Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Paper Description
Previous studies of the impact of changes in prison populations on crime rates have failed to control adequately for the simultaneity between those two variables. While increases in the number of prisoners are likely to reduce crime rising crime rates also translate into larger prison populations. To break that simultaneity this paper uses the status of prison overcrowding litigation in a state as an instrument for changes in the prison population. Overcrowding litigation is shown to have a negative impact on prison populations but is unlikely to be related to fluctuations in the crime rate except through its effect on prison populations. This methodology results in estimates of the elasticity of crime with respect to the numbers of prisoners that are two to three times greater than those of previous studies. The results are robust across all of the crime categories I examine. For each prisoner reduction induced by overcrowding litigation the total number of crimes committed increases by approximately 15 per year. The social benefit from eliminating those 15 crimes is approximately $45000; the annual per-prisoner costs of incarceration are roughly $30000.
