“…Because we analyze news shocks, that is, future changes in anti-doping policy, the results of our calibrations cannot be directly compared with previous studies that analyzed the perceived values of decision parameters of current anti-doping policy. In particular, our results therefore do not contradict studies advocating for higher fines (e.g., Maennig, 2002) or more sophisticated rank-based sanctioning systems (Berentsen, 2002), differentiation of anti-doping policies across sports (Haugen, 2004), post-testing (Westmattelmann et al, 2014), a more even distribution of prize money (Westmattelmann et al, 2020), or studies emphasizing the role of history and culture, personality factors, and reference group influences (Breivik, 1992;Donovan et al, 2002;and Johnson, 2012). It should be noted that some studies question the effectiveness of improved testing (Haugen, 2004;Strelan and Boeckmann, 2006;Mohan and Hazari, 2016), while we find that news of anticipated improved doping technology reduces doping intensity.…”
