Strategic choice of price-setting algorithms
Buchali, Katrin; Grüb, Jens; Muijs, Matthias; … - 2023
Recent experimental simulations have shown that autonomous pricing algorithms are able to learn collusive behavior and thus charge supra-competitive prices without being explicitly programmed to do so. These simulations assume, however, that both firms employ the identical price-setting...

Market transparency and consumer search - evidence from the German retail gasoline market
Martin, Simon - 2020
We study a novel trade-off in market transparency regulation by estimating a structural model of the German retail gasoline market. Transparent environments enable easy price comparisons and match findings. Restricting transparency such that only the cheapest offers are shown induces firms to...
