background and objectives: social security organization (sso) is the second largest organization to the ministry of health and medical education (mohme) in providing health care services in iran. in recent years the gap between the sso’s resources and expenditures has shown an unprecedented growing trend due to the rapidly increasing demand. continuation of this trend may lead to financial imba...

The nuclear phase-out and the increased share of renewable distributed generation implicate new challenges for transforming the electric power system into an environmentally sustainable, reliable and cost-efficient system. An important component in transforming the electric power system is the reliable substitution of large controllable power plants by small generation units (photovoltaic syste...

We examine the strategy-proof allocation of multiple resources; an application is the assignment of packages of tasks, workloads, and compensations among the members of an organization. In the domain of multi-dimensional single-peaked preferences, we find that any allocation mechanism obtained by maximizing a separably concave function over a polyhedral extension of the set of Pareto-efficient ...

Crossover designs are well-known to have major advantages when comparing the effects of various non-curative treatments. We compare efficiencies of several crossover designs along with the Balaam’s design with that of a parallel group design pertaining to longitudinal studies where event time can only be measured in discrete time intervals. With equally sized sequences, the parallel group desig...

Information Management and Analysis (IMA) implies the single data and knowledge base of the business organization whose algorithm and software complex is designed to solve functional problems of operating and dispatch management, marketing, financial arrangements, accounting, strategic planning and organizing e-document flow between the sources and users of information. The “information – commu...

A voting scheme assigns to each profile of alternatives chosen by n individuals a compromise alternative. Here the set of alternatives is represented by the Euclidean plane. The individual utilities for the compromise point are equal to the negatives of the distances of this point to the individually best points. These distances are measured by a given strictly convex norm, common to all agents...

Detailed case study material illustrates why the performance of two British national champions (British Airways and British Telecom respectively) was superior to that of their German counterparts (Lufthansa and Deutsche Telekom): beyond just the effects of privatisation, both the airline and telecommunications industries have been characterised by substantial technological and market change whi...

Can subsidies promote Pareto-optimum coordination? We found that partially subsidizing 2 out of 6 players in a laboratory coordination game usually produced better coordination and higher total payoffs both with deterministic and stochastic payoffs. After removing the subsidy, high coordination continued in most groups with stochastic payoffs, but declined for groups with deterministic ones. A ...

We revisit the model of Alós-Ferrer and Weidenholzer (2006) but under the assumption that risk-dominant equilibria are Pareto efficient. It is found that risk-dominant equilibria, non-risk-dominant equilibria and some non-monomorphic states can emerge in the long run when players interact with their immediate neighbors only.
