Social welfare functions when preferences are convex,strictly monotonic,and continuous

The paper shows that if the class of admissible preference orderings is restricted in a manner appropriate for economic and political models, then Arrow's impossibility theorem for social welfare functions continues to be valid. Specifically if the space of alternatives is R ₊ ⁿ , n ≥ 3, where each dimension represents a different public good and if each person's preferences are restricted to be convex, continuous, and strictly monotonic, then no social welfare function exists that satisfies unanimity, independence of irrelevant alternatives, and nondictatorship.     

Institutional Change and Ethnic Parties in South America

The central question of this article is why indigenous social movements formed electorally viable political parties in Latin America in the 1990s. This development represents a new phenomenon in Latin America, where ethnic parties have been both rare and unpopular among voters. Institutional reforms in six South American countries are examined to see if the creation and success of these parties can be correlated with changes in electoral systems, political party registration requirements, or the administrative structure of the state. The study concludes that institutional change is likely to be a necessary but not sufficient condition for the emergence and electoral viability of ethnic parties.     

A Second Republic for Italy?

Radical change in the representative dimension of Italy's political system was expected to bring a transition to a 'Second Republic' in Italy. That has not happened. Nevertheless, after three consultations using the new parliamentary electoral system, studies focusing on the 'input' side of Italian politics are beginning to agree that substantial change has occurred. It is, however, too early to identify the extent of change in public administration and centre–local government relations, whilst even in parliament it is argued that consensual decision-making continued at least into the late 1990s. The impact of party system change on policy-making has thus been shown to be less direct than many expected, providing rich material for research into the relationship between institutional and policy change. Nevertheless, institutional change continues, particularly with regard to the decentralisation of government, and some studies suggest that this is the key to Italy's political transformation, rather than electoral reform or even change in the form of government. Still, the election of Italy's first right-wing majority government in 2001 may yet bring change in parliamentary practice and policy-making more generally.     

Bureaucracy,Network, or Enterprise? Comparing Models of Governance in Australia,Britain, the Netherlands,and New Zealand

Theories of democratic government traditionally have relied on a model of organization in which officials act impartially, accept clear lines of accountability and supervision, and define their day–to–day activities through rules, procedures, and confined discretion. In the past 10 years, however, a serious challenge to this ideal has been mounted by critics and reformers who favor market, network, or "mixed–economy" models. We assess the extent to which these new models have influenced the work orientations of frontline staff using three alternative service types—corporate, market, and network—to that proposed by the traditional, procedural model of public bureaucracy. Using surveys of frontline officials in four countries where the revolution in ideas has been accompanied by a revolution in methods for organizing government services, we measure the degree to which the new models are operating as service–delivery norms. A new corporate–market hybrid (called "enterprise governance") and a new network type have become significant models for the organization of frontline work in public programs.     

The performance framework: a systems approach to understanding performance management

The article presents a framework for better understanding the nature of performance in organisations involved in the provision of overseas development assistance (ODA). It uses a case study to illustrate the three main features of the framework which are: goals, performance assessment and performance management. It is asserted that a vibrant performance culture is one which links these features together to form an organisation capable of continual improvement through producing effective learning. Organisational culture determines the nature of linkages between the three sub‐systems. The article stresses how the notion of performance may extend beyond various forms of evaluation and scrutiny to being part of a sentient learning system rooted in an organisation's culture and structure. The article concludes with consideration of key issues associated with the generation of a reflexive learning organisation operating in the ODA sector. These are concerned with understanding the role and nature of systems, organisational vision, the embracing of diversity, training and accountability. Copyright © 2003 John Wiley & Sons, Ltd.     

Challenges for donor agency country‐level performance assessment: a review

This review of country‐level performance assessment in donor agencies is primarily based upon the experiences documented by bilateral donors to developing countries. The review suggests that four emerging themes can be identified in the literature on country‐level performance review: ownership, decentralisation and leadership, accountability and learning and complexity. The review considers the implementation of ‘results‐based’ approaches used by a number of international agencies and examines their relationship with ‘evidence‐based’ approaches. A key challenge, in the development of performance assessment, is bringing in a stronger evidence‐based approach into the planning and evaluation of donor country‐level programmes.
