Purpose: This study attempted to examine the risk of stock price plunge according to the firm's management strategy. Prospector firms value innovation and have high uncertainties due to rapid growth. There is a possibility of lowering the quality of financial reporting in order to meet market expectations while withstanding the uncertainty of the results. In addition, managers of prospector firms enter into compensation contracts based on stock prices, thus creating an incentive to withhold negative information disclosure to the market. Prospector firms' information opacity and delays in disclosure of negative information are likely to cause a sharp decline in share prices in the future. Research design, data and methodology: This study performed logistic analysis of KOSPI listed firms from 2014 to 2017. The independent variable is the strategic index, and is calculated by considering the six characteristics (R&D investment, efficiency, growth potential, marketing, organizational stability, capital intensity) of the firm. The higher the total score, the more it is a firm that takes a prospector strategy, and the lower the total score, the more it is a firm that pursues a defender strategy. In the case of the dependent variable, a value of 1 was assigned when there was a week that experienced a sharp decline in stock prices, and 0 when it was not. Results: It was found that the more firms adopting the prospector strategy, the higher the risk of a sharp decline in the stock price. This is interpreted as the reason that firms pursuing a prospector strategy do not disclose negative information by being conscious of market investors while carrying out venture projects. In other words, compensation contracts based on uncertainty in the outcome of prospector firms and stock prices increase the opacity of information and are likely to cause a sharp decline in share prices. Conclusions: This study's analysis of the impact of management strategy on the stock price plunge suggests that investors need to consider the strategy that firms take in allocating resources. Firms need to be cautious in examining the impact of a particular strategy on the capital markets and implementing that strategy.

English contract law has traditionally taken the view that it is not the duty of the parties to a contract to give information voluntarily to each other. In English law, one of the principal distinctions between insurance contract law and general contract law is the existence of the duty of disclosure in insurance law. This article is, therefore, designed to analyse the scope or extent of the duty of disclosure and the remedy for breach of the duty in English marine insurance law. The main purpose of this article is also to seek the alternative remedy for the breach. The results of analysis are as following : First, the scope of the duty of disclosure is closely related to the test of materiality and the concept of a hypothetical prudent insurer. The assured is required to disclose only material circumstances subject to MIA 1906, s. 18(1). The test of materiality, which had caused a great deal of debate in English courts over 30 years, was finally settled by the House of Lords in Pan Atlantic and the House of Lords rejected the 'decisive influence' test and the 'increased risk' test, and the decision of the House of Lords is thought to accept the 'mere influence' test in subsequent case by the Court of Appeal. Secondly, an actual insurer is, in order to avoid contract, required to provide proof that he is induced to enter into the contract by reason of the non-disclosure of the assured. But this subjective test of actual inducement is somewhat meaningless in sense that English court takes the test of materiality as a starting point and assumes the presumption of inducement even in case of no clear proof on the inducement. Finally, MIA 1906, s. 18 provides expressly for the remedy of avoidance of the contract for breach of the duty of disclosure. This means rescission or retrospective avoidance of the entire contract, and the remedy is based upon a fairly crude 'all-or-nothing' approach. The remedy of rescission is too draconian from the point of view of the assured, because he can be deprived of all cover despite he is innocent perfectly. An inadvertent breach from an innocent mistake is as fatal as wilful concealment. What is, therefore, needed in English marine insurance law with respect to remedy for the breach is to introduce a more sophisticated or proportionate remedy ascertaining degrees of fault.

The purpose of this research is to examine the impact of information risk on the Cost of Equity (COE) and whether the risk of a stock price crash mediates the relation between information risk and COE. To test the dynamic nature of the proposed model, the two-step system GMM dynamic panel estimators are applied to all the non-financial firms listed on the Pakistan Stock Exchange (PSX) from 2007- 2018. The results of this study show that all three types of information risk, as well as the risk of the share price crash, increases the COE. The crash risk strengthens the impact of information risk on the COE. Moreover, these three information risks are correlated with each other and an increase in information quality reduces the effect of asymmetric information and improves the investor interpreting ability, while an increase in private information decreases the transparency. The finding is crucial for asset pricing, portfolio management, and information disclosure. This study contributes to the literature by providing novel findings on the impact of three different types of information risk, i.e. private information, quality of information, and transparency of information on the COE as well as whether crash risk mediates the relationship.

최근 프라이버시 분야에서는 태도와 행동의 일관성 가정을 토대로 진행되어온 기존의 프라이버시 연구를 부정하고, 프라이버시 태도가 더 이상 행동에 영향을 미치지 않는다고 주장하는 프라이버시 역설 관점의 연구가 점점 증가하고 있는 추세이다. 본 연구에서는 정보제공의도와 정보제공행동 간의 관계에서 프라이버시 역설 현상이 실제로 존재하는지 확인하고, 왜 이러한 현상이 나타나는지 행동경제학에서 논의되는 이중 프로세스 이론을 통해 설명하고자 하였다. 실증분석 결과, 정보제공의도와 정보제공행동 간에는 통계적으로 유의한 차이가 있는 것으로 나타나 프라이버시 역설의 존재가 확인되었다. 다음으로, 프라이버시 위험은 합리적 사고에 의해 지배되는 프라이버시 의사결정의 결과인 정보제공의도에, 프라이버시 신뢰는 직관적 사고에 의해 지배되는 실제 교환관계의 결과인 정보제공행동에 영향을 미치는 것으로 분석되어 이들이 상황에 따라 차별적 역할을 한다는 것이 확인되었다.

These days, corporate risk management has become a major concern in the corporate world. Companies in the global environment are exposed to diverse kinds of risks that are affecting the decisions of investors and other stakeholders. Therefore, companies are expected to not only identify and manage risks but also voluntarily report the same to the stakeholders. Increasingly, standard setters and regulators are requiring firms to disclose such information. On the contrary, there also exists a perception that risk reporting can create a negative impression among the stakeholders about the future of the company. In line with such growing dilemma for risk disclosures, the issue of corporate risk reporting (CRR) has been receiving immense emphasis from the accounting academicians. The main objective of this article is to conduct a comprehensive literature review on corporate risk disclosures. In order to fulfill this objective, at first, a summary of the relevant available literature is presented to identify the current regulations on risk reporting, existing trends of CRR research and theories applied in research. Then, through analysis, several research avenues are identified. It is expected that if these dimensions are explored by the future researchers, a better and broader understanding of the risk reporting practices can be achieved.

There has recently been a surge of interest in relational database mining that aims to discover useful patterns across multiple interlinked database relations. It is crucial for a learning algorithm to explore the multiple inter-connected relations so that important attributes are not excluded when mining such relational repositories. However, from a data privacy perspective, it becomes difficult to identify all possible relationships between attributes from the different relations, considering a complex database schema. That is, seemingly harmless attributes may be linked to confidential information, leading to data leaks when building a model. Thus, we are at risk of disclosing unwanted knowledge when publishing the results of a data mining exercise. For instance, consider a financial database classification task to determine whether a loan is considered high risk. Suppose that we are aware that the database contains another confidential attribute, such as income level, that should not be divulged. One may thus choose to eliminate, or distort, the income level from the database to prevent potential privacy leakage. However, even after distortion, a learning model against the modified database may accurately determine the income level values. It follows that the database is still unsafe and may be compromised. This paper demonstrates this potential for privacy leakage in multi-relational classification and illustrates how such potential leaks may be detected. We propose a method to generate a ranked list of subschemas that maintains the predictive performance on the class attribute, while limiting the disclosure risk, and predictive accuracy, of confidential attributes. We illustrate and demonstrate the effectiveness of our method against a financial database and an insurance database.

The purpose of this study is to examine how the characteristics of family firms affect stock price crash risk. Prior studies argued that the opacity of information due to agency problem causes a plunge in stock prices. The governance characteristics of family firms can increase information opacity which leads to crash risk. Therefore, this study verifies whether family firms have a high possibility of stock price crash risk. We use a logistic regression model to test the relationship between family firms and stock price crash risk using listed firms listed on the Korean Stock Exchange during the fiscal years 2011 through 2017. The family firm is defined as the case where the controlling shareholder is the chief executive officer or the registered executive. If the controlling shareholder's share is less than 5%, it is not considered a family business. We found that family firms are more likely to experience a plunge in stock prices. This supports the hypothesis of this study that passive information disclosure behavior and information opacity of family firms increase stock price crash risk.

This research investigates the characteristics of the mobile social commerce and explores the moderating effects of perceived risk and price sensitivity. This survey targeted consumers in their 20s to 30s who use mobile social commerce applications. We used 261 questionnaires for the final statistical analysis. Descriptive analysis, factor analysis, reliability analysis, and hierarchical regression analysis were applied in the data analysis. The results are summarized as follows. First, characteristics of mobile social commerce are composed of economics, informativeness, entertainment and promotion. Second, perceived risk (which had a negative effect on purchase intention) had moderating effects between perceived risk and economics or entertainment. Third, price sensitivity (which had a positive effect on purchase intention) had a moderating effect between price sensitivity and promotion. This study contributes to the disclosure of the role of perceived risk and price sensitivity as moderating factors between the characteristics of mobile social commerce and purchase intention. Finally, useful implications (both academic and practical) are provided for fashion retail managers.

The study aims to investigate the relationship between hedging with derivatives and subsequent firm-level stock price crash risk. Our sample consists of KOSPI- and KOSDAQ-listed companies from 2004 to 2014. The total firm-year observation is 4,886. We find that hedging with derivatives is related to greater possibilities of crash risk. The results suggest that the complexity of economic and financial reporting for derivatives may aggravate the company's information opacity, ultimately increasing the crash risk. We contribute to the growing body of literature on hedging with derivatives. Academics and practitioners have debated on whether or not hedging enhances transparency or rather makes the information environment more opaque. Theoretical research on the role of corporate hedging on information environment shows that hedging enhances earnings informativeness. Meanwhile, pieces of anecdotal and empirical evidence show that the economic and financial reporting complexity of derivatives can harm information transparency. Our results shed light on the question of whether and how hedging with derivatives affects information environment by examining the relationship between hedging with derivatives and crash risk. Furthermore, our findings provide useful insights for policymakers and practitioners. Specifically, our results raise a need for a more transparent disclosure on corporate hedging activities with derivatives.
