Prof Vladimir Kaishev is a Professor of Actuarial Science at the Faculty of Actuarial Science and Insurance (FASI), Cass Business School, City University, London. He joined FASI in 2002. In 2001 he has been a visiting lecturer in actuarial mathematics at the Center of Actuarial Studies, University of Melbourne, Australia. From 1994 until 2000, Prof Kaishev was Head of the Department of Computational Stochastics at the Institute of Mathematics of the Bulgarian Academy of Sciences. He holds a PhD degree in statistics and information theory from the Moscow Technical University. He has been a visiting researcher at the Mathematics Research Center, University of Wisconsin- Madison, and at the University of California at Los Angeles. Prof Kaishev has also been a visiting lecturer at the Department of Actuarial Mathematics and Statistics, Heriot-Watt University, Edinburgh, at Sofia University "St. Kliment Ohridski" and has delivered invited lectures at Stanford University (Dept. of Statistics) and at a number of European universities and research institutions. His research interests are in actuarial mathematics, risk and ruin theory, reinsurance modeling, spline-functions and their applications to probability, statistics and actuarial science, competing risks and copulas. He has also worked on a number of applied research and consultancy projects in the field of actuarial science and insurance, chemistry, medicine, ship hydrodynamics. Prof Kaishev was the initiator of the re-establishment of the Bulgarian Actuarial Society in 1993 and has served as its president from 1993 to 2002.

Research Topics

risk and ruin theory

explicit formulae for the probability of ruin and related quantities in a general (non-classical) risk model, allowing dependence

dependent risk models and copulas

new classes of multivariate copulas; Estimation of multivariate Archimedean copulas; application of copulas in finance and insurance, e.g. competing risk models; New multivariate Levy processes allowing for modelling dependence e.g., dependent joint asset price dynamics

spline functions in actuarial science and statistics

new methods for geometrically designed variable knot regression splines and their actuarial and statistical applications

operational risk in insurance and banking

ruin probabilistic reserving (capital allocation) for operational risk

exotic option pricing

new Monte Carlo methods for pricing path dependent options in finance and life insurance

optimal reinsurance and Cat bonds

optimal reinsurance with respect to joint survival of cedent and reinsurer; efficient frontier approach to optimal reinsurance; Cat bonds versus reinsurance- the pricing perspective
