Social Norms and Conditional Cooperative Taxpayers

This paper incorporates tax morale into the Allingham Sandmo (1972) model of income tax evasion. Tax morale is interpreted as a social norm for tax compliance. The norm strength, depending on the share of evaders in the society, is endogenously derived. Taxpayers act conditionally cooperative, as their evasion decision depends on the other agents' compliance. We characterize an equilibrium which accounts for this interdependence and study the impact of tax and deterrence policies on compliance. Our analysis is then extended to the case of a society which consists of heterogenous communities where individual evasion decisions are embedded in a complex social structure. In this scenario, behavior is crucially influenced by the norm compliance among morale reference groups. Within this framework, we discuss the role of belief management and belief leadership as alternative policy tools

Voting over Taxes: The Case of Tax Evasion

This paper studies majority voting on taxes when tax evasion is possible. We characterize the voting equilibrium where the agent with median taxed income is pivotal. Since the ranking of true incomes does not necessarily correspond to the ranking of taxed incomes, the decisive voter can differ from the median income receiver. In this case, we find unconventional patterns of redistribution, e.g. from the middle class to the poor and the rich. Furthermore, we show that majority voting can lead to an inefficiently low level of taxation – despite a right-skewed income distribution. Hence, the classical over-provision result might turn around, once tax evasion is taken into account

Majority Voting and the Welfare Implications of Tax Avoidance

A benchmark result in the political economy of taxation is that majority voting over a linear income tax schedule will result in an ine±ciently high tax rate whenever the median voter has a below average income. The present paper examines the role of tax avoidance for this welfare assessment. We find that the inefficiency in the voting equilibrium is the lower, the higher the average level of tax avoidance in the economy, or equivalently, the lower the median voter's amount of avoidance. The result holds for endogenous avoidance and labor choice and, under certain conditions, for an endogenous enforcement policy.Tax avoidance, welfare analysis, majority voting, median voter equilibrium

Social Norms and the Evolution of Conditional Cooperation

This paper develops a model of social norms and cooperation in large societies. Within this framework we use an indirect evolutionary approach to study the endogenous formation of preferences and the coevolution of norm compliance. Thereby we link the multiplicity of equilibria, which emerges in the presence of social norms, to the evolutionary analysis: Individuals face situations where many others cooperate as well as situations where a majority free-rides. The evolutionary adaptation to such heterogenous environments will favor conditional cooperators, who condition their pro-social behavior on the others' cooperation. As conditional cooperators react flexibly to their social environment, they dominate free-riders as well as unconditional cooperators

Optimal observability in a linear income tax

We study the optimal observability of the tax base within the standard linear income tax problem, where observability is determined by the government’s investment into the accurate measurement of the tax base. We characterize the optimal level of observability and derive a new expression for the optimal progressivity, which – in addition to the standard equity efficiency trade-off – accounts for the limited accuracy of an income tax system.optimal linear income taxation, observability, tax enforcement

Survey Evidence on Conditional Norm Enforcement

We discuss survey evidence on individuals' willingness to sanction norm violations – such as evading taxes, drunk driving, fare dodging, or skiving off work – by expressing disapproval or social exclusion. Our data suggest that people condition their sanctioning behavior on their belief about the frequency of norm violations. The more commonly a norm violation is believed to occur, the lower the individuals' inclination to punish it. Based on an instrumental variable approach, we demonstrate that this pattern reflects a causal relationship.Norm Enforcement, Sanctioning, Social Norms, Survey Evidence

Deterrence through Word of Mouth

The deterrent effect of law enforcement rests on the link between the actual and the perceived detection risk. We study the role of word of mouth for this linkage. Our approach makes use of micro data on compliance with TV license fees allowing us to distinguish between households who have been subject to enforcement and those who have not. Exploiting local variation in field inspectors’ efforts induced by snowfall, we find a striking response of households to increased enforcement in their vicinity, with compliance rising significantly among those who had no interaction with inspectors. As we can exclude other channels of information transmission, our finding establishes a substantial deterrent effect mediated by word of mouth.deterrence, law enforcement, word of mouth

The Interaction of Legal and Social Norm Enforcement

Although legal sanctions are often non-deterrent, we frequently observe compliance with ‘mild laws’. A possible explanation is that the incentives to comply are shaped not only by legal, but also by social sanctions. This paper employs a novel experimental approach to study the link between legal and social norm enforcement. We analyze whether the two institutions are complements or substitutes. Our results show that legal sanctions partially crowd out social norm enforcement. The welfare effect from mild laws is positive, however, as a higher level of compliance is achieved at lower enforcement costs.social sanctions, legal sanctions, norm enforcement, mild laws, laboratory experiment, VCM, public goods
