New development: The unknown world of transnational organizations in Europe - challenges for accountability
Mostly unknown to the general public, a fragmented landscape of transnational organizations has been developing in Europe. These organizations work across borders, but not entirely in the EU, and they generally have some basis in European law or policies. An inventory by the authors suggests there are at least 370 transnational organizations in Europe. Transnational organizations challenge basic notions of accountability: it is often very difficult to understand what the organization is doing, to whom it is accountable or even where it is located. This is not to say that accountability is necessarily a problem but much more research and insight is definitely required. IMPACT This article aims to put the almost 400 transnational organizations as a fragmented set of partially European organizations on the agenda. By understanding them as partially European (and partially regional, local or national), the authors raise issues of accountability and transparancy of those organizations. The article will be of value to European and regional policy-makers relating to various transnational organizations but also to leaders and staff in those organizations who need to relate (and account) to their important external stakeholders. These organizations offer opportunities for continued European collaboration after Brexit
Enacting accountability under populist pressures: theorizing the relationship between anti-elite rhetoric and public accountability
While populism challenges the pluralism and technocratic expertise on which public bureaucracies are based, extant scholarship has overlooked its effects on accountability processes. In particular, it neglects the impact of anti-elite rhetoric, characterized by what can be regarded as “emotionalized blame attribution,” on the thinking and behavior of accountability actors. Responding to this gap, this article examines the impact of this distinctive form of populist rhetoric on accountability relationships within the bureaucratic state. It identifies three “stages” whereby these populist pressures challenge accountability relationships, threaten the reputation of accountability actors, and result in alternative accountability practices. In doing so, the article provides a roadmap for assessing the impact of anti-elite rhetoric on accountability actions
New development: Breaking out or hanging on? Internal audit in government
Public audit is in transition. On the one hand, professional organizations claim it is time ‘to break out’ and develop new roles for auditors that ‘add more value’. On the other hand, critics are concerned about public sector accountability deficits necessitating more control and urging auditors to hold on to their traditional role. This article discusses tensions and relevance between these positions and their implications for auditing in government. The article will help policy-makers in their strategic decision-making on the role and focus of internal audit in government
Simple nudges that are not so easy
In this paper, we critically review three assumptions that govern the debate on the legitimacy of nudging interventions as a policy instrument: (1) nudges may violate autonomous decision-making; (2) nudges lend themselves to easy implementation in public policy; and (3) nudges are a simple and effective mean for steering individual choice in the right direction. Our analysis reveals that none of these assumptions are supported by recent studies entailing unique insights into nudging from three disciplinary outlooks: ethics, public administration and psychology. We find that nudges are less of a threat to autonomous choice than critics sometimes claim, making them ethically more legitimate than often assumed. Nonetheless, because their effectiveness is critically dependent on boundary conditions, their implementation is far from easy. The findings of this analysis thus suggest new opportunities for identifying when and for whom nudge interventions are preferable to more conventional public policy arrangements
Rising to Ostrom’s challenge:An invitation to walk on the bright side of public governance and public service
In this programmatic essay, we argue that public governance scholarship would benefit from developing a self-conscious and cohesive strand of "positive" scholarship, akin to social science subfields like positive psychology, positive organizational studies, and positive evaluation. We call for a program of research devoted to uncovering the factors and mechanisms that enable high performing public policies and public service delivery mechanisms; procedurally and distributively fair processes of tackling societal conflicts; and robust and resilient ways of coping with threats and risks. The core question driving positive public administration scholarship should be: Why is it that particular public policies, programs, organizations, networks, or partnerships manage do much better than others to produce widely valued societal outcomes, and how might knowledge of this be used to advance institutional learning from positives
Between mediatisation and politicisation: The changing role and position of Whitehall press officers in the age of political spin
Despite widespread critiques of ‘political spin’, the way governments engage with the mass media has attracted relatively little empirical attention. There is a small but growing body of research into bureaucracies’ responses to mediatisation from within which have identified tensions between bureaucratic and party political values, but this has not included the United Kingdom. There are concerns that the traditional dividing line between government information and political propaganda has come under increasing pressure as a higher premium is placed on persuasion by both journalists and politicians battling for public attention in an increasingly competitive market. Within Whitehall, the arrival of Labour in 1997 after 18 years in opposition was a watershed for UK government communications, allowing the government to reconfigure its official information service in line with the party political imperative to deploy strategic communications as a defence against increasingly invasive media scrutiny. Public relations, in government as elsewhere, has grown in scale, scope and status, becoming institutionalised and normalised within state bureaucracies, but how has this affected the role, status and influence of the civil servants who conduct media management? Within the system of executive self-regulation of government publicity that is characteristic of Whitehall, government press officers must negotiate a difficult path between the need to inform citizens about the government’s programme, and demands by ministers to deploy privileged information to secure and maintain personal and party advantage in the struggle for power. Taking 1997 as a turning point, and through the voices of the actors who negotiate government news – mainly press officers, but also journalists and special advisers – this article examines the changing role and position of Whitehall press officers in what has become known as the age of political spin, finding that profound and lasting change in the rules of engagement has taken place and is continuing
