Finite lifetimes,long-term debt and the fiscal limit

The U.S. faces exponentially rising entitlement obligations. I introduce a fiscal limit—a point where higher taxes are no longer a feasible financing mechanism—into a Perpetual Youth model to examine how intergenerational redistributions of wealth, the average duration of government debt, and entitlement reform impact the consequences of explosive government transfers. Three key findings emerge: (1) Growing government transfers cause more severe and more persistent stagflation than in representative agent models that do not capture intergenerational transfers of wealth; (2) A longer average duration of government debt pushes the financing of government liabilities into the future and reduces the short-run impacts of explosive transfers; (3) The time it takes the economy to rebound from a period of growing transfers increases exponentially with the number of years it takes to pass entitlement reform.     

政府投资项目造价管理改革思路及建议

政府投资项目主要投资在与国计民生密切相关的产业,使用的是公共资金,公众都应有知情权,管理过程受到社会的广泛关注。虽然我国政府投资项目造价管理改革突破了传统体制束缚,己取得初步成效,但是现行管理方式也确实存在许多值得探讨和完善的地方。本文结合国内政府投资项目造价管理现状,提出改革的具体措施及建议,期望为政府投资项目造价管理提供理论和实践的指导。     

论企业中职务消费纳入薪酬体系的合理性

职务消费过度、过滥问题十分严重。现行职务消费制度的不合理引发了一系列社会和经济问题,改革刻不容缓。将职务消费纳入企业薪酬体系是根本的改革途径,职务消费和薪酬体系其他部分本质上的一致性使它们能够组成一个和谐的整体。改革的基本思路是缘于“总额限定、节余归己”的激励性质的制度安排。可以从五个方面入手进行全面的改革尝试,即:对职务消费项目进行归类管理、严格预算和总额限定制度、授权管理、完善监督约束机制、建立健康的企业文化。

Coloured Logic Petri Nets and analysis of their reachable trees

Logic Petri nets (LPNs) can describe and analyse the batch processing function and passing value indeterminacy in cooperative systems, and alleviate the state space explosion problem. However, the indeterminate data of logical output transitions cannot be described explicitly in LPNs. Therefore, Coloured Logic Petri nets (CLPNs) are defined in this paper. It can determine the indeterminate data of logic output transitions in LPNs, i.e., the indeterminate data can be represented definitely in CLPNs. A vector matching method is proposed to judge the enabling transitions and analyse CLPNs. From the marking equation and the proposed reachable tree generation algorithm of CLPNs, a reachable tree can be built, and reachable markings are calculated. The advantage of CLPNs can be shown based on the number of leaf nodes of the reachability tree, and CLPNs can solve the indeterminate data of logical output transitions. Finally, an example shows that CLPNs can further reduce the dimensionality of reachable markings.     

Competition or Oligarchy?: The Jordanian Business Elite in Historical Perspective

Abstract

It is of ten stated that eco nomic re form in Jor dan is com -pli cated by the fact that the rent cir cu la tion dur ing the oil boom of the 1970s and early 1980s has led to the emer gence of an allocative state sub or di nat ing the pri vate sec tor. How ever, as I will ar gue in this pa per, there ex ists a pri vate sec tor elite in Jor dan en joy ing vast priv i leges that con trib utes to the prob lem of trans form ing a rent-based econ omy into a fully-fledged, com pet i tive mar ket econ omy.

The Asian crisis and the implications for human resource management in Vietnam

Vietnam has experienced substantial economic growth since the mid-1980s when economic reform (doi moi) started. However, the Asian crisis had some negative impacts on the Vietnamese economy. Both the external environment and internal competition added more pressure on companies to speed up organizational reform. Transforming the old personnel management into new flexible human resource management system is one of the central reform agendas among companies in order to survive the market competition. This research analyses the nature of the changes in the area of human resource management under the influence of market-oriented reform that puts emphases on flexibility and competitiveness in the new millennium.
