Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.  相似文献

This paper reports on a field study of how a range of inter-institutional and inter-organisational forces shape the evolving rhetoric and practice of multiple accountabilities in public services. Drawing on the institutional logics perspective, we carried out a qualitative field study in the Australian Commonwealth Public Service involving semi-structured interviews, two focus group discussions, and the examination of internal accounting, management reports, and government archival records. The findings suggest that emphasis on conventional instrumental mechanisms and reporting tools, such as budgeting and accrual-based reporting, support managerial (instrumental) accountability through compliance logics. We conclude that an emphasis on public (relational) accountability through public dialogue is central to the public sector accountability debate, and that more attention needs to be paid to the question of how to balance the dual logics (instrumental and relational) in public services. The findings provide practical insights for public sector managers, policymakers and governments responsible for designing and implementing reforms, accounting tools, and accountability practices.  相似文献

Last year, 2020, was the 50th anniversary of the opening of the ‘Chilean road to socialism’ by Salvador Allende. Although the Allende government is the political reference for the 'socialism of the 21st century’ in Latin America, international supporters tend to disregard the primary cause of its downfall, focusing instead on the circumstances of Allende's death. This article explains the link between the Allende government's development policies and its macroeconomic outcomes between 1970 and 1973. It finds that Chile's economic collapse had an endogenous cause related to government policies. This supports the views of Mises and Hayek on the feasibility of socialist economic policies. Policymakers and commentators should recognise essential lessons from the Chilean experience to learn from past errors and effectively promote Latin America's economic development.  相似文献

当前,合作社异化已成为阻碍合作社进一步发展的痛点,其中"合作制"下社员剩余索取权和控制权的丧失是矛盾核心,因而探求其改进方式对合作社长远发展、实现乡村振兴有重要意义。本文基于效率与公平衡量维度,通过对MGL合作社这一典型案例进行剖析发现,有效的合作社在治理结构和利益分配上具备"合伙人制"特征,并且基本契合不完全契约理论有关能够有效解决契约双方信息不对称以及剩余索取权、控制权被少数社员占有的论述。对此,应充分重视合伙人制在合作社发展中的内在有效性,弱化其是否具有规范的外在形式。  相似文献

Social scientists have developed several theories for understanding or evaluating policy change over time. Since all costs or benefits are not internalized owing to positive transaction costs, policymaking is always implemented under cost underestimation conditions and, therefore, is imperfect. I call this trait policy failure in this article. Furthermore, I show that a new framework combining the social costs approach and the legal/economic approach in institutional economics is suitable and can be applied to evaluating how past policy failures affect present policy, providing as an example the Fukushima nuclear disaster in Japan.  相似文献

Genetically modified organisms (GMOs) have been a controversial issue in the European Union (EU). A growing number of member states and regions within the member states oppose the EU’s agro-biotechnology policy, resulting in a complex multi-level structure of policy-making. This study is interested in the regional opposition to GMOs and scrutinises the determinants of membership in the European Network of GMO-free Regions. In terms of theory, this study builds on the literature of policy diffusion. For the analytical purpose, we distinguish among four diffusion mechanisms: learning from earlier adopters, economic competition among proximate regions, imitation of economically powerful regions and deviation from national law. Our research questions are the following: How has membership developed since the foundation of the network? Which mechanisms explain the diffusion patterns observed? The empirical findings show that membership in the network has grown substantially between 2003 and 2014, which supports the general expectation that there is a diffusion of GMO-free regions. Yet, most new member regions are located in the same member states as the regions that founded the network. In other words, what is observed is intra-country diffusion rather than inter-country diffusion. The empirical findings provide support for the importance of learning from earlier adopters for the growing of the European Network of GMO-free Regions.  相似文献

Research and practice have observed a shift towards service-oriented approaches that depend on input from citizens as co-producers of services. Yet in the delivery of public infrastructure the focus is still on managing assets rather than services. Using a Policy Delphi approach, we found that although experts advocate service-centric approaches guidelines and policies lack a service-centric perspective. Findings revealed a range of impediments to effective stakeholder involvement. The paper contributes to co-production and new public governance literature and offers directions for public infrastructure decision-makers to support and reconnect disengaged government–citizen relations, and determine ways of understanding optimal service outcomes.  相似文献

Airport capacity constraints are increasingly challenging the growth of air traffic. At the same time, decision-making about airport capacity investments is extremely complex, involving trade-offs. This paper’s objective is to optimise a privately owned airport system’s capacity investment decision in a city under demand uncertainty. Next to the investment size, our real options model incorporates the timing of the investment, as well as the cost of congestion. The results reveal that the larger a city’s initial airport capacity, the smaller its investment will relatively be and the lower the occupancy rate threshold at which investment will take place. We also show that, in case of a higher demand growth combined with more demand uncertainty, the city will benefit from a significantly larger investment, but made later at a higher occupancy rate. In this case, cities with a small initial capacity will sometimes even more than double current capacity. Higher airport charges and an increase in non-aeronautical revenues both lead to a later investment in more capacity, due to the increased project attractiveness. An increase in congestion costs results in a larger investment made earlier, in order to eliminate delays. Airport operational cost and capacity holding cost increases both lead to smaller investments.  相似文献

This research focuses on understanding the air taxi operations to determine the number of air taxis required to fulfill the demand for urban air mobility in New York City (NYC). We leverage the Define, Measure, Analyze, Design, and Verify (DMADV) framework and integrate it with the systems simulation approach. Upon investigation, we find that all the parameters linearly impact the vehicle utilization, while other measures are robust, specifically with respect to the seating capacity. It is also recommended to operate initially with 70 air taxis in NYC to achieve a trade-off between customer wait time and vehicle utilization. The proposed approach can act as a recommender system for air taxi companies.  相似文献
