We develop a general equilibrium model that jointly considers the influence of capital accumulation constraints and of labour market frictions on the process of transition. We endogenize the economic and budgetary costs of different government policies and show that, early in transition, governments ought to subsidize state firms. Provided that intertemporal commitment is feasible, this policy limits the initial output fall, which relaxes capital accumulation constraints, accelerates transition, and increases welfare. Moreover, by resorting to indirect – instead of direct – taxes, governments can bring the path of transition closer to the first best. Yet, political pressures may induce a policy of suboptimal subsidization.  相似文献

This essay proposes the concrete view that China's strategy of utilizing foreign capitals to adjust again on the foundation of explaining new characteristics of international capital circulation, namely, expanding the foreign investments of the service trade, strengthening efforts to attract outside investment of the Midwest, attracting trans-corporation's investment, etc., Chinese enterprises actively move towards overseas investment and create the policy environment that can contribute to absorbing the foreign capitals as well as making national economy benefit from it.  相似文献

During and after the Asian crisis, institutional investors and pension funds in Asian financial markets have been confronted with a number of difficulties effecting their performance and the way they carry out their role within the national pension system. We analyze these problems by comparing the actual investment policy of an institutional investor with an optimal investment strategy derived from the insights of modern portfolio theory. We also analyze whether the organizational set‐up of a pension fund allows it to adequately perform its role within the pension system. As an example, we examine the operations of the Thai Government Pension Fund (GPF). We find that allowing international investments and reducing restrictions on equity investments while lowering the implicit requirements for investments in government debt would allow the GPF to further diversify its investment risk and to increase its risk‐adjusted return. We also show that some changes in the governance structure of the GPF would lower the occurrence of conflicts of interest for the management and increase the efficiency of the GPF operations.  相似文献

Hybrid organisations present important theoretical and managerial opportunities. We examine a large Finnish multichain retail organisation in order to identify and understand the challenges of hybrids in a retailing context. We are especially interested in how these complex firms try to maintain a balance between the centralised corporate control and the local autonomy and initiative of their retailers. The governance forms and processes identified in the case organisation are discussed with the help of a proposed conceptual framework. We believe that the identified governance problems and practices in the three different retail chains and especially our recommendations will facilitate the understanding of retail hybrid organisations and the management of hybrids in general.  相似文献

In his 1960 book, Sraffa suggested using a composite commodity,which he called the ‘Standard commodity’, to solveRicardo's search for an invariable measure of value, i.e., astandard capable of isolating the price movements of any othercommodity induced by changes in income distribution. The absencein Sraffa's book of an explicit proof of the invariance propertyof this standard gave rise to many misunderstandings about itsmeaning and its role as an invariable measure of value. In orderto clear up these questions, Bellino (On Sraffa's Standard commodity,Cambridge Journal of Economics, vol. 28, 121–32, 2004)has proposed a ‘proper’ definition of an ‘invariablemeasure of value’, showing that Sraffa's Standard commoditydoes fulfil the requirements of this definition. He claims thatthe fulfilment of this property (but not the constancy of its‘nominal’ price) qualifies the Standard commodityas an invariable measure of value. In this paper, a proof ofthe invariance of the price of the Standard commodity with respectto changes in income distribution is given, and the equivalenceof this property with Bellino's definition of invariance isshown.  相似文献

We examine four issues pertaining to initial public offerings (IPOs) using a survey of 438 chief financial officers (CFOs). First, why do firms go public? Second, is CFO sentiment stationary across bear and bull markets? Third, what concerns CFOs about going public? Fourth, do CFO perceptions correlate with returns? Results support funding for growth and liquidity as the primary reasons for IPOs. CFO sentiment is generally stationary in pre‐ and post‐bubble years. Managers are concerned with the direct costs of going public, such as underwriting fees, as well as indirect costs. We find a negative relation between a focus on immediate growth and long‐term abnormal returns.  相似文献

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect.  相似文献

教育经济学不应只是正规学校教育的经济学,在终身学习的理念下,正规学校教育的结束并不意味着学习步伐的停滞和人力资本投资的终结。教育经济学未来拓展的路径,除了理论基础上的"外延式"发展外,还可以在原有的人力资本理论框架内走一条"内涵式"发展的道路,即强调综合考察人力资本投资的多种途径,特别是教育和培训这两种最主要的人力资本投资形式,让教育经济学走出正规学校教育经济学的固有领地,团结在人力资本理论的名义下,与培训经济学融合,走向人力资源开发研究的广阔天地,惟其如此,才能全面、深入地研究人力资本的经济价值及其实现机制。  相似文献
