Erik Ekstrom, Johan Tysk
We study convexity and monotonicity properties for prices of bonds and bond options when the short rate is modeled by a diffusion process. We provide conditions under which convexi…

Properties of option prices in models with jumps
Erik Ekström, Johan Tysk
We study convexity and monotonicity properties of option prices in a model with jumps using the fact that these prices satisfy certain parabolic integro-differential equations. Con…
