基于期权博弈的PPP项目特许权期决策模型

运用期权博弈方法,从无政府担保基本情形出发,构建 PPP 项目特许权期决策模型,考量政府参与风险分担对特许权期的影响。结果表明,收益波动率一定的情况下,特许权期随着政府最低收益担保期望价值的增加而减少;而在政府最低收益担保期望价值一定的情况下,特许权期随着收益波动率的增加而增加。鉴此,政府应根据项目的风险收益情况实施弹性特许权期制。     

碳交易与碳税机制比较研究

碳税和碳交易作为主要的碳减排政策工具被大多数重视碳减排的国家所采用。基于对比碳税与碳交易在理论基础、效果成本、减排效果、监督机制以及未来适应性等方面的差异,结合两种政策的执行现状和中国国情,中国应建立碳排放交易与适度碳税相结合的复合政策,降低碳排量,以应对日益凸显的环境问题。

Unlikely Pivotal States in Competitive Free Trade Agreement Diffusion: The Effect of Japan's Trans-Pacific Partnership Participation on Asia-Pacific Regional Integration

How can a state with dysfunctional trade politics spur the negotiation of major free trade agreements (FTAs)? Using the case of Japan's participation in the trans-Pacific Partnership (TPP), we develop an analytical framework on FTA diffusion that takes into account multidimensional (economic, legal and political) competitive pressures, and the ability of states to act as pivots in triggering FTA cascades. We disaggregate the makeup of a pivotal state into two main components – capability and credibility – and underscore Japan's significant latent capabilities, but also its serious credibility shortcomings. The TPP's boost to Japan's credibility raised the possibility of significant economic, legal and political externalities for specific countries which responded by accelerating FTA initiatives that had long stalled: the trilateral China–Japan–Korea FTA, a 16-state East Asian FTA and the Japan–European Union trade negotiations. This study extends the theoretical frontier in policy diffusion studies by clarifying the combination of factors that allows some states, but not others, to activate the externalities behind the dissemination of defensive FTAs.

Small system dynamics model for alleviating the general practitioners rural care gap in Ontario,Canada

The disproportionate concentration of healthcare professionals in urban areas is a concern in many countries, including Canada. A need to address this rural care gap has driven a large number of government led initiatives worldwide over the years. This paper presents a model that can be used as a tool to examine the efficacy of such policies on the workforce distribution in the long term. A small system dynamics model is employed to simulate the current and future distribution of general physicians at a jurisdictional level. The model represents the transition of general practitioners to provide insight into the dynamics of care provision over time. The movement, and competition, between rural and urban areas is modeled to enable detailed exploration of the ability for proposed measures to alleviate the care gap in the future. Among the tested policies are such commonly used initiatives as financial incentives to rural professionals, promotion of medical education in rural areas, expansion of rural education programs and the engagement of international medical graduates etc. We demonstrate how the model can be used as a tool to determine an efficient and well-chosen combination of policies which can help alleviate the rural care gap in the future, given that some policies are more effective than others alone but also combined with other initiatives. The presented small system dynamics model is tested on Canada's reality, but its simple nature lends itself to easy application to other countries that experience a similar problem.     

Effects of control on the performance of information systems projects: The moderating role of complexity risk

Control of projects is a core issue for organizations. Successful projects, such as information systems projects, enable organizations to develop a superior supply network and enhance the capability of operations management. A few studies have investigated the effects of control on project performance; however, complexity risk has not been integrated into the relationship between control and performance. Limited evidence has been provided concerning whether modes of control differ in their effectiveness in the presence of a single risk factor. Based on quantitative data obtained from 128 information systems projects, behavior, outcome, clan, and self-control are empirically determined to be positively associated with the system performance of projects. However, complexity risk generates a mixed moderating effect on the relationship between control and performance. In the presence of a high complexity risk, the effects of behavior and self-control on performance are low, whereas the effectiveness of outcome and clan control increases. This finding implies that complexity risk is a double-edged sword with regard to control. Each control mode exhibits different characteristics and effectiveness under high complexity risk. Therefore, appropriate control modes should be carefully selected, and highly effective control modes, such as outcome and clan control, should be prioritized in managing complex system projects.     

Cost-sharing in directed networks: Experimental study of equilibrium choice and system dynamics

This study reports the results of an experiment on directed networks with positive externalities induced by cost-sharing. Subjects participated in a network game in which they had to choose between private and public transportations. If a player chose public transportation, then she shared the travel cost equally with other players making the same choice, whereas if she chose private transportation, then her travel cost was fixed. Travel costs on the private route were manipulated across the two experimental conditions. In one condition, these costs were homogeneous among players; in the other condition, they were heterogeneous among players and only privately known. We found that half (none) of the player groups in the homogeneous (heterogeneous) condition converged toward the efficient equilibrium. Examination of the system dynamics shows that convergence toward efficiency was facilitated by: (1) the existence of an intermediate equilibrium choice; and (2) strategic teaching by which a farsighted player chooses strategies with poor short-term payoff in order to shift group decisions to the efficient equilibrium and thereby increase her own long-term benefit.
