This paper deals with innovative activities of firms, the resulting market success as well as the interdependencies between both. In a first theoretical part, different cases of those interdependencies are investigated by the way of a simple model based on replicator dynamics. It is shown that...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups.Trade induces only firms with high-quality products to export, whereas firms with low-quality products serve only the domestic...
