Patterns of Economic Development and the Formation of Clubs

This study investigates the sources of heterogeneity across a worldwide set of countries. Unspecified ex ante and unanticipated cultural (Protestant versus Catholic), geographical (continents), and institutional (OECD versus non-OECD) clubs emerge endogenously and naturally as homogeneous classes on the basis of their economic structure. The dynamics both within and across the identified groups of countries are consistent with multiple equilibrium-growth models proposed by, for instance, Azariadis and Drazen (1990), therefore strengthening the viability of the convergence club hypothesis. In particular, higher stages of development are, on average, non linearly associated with higher stages of growth.

黑龙江省发展优势产业的基本对策

利用黑龙江省各产业区位商值和影响力系数、感应度系数以及产业关联度系数等指标,采用综合评价方法中常用的指数构造方法,对优势产业进行综合分析得出:目前黑龙江省存在着总体产业优势地位不突出、经济效益不佳、技术进步投入不足等问题。应采取加快老工业基地改造、推进企业生产和组织结构升级、加大农业综合开发力度、大力发展第三产业等措施,以促进黑龙江省优势产业的持续发展。     

Risk and the strategy of foreign location choice in regulated industries

We argue that firms in regulated industries react to macroeconomic and policy risks in sharply different ways. While they seek to avoid countries with high levels of macroeconomic uncertainty, we predict that they find it more attractive to expand into countries characterized by governments with discretionary policymaking capacities so as to be able to negotiate favorable conditions of entry. We also argue that firms are heterogeneous in their attitudes toward risk. We predict that firms in which the state holds a partial equity stake exhibit a more tolerant attitude. We also expect that as firms accumulate foreign experience, they develop an aversion toward further foreign entries into politically unstable markets. Support for these predictions is provided by an analysis of the Latin American market entries of all listed Spanish firms in regulated industries between 1987 and 2000.

城市开发问题的博弈分析

城市开发活动是开发企业与开发企业、开发企业与行政机构的互动行为 ,而城市开发行为的最优选择也是在各类投资主体之间的互动博弈中形成的。先行投资困境、优势区位问题、行政介入问题和可持续开发问题 ,都反映了投资主体博弈的特定后果。从博弈论的角度来思考 ,我们能对城市开发问题的实质内涵有更为深刻的理解。

“免疫系统论”下的国有企业审计定位——基于国家审计的思考

审计是国家经济社会运行的“免疫系统”,国有企业审计在构建国家审计“免疫系统”中具有重要地位。“免疫系统论”下的企业审计应发挥预防性、揭示性和抵御性等免疫功能,应关注国家经济安全,注重对问题和案件的查处与揭露,并着力促进体制和机制的完善与改革。发挥免疫功能需要加强理论建设,完善审计生态环境,培养适应型人才,创新审计方法。
