Description

This paper develops a novel methodology to combine administrative records and household surveys using Optimal Transport. This allows us to preserve all information from individual tax records, bringing in informal income and capturing the real size of households (as reported in surveys) while preserving official marriage and filial relationships. The preliminary results are different from those obtained using only surveys as the main source of income information and this method will provide the basis to measure Household Distributional Accounts for Chile in the future.
