Generative artificial intelligence (gen AI) holds immense potential to boost productivity growth and advance public service delivery, but it also raises profound concerns about massive labor disruptions and rising inequality. This note discusses how fiscal policies can be employed to steer the technology and its deployment in ways that serve humanity best while cushioning the negative labor market and distributional effects to broaden the gains. Given the vast uncertainty about the nature, impact, and speed of developments in gen AI, governments should take an agile approach that prepares them for both business as usual and highly disruptive scenarios.

A Firm Lower Bound: Characteristics and Impact of Corporate Minimum Taxation
Aqib Aslam
and
Maria Delgado Coelho
This paper examines the role of minimum taxes and attempts to quantify their impact on economic activity. Minimum taxes can be effective at shoring up the corporate tax base and enhancing the perceived equity of the tax system, potentially motivating broader taxpayer compliance. Where political and administrative constraints prevent reforms to the standard corporate income tax, a minimum tax can help mitigate base erosion from excessive tax incentives and avoidance. Using a new panel dataset that catalogues changes in minimum tax regimes over time around the world, firm-level analysis suggests that the introduction or reform of a minimum tax is associated with an increase in the average effective tax rate of just over 1.5 percentage points with respect to turnover and of around 10 percent with respect to operating income. Minimum taxes based on modified corporate income lead to the largest increases in effective tax rates, followed by those based on assets and turnover.

Macroeconomic Effects of Tax Rate and Base Changes: Evidence from Fiscal Consolidations
Ms. Era Dabla-Norris
and
Frederico Lima
This paper examines the macroeconomic effects of tax changes during fiscal consolidations. We build a new narrative dataset of tax changes during fiscal consolidation years, containing detailed information on the expected revenue impact, motivation, and announcement and implementation dates of nearly 2,500 tax measures across 10 OECD countries. We analyze the macroeconomic impact of tax changes, distinguishing between tax rate and tax base changes, and further separating between changes in personal income, corporate income, and value added tax. Our results suggest that base broadening during fiscal consolidations leads to smaller output and employment declines compared to rate hikes, even when distinguishing between tax types.
