Unemployment in Greece: Evidence from Greek regions using panel unit root tests

The purpose of the paper is to examine the nature of Greek regional unemployment. The paper contributes to the literature assessing the stochastic properties of Greek unemployment rate in the context of the Greek regions by relying on various univariate and panel unit root tests. In particular, recently developed and more powerful panel unit-root tests that control for structural breaks, heterogeneity and cross-sectional dependence in the panel are employed. The results show that in all cases, after taking into account the fact that regional unemployment rates in Greece are subject to a structural break, the null hypothesis of a unit root is not rejected, indicating that the Greek regional unemployment series are non-stationary with the presence of a structural break.     

Structural Change in Advanced Nations: A New Set of Stylised Facts*

We provide new evidence on patterns of structural change in advanced economies, reconsidering the stylised facts put forward by Kaldor (1963) , Kuznets (1971) , and Maddison (1980) . Since 1980, the services sector has overwhelmingly predominated in the economic activity of the European Union, Japan, and the US, but there is substantial heterogeneity among services. Personal, finance, and business services have low productivity growth and increasing shares in employment and GDP. By contrast, shares of distribution services are constant, and productivity growth is rapid. We find that the labour share in value‐added is declining, while the use of ICT capital and skilled labour is increasing in all sectors and regions.     

Informal economy, wage goods and accumulation under structural adjustment theoretical reflections based on the Tanzanian experience

Economic development in sub-Saharan Africa under structuraladjustment witnessed the upsurge of informal sector development—thedevelopment of unregulated labour-intensive activities, in partexport-oriented. This paper argues that two factors played animportant role in shaping the dynamics of informal sector development:(1) the process of the relative cheapening of wage goods asa result of their importation, partly financed through foreignaid, thereby lowering unit-labour costs in labour-intensiveproduction, and (2) the processes at work of subsidising realwages by other forms of economic security as a result of multiple,diversified and spatially extended livelihood strategies. Whilethese factors undoubtedly brought a new vitality to economicdevelopment, this paper questions the long-run sustainabilityof this new trend for two reasons. One is its dependence onforeign aid to finance imports. The other is that it does notappear to propel endogenous increases in productivity by achievinggreater synergy in intersectoral linkages between agricultureand industry.     

国有企业与非国有企业信贷约束的差异研究——基于现金一现金流敏感度的分析

根据现有理论,国有企业和非国有企业信贷约束的差异是理解中国经济失衡的关键,本文利用近年来公司金融文献中提出的现金一现金流敏感度的分析方法,以中国A股上市企业1990—2010年的数据为样本,研究了中国国有企业与非国有企业存在着的信贷约束差异。其基本计量模型回归结果表明,非国有企业的信贷约束更强,而国有企业则不存在信贷约束。随后,采取的稳健性检验结果表明非国有企业受到了信贷约束,而国有企业则没有受到信贷约束这一结论具有稳健性。     

中国药品广告违法问题探讨

由于药品的特殊性,故人们在日常生活中往往难以获取相关的药品知识,药品广告封指导合理用药、安全用药起着至关重要的作用。所以真实合法的广告宣传对药品的推广使用,能起到有效的促进作用,否则将误导消费者。笔者试图对此做出具体的分析。     

Toward a structural view of co-opetition in supply networks

Co-opetition, or simultaneous competition and cooperation, in the supply chain management literature has been treated as a dyadic relational phenomenon where the buyer's strategy is considered to be the primary driver. In this paper, we move beyond the dyadic view and propose a theory of co-opetition in supply networks. We argue that as firms within a supply network interact over time to access, share, and transform resources, new ties between firms are formed and existing ties dissolve, giving rise to co-opetition dynamics at the network level. Taking a configurational approach, we employ the inter-related dimensions of ties between firm, firm-level task, network-level objective, and governance to specify four practical supply network archetypes that cover a wide range of economic activities. We then explain how coopetitive relationships may evolve in these supply network archetypes. Specifically, we discuss how relationships form or dissolve in these archetypes and how local structural changes lead to co-opetition dynamics at the network level. We also discuss the implications of such dynamics from a managerial perspective.

Does aging influence structural change? Evidence from panel data

Our study represents a first attempt to single out the effects of aging on the entire structure of the economy that is approximated by employment shares in different sectors. We find that even after controlling for the effects of other relevant factors - e.g., income per capita, share of trade in GDP, government consumption share in GDP, population size - aging does have a statistically significant differentiated impact on the employment shares. In particular, we find that an increase in aging exerts a statistically significant adverse effect on the employment shares in agriculture, manufacturing, construction, and mining and quarrying industries. At the same time, an increasing share of the elderly (decreasing share of the youth) in society positively affects employment shares in community, social, and personal services as well as in the financial sector.     

Global imbalances and dynamics of international financial markets

We provide an overview of the special issue “Global Imbalances and dynamics of international financial markets”. This special issue, which is associated with the 7th International Finance Conference, features research papers dealing with the impact of global imbalances, market complexity, and the impact of the recent global financial crisis on the conduct of monetary policies, financial market dynamics, financial stability, and risk management models.     

中国经济增长的周期性波动研究及其产业结构特征(1992～2010年)

本文使用基于贝叶斯方法的结构突变模型,研究了1992～2010年我国经济增长的周期性波动特征。研究发现,该阶段我国经济增长分别经历了一次六阶段的U形中长周期和一次三阶段的V形短周期,国际经济环境的变化对我国经济的影响日益显著,同时经济增长的波动存在季度性。通过对三次产业GDP增长率的分析,我们还发现三者之间存在着较大偏离,第二产业对我国经济增长的周期性波动起着决定性的影响,同时第二、第三产业之间的关联性在不断增强。
