This paper considers a public provider’s strategic use of rationing in a market served by both public and private providers. Such a ‘mixed’ market structure is common in many industries such as health care, telecommunication, postal service, and public utilities. The technology in the private sector exhibits increasing returns: each firm can expend ‘effort’ in the form of fixed cost to reduce t...

This paper studies the impact of vehicle quota system on the market structure of Singapore s car distributorship industry. Using recently available data, we analyzed the populations and new registrations of different brands of passenger car and motorcycle. We found an increase in market concentration in the car distributorship industry, as the market shares of the top distributors have increase...

Considering coalition structures formed by an external licensor of a patented technology and oligopolistic firms, we investigate licensing agreements that can be reached as the bargaining outcomes under those coalition structures. The cores for coalition structures are empty, unless the grand coalition forms. We give the necessary and sufficient condition for the core (for the grand coalition) ...

The paper offers teaching ideas for a technology-enhanced mathematics teacher education course related to an advanced inquiry into one-variable quadratic equations with parameters in place of coefficients. Mathematical activities behind the ideas have been interpreted using the notions of the technology immune/technology enabled (TITE) problem, digital fabrication, collateral learning, and hidd...

I examine loan data from Prosper.com—a website which allows borrowers to post loans and for lenders to bid on those loans. The Prosper market somewhat resembles the theoretical model of search, herding, and crowding in a large market described in Berkovich and Tayon (2009). That model predicts that assets with high and low prices have high variance in the difference between price and true value...

This paper analyzes auctions where budget-constrained bidders have options to declare bankruptcy. It predicts a bidding equilibrium that changes discontinuously in a borrowing rate available to bidders. When the borrowing rate is above a threshold, high-budget bidders win, and the likelihood of bankruptcy is low. When the borrowing rate is below the threshold, the winner is the most budget-cons...

If a monopoly supplies a perishable good, such as tickets to a performance, and is unable to price discriminate within a period, the monopoly may benefit from the potential entry of resellers. If the monopoly attempts to intertemporally price discriminate, the equilibrium in the game among buyers is indeterminate when the resellers are not allowed to enter, and the monopoly’s problem is not wel...

Sustainable disposal of dealuminated metakaolin (DAK) is a crucial environmental issue for the alum production industry. In previous studies, DAK was utilized as eco-friendly cementitious materials, but only 10 wt% used instead cement DAK's high percentage has detrimental effect on mechanical properties, so problem not yet been solved. this study, commercial titanium oxide (TiO2) incorporated i...

Hardness, surface roughness, and adhesion strength were determined for water-based opaque paints applied to heat-treated wood material surfaces. For this purpose, Scotch pine (Pinus sylvestris L.) beech (Fagus orientalis Lipsky) woods used as experimental material. Specimens subjected heat treatment at 3 different temperatures (150, 180, 210 °C) 2 periods (2 4 h) under laboratory conditions. Tw...

We consider a bargaining problem where one of the players, the intellectual property rights owner (IPRO) can allocate licenses for the use of this property among the interested parties (agents). The agents negotiate with him the allocation of licenses and the payments of the licensees to the IPRO. We state …ve axioms and characterize the bargaining solutions which satisfy these axioms. In a sol...
