Quality of statistical match and employment simulations used in the estimation of the Levy Institute Measure of Time and Income Poverty (LIMTIP) for South Korea, 2009

The quality of match of the statistical match used in the LIMTIP estimates for South Korea in 2009 is described. The match combines the 2009 Korean Time Use Survey (KTUS 2009) with the 2009 Korean Welfare Panel Study (KWPS 2009). The alignment of the two datasets is examined, after which various aspects of the match quality are described. The match is of high quality, given the nature of the source datasets. The method used to simulate employment response to availability of jobs in the situation in which child-care subsidies are available is described. Comparisons of the donor and recipient groups for each of three stages of hot-deck statistical matching are presented. The resulting distribution of jobs, earnings, usual hours of paid employment, household production hours, and use of child-care services are compared to the distribution in the donor pools. The results do not appear to be anomalous, which is the best that can be said of the results of such a procedure.
