Social Accounting Matrix (SAM) Estimation
A major strand of TMD work has been to develop data systems that integrate national, sectoral, and household data in a consistent framework based on a social accounting matrix (SAM). Such data systems support more detailed analysis of the links between macro policies and distributional outcomes, including poverty. Drawing on information theory, we have extended recent work on "maximum entropy econometrics" to develop estimation techniques that use the information we have "efficiently" but do not make any assumptions about information we do not have. The approach we have developed is both powerful and flexible, and we have applied it extensively to estimating SAMs for a large number of countries. In the past year, we have improved the implementation and documentation of these techniques.
