We compare three market structures for monetary economies: bargaining (search equilibrium); price taking (competitive equilibrium); and price posting (competitive search equilibrium). We also extend work on the microfoundations of money by allowing a general matching technology and entry. We study how equilibrium and the effects of policy depend on market structure. Under bargaining, trade and entry are both inefficient, and inflation implies first‐order welfare losses. Under price taking, the Friedman rule solves the first inefficiency but not the second, and inflation may actually improve welfare. Under posting, the Friedman rule yields the first best, and inflation implies second‐order welfare losses.  相似文献

Continuums of Care (CoCs) are the primary coordinating bodies for homeless services in the United States. However, the complexities involved in delivering homeless services across interagency networks challenges coordination and system improvement. CoC governance, planning, and service provision have received little attention in academic literature, and thus, Continuums attempt to manage complex systems with little guidance. This evaluation applied community-based system dynamics with homeless consumers and service providers to (1) identify capability traps that impede services delivery and to (2) engage stakeholders in a structured system improvement process. Results revealed organizational structures for governance and planning that inhibit system outcomes. Insights led to policy and practice recommendations for the homeless system.  相似文献

This paper calls for a recognition of existential issues in family therapy. It begins by noting the importance of "big questions" to families, reviews the roots of existential philosophy and existential therapy, offers an example of the usefulness of connecting existential thought to the family field by discussing differentiation/ fusion from an existential perspective, and offers guidelines for clinical application.  相似文献

This paper summarizes a detailed plan for evaluation of the residential energy conservation programs offered by the Bonneville Power Administration (BPA). The major purpose of the evaluation is to determine the energy savings attributable to the programs and to identify differences between program participants and nonparticipants. The focus of this paper is on the sampling issues associated with reliable estimates of energy savings. The methodology attempts to correct for the self-selection bias likely to occur in conservation program evaluation by using intentional nonrandom sampling. In addition, the paper suggests a variety of analytical approaches to analyzing the data with respect to energy savings.The proposed design, using four different groups to estimate program effects, is a comprehensive endeavor. This is appropriate for BPA because of the substantial investment it is making in conservation. However, the design is flexible and allows for use offewer groups to reduce evaluation costs.  相似文献

This article is one physician's account of his experiences in managing a large multispecialty group practice. While he was able to accomplish much in his tenure during the latter half of the 1980s, it was, on balance, a negative experience. He describes both the high and the low points of the period and assesses how both contributed to his eventual downfall. While personal, the account has important implications for others involved in the rapidly changing, personally rewarding, and eminently challenging health car system in which physician executives work.  相似文献

The term “intercurrent events” has recently been used to describe events in clinical trials that may complicate the definition and calculation of the treatment effect estimand. This paper focuses on the use of an attributable estimand to address intercurrent events. Those events that are considered to be adversely related to randomized treatment (eg, discontinuation due to adverse events or lack of efficacy) are considered attributable and handled with a composite estimand strategy, while a hypothetical estimand strategy is used for intercurrent events not considered to be related to randomized treatment (eg, unrelated adverse events). We explore several options for how to implement this approach and compare them to hypothetical “efficacy” and treatment policy estimand strategies through a series of simulation studies whose design is inspired by recent trials in chronic obstructive pulmonary disease (COPD), and we illustrate through an analysis of a recently completed COPD trial.  相似文献
