abstract = {We show that for a spatially differentiated economy reduced product variety is the likely
outcome of mergers except in cases where exit costs in relation to (outlet-specific) fixed costs
are high. Our empirical analysis of the Austrian retail gasoline market confirms that increases
in concentration reduce product variety. Ignoring this product variety effect is likely to lead to
an underestimate of market power in structural merger analysis.},
