This paper develops an original model of product differentiation, to contribute to the debate about theregulation and finance of public television. It goes beyond the conventional analysis in this topic, byshowing the spill-over effects that a public broadcaster can have upon commercial...

We analyze vertical product differentiation in a model where a good's quality is unobservable to buyers before purchase, a continuum of quality levels is technologically feasible, and minimum quality is supplied under competitive conditions. After purchase the true quality of the good is...

Non-governmental organizations (NGOs) are exerting growing pressure on firms to eliminate product components (such as palm oil) that are harmful to the environment (such as rainforests) or replace such components with NGO-certified sustainable components.
