In this note we prove the σ-compactness of a set of probability measures with finite expectation, defined on metric spaces. Our result is motivated by the problem of the existence of measurable selectors for multifunctions in decision problems where the action space is a set of probability...

Let ℓ be Lebesgue measure and X=(Xt,t≥0;Pμ) be a supercritical, super-stable process corresponding to the operator −(−Δ)α/2u+βu−ηu2 on Rd with constants β,η0 and α∈(0,2]. Put Wˆt(θ)=e(|θ|α−β)tXt(e−iθ⋅), which for each smallθ is an a.s. convergent complex-valued...

In this paper, we discuss the Expected Residual Minimization (ERM) method, which is to minimize the expected residue of some merit function for box constrained stochastic variational inequality problems (BSVIPs). This method provides a deterministic model, which formulates BSVIPs as an...

We provide new methods for inference in econometric models where the parameter of interest is a set. These models arise in many situations where point identification requires strong (and sometimes untestable) assumptions. Every parameter vector in the set of interest represents a feasible...

Examples with zero-sum linear differential games of fixed terminal time and a convex terminal payoff function depending on two components of the phase vector are considered. Such games can have an indifferent zone with constant value function. The level set of the value function associated with...

We prove a functional central limit theorem for the Hausdorff measure of level sets generated by a smooth Gaussian random field.
