The impacts of international tourism demand on economic growth of small economies dependent on tourism

This paper studies the impacts on economic growth of a small tourism-driven economy caused by an increase in the growth rate of international tourism demand. We present a formal model and empirical evidence. The ingredients of the dynamic model are a large population of intertemporally optimizing agents and an AK technology representing tourism production. The model shows that an increase in the growth of tourism demand leads to transitional dynamics with gradually increasing economic growth and increasing terms of trade. In our empirical application, an econometric methodology is applied to annual data of Antigua and Barbuda from 1970 to 2008. We perform a cointegration analysis to look for the existence of a long-run relationship among variables of economic growth, international tourism earnings and the real exchange rate. The exercise confirms the theoretical findings.     

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.     

成本计量模式与企业成本控制机制研究

成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。     

救助投机、挤入效应与国有企业预算约束硬化

国有银行的＂救助投机＂行为促进了国有企业的＂预算软约束＂和不良贷款的积累。在政府、银行与国有企业之间的长期动态博弈中,由于预算硬约束企业的出现给国有银行提供了改善贷款资产组合的机会,提高了银行在与政府的救助投机博弈中的议价能力,要求政府给予更多的流动性注入,这会产生银行贷款资产中预算硬约束企业贷款占比不断增加的挤入效应。这种挤入效应累积到一定程度,政府的救助将变得非社会最优的,进而政府将停止救助,国有企业的预算约束也随之硬化。     

基于古诺模型的四种市场的社会福利

市场根据垄断程度的不同。可以分为完全竞争、垄断竞争、寡头垄断和完全垄断市场四种类型。基于古诺模型，用博弈论方法研究n个厂商市场情形的总产量、价格、总收益和消费者剩余并把它们归纳为统一的公式。从四种市场情形总产量和价格的特点推出其供给曲线的形状，进而比较其社会福利的状况。研究结果表明，随着垄断性的加强，市场的社会福利会越来越劣，完全竞争市场的社会福利最好，垄断竞争市场次之，寡头垄断市场更次，完全垄断市场的社会福利最差。     

OUTPUT FLUCTUATIONS PERSISTENCE: DO CYCLICAL SHOCKS MATTER?

The aim of this paper is to identify the different sources of persistence of output fluctuations. We propose an unobserved components model that allows us to decompose GDP series into a trend component and a cyclical component. We let the drift of the trend component switch between different regimes according to a first‐order Markov process. To calculate an appropriate p‐value for a test of linearity we propose a bootstrap procedure, which allows for general forms of heteroscedasticity. The performance of the bootstrap is checked by means of a Monte Carlo simulation. Our study concerns the USA. We find that cyclical shocks appear to play an important role on the observed persistence of output.     

浅谈民营企业对监理公司管理模式的探讨

现阶段很多监理公司的发展陷入瓶颈甚至走进了死胡同,而业主对监理公司的管理失也逐渐失望,甚至质疑监理制度的必要性。一些监理公司不仅没有发挥应有的作用,甚至还变成了鸡肋,监理公司自身管理有待提高是其中一方面,业主加强对监理公司管理的技巧也很必要,寻求一套合适的管理模式对业主来说也至关重要。     

政府补助、社会责任与流通企业效率

文章从流通视角出发,理论层面分析政府补助对流通企业效率的影响,探讨企业履行社会责任在政府补助与流通企业效率间可能存在的中介机制,并考察国有企业的调节效应。进一步利用我国沪深两市A股241家上市流通企业2010-2020年的非平衡面板数据进行经验检验,研究发现：(1)政府补助会促进流通企业效率的提升;(2)社会责任在政府补助与流通企业效率的关系中存在中介效应,即政府补助能够使流通企业履行更多的社会责任,并由此推动流通企业效率的提升;(3)国有企业存在直接调节效应和间接调节效应。相较于非国有流通企业,国有流通企业所获政府补助以及履行社会责任对企业效率的提升作用更低。研究为深化流通体制改革,提升流通效率提供了新的经验证据。     

经济差距、研发投入对城市经济增长影响研究--基于江苏省13市的数据分析

本文旨在考察研发投入区际流动能否通过空间知识溢出效应促进区域城市经济增长,以及当经济差距缩小时研发投入对经济增长空间溢出效应变化特征。以江苏省13个地级市为研究对象,运用多种空间计量分析方法,对上述假设进行实证检验。研究结果表明:研发投入区际流动的空间溢出效应对区域城市经济增长呈显著的正向效应;苏南、苏中、苏北研发投入空间溢出效应对区域经济增长影响程度高于总体平均水平。本文结论为促进区域间研发投入合理流动、统筹区域经济协同发展、促进省域经济高质量发展提供政策启示。
