Anderson and Renault (1999) show that when search cost is needed to evaluate any product, a U-shaped relationship exists between equilibrium price and product differentiation. This paper revisits this relationship by incorporating partial-depth search in a sequential search process which allows...

This paper explores how a strategic retailer (e.g., Best Buy) monetizes its showrooming service and its impact on brands' (e-tailers') competition and social welfare. We conduct an equilibrium analysis of duopoly brands in a horizontal market and a vertical market, and compare the results to...

This paper explores the effects of innovation efficiency on technology gap and product diversity between a leading firm and its competitor. Our analysis shows some interesting results: when innovation efficiency is sufficiently large and increases, the leading firm may expand technology gap, and...

Two results are shown about the free-entry equilibrium in a Cournot market with asymmetric firms and imperfectly substituting goods. First, only one technology will survive in the production of each good. Second, some good(s) may not be produced. Specifically, we show that in a two-good model...

This paper develops a framework to study the economic impact of infectious diseases by integrating epidemiological dynamics into a continuous time neo-classical growth model. There is a two way interaction between the economy and the disease: the incidence of the disease affects labor supply and...

Like titanium (Ti) metal, nanotube array films can be grown on Ti alloys by anodization in fluoride containing electrolytes. Further, the anodization of Ti alloys provide a unique pathway to dope TiO2 nanotubes with the alloying element. However, the details of anodization behaviors of Ti alloys...

Graphene is considered as a promising electrode material for supercapacitors due to its large specific surface area, excellent electrical conductivity and so on. In this paper, few-layer graphene is prepared by self-propagating combustion reaction between CO and metal magnesium, using powder MgO...
