Horizontal Industrial Policy

Horizontal industrial policy refers to state interventions designed to raise the overall productivity, competitiveness, or innovation capacity of an economy without favoring any particular sector, firm, or technology. It is typically contrasted with vertical (or selective) industrial policy, which targets specific industries — semiconductors, shipbuilding, electric vehicles — through tailored subsidies, tariffs, or state ownership.

Typical horizontal instruments include:

• General R&D tax credits available to any firm that conducts qualifying research.
• Education and vocational training programs that build a broad skills base.
• Infrastructure investment in transport, electricity, and broadband.
• Competition policy and regulatory simplification that lower entry costs.
• Export promotion agencies and trade-finance facilities open to all exporters.
• SME support schemes based on firm size rather than sector.

The intellectual appeal of the horizontal approach rests on the idea that governments lack the information to identify winning industries and are prone to capture by incumbents — a critique associated with Anne Krueger's work on rent-seeking and with much of the World Bank's policy advice during the 1980s and 1990s. Horizontal measures are also generally easier to reconcile with WTO rules, particularly the Agreement on Subsidies and Countervailing Measures, because they are less likely to be "specific" subsidies subject to challenge.

The distinction is not always clean in practice. A "horizontal" R&D credit weighted toward manufacturing, or training funds concentrated in green skills, effectively channels support to particular sectors. Recent debates — around the US CHIPS and Science Act, the EU Green Deal Industrial Plan, and reshoring strategies — have revived interest in explicitly vertical tools, leading scholars such as Dani Rodrik and Reka Juhasz to argue that the horizontal/vertical binary is analytically less useful than asking whether industrial policy is well-designed, conditional, and accountable.
