July 2013The Determinants and Consequences of Friendship Composition
with Jason M. Fletcher, Stephen L. Ross: w19215
This paper examines the demographic pattern of friendship links among youth and the impact of those patterns on own educational outcomes using the friendship network data in the Add Health. We develop and estimate a reduced form matching model to predict friendship link formation and identify the parameters based on across-cohort, within school variation in the “supply” of potential friends. Our model provides novel evidence on the impact of small changes in peer demographic composition on the pattern of friendship links. The evidence suggests, for example, that increases in the share of African-American or Hispanic students leads to reductions in the incidence of cross race friendships. We then use the predicted friendship links from the model in an instrumental variable analysis of the...
August 2012Back to the Future? Abortion Before & After Roe
with Theodore J. Joyce, Ruoding Tan: w18338
Next year marks the 40th anniversary of the U.S. Supreme Court decision in Roe v. Wade. We use unique data on abortions performed in New York State from 1971-1975 to analyze the impact of legalized abortion in New York on abortion and birth rates of non-residents. We estimate that abortion rates declined by 12.0 percent for every hundred miles a woman lived from New York in the years before Roe. If Roe were overturned average travel distance to the nearest abortion provider would increase by 157 miles in the 31 states expected to prohibit abortion. Under this scenario abortion rates would fall by 14.9 percent nationally, resulting in at most, 178,800 additional births or 4.2 percent of the U.S. total in 2008. A ban in 17 states would result in a 6.0 percent decline in abortions and at m...
