Economists have emphasized the role of dissipative advertising and price as signals of quality. Most works, however, limit the number of types to two options: high and low quality. Yet, production costs and quality both result from Ramp;D efforts and therefore are both uncertain. I characterize...

We provide an explanation for a frequently observed vertical restraint in ecommerce, namely that brand manufacturers partially or completely prohibit that retailers distribute their high-quality products over the internet. Our analysis is based on the assumption that a consumer's purchasing...

We explore whether the global financial crisis has had heterogeneous effects on traded goods differentiated by quality. Combining a dataset of Argentinean firm-level destination-specific wine exports with quality ratings, we show that higher quality exports grew faster before the crisis, but...

This article reviews recent theoretical contributions on digital piracy. It starts by elaborating on the reasons for intellectual property protection, by reporting a few facts about copyright protection, and by examining reasons to become a digital pirate. Next, it provides an exploration of the...

The effects of (private, small-scale) piracy on the pricing behavior of producers of information goods are studied within a unified model of vertical differentiation. Although information goods are assumed to be perfectly differentiated, demands are interdependent because the copying technology...

This paper studies the interactions between the structure of product demand, relative wages, and the allocation of economic activity across two sectors. The agrarian sector produces a homogeneous good and consists of informal firms employing adults and children. The modern sector produces a...

We study a two-sided markets model of two competing television stations that offer content of differentiated quality to ad-averse consumers and advertising space to firms. As all consumers prefer high over low quality content, competition for viewers is vertical. By contrast, competition for...

A standard result in the optimal taxation literature is that, when agents differ in market ability and the government aims at redistributing from high - to low-skilled agents by means of an optimal nonlinear labor income tax and a set of commodity taxes, an optimally designed commodity tax...

We analyse the effect of competition on quality in hospital markets with regulated prices, considering both the effect of (i) introducing competition (monopoly versus competition) and (ii) increasing competition through lower transportation costs (increased substitutability) or a higher number...

We present a heterogeneous-firm model in which management ability increases both pro- duction efficiency and product quality. Combining six micro-datasets on management practices, production and trade in Chinese and American firms, we find broad support for the model's predictions. First, better...
