Horizontal policies in public procurement: a taxonomy

Public procurement is widely used to promote objectives of an economic, environmental and social nature, such as the economic development of disadvantaged social groups. This article elaborates a detailed taxonomy of such “horizontal” policies. This study is valuable, first, to facilitate analysis of the practical phenomenon of horizontal policies and of the policy implications of different approaches and, second, to illuminate and develop the relevant regulatory frameworks under national and international regimes. The taxonomy is based on three key distinctions between the following: 1. policies limited to securing compliance with legal requirements and those that go beyond such requirements; 2. policies applied only to the contract awarded and those that go beyond it; and 3. nine different mechanisms by which policies are implemented in the procurement process.
