Abstract
Modifications of the Bekenstein-Hawking area law for black holes are crucia l in order to find agreement between the microscopic entropy based on state counting and the macroscopic entropy based on an effective field theory cc mputation. We discuss this and related issues for the case of four-dimensio nal N = 2 supersymmetric black holes. We also briefly comment on the state counting for N = 4 and 8 black holes.
