本文利用广义超越对数成本函数,分组研究了我国14家商业银行2001—2010年的面板数据,结果表明:股份制商业银行的总体规模经济略好于国有控股商业银行,但在贷款特定产出规模经济方面要逊于国有控股商业银行;国有控股商业银行的范围经济要好于股份制商业银行,在特定产出范围经济方面,贷款与存款、投资与存款存在成本互补,贷款与投资存在较轻程度的范围不经济。 相似文献

Mobile communications markets worldwide, today, are saturated, the number of mobile network operators (MNOs) in market is declining, mobile revenues are stagnant or falling, MNOs are becoming wireless Internet service providers, and economies of scope are strengthening. This paper challenges existing dominant views on spectrum assignment and license fee payments, estimates spectrum fees that MNOs would have paid under royalties and then compares them with upfront lump-sum fees actually paid by 3G licensees. This paper further proposes that governments need to consider assigning additional spectrum to incumbents as needs arise without using auctions and adopting royalties as a way of collecting spectrum fees should they collect them. 相似文献

The article examines the impact of resale price maintenance (RPM) on market structure, productivity, and competitive advantage in British retail pharmacy. In contrast to influential studies, but consistent with contemporary and recent work, it is shown that the major multiples were able to ameliorate the negative growth impacts of RPM. Higher profit margins ? principally from larger manufacturer discounts and backward integration – were used to fund initiatives aimed at boosting aggregate sales and economies of scale and scope. These relationships are explored using a recently discovered national establishment-level survey of retail pharmacists’ costs and margins, together with internal data for Boots Ltd. 相似文献

We examine whether labour unions influence external auditor selection and audit scope. As a major user group of financial information, labour unions likely demand financial information of high quality and thus high-quality audits. As a union’s request for wage increases is likely strong when a firm is performing well, management facing wage negotiations with the labour union has incentives to manipulate earnings downward and may therefore prefer auditors who allow more discretion. Using union data unique to Korea during 2005–2008, we find that firms with a stronger labour union tend to choose higher-quality auditors (i.e. Big N or industry specialist auditors). We also find that unionization is negatively (positively) associated with positive (negative) abnormal audit fees and audit hours, and the effects are more pronounced when the union is stronger and more active. Given that departures from normal audit fees and audit hours in either direction arguably impair audit quality, this finding is consistent with our prediction of unions’ demand for high-quality audits. Overall, our findings suggest that labour unions play an important role in determining audit quality. 相似文献

The translog cost function is valuable to researchers for empirical analysis in themodelling of indirect cost and profit functions. A flaw of the functional form is in themodelling of zero output values. This study examined the impacts of empirical definition of zero output values on price elasticities, economies of scope and scale, using the translog cost function. Estimation of a system of cost and factor share equations with regularity condition imposed was conducted. Results show that the choice of default values affects policy recommendations. 相似文献

We explore how values for environmental management in the Kimberley region of Australia respond to changes in spatial scale and attribute scope. A discrete choice experiment was conducted that included the impacts of management on marine no‐take areas, Aboriginal rangers, recreational facilities, and coastal development. A split sample single‐site design was used to estimate values for the Kimberley region as a whole, and for two separate smaller sub‐regions, allowing us to test for spatial preference heterogeneity. Management outcomes for different regions were displayed on a map to show respondents explicitly where outcomes would occur. We show that willingness to pay results are similar between the two smaller sub‐regions, and that willingness to pay for the attributes increased when management occurred at the larger geographical scale. However, respondents were somewhat insensitive to changes in the scope of the two cardinal attributes: area of no‐take and number of rangers. We discuss the implications of this spatial and scope insensitivity for choice experiment research. 相似文献

Extending extant literature on geographic scope that has primarily focused on its role in value creation, I investigate the value appropriation aspect of geographic scope of knowledge acquisition. I maintain that isolating mechanisms created via geographic scope of knowledge acquisition can help firms prevent competitors from accessing their innovative knowledge and, by doing so, can help firms capture a larger proportion of economic returns from innovation, thus helping them enjoy better financial performance. Mediating and moderating effect analyses with patent‐ and firm‐level data of the semiconductor industry corroborate the value appropriation aspect of geographic scope.
