August 2017Crime and Violence: Desensitization in Victims to Watching Criminal Events
with Rafael Di Tella, Lucia Freira, Ernesto Schargrodsky, Diego Shalom, Mariano Sigman: w23697
We study desensitization to crime in a lab experiment by showing footage of criminal acts to a group of subjects, some of whom have been previously victimized. We measure biological markers of stress and behavioral indices of cognitive control before and after treated participants watch a series of real, crime-related videos (while the control group watches non-crime-related videos). Not previously victimized participants exposed to the treatment video show significant changes in cortisol level, heart rate, and measures of cognitive control. Instead, previously victimized individuals who are exposed to the treatment video show biological markers and cognitive performance comparable to those measured in individuals exposed to the control video. These results suggest a phenomenon of desensit...
May 2017The Life Cycle of Scholarly Articles across Fields of Research
with Sebastian Galiani: w23447
Aggregate citation behavior plays a key role in scientific knowledge diffusion, as citations document the collective and cumulative nature of knowledge production. Additionally, citations are commonly taken as input for several influential evaluative metrics used to assess researchers’ performance. Nevertheless, little effort has been devoted to understanding and quantifying how article citations evolve over the years following an article’s publication and how these trends vary across fields of research. By collecting and analyzing a dataset consisting of more than five million citations to 59,707 research articles from 12 dissimilar fields of research, we quantify how citations evolve across fields of research as articles grow older. Analyzing raw citation data spanning different periods ...
