Which Chinese Markets to Diversify into?

This paper investigates the correlation and feedback relationships between the Hong Kong Hang Seng Index (HSI), the Hang Seng Chinese Enterprise Index (CEI) and the S&P 500 Index (SP). We divide the indexes into two separate periods, from the inception of the CEI in 1994 to the stock market crash in 2000, and from 2001 to 2011. Our results show that the feedback relationship between the CEI and the SP is stronger after 2000. As the feedback relationship grows stronger, the diversification benefit reduces for US investors who utilizes the CEI as a tool for diversifying into Chinese markets.     

Time varying price discovery of the New Third Board market in China: does the market-making system help?

This paper examines whether the market-making system helps to improve the price discovery ability of New Third Board (NTB) market in China. We first estimate the time-varying coefficients error correction models, then apply common factor weight method to quantify the time-varying price discovery contributions, and finally explore the impacts of trading volume and volatility to price discovery contributions. Empirical results show that both markets have time-varying characteristic in terms of the magnitudes and directions of the equilibrium price adjustment due to error correction term. The Shanghai Composite Index, SZSE Component Index, and SME Index are found to lead in price discovery, while NTB exhibits the leadership on the GEM Index. Volume and volatility have significant influence on the price discovery contribution. The NTB contribution is positively related to its own trading activity, negatively related to the trading activity of Shanghai and Shenzhen stock markets, while negatively correlated with the volatility of both markets. In comparison, trading activity of SZSE Component Index and volatility of GEM Index have the greatest negative impacts on the contribution of NTB market. As an important part of China’s multi-level capital market, the pricing mechanism of the NTB market needs further to be improved.

Assessment of India's research literature

The structure and infrastructure of the Indian research literature were determined. A representative database of technical articles was extracted from the Science Citation Index/Social Science Citation Index (SCI/SSCI) [SCI. Certain data included herein are derived from the Science Citation Index/Social Science Citation Index prepared by the THOMSON SCIENTIFIC®, Inc. (Thomson®), Philadelphia, Pennsylvania, USA: ©Copyright THOMSON SCIENTIFIC® 2006. All rights reserved. [1]] for 2005, with each article containing at least one author with an India address. Document clustering was used to identify the main technical themes (core competencies) of Indian research. Aggregate India bibliometrics were also performed, emphasizing the value of collaborative research to India. A unique mapping approach was used to identify networks of organizations that published together, networks of organizations with common technical interests, and especially those organizations with common technical interests that did not co-publish extensively. Finally, trend analyses were performed using other year data from the SCI/SSCI to place the 2005 results in their proper historical context.     

An investigation into the interdependence of global water indices: a VAR analysis

We investigate the extent and manner of equity price interdependence among four water indices – World Water Index, S-Network Global Water index (S-Net), S&P Global Water Index (S&P) and MSCI ACWI Water Utilities Index (MSCI ACWI) using the vector autoregression (VAR) framework for the period 2004–2014. We also employ methods of Granger causalities, variance decomposition and impulse responses. We find Granger causality significance between S-Net and MSCI ACWI and S-Net and S&P indices at the 1% level of significance, suggesting that the indices are significantly linked. Further, S-Net is the most influential index amongst them in the forecast variance that can be accounted by S-Net at level of 55.75%. Our study indicates that the four water indices are interdependent and related, so the water indices are influenced by movements in the other water indices.

Chinese science and technology — Structure and infrastructure

This paper identifies and analyzes the science and technology core competencies of China, based on a sampling of approximately half of the total Chinese publication output in the Science Citation Index/ Social Science Citation Index (SCI/SSCI) [SCI. Certain data included herein are derived from the Science Citation Index/Social Science Citation Index prepared by the Thomson Scientific®, Inc. (Thomson®), Philadelphia, Pennsylvania, USA: © Copyright Thomson Scientific® 2006. All rights reserved. [1]] for 2005. Aggregate China publication and citation bibliometrics were obtained and a hierarchical research taxonomy, based on document clustering, was generated. Additionally, bibliometrics and thematic trends were tracked over the past two decades.The key findings were that China's output of research articles has significantly expanded in the last decade. In terms of sheer numbers of research articles, especially in cuting-edge technologies, such as nanotechnology and energetic materials, it is among the leaders. Compared to the USA, the bulk of China's articles focus on the physical and engineering sciences, while the USA articles (compared to China) focus on medical, social, and psychological sciences.     

HOW SHOULD WE MEASURE THE “ECONOMIC” ASPECTS OF WELL‐BEING?

The Human Development Index (HDI) uses GDP per capita to measure “command over resources,” which implicitly makes the strong value judgment that inequality and insecurity do not matter. This paper presents revised estimates of the Index of Economic Well‐Being (IEWB) for the United States, the U.K., Canada, Australia, Germany, Norway and Sweden for the period 1980 to 2001 and demonstrates that replacing an index of the log per capita incomes with our IEWB as the “command over resources” component in the Human Development Index (HDI) affects the level and trend of the HDI, even among affluent nations. Because the IEWB recognizes four dimensions of command over resources (Current effective per capita Consumption flows, Net societal Accumulation of stocks of productive resources, Income Distribution and Economic Security), its use has a particularly large impact where underlying trends in these components diverge (e.g. the U.K. or the United States).     

Early warning signals using AVaRs of infinitely divisible GARCH models — evidence from stock index markets

Classical time series models have failed to properly assess the risks that are associated with large adverse stock price behaviour. This article contributes to autoregressive moving average model–GARCH (ARMA–GARCH) models with standard infinitely divisible innovations and assesses the performance of these models by comparing them with other time series models that have normal innovation. We discuss the limitations of value at risk (VaR) and aim to develop early warning signal models using average value at risk (AVaRs) based on the ARMA–GARCH model with standard infinitely divisible innovations. Empirical results for the daily Dow Jones Industrial Average Index, the England Financial Times Stock Exchange 100 Index and the Japan Nikkei 225 Index reveal that estimating AVaRs for the ARMA–GARCH model with standard infinitely divisible innovations offers an improvement over prevailing models for evaluating stock market risk exposure during periods of distress in financial markets and provides a suitable early warning signal in both extreme events and highly volatile markets.     

Nutrient Prices and Other Socio-Economic and Health Determinants of the Body Mass Index of Canadians

We examine the effect of nutrient prices and other socio-economic and health factors on the Body Mass Index (BMI) of Canadians using the Canadian Community Health Survey (CCHS). The CCHS data does not include information on nutrition intake, and so the price of fat, carbohydrates and protein are included to capture the effects of diet on BMI. The results indicate that changes in nutrient prices in the model have statistically significant impacts on BMI and the direction of the impacts corresponds to hypotheses from the nutrition literature. However, all estimates are inelastic so that the effect of fat taxes or thin subsidies is small. The results also indicate that education is negatively related and income is positively related to BMI.     

Relative prices and inflation: new evidence from different inflationary contexts

This paper analyses the relationship between inflation and relative price variability, in the direction of the latter, in two countries with very different inflationary experiences: Argentina and Spain. To address this objective, using disaggregated price indexes (the Wholesale Price Index for Argentina and the Consumer Price Index for Spain), we delimitate different inflationary regimes and compute a set of regressions for each country. Our results suggest evidence in favour of the non-neutrality of inflation (mostly in hyperinflation periods) and do not support either the menu costs or the signal extraction approaches. We also detect significant structural changes in the relationship depending on the inflationary regime.     

The Correct Conception of Capital: A Reply to Baldwin Ranson

This paper assesses the economic importance and the limits of using the Economic Freedom Index (EFI) to help explain and realize higher levels of per-capita income. Specifically, I elaborate on the need to disaggregate and place the EFI into a coherent and meaningful theoretical context in order to generate economically cogent analytical predictions as well as more reasonable public policy recommendations. As it stands, the EFI can produce highly misleading causal results with potentially disastrous consequences for public policy. Hereby, I make a preliminary attempt at constructing an alternative aggregate index to measure the importance of market-related institutions for achieving higher levels of per-capita income. This alternative index, termed here the Good Capitalist Governance Index (GCGI), better correlates with per-capita income and has a higher threshold value than the Economic Freedom Index. The GCGI highlights the importance of secure private rights, limited corruption, and sound money for the realization of higher levels of per-capita income. The evidence supports the hypothesis that good capitalist governance requires a well-working, but not minimalist government.     

RISK PERCEPTION AND EQUITY RETURNS: EVIDENCE FROM THE SPX AND VIX

We use the semi‐nonparametric (SNP) model to study the relationship between the innovation of the Volatility Index (VIX) and the expected S&P 500 Index (SPX) returns. We estimate the one‐step‐ahead contemporaneous relation subject to leverage GARCH effect. Results agree with a body of newly established literature arguing non‐linearity, and asymmetries. In addition, the risk‐return behaviour depends on the signs as well as magnitudes of the perceived risk. We conclude that influence of fear or exuberance on the conditional market return is non‐monotonic and hump‐shaped. Very deep fear does not necessarily mean huge losses, instead, the loss may not be as bad as fears of normal levels. Results pass the robustness tests.     

福利水平的可持续性评价研究

在设计福利水平的评价指标和可持续发展评价指标时,一些评价福利水平的指标忽视了可持续性,而评价可持续发展的指标则忽略了当前的福利水平。长期以来,人们一方面试图用一个单一的指标来综合反映可持续发展和福利水平两个方面的内容;另一方面,也在探讨不将两方面的内容完全综合为一个指标的情况下,如何结合应用两个方面的测度指标。本文首先针对第一方面的问题以ISEW为例进行述评;其次,述评第二方面的不同建议;再次,提出将真实储蓄率作为可持续指标,并以此来评判福利水平的可持续性。     

Time-frequency comovement among green financial assets and cryptocurrency uncertainties

The high energy consumption and carbon footprints have raised environmental and sustainable concerns of green investors and policymakers. This study explores comovements between three green and socially responsible financial assets, S&P global clean energy index (GCEI), S&P green bonds index (GB), DJ sustainability world index (DJSWI) and four cryptocurrency uncertainty/attention indices cryptocurrency policy uncertainty index, Central Bank Digital Currencies Uncertainty Index, Central Bank Digital Currencies Attentions Index and Index of Cryptocurrency Environmental Attention using the bivariate wavelet coherence approach. The findings show that GCEI, GB, DJSWI returns have consistent positive comovement with all cryptocurrency uncertainty/attention indices in the medium-term, suggesting their time-varying leading role. Evidence of negative coherences shows that higher cryptocurrency uncertainties/attentions lead to lower green financial asset returns, reflecting the adverse impact of higher uncertainties/attention on the trust of green and sustainable investors. The above empirical findings offer up-to-date insights for guiding policymakers, and regulators, enabling them in environmental policy development. Furthermore, socially responsible investors can make better investment judgments by considering the environmental concerns in the cryptocurrency marketplaces.     

Investor sentiment and risk appetite of real estate security market

This article proposes a new model to measure the risk appetite in absence of option prices. Without options transaction, traditional measurements cannot be made. This article establishes a Risk Appetite (RA) indicator by way of change measure and simulation, with two density functions, i.e. risk-neutral density and historical density. The RA indicators use the data from the Property Composite Index (PCI) and the Shanghai Stock Exchange Composite Index (SSECI). The empirical result shows that investors involved in the real estate security market have lower RA compared to those in the general security market. Particularly, RA indicators for both indices started to fall markedly in early 2008 and even more so after September 2008. The changes in RA suggest that the overall investors’ attitudes nowadays towards China's stock market are never as pessimistic as before.     

Market Size and Investment Performance of Defaulted Bonds and Bank Loans: 1987–2001

The defaulted and distressed, public and private debt markets in the United States swelled to a record $680 billion (face value) at the end of 2001. The market value of this 'niche' segment was approximately $400 billion.
Defaulted security investors enjoyed an excellent year on average, as returns in 2001 were 17.5 per cent on bonds, 13.9 per cent on bank loans, and 15.6 per cent combined defaulted public bonds and private bank loans.
The Altman–New York University Salomon Center Index of Defaulted Bonds grew to over 200 individual issues and a face value of $56.2 billion; the market value was only $11.8 billion. The market–to–face value ratio of the Bond Index grew somewhat to 0.21 from 0.15 one year ago, but remained at a relatively low figure. The face value of our Defaulted Bank Loan Index also grew to $44.7 billion and the market–to–face value ratio remained quite low at 0.53.
The recovery rate on defaulted bonds (price just after default) was very low at 25 cents on the dollar; likewise, the bank loan recovery rate in 2001 was also relatively low at 55 cents on the dollar. With new defaulted bonds rising in 2001 to a record $63.6 billion (default rate of 9.80 per cent) and the default outlook for 2002 high investment opportunities should abound in the distressed debt market.
Indications are that distressed investors (both old and new) are successfully raising funds because investor expectations are buoyant.

Information technology,efficiency and productivity: evidence from Korean local governments

This study evaluates the performance of Korean local government by measuring their technical efficiency (TE) and total factor productivity (TFP) growth and, more importantly, examining the impact of information technology (IT) on this performance. The study is different from received analysis in that a unique measure of the state of IT–the Informatization Index–is used to investigate the impact of IT on both TE and TFP growth. Empirical analyses are conducted on data from 222 Korean local governments for the period 1999 to 2001. In particular, data envelopment analysis techniques are applied to calculate TE scores and TFP growth rates for sampled local governments. The empirical findings confirm the positive impact IT has in improving technical efficiency and accelerating productivity growth. The estimated coefficients are correctly signed (with other regional characteristics controlled for) when TE scores and TFP growth rates are regressed on the Index. In addition, the findings indicate that economies of density are present in the production of local public services.     

Exploring Duopoly Markets with Conjectural Variations

In this article, the authors investigate competitive firm behaviors in a two-firm environment assuming linear cost and demand functions. By introducing conjectural variations, they capture the different market structures as specific configurations of a more general model. Conjectural variations are based on the assumption that each firm believes its own strategy influences its rival's strategy. Firms derive their optimal choice from these exogenous conjectures, under the form of a conjectural best-response function. The authors’ approach fully encompasses the standard measures of market power (the Lerner Index) and concentration (the Herfindahl Index), both depending on the conjectural variations. They finally represent, analytically and graphically, the equilibrium strategies and the associated indexes in a unified framework for any level of competition, ranging from perfect competition to collusion.
