Do transparency policies work as expected? Evidence from the retail gasoline market
This paper examines how a consumer-side price transparency policy influences spatial competition among firms. For this purpose, I use data from the fuel retail market in the Sydney Metropolitan Area, Australia, where a transparency policy regarding fuel prices was implemented. To understand the implications of the policy on margins, I develop an empirical model of demand and supply. The main feature of the model is that it does not assume all consumers are fully informed, as traditional discrete-choice models do. Instead, it also accomodates consumers with limited information. The transparency policy operates through online information channels of the local government (its website and mobile application), and the data on the usage of these information channels is a key input to the model. Furthermore, by introducing multi-market contact into the model, I allow for heterogeneous coordination among the firms. Counterfactual analysis shows that as consumers become more informed, profit margins decline. |
