Pensions
The Continuous Sample of Working Lives (CSWL) is a set of anonymized microdata with information about individuals taken from Spanish Social Security records. It provides very valuable information, which is used in many studies on labor economics and in the analysis of the Spanish public pension system as it holds very valuable information about working lives and enables in-depth studies to be made of many aspects of the Spanish pension system that were overlooked before. In this line of research, we focus in the analysis of how representative CSWL is of the population of pensioners for the period 2005-2013. On the other hand we develop a novel methodology based on optimization using mixed integer nonlinear programming for choosing large sub-samples drawn from CSWL that are more representative of the population of pensioners. This methodology is being used to see the advantages of using this sample design procedure in subsequent analysis of the Spanish pension public system.
