So, how can countries design industrial policies to maximize their effects and limit the associated trade-offs?
Impact on targeted sectors
For a start, the effectiveness of industrial policies depends on industry-specific characteristics that can be hard to determine in advance. Our simulations show that industrial policy can help boost domestic sectors when productivity scales up with output. This could reflect workers learning on the job or industries becoming more efficient with scale.
Countries can use a mix of subsidies and trade protections to promote domestic production in strategic industries. In principle, early support through industrial policy can deliver dynamic gains and long-lasting productivity improvements in sectors that become more efficient with experience. Because production costs decrease as volume grows, targeted industries can learn by doing and become competitive globally.
However, these industrial policies come with significant trade-offs: consumers can face higher prices for a prolonged period, and governments can incur substantial budgetary costs. Success also isn’t guaranteed, because it depends on industry-specific traits that are often difficult to predict. Catching up technologically may not be achievable if companies are too far behind, learn slowly, or domestic firms can’t readily access large markets, for example through exports.
Empirically, our analysis of the effects of recent industrial policies suggests industrial policy is associated with better economic outcomes in targeted industries, particularly in countries with strong institutions. But the gains are small.
Direct subsidies to an industry are associated with about a 0.5 percent improvement in value added and 0.3 percent higher total factor productivity three years after implementation, reflecting higher capital accumulation and employment. These improvements are modest compared with sample average industry value added growth of 6.5 percent per year and total factor productivity growth of about 4 percent per year.
Moreover, earlier IMF analysis reaffirms larger gains can come from structural reforms to improve the overall business environment and better enable credit access for all firms.
Aggregate impacts
While industrial policy can help specific industries, translating these into broader economic benefits can be challenging.
Our multi-sector, multi-country quantitative model shows that employment, productivity and output all improve in targeted industries. But, because resources are drawn away from untargeted sectors, those sectors end up shrinking and losing productivity, potentially delivering a negative impact on aggregate productivity. So, even if targeted support can boost priority sectors, and increase resilience and independence, our analysis suggests it can also create misallocation of resources and dampen aggregate outcomes, leaving the economy worse off.
Calibrating policy
Our findings highlight the importance of carefully designing and implementing industrial policy. Governments should consider the risks of wasteful spending, especially when debt is elevated and fiscal space limited. They should weigh the opportunity cost of industrial policy against economy-wide reforms that can often boost economic outcomes without relying on precise sector targeting or large fiscal costs. And they should recognize and manage trade-offs explicitly. Although not the focus of this chapter, large-scale industrial policy can also have cross-country spillovers, and trigger retaliation by trading partners.
Countries that do pursue industrial policies should include mechanisms for regular evaluation and recalibration, all underpinned by a strong institutional and macroeconomic framework. Policymakers should encourage market discipline through vigorous domestic and international competition.
Doing so will increase the likelihood that industrial policy delivers on its promise—without compromising fiscal sustainability or economic efficiency.
