ABSTRACT This paper explores the link between specialization across goods and specialization within goods along the quality dimension. It develops a tractable many-country, many-industry Ricar- dian model with an integer number of heterogeneous firms producing each good, under a generic assumption about the distributions of firm e ciencies. In equilibrium, each country exports a range…

ABSTRACT We analyze the potential trade-off between product variety and consumer information and the implications this trade-off has for product quality. We introduce a simple information accumulation process in a horizontal differentiation model with unobservable quality. As the number of brands increases, per-brand consumer information decreases, which leads to lower average quality. Eventually, the reduction…
