TY - GEN A1 - Reiss, Oliver A1 - Schoenmakers, John A1 - Schweizer, Martin T1 - From structural assumptions to a link between assets and interest rates N2 - We derive a link between the short rate and a new index constructed in a multiasset economy. This uses two structural assumptions: The volatility structure of the assets is rigidly spherical , and the short rate function is homogeneous of degree 0. We give clear motivations for the assumptions, and our main result is economically intuitive and testable from observed data. A preliminary empirical study illustrates how one can test such results.
