Strongly stable networks

We analyze the formation of networks among individuals. In particular, we examine the existence of networks that are stable against changes in links by any coalition of individuals. We show that to investigate the existence of such strongly stable networks one can restrict focus on a component-wise egalitarian allocation of value. We show that when such strongly stable networks exist they coincide with the set of efficient networks (those maximizing the total productive value). We show that the existence of strongly stable networks is equivalent to core existence in a derived cooperative game and use that result to characterize the class of value functions for which there exist strongly stable networks via a “top convexity” condition on the value function on networks. We also consider a variation on strong stability where players can make side payments, and examine situations where value functions may be non-anonymous—depending on player labels.     

LIQUIDITY,MONEY CREATION AND DESTRUCTION,AND THE RETURNS TO BANKING*

We build on our earlier model of money in which bank liabilities circulate as a medium of exchange. We investigate optimal bank behavior and the resulting provision of liquidity under a range of central bank regulations. In our model, banks issue inside money under fractional reserves, facing the possibility of excess redemptions. Banks consider the float resulting from money creation and make reserve‐management decisions that affect aggregate liquidity conditions. Numerical examples demonstrate positive bank failure rates when returns to banking are low. Central bank interventions may improve banks' returns and welfare through a reduction in bank failure.     

A Common Base Answer to the Question “Which Country Is Most Redistributive?”*

We believe that what most authors have in mind when referring to the “most redistributive country” is a tax and transfer schedule that is most redistributive across all pre-tax and transfer income distributions. In order to measure each country's tax and transfer redistribution according to the same baseline, we suggest using the transplant-and-compare method of Dardanoni and Lambert (2002, Journal of Public Economics 86, 99–122) to establish a common base. The redistributive effects of countries’ tax and transfer schedules are illustrated by employing microdata on eight countries from the Luxembourg Income Study (LIS). Of these eight countries, Finland is found to be the most redistributive country, according to the common base method.     

EVIDENCE ON THE RELATIONSHIP BETWEEN ECONOMICS AND CRITICAL THINKING SKILLS

This research provides empirical support for the hypothesis that learning economics increases a student's critical thinking skills. Using the short form of the Watson-Glaser Critical Thinking Appraisal (WGCTA-S) as our measure of critical thinking skills, we find that students who gain a high level of economic understanding in their introductory economics class, as measured by the Test of Understanding College Economics (TUCE), have statistically significant gains in their WGCTA-S scores. Students who spend more time taking classes and are more fully engaged in the university experience also have greater gains in critical thinking. These results lend support to the idea that introductory economics courses can work in concert with other university level courses, especially within the context of a full-time curriculum, to enhance critical thinking skills.

Subgame perfection in ultimatum bargaining trees

In typical experiments on ultimatum bargaining, the game is described verbally and the majority of subjects deviate from subgame-perfect behavior. Proposers typically offer significantly more than the minimum possible and Responders reject “unfair” offers. In this work, we show that when the ultimatum bargaining game is presented as an abstract game tree, the vast majority of behavior is consistent with individualistic preferences and subgame-perfection. This finding raises doubts about theories that ignore the potential influence of social context and experiments that do not control for social context.     

Efficient propagation of shocks and the optimal return on money

We study optimal allocations in an environment in which money is essential due to lack of commitment and anonymity of individuals. Because the economy features aggregate preference shocks, we apply a notion of implementability that allows for allocations with non-trivial business-cycle dynamics for the propagation of shocks. We show that history dependence is predicted by the theory of second best and becomes necessary for optimality when the degree of patience is neither too low nor too high. Our analysis concludes with a discussion of whether there is a role for the propagation of shocks in alternative economic environments.     

Technological leadership and sectorial employment growth: A spatial econometric analysis for U.S. counties

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.     

Factors influencing organizational participation in the Clinical Nurse Leader project

When the American Association of Colleges of Nursing introduced the Clinical Nurse Leader"s (CNL) pilot project in 2004, it was the first time in more than 40 years that an attempt was made to introduce a new role to the profession. This new role was designed to address many challenges related to patient care in the current health care delivery system including a need for more effective clinical problem solving, better coordination at the point of care, stronger interdisciplinary relationships, and more rapid implementation of evidenced-based practice findings at the patient-provider interface. Critics from both academic and practice settings have questioned the need and wisdom of introducing a new role to the profession at this time. The factors that led some nursing leaders in early stages of this project to be proactive and involve their organizations as early adopters of the CNL role were examined in this study. Five major factors were identified from the research to form a framework designed to explain organizational participation: organizational needs, a desire to improve patient care, an opportunity to redesign care delivery, the promotion of the professional development of nursing staff, and the potential to enhance physician-nurse relationships. The ability of academic and service partners to forge the types of relationships and promote best practices as is occurring in the CNL project may be a critical success factor in confronting the current and impending nursing shortage.
