A UNIVERSAL OPTIMAL CONSUMPTION RATE FOR AN INSIDER [PDF]

open access: yesMathematical Finance, 2006
We consider a cash flow X(c) (t) modeled by the stochastic equation image where B(·) and are a Brownian motion and a Poissonian random measure, respectively, and c(t) ≥ 0 is the consumption/dividend rate. No assumptions are made on adaptedness of the coefficients μ, σ, θ, and c, and the (possibly anticipating) integrals are interpreted in the forward
