Positive Invariance of Subset of Positive Externalities

2020 European Control Conference (ECC), 2020
The notion of subset of positive externalities is explored. The subset of positive externalities for games by two pseudo-gradient agents with quadratic payoffs is characterized. It is shown that only a certain subset of the subset of positive externalities can be a positively invariant set of the pseudo-gradient dynamics.

On Positive Externality

2013
This paper fills the gap of modeling positive externality cases when private marginal cost is higher than social marginal cost. Within this unique type of divergence of marginal costs two cases are scrutinized: social marginal benefit being higher than private marginal benefit, and vice versa, social marginal benefit being lower than private marginal ...

Position Auctions with Externalities

2014
This paper presents models for predicted click-through rates in position auctions that take into account the externalities ads shown in other positions may impose on the probability that an ad in a particular position receives a click. We present a general axiomatic methodology for how click probabilities are affected by the qualities of the ads in the

Identification of externally positive systems

2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
We consider identification of externally positive linear discrete-time systems from input/output data. The proposed method is formulated as a semidefinite program, and is guaranteed to identify models that are ellipsoidal cone-invariant and, consequently, externally positive.

The position of the external ear in Turner's syndrome

Clinical Genetics, 1976
The cephalometric roentgenograms of persons with the syndrome of XO gonadal dysgenesis and its variants, and of those with Noonan's syndrome, were compared with a control sample of unaffected females matched for age. Posterior craniofacial relationships differ between XO and normal individuals, particularly in the region of the external auditory meatus,
