Working Papers

Wealth, Returns, and Taxation: A Tale of Two Dependencies, with Philipp Wangner (TSE), August 2022. [online appendix, NBER slides, SSRN]

  • In short: We study wealth redistribution when individual portfolio choices and associated returns are correlated with wealth through: (i) type dependence, i.e. investment skills drive return differences and (ii) scale dependence, i.e. wealth itself triggers returns. Four key statistics characterize the macro and welfare implications of wealth taxation: the right tail of the wealth distribution, the degree of scale and type dependence, and the extent to which returns reflect investment productivity.

Value Added and Productivity Linkages Across Countries, with François de Soyres (FRB), August 2021, R&R at AEJ: Macro. [online appendix, slides, voxEU]

  • In short: IRBC models produce a weak relationship between trade and cross-country real GDP correlations, contradicting widespread empirical findings. We solve this puzzle by showing that whenever imported input’s base period price does not reflect their marginal revenue product real GDP movements become mechanically linked to fluctuations in imported inputs.

Gross Labor Market Flows, Self-Employment, and Unemployment Insurance, with Sumudu Kankanamge (TSE), July 2022. [online appendix]

  • In short: We document that the selection into self-employment is highly responsive to variations in unemployment insurance (UI) generosity. We develop an occupational choice model of employment, unemployment, and self-employment and show that changes in the relative riskiness between occupations is key to understand this high responsiveness.

Buying and Selling Entrepreneurial Assets, with Sumudu Kankanamge (TSE), June 2020.

  • TSE Working paper. An old version with application on the aging of entrepreneurs: SED 2019 Meeting, Slides.
  • In short: How are the options to buy and sell a business relevant for entrepreneurs? We introduce a theory of entrepreneurial assets transfer consistent with empirical evidence and quantify the importance of the market for businesses in the US.


Publications

Global Trade and GDP Comovement, with François de Soyres (FRB), May 2022, Journal of Economic Dynamics and Control. [WP version]

  • In short: This paper provides new empirical findings regarding the relationship between trade and cross-country GDP correlation using a large sample of countries. We introduce two notions of trade linkages: (i) direct bilateral trade index and (ii) common exposure to "third" countries capturing the role of trade networks.
