Autonomix, a tool for evaluating measures related to the dependent elderly
Autonomix is a static microsimulation model used for analysing support measures for the care of elderly dependents. It was created by DREES (Directorate for Research, Analysis, Evaluation and Statistics), during the national debate on dependency in 2011. It is primarily backed up by individual data on recipients of the most common aid for dependency of the elderly: the Personalized Autonomy Allowance (Allocation Personnalisée d'Autonomie: APA), which was received in 2013 by 1.2 million individuals in France. The first versions of Autonomix were based on data collected in 2008 from the departments managing the APA. A new version of the model was recently developed following the new data collecting operation in 2012. The model is briefly described in the first part of the article. The analysis of the remaining amount payable by elderly dependents, conducted with Automix, is then presented. Finally, as an illustration, six examples of measures aimed at modifying current public aid provided to these individuals are evaluated using the model. Three measures are related to dependent elderly individuals living in their own homes: the increase in the maximum APA amount, the introduction of resource requirements in order to benefit from APA and the replacement of the current APA co-payment system with an excess system to be adapted based on income. The three other measures cover elderly dependents living in institutions: the systematic attribution of social accommodation benefits without the possibility of recovery, the increase in housing benefits, and the creation of increased housing benefits after a stay of two years.
