Industrial Concentration,Output, and Trade: An Empirical Exploration

This paper explores the relationship between concentration, output and trade usingtheory and empirical analysis of matched data on 82 manufacturing industries in seven countries. It finds that the higher is domestic concentration in an industry compared to international concentration, the lower is the domestic share of world output and thesmaller are net exports. This relationship persists even when industries with high levelsof concentration are excluded.     

Experimental Economics and the Theory of Decision Making Under Risk and Uncertainty

Following a brief review of the main experimental work into the economics of risk and uncertainty, both static and dynamic, this paper reports the results of an experiment testing one of the key assumptions of the theory of dynamic economic behaviour—that people have a plan and implement it. Using a unique design which enables the plan (if one exists) to be revealed by the first move, the experiment was implemented via the Internet on a subset of the University of Tilburg's ongoing family expenditure survey panel. The advantages of using such a set of subjects for the experiment are twofold: the demographic characteristics of the set are known and therefore demographic inferences can be made; the representativeness of the set is known and therefore inferences about populations can be made. The results suggest that at least 36% of the subjects had behaviour inconsistent with the hypothesis under test: that people formulate plans and then implement them. Interestingly demographic variables are unable to explain the consistency or inconsistency of individuals. One conclusion is that subjects simply make errors. An alternative conclusion, consistent with previous experimental research, is that people are unable to predict their own future decisions. The implications for dynamic theory (particularly relating to savings and pensions decisions) are important.     

The Global Determinants of Direct Office Real Estate Returns

We investigate the determinants of direct office real estate returns by analyzing rents, capital appraisals, and total returns. A recently compiled global database of major cities in Asia, Europe, and the United States provides a unique opportunity to give a macro-view on the effects of economic growth and supply and demand factors on nominal real estate returns. The global database provides quarterly observations from 1986 to 1999. To address the smoothness problem of appraisal-based price data and regulated rents, we employ the Generalized Method of Moments to estimate a dynamic panel-data model. The model allows us to combine the cross-sectional and time-series dimension in our quarterly data. We find that gross domestic product, inflation, unemployment, vacancy rate, and the available stock all have an effect on real estate returns.

从国际经济学理论视角看企业竞争优势——兼议国际经济学优势思想的演进

本文通过回顾和分析国际经济学中国际贸易理论和国际直接投资理论优势思想的发展和]进,说明了理论研究可以通过对各种市场结构的细分,把优势分析引入到企业内部,并通过对分工、市场结构与交易费用之间的矛盾关系的深入研究,探讨内生优势与外生优势之间的对立统一关系,而企业竞争优势的培育则是一个建立在企业自身独特能力基础上的、综合利用企业内外部各种比较优势的动态累积发展过程。     

The Determinants of Corporate Trade Credit Policies in a Bank‐dominated Financial Environment: the Case of Finnish Small Firms

This paper examines trade credit policies of small firms operating in a bank‐dominated environment (Finland). We find that creditworthiness and access to capital markets are important determinants of trade credit extended by sellers. The level of purchases is positively correlated with the level of accounts payable. Larger and older firms and firms with strong internal financing are less likely to use trade credit, whereas firms with a high ratio of current assets to total assets, and firms subject to loan restructurings use it more. Negative loan decisions by financial intermediaries increase and a close bank‐borrower relationship decreases the probability that a firm does not take advantage of trade credit discounts.     

WTO环境下贸易摩擦及中国对策

经济全球化趋势的不断加强,世界各国经济交往愈加紧密。由于经济发展不平衡及利益不一致,国家之间贸易摩擦日趋激烈。入世以来,中国与其他国家贸易摩擦频繁发生,已经成为中国对外开放中面临的重大问题。为保证中国外贸出口持续发展,必须在深入研究贸易摩擦产生的背景、发展趋势及其特点的基础上,以增强自身实力为根本,通过采取完善贸易救济体系、加快制度调整和创新、加强技术认证工作、扩大内需等措施,为我国外贸发展创造良好的外部环境。

人口规模与教育资源配置良性互动机制的动态仿真

我国人口规模与教育资源配置形成了恶性循环。以社会宏观动力学为分析框架, 基于2000—2019年面板数据,采用Vensim PLE软件,构建人口规模与教育资源配置互动机制系统动力学模型。研究表明：2024年开始,人口规模下降速度将逐年加快,教育市场将出现结构性萎缩,教育资源投入总量和速度将提高;人口规模对生产水平敏感;教育资源市场配置对人口增速、权力巩固程度、权力中心化程度、物力教育资源敏感。基于研究结论,提出两者良性互动的调适策略：保持经济高质量发展,降低生育养育成本;将生育权还给家庭,全面放开生育;巩固“双减”政策成效,引导教育需求;降低权力中心化程度,利用教育市场优势;加大教育资源投入,促进优质教育资源均衡。     

江西省重要应急物资储备库空间优化配置

气候变化和快速城镇化所引致的各种自然灾害等突发事件时有发生,为减缓这些突发事件带来的后果或损失,需要构建有效的应急管理体系和应急物资储备。针对江西省重要应急物资储备库的布局建设,考虑布局建设多个省级区域库,采用规划布局和优化布局的方式对其进行布局研究,分别应用规划服务指派和优化服务指派两种方式实现重要应急物资的服务指派。研究结果表明,江西省省级区域库的优化布局和优化服务指派方案能有效缩减平均服务距离和最远服务距离,提升应急服务的均衡性和可及性。
