We review the advances in mathematical formulation of continuous-time principle-agent problem in the recent decade and provide a template for writing agency problems in a rigorous fashion. We present ... More

In stochastic control applications, typically only an ideal model (controlled transition kernel) is

assumed and the control design is based on the given model, raising the problem of performanc... More

We derive the short-maturity asymptotics for VIX option prices in local-stochastic volatility models. Both out-of-the-money (OTM) and at-the-money (ATM) asymptotics are considered. Using large deviati... More
