The present inquiry lays a groundwork for the analysis of the net greenhouse gas (GHG) footprint of oil in the oil-abundant settings. To address the research question, the study puts forward a three-sector decision model, which provides a common ground for the assessment of the interaction of the structuralist and institutional factors influencing environmental pollution in the oil-reliant economies. The study shows that fossil-fuel abundance triggers forces, which induce diametrically opposed effects concerning atmospheric pollution. These are the rising carbon-intensive oil extraction and processing and fossil-fueled power generation versus shrinkage of the carbon-intensive manufacturing and growth of the low-carbon tertiarization. The theoretical analysis enables compartmentalization of the essential factors, which determine GHG emissions in the respective countries. To assess the significance of the proposed theoretical framework, the study employs multivariate panel co-integration techniques and two-stage fixed effects estimations for a dataset of 38 oil-producing countries for the time period between 1960 and 2018. In contrast to the existing literature, this study drives apart from the black box approaches that employ just one omnibus variable, per capita income. 相似文献

We develop a supply-demand model for the public sector with a political equilibrium. The model considers the inefficiencies caused by taxes and includes costs associated with the provision of public goods to consumers. We show that the size of the public sector may depend on the median voter's income, population size, costs associated with paying tax, and quality of institutions, all of which reflect the costs of provisioning public goods. The estimates for the Organisation for Economic Co-operation and Development member countries are compatible with theoretical predictions; however, they do not confirm Wagner's law, which holds that the public sector share does not grow with an increase in income. A greater dependency ratio and the Gini coefficient increase demand for redistribution policies. Greater government effectiveness is a supply-side factor that increases the public sector's share in an economy. 相似文献

Supply chain management (SCM) has been recognised as key to automobile manufacturers’ (‘buyers’) competitive advantage. However, the performance implication of two different approaches towards SCM, obligational contracting (OCR) vs. arm’s length contracting (ACR), remains inconclusive in the current literature. By focusing on examining how multiple global automobile manufacturers’ SCM practices result in different performance outcomes in the one-country setting of Australia, we are able to ascertain the direct impact of SCM approaches on buyers’ performance. We also provide detailed analysis on the specific influence of each distinguishing feature of the OCR/ACR approaches on different aspects of performance. Through a more nuanced investigation of the links between SCM approaches and automobile manufacturers’ performance at the firm level, this research contributes to a better understanding of the topic with managerially applicable insights. 相似文献

We propose the notions of mixed and behavioral Ellsberg strategies for extensive form games and prove that these strategies are outcome-equivalent if and only if mixed Ellsberg strategies satisfy a certain rectangularity condition. In addition, we show that not only the profile of Ellsberg strategies must be appropriately chosen but also the extensive form must satisfy further restrictions beyond those implied by perfect recall in order to ensure that each player will respect his ex ante strategy choice with the evolution of play. 相似文献

Debreu’s coefficient of resource utilization is freed from individual data requirements. The procedure is shown to be equivalent
to the imposition of Leontief preferences. The rate of growth of the modified Debreu coefficient and the Solow residual are
shown to add up to TFP growth. This decomposition is the neoclassical counterpart to the frontier analytic decomposition of
productivity growth into technical change and efficiency change. The terms can now be broken down by sector as well as by
factor input.

由于法律规范“技术内容”强制实施模式认识的错位、标准体制改革的滞后和《标准化法》修订的延迟,造成了我国强制性标准概念的误解和性质认定的分流。运用行政权力、通过行政手段强制实施标准,引起强制性标准亦“法”“非法”的性质争议;由于对标准与法、强制性国家标准与自愿性国家标准、强制性标准与技术法规的关系认识不清,引发了强制性标准一系列困境的生成。为克服困境、化解危机,应结合我国具体国情进行方案设计和路径选择,通过一系列因素的综合考量,优先确立改良式方案,并通过《标准化法》的修订加以体现。 相似文献

This paper studies two novel productivity characteristics of foreign acquisition on high-tech manufacturing firms: the dynamic and the non-Hicks-neutral effects. A dynamic productivity effect of foreign ownership arises when adoption of foreign technology and management practices takes time to fully realize. Furthermore, these dynamic adjustments may be capital or labor augmenting as adoption of advanced production technologies tends to have non-neutral productivity implications in developed countries. We propose and implement an econometric framework to estimate both effects using firm-level data from China's manufacturing sector. Our framework extends a nonparametric productivity framework, in which identification is achieved using a firm's first-order conditions and timing assumptions. We find strong evidence of dynamic and non-neutral effects from foreign ownership, with significant differences across investment sources. Investment from OECD sources is found to provide a long-term productivity boost for all but the largest recipients, while that from Hong Kong, Macau, and Taiwan does not raise performance. These findings have implications for China's declining labor share and for the rising domestic value-added content of its high-tech exports. 相似文献

In this paper, the maximum determinant of the associated 0-1 matrix in D-Optimal saturated main effect plans for 3× s_2 ×
s_3 factorials, is derived by the use of Graph theory and Combinatorics. The present work is related to a problem suggested
by Chatterjee and Narasimhan (2002). Using the theoretical results, we also give the designs for s3≥s2 + 1.
