This paper uses optimal control theory to derive a desirable trajectory of the number of royalties-paying users of state-owned spectrum for broadcasting. The spectrum royalties are set by the public planner to maximize the consumers’ utilities over an infinite planning horizon. The...

The health-risking informal service is transacted when the expected extra satisfaction rate exceeds the ratio of the expected extra cost to the formal service price. Its prevalence decreases with the costs of risk bearing for the providers and clients. Law-enforcement effort lowers (raises) the...

Utility from consumption might be spoiled by the degradation of the environment. The incorporation of a direct dependency of utility on the state of the environment through environmental concern and the incorporation of the effects of production pollution and rehabilitative investment on the...

An organ transplantation rule is constructed with a special reference to the controversial procedure of transplantation of lung sections from living donors to cystic fibrosis patients. The rule indicates the minimum probability of success required for transplantation and how it is related to a...

A health-risking illegal personal service is transacted when the expected extra satisfaction rate exceeds the ratio of the expected extra cost to the legal service price. Its prevalence decreases with the costs of risk bearing for the providers and clients. Law-enforcement effort lowers (raises)...
