Evidence of the invisible: toward a credibility revolution in the empirical analysis of tax evasion and the informal economy

Empirical research about tax evasion and the informal economy has exploded in the past few decades, seeking to shed light on the magnitude and (especially policy) determinants of these phenomena. Quantitative information informs the analysis of policy choices, enables the testing of hypotheses about determinants of this phenomenon, and can help with the accurate construction of national income accounts. Even as empirical analysis has burgeoned, some have expressed doubts about the quality and usefulness of some prominent measures. The fact that high-quality data is elusive is neither surprising nor a coincidence. The defining characteristic of tax evasion and informal economic activity—that they are generally illegal—often renders unreliable standard data collection methods such as surveys. Unlike invisible phenomena in the natural sciences, these invisible social science phenomena are hard to measure because of choices made by individuals. Analysis of tax evasion and the informal economy must proceed even in the absence of the direct observability of key variables, and theory should guide the construction and interpretation of evidence of the “invisible.” In this paper, we address what can be learned using micro or macro data regarding tax evasion and the informal economy under given conditions and assumptions, and critically review some of the most common empirical methods in light of our conclusions. We conclude with an entreaty for researchers in this field to enlist in the “credibility revolution” (Angrist and Pischke in J. Econ. Perspect. 4(2):3–30, 2010) in applied econometrics.     

Taxes,Theft, and Firm Performance

This paper examines the interaction between income diversion and firm performance. Using unique Russian banking transaction data, I identify 42,483 spacemen, fly‐by‐night firms created specifically for income diversion. Next, I build a direct measure of income diversion for 45,429 companies and show that it is negatively related to firm performance. I identify the main reason for the observed effect as managerial diversion rather than tax evasion per se. I further show that stricter tax enforcement can improve firm performance: a one standard deviation increase in tax enforcement corresponds to an increase in the annual revenue growth rate of 2.6%.     

Determinants of tax evasion: A cross-country investigation

The purpose of this study is to expand on the work of Riahi-Belkaoiu [Riahi-Belkaoiu, A. (2004). Relationship between tax compliance internationally and selected determinants of tax morale. Journal of International Accounting, Auditing and Taxation, 13, 135-143] and systematically investigate, on a cross-country basis, many of the key determinants of tax evasion identified by Jackson and Milliron [Jackson, B. R., & Milliron, V. C. (1986). Tax compliance research: findings, problems and prospects. Journal of Accounting Literature, 5, 125-165]. Based on data for 45 countries, the results of the OLS regression analysis show that non-economic determinants have the strongest impact on tax evasion. Specifically, complexity is the most important determinant of tax evasion. Other important determinants of tax evasion are education, income source, fairness and tax morale. Overall, the regression results indicate that the lower the level of complexity and the higher the level of general education, services income source, fairness and tax morale, the lower is the level of tax evasion across countries. These findings remain robust to a broad range of cross-country control variables, an alternative tax evasion measure and various interactions.     

My journey through finance and stochastics

This year, Finance and Stochastics celebrates its 25th anniversary. The journal provides a platform for the community of researchers on which they can publish their ideas and results.

Publication is an outcome of research which may be conducted for a number of years before it reaches the required maturity. I find this research process to be very important. Unfortunately, it is almost impossible to decode it from reading the research publications. This special issue of Finance and Stochastics gives me an opportunity to focus on it. I am grateful I can present my personal memory of this process. Understanding why questions are asked and how the answers are found is critical.

     

An evasive topic: theorizing about the hidden economy

This paper reviews some central issues that arise in theorizing about tax evasion decisions and the hidden economy. It starts from the Allingham and Sandmo (J. Public Econ. 1:323–338, 1972) modeling of the tax evasion decision as a choice under uncertainty based on expected utility maximization and risk aversion. It goes on to discuss alternative specifications of the taxpayer’s preferences with particular regard to the explanation of the extensive margin, i.e. the decision on whether or not to engage in tax evasion. It extends the model to the case of variable labor supply with work in both official and black labor markets. It then considers the application of the theory to taxes on wealth and income from capital, indirect tax evasion, and smuggling. It also includes a consideration of general equilibrium effects and of the problems that evasion causes for the theory of optimal income and commodity taxes. It concludes with a brief discussion of the implications of tax evasion for economic policy in the welfare state.     

VAT attacks!

Like the theory of the second best that the 2006 congress marks, the value added tax (VAT) is now fifty years old. Judged by the extent and speed of its spread around the world, and the revenue that it raises, the VAT would seem to have been a remarkable success. Over the last few years, however, it has come under a series of attacks. This paper considers three of the most prominent of these. One is the fear (raised mainly in the United States) that the VAT actually does too good a job of raising tax revenue—which raises the empirical question of whether it has indeed proved as effective a source of revenue as its proponents claim and its opponents fear. The second is the view that the VAT does a bad job of taxing the informal sector—and that tariffs might consequently be a better revenue-raising instrument for many developing countries. The third attack is the most literal, by criminals rather than theorists: in the European Union and elsewhere, sophisticated VAT fraud, targeting its refund provisions, has become a serious concern. The paper also argues, more generally, that the many unanswered questions concerning the VAT reflect an unfortunate disconnect between the development of the tax itself and of second best tax analysis. I am grateful to Ben Lockwood and Stephen Smith for allowing me to draw on our joint work, and to Vidar Christiansen, Sijbren Cnossen, Isaias Coelho, Alain Jousten, Victoria Perry, and Emil Sunley for many helpful comments and suggestions. Views and errors remain mine alone, and should not be attributed to the International Monetary Fund.     

Interdisciplinarity and tax law: The case of legal autopoiesis

This paper critically evaluates interdisciplinary research in tax law. The strategy I follow runs at two levels of abstraction.First, I examine a concrete example of interdisciplinary research in taxation. More precisely, I examine Hikaka and Prebble's (2010) recent paper where, applying Luhmannian autopoietic theory to tax law, they make a series of claims about the productivity of their research strategy as well as the consistency and coherence of Luhmann's interdisciplinary framework. Whereas my analytical and conceptual critique of Hikaka and Prebble's paper stands on its own, it should also be read as revealing the obstacles that lurk behind interdisciplinary research in using such a complex and idiosyncratic theory as Luhmann's autopoietic account of law and society. Accordingly, my analysis shows how autopoietic theory can indeed prove useful for tax and accounting reform as well as to connect tax theory and notions of public interest.Second, I extrapolate from the analysis of Hikaka and Prebble's paper some general problems that current interdisciplinary tax research needs to give further consideration: (i) how to identify productive research questions and uses of interdisciplinary resources; (ii) the dubious added value of interdisciplinary research, given its tendency to adopt complex theoretical apparatuses in a cursory way with little comparison being made to existing research achievements; and (iii) the risk of using interdisciplinary research as an exercise of confirmatory investigation and/or an exercise of mere translation of one discipline's problems into another discipline's language.     

What's in a frame? Social organization,risk perception and the sociology of knowledge

A central problem in the sociology of knowledge has been to show that sane people can intelligibly have quite different alternative understandings of the same problem, such as a kind of risk, without abandoning the idea that there is a real problem about which to disagree, and to show the social basis of both plurality and viability. In recent decades, attempts to make this problem tractable have focused on the idea of a ‘frame’. Theories of frames offer accounts of the range of content, as distinguished from theories of processes of diffusion, of which risk amplification theory is the best known example. In this article, several theories of frames – those of Goffman, D'Andrade, Moscovici, Gamson, Schön and Rein, and of prospect theory – found are to be inadequate, because of their lack of clarity and plausibility in their answers to four key questions: ‘what is the relationship between sense‐making and bias?’, ‘how are frames to be individuated?’, ‘where do frames come from?’, and ‘how far and how can people move between frames?’. The article makes the case for a neo‐Durkheimian institutional theory developed by Douglas and others. This approach derives frames as concrete applications to specific contexts from thought styles, which are in turn the product of solidarities or institutional styles of social organization, because it can offer clear, testable, parsimonious hypotheses with which to answer these four questions. The theory therefore provides an account of the institutional logic of framing, and presents reasons for preferring this to non‐institutional approaches such as the various kinds of cognitivism. The article offers three conceptual innovations with which to develop the neo‐Durkheimian theory, in order better to deal with the crucial fourth question about the scope for mobility between frames. These innovations and some specific hypotheses about the scope for mobility between frames are supported by consideration of some exploratory qualitative empirical research on privacy risk perception. The theory provides a more satisfactory strategy for tackling the core problem than most others, by showing plurality to be limited, by showing clear and specific social bases for plurality of frames, by neither wholly endorsing nor wholly rejecting any basic bias, and by showing that their conflictual and systemic interdependence is what makes for viability.     

Financial Accounting Research,Practice, and Financial Accountability

Financial accounting is essential to financial accountability, which is essential to a prosperous society. There are many examples of how improvements to financial accounting, supported by research, have enhanced financial accountability. Such research requires a strong relation between accounting academics and practice; this relation has ebbed and flowed during the life of Abacus. The relation seems to ebb when accounting academics embrace related fields and flows when the relevance to accounting practice emerges. Economics and finance have provided new perspectives and meaningful insights about the information investors need to make informed decisions. Regardless, there are many intriguing and open questions awaiting accounting research that can provide insights into how financial accounting—and thus financial accountability—can be improved. The future is bright for financial accounting researchers who do research relevant to accounting practice and want to contribute to a prosperous society.     

Reporting import tariffs (and other taxes)

This paper derives the implications for compliance and fiscal revenues of a tax base that is the product of several factors. For instance, in the case of import tariffs, the tax base is the product of quantity and unit value, both reported to, and during an audit assessed by, the custom authority. Import tariffs are particularly interesting as custom receipts represent an important share of government revenues in many developing countries and there has recently been a surge in empirical studies showing how evasion in this field is a pervasive phenomenon. I show that, with a multiplicative tax base, when the fiscal authority has an imperfect detection technology a greater declaration in one dimension actually increases the fine when evasion in the other dimension is detected. Therefore, there is an additional incentive for the taxpayer to underdeclare and a multiplicative tax base is subject to more evasion, compared to a tax base that can be assessed directly. As a result, fiscal revenues decrease with the dimensionality of the tax base. Also, voluntary compliance and fiscal revenues may be higher when the importer is required to declare only the total value of imports instead of quantity and unit value separately. This paper provides an argument in favour of uniform or specific tariffs and a reason for why a flat tax may improve compliance.     

A Review of Big Data Research in Accounting

The impending fourth industrial revolution has enhanced the role of big data analytics in today’s business practice. Consequently, many now consider big data as the most strategic resource in business to the extent that organizations that fail to utilize it may become competitively disadvantaged. Following these developments, questions have been raised about the future of the accounting discipline, especially in terms of how it can continue to add value to organizations. While some scholars have attempted to address this question, it remains an abstract concept requiring further investigation. Therefore, this study conducts a systematic literature review to determine the status of accounting research on big data analytics and provides avenues for further studies. By conducting co-occurrence network analysis on 52 peer-reviewed articles published from 2010 to 2020, three broad themes emerged, entailing big data implications for accounting practice, education, and research design. A further examination of the themes revealed few empirical studies on the phenomenon, as conceptual research dominates the field. Although external audit implications of big data are widely discussed, other accounting domains (e.g., managerial accounting and taxation) are underexplored. Therefore, future studies may focus on the implications of big data on variables such as performance measurement, information governance, tax behavior, curriculum design, and pedagogy.     

Evaluation in the Practice of Development

Standard methods of impact evaluation often leave significantgaps between what we know about development effectiveness andwhat we want to know—gaps that stem from distortions inthe market for knowledge. The author discusses how evaluationsmight better address these knowledge gaps and so be more relevantto the needs of practitioners. It is argued that more attentionneeds to be given to identifying policy-relevant questions (includingthe case for intervention), that a broader approach should betaken to the problems of internal validity (including heterogeneityand spillover effects), and that the problems of external validity(including scaling up) merit more attention by researchers.

Corporate tax policy and incorporation in the EU

In Europe, declining corporate tax rates have come along with rising tax-to-GDP ratios. This paper explores to what extent income shifting from the personal to the corporate tax base can explain these diverging developments. We exploit a panel of European data on legal form of business to analyze income shifting via incorporation. The results suggest that the effect is significant and large. It implies that the revenue effects of lower corporate tax rates—possibly induced by tax competition—will partly show up in lower personal tax revenues rather than lower corporate tax revenues. Simulations suggest that between 12% and 21% of corporate tax revenue can be attributed to income shifting. Income shifting is found to have raised the corporate tax-to-GDP ratio by some 0.25% points since the early 1990s. This research was carried out while Ruud de Mooij was a visiting fellow at DG ECFIN in October 2006. The views expressed in this Article are those of the authors and do not necessarily reflect the official position of the European Commission.     

Information Sharing and International Taxation: A Primer

The sharing between national tax authorities of taxpayer-specific information has emerged over the last few years as a—probably ‘the’—central issue on the international tax policy agenda. Yet this refocusing of the debate on international taxation—away from parametric tax coordination and towards strengthening information exchange—has gone largely unnoticed in the public finance literature. This paper gives an overview of this increasingly important area of international taxation, reviewing the key economic, legal, and practical concepts and issues bearing on the analysis and implementation of information exchange, and providing an account of recent policy initiatives and emerging theoretical insights.

Executive pay dispersion,corporate governance,and firm performance

Much of the research on management compensation focuses on the level and structure of executives’ pay. In this study, we examine a compensation element that has not received so far considerable research attention—the dispersion of compensation across managers—and its impact on firm performance. We examine the implications of two theoretical models dealing with pay dispersion—tournament versus equity fairness. Tournament theory stipulates that a large pay dispersion provides strong incentives to highly qualified managers, leading to higher efforts and improved enterprise performance, while arguments for equity fairness suggest that greater pay dispersion increases envy and dysfunctional behavior among team members, adversely affecting performance. Consistent with tournament theory, we find that firm performance, measured by either Tobin’s Q or stock performance, is positively associated with the dispersion of management compensation. We also document that the positive association between firm performance and pay dispersion is stronger in firms with high agency costs related to managerial discretion. Furthermore, effective corporate governance, especially high board independence, strengthens the positive association between firm performance and pay dispersion. Our findings thus add to the compensation literature a potentially important dimension: managerial pay dispersion.

Taking the Long Way Home: U.S. Tax Evasion and Offshore Investments in U.S. Equity and Debt Markets

We empirically investigate one form of illegal investor‐level tax evasion and its effect on foreign portfolio investment. In particular, we examine a form of round‐tripping tax evasion in which U.S. individuals hide funds in entities located in offshore tax havens and then invest those funds in U.S. securities markets. Employing Becker's ( 1968 ) economic theory of crime, we identify the tax evasion component by examining how foreign portfolio investment varies with changes in the incentives to evade and the risks of detection. To our knowledge, this is the first empirical evidence of investor‐level tax evasion affecting cross‐border equity and debt investment.     

Valuation before and after tax in the discrete time, finite state no arbitrage model

We establish necessary and sufficient conditions for a linear taxation system to be neutral—within the multi-period discrete time “no arbitrage” model—in the sense that valuation is invariant to the exact sequence of tax rates, realization dates as well as immune to timing options attempting to twist the time profile of taxable income through wash sale transactions.

“In the study of investments, taxes are largely a source of embarrassment to financial economists.” (Introduction to Dybvig and Ross 1986) “Accordingly, my approach in this chapter is to examine the restrictions on the income measurement rules applicable to financial instruments implied by the requirement that the rules be linear. . . . Linearity is a desideratum of a tidy tax system.” (Bradford 2000, p. 373–374)

     

Political fragmentation and projected tax revenues: evidence from Flemish municipalities

The level of revenues pocketed by a government during the fiscal year often deviates from that projected by this government in its budget. Despite a flourishing literature on, for example, the technical or procedural determinants of such forecast errors, little is yet known about how political stratagems may affect forecast errors. In the present paper, we analyse whether differences in the level of government fragmentation are useful in explaining local government tax revenue forecast errors—controlling for various other factors. Using data on 242 Flemish municipalities for the period 1992–2002, we find that two-party governments are more optimistic than single-party governments. In contrast to our initial expectations, governments with at least three parties are significantly more careful (or less optimistic) in their revenue projections than single- or two-party governments.      

The relationship between culture and tax evasion across countries: Additional evidence and extensions

This study builds on the work of Tsakumis et al. [Tsakumis, G. T., Curatola, A. P,. & Porcano, T. M. (2007). The relation between national cultural dimensions and tax evasion. Journal of International Accounting, Auditing and Taxation, 16, 131-147] by conducting further empirical analysis of the relationship between Hofstede's [Hofstede, G. H. (1980). Cultures consequences: International differences in work-related values. Beverly Hills, CA: Sage Publications] cultural dimensions and tax evasion across countries using multiple measures of tax evasion to gain additional evidence on the subject. Moreover, this study extends the preliminary international tax evasion model developed by Tsakumis et al. [Tsakumis, G. T., Curatola, A. P,. & Porcano, T. M. (2007). The relation between national cultural dimensions and tax evasion. Journal of International Accounting, Auditing and Taxation, 16, 131-147] to examine, along with culture, the impact of legal, political, and religious variables on tax evasion across countries. Based on data from 47 countries, and after controlling for economic development, the regression results indicate that the higher the level of uncertainty avoidance and the lower the level of individualism, legal enforcement, trust in government, and religiosity, the higher is the level of tax evasion across countries. These findings remain robust to multiple measures of tax evasion. Government policymakers should find the results of this study useful in assessing the likelihood of tax evasion from cultural, legal, political, and religious perspectives, and in developing tax reform policies to reduce tax evasion.
