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.     

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.     

Collaboration,information, and preservation: The role of expertise in farmland preservation task forces

Collaboration between agencies, private groups, and citizens in the field of natural resource management is generally seen as a productive strategy in challenging management situations. Collaborative management is particularly appealing in efforts like farmland preservation, which depend for their success on local initiative and support. However, such partnerships may create new dilemmas about the appropriate use of information in management. This paper analyzes the use of information by 15 county-wide Farmland Preservation task forces in the state of Ohio, U.S.A.
