In this paper we study network competition when costs differ among interconnected networks. Such cost differences are observed in the mobile sector as well as in fixed networks. In the paper we find that cost based regulation will not result in first best market shares. The low cost firm will be too small in equilibrium. This is partly due to tariff mediated network externalities. This result i...

In this paper we extend the results of recent studies on the existence of equilibrium in finite dimensional asset markets for both bounded and unbounded economies. We do not assume that the individual’s preferences are complete or transitive. Our existence theorems for asset markets allow for short selling. We shall also show that the equilibrium achieves a constrained core within the same fram...

SFS (Shape From Shading) theory is based upon the Lambertian paradigm. Our visual demonstrations imply that this paradigm fails to apply to the conventional stimuli used to probe vision.

We examine the impacts of resale opportunity on entry and bidding strategies in simultaneous bidding process (auction mechanism) and sequential bidding process (sequential mechanism) with costly entry, and relative performance between the two mechanisms. Resale opportunity reinforces the partial-pooling equilibrium that a bidder submits a jump bid (even higher than his value) to deter following...

background: the aim of this study was to propose a new stochastic model to study the time course of ethanol elimination in human bodies. methods: the times and amount of alcohol ingested are assumed to be random in controllable intervals. constant elimination rate follows zero order kinetics and is replaced by first order kinetics when the effects of alcohol increase due to alcohol ingestion. s...

Abstract One powerful and influential approach to mental representation analyses in terms of biological functions, functions histories natural selection. This “teleosemantic” package, however, faces a familiar challenge. Surely depends only on the present-day structures cognitive systems, not their historical provenance. “Swampman” drives point home. Suppose bolt lightning creates an intrinsic ...

When a person is makes a judgment and assesses confidence, what is the effect of receiving more judgment-relevant information? Following up prior research on belief updating judgments (Oskamp, 1965; Slovic, 1973), we demonstrated that the predictive accuracy of experts did not improve but their confidence climbed steadily as they received more information about the target event. Our findings sh...
