Some Potential Linkages for Input-Output Analysis with Flow-of-Funds

Three major, interrelated accounting statements, at the frontiers of quantitative economic analysis, are three interrelated systems, namely: (1) National income and product accounts (NIPA), (2) The input-output tableaux, (IO), and (3) flow-of- funds accounts (FF). The third-mentioned system is somewhat less available and used in only limited areas of macroeconomic analysis. This paper is mainly concerned with use of FF accounting systems. This system shows where financial resources originate, and where they go in support of real capital formation. In this respect, interest rates and other market-based financial rates are of key importance. While much macroeconomic analysis is based on the rates that fit the yield curve, showing the interest rate structure over various maturities of debt associated with a given degree of risk. In contrast, the FF accounts throw light on the whole spectrum of interest rates, across maturities and debt qualities. For example, in analysis of the real estate market and funding of capital formation there, it is important to have a full understanding of the course of mortgage rates of different maturities and qualities. In short, it is necessary to develop a full appreciation of supply and demand forces in the mortgage market, which often is not obviously related to movements of the operative rate for monetary policy, such as very short-term inter bank rates or call money rates. This paper attempts to provide material from the flow-of-funds accounts that would make it possible to analyze the movement of relevant mortgage rates or whatever other rates are needed to understand the financing of capital formation in real estate.     

社会预测体制的生成与演变

预测活动是现代人类活动的基础,科学地预见未来与人类的命运休戚相关。该文在梳理预测体制形成的历史流变的基础上,着重探讨了现代预测体制的确立及其在领导体制中的重要地位,特别是现代预测体制中的国家预测系统已成为国家安全的重要依托之一。正是由于各国建立了日趋完善的预测体制,现代国际政治关系才得以形成并稳定下来。现代预测体制正朝着控制整个社会体制的方向发展。现代社会中所有机构的决策却越来越依赖于预测;社会体制的改革是预测体制行为新范式的灵魂。     

中国区域资本配置效率及区域资本形成影响因素的实证分析

本文构建了32组包含中国各行业近11万个数据的大型面板数据集,分行业系统测算了我国各区域的资本配置效率,并对区域和省际资本形成影响因素进行了系统的比较分析。研究发现:从短期来看,我国各地区的资本形成更加依赖于金融机构贷款的支持;绝大多数省份的资本形成存在自我约束、收敛的机制;不同省份间金融要素对固定资本形成的影响存在较大差异,说明我国地区之间存在一定程度的资本流动障碍。     

资本形成路径与资本存量调整模型——基于中国转型时期的分析

本文综合考察了我国生产性资本的总量水平、形成路径及其调整机制。通过改进的方法所估算的资本存量在改革开放以来已经翻了不止两番 ,年平均增长率为7 3 6 % ,积累极为迅速。资本形成路径明显分为两个阶段 ,增量改革推动的配置效率改进使资本—产出比率在 1 994年之前持续下降 ,而近年来的资本形成过快是由于经济增长越来越倚重资本深化 ,必须通过全方位结构调整加快转型进程。本文进一步给出了我国转型期资本存量调整的供求决定框架 ,实证结果表明 ,需求导向的资本存量调整机制和投资行为已经在中国的转型经济中基本形成 ,产出水平与资本成本均为资本调整与投资需求的主要决定因素     

A comparative analysis of perception of dividends by financial managers

This paper is a report about the perception of dividends by Chief financial officers (CFOs). The research encompasses five countries, on three continents, and covers three types of economies. Our cross-sectional study is concerned with both inter- and intra-societal differences that may or may not exist regarding the perception of dividends by those who are in charge of making such decisions in the firm. Using a survey instrument, we find that both similarities and dissimilarities exist inter- and intra-culturally. Perhaps the most important conclusion we reach is that dividend research must take a different track than it has been following so far.     

Tracking Can Be More Equitable Than Mixing

Parents and policy‐makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity. I answer this question by analyzing the influence of peers on future educational results. I define an equal opportunity policy as one that maximizes the average lifetime income of the worst‐off type of individuals in society (i.e., students from disadvantaged backgrounds). I find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high.     

National culture, networks and ethnic entrepreneurship: A comparison of the Indian and Chinese immigrants in the US

This paper uses a combination of national cultural frameworks and social capital theory to explain the formation and management of entrepreneurial ventures among immigrant communities. The varying rates of venture formation and performance among different ethnic groups points to the role that the different dimensions of culture play in how immigrants use their social networks to start such firms. We use the specific example of the Indian and Chinese communities in the US to demonstrate this effect and explain how businesses created by members of these communities could have potentially different ways of starting and operating that can be directly traced to the differences in cultural orientation of their owners. What emerges can be summarized as: (a) different immigrant communities have different ways of accumulating and using social capital in starting and managing their ethnic ventures; (b) these dissimilarities manifest themselves in variations in the motives for forming these ventures, human resource practices and termination rates; and (c) that these variations can partly be explained by the differences in their respective national cultures.     

论数据分组的误导作用

对数据分组之后再进行处理是一种常见方法,但是这种方法可能产生错误结果.本文搜集了几个实际的数据分析案例,说明对数据的分析可以是任意的,但是对分析结果的解释必须受制于研究对象和周围条件.本文结合案例提出了一些避免分组陷阱的手段,还提供了理解辛普森悖论的一个角度.

Optimization of postal express line network under mixed driving pattern of trucks

Details about the movement of trucks on postal express lines are investigated to improve the performances of mail distribution. A mixed driving pattern of trucks is introduced to minimize the transportation cost of a postal express line network with a service level requirement. We formulate this problem as a mixed p meeting depots location with shipment scheduling problem and build a MINLP model. A two-level tabu search procedure based on shipment grouping method is developed. Through a series of computational experiments and sensitivity analysis on different instances, some managerial insights of the network under mixed driving pattern are revealed.
