Corporate Taxation and Productivity Catch‐Up: Evidence from European Firms

In this paper, we explore whether higher corporate tax rates, because they lower the after‐tax returns to productivity‐enhancing investments, reduce the speed with which small firms converge to the productivity frontier. Using data for 11 European countries, we find evidence that their productivity catch‐up is slower when the statutory corporate tax rates are higher. In contrast, we find that large firms are instead affected by effective marginal rates. Using the reduced‐form model of productivity convergence of Griffith et al . (2009, Journal of Regional Science 49 , 689–720), our results are robust to a host of robustness checks and a natural experiment that exploits the 2001 German tax reforms.     

The growth effects of tax rates in the OECD

This paper explores the merits of macro‐ and micro‐based tax rate measures within an open economy “fiscal policy and growth” model. Using annual data for 15 OECD countries we find statistically small, non‐robust long‐run growth effects of macro‐based average tax rates on capital income and consumption, but some evidence for average labour income tax effects. Changes in “micro” marginal income tax rates at both the personal and corporate levels yield statistically robust GDP responses of modest size. Both domestic and foreign corporate taxes appear relevant. In general, tax effects on GDP operate largely via factor productivity rather than factor accumulation.     

Foreign (in)direct investment and corporate taxation

Abstract Foreign investments of multinational firms are often complex in that they involve conduit entities. In particular, a multinational can pursue either a direct or an indirect investment strategy, where the latter involves an intermediate corporate entity and is associated with enhanced opportunities for international tax planning. As a consequence, in the case of indirect investments, the role of corporate taxation in destination countries may change. This paper investigates the effects of corporate taxation on foreign investment decisions of German multinationals, taking explicitly into account that firms choose in a first stage the investment regime (direct vs. indirect). The empirical findings, consistent with theoretical predictions, suggest that tax effects differ according to whether the investment is direct or indirect.     

Identifying Laffer Bounds: A Sufficient‐Statistics Approach with an Application to Germany

We derive a simple sufficient‐statistics test for whether a nonlinear tax‐transfer system is second‐best Pareto efficient. If it is not, then it is beyond the top of the Laffer curve and there exists a tax cut that is self‐financing. The test depends on the income distribution, extensive and intensive labor supply elasticities, and income effect parameters. A tax‐transfer system is likely to be inefficient if marginal tax rates are quickly falling in income. We apply this test to the German tax‐transfer system, and we find that the structure of effective marginal tax rates is likely to be inefficient in the region where transfers are phased out.     

Choices and Constraints over Retirement Income Streams: Comparing Rules and Regulations*

The new Simplified Superannuation regulations for Australian superannuation provide tax concessions to retirement income streams which comply with legislated minimum drawdown rules. We evaluate these new drawdown rules against four alternatives, including three formula‐based ‘rules of thumb’ used by financial planners. We find that the new regulations are a substantial improvement on the previous rules for allocated pensions and, when compared with the formula‐based rules, are a good compromise in terms of simplicity, adequacy and risk. We also find that welfare is lower for most individuals who follow the Simplified Superannuation rules compared with welfare under an optimal path or a simple fixed percentage drawdown rule, but that outcomes could be improved through a further simplification of the new rules.     

The repatriation incentive of the foreign dividend exemption system

Due to the high taxation of domestic corporate income, Japanese multinational enterprises have avoided to repatriate foreign profits to Japan for quite some time. As a consequence, the Japanese government introduced a new taxation system in 2009 – the so called dividend exemption system – which was aimed at reducing the effective tax burden of foreign dividends of Japanese multinational companies in order to increase tax revenue and stimulate economic growth. Applying a theoretical framework which allows comparing the repatriation incentive of the old and new Japanese tax systems, we find that in the long-run the tax regime change fails to incentivize foreign subsidiaries to repatriate foreign profits. Especially subsidiaries with high leverage located in countries with low corporate taxes and low dividend taxes might reinvest rather than distribute their earnings in the dividend exemption method.     

Financial Student Aid and Enrollment in Higher Education: New Evidence from Germany*

Means‐tested student aid might affect enrollment in higher education. To derive the potential influence of student aid, we use a tax‐benefit microsimulation model. The effect is a non‐linear function of parental income, with variation as a result of bracket creeping and various reforms. Therefore, the effect of student aid on enrollment can be separated from the effects of income and other family characteristics. Using the German Socio‐Economic Panel, we find a small but significant positive effect, similar in size to the effects reported in previous studies for European countries but smaller than in the US.     

Supply-Side Economics of Germany's Year 2000 Tax Reform: A Quantitative Assessment

Abstract. The paper provides an assessment of supply‐side economics following Germany's year 2000 tax reform. Investigated are a corporate tax cut, deteriorating depreciation allowances and imputation rules, and a private income tax cut. For this purpose, a neoclassical growth model is augmented by various fiscal policy parameters and endogenous corporate finance and calibrated with German data. The model is used to evaluate consequences of Germany's tax reform on production, firm finance and leverage, investment, consumption and welfare of a representative household.     

Age‐related Optimal Income Taxation*

In most countries, average income varies with age. In this paper we investigate if and how it is possible to enhance the redistributive mechanism by relating tax payments to age. Using an OLG model where some individuals are low skilled all their life while others are low skilled when young but high skilled when old, we first show how an age dependent optimal income tax can Pareto improve upon an age independent income tax. We then characterize the optimal age dependent income tax. A tax on interest income is part of the optimal tax structure.     

HUMAN CAPITAL FORMATION AND TAX EVASION

A strictly risk‐averse individual with an exogenous gross income in period one can acquire human capital in the same period and evade taxes. Period‐two income rises with educational investments in period one and can also be hidden from tax authorities. It is shown that a greater tax deductibility of educational investments and higher individual ability induce a positive correlation between tax evasion and educational investments in period two, whereas the relationship in period one is ambiguous. These theoretical predictions can explain diverse empirical findings on the correlation between education and tax evasion.     

The impact of thin‐capitalization rules on the location of multinational firms’ foreign affiliates

This paper examines how restrictions on the tax deductibility of interest cost affect location choices of multinational corporations (MNCs). Many countries have introduced so‐called thin‐capitalization rules (TCRs) to prevent MNCs from shifting their tax base to countries with lower tax rates. As of 2012, in our sample of 172 countries, 61 countries have implemented a TCR. Using information on nearly all new foreign investments of German MNCs, we provide a number of new and interesting insights in how TCRs affect the decision of where to locate foreign entities. In particular, stricter TCRs are found to negatively affect location choices of MNCs. Our results include estimates of own‐ and cross‐elasticities of location choice and also novel results on the relative importance of tax base vs. tax rate effects. We finally provide estimates for different uncoordinated as well as coordinated policy scenarios.     

Progressive taxation,tax exemption,and corporate liquidation policy

This paper develops a real options model of a firm that operates in continuous time with an infinite horizon. The firm receives stochastic profit flows that are subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold that makes the average tax rate increase with the tax base. The firm possesses an option to liquidate its operation, which is optimally exercised when the firm's profit flow reaches an endogenously determined threshold level (the liquidation trigger) from above. We show that the firm's liquidation trigger under progressive taxation increases with either a reduction in the tax exemption threshold or an increase in the corporate income tax rate. Corporate income taxes are thus not neutral when tax schedules are progressive.     

Investment behavior and the biased perception of limited loss deduction in income taxation

We use a laboratory experiment to study the extent to which investors’ choices are affected by limited loss deduction in income taxation. We first compare investment behavior in the no tax baseline to a tax control setting, in which the income from investments is taxed. We find that investors significantly reduce their risk-taking as predicted by theory. Next we compare the baseline investment choices to choices under three different types of income taxation. We observe that risk-taking is significantly increased with partial and with capped loss deduction, but is unaffected by a tax system that allows no loss deduction. Since in all these treatments the after tax outcomes of the prospects were identical, we conjecture that investors have a positively biased perception of partial and capped loss deduction that promotes their willingness to take risks.     

Progressive taxation and corporate liquidation policies with mean-reverting earnings

This paper develops a real options model of an all-equity financed firm that receives mean-reverting earnings and is subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold such that the firm pays no corporate income taxes should its earnings be less than this threshold. The firm possesses a perpetual option to liquidate its operation for a deterministic salvage value at any time. We show that the firm optimally exercises the liquidation option at the first instant when its earnings reach an endogenously determined threshold (the liquidation trigger) from above. Using numerical analysis, we show that the liquidation trigger is higher or lower than the exogenously given tax exemption threshold, depending on whether the tax exemption is below or above a unique critical level, respectively. We further show that the liquidation trigger is strictly decreasing for all tax exemption thresholds less than the critical level, and can be hump-shaped for all tax exemption thresholds greater than the critical level, especially when the salvage value is small. Corporate income taxes as such are not neutral when tax schedules are progressive.     

International corporate taxation and U.S. multinationals' behaviour: an integrated approach

Abstract .  This paper explores the effects of corporate taxation on U.S. capital invested abroad and on tax planning practices. The econometric analysis first indicates that investment is strongly influenced by average tax rates, with a magnified impact particularly for low-tax rates, implying that the attractiveness of low-tax countries is not weakened by anti-deferral rules and cross-crediting limitations. Further explorations suggest that firms report higher profit, higher Subpart F income, and are less likely to repatriate dividends when they are located in low-tax jurisdictions. Finally, when the role of effective transfer pricing regulations is estimated, it appears that low degrees of law enforcement are associated with higher income shifting.     

How elastic are national corporate income tax bases in OECD countries? The role of domestic and foreign tax rates

Abstract To what extent do reductions in corporate income tax (CIT) rates attract foreign tax bases? What are the revenue implications of a unilateral tax reduction when tax bases are internationally mobile? These questions are explored using annual data from 17 OECD countries spanning the period 1982 to 2005. Controlling for fixed country effects, year effects, and country time trends, and subjecting our results to an extensive robustness analysis, we find (i) a country’s aggregate reported corporate profits are negatively and significantly affected by CIT rate reductions in neighbouring countries; (ii) a unilateral reduction in the domestic CIT rate results in lower domestic CIT revenues.     

THE INCOME REDISTRIBUTION EFFECT OF CHINA'S PERSONAL INCOME TAX: WHAT THE MICRO‐DATA SAY

This article uses continuous micro‐level data to investigate the income redistribution effect of the personal income tax (PIT) in China beginning in 1997. We find that the average tax rate plays a larger role in determining the income redistribution effect of PIT than tax progressivity does. Although tax progressivity decreased as a result of rising personal incomes and a constant PIT policy prior to 2005, the income redistribution effect of the PIT improved as a result of the higher average tax rate. The tax reform beginning in 2006 increased tax progressivity while decreasing the average tax rate, thereby weakening the income redistribution effect of the PIT. Further analysis indicates that the middle‐income group was the only net loser before 2005, but it benefited from the PIT policy reform. A cross‐country comparison shows that China has a lower PIT burden and higher progressivity than developed countries; in fact, China's levels of progressivity and tax burden are similar to those of Latin American countries.

The dual nature of public goods and congestion: the role of fiscal policy revisited

Abstract The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption‐based instruments in conjunction with the income tax. An income tax‐financed increase in government spending dominates both lump‐sum and consumption tax‐financing. Replacing the lump‐sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax. These results contrast sharply with the literature, where the consumption tax is generally viewed as the least distortionary source of public finance.     

TAXES,INCOME, AND RETIREMENT SAVINGS: DIFFERENCES BY PERMANENT AND TRANSITORY INCOME

This article examines the determinants of and benefits from saving for retirement in tax‐preferred accounts by permanent and transitory income levels. We find that higher incomes (both permanent and transitory) are associated with a greater probability to contribute and larger contributions. We also find that tax benefits for retirement savings increase strongly with income, although the increase is slightly smaller when taxpayers are ranked by their permanent (rather than current) income. In addition, we find that a large portion of the benefits from the Saver's Credit go to taxpayers who would not be eligible based on their permanent income. Finally, we find that recent tax changes (including the introduction of the Saver's Credit) significantly increased contributions among low‐income households, although the effect was centered among those with only transitorily low income.

After‐tax Valuation of Convertible Bonds and Participation Exemption

This paper studies the after‐tax valuation of convertible bonds in the light of Europe's participation exemption (PEX) rules and International Financial Reporting Standards (IFRS). The focus is on Italy's representative case. PEX rules exempt from company taxation capital gains realized by companies selling stocks. PEX rules raise the value of convertibles as investor companies can strategically convert the bond into stock to enjoy PEX. Historical cost‐based national accounting standards imply taxation upon realization and valuable tax timing options (TTOs). ‘Fair value’ based IFRS entail mark‐to‐market taxation, which ‘kills’ TTOs, but investor companies can convert the bond early in order to enjoy PEX. Early conversion can be valuable.
