Source: Data come from the 2008–2016 Turkish Health Surveys which can be accessed through the Turkish Institute of Statistics website (https://www.tuik.gov.tr/Home/Index) with permission.
Note: Columns (1)–(5) report OLS estimates from using the share of Syrian refugee inflows in region population as an explanatory variable. Columns (6)–(10) report IV estimates from instrumenting the share of Syrian refugee inflows in region population by the distance instrument. All specifications control for 26 region and year fixed effects, as well as the individual characteristics, including the child’s age, gender, and indicator variables for the educational attainment of the household head. Columns (2)–(5) and (7)–(10) also control for 26 region-level trade volume, and Columns (3)–(5) and (8)–(10) control for the interaction of the baseline trade volume in 2008 with year dummies. Columns (4)–(5) and (9)–(10) add 12 region-specific linear time trends and 12 region–year fixed effects, respectively. The variables are described in the supplementary online appendix. Standard errors are clustered at the 26-region level. ***, **, and * denote significance at the 1, 5, and 10 percent levels, respectively.

Note: Columns (1)–(5) report OLS estimates from using the share of Syrian refugee inflows in region population as an explanatory variable. Columns (6)–(10) report IV estimates from instrumenting the share of Syrian refugee inflows in region population by the distance instrument. All specifications control for 26 region and year fixed effects, as well as the individual characteristics, including the child’s age, gender, and indicator variables for the educational attainment of the household head. Columns (2)–(5) and (7)–(10) also control for 26 region-level trade volume, and Columns (3)–(5) and (8)–(10) control for the interaction of the baseline trade volume in 2008 with year dummies. Columns (4)–(5) and (9)–(10) add 12 region-specific linear time trends and 12 region–year fixed effects, respectively. The variables are described in the supplementary online appendix. Standard errors are clustered at the 26-region level. ***, **, and * denote significance at the 1, 5, and 10 percent levels, respectively.
