Online Appendix of “Child Adoption Matching: Preferences for Gender and Race”

In Appendix A, we provide some additional analysis and robustness checks to support the results in the paper. In Appendix B, we detail the PAPs’ preferences with respect to the time at which a baby is presented on the website, and we find that the desirability of a baby is monotonically increasing during the pregnancy, and decreases rapidly after birth. Finally, in Appendix C, we present an example of a basic model of matching with search frictions that is consistent with our empirical strategy. Appendix A: Supplementary Analysis Variable Mean Std.
