Distribution of costs spent per publication and their EICAT impact level scored. Studies providing higher impacts (MR and MV) cost more money, but studies scoring the lowest impact (MC) cost more on average than those that have medium impact (MN and MO). Cost of the study is ln(USD) purchasing price parity (PPP). Impact scores follow Hawkins et al. 2015: Minimal Concern (MC), Minor (MN), Moderate (MO), Major (MR) and Massive (MV).
