Workshop on Mechanism Design requesting Problem Pitches

The fourth Workshop on Mechanism Design for Social Good is taking place this August. 

In addition to requesting papers and demonstrations, they are requesting "problem pitches" where people (say working in policy/NGOs) can submit a problem they have whose solution may involve mechanism design (a subfield of game theory). If accepted, it may interest academics working on these subjects. 

This might be a good opportunity to pitch some problems related to EA. Perhaps related to

1. Donor coordination.
2. Impact prize.
3. Moral trade.

I'm sure that there are many more concrete examples within specific organisations.
