Some bidding games converging to their unique pure equilibrium

Benjamin Heymann, Alejandro Jofré

We introduce a class of Bayesian bidding games for which we prove that the set of pure Nash equilibria is a (non-empty) sublattice and we give a sufficient condition for uniqueness…

Optimal auctions for networked markets with externalities

Benjamin Heymann, Alejandro Jofré

Motivated by the problem of market power in electricity markets, we introduced in previous works a mechanism for simplified markets of two agents with linear cost. In standard proc…

On variance reduction for stochastic smooth convex optimization with multiplicative noise

Alejandro Jofré, Philip Thompson

We propose dynamic sampled stochastic approximation (SA) methods for stochastic optimization with a heavy-tailed distribution (with finite 2nd moment). The objective is the sum of…

Incremental constraint projection methods for monotone stochastic variational inequalities

Alfredo Iusem, Alejandro Jofré, Philip Thompson

We consider stochastic variational inequalities with monotone operators defined as the expected value of a random operator. We assume the feasible set is the intersection of a larg…

Extragradient method with variance reduction for stochastic variational inequalities

Alfredo Iusem, Alejandro Jofré, Roberto I. Oliveira +1

We propose an extragradient method with stepsizes bounded away from zero for stochastic variational inequalities requiring only pseudo-monotonicity. We provide convergence and comp…

Solving deterministic and stochastic equilibrium problems via augmented Walrasian

Julio Deride, Alejandro Jofré, Roger J-B Wets

We described a method to solve deterministic and stochastic Walras equilibrium models based on associating with the given problem a bifunction whose maxinf-points turn out to be eq…
