Since public networks became widespread, doubts have arisen over how to make them succeed. Scholars have traditionally addressed the issue in different ways, thus variously shedding light on the network structure, mechanisms, or managers as predictors of the network performance. The aim of our article is to explore the possibility of an interaction effect between the abovementioned factors. Our results show that there may be a relationship between network structure, mechanisms, and managers that jointly affects network performance. Therefore, important suggestions can be made about how to manage public networks successfully: (1) ensure that your network mechanisms and managerial abilities are coherent with the structure of your network; and (2) if you are in a well-established and integrated network, allow yourself some flexibility. Data were collected through a multiple case study that focused on collaboration for joint provision of home care services in Switzerland.  相似文献

The aim of this paper is to assess whether and to what extent public sector hospital reports in New Zealand disclose information which best support the public interest. We analyse the content of the annual reports of Crown Health Enterprises (CHEs) for 1994, 1995 and 1996. It is concluded that the developments in public sector accounting, with respect to the public interest, have not permeated these reports to any significant extent. The following changes would improve these reportings: Reports providing costs relative to non-financial accomplishments; removing the traditional 'revenue' disclosure; disclosing non-financial as well as financial resources and obligations; providing further disaggregation in the reports; disclosing budgetary information and valuing assets alternatively. Implications of the lens used for the analysis are also considered.  相似文献

Aspiration levels are a relevant aspect of decision making. We develop a model that includes the overall probabilities of success and failure relative to the aspiration level into an expected utility representation. This turns out to be equivalent to expected utility with a discontinuous utility function. We give a behavioral foundation to the proposed model and provide conditions to determine the relative weights of the overall probabilities of success and failure. An aspiration level reinforces loss aversion, can account for simultaneous risk‐averse and risk‐seeking behavior, and can explain choices violating the mean‐variance approach.  相似文献

In 2005 the Netherlands drafted a new innovation policy, consisting of a basic package for all entrepreneurs and a programme-based package aimed at supporting the Dutch industry in achieving global excellence in a limited number of (business) areas. The programme-based package is characterized by an integral approach, resulting in user-driven public-private innovation programmes. In the new approach, industrial foresight processes are integrated with actual policy implementation. In this paper, we include the lessons learned during the process that led to the first innovation programmes. Also, some unresolved issues in the new approach are discussed.  相似文献

Measures of national product can be misleading because there is nonmarket production. There are also distortions due to transactional activities, which are expenditures to support transactions, not actual output consumed. For 1950–89, this study recalculates output for the United States, adjusting for transactional activities and nonmarket production. Due to relatively rapid growth in transactional activities, GNP overstates output growth in the 1950s; because there was slow expansion of transactional activities in the early 1970s, GNP understates actual output. Since 1974, increases in transactional activities and shifts to market production lead GNP to exaggerate improvement of "actual" output per capita.  相似文献

Abstract

The sustained reduction in mortality rates and its systematic underestimation has been attracting the significant interest of researchers in recent times because of its potential impact on population size and structure, social security systems, and (from an actuarial perspective) the life insurance and pensions industry worldwide. Despite the number of papers published in recent years, a comprehensive review has not yet been developed.

This paper attempts to be the starting point for that review, highlighting the importance of recently published research—most of the references cited span the last 10 years—and covering the main methodologies that have been applied to the projection of mortality rates in the United Kingdom and the United States. A comparative review of techniques used in official population projections, actuarial applications, and the most influential scientific approaches is provided. In the course of the review an attempt is made to identify common themes and similarities in methods and results.

In both official projections and actuarial applications there is some evidence of systematic overestimation of mortality rates. Models developed by academic researchers seem to reveal a trade-off between the plausibility of the projected age pattern and the ease of measuring the uncertainty involved. The Lee-Carter model is one approach that appears to solve this apparent dilemma.

There is a broad consensus across the resulting projections: (1) an approximately log-linear relationship between mortality rates and time, (2) decreasing improvements according to age, and (3) an increasing trend in the relative rate of mortality change over age. In addition, evidence suggests that excessive reliance on expert opinion—present to some extent in all methods—has led to systematic underestimation of mortality improvements.  相似文献
