别拿“甲流”说事儿——大蒜涨价原因探析

2009年大事很多,最震撼人心的非"甲流"莫属,随之而来的是与防控"甲流"相关产品身价倍增,口罩、金银花、板兰根……这些平日不起眼的商品变得炙手可热,而在中国老百姓的生活中,作为餐桌上调味品的大蒜价格可谓一日千里,平日廉价的调味品,一下子成为"贵族菜",价格陡然上涨了几十倍,这与"甲流"的暴发多多少少有些瓜葛,因为据说大蒜具有消毒功能,可以预防甲型流感,难道大蒜价格暴涨都是"甲流"惹的祸吗?其涨价背后的原因值得探究。     

雾霾引爆口罩市场

正随着雾霾的蔓延,口罩无疑是2013年最热销的产品,一天销售数万个口罩对很多网店来说非常轻松雾霾横行,让有"防霾神器"之称的PM2.5口罩在2013年秋冬异常火爆。面对庞大的市场需求,口罩市场却面临品种繁杂、价格混乱、缺乏统一的行业标准等问题。怎一个"乱"字了得目前市面上口罩品种有100多种,价格从0.5     

从口罩到咖啡、从蔬菜到汽车还有什么是中石化不能卖的

这个时代,已经存在的同行不能再被称为竞争对手,未知的才是最可怕的,你永远都不知道对手会是谁。就说卖口罩,从雾霾受到重视的那天起,人们就公认3M。在疫情爆发后,3M口罩脱销,毕竟口罩只是3M诸多业务中的一个小分支。一夜之间,国内很多企业突然开始跨界生产口罩了:五菱、比亚迪等车企去做口罩;全球最大代工厂富士康做口罩;做文胸、内裤、家居用品等纺织类企业开始做口罩;做婴儿纸尿裤的也去做口罩了。

电商平台产品供应链发展探究——基于新冠疫情中“口罩难求”现象的思考

2020年伊始,突如其来的新冠疫情在国内蔓延并迅速引起各界关注。这场没有硝烟的战争不仅是民众个体与病毒的博弈,更是人力、物力、财力的斗争。在国家大力倡导全民戴口罩、而医疗物资相对紧张的情况下,各大电商平台口罩一度断货,出现“口罩难求”现象。文章从电商平台的供应链角度出发,通过对绝大多数平台口罩供应渠道的分析,以及国家政策、市场需求、民众的应激行为对口罩供应的影响,阐述此次疫情中“口罩难求”现象出现的相关因素,并提出对该现象的思考建议。     

全球视角，本土方案

了调查委员会目前正在进行的工作,引起欧洲舆论的震撼。自从去年4月份墨西哥传出甲流报道后,作为流行病学者的沃达格就对有关数字产生了怀疑。当时甲流病毒仅感染了上千人,就有人故意传播,称这是“世纪大流行病”。这种说法的依据是,甲流病毒是一种从未发现过的新品种。但事实上所谓流行疾病的特征就是感染迅速,且每次传染都会出现新的变种、传染给新的载体——动物或人类。

头桥药械:在贡献中获取

江苏省扬州市邗江区头桥镇是全国有名的医疗器械之乡。非典袭来,头桥人感到,这既是一次百年未遇的商机,更是一次产品质量和企业信誉的生死考验。绝不以次充好蒙骗坑害消费者长城医疗器械有限公司,是头桥镇成立最早的私营企业,公司技术雄厚,是全镇唯一一家能够生产活性炭防护口罩的单位。当时社会上形形色色的口罩很多,不乏有一些以次充好的产品,不少人上了当。为了教给消费者识别的技巧,老板耿龙松随手撕开一只有过滤层的活性炭口罩和一只无纺布医用口罩,点上香烟分别吐在两只口罩上,发现一只中间过滤层有黄斑,另一只却没有任何斑迹。他说有…

Confronting indifference toward truth: Dealing with workplace bullshit

Many organizations are drowning in a flood of corporate bullshit, and this is particularly true of organizations in trouble, whose managers tend to make up stuff on the fly and with little regard for future consequences. Bullshitting and lying are not synonymous. While the liar knows the truth and wittingly bends it to suit their purpose, the bullshitter simply does not care about the truth. Managers can actually do something about organizational bullshit, and this Executive Digest provides a sequential framework that enables them to do so. They can comprehend it, they can recognize it for what it is, they can act against it, and they can take steps to prevent it from happening in the future. While it is unlikely that any organization will ever be able to rid itself of bullshit entirely, this article argues that by taking these steps, astute managers can work toward stemming its flood.     

An Anonymous Buyer of Intangible Property

In a market for ideas, an intermediary often masks buyers’ information that is not to be exposed to the public. This article shows that such obscuration plays an important role in removing excess inertia because it prevents the emergence of a bandwagon effect among buyers. This model applies to outsourcing-type R&D competition. Although innovation is spurred, welfare implications are ambiguous because the competition among buyers becomes harsher than it is in the absence of the intermediary.     

Every story tells a picture: Lessons from cartoons on corporate governance

While pictures tell stories, in the case of cartoons, stories also tell pictures. A theory of cartooning suggests that cartoons reflect public sentiment toward issues. As such, cartoons are a useful way of gauging and tracking public sentiment over time. This article uses a historical cartoon analysis to track public sentiment toward issues surrounding corporate governance. Specifically, it compares what cartoons reflected prior to the economic crash of 2008 and what they portrayed after. The criteria of narrative, location, binary struggle, and normative transfer were used as a framework to analyze 258 cartoons. We found that three major changes emerged after the 2008 crash that hold important lessons for those who govern corporations: the public's concern is no longer so much about corporate and individual fraudulent behavior as it is about corporate and individual greed; there is an impression that corporations do not do bad things so much as they do not do any good things; and ordinary people, workers, and taxpayers are those who suffer most when corporations are not governed well.     

Preventing and correcting workplace harassment: Guidelines for employers

In recent years, the number of harassment claims filed with the EEOC has declined overall, but this fact masks a frightening reality: though claims involving some types of harassment have declined, claims for other types of harassment—especially nontraditional forms of harassment—have actually increased. Therefore it remains necessary for employers to maintain a current anti-harassment program, which should consist of the following elements: (1) a clear anti-harassment policy; (2) an explicit statement of prohibited behaviors that can be considered harassment; (3) a complaint procedure that encourages employees to come forward with harassment complaints; (4) protections for complainants and witnesses against retaliation; (5) an investigative strategy that protects privacy interests of both the alleged victim and the accused offender and ensures confidentiality to the extent possible; (6) periodic management training and employee awareness programs that continue to communicate the organization's position on this issue; and (7) measures and processes to ensure prompt corrective action to stop ongoing harassment, and appropriate remedial and disciplinary actions for offenders. In this article, we provide best practice recommendations concerning each of these elements.     

The impact of loneliness on compliance with COVID-19 prevention guidelines

Many individuals have been reluctant to follow the COVID-19 prevention guidelines (e.g., wearing a mask, physical distancing, and vigilant handwashing) set forth by the U.S. Center for Disease Control to reduce the spread of COVID-19. In this research, we use reciprocal altruism theory to investigate the role of loneliness and its impact on compliance with these guidelines. Our findings indicate that lonely individuals are less willing to comply with COVID-19 prevention guidelines than non-lonely individuals. Process evidence suggests that this occurs as loneliness can inhibit an individual's sense of obligation to reciprocate to others. However, we demonstrate that framing information about COVID-19 through agentic (vs. communal) advertising messaging strategies can offset the negative impact of loneliness on compliance with COVID-19 prevention guidelines. Thus, marketers and policymakers may want to consider the important role of loneliness when tailoring messaging appeals that encourage compliance with COVID-19 prevention guidelines.     

Consumer Knowledge and Understanding of Consumer Credit

Much has recently been written about the desirability of restrictive usury laws. While low maximum rates may prevent excessive charges to some, they also limit the ability of high-risk persons to borrow. Therefore, if consumers have a sufficient understanding of the credit market to realize what they are paying for and how much they are paying when they borrow, a case can be made against low maximum finance rates. This article reports on a nationwide study designed to measure consumer knowledge and understanding of consumer credit. The results are that while consumers can generally rank lenders correctly in terms of cost, there are serious gaps in their knowledge of the credit market. Education and income are the key determinants of knowledge and understanding of consumer credit.

DERIVATIVE ASSET PRICING WITH TRANSACTION COSTS1

In the modern theory of finance, the valuation of derivative assets is commonly based on a replication argument. When there are transaction costs, this argument is no longer valid. In this paper, we try to address the general problem of finding the optimal portfolio among those which dominate a given derivative asset at maturity. We derive an interval for its price. the upper bound is the minimum amount one has to invest initially in order to obtain proceeds at least as valuable as the derivative asset. the lower bound is the maximum amount one can borrow initially against the proceeds of the derivative asset. We show that, in some instances, this interval may be strictly bounded above by the price of the replicating strategy. Prima facie, the cost of a dominating strategy should appear to be higher than that of the replicating one. But because trading is costly, it may pay to weigh the benefits of replication against those of potential savings on transaction costs.
