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

Successful drug intervention policies rely on timely assessment of size of drug users and close monitoring of trend regarding drug abuse. Taking advantage of data collected by the Central Registration System for Drug Abusers of Macau (CRSDAM), this study applied open population capture-recapture models with data augmentation techniques to estimate the size of drug users and to identify influential factors on capture and survival probabilities from 2009 to 2014. In particular, the data augmentation technique was used to address missing data issues. The estimated size of drug users has been slowly declining from 2442 (95% Bayesian credible interval [BCI] 2042–2914) in 2009 to 807 (95% BCI 654–1000) in 2014 with a small fluctuation of 2251 (95% BIC 1950–2599) in 2011, and the estimated cumulative size of drug users is 6199 (95% BCI 5651–6873), which is correspondent to a prevalence rate of 1.20% of the current population aged 15 to 54. Although the estimated sizes of total, narcotic, and other drug users were declining, the size of stimulant users might be increasing. People who used narcotics as their first drug and who were reported by governmental agencies were more likely to stay in the registration system, while those who used needle injection were less likely to stay. Governmental agencies, higher education, and using needle injection were negatively associated with the probability of capture over time, while using narcotics as the first drug was positively associated with it.  相似文献
