Summary. A body of empirical work documents that most people believe they are above average in a variety of skills and abilities. This paper argues that such evidence does not necessarily imply that people process information in an irrational way. I build a model in which people can learn about their abilities at a cost of foregone production. Individuals in this model keep testing their abilities until their self-assessments become favorable enough, at which point they stop. This way, a disproportionately large share of the population ends up with a high opinion about their abilities.Received: 22 August 2001, Revised: 20 March 2003, JEL Classification Numbers:

In this article different spatial statistics techniques to analyze the behavior of used dwelling market prices are compared. We fit two lattice models: simultaneous and conditional autoregressive, a geostatistical model, the so-called universal kriging and finally, a linear mixed-effect model. Different spatial neighborhood structures are considered, as well as different spatial weight matrices and covariance models. The results are illustrated through a real data set of 293 properties from Pamplona, Spain. 相似文献

From value chain to value constellation: designing interactive strategy 总被引:54,自引:0,他引:54
In today's fast-changing competitive environment, strategy is no longer a matter of positioning a fixed set of activities along that old industrial model, the value chain. Successful companies increasingly do not just add value, they reinvent it. The key strategic task is to reconfigure roles and relationships among a constellation of actors--suppliers, partners, customers--in order to mobilize the creation of value by new combinations of players. What is so different about this new logic of value? It breaks down the distinction between products and services and combines them into activity-based "offerings" from which customers can create value for themselves. But as potential offerings grow more complex, so do the relationships necessary to create them. As a result, a company's strategic task becomes the ongoing reconfiguration and integration of its competencies and customers. The authors provide three illustrations of these new rules of strategy. IKEA has blossomed into the world's largest retailer of home furnishings by redefining the relationships and organizational practices of the furniture business. Danish pharmacies and their national association have used the opportunity of health care reform to reconfigure their relationships with customers, doctors, hospitals, drug manufacturers, and with Danish and international health organizations to enlarge their role, competencies, and profits. French public-service concessionaires have mastered the art of conducting a creative dialogue between their customers--local governments in France and around the world--and a perpetually expanding set of infrastructure competencies. 相似文献

Conclusion The privatisation and liberalisation steps referred to are an expression of the endeavour to accompany stabilisation efforts as quickly as feasible with the institutional and systemic changes as well as with policies for restructuring, to change the behaviour patterns of economics agents. Until this change takes place, the more effective the restrictive policies are in the financial sphere, the higher the costs incurred in the real sphere will tend to be.The achievement of the desirable trade-offs between the conflicting aims of the macroeconomic development is thus linked with the degree of success in the changes of behaviour of economic agents. The macroeconomic stabilisation will therefore in the longer run depend on the extent to which the regime actually changes, on the positive destabilisation of economic agents and on the progress in their restructuring.In Czechoslovakia there does not therefore seem to be as clear-cut a distinction, as in other reforming countries, between the phases of stabilisation policies, institutional and systemic changes and those of the restructuring policies.The measures to transform the Czechoslovak economy and the implementation of these measures represent an attempt to proceed on a wider front, to take coordinated steps in all the relevant spheres, implying a greater degree of simultaneity. This is a reflection of the strategy chosen which aims at a qualitative change to be accomplished rapidly, taking into account the fact that the individual steps in the various spheres of the transition process are closely interconnected. The approach followed could thus be considered a strategy to introduce groups of complementary policy measures, that is to say, to make several reform packages and to implement them sequentially. 相似文献

Efficiency and Equity in Natural Resources Pricing: A Proposal for Urban Water Distribution Service 总被引:2,自引:1,他引:2
This paper focuses on the design of optimal prices for urban water distribution service. In this context, pricing should be aimed at achieving efficiency, equity, financial aspects, and/or public acceptability and transparency. The proposed tariffs are based on the theoretical frameworks suggested by Ramsey (1927) and Feldstein (1972). As a prior step, estimations of urban water demands and water costs are carried out for the Spanish municipality of Seville. Finally, an empirical comparison, in welfare terms, is conducted between the proposed tariffs and those applicable in the year 2000. 相似文献

This paper determines the precise connection between the curvature properties of an objective function and the ray-curvature properties of its dual. When the objective function is interpreted as a Bernoulli or cardinal utility function, our results characterize the relationship between an agent’s attitude towards income risks and her attitude towards risks in the underlying consumption space. We obtain these results by developing and applying a number of representation theorems for concave functions.The work of Juan E.

In this paper, we empirically investigate the determinants of the governance form of strategic alliances. We use a database
with 1,344 worldwide alliances in several industrial sectors. In contrast with previous empirical studies, we find that alliances
undertaking R&D activities are more likely to use loose forms of organization (contractual agreements) than more hierarchical
ones (joint ventures), and this result is even stronger when the alliance takes place in technologically sophisticated sectors.
Moreover, we show that alliances between rival firms tend also to be organized with forms closer to arm’s length transactions.
When the scope of an alliance is multidimensional or the alliance is an international one, however, firms prefer more hierarchical
organizations such as joint ventures.

This work aims to explain firms’ decisions to adopt Internet-based e-commerce, and the extent to which the adopters subsequently
implement e-commerce to commercialize their products and services. We examine various types of factors previously considered
by the literature (competitive environment, organizational characteristics, strategic orientation, innovative capacity, managers’
characteristics, IT equipment possessed and the use made of it). The analytical model developed here on the basis of a sample
of 2,038 firms suggests that the factors influencing the adoption decision are different from those that eventually influence
the results of firms’ commercial operations on the Internet. Likewise, we discuss the contribution of each type of determinant
and the implications.

Research policy and endogenous growth 总被引:4,自引:0,他引:4
This paper studies the effects of different types of research policy on economic growth. We find that while subsidies to private research, public funding of private projects, and basic research performed at public institutions have unambiguously positive effects on growth, performing applied research at public institutions could have negative growth effects. This is due to the large crowding out of private research caused by public R&D when it competes with private firms in the patent race.JEL Classification:
