  2. Mo Moti tivati tion Why Brazil? • A large developing country with a long and dramatic inequality history • High market income inequality (Gini = 0.50-0.60) • Improved data quality and access in recent years The 2000s • Return of growth (18% per adult) amid crises • First “PT” government since early 1960s • Strong decline in income inequality during 2000s according to surveys (‘success story’) : fall in Gini by 7-10 pp Barros et al. (2010) in López-Calva and Lustig (Eds.) Declining inequality in Latin America: A Decade of Progress? 2

  3. Evolution of per adult national income in Brazil: 1985-2015 R$ 40,000 R$ 38,000 R$ 36,000 + 18.2% Constant (2015) Reais R$ 34,000 R$ 32,000 R$ 30,000 - 0.3% R$ 28,000 R$ 26,000 R$ 24,000 1985 1987 1989 1991 1993 1995 1997 1999 2001 2003 2005 2007 2009 2011 2013 2015 Notes: The figure shows the evolution of national income per adult (aged 20+).

  4. Motivation Mo Distributional Na Di National Accounts (DI (DINA NA) = Adding inequality to SNA (using surveys and fiscal data) Applied to Brazil to offer a new analysis of inequality: - How unequal is Brazil? - How has inequality evolved over this new period of growth and government? - Is there evidence of a decline? Sources? - How was growth distributed? First attempt at combining three sources of data for Brazil 4

  6. Da Data Sources Sur Survey eys: PNAD (IBGE) E) § • Micro-files: 2001-2015 • Complemented with POF 2009 survey Pe Pers rsonal income tax declara rations (DIRPF) ) § • Tabulations of total gross income (taxable, withheld & exempt) before social contrib. • Coverage: 25-28 million declarations (20% of adult population) • Tax unit = individuals or couple Na National accounts (I (IBG BGE) § • Flow of funds (2001-2015) = SNA (2008) • Financial balance sheets (2010-2014) 6

  7. Concepts Co Unit of observation: Eq Equal-sp split a t adults ts • Aged 20+, income of married couples is equally divided Income concept: Pr Pre-ta tax post-re replaceme ment t nat national nal i inc ncome me ( (DIN INA) • National income attributed to households • Including pensions + unemployment insurance & deducting social contributions • vs fiscal income = income assessed by tax administration • vs survey income = income appearing in surveys 7

  8. Me Method: building fr from th the e bo bottom up up Na National income + Net government capital + government income Normalize distribution by income + net production taxes (SNA) national income Personal income + Imputed rent (7%) – social contributions (14%) + + non-fiscal income Assume a correlation structure insurance/pension fund between fiscal and missing income (SNA & surveys) income (1%) + household (Gumbel Copula) undistributed profits (6%) Fiscal income = Gross wages + pensions + + top incomes Correct survey incomes by ratio self-employed income + y fiscal / y survey by percentile where it (tax data) capital income ≈ 71% of NI is > 1 Survey income 8

  9. Figure 1. Evolution of total real income in Brazil: 2001-2015 R$ 6,000,000 R$ 5,000,000 R$ 4,000,000 Million (2015) Reais R$ 3,000,000 R$ 2,000,000 National Accounts (national income) National Accounts (fiscal income) R$ 1,000,000 Survey + Tax data (fiscal income) Survey data Tax data R$ 0 2001 2003 2005 2007 2009 2011 2013 2015 Notes: The figure shows the evolution of total real income in billions of Reals across datasets and income concepts. The Survey + Tax data series uses survey incomes up to the percentile where average percentile income in the surveys is less than or equal

  10. Me Method: est stimating th the l e labou our ea earnings d s distr tributi tion on Combine surveys + tax data as above but for labour earnings Note: Labour income is not purely observable in tax returns Estimation: Taxable income (wages, self-employed labour income, rent) Ta § Distribution of taxable income – property rent (= 2% of fiscal taxable § income in national accounts) Assumptions: § • 20% of rental income à Middle 40% taxable income share • 80% of rental income à Top 10% (incl. 40% à Top 1%) share 10

  11. Re Results: : inc income ine inequality quality in in Br Brazil 2001 2001-2015 2015 Extreme and consolidated concentration at the top vs compression in bottom 90% Surveys seem to massively underestimate levels and overestimate decline Overall the distribution narrowed over the period Labour incomes seem to do most of the work . 11
