Macroeconomic Effects Of Tax Rate And Base Changes

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.

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 yield, motivation, and announcement and implementation dates of more than 2,000 tax measures across 10 OECD countries. Using this data, we then analyze the macroeconomic impact of tax changes, distinguishing between tax rate and tax base changes, and further differentiating between changes in personal income, corporate income, and value added taxes. 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.

We analyze the effects of dividend taxation in a general equilibrium business cycle model with an occasionally-binding investment credit limit. Permanent dividend tax reforms distort capital investment decisions in the binding long-run equilibrium, but are neutral otherwise. Temporary unexpected tax cuts stimulate shortterm real activity in the credit-constrained economy, yet produce contractionary macroeconomic outcomes in the slack regime. The occasionally-binding constraint reconciles the `traditional' and `new' views of dividend taxation, and highlights the importance of measuring the firm's initial borrowing position before enacting tax reforms. Finally, permanently lower dividend taxes dampen financial business cycles, and help to explain macroeconomic asymmetries.

This paper uses a multi-region, forward-looking, DSGE model to estimate the macroeconomic impact of a tax reform that replaces a corporate income tax (CIT) with a destination-based cash-flow tax (DBCFT). Two key channels are at play. The first channel is the shift from an income tax to a cash-flow tax. This channel induces the corporate sector to invest more, boosting long-run potential output, GDP and consumption, but crowding out consumption in the short run as households save to build up the capital stock. The second channel is the shift from a taxable base that comprises domestic and foreign revenues, to one where only domestic revenues enter. This leads to an appreciation of the currency to offset the competitiveness boost afforded by the tax and maintain domestic investment-saving equilibrium. The paper demonstrates that spillover effects from the tax reform are positive in the long run as other countries’ exports benefit from additional investment in the country undertaking the reform and other countries’ domestic demand benefits from improved terms of trade. The paper also shows that there are substantial benefits when all countries undertake the reform. Finally, the paper demonstrates that in the presence of financial frictions, corporate debt declines under the tax reform as firms are no longer able to deduct interest expenses from their profits. In this case, the tax shifting results in an increase in the corporate risk premia, a near-term decline in output, and a smaller long-run increase in GDP.

This paper examines the role of tax policy reforms in enhancing fiscal shock smoothing in a panel of 13 OECD economies during the period 1980-2017. The results suggest that tax reforms, in particular those that broaden the tax base, significantly enhance the ability of fiscal policy to mitigate the impact of growth shocks on disposable income. We find that the magnitude of shock smoothing increases from an average of 2 percent to 3-31⁄2 percent following the reform. The effects are considerably higher for tax base than tax rate changes, and also higher for indirect tax than direct tax changes. The effects are symmetric—that is, the increase in shock smoothing following a reform expanding the tax base (rate) is similar to the decline in shock smoothing after a reform narrowing the tax base (rate). Tax elasticity, collection efficiency, and the progressivity of the tax system are important channels through which tax reforms affect fiscal stabilization.

This paper assesses the macroeconomic and distributional impact of personal income tax (PIT) reforms in the U.S. drawing on a multi-sector heterogenous agents model in which consumers have non-homothetic preferences and sectors differ in terms of their relative labor and skill intensity. The model is calibrated to key characteristics of the US economy. We find that (i) PIT cuts stimulate growth but the supply side effects are never large enough to offset the revenue loss from lower marginal tax rates; (ii) PIT cuts do “trickle-down” the income distribution: tax cuts stimulate demand for non-tradable services which raise the wages and employment prospects of low-skilled workers even if the tax cut is not directly incident on them; (iii) A revenue neutral tax plan that reduces PIT for middle-income groups, raises the consumption tax, and expands the Earned Income Tax Credit can have modestly positive effects on growth while reducing income polarization; (iv) The growth effects from lower income taxes are concentrated in non-tradable service sectors although the increased demand for tradable goods generate positive spillovers to other countries; (v) Tax cuts targeted to higher income groups have a stronger growth impact than tax cuts for middle income households but significantly worsen income polarization, even after taking into account trickle-down effects and an expansion of the Earned Income Tax Credit.

This document,1 prepared by the staff of the Joint Committee on Taxation (“Joint Committee staff”), provides an analysis of the macroeconomic effects of a proposal to modify both the individual and corporate income tax by broadening their tax bases and changing statutory tax rates. This analysis is based on the proposal as it corresponds to the estimates presented in Estimated Revenue Effects of the “Tax Reform Act of 2014” (JCX-20-14), February 26, 2014 (and described in Discussion Draft CAMP_041). The following analysis uses both an overlapping generations lifecycle model and the Joint Committee staff's Macroeconomic Equilibrium Growth model to simulate the macroeconomic effects of the proposal. In general, the lower effective marginal tax rates resulting from the combination of lower statutory tax rates and changes to the definition of taxable income provide an incentive for increased labor effort, and under some modeling assumptions for some years, increased business investment. Relative to present law, the policy provides an incentive for increased consumer purchases of goods and services by increasing after-tax income of households. This effect can be important when the economy is operating below full capacity. The extent of both supply and demand effects depends on the sensitivity of individual labor choices to changing effective marginal rates, the responsiveness of individual savings choices to changes in the after-tax return on earnings from investment, and the responsiveness of businesses to changing incentives for overall investment and the location of investment and taxable profits in the United States. In addition, the projected impacts of the proposal on the economy depend on assumptions about the monetary policy response by the Federal Reserve Board. In general, under most modeling assumptions, the proposal is projected to increase overall economic activity as measured by changes in gross domestic product (“GDP”) relative to the present law baseline over the 10-year budget period.
