Over three-quarters of US taxpayers receive income tax refunds, indicating tax prepayments above the level of tax liability. This amounts to a zero interest loan to the government. Previous studies have suggested two main explanations for this behavior: precautionary behavior in light of tax...

This paper studies how the transition from self-employment to employee-jobs over the long run of development explains growth in income tax capacity. I construct a new database which covers 100 household surveys across countries at different income levels and 140 years of historical data within...

This paper estimates the cost of filing taxes and assesses several policy proposals aimed at reducing these costs. Using US tax returns, a quasi-experimental method and additional extrapolations based on survey evidence, I uncover three main findings. First, filing costs are large and have been...

Knowing the elasticity of taxable income (ETI) is crucial for understanding the effects of taxation on taxpayer behavior and consequently on tax revenues. Previous research finds that high-income individuals are the most sensitive to tax policy changes. However, these individuals have more...
