Do income tax breaks for the elderly affect economic growth?

Income tax breaks for elderly taxpayers are sizable, widespread, and potentially affect growth through migration and other behaviors. We provide the first investigation into the growth effects of differential tax policy by age, taking a multi-pronged empirical approach to US state-level data since 1977. Some analyses include panel error-correction models combined with variation in state-level policies over time. Alternative analyses use how changes in federal tax law manifest at the state-level. Results suggest that taxes on lower income taxpayers, of any age, decrease growth the most, while taxing the high income elderly—those targeted recently—has little effect.     

Experiential learning through STEM: Recent initiatives in the United States

This paper reviews recent educational initiatives in science, technology, engineering and math (STEM) education in the United States, asking to what extent experiential learning methods are being incorporated into STEM education. We draw on a combination of qualitative and quantitative evidence. The quantitative evidence is from an analysis of the proposal abstracts for all 11,406 of the STEM education and workforce development-related projects funded by NSF grants from the end of 2018 to the beginning of 2022. The qualitative portion of the paper analyzes results from a number of scholarly studies of local initiatives from the last 10 years drawn from a range of published and conference papers, reports and media stories, and project websites, drawn from education research databases, secondary literature, and websites of specific organizations. We seek to classify and describe patterns observed among the projects examined, identifying common patterns and combinations of features. We believe that the paper represents the first comprehensive study of efforts to employ experiential learning methods in STEM education to link formal and informal aspects of learning.     

Fixing feedback revision rules in online markets

Feedback withdrawal mechanisms in online markets aim to facilitate the resolution of conflicts during transactions. Yet, frequently used online feedback withdrawal rules are flawed and may backfire by inviting strategic transaction and feedback behavior. Our laboratory experiment shows how a small change in the design of feedback withdrawal rules, allowing unilateral rather than mutual withdrawal, can both reduce incentives for strategic gaming and improve coordination of expectations. This leads to less trading risk, more cooperation, and higher market efficiency.

Two steps forward,one step back? Quantifying the pecuniary costs of debt account aversion and the debt snowball

The interest-minimizing strategy to paying multiple debts is to make all minimum payments and allocate remaining funds to the debt with the highest interest rate. However, cognitive biases such as debt account aversion and financial advisors encourage borrowers to instead allocate remaining funds to debts with lower outstanding balances, a strategy known as the Debt Snowball. The author uses the 2016 Survey of Consumer Finances to quantify the pecuniary costs for American households of following the Debt Snowball and finds that the average household pays an additional 1.8%–4.3% in interest, leading to an aggregate transfer of wealth from borrowers to lenders of between $46.2 and $53.9 billion in excess of what would occur if borrowers instead minimized interest accrual. Due to differences in household debt structure, the Debt Snowball strategy imposes greater pecuniary penalties on low-income households, on Black households, and on households with more initial debts.
