The impact of individual investor trading on information asymmetry in the Korean stock market

This paper examines the impact of individual investor trading on information asymmetry in the market. In particular, we examine the relationship between the trading volume by individual investors and the corresponding bid-ask spread in the Korean stock market, where the majority of the trading activity is driven by individual investors and therefore information asymmetry can be evident. We find that high trading activity by individual investors increases the bid-ask spread in a short investment horizon, suggesting that individual investors, as uninformed and unsophisticated traders, amplify the degree of information asymmetry in the market through trading.     

Research on entropy generation strategy and its application in carbon trading market

The study seeks to provide a deeper insight and strategies into the carbon trading market, the internal mechanism, and the linkage mechanism for emission reduction in the carbon trading market right from its inception. The study differs from most prior research on carbon trading, as this current paper incorporates the carbon market with the dissipative structure theory. Based on the dissipative structure theory, this study adapts the entropy generation principle as the base for the carbon trading market. The study captures the following key dimensions: the change of carbon market value, the entropy generation principle of carbon quota trading process, and the replacement process involved in production factors in carbon trading. The study revealed that the entropy generation of the carbon trading market is mainly caused by the cost gradient formed as a result of the cost difference of emission reduction and the increase of production factor input required by economic development. Moreover, the study revealed clearly the dynamics of the entropy index and the carbon market emission reduction efficiency. Thus, the lower the entropy value of the carbon market, the higher the emission reduction efficiency.     

Intraurban residential mobility: The role of transactions costs, market imperfections, and household disequilibrium

This paper presents a model of household residential search and mobility that focuses on microeconomic elements of household behavior and incorporates housing market features. The model is cast explicitly in terms of a rigorous model of housing demand, allowing the benefits from moving to be measured as the compensating income variation of the potential change in consumption. The empirical results indicate that large changes in economic variables, such as income and prices produce only small potential gains from moving and that a major factor in the moving decision is the magnitude of search and moving costs.     

The dynamics of Central European equity market comovements

This paper examines short-term and long-term comovements between developed European Union (EU) stock markets and those of three Central European (CE) countries which recently joined the EU. Dynamic cointegration and principal components methods are applied, in addition to static tests. While we find no evidence of cointegration for the period July 1995–February 2005 as a whole, dynamic tests reveal alternating period of cointegration disrupted by episodes dominated by short-term domestic factors. Principal components analysis reveals that a stable factor explains a large proportion of return variances. Ultimately, despite the decade-long process of alignment by CE countries with the EU, evidence of steadily increasing convergence of equity markets is lacking.     

The 1986 Tax Reform Act and ex-dividend day price and volume patterns: Evidence from organized exchanges and the OTC market

By effectively removing the differential taxation of dividends and capital gains, the 1986 Tax Reform Act provides a unique opportunity to re-examine the “tax induced clientele” explanation of ex-dividend day price behavior. The analysis indicates an increased preference for dividends and provides evidence of significant abnormal volume during the ex-dividend period, consistent with dividend induced trading activity. In addition, the level of dividend preference is found to be far greater on the organized exchanges than in OTC trading.     

Forecasting the Chinese stock market volatility with international market volatilities: The role of regime switching

The purpose of this paper is to investigate the role of regime switching in the prediction of the Chinese stock market volatility with international market volatilities. Our work is based on the heterogeneous autoregressive (HAR) model and we further extend this simple benchmark model by incorporating an individual volatility measure from 27 international stock markets. The in-sample estimation results show that the transition probabilities are significant and the high volatility regime exhibits substantially higher volatility level than the low volatility regime. The out-of-sample forecasting results based on the Diebold-Mariano (DM) test suggest that the regime switching models consistently outperform their original counterparts with respect to not only the HAR and its extended models but also the five used combination approaches. In addition to point accuracy, the regime switching models also exhibit substantially higher directional accuracy. Furthermore, compared to time-varying parameter, Markov regime switching is found to be a more efficient way to process the volatility information in the changing world. Our results are also robust to alternative evaluation methods, various loss functions, alternative volatility estimators, various sample periods, and various settings of Markov regime switching. Finally, we provide an extension of forecasting aggregate market volatility on monthly frequency and observe mixed results.     

The role of complementary products on platform adoption: Evidence from the video console market

This paper studies the importance of the interdependences within platform-based markets. Specifically, the work examines the influence of complementary product portfolios on the adoption of platforms by individuals. The study analyzes data from a panel of 17 video game platforms in three regions (the US, Japan and Europe) for the period between 1989 and 2011. The results suggest that platform adoption is driven by the availability and users of complementary products. The study also finds that this impact is stronger when platform providers jointly manage the in-house complementary product portfolio and the platform. These findings reveal that decisions on complementary products act as strategic drivers of adoption in platform-based markets.     

The versatile role of sustainable market entrepreneurs in market transformation: An intervention framework for institutional change

This article investigates in which way sustainable entrepreneurship can generate institutional change that transforms markets towards sustainability. A transformation of models of economic organization and market structures through sustainable entrepreneurship fosters the path towards sustainability. Institutional change involves sustainable market entrepreneurs as institutional entrepreneurs that operate in an effectual manner in different market transformation phases. Sustainable market entrepreneurs while seeking entrepreneurial opportunities simultaneously shape existing market structures and market conditions in different sustainable market transformation phases thereby creating new opportunities. Accordingly, a framework that explains institutional change prompted by sustainable market entrepreneurs in market transformation phases is developed. In this framework, various interventions which encourage sustainable market entrepreneurs to co-create with the stakeholders of their choice are strategized. The provided framework enhances the understanding of the versatile role of sustainable market entrepreneurs and potentially the leverage of their actions towards institutional impact over time.     

The impact of option listing on the price volatility and trading volume of underlying OTC stocks

This paper examines the impact of an initial option listing on the price volatility and trading volume of underlying OTC stocks. The sample is divided by market value to determine whether larger firms are impacted differently by option listing than smaller firms. We find relative trading volume increases significantly, with the small and medium market value firms showing the largest gain. However, the tests show no evidence of changes in price volatility following option listing. No significant changes were found in either the firms' betas or variance following option initiation. The results provide further evidence that option listing does not destabilize the market for the underlying stock.     

The role of state ownership and institutions in the innovation performance of emerging market enterprises: Evidence from China

Although it has been suggested that institutional context influences a firm's innovation performance, the role of regulatory institutions has been underexplored. Extending previous research, this study investigates whether and how regulatory institutions (i.e. state ownership, region-specific marketization and industry-specific institutional policy) affect innovation performance of emerging market enterprises (EMEs). Evidence derived from a large sample of Chinese manufacturing firms demonstrates that state ownership positively moderates the effect of R&D intensity on innovation performance. However, state ownership is not equally beneficial for all firms. Our analysis shows that region-specific marketization and industry-specific institutional policy enhance the innovation-enhancing effect of state ownership. By revealing the role of regulatory institutions, our study points to the importance of looking beyond firm boundaries to understand why EMEs are able to innovate despite their weak internal capabilities.     

The role of the market in transforming training and knowledge to superior performance: evidence from the Australian manufacturing sector

Training and development of employees increases the value and breadth of employee capabilities and knowledge, although this improvement, we suggest, cannot drive improved competitive performance in the absence of effective commercialisation of these capabilities. We propose and test a model of training and organisational performance, mediated by effective market engagement and transformation by firms. We find, as we anticipate, no direct link between training and performance, although there is a significant and positive path between training and performance when mediated through effective and contemporaneous market engagement.     

Evolving United States stock market volatility: The role of conventional and unconventional monetary policies

Despite the econometric advances of the last 30 years, the effects of monetary policy stance during the boom and busts of the stock market are not clearly defined. In this paper, we use a structural heterogeneous vector autoregressive (SHVAR) model with identified structural breaks to analyse the impact of both conventional and unconventional monetary policies on U.S. stock market volatility. We find that contractionary monetary policy enhances stock market volatility, but the importance of monetary policy shocks in explaining volatility evolves across different regimes and is relative to supply shocks (and shocks to volatility itself). In comparison to business cycle fluctuations, monetary policy shocks explain a greater fraction of the variance of stock market volatility at shorter horizons, as in medium to longer horizons. Our basic findings of a positive impact of monetary policy on equity market volatility (being relatively stronger during calmer stock market periods) are also corroborated by analyses conducted at the daily frequency based on an augmented heterogeneous autoregressive model of realised volatility (HAR-RV) and a multivariate k-th order nonparametric causality-in-quantiles framework. Our results have important implications both for investors and policymakers.     

The role of fiscal policies for external imbalances: Evidence from the European Union

We revisit the relation between budget deficits and current account deficits for 28 European Union countries from 1996 to 2019. We find that an increase in budget deficit of 1 pp of GDP results in a deterioration of the current account deficit of 0.318 pp of GDP, which supports the Twin Deficits Hypothesis. On the other hand, dynamic panel estimates partially corroborate the Ricardian Equivalence Hypothesis in the presence of a fiscal rules index. In addition: i) the relation between the two deficits is asymmetric and the negative impact of the recent Eurozone banking and sovereign debt crisis on the current account balance is observed; ii) with right-wing governments, the impact of the budget balance on the current account balance is mitigated; if the government is on the left, the impact of the budget balance on the current account balance is amplified; iii) after 2010, the budget balance positively affects the current account balance; and iv) the positive impact of the budget balance on the current account balance is higher in the cases of non-Eurozone countries, high budget deficit countries, and low exports countries, whereas it is lower in the cases of Eurozone countries, low budget deficit countries, and high exports countries.     

Environmental proactivity,competitive strategy,and market performance: The mediating role of environmental reputation

This article examines the impact of small and medium-sized enterprises' (SMEs) proactive environmental strategy on market performance through the mediating mechanism of environmental reputation. In addition, we investigate the potential moderating role of competitive strategies on the environmental reputation-market performance nexus. Data were collected from 223 SMEs. Using the hierarchical multiple regression analysis, the results show that a proactive environmental strategy positively enhances environmental reputation. Also, the influence of proactively environmental strategy on market performance is mediated by environmental reputation. In addition, our findings show the relationship between environmental reputation and market performance is greater for firms that adopt the differentiation strategy but not significant for firms adopting the low-cost and integrated strategies. Our study offers several theoretical and practical implications.     

SFAS 133 and income smoothing via discretionary accruals: The role of hedge effectiveness and market volatility

This study investigates whether the Statement of Financial Accounting Standard No. 133 (SFAS 133) influences firms’ income smoothing via discretionary accruals decisions. Moreover, we investigate whether the level of hedge effectiveness and market volatility affects the impact of SFAS 133 on firms’ income smoothing via discretionary accruals decisions. Consistent with our predictions, we find a significant increase in income smoothing via discretionary accruals activity after the adoption of SFAS 133. We also find that income smoothing via discretionary accruals after the adoption of SFAS 133 increases with the level of hedge ineffectiveness. By contrast, we find that perfect hedgers do not engage in more income smoothing via discretionary accruals after the adoption of SFAS 133. Finally, we find that the higher the market volatility is the larger the income smoothing is via discretionary accruals after the adoption of SFAS 133. This implies that higher market volatility makes it more difficult for firms to meet hedge accounting requirements, thereby increasing unmanaged earnings volatility and income smoothing. Prior studies suggest that regulators are expressing concern about the effect of earnings management on the quality of reported earnings and the functioning of capital markets (e.g., Barton, 2001 ). In this regard, our findings imply that accounting standard setters should take into account the trade‐off between transparency and income smoothing.     

Green bonds,sustainable development and environmental policy in the European Union carbon market

This study assesses the non-linear effects of green bonds, conventional bonds and energy commodities on the behaviour of the cap-and-trade European Union carbon market (European Union Emissions Trading System [EU-ETS]). By estimating four models, using Markov-switching (MS) econometric methodology, non-linearities are confirmed in dynamic behaviours, observing in the global calculation a positive effect of green bonds (S&P Green and Sol Green) on the carbon market, in regimes of both high and low volatility, whereas conventional bonds (S&P Agg) and energy commodities (DJCI En) contribute to a decrease in the carbon market in regimes of high volatility. The relevance of green bonds is underlined in determining the behaviour of the carbon market, besides observing greater persistence of the low volatility regime. These results allow both investors and fund managers to implement strategies in different volatility or economic activity contexts through a diversified portfolio and green/climate structure.     

Price gap anomaly in the US stock market: The whole story

This paper analyses the price gap anomaly in the US stock market (comprised of the DJI, S&P 500 and NASDAQ) covering the period 1928 to 2018. This paper aims to investigate whether or not price gaps create market inefficiencies. Price gaps occur when the current day’s opening price is different from the previous day’s closing price due orders placed before the opening of the market. Several hypotheses are tested using various statistical tests (Student’s t-test, ANOVA, Mann-Whitney test), regression analysis, and special methods, that is, the modified cumulative returns and the trading simulation approaches. We find strong evidence in favour of abnormal price movements after price gaps. We observe that during a gap day prices tend to change in the direction of the gap. A trading strategy based on this anomaly was efficient in that its results were not random, indicating that this market was not efficient. The momentum effect was found to be temporary and no evidence of seasonality in price gaps was found. Lastly, our results were also contrary to the myth that price gaps tend to get filled.     

Asymmetric information and inside management trading in the Chinese market

Insider trading incentives have been widely examined in stock markets, but mainly in developed countries. Given the fact that the volatility of stock exchange markets in emerging economies is typically even higher, there is a need for research to explore the extent to which information asymmetry plays a role in management trading incentives in emerging economies. To address this research need, this study examines management trading incentives in relation to investment efficiency in Chinese listed firms on the main board and on the small- to medium-enterprises (SME) board in the period 2006 to 2017. We find that executives buy shares when firms’ investments are more efficient. The frequency of management buying also increases with investment efficiency. However, managers do not sell their shares according to firms’ investment efficiency. Moreover, executives of firms listed on the main board trade more on the asymmetric information of investment efficiency than those on the SME board.

Efficient predictability of stock return volatility: The role of stock market implied volatility

This study examines the predictability of stock market implied volatility on stock volatility in five developed economies (the US, Japan, Germany, France, and the UK) using monthly volatility data for the period 2000 to 2017. We utilize a simple linear autoregressive model to capture predictive relationships between stock market implied volatility and stock volatility. Our in-sample results show there exists very significant Granger causality from stock market implied volatility to stock volatility. The out-of-sample results also indicate that stock market implied volatility is significantly more powerful for stock volatility than the oil price volatility in five developed economies.
