Some information on the session logistics:
If not stated otherwise, the discussant is the following speaker, with the first speaker being the discussant of the last paper. The last speaker of each session is the session chair. (Exception: invited sessions)
Presenters should speak for no more than 20 minutes, and discussants should limit their remarks to no more than 5 minutes. The remaining time should be reserved for audience questions and the presenter’s responses. We suggest following these guidelines also in the (less common) 3-paper sessions in a 2-hour slot, to allow participants to move between sessions. Discussants are encouraged to avoid summarizing the paper. By focusing on a few questions and comments, the discussants can help start a broader discussion with the audience.

An RCT to Improve Voluntary Income Tax Compliance in Tanzania VATT Institute for Economic Research, Finland Sub-Saharan African (SSA) countries face limited capacity to enforce tax payments combined with various obstacles that reduce tax compliance. Domestic revenues need to be mobilized to finance growing needs demanded by population growth, rising debt levels and declining development aid, often amidst widespread tax evasion, corruption and weak institutions. This paper examines the scope of fairly inexpensive text message “nudges” to improve voluntary compliance and raise tax revenue in a large and diverse East African economy, Tanzania. Six different behavioural messages were sent monthly to a randomized sample of income taxpayers in December 2023 – June 2024. Results confirmed by extensive robustness checks show little if any effect on taxpayer activity or taxes paid. In the absence of other changes, simple behavioral nudges in the form of text messages appear to have no impact on tax compliance.
