Resource Extraction from a Stochastic Population with Harvesting Quotas

Erik Ekström, Dante Mata, Harto Saarinen

We study a resource extraction problem of ergodic type, where harvesting quotas are imposed that restrict the harvesting rate by a function of the current biomass. In a setting wit…

Hiring and firing -- a signaling game

Erik Ekström, Topias Tolonen-Weckström

We study a signaling game between an employer and a potential employee, where the employee has private information regarding their production capacity. At the initial stage, the em…

Stopping problems with an unknown state

Erik Ekström, Yuqiong Wang

We extend the classical setting of an optimal stopping problem under full information to include for problems with an unknown state. The framework allows the unknown state to influ…

The maximality principle in singular control with absorption and its applications to the dividend problem

Tiziano De Angelis, Erik Ekström, Marcus Olofsson

Motivated by a new formulation of the classical dividend problem, we show that Peskir's maximality principle can be transferred to singular stochastic control problems with 2-dimen…

A sequential estimation problem with control and discretionary stopping

Erik Ekström, Ioannis Karatzas

We show that "full-bang" control is optimal in a problem that combines features of (i) sequential least-squares {\it estimation} with Bayesian updating, for a random quantity obser…

Bayesian sequential composite hypothesis testing in discrete time

Erik Ekström, Yuqiong Wang

We study the sequential testing problem of two alternative hypotheses regarding an unknown parameter in an exponential family when observations are costly. In a Bayesian setting, t…
