Accountability in the Shadow of Hierarchy: The Horizontal Accountability of Agencies

In the Netherlands, new accountability arrangements are created as remedies for the accountability deficit of agencies. These arrangements are of a ‘horizontal’ nature, as the agencies account for their behaviour towards accountees that are not their hierarchical superiors: clients, stakeholders or peers. This paper provides an inventory and qualitative assessment of horizontal accountability arrangements. It is argued that they have added value because they stimulate learning. However, horizontal accountability is not a substitute for hierarchical accountability. Horizontal accountability arrangements operate ‘in the shadow of hierarchy’: they gain significance through complex interactions with traditional forms of accountability.
