Elections define representative democracies, but also produce spikes in physical mobility if voters need to travel to electoral rooms. In this paper, we examine whether large-scale, in-person elections propagate the spread of COVID-19. We exploit a natural experiment from the Czech Republic...

Building on the work of Nash, Harsanyi, and Shapley, we define a cooperative solution for strategic games that takes account of both the competitive and the cooperative aspects of such games. We prove existence in the general (NTU) case and uniqueness in the TU case. Our main result is an...

Every simple monotonic game in bv'NA is a weighted majority game. Every game v[set membership, variant]bv'NA has a representation where u[set membership, variant]pNA, [mu]i[set membership, variant]NA1 and fi is a sequence of bv' functions with . Moreover, the representation is unique if we...
