1. Do Children of Immigrant Parents Assimilate into Public Health Insurance? A Dynamic Analysis by Julie Hudson Yuriy Pylypchuk August 10, 2009

2. Background Insurance status among children with native parents (2005) Insurance status among children with native parents (2005) – 67% private – 28% public – 4% uninsured Insurance status among children with at least one foreign born parent (2005) Insurance status among children with at least one foreign born parent (2005) – 48% private – 40% public – 12% uninsured

3. Background Children of immigrant parents are more likely to participate in public coverage than natives by 12 percentage points Children of immigrant parents are more likely to participate in public coverage than natives by 12 percentage points – consistent with immigrant participation in other public programs (AFDC, Food Stamps) Public issue Public issue – Cost implications for Medicaid and SCHIP – Lack of coverage prevents access to care among children => future burden?

4. Key Issue Does a child’s participation in public coverage depend on his/her parent’s stay in the U.S? Does a child’s participation in public coverage depend on his/her parent’s stay in the U.S? – The propensity to participate can increase, decrease, or remain the same with parents length of stay in the U.S. – If decreases => children of immigrant parents assimilate out of public coverage – If increases => children of immigrant parents exhibit increasing welfare dependence (found among adults for AFDC/TANF)

5. Study Objectives Does a parent’s length of stay in the U.S affect eligible children’s propensities to Does a parent’s length of stay in the U.S affect eligible children’s propensities to – Enter into public coverage – Retain public coverage Are there differential effects of immigration- citizenship status of Mothers versus Fathers? Are there differential effects of immigration- citizenship status of Mothers versus Fathers? What is the role of a child’s own immigration- citizenship status for entry/retention? What is the role of a child’s own immigration- citizenship status for entry/retention? How do immigration characteristics affect a child’s participation in public coverage in the steady state How do immigration characteristics affect a child’s participation in public coverage in the steady state

Ham et al., 2008. – Transitions among private, pubic, and no insurance. No immigrants characteristics in the model. Hispanics are more likely to enter public coverage

7.

8. Data Information about immigrants is extracted from National Health Interview Survey Information about immigrants is extracted from National Health Interview Survey In all models we control for In all models we control for – State quarterly unemployment rate – Cohort effects – Parent education and health status – Children’s health status, region and MSA, race and age All models are estimated separately for two and one parent households All models are estimated separately for two and one parent households

9. Model Hazard of entering public coverage Hazard of entering public coverage M - years of stay in the U.S M - years of stay in the U.S Hazard of retaining public coverage Hazard of retaining public coverage – Do not control for initial conditions – Do not control for unobserved heterogeneity

Steady state Let R be 2X2 transition matrix, where the element of the matrix, represents the predicted probability of moving from state k to state j Let R be 2X2 transition matrix, where the element of the matrix, represents the predicted probability of moving from state k to state j Let P denote the row vector of participating in public coverage or having other insurance status in steady state Let P denote the row vector of participating in public coverage or having other insurance status in steady state To find element in matrix P, solve To find element in matrix P, solve The effect of the binary covariate, X, on steady-state probability is simply The effect of the binary covariate, X, on steady-state probability is simply The expression informs us of the long run effects of a specific covariate on the likelihood of being in public coverage The expression informs us of the long run effects of a specific covariate on the likelihood of being in public coverage

19. Conclusions and Policy Implications Overall, participation rates among children of immigrant and native born parents are very similar Overall, participation rates among children of immigrant and native born parents are very similar Differences depend on household structure and nativity status of a mother or father Differences depend on household structure and nativity status of a mother or father – Hazard of Entry into public coverage decreases for children with citizen immigrant father decreases for children with citizen immigrant father increases for children with non-citizen immigrant mother increases for children with non-citizen immigrant mother – Hazard of Retaining public coverage Does not depend on the nativity status of child’s father Does not depend on the nativity status of child’s father Decreases for children with non-citizen immigrant mother Decreases for children with non-citizen immigrant mother For one parent households, children with a foreign born parent exhibit assimilation out of public coverage For one parent households, children with a foreign born parent exhibit assimilation out of public coverage

20. Conclusions and Policy Implications Higher parental education and being an immigrant child affect entry into and retention of public coverage Higher parental education and being an immigrant child affect entry into and retention of public coverage – Education – attitudes to public porgrams and/or job opportunities? – Foreign born child - Chilling effect? – Overall, results are robust to alternative specifications No evidence of assimilation into public coverage among children with foreign born parents No evidence of assimilation into public coverage among children with foreign born parents – Contrary to the literature on adult immigrants’ participation in welfare programs
