Non-compliance of firms with tax regulations is a major constraint on state capacity in developing countries. We focus on an arguably under-appreciated dimension of non-compliance: under-reporting of wages by formal firms to evade payroll taxes. We develop a simple partial-equilibrium model of...

Standard economic models of tax compliance have focused on enforcement-driven compliance. Notably, tax administrators also tend to place a great deal of emphasis on the importance of improving "tax morale" by encouraging voluntary compliance, creating a culture of compliance, and changing social...

This paper studies the impact of "nudges" on taxpayers with varying tax compliance histories in Papua New Guinea. We present the results from two population-wide randomized controlled trials in a setting that is characterized by low compliance rates and a lack of effective enforcement. We test...

This paper presents the findings of two Randomized Controlled Trials (RCTs) that were conducted in collaboration with the Australian Taxation Office (ATO). The first trial tests the effect of changes to letters (timing, social norms, color, and provision of information about charitable...

We present the first randomized survey experiment in the context of tax compliance to assess the role of social norms and reciprocity for intrinsic tax morale. We find that participants in a social-norm treatment have lower tax morale relative to a control group while participants in a...

Many defined-benefit pension systems in developed and developing countries use a small set of final years of earnings to compute pension benefits. This provides dynamic incentives to report higher earnings in the final years of the career. In this paper, we document the responses of...

We study the impact of media bias on tax compliance. Through a framed laboratory experiment, we assess how the exposure to biased news about government action affects compliance in a repeated taxation game. Subjects treated with positive news are significantly more compliant than the control...

This paper provides theoretical and empirical evidence on the implications of the timing of reminders by studying the effect of varying the timing of reminder letters to taxpayers on their payment behavior. The collection of unpaid tax debts constitutes a considerable challenge for tax...

We develop a framework to analyze partial population experiments, a generalization of the cluster experimental design where clusters are assigned to different treatment intensities. Our framework allows for heterogeneity in cluster sizes and outcome distributions. We study the large-sample...
