Contextual factors affecting the integration of enterprise systems in post-merger oil and gas companies

This study examines the contextual factors of the external business environment, organization, information systems, and enterprise system software as they affect integration of enterprise resource planning (ERP) systems after a merger or acquisition in the oil and gas industry. A multiple case study method using primary and secondary data revealed: ERPs are operational necessities rather than strategic differentiators; best practice adoption is a viable alternative that supports successful integration of cultures and knowledge from two experienced organizations; schedules are extended when best practices from both companies are consolidated into a single instance; consolidation facilitates Sarbanes-Oxley compliance and lowers the cost of ownership; imposing acquirer systems on targets facilitates timely decision-making and shorter schedules.

Multiproduct price competition with heterogeneous consumers and nonconvex costs

This paper extends the oligopolistic model of price competition to environments with multiple goods, heterogeneous consumers, and arbitrary continuous cost functions. A Nash equilibrium in mixed strategies with an endogenous sharing rule is proven to exist. It is also shown that, in environments with fixed costs and constant marginal costs, all (symmetric and asymmetric) equilibria exhibit price dispersion across stores. Furthermore, the paper identifies scenarios in which prices will necessarily be random. In these markets, stores keep each other guessing because, given the fixed costs, they would incur a loss if their price strategies were anticipated and beaten by competitors. This is interpreted as an important economic feature that is possibly behind random price promotions such as weekly specials.

成渝同质化竞争与化解

成渝两市在合作与发展的同时,也出现了同质化竞争的倾向,表现出产业趋同化特征。市场机制具有导向同质化竞争的倾向,因而同质化竞争是市场经济发展的常态现象。鉴于此,成渝两市应在市场经济环境下理性处理竞争与合作的关系;充分发挥市场机制的作用,让资源和要素在成渝两市之间自由流动;推进同质化中的差异化,促使产业结构同中有异;推动两市的自主创新,发展各自的核心技术,通过核心技术带动对各自产业发展进行定位,以规避产业趋同中的恶性竞争。

关于相互促进的国内国际双循环思考

疫情下的世界经济复苏困难重重,民粹主义、反全球化逆流泛起,党中央此时提出的国内国际双循环决策具有重大的战略与历史意义。如何应对新挑战,需要搭建一个怎样的框架才能打通双循环？特别是在数字化大潮下如何作为？本文认为,应当在畅通要素循环的“一线”,聚焦高科技与高质量消费“两大制高点”的框架下,依托数字化大潮催生新发展动能、深化改革、扩大开放、推动共建共治共享,使数字经济沿着数据的藤蔓延伸至双循环的每一个节点,助力技术替代,攻克“卡脖子”的堵点,满足人民群众高质量消费需求,为新发展格局下的中国经济发展奠定坚实基础。

Type A behaviour at work – an empirical study of Taiwanese managers and entrepreneurs

Bortner's Type A Behaviour Questionnaires were used to explore the work behaviour of Chinese managers and entrepreneurs in Taiwan and to investigate how that behaviour was influenced by occupation, age and gender. One hundred and seventeen subjects participated in the study, of which 45 were also interviewed. The mean score on the questionnaire was 74.68, the median (74) and the mode (76) within a scoring range of 0–140. Eighty-four subjects registered scores of 80 or less (Type B behaviour) and 33 came within the mid-range of 81–120. None of the subjects registered scores of 121–40 (Type A behaviour). The highest score of 113 was registered by a female bank vice-president and the lowest (47) by a male manager working in a charitable organization and about to retire. The results are discussed within the context of Chinese cultural traditional and parenting practices, the unique characteristics of Taiwan's recent history and the subjects' career experience.     

Comparing Public and Private Sector Employees’ Innovative Behaviour: Understanding the role of job and organizational characteristics,job types,and subsectors

Abstract

Innovation is argued to be of key importance in the public sector. Little is known about possible sector differences in innovative behaviour. The stereotype in literature is that public employees are less innovative. We analyse whether sector is associated with innovative behaviour and the influence of job/organizational characteristics. We test this by using a three-country representative survey in Scandinavia with 8,310 respondents. We control for subsectors/industries and job functions. We do not find that public employees are less innovative. Furthermore, the study emphasizes the importance of understanding the major differences in innovative behaviour between different subsectors/industries and job types.
