Social Connectedness and Information Markets
This paper investigates information quality in a simple model of socially- connected information markets. Suppliers’ payoffs derive from the fraction of consumers who see their stories. Consumers prefer to share and act only on high-quality informa- tion. Quality is endogenous and highest when social connectedness is neither too high nor too low. In highly-connected markets, low-quality stories are widely seen, giving suppliers little incentive to invest in quality. Increasing the volume of misinformation and increasing consumers’ cost of tuning in to suppliers’ broadcasts can each increase equilibrium information quality

The Firm as Tax Shelter: Using Business Resources for Final Consumption
This paper studies tax evasion due to consumption through the firm using a unique matching between administrative monthly micro-data of personal expenditures from an electronic invoice program in Portugal (e-Fatura) with social security registers. Drawing on this unique combination of data, we show that owner-managers shift by about 1/3 of their personal expenditures to firms and by about 1/4 of their household expenditures. The shift is driven by expenditures that lie on the border between business and personal consumption, notably expenditures in retail trade, hotels and restaurants and consultancy services. The use of business resources for final consumption is spread all over the income distribution, but it is particularly concentrated between the 5th-8th deciles. At the top income decile, consumption shifting amounts to 1/5 of household consumption. Back of the envelope computations suggest that the scale of government revenue losses due to consumption shifting amounts to 1% of the GDP.

Distributional Growth Accounting: Education and the Reduction of Global Poverty, 1980-2001.
This article studies the role played by education in the decline of global poverty. In a companion paper, I estimate that the rise of government redistribution in the form of cash transfers, education, healthcare, and other public services accounts for 30% of worldwide poverty reduction since 1980 (Gethin, 2023). In this paper, I incorporate in this analysis the causal impact of schooling on pretax incomes, combining survey microdata covering 95% of the world’s population with a simple model of education and the wage structure. Private returns to schooling account for 50-60% of global economic growth, 60-70% of income gains among the world’s poorest 20% individuals, and 60-90% of the decline in global gender inequality since 1980. Combining direct redistribution and indirect investment benefits from education brings the total contribution of public policies to global poverty reduction to 50-80% or more.
