中国金融产业集聚与地区工业化——基于2002年—2010年省际面板数据的分析

金融产业集聚在地区工业化进程中发挥着非常重要的作用。通过区位商法的分析发现,我国东、中、西部地区金融产业的集聚程度有着较大差距,其中东部地区集聚度较高,而中西部地区则集聚度较低。面板数据的计量检验结果表明,金融产业空间集聚的差异对我国三大不同地区工业化产生了不同影响。总体而言,银行业集聚对工业化的影响作用最大,而证券和保险业集聚作用则较小,而对于不同地区、不同省份以及不同时期来说,这一作用也存在着差异。因此,可以通过调整金融业的空间集聚格局来促进工业化的发展。     

会计师事务所转制对审计质量的影响研究——来自上市公司的经验证据

通过分析2008-2012年A股上市公司相关数据,研究会计师事务所转制对于审计质量的影响,结果显示：特殊普通合伙制会计师事务所的审计质量高于有限责任制会计师事务所的审计质量;转制后会计师事务所的审计质量高于转制前会计师事务所的审计质量,但是转制对审计质量的提高有一定的不同步性。研究结论为转制政策的合理性提供了证据支撑,也为其他中小型会计师事务所改制提供了必要性方面的经验依据。     

An empirical investigation of firm public and private knowledge

Many studies examine firm private knowledge, but purport to be generalizable to the totality of firm knowledge, both public and private. This study demonstrates that public and private firm knowledge are empirically separable constructs that have significant and yet different influences on innovative outcomes. The example of product development effectiveness within this study shows that both public and private knowledge are significantly related to product development quality; however, public knowledge is negatively related to quality lapses while private knowledge is positively related to quality lapses.

Shadow costs of incomplete information and short sales in the valuation of the firm and its assets

This paper presents a simple framework for the valuation of compound options within shadow costs of incomplete information and short sales. The shadow cost includes two components. The first component is the product of pure information cost due to imperfect knowledge and heterogeneous expectations. The second component represents the additional cost caused by the short-selling constraint. Information costs are linked to Merton's (1987. Journal of Finance 42, 510) model of capital market equilibrium with incomplete information, CAPMI. This model is extended by Wu et al. (1996. Review of Quantitative Finance and Accounting, 7, 136) who propose an incomplete-information capital market equilibrium with heterogeneous expectations and short sale restrictions, GCAPM. This model is used in our paper to provide for the first time in the literature analytic solutions for derivatives in the presence of both shadow costs of incomplete information and short sales.When deriving the compound call option formula, we consider a call option on a stock, which is itself an option on the assets of the firm. Our methodology incorporates shadow costs of incomplete information and short sales on the firm's assets as well as the effects of leverage in the capital structure. The formula can be useful in the valuation of several corporate liabilities in the presence of information uncertainty and short sales constraints about the firm and its cash flows. Our analysis can be used for the valuation of several real options.     

Permit markets, market power, and the trade-off between efficiency and revenue raising

This paper focuses on an emissions permit market dominated by one firm and with a government concerned about social efficiency and permits revenue. In this setting, it is shown that the dominant firm's market power reduces the opportunities for the government to raise non-distortionary revenue from permits without loss of consumer surplus. Since the government's objectives are thus hampered in auctioning permits, the dominant firm should be excluded from the auction. Specifically, the regulator should sell permits directly, through bilateral negotiation, to the dominant firm, and auction off the remaining permits to the fringe firms.
