我国金融发展与经济增长关系的区域差异分析——兼论分税制改革对金融发展与经济增长关系的影响

本文利用1979-2003年的省级面板数据，将我国分为东、中、西三大区域，考察了金融发展对经济增长的影响，结果表明：把国有商业银行贷款占GDP的比例作为金融发展的衡量指标对三大地区人均GDP均具有显著的正相关性，金融发展促进经济增长的理论在我国同样成立；但金融发展与实体经济部门之间均不存在良性互动的关系，其对经济增长的贡献仅仅停留在增加资本积累上，对资本配置效率的改善作用不大；1994年的分税制改革对金融发展促进经济增长的作用造成了显著的负面影响。因此，我国的金融体制改革需要将金融体制改革、国有企业改革、财税体制改革和政府体制改革纳入同一个分析框架中进行。     

National culture and R&D and marketing integration mechanisms in new product development: A cross-cultural study between Singapore and New Zealand

The integration of R&D and marketing in new product development (NPD) is an important contributor to NPD performance. Of the mechanisms developed to aid functional integration, many have been developed in western cultural environments and may not have applicability in other national cultural settings. Using a sample of NPD workgroup personnel in New Zealand (NZ), the western cultural environment, and Singapore, quantitative and qualitative data have been used to measure national culture and determine the applicability of different organization integration mechanisms. Results show key differences between the two samples, indicating a link between formalization, centralization, role flexibility and interfunctional climate mechanisms with the Hofstede dimensions of Power Distance, Masculinity and Uncertainty Avoidance of national culture. Managerial implications are that national cultural values and settings of the respondents are important when determining best integration mechanisms.     

Diversification and Capital Structure: Some International Evidence

This study examines the effects of international and product diversification on capital structure with 232 firms from 30 countries. Results for the full sample show that international diversification is negatively related to financial leverage, but further analyses indicate that this is mainly attributable to US firms. For non-US firms, we fail to find a significant relationship. Results also show that product diversification is positively related to financial leverage, indicating that such diversification allows firms to reduce their risks, thereby enabling firms to carry higher debt levels.     

Scientific methods in finance

Computer software can easily produce many financial models with technical skill, but investigators need to interpret and adapt computer output. Such analysis requires a deep knowledge of scientific fundamentals. We argue that an evidential perspective is more appropriate than a decision framework for model selection. We discuss four necessary conditions for any scientific investigation: observables, interpretables, replicables, and robustness in the context of examples familiar to finance professionals. Carefully planning the design of an experiment is the best way to address many econometric maladies. Furthermore, we emphasize the need for more sensitivity testing and for independent replication of empirical results within the finance profession.     

On Quality and Variety Bias in Aggregate Prices

How do product variety and quality affect the aggregate price bias? We develop a general equilibrium model that accounts for the joint interaction of product quality and variety. Our findings show that the aggregate price bias is procyclical and the contribution of product variety is persistent whereas the contribution of product quality becomes countercyclical in the medium to long run. We show that accounting for product quality and variety has critical implications on the measure of cyclical fluctuations. Measurements of cyclical fluctuations derived using the consumption deflator, which abstracts from changes in product quality and variety, underestimate the variables' true volatility.     

Cross‐Firm Real Earnings Management

Our analysis is rooted in the notion that stockholders can learn about the fundamental value of any firm from observing the earnings reports of its rivals. We argue that such intraindustry information transfers, which have been broadly documented in the empirical literature, may motivate managers to alter stockholders’ beliefs about the value of their firm not only by manipulating their own earnings report but also by influencing the earnings reports of rival firms. Managers obviously do not have access to the accounting system of peer firms, but they can nevertheless influence the earnings reports of rival firms by distorting real transactions that relate to the product market competition. We demonstrate such managerial behavior, which we refer to as cross‐firm real earnings management, and explore its potential consequences and interrelation with the practice of accounting‐based earnings management within an industry setting with imperfect (nonproprietary) accounting information.     

Exploring Portfolio Diversification Opportunities Through Venture Capital Financing: Evidence from MGARCH-DCC,Markov Switching,and Wavelet Approaches

Islamic financial institutions are being pressurized by critics to offer profit and loss sharing (PLS) financing, such as venture capital (VC) financing, for the purpose of entrepreneurial development aligned to the principle of equity risk sharing. Our study aims to link PLS investments with portfolio optimization opportunities for the Islamic asset managers. Using portfolio analysis with dynamic conditional correlation, Markov switching, and maximal overlap discrete wavelet transformation, our findings tend to indicate that there is indeed a portfolio optimization opportunity in investment universe for the fund managers who invested in PLS investments in the context of VC asset class over the long run.

Do environmental regulations hamper small enterprises' market entry? Evidence from China

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.
