We describe firm pricing when consumers follow simple reservation price rules. In stark contrast to other models in the literature, this approach yields price dispersion in pure strategies even when firms have the same marginal costs. At the equilibrium, lower price firms earn higher profits....

Limited consumer attention limits product market competition: prices are stochastically lower the more attention is paid. Ads compete to be the lowest price with other ads from the same sector and they compete for attention with ads from other sectors: equilibrium sector ad shares under free...

According to the celebrated cost recovery theorem, the degree of cost recovery from optimal user charges depends on the extent of scale economies in user costs, infrastructure construction costs and operating costs. This chapter presents the theorem, and reviews various generalisations of it. It...

This chapter summarises the results of the case studies and assesses their main insights. It also draws on recent experience with congestion pricing in London and elsewhere to consider the prospects of successful implementation of efficient pricing and revenue-use schemes.
