This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students. 相似文献

In this paper, we consider a continuum economy with a finite number of types of agent, and several private and public goods. The main result of the paper is that the graph of the equal-treatment Lindahl equilibria mapping is the unique abstract stable set with respect to the dominance relation in economies with crowding effects introduced by Vasil'ev et al. in 1995. The external stability of this mapping implies that, for any equal-treatment allocation x in , that is not a Lindahl equilibrium, there exists a subeconomy of such that one of its equal-treatment Lindahl allocations blocks x. This result is a counterpart of the theorem of Mas-Colell for Aumann's atomless market with private goods. 相似文献

This paper investigates efficiency and equitability issues given a cost sharing method in an economy with a public commodity. We study the concept of a -cost share equilibrium and examine the set of all equilibrium allocations. Finally, we devise a mechanism to implement -cost share equilibria as strong equilibria of an associated non-cooperative game.This paper was written while Shlomo Weber was visiting the University of Bonn.

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important
paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line,
we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly
top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes
requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with
statistical rank based tests.

Economic models typically allow for “free disposal” or “reversibility” of information, which implies non-negative value. Building
on previous research on the “curse of knowledge” we explore situations where this might not be so. In three experiments, we
document situations in which participants place positive value on information in attempting to predict the performance of
uninformed others, even when acquiring that information diminishes their earnings. In the first experiment, a majority of
participants choose to hire informed—rather than uninformed—agents, leading to lower earnings. In the second experiment, a
significant number of participants pay for information—the solution to a puzzle—that hurts their ability to predict how many
others will solve the puzzle. In the third experiment, we find that the effect is reduced with experience and feedback on
the actual performance to be predicted. We discuss implications of our results for the role of information and informed decision
making in economic situations.
