performance between both indexes. These findings can be explained as a consequence of less diversification in Islamic indexes, leading to higher concentration risk in some sectors, such as basic material, industrial and technology firms. Further, we find some differences of risk and performance between the jurisdictions.

Efficiency and Dynamics of Islamic Investment: Evidence of Geopolitical Effects on Dow Jones Islamic Market Indexes

This paper analyzes both the market quality and price dynamics of a sample group of Islamic indexes. Our results highlight that efficient investment allocation is not compromised by the application of Shariah criteria. However, although few indexes impose an additional liquidity cost on investors, a vast majority of indexes present degrees of liquidity that are similar to conventional indexes. Ultimately, investors whose investment decisions are guided by religious principles do not bear significant additional costs of inefficiency but may have to accept that their portfolios are more sensitive to geopolitical events. However, Islamic indexes may contribute to the international diversification of investors' portfolios.

Temporal aggregation of the Aumann–Serrano and Foster–Hart performance indexes

We investigate the temporal aggregation of the Aumann–Serrano (AS) and Foster–Hart (FH) performance indexes considered by Kadan and Liu (2014). We provide sufficient conditions for the two indexes to be closed under temporal aggregation, that is, for the two indexes to have the same values when the observations are aggregated. Here, we present empirical examples using U.S. stock data and the four anomalies studied by Fama and French (1993) and Carhart (1997), where the two indexes have nearly identical values in some stocks and one anomaly when the observations are aggregated. Unlike the Sharpe ratio, the AS and FH performance indexes have more stable properties with respect to temporal aggregation.     

Are Islamic stock indexes exposed to systemic risk? Multivariate GARCH estimation of CoVaR

The main objective of this paper is to assess the exposure of Islamic stock indexes to systemic tail events. We use Conditional Value-at-Risk (CoVaR) and Delta CoVaR measures as developed by Adrian and Brunnermeier (2011) and a sample of Islamic and conventional stock indexes, from various developed and emerging markets, during the period September 2005 to March 2015. The empirical results reveal that the systemic risk has a moderate adverse effect on Islamic indexes, with a lower level in Gulf Cooperation Council countries (GCC hereafter). The findings also show the Asian stock indexes can be considered as effective hedge assets, after the global financial crisis (GFC hereafter). Furthermore, the empirical reveal that portfolio including Islamic stock indexes performs better than a benchmark portfolio in turmoil periods. These findings have several implications in financial decisions including the strategy of stability and asset allocation.     

The Reversal of the Monday Effect: New Evidence from US Equity Markets

This article re-examines the Monday effect in the US stock market from 1964–1999 using daily returns from three large-cap indexes and two small-cap indexes. In the period before 1987, Monday returns are significantly negative in all five US stock indexes, confirming previous empirical findings. In the post-1987 period, we uncover a significant reversal of the Monday effect in the large-cap indexes (NYSE, S&38;P500 and DJCOMP), since Monday returns are significantly positive. Furthermore, significant differences in the persistence and reversal of the Monday effect are found between large-cap and small-cap stock indexes.

Revisiting conventional and green finance spillover in post-COVID world: Evidence from robust econometric models

In 2020, ESG funds that invest in companies that score higher on environmental, social, and governance measures witnessed an increase in investment compared to 2019. Understanding the causal relationship and spillover between these two types of indexes may help investors determine if clean energy indexes follow the same trend as conventional indexes or the reverse. Additionally, investors would benefit from understanding this causation in both the pre- and post-Covid-19 eras. We conceive this study to plug this gap and advance the knowledge in this critical area. We study the causality and spillover between NASDAQ clean energy indexes, and their corresponding alternatives namely, NASDAQ Composite Index and NASDAQ Global Select Market Composite using the daily data and from 1 st January 2011 to 29 th June 2021. We apply the Granger-Causality test and the spillover models approach by Diebold and Yilmaz (2012) and Baruník and Křehlík (2018) to determine any medium-run, or long-run causality, and spillover between the indexes under reference, respectively. Our results suggest us to observe that both sustainable and green indexes exhibit bi-directional causality where both sets of indexes impact each other in the long-run. Additionally, after the emergence of the COVID-19 pandemic, the connectivity between the two sets of indices rose significantly. Our findings also suggest that the investors will not lose on risk-adjusted returns if they chose to go green. With the investors' ability to shift towards green investment without losing on financial returns, it shall become even easier for businesses to steer their operations.     

Market segmentation and international diversification across country and industry portfolios

We conjecture that partially segmented stock indexes that are characterized by low correlation with the world market are mainly priced by local factors and should produce abnormal returns relative to a global asset-pricing model. This implies a negative relation between correlation and future index returns in the presence of segmented indexes. Empirical evidence confirms such a relationship for the sample of industry indexes, suggesting a heterogeneous segmentation. However, we do not observe a similar pattern for country indexes. In addition, the international diversification potential of industries does not vanish during volatile periods. The hypothesis that the negative relationship should be stronger for the more segmented subsamples that are characterized by small market size and emerging country origin is verified for the industry sample. Thus, cross-industry diversification is superior to mere cross-country diversification.     

Are there Monday effects in stock returns: A stochastic dominance approach

We provide a test of the Monday effect in daily stock index returns. Unlike previous studies we define the Monday effect based on the stochastic dominance criterion. This is a stronger criterion than those based on comparing means used in previous work and has a well defined economic meaning. We apply our test to a number of stock indexes including US large caps and small caps as well as UK and Japanese indexes. We find strong evidence of a Monday effect in many cases under this stronger criterion. The effect has reversed or weakened in the Dow Jones and S&P 500 indexes post 1987, but is still strong in more broadly based indexes like the NASDAQ, the Russell 2000 and the CRSP.     

Estimating Real Estate Price Movements for High Frequency Tradable Indexes in a Scarce Data Environment

Indexes of commercial property prices face much scarcer transactions data than housing indexes, yet the advent of tradable derivatives on commercial property places a premium on both high frequency and accuracy of such indexes. The dilemma is that with scarce data a low-frequency return index (such as annual) is necessary to accumulate enough sales data in each period. This paper presents an approach to address this problem using a two-stage frequency conversion procedure, by first estimating lower-frequency indexes staggered in time, and then applying a generalized inverse estimator to convert from lower to higher frequency return series. The two-stage procedure can improve the accuracy of high-frequency indexes in scarce data environments. In this paper the method is demonstrated and analyzed by application to empirical commercial property repeat-sales data.     

Deterministic nonlinearity in the stock returns of major European equity markets and the United States

By using recently developed statistical tools designed to overcome some of the limitations often associated with financial data, this study attempts to detect low-dimensional deterministic chaos in five major European stock markets and the United States. Country indexes exhibiting low-dimensional deterministic chaos may contain some informational inefficiency; thus, it may be possible to use nonlinear dynamics to predict future stock returns. The results do not provide evidence of the existence of low-dimensional chaotic systems in any of the examined indexes. As such, the notion of market efficiency in the examined indexes is not threatened by the findings of this study.

Do fundamental indexes produce higher risk-adjusted returns than market cap indexes? Evidence for European stock markets

A fundamental index weighs stocks proportionally to fundamentals such as book value, dividends, or sales. We investigate risk/return characteristics of fundamentally-weighted and market-cap-weighted indexes and employ various risk-adjustment approaches to ensure that return differences are not driven by risk. Based on stocks in the DJ Stoxx 600 index from July 1993 to April 2007, we show that fundamentally-weighted indexes achieve higher risk-adjusted returns than market-cap-weighted indexes. Our results provide empirical evidence for former theoretical findings that cap weighting may result in suboptimal risk/return characteristics.     

Safe havens in Islamic financial markets: COVID-19 versus GFC

Using a bivariate dynamic conditional correlation (DCC) generalized autoregressive conditional heteroskedasticity (GARCH) model, this study compares the safe-haven properties of various assets against the major Gulf Cooperation Council (GCC) stock indexes during two periods of financial turmoil, the COVID-19 pandemic and the 2008 Global Financial Crisis (GFC). Sovereign bonds offered the highest hedging benefits under both crises. The traditional safe assets, gold and silver, which were reasonably productive under the GFC, have been less so during the pandemic. The Japanese yen emerged as a very safe choice for investors holding GCC stock indexes. Both sector indexes and stock indexes failed to safeguard investors most of the time during each crisis.
