公务卡结算方式的探讨

实行公务卡结算方式,可以监督公务消费,强化财务管理,降低管理成本,提高工作效率,实现政府与银行的和谐发展。但公务卡结算方式存在着弊端,公务卡受理环境有待进一步改善,公务卡使用缺乏有效执行力、监督力。应改善消费环境,改变浪费观念,加强财政预算资金的管理和监控,促进现代财政国库管理制度建设,提高政府部门的财务管理效率,从机制上防范和治理腐败,实现公务消费的公开、真实、透明。     

Implementations of the Nash solution based on its Walrasian characterization

Summary. The present paper provides three different support results for the Nash bargaining solution of -person bargaining games. First, for any bargaining game there is defined a non-cooperative game in strategic form, whose unique Nash equilibrium induces a payoff vector that coincides with the Nash solution of the bargaining game. Next this game is modified in such a way that the unique Nash equilibrium that supports the Nash solution is even in dominant strategies. After that an -stage game in extensive form is presented whose unique subgame perfect equilibrium supports the Nash solution of the bargaining game. Finally, the support results are shown to induce implementation results in the sense of mechanism theory. Received: October 3, 1999; revised version: October 26, 1999

Office-based and home-care for older adults in primary care: A comparative analysis using the Nash bargaining solution

Three care delivery settings are compared in this study: office-based care, home-care, and mixed-care, i.e., office-based care combined with home-care, in solo, small, medium, and large primary care practices. The objective of this paper is to identify which of these settings better achieves the secondary goals of the so-called quadruple aim, i.e., reducing costs, improving the patient experience, and improving the physician experience. A multi-objective integer programming formulation is developed to capture the elements of strategic health care planning. The formulation considers the minimization of four objective functions: the total cost of care workers, the total number of care workers, the total rejected demand and unsatisfied preferred care location, and the total panel size of the providers. Instead of computing the entire Pareto frontier, we used the Nash bargaining solution to determine a single Pareto optimal solution for the problem. The approach was tested using real world instances, which can be adjusted to any specific primary care practice. The numerical results show that none of the settings provides the smallest values in all objective functions. The choice of a setting for a primary care practice depends on the secondary goals that the practice desires to emphasize, and, in most cases, it is independent of the type of practice size. For the analyzed instances, a calculated overall score for each setting determined that, on average, the settings based on home-care strengthen the achievement of the secondary goals of the quadruple aim more so than in comparison to the office-based physician settings.     

What drives bilateral foreign direct investment among Asian economies?

This study analyses the role of knowledge transfers via bilateral foreign direct investment (FDI) among 31 Asian economies. We make three distinct contributions to the literature on the drivers of FDI by: (1) applying the knowledge-capital model to FDI among Asian economies for the first time, using a comprehensive data set, and comparing it to an empirical gravity-type model of FDI; (2) conducting model selection tests to choose between alternative empirical specifications and estimation methods; and (3) modelling both the FDI participation decision and the decision on the amount of FDI. The main findings are: (1) while vertical FDI, driven by seeking low-cost unskilled labour, appears to be the dominant type of intra-Asian FDI, overall the knowledge-capital model is not supported by the data; and (2) conventional gravity variables (e.g., size, distance, common language) provide a better explanation of intra-Asian FDI and, therefore, a more suitable vehicle for future research.
