This paper highlights the effect of firms’ position on firms’ strategies with corporate social responsibility (CSR) practices under three different cases: Cournot competition; Stackelberg competition with the CSR firm taking the leader position and turnover, with the profit maximising (PM) firm playing as the leader. Some interesting conclusions are achieved. First, the CSR firm always produces more than the PM firm. Second, the outputs of both firms (the consumer surplus) under the PM firm's leading position are larger than those under Cournot. Third, the profits of both firms (producer surplus) under the PM firm playing the leading position are less than those under Cournot. Surprisingly, when the PM firm first moves, the PM firm's profits are the lowest while the CSR firm's outputs are the highest in all three cases. Finally, the relationship of social welfare under the three cases is ambiguous. 相似文献

FDI对高新技术产品出口比较优势的影响分析 总被引:3,自引:0,他引:3
改革开放30年来,中国吸收外资取得了举世瞩目的成就,外商直接投资(FDI)对我国的贸易,特别是对高新技术产品出口的贡献作用非常大。文章采用线性回归模型进行实证分析,得出FDI作为解释我国高新技术产品出口竞争力提升的解释变量是显著的,特别是滞后一期的FDI对我国高新技术产品出口竞争力的影响更明显,并根据该结论为发展我国高新技术产品出口提出建议。 相似文献

AbstractBackground: The prevalence of nontuberculous mycobacterial lung disease (NTMLD) in the US has increased; however, data characterizing the associated healthcare utilization and expenditure at the national level are limited.Objective: To examine associations between economic outcomes and the use of anti-Mycobacterium avium complex (MAC) guidelines-based treatment (GBT) for newly-diagnosed NTMLD in a US national managed care claims database (Optum® Clinformatics® Data Mart).Methods: NTMLD was defined as having ≥2 claims for NTMLD (ICD-9 031.0; ICD-10 A31.0) on separate occasions ≥30?days apart (between 2007 and 2016). The cohort included patients insured continuously over a period of at least 36?months (12?months before initial NTMLD diagnostic claim and for the subsequent 24?months). Treatment was classified as GBT (consistent with American Thoracic Society/Infectious Diseases Society of America guidelines), non-GBT, or untreated. All-cause hospitalization rates and total healthcare expenditures at Year 2 were assessed as outcomes of the treatment prescribed in Year 1 after NTMLD diagnosis.Results: A total of 1,039 patients met study criteria for NTMLD (GBT, n?=?294; non-GBT, n?=?298; untreated, n?=?447). After adjustment for baseline characteristics, GBT was associated with a significantly lower all-cause hospitalization risk vs non-GBT (odds ratio [OR]?=?0.53; 95% CI = 0.33–0.85, p?=?0.008), and vs being untreated (OR = 0.57; 95% CI = 0.35–0.91, p?=?0.020). Adjusted total healthcare expenditure in Year 2 with GBT ($69,691) was lower than that with non-GBT ($77,624) with a difference of ?$7,933 (95% CI = ?$14,968 to ?$899; p?=?0.03).Conclusions: Patients with NTMLD in a US managed care claims database who were prescribed GBT had lower hospitalization risk than those who were prescribed non-GBT or were untreated. GBT was associated with lower total healthcare expenditure compared with non-GBT. 相似文献

Industry-region Position and Economic Performance of Travel and Tourism Service Industry: An Agglomeration Perspective 总被引:1,自引:0,他引:1
Numerous studies have attempted to examine industry performance from an agglomeration perspective. However, many are still focused on the manufacturing sector. This study examines the travel and tourism service industry's economic position using an agglomeration perspective and whether this relates to its economic performance. This study discovered that, apart from being related to its intra-region position relative to other industries within the region, the economic performance of an industry in a region is also related to its intra-industry position relative to other distributive regions within the industry and to its national geographical concentration. A more significant finding is that regardless of either the intra-industry or intra-region position of the industry in a region, enhancing agglomeration not only increases competition and profit erosion but also improves labour productivity. For employment creation, it is more effective to develop an industry with more uniform national geographical distribution. 相似文献

Corlu and Corlu [Quant. Finance, 2014, doi: 10.1080/14697688.2014.942231] provided a novel modelling of exchange rate data for nine currencies using five flexible distributions. They stated that the generalized lambda, skew t and normal inverse Gaussian distributions ‘do a good job’. Here, we reanalyse the data and show that a distribution simpler than all of these fits at least as well as these distributions. We also find that the normal inverse Gaussian distribution provides good fits for only one of the data-sets. 相似文献

The classical ratio estimator is one of the auxiliary information estimators frequently discussed in the audit sampling literature. The major weakness of this estimator is its unreliability when accounting populations have only one-sided errors or when the error rate is low. Efforts have been made to improve the classical estimator by using techniques such as the Jackknifed ratio discussed by Frost and Tamura (1982). This paper proposes a new method to estimate the population total error based on the ratio of error over book value, i.e., taintings. The special features of the proposed procedure are that (1) it specifically models the special characteristics of the typical accounting populations, and (2) it is the first study we know of in the audit sampling literature that uses simulation to capture the characteristics of the specific distribution of the estimator each time a confidence interval is constructed. This new approach became possible because of the recent publication of several studies on the empirical characteristics of accounting errors. Results of empirical tests indicate that the proposed method can significantly improve the reliability of the classical ratio under circumstances where the classical ratio needs improvements. Empirical comparisons are also made with a third ratio estimator under dollar-unit sampling. Again, the proposed method provides better reliability. 相似文献

This study analyses the patent trends and volatilities for the top 12 foreign patenting countries in the US market from 1975 to 1997. Japan is ranked first in terms of foreign patents registered in the USA, followed by Germany. Patent registrations from each of these countries have increased steadily over time, but at different rates. Using monthly time series data for 1975–1997, the time-varying volatility of Australian, Japanese and German patents registered in the USA is examined in detail. The asymmetric AR(1)-GJR(1,1) model is found to be suitable for Australia and Japan, while the best fitting model for Germany is the symmetric AR(1)-GARCH(1,1) model. 相似文献

The recent proliferation of computer networks has stimulated the emergence of thousands of online communities. Facebook, which has grown to 175-million users in five years and recently surpassed megasite MySpace to become the world's largest social networking site, is a classic example. As the importance of online communities continues to grow, a good understanding of their success factors for building and sustaining a community becomes crucial. In this article, we apply social capital theories to examine the interactions among individuals and trust building at the initial development of an online community. Specifically, we postulate that offline social capital can be transplanted into an online community (small or large) to foster the development of trust and social norms that make a community thrive. We conduct two experimental studies: one in the context of real-world, small-scale online communities, and the other in the context of computer-simulated large-scale online communities. Results from these studies provide strong support for our proposition. We interpret these results and discuss their implications and contributions to theory and practice. 相似文献
