A general theory of cross-subsidization due to inframarginal support is developed. Two sources of output distortion are identified: exit deterrence and extramarginal output. Some firms would not be in business without the subsidy. Cost savings due to declining average costs are always greater than the losses incurred where price equals marginal cost. Moreover, it is theoretically possible for inframarginal subsidies to expand output more than equivalent fully coupled subsidies. Empirical analysis of U.S. dairy subsidies isolates these components of cross-subsidization and finds distortions from inframarginal support to be substantial, with implications for trade negotiations, dispute settlement, and policy formulation.  相似文献

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.  相似文献

This article explores consumer investment choice in long-term energy conservation technology and assesses trade-offs in energy saving behaviour between the housing and transportation domains. The long-term energy conservation choice problem is conceptualized as a portfolio choice problem. Consequently, to measure trade-offs between investments in housing and transport options, a cross effects choice design is developed in which respondents were shown one or more alternate ways to reduce their current energy consumption: (1) investing in new technology in the house, such as solar panels; (2) exchanging the current car for a more energy efficient car; (3) buying a new energy-efficient car, such as EV or solar car; (4) moving house to reduce current travel distances. To help respondents linking these options to their current energy consumption, a new Web-based survey system (SINA) to implement and administer stated adaptation experiments was developed. The system was used to collect two sets of data. First, data about out-of-home and in-home energy consumption, together with detailed time use data, was collected. Second, using a cross effects design, respondents were asked to select a portfolio of energy-saving strategies in response to different energy pricing policy scenarios. Results reported in this paper are based on 572 respondents who completed the survey and responded to seven adaptation questions based on their current energy expenditures. A random parameters logit model is estimated to predict the probability of choosing a particular portfolio of energy-saving options. Estimation results indicate that individuals from different socio-demographic groups exhibit varied preferences. The saving option characteristics, especially cost related characteristics have significant effects on individuals' preferences. Moreover, the results also showed significant effects of choice set composition on energy saving options. Further, the energy pricing policies had showed mixed effects on individual's preferences.  相似文献

Research summary : In family businesses, investment decisions often involve both socioemotional wealth and economic considerations. Focusing on new technology adoption, we argue that multiple dimensions of socioemotional wealth contribute to complex effects within different types of family firms—depending on the level of family control—as well as in contrast to non‐family firms. Results based on cable TV operators from 1983 to 1987 confirm that family ownership correlates negatively with technology adoption, especially when family owners hold a minority rather than majority position. We also show contingencies based on performance improvements and competitive threats. Our arguments contribute new insights about the tensions between economic and socioemotional factors within minority family ownership that are absent from non‐family firms and more pronounced than in majority family firms. Managerial summary : We find evidence of greater reluctance toward new technology adoption among firms with minority family influence than majority family influence. This suggests that goals related to socioemotional wealth only partly explain the cautious decision‐making observed in family firms, with further caution arising from conflicting priorities between family and non‐family owners. Recent performance improvements help offset the reluctance to adopt new technology, albeit to a lesser degree among firms with minority family ownership. High levels of competitive threats also offset the reduction in new technology adoption, and contrary to expectations, to a greater extent among minority family firms.

Entrepreneurship is commonly held to be a vital force in the US and other economies. Yet, little is known regarding the efficacy of entrepreneurial efforts developed in one country but attempted elsewhere. In response to calls for testable theoretical models, scholars have begun to investigate empirically the attendant phenomena associated with the venture development process. This article describes efforts to test in another nation a nine-stage entrepreneurial process model of venture development derived and validated in the USA. While some development stages appear to exist similarly across borders, others may not be present. Further, the sequence of stages in the US-derived model may differ when compared internationally.  相似文献

Individuals make decisions about whether innovations are adopted and transferred to new uses or locations. This Paper argues that relational competence Is critical for innovation management and technology transfer and that personal communication, formal and informal, is the core component in such competence. It shows how “close ties” and communication are critical to innovation, particularly given the changing nature and role of technolop management in the context o f rapidly increasing globalization. This is illustrated with reference to the communication in he mindset and practice of technology partnering in Australia's participation in the aerospace and telecommunications industries.  相似文献
