Policymakers are stuck in time. Political short-termism, policy myopia, policy short-sightedness, and similar words have been coined to emphasize the present-centric policy thinking. Politics tends to produce short time horizons, and as a result, policymakers often fail to use present opportunities to mitigate future harms. Focusing on fiscal and monetary strategic interactions, given different separate decision makers, our paper aims to explore the effects of policymakers’ time horizons on debt stabilization. To formalize our ideas, we use the novel concept of Nonlinear-model-predictive-control Feedback Nash Equilibrium (NFNE) and find that present-centric policy thinking and decision horizons matters under several dimensions.  相似文献

Governments at all levels buy mission‐critical goods and services whose attributes and performance requirements are hard to define and produce. Many governments—and the public managers who lead them—lack experience and knowledge about how to contract for complex products. The contract management counsel provided to public managers is thin. Missing is a conceptual managerial framework to guide purchasing the complex products that are often so critical to public organizations' core missions. Drawing on perspectives from across the social sciences, the framework presented in this article provides guidance on how managers can harness the upsides of complex contracting while avoiding its pitfalls. The framework helps identify conditions that increase the likelihood of positive outcomes for the purchasing government and the vendor—the win‐win. To illustrate the framework, the article provides examples of successful and failed acquisitions for complex products such as transportation projects, social service systems, and information technology systems.  相似文献

We show that a transfer received by a minority of the population may be sustained by majority voting, however small the minority targeted may be, when the attribution of the transfer is seen as stochastic by voters. We build a simple model wherein voters differ in income and vote over a proportional tax whose proceeds are distributed lump-sum, and each voter has a probability of receiving the transfer that depends on his income. In progressive steps, we present intuitively appealing sufficient conditions on this probability function for the social program to be supported by majority voting. We also develop intuitive conditions for the emergence of the “paradox of redistribution”, whereby more focused targeting reduces the size of the transfer program chosen by the majority. We finally apply our framework to the French social housing program and obtain that our model is consistent with a majority of French voters supporting a positive size for that program.  相似文献

Replication studies relate to the scientific principle of replicability and serve the significant purpose of providing supporting (or contradicting) evidence regarding the existence of a phenomenon. However, replication has never been an integral part of public administration and management research. Recently, scholars have called for more replication, but academic reflections on when replication adds substantive value to public administration and management research are needed. This article presents the RNICE conceptual model, for assessing when and how a replication study contributes knowledge about a social phenomenon and advances knowledge in the public administration and management literatures. The RNICE model provides a vehicle for researchers who seek to evaluate or demonstrate the value of a replication study systematically. The practical application of the model is illustrated using two published replication studies.  相似文献

The article scrutinizes the emergence and expansion of EU-related professions and forms of occupation from a field-analytical perspective. Starting from the observation that the EU is not just an influential political actor, but also an expanding area of work, expert involvement and job specialization the paper discusses various forms, dimensions and loci of the ongoing “professionalization” of Europe. It is shown that the expansion of EU-related professional activities is not just a phenomenon of Brussels and the “Eurocracy”, but has expanded into the member states and various areas of occupational activity and expertise. The EU professionalization is conceptualized as a transnational field of specialization and professionalization which produces own principles, forms of knowledge and resources which are used and reproduced by experts and specialists. The field perspective allows identifying common principles, but also the variance and transnational dimension of EU affairs.  相似文献

This article addresses the question of whether the economic crisis provides a politically opportune time to drastically curtail public healthcare in South Europe or whether, instead, there are signs of longer-term reform strategies for potentially balancing fiscal targets with the quest for enhanced value and health outcomes, when eventually growth resumes. After a brief examination of the profile of healthcare systems in Greece, Italy, Portugal and Spain prior to the crisis, we comparatively assess the mix of retrenchment, restructuring and recalibration strategies. The effects of the austerity-driven reforms on current (and expected) health outcomes are also briefly analysed. We conclude with reflections on the future of public healthcare in South Europe.  相似文献

Since the 1980s, regulated markets and New Public Management have been introduced in the public sector across the world. How they have affected existing governance mechanisms such as self‐regulation and state regulation has remained largely unexplored, however. This article examines the origins and consequences of institutional layering in governing healthcare quality. Dutch health care, where a market‐based system has been introduced, is used as a case study. The results show that this market‐based system did not replace but modified existing institutional arrangements. As a result, hospitals have to deal with the fragmentation of quality demands. Using the concept of institutional layering, this study shows how different arrangements interact. As a consequence, the introduction of a certain policy reform will work out differently in different countries and policy sectors. Our ‘archaeological’ study in this layering can be seen as an example of how such incremental change can be studied in detail.  相似文献

The recent conflict in the Sahel area is another case where the nexus of terrorism and organized crime causes challenges to the international community. Comparing the situation with that of the Andean region brings forth the challenges faced when dealing with this type of conflict: the states’ weak presence in the remote regions, the insurgents’ ability to offer income and “security” to the people, immediate threat to international investments, unresolved political/regional issues, the marriage of convenience of insurgents/terrorists and organized crime, internal divisions of the insurgent groups and also ideologies surviving or suffering after the elimination of their leaders.  相似文献
