Cross-Border Impacts of Climate Policy Packages in North America
Description: We quantify cross-border effects of the recent climate mitigation policies introduced in Canada and the U.S., using the global general equilibrium model IMF-ENV. Notably, with the substantial emission reductions from Canada’s carbon tax-led mitigation policies and the U.S.’ Inflation Reduction Act, these two countries would bridge two-thirds of the gap toward their Nationally Determined Contribution (NDC) goals. While the broadly divergent policies are believed to elicit competitiveness concerns, we find the aggregate cross-border effects within North America to be very limited and restricted to the energy intensive and trade exposed industries. Potential carbon leakages are also found to be negligible. A more meaningful difference triggered by policy heterogeneity is rather domestic, especially with U.S. subsidies increasing energy output while the Canada model with a carbon tax would marginally decrease it. This analysis is complemented by a stylized model illustrating how such divergence can affect the terms of trade, but also how these effects can be countered by exchange rate flexibility, border adjustments or domestic taxation.

A Proposal to Improve Country-Level Data on Total Factor Productivity Growth
Description: The assumption behind popular data on national capital stocks, and therefore total factor productivity, is that countries were in a steady state in the first year that investment data became available. This paper argues that this assumption is highly implausible and is necessarily responsible for implausible data on the ratio of capital to output and productivity growth. It is not credible that countries with similar incomes had huge differences in their capital stocks. This paper claims, with evidence, that implausible features of the data can be greatly reduced by using data on electricity usage or national stocks of road vehicles.

Smooth Forecast Reconciliation
Description: How to make forecasts that (1) satisfy constraints, like accounting identities, and (2) are smooth over time? Solving this common forecasting problem manually is resource-intensive, but the existing literature provides little guidance on how to achieve both objectives. This paper proposes a new method to smooth mixed-frequency multivariate time series subject to constraints by integrating the minimum-trace reconciliation and Hodrick-Prescott filter. With linear constraints, the method has a closed-form solution, convenient for a high-dimensional environment. Three examples show that the proposed method can reproduce the smoothness of professional forecasts subject to various constraints and slightly improve forecast performance.

The Economic Impacts and the Regulation of AI: A Review of the Academic Literature and Policy Actions
Description: We review the literature on the effects of Artificial Intelligence (AI) adoption and the ongoing regulatory efforts concerning this technology. Economic research encompasses growth, employment, productivity, and income inequality effects, while regulation covers market competition, data privacy, copyright, national security, ethics concerns, and financial stability. We find that: (i) theoretical research agrees that AI will affect most occupations and transform growth, but empirical findings are inconclusive on employment and productivity effects; (ii) regulation has focused primarily on topics not explored by the academic literature; (iii) across countries, regulations differ widely in scope and approaches and face difficult trade-offs.

Deciphering the GloBE in a Low-Tax Jurisdiction
Description: 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.

The Dynamic Effects of Local Labor Market Shocks on Small Firms in The United States
Description: We use payroll data on over 1 million workers at 80,000 small firms to construct county-month measures of employment, hours, and wages that correct for dynamic changes in sample composition in response to business cycle fluctuations. We use this to estimate the response of small firms' employment, hours and wages following tighter local labor market conditions. We find that employment and hours per worker fall and wages rise. This is consistent with the predictions of the response to a demand shock in the well-known “jobs ladder” model of labor markets. To check this interpretation, we show our results hold when instrumenting for local demand using county-level Department of Defense contract spending. Correction for dynamic sample bias is important -- without it, the hours fall by only one third as much and wages increase by double.

Global Value Chain and Inflation Dynamics
Description: We study the inflationary impacts of pandemic lockdown shocks and fiscal and monetary stimulus during 2020-2022 using a novel harmonized dataset of sectoral producer price inflation and input-output linkages for more than 1000 sectors in 53 countries. The inflationary impact of shocks is identified via a Bartik shift-share design, where shares reflect the heterogeneous sectoral exposure to shocks and are derived from a macroeconomic model of international production network. We find that pandemic lockdowns, and subsequent reopening policies, were the most dominant driver of global inflation in this period, especially through their impact on aggregate demand. We provide a decomposition of lockdown shock by sources, and find that between 20-30 percent of the demand effect of lockdown/reopening is due to spillover from abroad. Finally, while fiscal and monetary policies played an important role in preventing deflation in 2020, their effects diminished in the recovery years.

High Inflation in the Baltics: Disentangling Inflation Dynamics and Its Impact on Competitiveness
Description: This paper identifies and quantifies the drivers of inflation dynamics in the three Baltic economies and assesses the effectiveness of fiscal policy in fighting inflation. It also analyzes the macroeconomic impact of inflation on competitiveness by focusing on the relationship between wages and productivity in the tradeable sector. The results reveal that inflation in the Baltics is largely driven by global factors, but domestic demand matters as well, suggesting that fiscal policy can play a role in containing inflation. Also, there is robust evidence of a long-run (cointegration) relationship between (real) wages in the tradeable (manufacturing) sector and productivity in the Baltics with short-term deviations self-correcting in Estonia and Lithuania only.

Can Fiscal Consolidation Announcements Help Anchor Inflation Expectations?
Description: In this paper, we use quarterly data and a novel database on fiscal policy consolidation announcements, for a sample of advanced economies and emerging markets to quantify the effects of fiscal tightening on inflation expectations. We find that fiscal consolidation announcements reduce inflation expectations over the medium-term (three and five-years ahead), but not in the short-term (one-year ahead). There is also some evidence that consolidation announcements reduce “disagreement” about expected future inflation at longer horizons. The inflation anchoring role of consolidation announcements is enhanced by the strength of a country’s fiscal and monetary frameworks, and when fiscal and monetary policy work in tandem. In addition, we find that initial conditions matter—inflation expectation’s response to consolidation announcements is larger in periods of high contemporaneous inflation. With these results in hand, we show that the effectiveness of fiscal consolidation in controlling realized inflation depends greatly on the response of inflation expectations to consolidation announcements. These results show that fiscal policy is crucial to anchor inflation expectations and a key element of a credible disinflationary process.

Climate Variability and Worldwide Migration: Empirical Evidence and Projections
Description: We estimate a bilateral gravity equation for emigration rates controlling for decadal weather averages of temperature, precipitation, droughts, and extreme precipitation in origin countries. Using the parameter estimates of the gravity equation, we estimate global, regional, and country-by-country emigration flows using different population and climate scenarios. Global emigration flows are projected to increase between 73 and 91 million in 2030-2039; between 83 and 102 million in 2040-2049; between 88 and 121 in 2050-59, and between 87 and 133 million in 2060-2069. Changes in emigration flows are mainly due to population growth in the origin countries.
