The recent globalization of world economies has led the retail markets of developed countries towards increasing levels of integration and strategic interdependence. A non negligible share of retail and food markets is currently served by co‐operative societies. Consistently with this trend, the consumer cooperatives have recently experienced increasing levels of integration. The main aim of this paper is to study the welfare effects of coordination among consumer cooperatives competing in quantities in a mixed oligopoly against profit‐maximizing firms. We show that, in absence of agency problems, under increasing or constant returns to scale a higher output coordination of the consumer cooperatives does not affect the total welfare as long as a nonnegative profit constraint holds in these firms. On the other hand, under decreasing returns to scale, the consumer cooperatives contribute more to social welfare when acting on behalf of all consumers. This is because, by coordinating consumers’ preferences, these firms can reduce their market output, thus helping the market to come closer to the first best. All together these results seem to provide an argument in favour of the recent process of integration involving consumer cooperatives in many developed countries.  相似文献

Sustainability Northwest (SNW) is a fictional not‐for‐profit organization (NPO) that seeks to develop thought leaders for a sustainable future. This instructional case allows professors to assign students with up to six different roles, including SNW's chair of the board, executive director, volunteer treasurer, and the external auditor. Unique learning objectives include (i) the application of the CPA Canada Handbook, Accounting—Part III to prepare an NPO's financial statements using fund accounting, (ii) the development of recommendations to improve an NPO's board of directors, (iii) the analysis of system flow documents to identify control weaknesses, and (iv) the preparation of an audit planning memo. Instructors can use this case in several milieus. First, professors can foster a student's ability to integrate technical knowledge by (i) assigning students all six roles in a capstone course to promote integration within an individual course or (ii) assigning multiple roles across multiple courses to promote integration across a program of studies. Second, instructors can focus on a particular technical skill by assigning specific roles. This case is ideal for senior‐level undergraduate students or graduate students.  相似文献

This paper uses data envelopment analysis to assess the operational performance of 28 Italian airports during the period of 2000 through 2006. Recent developments in bootstrapping techniques are used to correct total factor productivity estimates for bias and to assess the uncertainty surrounding such estimates. This study found that the Italian airport industry experienced a significant technological regress, with few airports achieving an increase in productivity led by improvements in efficiency. Moreover, the paper shows that the form of ownership (public majority vs. private majority) of an airport management company does not significantly affect performance. In contrast, this type of the concession agreement has positive and significant effects on airport productivity. Finally, the paper highlights the existence of a productivity gap between airports located in the North-Central part of the country and those located in the south.  相似文献

This study compares the individual, household and location characteristics of private employees, the self-employed, the unemployed and the economically inactive in Kazakhstan making use of a 1996 World Bank Living Standards Measurement Survey. The purpose is to understand whether the process of transition has determined a selection of workers exiting the state sector and entering the three relatively new 'pools' of private employees, self-employed and unemployed. An 'occupational choice' model is used to explore the determinants of sector participation. It is found that income opportunities are similar between the private and self-employment sectors, that the private sector is not necessarily the workers' first choice and that non-income determinants including local economic and labour market conditions and household related factors explain better than income the choice of the working sector. Self-employment seems to be a key sector in understanding the mechanisms of sector choice and the reallocation of labour. Unemployment appears as a choice of last resort and made by truly 'rationed' individuals.  相似文献

Summary. We focus on the following uniqueness property of expected utility preferences: Agreement of two preferences on one interior indifference class implies their equality. We show that, besides expected utility preferences under (objective) risk, this uniqueness property holds for subjective expected utility preferences in Anscombe-Aumann's (partially subjective) and Savage's (fully subjective) settings, while it does not hold for subjective expected utility preferences in settings without rich state spaces. Indeed, when it holds the uniqueness property is even stronger than described above, as it needs only agreement on binary acts. The extension of the uniqueness property to the subjective case is possible because beliefs in the mentioned settings are shown to satisfy an analogous property: If two decision makers agree on a likelihood indifference class, they must have identical beliefs.

Asymmetric Reaction Functions for the Euro Area   总被引:2,自引:0,他引:2  
This paper offers a preliminary evaluation of ECB conduct ofmonetary policy by estimating a fairly general reaction functionfor the euro area. The specification of the policy rule embodiesa number of nonlinearities which are shown to stem from asymmetricpreferences and a convex aggregate supply curve. Asymmetricpreferences allow, but do not require, policy-makers to weightdifferently positive and negative deviations of inflation andoutput from the reference values, and translate into an asymmetricreaction function. The empirical analysis on monthly euro-areaaggregated data over the last 5 years reveals that ECB monetarypolicy is effectively described by a nonlinear policy rule accordingto which output contractions have required a larger policy responsethan output expansions. Moreover, actual movements in the eurointerest rate closely resemble the simulated path that a Bundesbank-typeof behaviour would have implied.  相似文献

We argue that a trade agreement which conforms to GATT’s reciprocity rule benefits the (stronger) less trade‐dependent country at the expense of the (weaker) more trade‐dependent country. Reciprocity is so unfavorable to the weaker country that it may be worse off under reciprocity than under the Nash‐ bargaining solution, a “power‐based” approach to trade negotiations that reflects power asymmetries among trading partners. Our results question Bagwell and Staiger’s (1999 , 2000 ) view of reciprocity as a rule that “serves to mitigate the influence of power asymmetries on negotiated outcomes.”  相似文献
