We study the influence of minimum quality standards in a two-region partial-equilibrium model of vertical product differentiation and trade. Three alternative standard setting arrangements are considered: Full Harmonization, National Treatment and Mutual Recognition. The analysis integrates the choice of a particular standard setting alternative by governments into the model. We provide a set o...

This report examines the major forms of administration of private health insurance plans. Plans are classified according to whether they are employer-only or joint worker-employer-operated and according to whether they are negotiated or not. A further focus of examination that often reflects industry patterns is whether the plans cover workers of a single employer or involve multi-employer arra...

With the rapid development of the internet, the amount of information and data which are produced, are extremely massive. Hence, client will be confused with huge amount of data, and it is difficult to understand which ones are useful. Data mining can overcome this problem. While data mining is using on cloud computing, it is reducing time of processing, energy usage and costs. As the speed of ...

The notions of deleted and restricted arrangements have been very useful in the study of arrangements of hyperplanes. Let A be an arrangement of hyperplanes and x ∈ A. The deleted and restricted arrangements A and A allows us to compute recursively the Poincaré polynomials of the complement space M(A) with the following formula : Poin(M(A), t) = Poin(M(A′), t) + tPoin(M(A′′), t). In this paper,...

A topological hyperplane is a subspace of R (or a homeomorph of it) that is topologically equivalent to an ordinary straight hyperplane. An arrangement of topological hyperplanes in R is a finite set H such that for any nonvoid intersection Y of topological hyperplanes in H and any H ∈ H that intersects but does not contain Y , the intersection is a topological hyperplane in Y . (We also assume...
