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.

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.

On the Prevalence of Condorcet's Paradox

Salvatore Barbaro1, Anna-Sophie Kurella2

1Johannes-Gutenberg University Mainz, Germany; 2University of Mannheim, Germany

The Condorcet paradox has been a significant focus of investigation since Kenneth Arrow rediscovered its importance for economic theory. Recent research on this phenomenon has oscillated between simulation studies, probability calculations based on hypothetical voter preferences, and empirical analyses often limited by unsatisfactory data. This paper presents the first comprehensive evaluation of 253 electoral polls conducted across 59 countries. Our findings demonstrate that the Condorcet paradox has virtually no empirical relevance: with only one exception, we find no evidence of cyclical majorities in any of the 253 elections. This result remains robust after statistical inference testing. Furthermore, this study provides insights into which parties are particularly likely to emerge as Condorcet winners and explores how these Condorcet winners assert themselves after elections.

The Impact of the 2021 Expanded Child Tax Credit on U.S. Consumer Sentiment

Jacob E Bastian

rutgers university, United States of America

While consumer sentiment is a key macroeconomic indicator tied to employment and inflation, its response to targeted government policies remains less understood. This study addresses that gap by examining the causal link between fiscal interventions and household confidence, using the 2021 Child Tax Credit (CTC) expansion as a natural experiment. The CTC provided monthly payments that lifted incomes—particularly for lower-income families—until it abruptly expired in early 2022. Drawing on microdata from the University of Michigan’s Consumer Sentiment Survey, we show that removing this crucial support triggered a pronounced drop in economic confidence, most severe among lower-income households and those with multiple children. In contrast, higher-income families saw no substantial change in sentiment. Our findings demonstrate that government policies like the CTC can have significant effects on consumer sentiment, underscoring their vital role for vulnerable populations who rely heavily on such financial support to maintain economic stability.

Tax and Outcomes on Betting: Directing Pro-Poor Policy in Nairobi, Kenya

Beatrice Mbinya1, Kefa Maunda Simiyu2

1University of Cape Town; 2University of Nairobi

This study explored how financial access, tax perceptions, parental behaviors, and gambling activity influenced gambling propensity, intensity, and related financial outcomes, including indebtedness, among low-income individuals in Kenya. Utilizing a cross-sectional Financial Access dataset (2024) by Financial Deepening Sector (FSD), Kenya National Bureau of Statistics, and Central Bank of Kenya, Logistic, Ordered Probit, and Multinomial Logit regressions analyzed these relationships. Findings reveal parental gambling history significantly increased gambling propensity, while mobile money and formal credit access facilitated higher gambling intensity. Crucially, both gambling propensity and intensity significantly heightened "missed," "less," and "late" loan payments, strongly supporting the "no-profitability" hypothesis. Formal credit access emerged as a "double-edged sword," though financial literacy was protective and positive tax perception showed only minor impact. This research contributes granular empirical insights into gambling-to-debt pathways in a low-income Kenyan context. Policy recommendations include progressive gambling taxation and hypothecating revenues for financial literacy and debt counseling programs.

Balancing the Books and Morale: The Impact of Pay Systems and Job Rotation on Worker Turnover

Erika Deserranno1, Julia Salmi2, Miri Stryjan3, Lame Ungwang4

We conduct a randomized experiment comparing individual- and team-based performance pay among credit officers at a microfinance institution in Uganda. We find that tying rewards to individual or team performance has no significant effect on job performance (loan outcomes). However, turnover is substantially higher under individual incentives, with twice as many employees leaving compared to the team-based scheme. Survey data also reveals lower job and workplace satisfaction under individual incentives. Importantly, when individual incentives are combined with a portfolio rotation policy — which more equitably distributes opportunities for bonuses — the negative effect on turnover is mitigated. These results highlight the risks of individual incentive pay, which can reduce satisfaction and increase turnover. Introducing complementary policies like portfolio rotation can help address these unintended consequences and support better retention under individual-based incentive systems.
