Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation.  相似文献

Abstract

Over the past two decades, there has been a proliferation of research on human resource management (HRM) in Chinese state-owned enterprises (SOEs) as a result of the wide-reaching state-sector reform of the late 1980s. This article aims to provide a systematic review of literature on this topic and capture the nature of HRM in Chinese SOEs, both in research and practice. The article draws on 178 studies from 43 English academic journals over a period of 25?years (1993–2017). In analysing this literature and by taking stock of theoretical frameworks, research methods, themes and analysis of academic articles in this area, we have gained a number of insights. The study has found that the research methods used have shifted from qualitative and interpretive methodology toward quantitative and sophisticated modelling. A further insight is that there has been a relatively heavy reliance on institutional theory in the earlier studies reviewed, and since then a switch towards organizational behaviour perspectives. The level of analysis has moved from macro to micro level and thematic foci have become more diverse and complex. We highlight a number of avenues, theoretical and empirical, for future studies in this field.  相似文献

This paper generalizes Rubinstein and Wolinsky's (1987) model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency, and dynamics. In the benchmark model, equilibrium exists uniquely and involves production and intermediation for some parameters but not others. Sometimes intermediation is essential: the market operates if and only if middlemen are active. If bargaining powers are set correctly equilibrium is efficient; if not there can be too much or too little economic activity. This is novel, compared to the original Rubinstein–Wolinsky model, where equilibrium is always efficient.  相似文献

The design of reverse logistics network has attracted growing attention with the stringent pressures from environmental and social requirements. In general, decisions about reverse logistics network configurations are made on a long-term basis and factors influencing such reverse logistics network design may also vary over time. This paper proposes dynamic location and allocation models to cope with such issues. A two-stage stochastic programming model is further developed by which a deterministic model for multiperiod reverse logistics network design can be extended to account for the uncertainties. A solution approach integrating a recently proposed sampling method with a heuristic algorithm is also proposed in this research. A numerical experiment is presented to demonstrate the significance of the developed stochastic model as well as the efficiency of the proposed solution method.  相似文献

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This study aims to examine the interrelationships among the festival quality dimensions, festival quality, emotion, festival image, festival satisfaction and festival loyalty. Analysis of data from 454 attendees in the 12th Macau Food Festival indicates that the proposed model fits the data. The result of this study will assist festival management in developing and implementing market‐orientated service strategies to increase quality and image, and enhance the emotion and satisfaction of attendees in order to attain their loyalty toward food festivals.

Film‐induced tourism has recently gained increased attention in academic research. Although previous literature has identified the existence of consumer–celebrity attachment, scant empirical studies have examined whether celebrity attachment influences behavioral intentions in a film tourism context. The purpose of this study is to examine the relationship between celebrity attachment and behavioral intentions as well as to clarify the role of place attachment. Survey data from 312 tourists in Taiwan indicate that celebrity attachment is positively related to behavioral intentions. Moreover, place attachment partially mediates the relationship between celebrity attachment and behavioral intentions. Implications of these findings for managing marketing strategies as well as future research directions are subsequently discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.
