1 Does regulation of defensive tactics with mandatory rules benefit shareholders? Evidence from event studies in China
آیا تنظیم تاکتیک های دفاعی با قوانین اجباری به نفع سهامداران است؟ شواهدی از مطالعات رویدادی در چین-2020
Scholars have long debated whether defensive tactics increase or reduce firm value and how to regulate them. This article conducts event studies to examine the impacts of the regulation of a common defensive tactic in China that requires shareholders to hold shares for a certain period before they can nominate directors (“the holding-period requirement”). The Chinese Securities Investors Service Center (CSISC), which is a quasi-government organization under the charge of the Chinese Securities Regulatory Commission, initiated regulatory actions against this type of defensive tactic claiming that it violates mandatory rules in Chinese corporate law, which caused on average a -0.31% abnormal return to stocks of over two hundred corporations that had adopted similar tactics. The impact of the first event on the sample stocks was statistically significant, suggesting that the defensive tactics were beneficial to firm value and the regulatory decisions had negative impacts on firm value. Corporations with similar defensive tactics also experienced a -0.25% abnormal return on average after the court ruled that this type of defensive tactic violated Chinese corporate law. Evidence suggests that the events had a larger impact on corporations with dispersed ownership structures and small market capitalization. These results suggest that employing mandatory rules to regulate the holding-period requirements in China is likely to harm shareholders’ interests.

2 Taming the blockchain beast? Regulatory implications for the cryptocurrency Market
اهلی کردن جانور بلاکچین ؟ پیامدهای نظارتی برای بازار رمزنگاری -2019
This paper uses a unique dataset of 120 regulatory events from five classes to test the relevance of the regulatory framework for cryptocurrency value. Time-series market-wide estimates and panel estimates for 300 individual coins and tokens show statistically and economically significant impact of anti-money laundering and issuance regulation. Tighter regulation and more active role of government decrease cryptocurrency prices, evidencing that potentially lower risks and wider adoption commonly attributed to the establishment of the regulatory framework do not compensate for respective efficiency and consumer utility losses. The market is generally efficient in reflecting regulatory information in cryptocurrency prices.

3 Political donations and political risk in the UK: Evidence from a closely-fought election
هدیه های سیاسی و خطر سیاسی در انگلیس: شواهدی از یک انتخابات نزدیک به نبرد-2018
UK regulation discourages corporate political donations but is relatively benign in respect of individual donations. Few UK listed companies make political donations but many more company directors do. We use a unique, hand-collected dataset of political donations to examine whether UK corporate political connections are perceived as being created indirectly via directors’ personal donations. Basing our tests on the sensitivity of company returns to opinion polls preceding the 2010 General Election we find that, on average, firms in industries which donate only to the Conservative Party exhibit higher sensitivity to the electoral success of the Conservatives. However, within industries, there is no consistent evidence that the firms which employ directors who make these donations exhibit higher sensitivity than firms which do not. We justify basing our inferences on return sensitivity to polls by confirming that UK domestic political risk, as proxied by opinion poll changes, is priced around General Elections.

4 Detecting abnormal changes in credit default swap spreads using matching-portfolio models
شناسایی تغییرات ناهنجار در گستره های معاملاتی اعتباری پیش فرض با استفاده از مدلهای تطبیق با دارایی-2018
We evaluate the size and power of different statistical tests and adjustment methods for matching-portfolio models to detect abnormal changes in credit default swap (CDS) spreads. The sign-test generally dominates the signed-rank test in terms of size, and dominates both the t-test and the signed-rank test in terms of power. Traditional adjustment methods often lead to a misspecified sign-test. We propose a new and parsimonious method (the spread-matched method), which leads to a well-specified and more powerful sign-test. The superiority of the spread-matched method is particularly evident for observations characterized by extreme levels of CDS spread. Analyses of CDS samples differing by contract maturity, data source, and time period confirm these results. We perform an event study on rating downgrades to illustrate how the choice of tests and adjustment methods can affect inference.

5 A review of short-term event studies in operations and supply chain management
بررسی مطالعات رویدادهای کوتاه مدت در عملیات و مدیریت زنجیره تامین-2018
The short-term event study method, grounded in the Efficient Market Hypothesis, is one of the most widely used tools for quantifying the impact of a specific event on a firms shareholder value. As the short-term event study method has been increasingly employed by researchers to investigate various operations and supply chain management (OSCM) events, it is timely to conduct a systematic review of the method to examine how it has been implemented in the OSCM literature and what could be improved to deploy it for future OSCM research. Analyzing 29 short-term event studies published in renowned OSCM journals between 1995 and 2017, we find that OSCM researchers generally follow the standard procedures in conducting event studies, but pay less attention to some methodological issues ranging from addressing the confounding events to expanding the event windows. Based on our analysis, we provide several recommendations for future event studies in OSCM, such as the opportunity for studying external events in the non-U.S. context, the caution of expanding the event windows, and the need to deal with the self-selection bias.
