中国企业社会责任博弈分析

本文通过企业、政府、社会利益博弈分析指出,如果没有中央政府的监管,企业与地方政府必然从自身利益最大化出发,做出有损于社会的行为.如果中央政府对企业社会责任治理策略进行选择,其最佳策略是加大对地方政府,而不是对企业的监管.     

事务所地域与其对盈余管理的抑制能力

与西方发达市场相比,我国会计师事务所产生于政府挂靠体制,政府干预过多;上市公司多由国有企业改制而来,国家持股比例较多,上市公司受到当地政府保护等,使得我国的独立审计具有强烈的地域特色,本地事务所多在当地招揽客户,其审计过程明显受到当地政府的干预。鉴于此,我国政府于1999年开始要求会计师事务所与其挂靠单位脱钩,经过这几年的发展,有必要考察目前本地/异地事务所的审计质量差异是否巳消除。本文使用2002—2004年在沪深两市上市的A股公司数据,考察了会计事务所的地域特征对其盈余这理抑制能力的影响。本文使用可操控性应计的绝对值和非经常性损益的绝对值衡量上市公司的盈余管理程度,使用两步回归控制事务所的自选择偏误,结果发现,异地事务所对盈余管理的抑制能力显著强于本地事务所。     

Incentive Complementarity in China’s Rural Enterprises

Complementarity between incentive instruments is a central theme of theoretical research in industrial organization. However, despite its importance, empirical evidence on the existence of complementarities is limited. We identify complementarities between incentive mechanisms using a dataset on rural firms in China. Using a panel regression framework, we confirm that significant complementarities exist in terms of the impact of incentive instruments on the performance of firms. In order to evaluate the robustness of our results we account for unobserved differences in firm quality using fixed effects and instrumental variables regressions. Support for the complementarity hypothesis is found after controlling for unobserved heterogeneity.     

Managerial Firms,Entry, and Switching Costs

Empirical evidence shows that switching costs are important in many industries. We analyze the welfare effects of entry into markets with switching costs when firms can be run by managers and the entrant may be partially foreign-owned. We find that with profit-maximizing firms, the welfare effect of entry depends crucially on the ownership of the entrant firm. We also show that entry is less likely with managerial firms than it is with profit-maximizing firms. In the latter case, entry always reduces welfare if the share of the entrant firm owned by foreign investors is high. However, with managerial firms, entry always increases welfare.     

日本债券市场的发展及对中国的启示

对于始终以间接金融发展为主线的日本来说,资本市场的发展呈现出了较为特殊的轨迹和脉络.债券市场是一国资本市场的重要组成部分.日本债券市场作为一个较为成熟的债券市场,有其自身的发展历程并形成了其自有的特点,如资产担保证券市场发展不充分、证券公司在债券市场上的垄断地位突出、证券市场的监管实施的是统一监管的模式,但显现出分业监管的特征以及债券市场的国际化程度不断提高等.这些特征导致了日本债券市场发展不均衡、日本债券市场缺乏多层次的投资者等诸多的弊端.因此需要采取相应的对策促进日本债券市场的发展.而这些改革的措施同时也是中国债券市场急需借鉴和学习的.     

收入分布、厂商定价与耐用品的消费扩张

本文考察了收入差距对耐用消费品消费的影响。我们从厂商的定价理论出发。说明了收入差距对耐用消费品消费呈现出倒U型的影响：随着收入差距扩大，耐用消费品的消费量增加，但是，收入差距继续扩大则会减少耐用消费品的消费。这说明，适当的收入差距有利于社会消费水平提高和经济的发展，过大和过小的收入差距都无助于经济的起飞。我们最后运用城镇居民和农村居民彩电、洗衣机和冰箱的拥有量对该理论进行了实证检验，实证检验结果基本上支持了我们的理论分析。     

New small firm survival in England

This paper investigates the determinants of the survival, between 2001 and 2004, of 622 small firms in England. Seventy one percent of these firms were less than 5 years old in 2001. Prior work by industrial economists has primarily focussed upon factors such as profitability and exit barriers. In contrast, this paper adopts a more managerial approach by examining whether the human capital of the business owner and organisational variables explain survival and non-survival. Our results suggest the founder’s education and bank finance promote firm survival. Firms which compete on price, or report being financially constrained at start-up, are much less likely to survive.

SCIENCE AND INDUSTRY: TRACING THE FLOW OF BASIC RESEARCH THROUGH MANUFACTURING AND TRADE

This paper describes flows of basic research through the US economy during the late 20th century. In addition, the paper studies the effect of the flows on scientific papers in industries and fields. This article differs from others in its use of measures of science rather than technology. Together, its results present a picture of the structure of basic research flows in a modern, science-intensive economy. Basic research flows are large within petrochemicals and drugs, and within software and communications. Flows of chemistry, physics, and engineering are common throughout all industries – biology and medicine are almost confined to petrochemicals and drugs; and computer science is nearly as restricted to software and communications. In general, basic research flows are more concentrated within scientific fields than within industries. Our findings concerning the production of scientific papers indicate that the effect of a 1% change in academic R&D spillovers significantly exceeds that of industrial spillovers. In addition, within-field effects exceed effects between-fields, while within- and between-industry effects are roughly equal. It follows that scientific fields limit basic research flows more than industries do, perhaps because large firms implicitly span a range of industries.     

企业异质性、贸易成本与服务业生产率

基于异质性企业的内生技术选择视角和世界投入产出表的大样本数据,考察了国际服务贸易成本对服务业生产率的影响。结果表明,更低的贸易成本与更高的生产率及更快的生产率增长相联系,且该效应主要体现在生产性服务部门,但服务贸易成本下降的效应系数远远低于商品部门;对中国样本的检验结果显示,不论是生产性服务业还是生活性服务业,其双边贸易成本下降并未带来服务业生产率及其增长的提升,而商品部门的表现与跨国经验结果一致,我们将该现象称为“中国对外服务贸易成本的生产率效应悖论”,对此提出了3种可能的解释。
