This paper models the effect of firm-level profitability (earnings before interest and taxes and return on sales) against certification by former members of the U.S. Congress. Although some scholars have studied certification, none have studied certification in the public policy market as is done in the current work. Likewise, although scholars have studied the effects of lobbying and political connections on firms' outcomes, none have studied lobbying through former Congress members specifically. The findings confirm that, after controlling for numerous factors, firms can use former Congress members to effectively lobby and certify their intentions. Both firm-level earnings before interest and taxes and return on sales were significantly associated with prior lobbying efforts by these former elected federal officials in several different estimation techniques employed in the study.  相似文献

Two separate frameworks have existed for the analysis of social predicaments in which businesses play a role: issues management and stakeholder management. In this paper, we argue that the chasm dividing these two literatures is artificial, and potentially obstructive to the advancement of our knowledge of the position of business in contemporary societies. The position we take in the present paper is that all social predicaments have an issues side as well as a stakeholder side and that a dual focus on both issues and stakeholders is therefore essential to understanding the evolution of these predicaments and crucial to managerial dealings with these issues. We present an integrative co-evolutionary framework, explaining the dynamics between issues and stakeholders in all consecutive stages of a predicament's evolution. The framework proposes a new way of thinking about issues and stakeholders, as such facilitates a deeper understanding of how the social environment of business is constituted, and offers new insights for the practical management of issues and stakeholders.  相似文献

Between 1968 and 1974 Italy was subjected to an unusually virulent campaign of right‐wing terrorism and subversion. An illustrative episode associated with this so‐called ‘strategy of tension’, which was characterized by the systematic use of covert ‘false flag’ operations, was the 17 May 1973 grenade attack outside Milan police headquarters that resulted in four dead and over 40 injured. Although the perpetrator, Gianfranco Bertoli, claimed to be an ‘individualist anarchist’ and had in fact established contacts with certain anarchist and leftist groups, subsequent judicial investigations revealed that he had been an informant and infiltrator for the Italian military intelligence service, that he had long maintained links with various anti‐communist and neo‐fascist organizations, and that he apparently received ‘cover’ and some type of logistical support prior to the attack from one or more ‘international secret services’. Although many aspects of the crime still remain murky, in all probability Bertoli was an agent provocateur acting on behalf of clandestine, quasi‐official intelligence apparatuses rather than a solitary anarchist engaging in violent ‘propaganda of the deed’.  相似文献

Although all good social science research is by its very nature comparative, criminology and criminal justice have only recently embraced cross‐national research as a mainstream activity. This paper presents a brief history of the development of the subfield of empirical comparative criminology and criminal justice, assesses a typology of comparative studies, and identifies sources of comparative data. In addition, the paper discusses the benefits and drawbacks of using various available data sources which support macro‐, micro‐, or mixed‐ level analyses. Finally, the paper discusses the impediments to and the future of comparative crime and criminal justice research.  相似文献
