Where Should the Elderly Live and Who Should Pay for Their Care?*

We consider a model with a population consisting of earners and retired persons; elderly care is publicly provided. There is one big city, where congestion effects and agglomeration forces are at work, and a number of small villages. We show how the externalities related to population mobility lead to an inefficient spatial distribution of earners and retirees, and we characterize the second‐best solution. Decentralization of this solution in a fiscal federalism structure requires the use of taxes and subsidies proportional to the number of earners and retired persons living in the city and the villages.     

Market Orientation,Competitive Strategy and Firm Performance

Abstract

In this paper, we investigate the mediating effects of a firm's competitive strategy in the market orientation-performance relationship. Based on a sample of 371 manufacturing firms in China, evidence was found that the three dimensions of market orientation exert different effects on competitive strategy and performance. Among them, customer orientation has the strongest association with competitive strategy and market performance. This lends credence to a componentwise approach on the study of the relationship between market orientation and performance. The results of structural equation analyses indicate that the mediating effect of competitive strategy is mainly revealed in innovation strategy, the most vital factor in creating superior value for the company in the emerging market. Limitations of this study and implications for future studies are discussed.

COOPERATION: THE POWER OF A SINGLE WORD? SOME EXPERIMENTAL EVIDENCE ON WORDING AND GENDER EFFECTS IN A GAME OF CHICKEN

Framing has been widely shown to affect decision making. In this paper, we investigate experimentally whether, and to what extent, cooperative behaviour in a Game of Chicken may be impacted by a very basic change in the labelling of the strategies. Our within‐subject experimental design involves two treatments. The only difference between them is that we introduce either a socially‐oriented wording (I cooperate/I do not cooperate) or colours (red/blue) to designate strategies. The level of cooperation appears to be higher in the socially‐oriented context, but only when uncertainty as regards the type of the partner is manipulated, and especially among females.     

A reference-dependent representation with subjective tastes

Experimental and empirical evidence documents instances where the presence of an inferior option in a menu increases the attractiveness of the better options from that menu and thus distorts the normative ranking across menus. We analyze the case when in addition to this so called context-effects bias there is also a concern for flexibility, in the spirit of the literature initiated by Kreps (1979) and Dekel et al. (2001). Since the context-effects bias and the desire for flexibility both increase the inclination of a decision maker to choose larger menus, our analysis allows the disentangling of the effect of the behavioral bias from the effect of the rational desire from flexibility. We find a weak condition on the set of ex post preferences under which the two effects are identifiable. We show that our representation is essentially unique. From a methodological viewpoint, our paper provides a novel technique of identifying probabilities on the state space of subjective uncertainty introduced by Dekel et al. (2001) when this state space is infinite. This method renders the infinite state space essentially finite with respect to a certain salient property.     

The impact of perceived security and consumer innovativeness on e-loyalty in online travel shopping

ABSTRACT

This study investigates the impacts of perceived security and consumer innovativeness on online travel shopping. A survey questionnaire was used to collect data and a total of 283 questionnaires were used for data analysis. The mechanism of perceived security and consumer innovativeness was then identified. The study results indicate that: (1) higher perceived security increases the perception of website image and trust; (2) consumers with a higher level of innovativeness tend to trust travel websites; (3) website image has a mediating effect between perceived security and trust; and (4) trust has a mediating effect between website image and e-loyalty.     

农村集体资产管理的政府干预探析

政府的适时介入、适度干预是强化农村集体资产管理的必然之需。但是，政府对农村集体资产管理的干预是一柄“双刃剑”：一方面，这种干预起到了提高农村财务人员素质、规范农村财务管理以及从源头治腐等积极效应；另一方面，这种干预也引发了侵害集体财产、增加基层政府财政压力等负面效应。当前，亟须对农村集体资产管理政府干预的路径进行优化：一是要明确农村集体资产管理政府干预的基本原则，二是要解决好农村集体资产管理政府干预的四个关键性问题。
