国外AVM技术在批量评估中的应用

AVM(自动评估模型)是批量评估方法体系的关键技术。本文系统地介绍了AVM的技术原理,并论述了模型设定理论层面与模型校准技术层面以及两者相互的联系,提出了开发和应用国内AVM,建立税基批量评估方法体系的一些构想。     

关于规范发展农村新型金融服务组织的若干思考

为了加快社会主义新农村建设步伐，促进农村新型金融服务组织健康、快速发展，保护投资人或债权人的合法权益，维护农村金融体系稳定，当前，应在相关地区建立农村金融服务协会的试点，各级政府或有关职能部门依托农村金融服务协会，对农村新型金融服务组织履行监督、管理、协调、服务职能，以促进各地农村新型金融服务组织依法办事、合规经营、稳健运行。     

泡沫原油油气分离器的研制

国内油田油井计量普遍采用分离计量方法，用油气分离器把油井采出液分离成液体和气体，然后用仪表分别计量。塔河油田六号油区原油粘度高，密度大、超泡严重，自然消泡时间长，传统的油气分离器处理重质起泡稠油的效率低，分离后的液体含气量较高，造成仪表计量油井产量的误差增大。针对塔河六号油区稠油的特性，研制了泡沫原油油气分离器，介绍了泡沫原油油气分离器的结构，工作原理及现场测试情况，分析了分离器的分离效率对液体计量误差的影响。     

土地面积和地价单位换算的简便方法

由于历史原因,我国土地面积的计量单位在不少场合仍沿用"亩"这个单位.基准地价也往往用"万元/亩"作单位.但我国土地面积的法定计量单位是"平方米".土地面积单位在"亩"与"平方米"之间以及地价在"万元/亩"与"元/平方米"之间的换算,还是土地价值评估中经常要遇到的事情.     

采用风险导向审计时需解决的几个问题

2003年10月,国际审计与鉴证准则委员会(IAASB)通过了新的审计风险准则。中注协也在2004年10月发布了修订后的审计风险准则征求意见稿。审计风险准则征求意见稿的发布不仅将使我国的审计风险准则与国际接轨,同时也为提高审计质量、降低审计风险提供了技术支持。然而,我国当前在采用风险导向审计时有几个问题急需解决,笔者拟从信息库的建设、注册会计师的知识结构、分析性程序、辅助审计软件的建设等方面对此进行一些尝试性的探讨。     

Enterprise Risk Management and the Cost of Capital

Enterprise risk management (ERM) is a process that manages all risks in an integrated, holistic fashion by controlling and coordinating any offsetting risks across the enterprise. This research investigates whether the adoption of the ERM approach affects firms' cost of equity capital. We restrict our analysis to the U.S. insurance industry to control for unobservable differences in business models and risk exposures across industries. We simultaneously model firms' adoption of ERM and the effect of ERM on the cost of capital. We find that ERM adoption significantly reduces firm's cost of capital. Our results suggest that cost of capital benefits are one answer to the question how ERM can create value.     

Competitive pricing strategies in social networks

We study pricing strategies of competing firms selling heterogeneous products to consumers. Goods are substitutes and there are network externalities between neighboring consumers. In equilibrium, firms price discriminate based on the network positions and charge lower prices to more central consumers. We also show that, under some conditions, firms' equilibrium profits decrease when either the network becomes denser or network effects increase. In contrast, consumers always benefit from being more connected to each other. We determine the optimal network structure and compare uniform pricing and discriminatory pricing from the perspectives of firms and consumers.     

Marriage between credit cards and the Internet: Buying is just a click away!

This paper examines whether Internet access positively affects credit card balances. To that end, we compare the 2010 and 2013 Surveys of Consumer Finances, analyze the consistency of the results over time, and provide the rationale for any resulting differences. Using the censored techniques, our results indicate that Internet access has a positive effect on credit card balances, which suggests that consumers with Internet access are prone to higher balances compared to those without. The probability of carrying positive balances was larger in 2010 compared to 2013. Overall, the results suggest that, while the financial crisis might have contributed to higher balances in 2010, the economic recovery afterward seems to have eased the burden of credit card debt.     

Board of Directors and CSR in Banking: The Moderating Role of Bank Regulation and Investor Protection Strength

This paper brings together research on boards of directors as the backbone of corporate governance and corporate social responsibility (CSR) practices in the banking industry. The underlying idea is that some characteristics of bank boards, in particular independence and gender diversity, may impact the CSR commitments of banks. By making use of a sample of 159 banks in nine countries during the period 2004–2010, our empirical evidence suggests that banks with more independent directors and more female members on their boards incline toward socially responsible behaviour. Our results also suggest that institutional factors play a significant role in these effects. They show that in greater regulatory and stronger investor protection environments, board independence and gender diversity have more influence on the social behaviour of banks.
