Survival and Value: the Conglomerate Case

Michela Altieri and Giovanna Nicodano

No 18198, CEPR Discussion Papers from Centre for Economic Policy Research

Abstract: This paper investigates the relationship between default probability and value when there is a selection bias due to missing controls for firm heterogeneous likelihood to survive in the sample. Our model delivers the following implications for the conglomerate case: (a) the sample conglomerate value increases in their default probability (b) the sample conglomerate discount falls together with their excess default probability with respect to focused companies (c) both effects disappear or switch sign when the analyst controls for survival probability. The data support the presence of a selection bias distorting downwards the relative value of sample firms with higher survival probability.
