Focusing on foreign ownership in the private firm, we examine the Cournot-Bertrand comparison in a mixed oligopolistic market with vertical market structure. We have found that if public and private firms were charged with uniform price for their inputs, then Cournot-Bertrand ranking in market outcomes confirms those obtained by Ghosh and Mitra (2010). This implies that under uniform pricing in the upstream sector, the vertical market structure does not have substantial influences on Cournot-Bertrand ranking. However, if discriminatory pricing is adopted, firm's profits, output, and social welfare are often reversed to those obtained from uniform pricing in the upstream sector. Given the closeness of products, if the share of foreign ownership is sufficiently low, social welfare in Cournot competition can exceed that of Bertrand competition, contrasting with the standard welfare ranking that Bertrand welfare is strictly higher than Cournot. This implies that Cournot competition can be more socially desirable than Bertrand in mixed oligopoly with vertical market structure if discriminatory pricing scheme is adopted by foreign upstream monopolists. 相似文献

We revisit the relationship between the optimal privatization policy and market competition indexes such as the Hirschman–Herfindahl index. It is affected by the number of the firms and asymmetry among the sizes of the firms; the smaller the number of firms and the more asymmetry among firms, the higher the market concentration index. The literature on mixed oligopolies suggested that the optimal degree of privatization increases with the number of private firms, and thus, decreases with the market competition index, assuming that all private firms are homogeneous. We investigate how asymmetry among private firms affects the optimal degree of privatization. We propose the simplest and natural model formulation to discuss asymmetry among private firms. We find that the optimal degree of privatization is either nonmonotone or monotonically increasing, and thus never monotonically decreasing, in asymmetry among private firms. 相似文献

Death is inevitable; yet, not all consumers prepare for death by purchasing end‐of‐life (EOL) products. Using the theory of reasoned action (TRA) and the dual‐process model framework, this study aims to examine the role of emotions and cognitions in influencing consumers' decisions to engage in planning for death. A mixed methodology design was used. Study 1, a qualitative study, uncovered positive and negative emotions and deliberative reasoning that comprise consumers' EOL purchase decision process. Study 2, a quantitative study, confirmed that emotions and deliberations independently and jointly influenced consumers' EOL attitude and behavior and that emotions affected deliberations for both prepaid funerals and wills. Subjective norms outperformed attitude in predicting both products' purchase behavior. These finding supported the dual‐process model of behavior and the TRA in the EOL research context and contributed to the EOL literature by investigating the effects of emotions and deliberations concurrently; thus validating the important role of emotions in influencing EOL planning and purchase. In light of our findings, marketers could, after due cognizance of the morbidity and sensitivity of the topic, develop actionable promotional and segmentation strategies for EOL products and other emotion‐laden, unsought products and service. 相似文献

In this research note, I revisit the issues raised by Jerry Petr (1987) in “The Nature and Necessity of the Mixed Economy.” The institutionalist mixed economy is still a sound model for the good society. However, Western industrialized countries have been losing ground on the goals of the mixed economy. The struggle to defend pragmatism over ideological attachment to neoliberalism, has evolved into a distributional struggle that cannot be resolved without institutional change. 相似文献

We investigated how people's recreational activities, values, and land use preferences are related to the protection level, biodiversity and cultural heritage values of nature-based tourism areas in northern Finland. We assessed peoples' opinions using a public participation geographic information system (PPGIS) and analyzed the data together with spatial biodiversity and cultural heritage data from the same area. Associations between the PPGIS place markings with the protection level and biodiversity values were quite low, and for the cultural heritage sites they were altogether missing. Negative preferences were often marked in areas with high numbers of sites rated as pleasant and they overlapped with each other, indicating conflicting preferences. Since most activities are not noticeably related to the protection level or biodiversity values of a site they can be planned so as to protect the biodiversity of the area. 相似文献

互联网金融作为互联网技术与传统金融融合后的新兴业态模式,具有降低交易双方成本,提升金融服务效率和便捷性的作用,在满足了个性化金融服务需求的同时,还促进了我国普惠金融发展。但随着互联网金融模式的不断丰富,互联网金融混业经营及脱媒现象加剧,在缺乏监管和法律定位不明的情况下,互联网金融给消费者带来诸多潜在风险。对此,需要按照时间发展顺序,在短期内强化互联网金融消费者权益保护相关政策措施,保证互联网金融市场平稳发展;中长期则注重互联网金融发展质量,通过不断完善互联网金融消费者权益保护机制,进而构建具有综合性特征的互联网金融消费者权益保护体系。 相似文献

作为国有企业产权改革主要模式,“混合所有制”改革是否有助于确保国有资产保值增值,是否有助于推动中国经济可持续发展等问题仍存在探讨空间。本文基于对于改革开放以来中国国有企业改革的成就和教训的考察,指出“混合所有制”可以作为竞争性部门国有企业改革的一个过渡形式;对于垄断央企的改革应该充分借鉴国际上自然垄断行业的改革经验,打破行政垄断,推动竞争性框架建立,并切实实现从“管企业”逐步调整为“管资本”,通过改革实现国有资产的保值增值,并为经济创造新的增长点。 相似文献

In a bid to reduce greenhouse gas emissions, several countries worldwide are implementing policies to promote electric vehicles (EVs). However, contrary to expectations, the diffusion speed of EVs has been rather slow in South Korea. This study analyzes consumer preferences for the technological and environmental attributes of EVs and derives policy and environmental implications to promote market diffusion of EVs in South Korea. We conduct a choice‐based conjoint survey of 1,008 consumers in South Korea and estimate the consumer utility function using a mixed logit model considering consumer heterogeneity. Based on the consumer utility function, we analyze consumers' willingness‐to‐pay (WTP) for EV attributes such as driving range, charging method, charging time, autonomous driving function, carbon dioxide (CO2) reduction rate, and purchase price. The results indicate that the current low acceptance of EVs is due to their relatively high price and lack of a battery charging technology that satisfies consumers' expectations of the charging method and time. One interesting finding is that Korean consumers have a relatively higher WTP for the CO2 reduction rate of EVs than consumers in other countries; however, they do not consider CO2 reduction over other technological attributes when choosing EVs. This implies that the rate of CO2 reduction of EVs is not an important factor for South Korean consumers when buying EVs. We also calculate the effect of CO2 reduction with the market penetration of EVs and find that CO2 reduction through the diffusion of EVs depends on the country's electricity generation mix. 相似文献

将人力资本在所有制企业间的配置扭曲(错配)理解为技术配置扭曲和规模配置扭曲两个方面,基于1998—2013年中国工业企业数据库的相关数据,探讨国有企业混合所有制改革影响人力资本配置扭曲的内生机理,结果表明:混合所有制改革鼓励非国有资本通过参股、控股和并购等方式参与到国有企业的生产决策中,这有助于完善国有企业的公司治理结构和利润分配机制,进一步缓解人力资本的技术配置扭曲和规模配置扭曲程度;相对于非行政垄断行业,行政垄断行业中国有企业混合所有制改革对于人力资本配置扭曲的缓解作用较小。 相似文献
