Working Papers
"Can growth heal the political divide?" with Dimitrios Xefteris. Working paper, March 2024.
We measure political polarization by the cost that agents are willing to incur to advance their ideas, and we relate it to economic growth.
"Efficiency in collective decision-making via quadratic transfers", with N. Immorlica, S. Lalley, K. Ligett, G. Weyl and D. Xefteris. ArXiv 2301.06206 working paper, January 2023.
In a collective choice problem with multiple alternatives, a mechanism with quadratic transfers implements the utilitarian optimum. An earlier version with complete information here.
"Voter polarization and extremism", with Tai-Wei Hu. Michigan State U. Dept Economics w.p. No 2022-5, October 2022.
Voters who face costs of processing information optimally ignore small signals, and as a result, they end up polarized into extreme positions.
"Lognormal (re)distribution: A macrofounded theory of inequality", with Dimitrios Xefteris. No. 04-2022. U. of Cyprus Dept. of Economics w.p. 04-2022, May 2022.
Policy-makers choose policies that induce a lognormal distribution of income that is optimal for an agent richer than the median voter.
'k-proper equilibria', with A. Nicolò. SSRN wp 2531741, 2014. Latest version: September 2020.
