Notes: Model 1 is the baseline specification using year dummies. Here |$R_{j}^{y}$| adds interaction terms for the young ages below 25 and |$R_{j}^{o}$| adds interaction terms for ages above 60. All models use dummy variables for the age specification where the omitted category is at age 25. In Model 2 the coefficients for the interaction effects |$\rho _{i}$| are set to zero. Clustered SEs calculated at (i) cohort level (year of birth) and (ii) interval of a years in the age dimension for each year. Conley SEs using a Bartlett Kernel, where t indicates the number of years included in the time dimension and c is the number of cohorts included in the cohort dimension. *, ** and ** indicate statistical significance at the 10%, 5% and 1% levels, respectively.
