  • In this article, we show that in models where location is endogenous, maximum welfare losses arising from non-optimal locations or from the lack of market coverage may be substantial. In contrast, maximum welfare losses arising from non-optimal quality choices are more modest, but they might vary discontinuously with the dispersion in consumer tastes. Very often, welfare losses can be inferred from data.
