The purpose of this paper is to analyze the wealth effect of involuntary delisting and investigate insider opportunism and the role of corporate governance, liquidity and legal environment in involuntary delisting in Japan’s stock market.

The authors use a sample of 136 involuntarily delisted firms in Japan’s stock markets between 2002 and 2012. The authors examine ownership changes of inside shareholders prior to delisting and estimate regression models for the wealth effect of involuntary delisting.

Involuntary delisting is highly disruptive in Japan, and limited liquidity of delisted stocks appears to be an important cause. However, the ownership reduction of inside shareholders before delisting is limited, totaling 2–3 percent. For delisted firms with an insider bank, the decrease in share price leading up to a delisting announcement is much less, while the decrease in share price upon a delisting announcement is far greater.

The study investigates involuntary delisting in regard to the opportunistic behavior of inside shareholders and the role of institutional environment in Japan’s stock market. Insiders, especially insider banks, maintain ownership in a distressful context leading to the forcible delisting of a distressed firm. The authors find some evidence that suggests that the market believes the insider bank will try to prevent the ailing firm’s insolvency. The findings are consistent with the implicit relational contracts that characterize Japanese firms.

The purpose of this paper is to investigate whether there is any difference across individual investors, domestic and foreign institutional investors in trading volume responses to analyst reports. The authors also examine the determinants of trading volume responses using firm as well as forecast characteristics.

The authors use trading data from the Korean equity market. The authors divide investors into three classes of investors; namely, individual investors, domestic institutional investors, and foreign institutional investors. The authors then examine whether the trading responses to analyst reports vary across investor types, and how firm characteristics and characteristics of analyst reports influence the trading activities on the release dates across investor types.

Individual investors are the most responsive investor group, being responsive to analyst reports on small, neglected firms with large inside ownership as well as to analyst reports with optimistic forecasts. Domestic institutional investors are responsive to reports on neglected firms with high return volatility while foreign institutional investors show least responses.

There are few studies that investigate whether the trading responses to analyst reports vary across investor types and how firm characteristics and characteristics of analyst reports influence the trading activities on the release dates across investor types. Taking advantage of the trading volume data for the three main investor types in the Korean stock market, the authors study the trading volume responses for each investor type and make comparisons across investor types.

Existing studies show that firms may have an incentive to use share repurchases opportunistically, thereby taking advantage of market participants’ confirmation bias that share repurchase is a signal of undervaluation. This study aims to investigate whether signaling costs and accounting transparency can serve as tools to identify opportunistic share repurchases.

The authors measure signaling costs by using two share repurchase methods (direct and indirect share repurchase) with different share repurchase costs, and measure accounting transparency using the history of earnings timeliness. The authors further measure long-term performance following share repurchases using operating performance and stock returns. Lastly, the authors compare the long-term performances between the groups defined by share repurchase method and earnings timeliness level.

The authors find that indirect share repurchase firms with a history of poor earnings timeliness experience unfavorable long-term performance, while other share repurchase firms do not. This finding reinforces the view that some share repurchases may be driven by managerial opportunism. In particular, when firms with a history of poor earnings-reporting behavior choose a low-cost repurchase method, their share repurchases may be motivated by managerial opportunism.

The findings suggest that past earnings timeliness and the signaling costs of a repurchase together are useful predictors of false signaling. Moreover, they suggest that investors can – at least in part – predict opportunistic share repurchases by using signaling costs and accounting transparency.

This study examines acquirers' earnings management in intragroup mergers to investigate whether stock-for-stock mergers between affiliated firms within the same family-controlled business group facilitate the controlling shareholder's rent seeking. Specifically, it investigates the acquiring firm's incentive to inflate premerger-announcement earnings in intragroup mergers given the controlling shareholder's relative equity holdings in the target and acquiring firms. The authors also examine how creditor monitoring affects premerger-announcement earnings in intragroup mergers compared to mergers between independent firms.

Using univariate analysis, panel regression based on accruals and cross-sectional regression based on discretionary accruals, the authors compare earnings management in mergers between affiliated firms with that in mergers between independent firms in the context of Korean business groups. The authors also compare the effects of creditors on earnings management in both cases.

Acquirers' premerger-announcement positive abnormal accruals are less evident in mergers between affiliated firms than in mergers between independent firms. These accruals decrease with high financial leverage only in the latter case, suggesting that creditor monitoring mitigates earnings management only in independent firm mergers.

The authors examine intragroup mergers, unlike previous studies, which focus on unaffiliated firm mergers. They also contribute to the literature on stock-for-stock mergers, showing that lender monitoring can mitigate the acquiring firm's premerger earnings management in unaffiliated firm mergers but not in intragroup mergers. These findings suggest that stock-for-stock mergers between affiliated firms may facilitate the controlling shareholders' rent seeking, which has policy implications for emerging markets with large family-controlled business groups.

The purpose of this article is to review the consumer behavior and social network theory literature related to the online and e-commerce context.

To conduct the review, the authors draw on a sample of 942 articles published from 1993 to 2012 addressing consumer behavior or social network issues in the online or social media context. The sample is analyzed by both era (incubation, expansion and explosion) and primary topic.

Eight categories of online consumer behavior research are described. In the order from largest to smallest, these are: cognitive issues, user-generated content, Internet demographics and segmentation, online usage, cross cultural, online communities and networks, strategic use and outcomes and consumer Internet search.

The literature has been summarized in each category and research opportunities have been offered for consumer behavior and social network scholars interested in exploring the online context.

The purpose of this paper is to examine how various characteristics of brand posts influence online engagement on Facebook brand pages.

The data used for this study were obtained from the posts of ten popular official brand pages. For the selected period between March 1 and May 1, 2014, a total of 1,030 posts were obtained and manually processed on September 1, 2014. To assign post categories to the posts created by page administrators, the authors performed manual coding, following the coding development strategy.

The results demonstrated that the media and content type of posts exert a significant effect on user online engagement. This study used liking, commenting and sharing behavior as a measure of users’ online engagement to specify the new phenomena.

The findings are relevant for the theory of information dissemination and provide valuable and directly applicable implications for the social media marketing of companies.

The current study extends the investigation into online relationship building by examining how Eurozone companies belonging to the EURO STOXX 600 index use the popular video platform YouTube to facilitate dialogic communication with their stakeholders. The purpose of this paper is to analyse the extent and main purposes of the channel's usage, the companies’ activities and online practices, as well as the factors on this platform influencing the channel's activity, the audience, and the stakeholders’ engagement.

To achieve this goal a sample of 306 Eurozone companies listed in the STOXX Europe 600 index, including 19 subsectors and 12 countries, have been analysed. Stakeholder and dialogic theory were applied as a theoretical background for this study.

The results indicated that 44 per cent of companies studied have an official YouTube channel, which is mostly used for promotional purposes. It was found that the size of the company, the sector, and its country of origin determine YouTube channel activity, and that higher activity leads to a higher number of subscribers, thus fostering an initial step to better stakeholder engagement.

Given that this is the first study of its kind to provide this type of analysis, the resulting unique contributions may provide value to the information systems field and also contribute to the advancement of information systems research.

The authors aimed to develop environmentally stable NIR‐absorbing windows by blending a near‐infrared (NIR)‐absorbing dye and a photo‐crosslinkable polymer.

To prepare an environmentally stable NIR‐absorbing window, a NIR‐absorbing dye was mixed with crosslinkable poly(vinyl cinnamate) (PVCn). The crosslinking of PVCn was carried out by photo‐dimerisation reaction of cinnamate with UV‐exposure at a wavelength of 254 nm for 4 min.

The resistance of the photo‐crosslinked hybrid films against humidity, heat, and ultraviolet radiation damage was improved dramatically relative to the pristine NIR‐absorbing dye. These improvements result from the protection of NIR‐absorbing dye to moisture exposure in the presence of the polymer network.

The simple and practical method resulted in a dramatic improvement in the environmental stability of NIR‐absorbing window.

To encourage buyers to contribute product reviews, some online sellers offer monetary rewards. The purpose of this paper is to investigate the impact of monetary rewards on buyers’ purchase decisions and review contributions, as well as the impact on the seller’s price decisions and profit.

The authors consider an online seller in a two-stage setting. Prior to Stage 1, the profit-maximizing seller sets the price and decides whether to offer a monetary reward secretly to motivate online reviews. Then, a continuum of buyers arrives and makes purchase decisions at the beginning of each stage. First-stage buyers may contribute reviews if they are satisfied, which will affect demand in the second stage. Using this analytical framework, the authors analyze the impact of monetary rewards.

If the monetary reward is small, it decreases the seller’s profit and fails to generate more reviews. It also increases price, leading to a decline in total demand. Thus, when the reward is lower than a certain threshold, all buyers are worse off. Only when the reward exceeds the threshold are buyers who contribute reviews better off. Profit and total demand both increase in review quality, while the price may either increase or decrease in it.

To the best of the authors’ knowledge, this paper is the first to analyze theoretically the impact of monetary rewards on buyers’ purchase decisions, review contributions and on online sellers’ decisions.
