This paper analytically examines the demand for surgical masks following the recent health precautions due to coronavirus. Using a simple linear demand curve and alternatively examining the impacts of requirements that mandate (a) the wearing of masks by frontline workers; (b) suggested but not...

Airports have become platforms that derive revenues from both aeronautical and commercial activities. The demand for these services is characterized by a one-way complementarity in that only air travelers can purchase retail goods at the airport terminals. We analyze a model of optimal airport...

Empirical studies show that tradable consumption goods are more expensive in rich countries. This paper proposes a simple yet novel explanation for this apparent failure of the law of one price: Consumers' utility from tradable goods depends on their consumption of complementary goods and...

This note considers the degree of complementarity of non-aviation activities to airside activities at airports in relation to airport governance and regulation. A simple economic model of airport operations is employed to draw the distinction between complementary and non-complementary...

This paper develops a model to understand mechanisms behind the rise of mass consumption societies. The development process depicted in the model follows the Flying Geese pattern, in which a series of industries takes off one after another. As productivity improves in these industries, each...

The Bulow et al. [1985] framework is explored assuming demand and/or production relations. A multiproduct firm is assumed to have a single product rival in one of the two submarkets in which it participates. In the case of linear demand and cost functions, the direct and the strategic effects of...
