Public health insurance and other arrangements covering health costs effectively provide insurance against changes in health status. These arrangements engage in burdensmoothing over the life cycle and entail various elements of redistribution. Lack of portability regarding this type of cover may impede international mobility and create financial losses or windfall gains on various sides, which…

We investigate optimal taxation of lifetime income with and without an option to emigrate during old age. The government sets the rates of deferred taxation and of taxes on interest income. With immobile agents, the optimal policy consists of full deferral of income taxes on savings and full taxation of interest. Potential mobility of the old calls for lower degrees of deferral and reduced taxa…

This article proposes a notional defined contribution (NDC) mechanism to ensure pension mobility for the 150 million migrating workers in China during both the accumulation and drawdown phases. Planned governance would ensure independence from the three existing pension systems. An appropriately structured NDC plan of this type is shown to be viable by reference to a previously developed model …

Let k be an arbitrary field and Q be an acyclic quiver of tame type (that is, of type˜ An, ˜Dn, ˜E6, ˜E7, ˜E8). Consider the path algebra kQ, the category of finite-dimensional right modules mod-kQ, and the minimal positive imaginary root of Q, denoted by δ. In the first part of the paper, we deduce that the Gabriel–Roiter (GR) inclusions in preprojective indecomposables and homoge…

We provide a condition for systolic complexes implying hyperbolicity, which is weaker than 7-systolicity.

We present a new approach to an equivariant version of Farber’s topological complexity called invariant topological complexity. It seems that the presented approach is more adequate for the analysis of impact of a symmetry on a motion planning algorithm than the one introduced and studied by Colman and Grant. We show many bounds for the invariant topological complexity comparing it with a…
