#1. (A Paper) We consider a paper by Kovandzic, Vieraitis and Boots (2009) entitled "Does the death penalty save lives? New evidence from state panel data, 1977 to 2006" published in Criminology and Public Policy, Volume 8, and Issue 4 from Page 803 to Page 843. The abstract is reproduced verbatim here. Economists have recently reexamined the "capital punishment deters homicide" thesis using modern econometric methods, with most studies reporting robust deterrent effects. The current study revisits this controversial question using annual state panel data from 1977 to 2006. Employing well-known econometric procedures for panel data analysis, our results provide no empirical support for the argument that the existence or application of the death penalty deters prospective offenders from committing homicide. (a) From the above abstract, deduce the following elements: research question, main objective, data, models, and main results. (b) How would you measure the variables "capital punishment" and "homicide deterrence"? (c) What do you think could be the debate behind this study? Explain the different contradictory viewpoints
