Price Impact on Term Structure [PDF]

open access: yesSSRN Electronic Journal, 2020
We introduce a first theory of price impact in presence of an interest-rates term structure. We explain how one can formulate instantaneous and transient price impact on bonds with different maturities, including a cross price impact that is endogenous to the term structure.

Terrestrial Impact Structures

open access: yesAnnual Review of Earth and Planetary Sciences, 1987
Impact structures are the dominant landform on planets that have retained portions of their earliest crust. The present surface of the Earth, however, has comparatively few recognized impact structures. This is due to its relative youthfulness and the dynamic nature of the terrestrial geosphere, both of which serve to obscure and remove the impact ...
