Professional economists rarely write on questions of genocide. This surprises because a workhorse tool of the economics discipline concerns the analysis of behavior that takes place under constraints. All parties in genocide—perpetrators, victims, and third parties—face cost and resource...

In this working paper we go on with the study of a mapping in Rn associated to a quadratic optimization problem with one equality linear constraint. After showing some general properties related to homogeneity and the inverse mapping, we present some results regarding how the mapping behaves...

This paper presents a method capable of estimating richly parametrized versions of the dynamic conditional correlation (DCC) model that go beyond the standard scalar case. The algorithm is based on the maximization of a Gaussian quasi-likelihood using a Bregman-proximal trust-region method to...

The paper identifies a necessary and sufficient condition for a deterministic local optimum to be locally improved upon by a stochastic deviation. When this condition is satisfied, a method to construct the stochastic allocations that increase the objective is provided. This technique is applied...
