A protectionist foodgrain price policy : The case of rice in Panama

Panama has pursued a protectionist price policy for rice, with domestic prices well above the world market level. The government marketing authority purchases sufficient rice to support the established price level and stores or exports the surplus. Although producers benefit, this policy imposes significant costs on consumers, government expenditures and economic efficiency. One policy recommendation is to bring domestic prices in line with the international level. Although free trade is one possibility, a market stabilization programme could be retained. At a minimum Panama's rice price should reflect domestic demand and not production costs. The unfavourable rice-fertilizer price ratio also deserves attention.     

NNS模型及其对宏观经济学的新发展

20世纪80年代以来，新兴新古典综合（NNS）模型被广泛运用于解释具有微观基础的宏观经济问题。本文考察NNS模型的总体研究工作，论证其对于当下宏观经济学的新发展及意义。NNS模型分析性地说明：价格稳定将继续作为好的货币政策的基础，保证货币政策达到家庭福利最大化；在实际操作中，通过锚定预期未来通货膨胀，利率政策通过促进价格稳定的可信性强化了杠杆作用，导致利率政策在最大程度上促进了当前的总需求；只要现金优先的解释暗示了如果价格下降，产出只能增加，那么可以发现，扩张型的财政政策必然会在货币外生的体制下产生通货紧缩的后果。NNS模型对于中国经验具有一定的解释力。     

The impact of cognitive age on Internet use of the elderly: an introduction to the public policy implications

Despite the growth of the Internet, one area that has not really been discussed is the elderly's use of the Internet. Given the rapid growth of this population as well as the potential the Internet holds for them, it is a subject worth consideration. However, seniors cannot be defined simply by their chronological age, but by their cognitive age. This paper discusses the impact of cognitive age of a national random sample of American elderly consumers on their Internet use. The results suggest that those seniors with a younger cognitive age use the Internet more than those seniors with an older cognitive age. Additionally, seniors with a younger cognitive age have more social contact off‐line (but not online) than those seniors with an older cognitive age. Finally, in terms of demographic variables, chronological age is positively associated with cognitive age and women report a younger cognitive age than men. These results suggest that for policy makers interested in increasing the participation of seniors, they can utilize the Internet to reach those who are younger in terms of cognitive age; however, they will not be able to reach all seniors in this manner and they need to utilize the Internet as a complementing media to their traditional communication sources.     

Monetary and fiscal policy interactions in a New Keynesian model with capital accumulation and non-Ricardian consumers

The paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption, government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics. The key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics. Specifically, we identify bifurcations associated with threshold values of steady-state debt, leading to qualitative changes in the local determinacy requirements.     

资产证券化对美国货币政策信用传导渠道的影响研究

本文通过分析美国资产证券化发展前后时期货币政策的效率,证明了货币政策对宏观经济变量的影响程度确实在减弱,从而证明因资产证券化的发展,信用渠道在货币政策传导机制中的作用在弱化。     

发展中国家的竞争政策与产业竞争力培养

一般而言.竞争政策是一国产业竞争力的制度基础,但发展中国家产业发展的基础和国际竞争环境使发展中国家政府注重运用选择性干预作为产业竞争力培养的手段,这种选择性干预与竞争政策存在矛盾和冲突.导致了发展中国家竞争政策与竞争法价值与目标的多元化,造成了竞争机构效率低下及竞争法司法裁决的不确定性.发展中国家的竞争机构应当坚持将维护和促进竞争作为竞争政策的价值,将经济效率作为竞争政策的目标.同时通过设定特殊豁免为政府的选择性干预预留空间,并降低这种选择性干预的随意性,从而使竞争政策在产业竞争力培养过程中发挥应有的积极作用.     

Tourism Policy Making:: The Policymakers’ Perspectives

This research explores tourism policy making, from the perspectives of policy makers using grounded theory. It focuses on Leeds, a city in the North of England, which is characterized by its turbulent environment. The paper identifies themes around policy making, including low status, lack of clarity, uncertainty, lack of consensus and congruence and complexity. Its findings indicate policy making is essentially a social process, involving communication and negotiation between people in the context of wider change. It suggests a social conceptualization, and further research to investigate the communications involved in producing policy rather than the focus on the tangible outputs of the process such as a plan or a physical development.

企业并购估值中的威斯通模型扩展研究

威斯通模型是企业并购估值贴现现金流模型中具有代表性的研究。在威斯通固定增长模型的基础上,建立了考虑未来经营失败概率的估值模型;对威斯通超常增长而后无增长模型进行了修正,探讨了企业在超常增长期采取不同投资策略对其价值的影响,建立了一个更为简明的估值模型,并给出隐含超常增长期限的一种计算方法。
