Interest rate sensitivity of callable bonds and higher-order approximations

Dow, Scott S.; Orfanos, Stefanos C. - In: Risks : open access journal 13 (2025) 4, pp. 1-24

Certain fixed-income securities, such as callable bonds and mortgage-backed securities subject to prepayment, typically exhibit negative convexity at low yields and cannot be adequately immunized through duration and convexity-matching alone. To address this residual risk, we examine the...

Finite approximations of the Sion-Wolfe game

Aspect, Leopold; Ewerhart, Christian - 2025 - Revised version, May 2025

analyze finite-grid approximations of the Sion-Wolfe game. We find that, as the number of grid points tends to infinity and … the payoff function approaches that of the infinite game, the limiting value of finite approximations may lie within, on …-person zero-sum games, when using finite approximations for the analysis of infinite games. …

Approximations and inference for nonparametric production frontiers

Daraio, Cinzia; Simar, Léopold - 2022

drawbacks and provide approximations of these coefficients of economic interest by "smoothing" the popular nonparametric … both the full and the partial (robust) frontiers. We consider parametric but also flexible approximations based on local …
