We examine coordinated effects of mergers in the Swedish retail market for gasoline during the period 1986-2002. Despite significant changes in market concentration and many factors conductive to coordination, the empirical analysis shows that the level of coordination is low. In addition,...

How can we explain the observed behavior of aggregate inflation in response to e.g. monetary policy changes? Mankiw and Reis (2002) have proposed sticky information as an alternative to Calvo sticky prices in order to model the conventional view that i) inflation reacts with delay and gradually...

Prices for, and the affordability of childcare has received increased attention since the advent of the COVID-19 pandemic. In addition, concerns have been raised about potential differences in childcare costs and access between rural and urban communities. To address these issues, we combine...
