Market Orientation: Scale Invariance and Relationship to Generic Strategies Across Two Countries

This article presents a scheme for investigating scale invariance for the market orientation construct across different countries by examining the psychometric properties of the operationalisation of market orientation (Narver and Slater, 1990). We investigate the measurement of market orientation in two countries (Australia and Zimbabwe—one being an example of a developed economy, the other of a developing economy). We then proceed to test the relationship between market orientation and Porter's (1980) generic strategies. The results suggest that the psychometric properties of the market orientation construct differ in important respects across countries. However, tests for convergent, predictive and discriminant validity using the generic strategies are fully supported for Zimbabwe while for Australia they are supported mutatis mutandis.

Double implementation in economies with production technologies unknown to the designer

Summary. This paper considers double implementation of Walrasian allocations and Lindahl allocations in Nash and strong Nash equilibria for both private and public goods economies when preferences, initial endowments, production technologies, and coalition patterns are all unknown to the designer. It will be noted that the mechanisms presented here are feasible and continuous. In addition, unlike most mechanisms proposed in the literature, our mechanism works not only for three or more agents, but also for two-agent economies, and thus it is a unified mechanism which is irrespective of the number of agents.

火山岩气藏面临的出水问题及治理对策

随着气田开发进入稳产阶段末期,气井出水带来的开发矛盾日益突出。为此,在认识火山岩储层4种出水类型规律的基础上,开展典型气井生产动态特征分析,明确不同出水类型气井面临的治水难题。通过现场试验,探索出经济可行的治理对策,包括裂缝纵向强水窜型气井连续循环气举、裂缝纵向弱水窜气井智能化泡沫排水采气,以及孔隙纵向水锥和高含水饱和度气层出水气井储层深部解水锁3种治理措施,为火山岩气藏的持续高效开发提供技术支撑。
