We study an optimal long-term labor contract that provides disability insurance benefits under two frictions: the agent cannot commit to a long-term contract and the disability shock is private information. We predict that a job with a high risk of disability should provide a higher level of...

We study optimal trading strategy of a market maker with stock inventory in the presence of short-term market changes, especially changes in trading intensity of market participants and stock volatility. We employ Poisson jump processes in modelling such market condition changes. We provide...

In this paper, we suggest a first-passage-time model which can explain default probability and default correlation dynamics under stochastic market environment. We add a Markov regime-switching market condition to a first-passage-time model of Zhou (2001). Using this model, we try to explain...
