We analyse the legitimacy of public enterprises that perform economic activities by focusing on the citizens’ subjective preferences, i.e. determining their political legitimacy. Using data from a representative survey conducted among 318 citizens of the German state of Rhineland‐Palatine, we explore determinants for the support of either privatisation efforts or the instrumental thesis, a widespread principle in German‐speaking countries, which considers public enterprises solely as instruments to fulfil economic policy objectives. Our results indicate that the respondents’ perception of the efficiency of public enterprises as well as their personal economic situation are important factors for the support of privatisation. The influential factors for the use of public enterprises as policy instruments are political ideology, the perception of a higher security of supplying goods and services as well as opinions regarding corporate social responsibility. The subjective preferences of a (democratic) country's citizens are thus an important reason why the public sector should or should not play an active part in providing goods and services. This can play an important role when decision makers from the public sector are keen to take into account the citizens’ approval or disapproval of privatisation measures.  相似文献

Strategy researchers now recognize that distinctive competencies are critically important for sustained competitive advantage. The processes by which such competencies are acquired, however, has only started to be examined. Connections between macro-industrial system level properties and micro-developments in proprietary technology at the firm level need to be made. This paper argues that system-wide properties, such as long-standing elementary and opposing logics in societal forces like governments and markets, and micro-developments, such as the firm's capacity to search for talent, technology, and ideas and to harmonize what it learns internally, can contribute in significant ways to the creation and acquisition of new competencies. Based on the case of pollution prevention in electric generation, it shows how the system-wide properties channel and direct the paths that the acquisition of new competencies take and how they interact with micro-developments at the firm level. © 1998 John Wiley & Sons, Ltd.  相似文献

Despite the argument that leveraging the expertise of foreign subsidiaries to the global firm benefits the whole firm's competitive advantage, in the case of international innovation, such leveraging rarely takes place. We investigate this paradox, applying research on strategic initiatives to the context of international R&D. Developing a conceptual model on the basis of communication psychology, we analyse how the innovative expertise of R&D subsidiaries may be leveraged to benefit the global firm. Specifically, we determine six elements whose greater exploration can lead to a deeper understanding of how the innovation expertise of a foreign R&D subsidiary may be leveraged.  相似文献

Landlords offering a house in the rental market face a difficult strategic pricing decision. The revenue maximizing decision for the landlord involves a tradeoff between the rental rate and time on the market. Because the turnover of renters is higher than owners, and because the landlord must bear some carrying costs on a vacant house, pricing the rent too high may decrease revenue due to a higher vacancy period and pricing it too low may reduce the revenue when occupied. While there is substantial research on the relationship between listed prices and time on the market for freehold interests, this is the first study to provide empirical evidence on the relationship between asking rent, contract rent and time on the market for single family residential rental (leasehold) property interests. We present two models; a rental price model and a duration model for time-on-the market. Using data from the Dallas–Fort Worth area we find that landlords who set a lower asking rent relative to predicted rent can expect a shorter marketing period for their properties. The results also indicate that overpricing the asking rent and then lowering it at a later date leads to a longer marketing time (after the reset) and often a lower rent. These finding are reasonably robust for low-, mid-, and higher-valued rental properties.

Foreign firms trying to protect their intellectual property rights (IPRs) in emerging economies are suffering real pressures because these economies usually offer little or no enforcement of IPR. Foreign firms therefore have to resort to approaches unlike those they use in developed countries. This paper explores what managers of foreign firms in China have already tried in their efforts to achieve effective IPR protection – specifically, they have crafted de facto strategies that can protect IPR without using China's legal system or engaging in lawsuits against imitators. These strategies work, and this paper explains how and why, thus offering a potential template for IPR protection in other economies with weak appropriability systems.  相似文献

本文首先基于可持续生计框架,引入劳动力迁移的视角,之后改进农户模型以分析劳动力外出务工对流出地家庭生计策略的影响机理,并利用陕西秦岭北麓地区1074户的调查数据进行验证。结果发现:外地打工虽然有利于家庭的资本积累,但会阻碍流出地非农生计活动的参与和劳动力供给;本地打工在促进资本积累的同时,对参与林(经济)作物种植、养殖和自营等生计活动有显著的促进作用,但过多的劳动力外出务工仍然会减少本地其它活动的收入水平。  相似文献

Acquisition of innovative firms is a widely observed phenomenon in high-tech industries. On the basis of distinct advantages of large and small firms, in this paper, we build a tournament model with possible acquisition activity of large firms to derive hypotheses on interdependencies between acquisition frequency and post-acquisition success rates. We find empirical support for our hypotheses that (1) acquisitions increase overall innovation output and (2) that the number of acquisitions is higher in industries with larger heterogeneity between established firms and young start-ups. However, our third hypothesis derived from the formal model that innovation success following from acquisitions varies across industries is only partially confirmed.  相似文献

The risks from consuming self‐caught fish are receiving international attention because of high levels of contaminants in some species. The ethnic, income, and educational differences in fishing and fish consumption patterns of 202 anglers fishing along the Clinch River arm of Watts Bar Reservoir adjacent to the US Department of Energy's Oak Ridge Reservation (ORR) or along Poplar Creek within ORR boundaries were analyzed to understand how to design a risk communication strategy. Because of elevated PCB concentrations in striped bass (Morone saxatilis), catfish (Ictalurus spp.), and sauger (Stizostedion canadense) due partly from contaminants released from the ORR in East Tennessee, the Clinch River arm of Watts Bar Reservoir is under a fish consumption advisory, while portions of Poplar Creek are under advisories because of mercury. Most studies find that a high proportion of anglers eat their catch, and people with lower incomes and less education generally eat more self‐caught fish than others fishing in the same region. Calculating fish consumption individually for each person indicated that a considerable number of people ate more fish from the study area than the amount used to calculate risks when developing fish consumption advisories, and people who ate fish more often usually ate larger portions. Unlike previous studies of fish consumption, this study indicated that a smaller proportion of anglers ate their fish, and those that ate the most were the high income anglers for this fishing population, rather than those with lower incomes. This suggests that risk communication strategies must include site‐specific information on the population at risk from fish consumption, and that targeting only low income, low education anglers will miss some people who are most at risk.  相似文献
