mechanism design/market design is a huge part of CS that overlaps with economics. Also I am not sure how much the article emphasized this but a big part of the success of these programs is designing 'good' matchings which is computationally tricky and also requires a bunch of domain expertise. actually implementing this and understanding the complexity limitations/what type of ILP (integer linear program)/ fault tolerance etc etc... is a triumph of computer science (also econ!)
