Personal income tax mimicry: evidence from international panel data

This paper investigates personal income tax (PIT) mimicry at the international level. It is the first to empirically investigate the extent to which PIT mimicry varies along the tax schedule and the first to include nations which are not part of the OECD. We use data on international personal income tax schedules from the world tax indicators to estimate marginal and average tax rates at various multiples of per capita gross domestic product (GDP). These tax rates are then used to estimate the extent to which countries respond to their neighbors’ PIT policy. We find evidence of PIT mimicry using a balanced panel of 53 countries over 24 years. This finding is strongest for tax rates at lower multiples of per capita GDP and survives several robustness checks.     

The effectiveness of tax incentives in attracting investment: panel data evidence from the CFA Franc zone

In this paper we investigate to what extent tax incentives are effective in attracting investment in Sub-Saharan Africa. We test the neo-classical investment theory prediction that tax incentives, by lowering the user cost of capital, raise investment. Next to tax incentives, we also estimate the impact on investment of other investment climate variables that are under direct control of the government, such as the transparency and complexity of the tax system, and the legal protection of foreign investors. In developing countries these variables might be as important as or even more important than the tax variables themselves.     

Endogenous choice on tax instruments in a tax competition model: unit tax versus ad valorem tax

This paper analyzes an endogenous choice problem with regard to tax instruments in a capital tax competition model. Using a symmetric and two-region model of tax competition, where each region is allowed to choose either a unit or an ad valorem tax, we show that selecting a unit tax as a policy instrument is the dominant strategy.     

The stock market effects of a securities transaction tax: Quasi-experimental evidence from Italy

In the aftermath of the financial crisis, in several countries new levies on the financial sector have been proposed and in some cases implemented. We focus in particular on the recent introduction of a securities transaction tax (STT) in Italy. A peculiarity of the Italian STT is that it only concerns stocks of corporations with a market capitalization above € 500 million. We exploit this feature via a differences-in-differences approach – comparing taxed and non-taxed stocks before and after the introduction of the tax – and via a regression discontinuity design – comparing the performance of stocks just above the threshold with those just below. Focusing on the regulated market, we find that the new tax reduced liquidity, but it left transaction volumes and returns substantially unaffected. There is also evidence – although not conclusive – that the tax increased volatility.     

The revenue and base effects of local tax hikes: evidence from a quasi-experiment

Due to a reform of the local equalization scheme in 2003, a set of municipalities in the German state of North Rhine-Westphalia (NRW) increased their local property and business tax rates by one to two percentage points, while the remaining municipalities kept their rates constant. I use this variation across municipalities and over time to study the revenue and base effects of local property and business tax hikes in a generalized difference-in-differences design. The results suggest that the property tax hikes had even in the long-run a revenue elasticity of unity. Accordingly, I find no adverse effects on property tax bases. For the business tax, I find no significant effects on revenues and bases. Furthermore, there are also no effects on broader economic outcomes such as local employment, firms’ wage bill, and property prices. Overall, increasing local tax rates by one to two percentage points does not seem to affect the local economy adversely.

     

The effects of tax policy on financial markets: G3 evidence

We investigate the effects of various tax policy innovations on stock market returns. By using a vector autoregressive model that controls for the mutual causality between fiscal policy and financial market performance, we test whether financial markets serve as a transmission mechanism for tax policy innovations. Our findings indicate that indirect taxes have a larger effect on market returns than do labor taxes. Further, corporate tax innovations do not have any statistically significant effect on stock returns. We consider that this finding is a result of a firm's ability to switch between equity financing and bond financing.     

Married couple work participation and earnings elasticities: evidence from tax data

This paper uses administrative tax panel data to estimate work participation and earnings elasticities of married couples by exploiting variation in tax policy. Not only may individuals alter labor supply by working more or less in response to changes in tax policy, they may also alter reported earnings or shift income between taxable and tax-deferred compensation. As a result, in addition to estimating the standard extensive and intensive labor supply elasticities, we also examine elasticities by type of income (wage earnings vs. self-employment earnings) and compensation (taxable vs. tax-deferred). We find that wives have more elastic work participation and earnings than husbands. Furthermore, self-employment income is more responsive to net-of-tax price changes than wage earnings for both husbands and wives, suggesting that it is easier for the self-employed to alter their work hours, work intensity, and/or reported income than wage earners. Finally, we find that wives respond to changes in the net-of-tax price of earnings by altering the amount of earnings subject to current-year taxes through adjustments of tax-deferred contributions to employer-provided retirement accounts.     

Empirical evidence on the effects of tax incentives

This paper considers two empirical questions about tax incentives: (i)?are incentives used as tools of tax competition and (ii)?how effective are incentives in attracting investment? To answer these, we prepared a new dataset of tax incentives in over 40 Latin American, Caribbean and African countries for the period 1985–2004. Using spatial econometrics techniques for panel data to answer the first question, we find evidence for strategic interaction in tax holidays, in addition to the well-known competition over the corporate income tax (CIT) rate. We find no robust evidence, however, for competition over investment allowances and tax credits. Using dynamic panel data econometrics to answer the second question, we find evidence that lower CIT rates and longer tax holidays are effective in attracting FDI in Latin America and the Caribbean but not in Africa. None of the tax incentives is effective in boosting gross private fixed capital formation.     

Financial leverage and corporate taxation: evidence from German corporate tax return data

To estimate the impact of profit taxation on the financial leverage of corporations, this study uses a pseudopanel constructed from comprehensive corporate tax return microdata for the period 1998–2001, which saw the introduction of major corporate tax reform in Germany. Financial leverage refers to the ratio of long-term debt to total capital. The endogeneity of the firm-specific marginal after-financing corporate income tax rate is controlled for by an instrumental variable approach. The instrument for the observed marginal tax rate is the counterfactual tax rate that a corporation would have faced in a particular period had there been no endogenous change, triggered by the tax reform, of its financial leverage and tax base. This counterfactual tax rate is derived from a detailed microsimulation model of the corporate sector, based on tax return microdata. The marginal tax rate has a statistically significant and relatively large positive effect on corporate leverage; for firms reporting positive profits, an increase of the marginal tax rate of 1 % would increase the financial leverage by approximately 0.7 %, on average. The debt ratio is less responsive to tax incentives for small corporations and firms facing high economic risks.     

The impact of tax enforcement on corporate investment efficiency: evidence from the tax administration information system

Information technology is essential in tax enforcement. This study found that stronger tax enforcement after the tax administration information system reform improved corporate investment efficiency by reducing excessive investment expenditures. The effect is more significant under higher local government fiscal pressure, poorer external information environments, weaker external corporate governance, and stronger tax avoidance motivation. The main mechanism is based on the quality of the accounting information. This study enriches the literature on the economic consequences of tax enforcement and adds investment efficiency as an influential factor, which provides implications for international governments to use information technology to strengthen tax enforcement.

Earnings conservatism: panel data evidence from the European Union and the United States

This paper focuses on earnings conservatism, and provides new evidence based on procedures that account for variability at the firm level, drawing a comparison between the European Union and the United States. A key finding is that the estimated responsiveness of earnings to bad news is substantially higher when unobserved firm-specific effects are modelled. Furthermore, it is shown that accounting has become more conservative not only in the U.S. but also in the EU when taken as a whole, and there is little evidence of marked differences in the asymmetric timeliness of earnings between the two. Indeed, any changes in this property of earnings are likely to be attributable to a common factor that influences firms similarly in both locations, and not necessarily to the process of economic convergence that has taken place in the EU.     

The effects of system design alternatives on the acquisition of tax knowledge from a computerized tax decision aid

Accounting firms are intensifying their reliance on experiential learning, and experience increasingly involves the use of computerized decision aids [Messier, W. (1995) Research in and development of audit decision aids. In R. H. Ashton & A. H. Ashton, Judgment and decision making in accounting and auditing (pp. 207–230). New York: Cambridge University Press]. Accountants are expected to learn from automated decision aid use, because the aids are not always available when dealing with the aid's topical matter, and the knowledge inherent in the aid is needed for competency on broader issues. To facilitate knowledge acquisition and explain the logic of the underlying processes, computerized decision aids provide the rationale for their calculations in the form of online explanations. We study how the location of explanations in a computerized decision aid affects learning from its use. Specifically, this research extends the existing literature by using a framework for the study of learning from decision aid use and by using cognitive load theory to explain the failure of certain decision aid design alternatives to promote learning. We define learning as the acquisition of problem-type schemata, and an experiment is performed in which cognitive load is manipulated by the placement of explanations in a computerized tax decision aid to determine its effect on schema acquisition. Schemata are general knowledge structures used for basic comprehension, and cognitive load refers to the burden placed on working memory when acquiring schemata. We find that increased cognitive load produced by the location of explanations in a decision aid leads to reduced schema acquisition. Our results indicate that when explanations in a computerized decision aid are integrated into its problem solving steps, cognitive load is reduced and users acquire more knowledge from aid use. This appears to be an important design consideration for accounting firms buying or building computerized decision aids.     

Stock selection using a multi-factor model - empirical evidence from the French stock market

Using a Barra-type factor model, we have attempted to determine whether it is possible to beat the benchmark by taking advantage of anomalies established in the financial empirical literature. More specifically we have built an equity premium model based on three sets of factors (accounting variables, stock market characteristics and sector indicators) using a Bayesian method corrected for heteroscedasticity to estimate risk premiums, a technique that takes agents' learning into account. The results are encouraging: first, the factors that carried most weight on the equity premiums corroborated the results of empirical studies described in the financial literature, secondly, the portfolios constructed from our methodology and simulated outside our sample, returned higher performance than the benchmark and rewarded the supplement of volatility.     

Determinants of tax haven utilization: evidence from Australian firms

This paper examines the major determinants of tax haven utilization based on a sample of 200 publicly listed Australian firms, over the 2006–2010 period (1,000 firm‐years). Our regression results show that variables relating to transfer pricing, intangible assets, an interaction term between transfer pricing and intangible assets, withholding taxes, performance‐based management remuneration and multinationality are positively associated with tax haven utilization. We also find that corporate governance structures are negatively associated with tax haven utilization. The magnitude and significance of the regression coefficients indicate that transfer pricing, withholding taxes, intangible assets, an interaction term between transfer pricing and intangible assets, corporate governance and multinationality are the most important drivers of tax haven utilization.     

The effect of tax revenue budgeting errors on fiscal balance: evidence from the Swiss cantons

This study is an empirical analysis of the impact of direct tax revenue budgeting errors on fiscal deficits. Using panel data from 26 Swiss cantons between 1980 and 2002, we estimate a single equation model on the fiscal balance, as well as a simultaneous equation model on revenue and expenditure. We use new data on budgeted and actual tax revenue to show that underestimating tax revenue significantly reduces fiscal deficits. Furthermore, we show that this effect is channeled through decreased expenditure. The effects of over and underestimation turn out to be symmetric.     

The effects of personality traits on digital transformation: Evidence from German tax consulting

Digitization is said to strongly disrupt business and professional life. Especially tax consulting has aroused public interest in this respect. Frey and Osborne (2017) even go so far as to predict that tax consulting will become obsolete. Although these statements are misleading without further interpretation, there is no denying the fact that some change in the accounting and tax profession is inevitable. In Germany, however, business digitization currently does not seem to be urgently necessary in the tax consulting field since this profession is protected by law from competition. Thus, by examining the digitization efforts of German tax consultants we are able to exclude almost all effects of outside pressure and therefore take a look at intrinsic motivation. This study focuses on psychological factors and explores the relationship between tax consultants' Big-Five personality and their level of digitization. Personality is measured using the ten-item Big-Five inventory provided by Rammstedt and John (2007). We develop a digital maturity model based on 20 questions relating to digitization in business and tax consulting. After carrying out a factor analysis, five factors are extracted. To interpret our results, we develop two business model transformation indices as well as an overall digitization index. Our analysis is based on a survey of 968 members of the chamber of tax consultants (Steuerberaterkammer) in Munich, Germany. We are able to show that tax consultants scoring high on extraversion and openness to experience and low on neuroticism exhibit a higher level of digitization. This is, to the best of our knowledge, the first study to discuss intrinsic motivation and digitization in an accounting context. Moreover, an index for digitization as a whole and two business model transformation indices are provided, shedding light upon a hard-to-grasp phenomenon.     

The dynamics of leveraged ETFs returns: a panel data study

Leveraged exchange-traded funds (LETFs) are limited liability securities that allow investors to take daily constant leverage bets on a reference index. This work proposes a new empirical design to investigate the dynamics of quarterly LETFs returns. Rather than relying on fund-by-fund overlapping regressions, as in existing literature, the paper exploits a large panel of non-overlapping data covering the whole universe of Proshares, the US primary LETFs provider. Overall, it is found that the variables prescribed by theory broadly explain cross-sectional variability. It is also found that inverse LETFs and more generally, leveraged funds operating in asset classes like international equity, bonds and commodities underperform theoretical predictions. This underperformance is mainly attributed to frictions in the process of implementing the required daily leverage.     

Size and book to market effects and the Fama French three factor asset pricing model: evidence from the Australian stockmarket

The present study adds to the sparse published Australian literature on the size effect, the book to market (BM) effect and the ability of the Fama French three factor model to account for these effects and to improve on the asset pricing ability of the Capital Asset Pricing Model (CAPM). The present study extends the 1981–1991 period examined by Halliwell, Heaney and Sawicki (1999) a further 10 years to 2000 and addresses several limitations and findings of that research. In contrast to Halliwell, Heaney and Sawicki the current study finds the three factor model provides significantly improved explanatory power over the CAPM, and evidence that the BM factor plays a role in asset pricing.     

The impact of tax on foreign direct investment: Empirical evidence and the implications for tax integration schemes

We estimate the impact of taxation on foreign direct investment (FDI) flows, using data on flows between seven countries for 1984 through 1989, and a sophisticated measure of the cost of capital. We find that the choice between domestic investment and total outward FDI is not significantly affected by taxation but that taxation does affect the location of outward FDI. These results are used to examine the impact of tax integration systems. Giving a tax credit to foreign shareholders may induce a large increase in inward FDI from exemption countries but not from partial-credit countries. For the United States, the total effect would be small.
