Communication management during risk events and crises in a globalised world: Predictability of domestic media attention for calamities

While governments are concerned with controlling domestic safety issues and preventing resulting potential societal disruptions, events abroad can trigger similar effects. Globalisation magnifies the media attention for events, domestic and abroad, which poses new challenges for authorities. This paper suggests additional approaches for governments to address such situations. Based on interviews with experts and representatives of authorities and analysis of Dutch media attention for external safety events, this paper identifies criteria that can predict media attention and factors that may contribute to effective policy responses. Both can contribute to help to manage external safety risk events. The study shows that media response is predictable to a certain extent. This insight can be a tool in the wider range of measures for authorities to help manage a crisis situation and in particular strategies to cope with the media.     

Dependence and risk spillovers among clean cryptocurrencies prices and media environmental attention

This paper examines the relationships among cryptocurrency environmental attention and clean cryptocurrencies prices using Time-Varying Parameter Vector Auto-Regression (TVP-VAR) and wavelets techniques. Results show strong connectedness among these variables, implying that the prices of clean cryptocurrencies are influenced by attention on cryptocurrency sustainability. Connectedness is stronger with positive shocks on environmental attention than negative shocks. Also, in the short-term, clean cryptocurrencies prices lead environmental attention, especially after 2021. However, there are notable periods when environmental attention led clean cryptocurrency prices before 2021. In the long-term, clean cryptocurrencies such as Hedera, Polygon, Cosmos, IOTA, TRON, Stellar, Tezos and Ripple lead environmental attention. In the presence of bitcoin, the degrees of connectedness increased across both shocks on cryptocurrency environmental attention. In all cases, the bitcoin market is the main destination of shocks from the system. We highlight some crucial implications of these results.

Retail investor attention and corporate innovation in the big data era

This paper explores the corporate governance role of retail investor attention from the perspective of corporate innovation. Using a sample of Chinese listed firms from 2011 to 2019, we find that retail investor attention significantly promotes corporate innovation. Thisresult ise robust to a series of robustness checks to address potential endogeneity concerns. I further conclude that the impact of retail investor attention on corporate innovation is mainly through alleviating a firm's financial constraints and deterring agency costs. In addition, such effects are more pronounced in firms with higher media and analyst coverage as well as those with more overconfident CEOs. The results provide empirical evidence of the corporate governance function of individual investors in the current digital era.     

投资者关注度与股票市场——以PM2.5概念股为例

近年来雾霾成为中国社会的热点话题,而雾霾频发导致PM2.5概念股受到投资者广泛的关注。本文结合现实环境问题,研究投资者通过对环境的关注度继而对与环境相关的股票的影响。具体而言,本文探究投资者对雾霾和PM2.5概念股的关注度对PM2.5概念股的影响。分析发现投资者对雾霾和PM2.5概念股的关注度的增加能拉升PM2.5概念股的股价。投资者对雾霾的关注度和PM2.5概念股的收益率显著正相关。关注度的增加同时也提高PM2.5概念股交易的活跃程度以及PM2.5概念股涨停的可能性。此外,本文发现正面的新闻报道会拉升PM2.5概念股的股价而负面的新闻报道会降低其股价。最后,本文通过讨论内生性和异质性等一系列稳健性检验进一步验证上述结论。

Can Companies Influence Investor Behaviour through Advertising? Super Bowl Commercials and Stock Returns

Recent research shows that mood and attention may affect investors’ choices. In this paper we examine whether companies can create such mood and attention effects through advertising. We choose a natural experiment by investigating price reactions and trading activity for firms employing TV commercials in 19 Super Bowl broadcasts over the 1969–2001 period. We find significant positive abnormal returns for firms which are readily identifiable from the ad contents, which is consistent with the presence of mood and attention effects. For recognisable companies with the number of ads greater than the sample mean, the event is followed by an average abnormal one day return of 45 basis points. The effect appears to persist in the short term with the 20‐day post‐event cumulative abnormal returns for such firms averaging 2%. We find significant abnormal net buying activity for small trades in shares of recognised Super Bowl advertisers indicating that small investors tend to be the ones most attracted by the increased publicity.     

Fighting de-industrialisation: The role of local government social audits

The aim of this paper is to focus attention on local government (local authorities) as an increasingly important user group of corporate information. An initial assessment of their information needs is made, based upon an analysis of recent notable attempts at social cost analysis performed by U.K. local authorities, which seek to measure the social and economic impact of plant closure decisions on communities they serve. The paper concludes by taking some tentative first steps towards establishing a normative framework for such analysis.     

A risk perspective supporting organizational efforts for achieving high reliability

Many industries and organizations are actively searching for approaches that can help them enhance the reliability of their operations and avoid mishaps. The concept of high reliability organizations (HROs) has been given considerable attention in this regard. HRO theorists have emphasized the process of mindfulness as a characteristic that allows for better interaction with risk and uncertainty, in order to minimize the potential for failures. From a risk management perspective however, it is not straightforward how to best proceed to obtain a mindful infrastructure which enables such capabilities. Various perspectives on risk and uncertainties exist, which call for different approaches and solutions. A key question studied in this paper is to what extent are traditional risk perspectives based on probability and historical data limited in their ability to support an HRO mindset for managing risk. The main purpose of the paper is to draw attention to an alternative risk perspective that replaces probability with uncertainty in the definition of risk, and to show how such a risk perspective can better support the implementation of HRO theory than the more traditional perspectives. We discuss the implications of such a shift in thinking – from focusing on probabilities to the broader domain of uncertainties regarding risk – for organizations that are seeking to improve their risk management capabilities and enhance the reliability of their operations.

证券分析师利益冲突影响投资者利益吗——一个经验研究评述(1995—2007)

近年来,公众对证券分析师利益冲突的广泛关注促使政府及相关部门采取了组织隔离与业务分立等一系列监管措施以保护投资者利益。然而,近期的实证研究却对证券分析师利益冲突损害投资者利益这一监管前提提出了质疑。本文在对1995—2007年间相关文献进行综述的基础上,分析了实证结果与监管当局观点之间存在差异的原因,并据此提出了若干利益冲突监管政策调整思路,以期为我国证券市场监管效率的提高提供启示和借鉴。

流动性约束视角下我国房价财富效应与最优利率规则研究

后危机时代中国房价的波动引起了广泛关注,如何利用以货币政策为代表的宏观调控抑制高房价透支未来经济发展的程度,成为当前管理层高度关注的焦点。本文建立了新凯恩斯模型框架分析房价波动如何通过流动性约束影响消费,从而揭示了中央银行货币政策与房价的财富效应之间的关系,得出最优利率规则中房价的最优权重随预期通胀、产出缺口、房价和名义利率而变动的结论。通过实证分析本文进而认为,利率规则比货币供应量更能迅速调控房价的增长和居民消费的扩张。中国房价上涨的财富效应虽然比较明显,但流动性约束的作用机制需要一个过程才能显现,利率调控的效果也有一个量变到质变的过程,从而在理论上为中央银行制定应对房价的利率政策提供了一定启示。
