The past and the future of mortality
Dissertation(Universität Ulm, 2019-09-03)A variety of literature addresses the question of how the age distribution of deaths changes over time as life expectancy increases. However, corresponding terms such as extension, compression, or rectangularization are ... -
Essays in applied microeconomics : herding behavior, competition intensity and risk timing
Dissertation(Universität Ulm, 2019-08-20)We investigate whether credit rating agencies systematically follow each other's rating decisions. Therefore, we rely on the rotation of rating analysts within credit rating agencies and their impact on the rating. Using ... -
