Aggregate insider trading and market returns: The role of transparency

Using a sample of countries that require timely disclosures of insider trades, I investigate the effect of country‐level institutions that promote transparency on the extent to which aggregate insider trades predict market returns. I find that financial information transparency mitigates the predictive content of aggregate insider trades when markets are more likely to deviate from fundamentals (i.e., during market fads), and when there is greater co‐movement in stock prices. In contrast, there is some evidence that governance and investor protection mitigate the association between aggregate insider trades and future earnings surprises. Hence, holding constant the timely disclosures of insider trades, other capital market institutions play complementary roles in mitigating the informational frictions that give rise to the predictive content of aggregate insider trades.     

中国企业跨国并购的动因--基于制度分析的视角

过去几十年来，国际生产的增长主要是通过跨国并购的模式实现。不过以前的研究主要集中在运用行业和企业层面的因素来探讨FDI的进入模式。邓宁(2009)强调宏观经济变量可以解释FDI，并呼吁进行更多的研究，以提高我们对宏观经济变量影响重要性的认识。在前期研究的基础上，文章采用2006-2012年6534起中国企业并购交易作为样本，分析中国企业跨国并购交易的决定因素。借鉴诺思的制度理论框架，探讨中国和东道国的正式制度与非正式制度对中国企业发起跨国并购可能性的影响。文章研究的重点在于国家宏观经济和投资者保护状况对中国企业进行跨国并购交易的可能性的影响。通过单因素分析和logistic回归分析发现，中国宏观经济的发展和目标企业所处的商业环境越好，越会促进中国企业跨国并购的可能性。实证结果还显示中国对投资者保护强度越大，中国企业进行跨国并购的可能性更小。     

How cultural branding,story-telling,and personification can save the iconic Australian koala

This article addresses the question as to why such a much loved and iconic Australian animal—the koala—has long been headed on a trajectory of extinction; primarily due to a lack of public concern and political will. Despite the affectionate regard in which they are held, koalas remain out of sight and out of mind for most Australians. However, the widely publicized catastrophic Australian bushfire season of 2019–2020 is a rare and illuminating case in which public support for koala welfare was stimulated by significant national and international media attention. The primary problem facing koala conservation was thrown into sharp relief—the need to proactively protect them from human activities destroying their habitat. This article explores how a marketer-lead intervention, employing cultural branding, story-telling, and personification, could potentially motivate the public to apply pressure at all levels of government to proactively protect the koala's habitat and grow their numbers. This solution is grounded in an awareness of several issues likely to impact its success, including: (1) the koala's biology and behavior, (2) uncertainty around koala population numbers, (3) the emergence of the koala as an (inter)national) icon, (4) the Australian 2019–2020 bushfire emergency, (5) postfire complacency, (6) Lewis and other koala stories, (7) acknowledging competing interests, and (8) taking learnings forward. Finally, the proposed campaign centers on forging emotional links between the koala and consumers, which are likely to positively impact consumers' attitudes, information processing and memory functions associated with messages highlighting the need to preserve the koala's habitat.

Payday loans and consumer financial health

The annualized interest rate for a payday loan often exceeds 10 times that of a typical credit card, yet this market grew immensely in the 1990s and 2000s, elevating concerns about the risk payday loans pose to consumers and whether payday lenders target minority neighborhoods. This paper employs individual credit record data, and Census data on payday lender store locations, to assess these concerns. Taking advantage of several state law changes since 2006 and, following previous work, within-state-year differences in access arising from proximity to states that allow payday loans, I find little to no effect of payday loans on credit scores, new delinquencies, or the likelihood of overdrawing credit lines. The analysis also indicates that neighborhood racial composition has little influence on payday lender store locations conditional on income, wealth and demographic characteristics.
