Motivated by the recent trend of increasing transparency and traceability in the food and pharmaceutical industries, we investigate the impacts of traceability on a supply chain in which a buyer (e.g., a procurement agent or retailer) sources a product from multiple competing suppliers. When a...

We introduce credit frictions motivated by moral hazard in a general equilibrium model of international trade with two dimensions of heterogeneity and endogenous investments. Firms' competitiveness consists of capabilities to conduct process and quality innovations at low costs, whereas...

We analyze optimal pricing and quality of a monopolistic journal and the optimality of open access in a two-sided model. The predominant aspect of the model that determines the quality levels at which open access is optimal is the nature of the relationship between readers and authors in a...

Using a spatial competition framework with three ex ante identical firms, we study the effects of a horizontal merger on quality, price and welfare. The merging firms always reduce quality. They also increase prices if demand responsiveness to quality is sufficiently low. The non-merging firm,...

We study the effects of horizontal mergers when firms compete on quality and price. Two key factors are identified: (i) the magnitude of variable quality costs, and (ii) the relative magnitudes of cross-quality and cross-price effects on demand. The merging firms will increase (reduce) both...
