An identifiable technique of collective action — a binding regulation, an executive order, a voluntary code, a technical standard, a treaty, or similar — by which a public authority structures behaviour to address a policy problem. Instrument choice is itself a substantive policy decision, not a downstream implementation detail.
Definition and scope
The canonical public-policy literature treats a policy instrument as a discrete 'tool of government' deployed to organise collective action. Hood's seminal NATO typology (Hood 1983, The Tools of Government, ch. 1-2) groups instruments by the resource base they exploit — Nodality (information), Authority (legal command), Treasure (fiscal transfer), and Organisation (direct provision). Salamon (2002, The Tools of Government: A Guide to the New Governance, pp. 1-47) extends the frame to a 'third-party governance' world in which most instruments are distributed delivery mechanisms (grants, contracts, vouchers, tax expenditures, regulation), and Howlett (2011, Designing Public Policies, ch. 3-5) operationalises instrument choice as constrained by information, capability, and political variables. The political-sociology tradition (Lascoumes & Le Galès 2007, Governance 20(1): 1-21) goes further: instruments are not neutral techniques but 'a particular form of materialisation of state power' (pp. 4-5) that produce effects independently of their stated objectives — meaning instrument choice is policy substance. In AI governance, the patchwork of binding regulation (EU AIA), executive orders (US EO 14110), voluntary codes (G7 Hiroshima), technical standards (NIST AI RMF), international treaties (CoE AI Convention), and resolutions (UN A/RES/78/265) is best understood not as incoherence but as the predicted response to what Marchant et al. (2011, The Growing Gap Between Emerging Technologies and Legal-Ethical Oversight, ch. 1) call the 'pacing problem' — formal regulation lags capability development by years, so jurisdictions sequence soft-law (norm-setting, capability evaluation) ahead of hard-law (binding obligations). Anderljung et al. (2023, 'Frontier AI Regulation,' arXiv:2307.03718, §3) argue the multi-instrument mix is necessary under dual-use indeterminacy; critics argue it enables regulatory arbitrage. The seven InstrumentKind values in this wiki map onto Hood's NATO scheme as follows: binding_regulation + executive_order + international_treaty = Authority; technical_standard = Authority+Nodality hybrid; policy_statement + voluntary_code + resolution = Nodality/sermons. Market-based instruments (tradeable permits, Pigouvian taxes) and pure information instruments (registries, labels) are present in AI governance but not yet first-class categories in this catalog.

Editorial note
Foundational concept article for the policy_instrument domain — defines the category that every INSTRUMENTS entry instantiates. When citing 'policy instrument' in other wiki articles without further qualifier, default to the Hood / Salamon / Howlett synthesis; reserve Lascoumes & Le Galès when the article's argument turns on instruments-as-power rather than instruments-as-techniques. The seven InstrumentKind values do NOT yet include market-based or pure-information instruments; if a future AI-governance instrument falls outside the seven, expand InstrumentKind rather than forcing a mis-fit.
