New CINCH working paper


A new working paper has been added to the CINCH working paper series: “The Effects of Collecting Income Taxes on Social Security Benefits” by John Bailey Jones and Yue Li.

Since 1983, Social Security benefits have been subject to income taxation, a provision that can significantly increase the marginal income tax rate for older individuals. To assess the impact of this tax, we construct and calibrate a detailed life-cycle model of labor supply, saving, and Social Security claiming. We find that in a long-run stationary environment, replacing the taxation of Social Security benefits with a revenue-equivalent change in the payroll tax would increase labor supply, consumption, and welfare. From an ex-ante perspective an equally desirable reform would be to make the portion of benefits subject to income taxes completely independent of other income.

Is it good to be too light? Birth weight thresholds in hospital reimbursement systems

Birth weight manipulation is common in per-case hospital reimbursement systems, in which hospitals receive more money for otherwise equal newborns with birth weight just below compared to just above specific birth weight thresholds. As hospitals receive more money for cases with weight below the thresholds, having a (reported) weight below a threshold could benefit the newborn. Also, these reimbursement thresholds overlap with diagnostic thresholds that have been shown to affect the quantity and quality of care that newborns receive. Based on the universe of hospital births in Germany from the years 2005–2011, we investigate whether weight below reimbursement relevant thresholds triggers different quantity and quality of care. We find that this is not the case, suggesting that hospitals’ financial incentives with respect to birth weight do not directly impact the care that newborns receive.

New CINCH working paper


A new working paper has been added to the CINCH working paper series: “Fertility Effects of College Education: Evidence from the German Educational Expansion” by Daniel Kamhöfer and Matthias Westphal.

We estimate the effects of college education on female fertility – a so far understudied margin of education, which we instrument by arguably exogenous variation induced through college expansions. While college education reduces the probability of becoming a mother, college-educated mothers have slightly more children than mothers without a college education. Unfolding the effects by the timing of birth reveals a postponement that goes beyond the time in college – indicating a negative early-career effect on fertility. Coupled with higher labor-supply and wage returns for non-mothers as compared to mothers the timing effects moreover suggest that career and family are not fully compatible.
