Hi Bluesky!

I'm excited to share my job market paper (for the 2025-26 market)!

It introduces a new extension of RDD where outcomes are entire distributions: Regression Discontinuity Design with Distributions (R3D).

How Much Tax Do US Billionaires Pay? Evidence from Administrative Data Akcan S. Balkir, Emmanuel Saez, Danny Yagan, and Gabriel Zucman NBER Working Paper No. 34170 August 2025 JEL No. H2 ABSTRACT We estimate income and taxes for the wealthiest group of US households by matching Forbes 400 data to the individual, business, estate, and gift tax returns of the corresponding group in 2010- 2020. In our benchmark estimate, the total effective tax rate all taxes paid relative to economic income of the top 0.0002% (approximately the "top 400") averaged 24% in 2018-2020 compared with 30% for the full population and 45% for top labor income earners. This lower total effective tax rate on the wealthiest is substantially driven by low taxable individual income relative to economic income. First, the C-corporations owned by the wealthiest distributed relatively little in dividends, limiting their individual income tax unless they sell their stocks. Second, top-owned passthrough businesses reported negative taxable income on average in spite of positive book income, further limiting their individual income tax. The top-400 effective tax rate fell from 30% in 2010-2017 to 24% in 2018-2020, explained both by a smaller share of business income being taxed and by that income being subject to lower tax rates. Estate and gift taxes contributed relatively little to their effective tax rate. Top-400 decedents paid 0.8% of their wealth in estate tax when married and 7% when single. Annual charitable contributions equalled 0.6% of wealth and 11% of economic income in 2018-20. Akcan S.

Is Mobile Money Changing Rural Africa? Evidence from a Field Experiment Abstract. Rural areas in sub-Saharan Africa are typically underserved by financial services. Mobile money brings a substantial reduction in the transaction costs of remittances. We follow the introduction of mobile money for the first time in rural villages of Mozambique using a randomized field experiment. We find that mobile money increased migration out of these villages, where we observe lower agricultural activity and investment. At the same time, remittances received and welfare of rural households increased, particularly when facing georeferenced village-level floods and household-level idiosyncratic shocks. Our work suggests that mobile money can accelerate urbanization and structural change in sub-Saharan Africa.
