A Comparison of Models Describing the Impact of Moral Decision Making on Investment Decisions

Eva Hofmann; Erik Hoelzl; Erich Kirchler

As moral decision making in financial markets incorporates moral considerations into investment decisions, some rational decision theorists argue that moral considerations would introduce inefficiency to investment decisions. However, market demand for socially responsible investment is increasing, suggesting that investment decisions are influenced by both financial and moral considerations. Several models can be applied to explain moral behavior. We test the suitability of (a) multiple attribute utility theory (MAUT), (b) theory of planned behavior, and (c) issue-contingent model of ethical decision making in organizations. In an experimental setting, 141 participants traded company shares in a computerized asset market. Over 12 periods, companies varied in morality (i.e., treatment of employees) and in profitability (i.e., expected dividends per share). Participants’ bids and asks for shares were recorded. Results indicate that moral considerations influence investment decisions, controlling for profit. Differences between the three models are discussed.

'How Can I Help You?' Perceived Service Orientation of Tax Authorities and Tax Compliance

Katharina Gangl; Stephan Muehlbacher; Manon de Groot; Sjoerd Goslinga; Eva Hofmann; Christoph Kogler; Gerrit Antonides; Erich Kirchler

Research on tax behavior has recognized the necessity of changing tax authorities’ approach from enforcement to service orientation. However, empirical investigations of the impact of perceived service orientation on tax compliance are scarce. The present study draws conclusions from survey data of representative samples of 807 Dutch private taxpayers and 1377 entrepreneurs. Perceived service orientation was found strongly related to tax compliance. Furthermore, the link between perceived service orientation and tax compliance is mediated by perceived trustworthiness of authorities. We are confident that taxpayers who perceive a greater service orientation will be more willing to contribute their taxes.

Enhancing Tax Compliance Through Coercive and Legitimate Power of Tax Authorities by Concurrently Diminishing or Facilitating Trust in Tax Authorities

Eva Hofmann; Katharina Gangl; Erich Kirchler; Jennifer Stark

Both coercion, such as strict auditing and the use of fines, and legitimate procedures, such as assistance by tax authorities, are often discussed as means of enhancing tax compliance. However, the psychological mechanisms that determine the effectiveness of each strategy are not clear. Although highly relevant, there is rare empirical literature examining the effects of both strategies applied in combination. It is assumed that coercion decreases implicit trust in tax authorities, leading to the perception of a hostile antagonistic tax climate and enforced tax compliance. Conversely, it is suggested that legitimate power increases reason-based trust in the tax authorities, leading to the perception of a service climate and eventually to voluntary cooperation. The combination of both strategies is assumed to cause greater levels of intended compliance than each strategy alone. We conducted two experimental studies with convenience samples of 261 taxpayers overall. The studies describe tax authorities as having low or high coercive power (e.g., imposing lenient or severe sanctions) and/or low or high legitimate power (e.g., having nontransparent or transparent procedures). Data analyses provide supportive evidence for the assumptions regarding the impact on intended tax compliance. Coercive power did not reduce implicit trust in tax authorities; however, it had an effect on reason-based trust, interaction climate, and intended tax compliance if applied solely. When wielded in combination with legitimate power, it had no effect.

Motivation, values, and work design as drivers of participation in the R open source project for statistical computing

Patrick Mair; Eva Hofmann; Kathrin Gruber; Reinhold Hatzinger; Achim Zeileis; Kurt Hornik

Significance Over the last years, the open-source environment R has become the most popular environment for statistical computing and data analysis across many fields of research. The developer community is highly active: Thousands of packages are available in the official Comprehensive R Archive Network repository and more on developer platforms like GitHub or R-Forge. One question that has not been studied yet is as follows: why do people contribute to the R environment? What are the key motives that drive package authors? Do these developers have specific personal value structures? Are some work environments more conducive to productivity than others? This study is the first empirical study, to our knowledge, performed within the R package author community that finds answers to these questions. One of the cornerstones of the R system for statistical computing is the multitude of packages contributed by numerous package authors. This amount of packages makes an extremely broad range of statistical techniques and other quantitative methods freely available. Thus far, no empirical study has investigated psychological factors that drive authors to participate in the R project. This article presents a study of R package authors, collecting data on different types of participation (number of packages, participation in mailing lists, participation in conferences), three psychological scales (types of motivation, psychological values, and work design characteristics), and various socio-demographic factors. The data are analyzed using item response models and subsequent generalized linear models, showing that the most important determinants for participation are a hybrid form of motivation and the social characteristics of the work design. Other factors are found to have less impact or influence only specific aspects of participation.

Enhancing Tax Compliance Through Coercive and Legitimate Power of Authorities

Eva Hofmann; Katharina Gangl; Erich Kirchler; Jennifer Stark

Strict enforcement and supportive procedures by tax authorities are often discussed as means of enhancing tax compliance. However, it is still not clear how these strategies influence tax compliance. The extended “slippery-slope framework” postulates that coercive power and legitimate power lead to tax compliance, albeit by leading the taxpayer along different motivational paths. The exercising of coercive power reduces citizens’ implicit trust in the authorities and increases the need for enforced compliance and perceptions of an antagonistic climate between tax authorities and taxpayers. Legitimate power is assumed to increase reason-based trust, voluntary cooperation and perceptions of a service climate. Two experimental studies that have manipulated qualities of power either separately or simultaneously have suggested that legitimate power affects intended tax compliance in line with theoretical predictions, whereas the effect of coercive power is less clear.

Power versus trust – what matters more in collaborative consumption?

Eva Hofmann; Barbara Hartl; Elfriede Penz

Purpose Collaborative consumption, such as car sharing, specifically implicates customer-to-customer interaction, which must be regulated by service providers (companies, peers and self-regulating communities), comprising different challenges for business organizations. While in conventional business relations, consumers are protected from undesirable customer behavior by laws, regulations (power) in the context of collaborative consumption are rare, so that trust becomes more relevant. It is the purpose of the study to investigate possible mechanisms to prevent undesirable customers in collaborative consumption. Design/methodology/approach In between subject designs, samples of 186 and 328 consumers filled in experimental online questionnaires with vignettes. Analyses were made of differences among car sharing companies, private persons and car sharing communities in terms of the power of providers, trust in providers and trust in other users of the shared goods, undesirable customer behavior and consumer–provider relations. Findings Companies, private persons and self-regulating communities differ in terms of perceived power and trust. Participants specifically perceive mainly coercive power with the car sharing company, but with the private person and the community, reason-based trust in other users is perceived as prevalent. Nevertheless, undesirable customer behavior varies only marginally over the models. Originality/value The present study is the first to investigate measures to prevent undesirable customer behavior over different collaborative consumption models. This enables appropriate identification of market segments and tailoring of services. The study identifies opportunities for companies in contrast to private persons and self-regulating communities and, in doing so, provides important stimulation for marketing strategy and theory development.

Tax Authorities' Interaction with Taxpayers: Compliance by Power and Trust

Katharina Gangl; Eva Hofmann; Erich Kirchler

According to the Slippery Slope Framework (SSF; Kirchler, Hoelzl, and Wahl, 2008), tax compliance depends on power of tax authorities and trust in tax authorities. The framework, however, remains silent on the dynamics between power and trust and how these affect the interaction climate between authorities and taxpayers. The aim of the present paper is to differentiate between coercive and legitimate power and between reason-based and implicit trust in order to clarify the dynamics between power and trust. Insights into these dynamics may be utilized to change the interaction climate from an antagonistic climate into a service or confidence climate.

Does the sole description of a tax authority affect tax evasion?--the impact of described coercive and legitimate power.

Barbara Hartl; Eva Hofmann; Katharina Gangl; Martina Hartner-Tiefenthaler; Erich Kirchler

Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority’s power. Descriptions of the tax authority’s power may affect taxpayers’ beliefs and as such tax evasion. Experiment 1 investigates the impact of fines and beliefs regarding tax authority’s power on tax evasion. Experiments 2-4 are conducted to examine the effect of varying descriptions about a tax authority’s power on participants’ beliefs and respective tax evasion. It is investigated whether tax evasion is influenced by the description of an authority wielding coercive power (Experiment 2), legitimate power (Experiment 3), and coercive and legitimate power combined (Experiment 4). Further, it is examined whether a contrast of the description of power (low to high power; high to low power) impacts tax evasion (Experiments 2-4). Results show that the amount of fine does not impact tax payments, whereas participants’ beliefs regarding tax authority’s power significantly shape compliance decisions. Descriptions of high coercive power as well as high legitimate power affect beliefs about tax authority’s power and positively impact tax honesty. This effect still holds if both qualities of power are applied simultaneously. The contrast of descriptions has little impact on tax evasion. The current study indicates that descriptions of the tax authority, e.g., in information brochures and media reports, have more influence on beliefs and tax payments than information on fine rates. Methodically, these considerations become particularly important when descriptions or vignettes are used besides objective information.

Authorities' Coercive and Legitimate Power: The Impact on Cognitions Underlying Cooperation

Eva Hofmann; Barbara Hartl; Katharina Gangl; Martina Hartner-Tiefenthaler; Erich Kirchler

The execution of coercive and legitimate power by an authority assures cooperation and prohibits free-riding. While coercive power can be comprised of severe punishment and strict monitoring, legitimate power covers expert, and informative procedures. The perception of these powers wielded by authorities stimulates specific cognitions: trust, relational climates, and motives. With four experiments, the single and combined impact of coercive and legitimate power on these processes and on intended cooperation of n1 = 120, n2 = 130, n3 = 368, and n4 = 102 student participants is investigated within two exemplary contexts (tax contributions, insurance claims). Findings reveal that coercive power increases an antagonistic climate and enforced compliance, whereas legitimate power increases reason-based trust, a service climate, and voluntary cooperation. Unexpectedly, legitimate power is additionally having a negative effect on an antagonistic climate and a positive effect on enforced compliance; these findings lead to a modification of theoretical assumptions. However, solely reason-based trust, but not climate perceptions and motives, mediates the relationship between power and intended cooperation. Implications for theory and practice are discussed.

Coercive and legitimate authority impact tax honesty: evidence from behavioral and ERP experiments

Katharina Gangl; Daniela M. Pfabigan; Claus Lamm; Erich Kirchler; Eva Hofmann

Abstract Cooperation in social systems such as tax honesty is of central importance in our modern societies. However, we know little about cognitive and neural processes driving decisions to evade or pay taxes. This study focuses on the impact of perceived tax authority and examines the mental chronometry mirrored in ERP data allowing a deeper understanding about why humans cooperate in tax systems. We experimentally manipulated coercive and legitimate authority and studied its impact on cooperation and underlying cognitive (experiment 1, 2) and neuronal (experiment 2) processes. Experiment 1 showed that in a condition of coercive authority, tax payments are lower, decisions are faster and participants report more rational reasoning and enforced compliance, however, less voluntary cooperation than in a condition of legitimate authority. Experiment 2 confirmed most results, but did not find a difference in payments or self-reported rational reasoning. Moreover, legitimate authority led to heightened cognitive control (expressed by increased MFN amplitudes) and disrupted attention processing (expressed by decreased P300 amplitudes) compared to coercive authority. To conclude, the neuronal data surprisingly revealed that legitimate authority may led to higher decision conflict and thus to higher cognitive demands in tax decisions than coercive authority.
