    "abstract": "An exact formula for the distribution of lifetimes in coherent-noise models\nand related models is derived. For certain stress distributions, this formula\ncan be analytically evaluated and yields simple closed expressions. For those\ntypes of stress for which a closed expression is not available, a numerical\nevaluation can be done in a straightforward way. All results obtained are in\nperfect agreement with numerical experiments. The implications for the\ncoherent-noise models\u0027 application to macroevolution are discussed.",
