optimal credit portfolio and consumption with regime switching and default contagion
Fei Sun, Wenyuan Wang, Kaixin Yan
We study optimal portfolio and consumption in a regime-switching multi-name credit market with default contagion. Defaults generate portfolio losses and alter the intensities of su…
Optimal portfolio under ratio-type periodic evaluation in stochastic factor models under convex trading constraints
Wenyuan Wang, Kaixin Yan, Xiang Yu
This paper studies a type of periodic utility maximization problem for portfolio management in incomplete stochastic factor models with convex trading constraints. The portfolio pe…
De Finetti's problem with fixed transaction costs and regime switching
Wenyuan Wang, Zuo Quan Xu, Kazutoshi Yamazaki +2
In this paper, we examine a modified version of de Finetti's optimal dividend problem, incorporating fixed transaction costs and altering the surplus process by introducing two-val…
De Finetti's Poissonian Dividend Control Problem under Spectrally Positive Markov Additive Process
Lijun Bo, Wenyuan Wang, Kaixin Yan
We study a De Finetti's optimal dividend and capital injection problem under a Markov additive model. The surplus process without dividend and capital injection is assumed to follo…
