Consumption falls counter-factually on impact for investment-specific technology shocks, which, recent literature suggests, are important drivers of business cycles. Introducing financial frictions and variable capacity utilization to the standard New-Keynesian setup can overturn this co-movement problem, without imposing restrictions on wealth effects, or wage rigidities. 相似文献

The oil and gas (O&G) industry suffers from a negative perception of poor sustainability. O&G companies are therefore engaged in several socially sustainable activities related to community development and environmental protection. This article determines whether the social, environmental, and economic dimensions of corporate social responsibility (CSR) are equally value‐additive to O&G companies. We measure the company‐specific level of CSR activities from the information provided in the annual financial reports of O&G companies and determine the effects of CSR dimensions on firm value. We find that CSR enhances firm value of O&G companies. While social activities such as employee well‐being and community development are key value‐drivers, environmental and economic sustainable activities have an insignificant impact on the market value of O&G companies.

Classification is a multivariate technique that is concerned with allocating new observations to two or more groups. We use interpoint distances to measure the closeness of the samples and construct new rules for high dimensional classification of discrete observations. Applicable to high dimensional data, the new method is non‐parametric and uses test‐based classification with permutation testing. We propose a modification of a test‐based rule to use relative values with respect to the training samples baseline. We compare the proposed rule with parametric methods, such as likelihood ratio rule and modified linear discriminate function, and non‐parametric techniques such as support vector machine, nearest neighbour and depth‐based classification, under multivariate Bernoulli, multinomial and multivariate Poisson distributions. 相似文献

This article examines the financial constraint of 18 listed Canadian forest firms between 2000 and 2014 following the stochastic frontier approach. Empirical results support the observation that Canadian forest firms have a strong dependence of using both equity financing and debt financing as the coefficients of both equity and debt financing mean functions are significant at 1% level. The distribution of investment efficiency index (IEI) of all 18 firms demonstrates a loss of around 40% of the rate of investment due to financing constraints. Regional analysis demonstrates that the time-varying patters of IEI of three provinces are significantly different. 相似文献

Background and aims: Infection is a serious and expensive complication of Cardiac Implantable Electronic Device (CIED) procedures. A retrospective based cost analysis was performed to estimate Trust level savings of using the TYRX antibacterial envelope as a primary prevention measure against infection in a tertiary referral centre in South London, UK.Methods: A retrospective cohort of heart failure patients with reduced ejection fraction undergoing Implantable Cardioverter Defibrillator (ICD) or Cardiac Resynchronization Therapy (CRT) procedures were evaluated. Decision-analytic modelling was performed to determine economic savings of using the envelope during CIED procedure vs CIED procedure alone.Results: Over a 12?month follow-up period following CIED procedure, the observed infection rate was 3.14% (n?=?5/159). The average cost of a CIED infection inpatient admission was £41,820 and, further to economic analysis, the additional costs attributable to infection was calculated at £62,213.94. A cost saving of £624 per patient by using TYRX during CIED procedure as a primary preventative measure against infection was estimated.Conclusions: TYRX would be a cost-saving treatment option amongst heart failure patients undergoing ICD and CRT device procedures based on analysis in the local geographical area of South London. If upscaled to the UK population, we estimate potential cost savings for the National Health Service (NHS). 相似文献

The purpose of the present article is to devise an index for measuring and analyzing the divide among countries in the area of information and communication technology (ICT) infrastructure and access. Understanding the fact that there are many factors influencing the digital divide, this research is not intended to measure the digital divide in terms of different inequalities, but it rather attempts to take only one of the most important of these factors (maybe the most important of them) into consideration for measuring and analyzing divide between countries, that is, ICT infrastructure and access. In contrast to the majority of the indices in this context, the proposed index is built upon defining and conceptualizing ICT infrastructure and access. In addition, the index uses core ICT indicators on which the international community and experienced modelers have consensus that they measure the information society suitably. Therefore, the index can be exploited as the basis and standard for internationally comparable statistics in ICT infrastructure and access area. Moreover, it is the second index based on core ICT indicators after the Digital Opportunity Index (DOI) that was developed by the International Telecommunication Union (ITU) in 2005. However, in the current article, using Data Mining methods, Markov Chain Monte Carlo (MCMC) (to impute missing data) and Multi-Stage Factor Analysis (FA) (for aggregating the indicators), many problems and limits of the existing indices, the DOI in particular, such as the lack of data for analyzing ICT infrastructure and access, use of equal weighting or experts’ opinions to aggregate the indicators, are avoided. Since this index is developed by statistical procedures, it is flexible, adaptable, and modifiable over time while it sustains its original structure. It is comprised of two main dimensions: ‘ICT access’ and ‘coverage of mobile and access tariffs’ and 10 indicators. Finally, comparing the proposed index with the other indices in this field and gross national income (GNI) per capita of 150 countries, this index is tested; then, it is utilized to measure and analyze the divide between countries in the two dimensions, different geographical areas, economic conditions, and levels of ICT infrastructure and access. 相似文献

全球化对伊朗、沙特和俄罗斯油气发展战略的影响 总被引:3,自引:0,他引:3
2002年12月9~10日,在第七届伊朗国际能源会议上,来自发达国家和能源专业公司的能源专家们就经济全球化进程对中东油气工业和世界能源供求的影响发表了很多论文,并对世界主要产油国特别是伊朗的政治、法律、经济、金融和能源投资环境等问题进行了研讨。这些论文信息量大、视角独特、分析科学、逻辑性强、立论中肯,对我们实施“走出去”等发展战略有重要的参考作用。本文是此次大会发表的国际能源专家的力作之一,它从全球化的角度阐述了伊朗、沙特和俄罗斯的能源政策动向,有助于我们加深对中东及俄罗斯地区能源地缘政治、大国关系变化的认识,并对未来国际石油市场的发展趋势做出科学的判断。 相似文献

Summary. A basic two-country, single commodity model is considered to formulate the interactive and retaliative policies with regard to restrictions on foreign investment and labor migration. We model quota retaliations using the contingent threat situation. Under three different strategic environments, we characterize the stable quotas on factor movements. Among other things, we illustrate that either one of the two countries may end up with welfare loss- Ramaswami trap, a concept we introduce in this paper.Received: 28 May 2001, Revised: 5 August 2003, JEL Classification Numbers:

We investigate the short‐term relation between individual investor trading and stock returns on the Australian Securities Exchange. Stocks heavily bought by individual investors underperform stocks heavily sold over the subsequent three days, with respective returns on to a long–short portfolio of ?93, ?67 and ?12 basis points on days one, two and three. Individuals underperform in small and mid‐size stocks when they trade passively using limit orders waiting for the market price to move in their favour. Individuals underperform in large stocks when they trade aggressively using marketable orders. Foreign institutions gain from taking the opposite side of individual trades. We present an information asymmetry‐based explanation for the findings. 相似文献

We formulate a model of mergers and acquisitions assuming a monopolistic competitive industry that exhibits agglomeration economies. We provide the conditions for the existence of a non‐trivial Nash equilibrium in the acquisition market at which the most productive firm acquires a range of less‐productive firms. Most importantly, we show that domestic merger and acquisition activities are international trade promotionary. We also show that such types of mergers and acquisition will improve the competitive position of foreign firms leading to an increase in their market share. In addition, domestic mergers and acquisitions will increase the number of imported varieties. 相似文献
