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.

Cash Flow Analysis of Fiscal Regimes for Extractive Industries
Thomas Benninger
,

,
Eduardo Camero Godinez

Nate Vernon
Mining and petroleum projects share characteristics distinguishing them from other sectors of the economy, which has led to the use of dedicated fiscal regimes for these projects. The IMF’s Fiscal Affairs Department uses fiscal modeling to evaluate extractive industry fiscal regimes for its member countries, and trains country officials on key modeling concepts. This paper outlines important preconditions needed for effective fiscal modeling, key evaluation metrics, and emphasizes the importance of transparent modeling practices. It then examines the modeling of commonly-used fiscal instruments and highligts where their economic impact differs, and how fiscal models can inform fiscal regime design.

Deciphering the GloBE in a Low-Tax Jurisdiction
Shafik Hebous
,
Cory Hillier
, and
Andualem Mengistu
Pillar Two rules of the Inclusive Framework agreement on a minimum corporate tax (known as ‘Global Anti-Base Erosion Rules’, for short GloBE) have important implications for the design of the corporate income tax. This chapter discusses these implications particularly from the perspective of low-tax jurisdictions. It argues that it is not possible to design a system that always guarantees generating exactly the bare minimum tax intended by the rules and motivates that this should not be the policy objective anyway. Importantly, if no profit tax already exists, countries need to consider whether to adopt one, and if yes, in what form. There is a case for introducing a general profit tax beyond the GloBE rules, together with a qualifying GloBE domestic minimum top-up tax as a backstop. The familiar alternatives of efficient economic rent tax designs, however, are no longer equivalent under the GloBE. In practice, given the specifics of the rules, an efficient rent tax on in-scope multinationals cannot be combined with a statutory tax rate below a certain cutoff, because the minimum tax becomes always binding. Under the GloBE, immediate expensing particularly maintains the time-value of fully deducting the cost of investment, without impacting the GloBE effective tax rate.

Efficient Economic Rent Taxation under a Global Minimum Corporate Tax
Shafik Hebous
and
Andualem Mengistu
The international agreement on a corporate minimum tax is a milestone in global corporate tax arrangements. The minimum tax disturbs the equivalence between otherwise equivalent forms of efficient economic rent taxation: cash-flow tax and allowance for corporate equity. The marginal effective tax rate initially declines as the statutory tax rate rises, reaching zero where the minimum tax is inapplicable, and increases thereafter. This kink occurs at a lower statutory rate under cash-flow taxation. We relax the assumption of full loss offset; provide a routine for computing effective rates under different designs; and discuss policy implications of the minimum tax.

Searching for Wage Growth: Policy Responses to the “New Machine Age”

The current wave of technological revolution is changing the way policies work. This paper examines the growth and distributional implications of three policies when “robot'' capital (a broad definition of robots, Artificial Intelligence, computers, big data, digitalization, networks, sensors and servos) is introduced in a neoclassical growth model. 1) cuts to the corporate tax rate; 2) increases in education spending; and 3) increases in infrastructure investment. We find that incorporating “robot'' capital into the model does make a big difference to policy outcomes: the trickle-down effects of corporate tax cuts on unskilled wages are attenuated, and the advantages of investment in infrastructure, and especially in education, are bigger. Based on our calibrations grounded on new empirical estimates, infrastructure investment and corporate tax cuts dominate investment in education in a "traditional" economy. However, in an economy with “robots” the infrastructure investment dominates corporate tax cuts, while investment in education tends to produce the highest welfare gains of all. The specific results, of course, may depend on the exact modeling of the technological change, but our main results remain valid and can provide more accurate welfare rankings.

International Tax Spillovers and Tangible Investment, with Implications for the Global Minimum Tax
Mr. Michael Keen
,
Ms. Li Liu
, and
Hayley Pallan
This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host’s rate; larger than previous consensus values (attributed to a systematic bias from FDI data); and consistent with ‘implicit’ profit shifting through real investment (rather than ‘paper’ profit shifting). Contrary to much policy discussion, the results also imply that: Host countries’ marginal effective tax rates have at best a weak effect on real investment; those elsewhere have none; and, applied to the prospective global minimum tax, inward tangible investment in most sample countries will increase.

Unpleasant Surprises? Elections and Tax News Shocks
Mr. Antonio David
and
Can Sever
Unanticipated changes in tax policy are likely to have different macroeconomic effects compared to anticipated changes due to several mechanisms, including fiscal foresight and policy uncertainty. It is therefore important to understand what drives such policy surprises. We explore the nature of unanticipated tax policy changes by focusing on a political economy determinant of those events, namely the timing of elections. Using monthly data for 22 advanced economies and emerging markets over the period 1990-2018, we show that implementation lags tend to be significantly longer for tax policy change announcements that are made during the pre-election periods, thereby leading to a lower likelihood of “tax news shocks”. We also find that implementation lags become much shorter for tax policy changes that are announced in the aftermath of elections, generating more frequent tax news shocks. This pattern remains similar for different tax measures or types of taxes. The findings are robust to a number of checks, including alternative definitions of tax news shocks, or to controlling for various economic and institutional factors.

How to Design a Presumptive Income Tax for Micro and Small Enterprises
Jean-François Wen
Turnover taxes are prevalent in developing countries as a simple form of presumptive taxation of business income. Such simplified tax regimes can reduce the relatively high compliance costs of micro and small enterprises, which might otherwise discourage entrepreneurs from formalizing their activities and paying taxes. The note addresses design issues for a turnover tax regime—which taxes it replaces, what the criteria are for eligibility, how to determine the optimal threshold, and how to set the tax rate. A key observation is that, although low turnover tax rates may incite larger firms to artificially reduce their sales, the rate should also not be so high as to discourage formalization of activities. A table of tax rates and turnover thresholds observed internationally is provided. The note concludes by suggesting analytical steps to guide practitioners in designing turnover tax regimes.

A Deep Dive into Tax Buoyancy: Comparing Estimation Techniques in a Large Heterogeneous Panel
Antoine Cornevin
,
Mr. Juan C Flores
, and
Juan Pablo Angel
This paper provides new empirical evidence on tax buoyancy (tax revenues responsiveness to changes in economic activity) over the period 1990-2020 using a large panel of 185 countries. This study compares short-term and long-term buoyancy coefficients for total tax revenues and different individual taxes by reviewing and contrasting a range of estimators. Our results broadly confirm the main body of the literature on long-term buoyancy hovering around one. We find evidence of lower estimates for short-term buoyancy relative to previous literature, suggesting a limited automatic stabilization power of taxes. As a robustness exercise, in addition to changes in tax rates, we introduce novel control variables for tax exemptions and bases to disentangle discretionary from automatic tax revenue changes. The marginal changes in the results when controlling for policy actions suggest that, on average, the economic cycle does not necessarily influence tax reforms.

Personal Income Taxes in the Middle East and North Africa: Prospects and Possibilities
Mario Mansour
and
Eric M. Zolt
Personal income taxes (PITs) play little or no role in the Middle East and North Africa, often yielding less than 2 percent of GDP in revenue—with the exception of few North African countries. This paper examines how PITs have evolved in recent decades, and what they might look like in the next 20 years. Top marginal tax rates on labor and business income of individuals have declined substantially, a trend that mirrors reductions in advanced and developing economies. Taxation of passive capital income has changed very little, and the revenue intake from this source remains low throughout the region (less than 1 percent of GDP on average and concentrated in oil-importing non-fragile states). Social security contributions (SSC) have increased in importance in nearly all MENA countries, and some countries have introduced additional payroll taxes. The combination of reduced marginal tax rates, light taxation of income from capital and business activities, and increase of SSC, have resulted in income tax systems that create disincentives to work and incentives for informality, and contribute little to government revenue and income redistribution. Given differences in economic and political structures, demographics, and starting points, the path to PIT/SSC reforms will vary across the region. Countries with relatively mature PIT/SSC systems, where revenue performance has improved in the past two decades, will increasingly need to balance the revenue and equity objectives against effciency objectives (in particular labor market incentives and infromality). Countries with no PITs will have to weigh whether a consumption tax/SSC system that mimic a flat tax on labor income is sufficient to diversify revenue away from oil and whether to adopt PITs to address rising income and wealth inequality. Finally, fragile states, who face more political volatility and weaker fiscal institutions, will have to focus on simplicity of tax design and collection to be able to raise revenue from PITs.
