Reconciling Household Surveys and National Accounts Data Using a Cross Entropy Estimation Method

Abstract

This paper presents an approach to reconciling household surveys and national accounts data. The problem is how to use the information provided by the national accounts data to re-estimate the household weights used in the survey so that the survey results are consistent with the aggregate data. The estimation approach uses an estimation criterion based on an entropy measure of information. The survey household weights are treated as a prior. New weights are estimated that are close to the prior and that are also consistent with the additional information. This approach is implemented to reconcile household survey data and macro data for Madagascar. The results indicate that the approach is powerful and flexible, supporting the efficient use of information from a variety of sources to reconcile data at different levels of aggregation in a consistent framework.

Micro-econometric and Micro-Macro Linked Models: Sequential Macro-Micro Modelling with Behavioral Microsimulations

“…While the macro models rely on consistent theoretical frameworks, the reduced-form models underlying the micro-simulation do not fulfill the requirements, for example in terms of functional forms. Furthermore, empirical inconsistency between national accounts and household survey data that becomes apparent in macro-micro applications is known to be notorious (Round 2003;Robilliard and Robinson 2003).…”

Simulating the Impact on the Local Economy of Alternative Management Scenarios for Natural Areas

“…The cross entropy method estimates a balanced and consistent matrix starting from an original unbalanced social accounting matrix using information available both at micro and macroeconomic levels (Robilliard andRobinson, 1999 andRobinson et al, 1998). …”

“…An analytic description of the complete model, where row and column sums involve errors in measurement, is presented in Robilliard and Robinson (1999) and Robinson and El-Said (2000). The balanced SAM for the High Garda Natural Park is reported in Table 3.…”

Labour supply and income distribution effects of the working income tax benefit: a general equilibrium microsimulation analysis

“…To keep the structure of the economy unchanged, we adjust household data to meet the national accounts totals. To adjust households' consumption and income components, we minimise the cross entropy divergence measured by the Kullbak-Leibler function, as in Robilliard and Robinson (2003), subject to the constraint of equality between the SAM cells and the total weighted household observations values. Other minimisation criteria, such as the standard sum of squared differences, were also tested and compared, but did not perform better.…”
