“高端服务”供给行为的经济学分析

公共利益的实现要允许市场行为的介入,“高端服务”的供给行为恰是价格机制甄选作用的具体体现。“高端服务”存在着3个层次的效率:稀缺资源配置效率的改进、公共产品供给的技术效率和公共服务的分配效率。因此,提供“高端服务”是一种经济理性行为,并未挤占公共利益。     

Conjectural Variations, Market Power, and Optimal Trade Policy in a Vertically Related Industry

The paper introduces the conjectural variations and bargaining approaches into a vertical model wherein a foreign upstream firm supplies one input to two downstream firms that produce differentiated products for the export market. Various downstream firms’ competition modes and upstream's pricing schemes emerge as special cases of this formulation. The authors show that the optimal export policy of a downstream country depends crucially on the downstream firms’ conjectures of rivals’ responses, the upstream firm's pricing schemes, their relative bargaining powers, and the degree of product differentiation. If the upstream's pricing or bargaining power is strong (weak) and if the downstream's degree of competition is high (low), a tax (subsidy) is optimal owing to a strong (weak) vertical profit‐shifting effect and a weak (strong) horizontal effect.     

论地方政府在区域合作过程中的行为--以重庆与长江上游其他省市关系为例

区域合作在很大程度上是基于地理位置临近的需要。尽管在地理位置方面没有关系的区域之间也可以有区域合作。但更多地表现为企业行为而不是政府行为。重庆与长江上游其他区域之间有地理上的密切关联，并且具有悠久的历史，政府在推动区域合作优化方面具有不可推卸和难以替代的责任。中央政府可以对这种区域合作发挥重要作用，但是，相比之下，地方政府在其中更有积极性也更适合来扮演推动这种区域合作的主角。     

Selling Australia as ‘clean and green’*

‘Clean and green’ has been used as a marketing tool by Australian governments to promote agricultural products overseas. But how valid are these claims? Is the ‘clean and green’ image campaign effective? And should government be involved? We conclude that Australia may have had a ‘clean and green’ image in some markets, but in the future, concrete proof of environmental and quality credentials will be required to satisfy increasingly better‐informed and more demanding customers. We argue that governments cannot, and should not, continue to promote Australian products based on an undefined ‘clean and green’ image. Rather, more resources should be directed to the development, promotion and wide adoption of integrated, credible and well‐defined environmental management and quality assurance systems if Australia is to compete effectively in export markets, especially in the longer term.     

Shortage marketing: A comprehensive framework

Resource shortages have recently attracted substantial attention by marketing writers. However, articles heretofore published have utilized a piece-meal approach, and no comprehensive framework exists to guide marketing strategy in scarcity periods. This paper offers such a framework, which incorporates both causal and contextual factors that must be considered in shortage strategy development.     

The impact of firm size on dynamic incentives and investment

Recent studies conclude that small firms have higher but more variable growth rates than large firms. To explore how this empirical regularity affects moral hazard and investment, we develop an agency model with a firm size process having two features: the drift is controlled by the agent's effort and the principal's investment decision, and the volatility is proportional to the square root of size. The firm improves on production efficiency as it grows, and wages are back‐loaded when size is small but front‐loaded when it is large. Furthermore, there is underinvestment in a small firm but overinvestment in a large firm.     

Siting controversies analysis: framework and method for questioning the procedure

Siting controversies are commonplace, as well against the construction of roads, railways, nuclear waste disposals, as against windfarms. Local citizens resist against siting decisions taken by the authorities, following a dynamics often quoted as ‘Not In My Back Yard’. Yet contested for its lack of analytical value, NIMBY is still used strategically by actors to qualify citizens as irrational and egoistic. Beyond this labeling, many factors are investigated to understand the dynamics behind siting controversies. In this paper, we focus on the impact of the legal procedure structuring the implantation of windfarms in the Walloon Region (Belgium), and its translations within different decision-making processes in specific case studies. To that regard, we consider the legal procedure as a ‘public policy instrument’. It is neither neutral nor natural, and carry values and interests. It organizes interpersonal relations between actors, and is potentially catalyzer of frustrations. In addition, this legal procedure is the object of translations within different contexts, including different actors participating to specific decision-making processes. The empirical approach of this paper is based on case studies data and on the use of an innovative methodology called ‘Open Process Workshop’. This methodology consists of a structured workshop with key stakeholders, during which the legal procedure is questioned. Overall, we demonstrate that the focus on the legal procedure – and its translations within different decision-making processes – allows systemic analysis providing deep understandings of controversies and reaffirming the interlinks between ‘the social’ and ‘the technical’ in such controversies. In addition, we argue that the methodology used fosters the production of innovative knowledge, mutual understanding, and collective learning between the participants.     

Methodological Issues in Advertising Research: Current Status,Shifts, and Trends

This article presents some self-reflective considerations on the methodology applied in advertising scholarly publications, based on a review of articles in four leading journals: Journal of Advertising, Journal of Advertising Research, International Journal of Advertising, and Journal of Current Issues and Research in Advertising. This article first identifies two approaches in the positivist paradigm that exert strong impacts on the development of advertising research: the message effects research tradition in the communication field and the consumer psychology research tradition in marketing. With this background, the article next introduces several research questions to explore which methods have dominated advertising research, the role of theory building in affecting the adopted methods and the number of reported studies, differences across the journals, and the degree to which researchers integrate different methods or approaches (quantitative and qualitative) in their research. A content analysis of articles published in these four advertising journals from 2001 to 2015 helps address these research questions and reveals the current status, shifts, and trends in advertising research since the turn of this century.     

Volatility trade-offs in exchange rate target zones

The volatility trade-offs (i.e. the negative relationships between exchange rate variability and the interest rate differential) exhibited in the Krugman [Krugman, P. (1991). Target zones and exchange rate dynamics. Quarterly Journal of Economics, 106, 669–682.] model depend on the assumption of uncovered interest rate parity (UIP). However, the bands for several economies in Latin America and Eastern Europe are substantially different from those within the European Monetary System (EMS), in that their parity relationship deviates from UIP and volatility trade-offs do not exist. This paper develops a graphical exposition and uses it to show that the degree of capital mobility may serve as a plausible vehicle to explain the empirical evidence found in Krugman's regime of exchange rate target zones. Based on a Fleming-type stochastic macro model, we find that when capital mobility is relatively low, exchange rate variability exhibits a positive relationship with the interest rate differential. This result can be regarded as a possible way of resolving the conflicting outcomes between Krugman's prediction and existing empirical observations.
