Two-sided platforms have a great impact on markets nowadays. Especially, online marketplaces design markets and choose many of the rules that govern how buyers and sellers interact. Researchers studied two-sided platforms very actively over the last two decades. We review the economic literature from two angles: we focus on marketplaces and we concentrate on non-price strategies that marketplaces employ to govern interactions (like user steering, self-preferencing, rating and review systems, data and targeting, privacy, and user protection).
