The impact of external reference price on consumer price expectations

Comparative pricing practices are frequently used where actual product prices are accompanied by higher external reference prices. All types of stores, regular-price department stores as well as discount stores, use comparative price claims to frame price deals as attractive [Marketing Science 4 (1985) 199]. In this paper, a quadratic model is specified for the impact of external reference price (ERP) on consumer price expectations. Based on the research on communication discrepancy and advertising claim discrepancy, which in turn draw on assimilation-contrast, attribution, and prospect theories, we hypothesize a quadratic effect of external reference prices on consumer price expectations. An interactive, computer-controlled experiment using multiple levels of ERP is used to estimate the proposed model. As hypothesized, support for an inverted U-shape relationship is found between consumers’ updated price expectations and the difference between ERP and initial price expectations. That is, as the difference between ERP and subjects’ initial price expectations increases, subjects’ updated price expectations increase to a point and then start to decrease. We find that the fit of the quadratic model specification for the effect of external reference price on price expectations is noticeably superior to that of linear, logarithmic, square root, and S-shaped specifications. Finally, we provide implications of our results for both retail managers and for regulatory authorities alike.

农业创业情境下商业模式设计的影响机制研究——基于模糊集定性比较分析

农业创业者如何通过整合与管理资源与能力，设计新颖型商业模式创造更多价值，是实现乡村振兴战略的关键措施。文章基于资源编排、商业模式理论，以央视《致富经》栏目40个案例为样本，运用模糊集定性比较分析（fsQCA）方法，剖析资源编排、机会能力、创业学习所构成的前因变量组态对农业创业活动中商业模式设计的影响机制。研究发现，资源编排在农业创业活动中发挥不可或缺的关键作用；相较于资源结构化和资源捆绑，资源利用在新颖型商业模式设计中的作用更为突出；机会能力须与资源编排共同作用，方可实现新颖型商业模式设计；在资源编排作用缺乏时，创业学习的发挥有助于新颖型商业模式设计的形成。研究成果诠释了农业创业情境下资源编排、机会能力与创业学习对商业模式设计的影响机制，为开展农业创业活动提供指导。     

Comparative Urbanism and the ‘Asian City': Implications for Research and Theory

While voices in the comparative urbanism literature call for researchers to approach comparison with more experimental and critical methodologies, there remains no consensus on how to design and realize these studies. This essay examines the implications of comparative urbanism for researching the ‘Asian City'. Given the critique of existing modes of comparison embedded in recent calls for a new comparative urbanism, researchers are faced with a number of pressing questions: How do we approach this ‘regional' topic in a way that both resists categorizing the ‘Asian City' as an exotic ‘other', elevating it onto a mythical pedestal, yet appreciates its differences, localisms and unique ‘cosmopolitan vernacular' (Clifford, 1997; Werbner and Modood, 1997)? This essay thus highlights the multiple challenges of applying the comparative lens to the ‘Asian City', arguing that broader conceptualizations of the ‘Asian City' help to address the dangers in isolating Asian research into its own canon of parochial urban theory and offering a greater diversity of possibilities for justifying case selection in comparative approaches. In doing so, we hope that this essay responds to the comparative turn by illuminating to some extent its inherent complexity and methodological challenges.     

黑龙江省大豆比较优势分析

黑龙江省是世界大豆的原产地,中国大豆的主产区。加入世界贸易组织后,在国外转基因大豆的冲击和跨国粮商的操控下,大豆已经由黑龙江省的比较优势产品转化为比较劣势产品。要振兴大豆产业,必需采取多项措施提升非转基因大豆和大豆加工企业的竞争力。     

Competitive and Comparative Advantage: Towards a Unified Theory of International Trade

The field of international business/economics is largely dualistic in nature. On one hand is the economics literature which has, for two centuries, focused on the notion of comparative advantage (technology, factor proportions) while on the other is the business literature which has recently developed the concept of competitive advantage. This paper presents a reconciliation of the two based on global value chain/supply chain analysis and the concept of vertical comparative advantage. It is shown that the theory of competitive advantage's epistemological comparative advantage lies with its ‘how to’ approach to developing an advantage, while the theory of comparative advantage's epistemological comparative advantage lies with its account of ‘what is’ and that both are complementary. However, it is also argued that the failure to recognize this complementarity as well as the shortcomings of each have prevented and continue to prevent the emergence of an integrated, empirically-consistent theory of international trade – in short, prevented us from taking advantage of the gains from epistemological trade.     

Distributional consequences of political representation

We investigate, both theoretically and empirically, the effect of the geographic concentration of representatives on the geographic distribution of fiscal transfers. Our theoretical model predicts that more representatives residing in a geographic area leads to higher government funds to that area. Our empirical analysis uses the fact that in Germany, due to Germany׳s electoral rules in state elections, the number of representatives varies across electoral districts. Controlling for various socio-economic, demographic, and political variables and using a variety of estimation methods, we find that districts with a greater number of representatives receive more government funds.     

基于广义价值论的内生增长理论初探

增长理论是经济学的重要部分，关系到每一个人的福利和一个国家的地位。文章运用广义价值论研究经济增长问题，以分工为切入点，把分工产生的新增利益和该利益的公平分配统一起来，论述了递增性假设之外另一条增长的可能路径。主要结论如下：（1）基于比较优势的分工交换可以持续地产生比较利益即超过自给自足收益的净收益，这一收益不依赖于技术的递增或递减变化，具有普遍持久稳定性；（2）由分工交换产生的净收益构成原始积累的重要来源，既促进了生产规模和分工范围的扩大，又支持了研发和技术进步；（3）劳动生产力任何提高的效应都通过分工交换产生的比较利益加以放大，在一个分工交换系统中，行为主体提高比较优势产品和比较劣势产品的生产力分别具有正的和负的外部性；（4）基于广义价值论的内生经济增长体现了效率与公平的统一，一个好的制度是能够保证在交易中各方的比较利益率相等，掠夺性制度不仅直接损害经济增长，也不具备长期可持续性。     

Quota prices as indicators of comparative advantage in supply‐managed industries

The Canadian dairy, egg, broiler, and turkey industries operate under supply management, a policy regime that sets product prices and allocates production among provinces and ultimately among farms through quotas. The Canadian Farm Products Agencies Act requires that comparative advantage be used to guide the allocation of new quota when increases in consumer demand necessitate increased production. This requirement, however, has not been met in practice. We develop a proposal by Meilke to use quota prices as measures of comparative advantage. We evaluate the quota price approach and other proposed methods, from a Hayekian and Coasean market process perspective. We conclude that quota prices offer an economically justifiable indicator of provincial comparative advantage. We develop an individual‐level general equilibrium model of quota exchange to illustrate the informational content of quota prices as indicators of comparative advantage. We also discuss potential practical challenges of using quota prices as indicators of comparative advantage.
