Stochastic mortality : modelling and optimal investment
, 2020 Nothing is more certain than death, nothing more uncertain than its hour. Even today the timepoint of death is unknown, but death will occur with certainty. In this work, the uncertainty of death time is included in our considerations of mortality modelling, optimal investment as insured under uncertain death time and optimal investment as insurance ...

Stochastic Mortality, Subjective Survival Expectations, and Individual Saving Behavior [PDF]
Theoretical studies suggest that unexpected changes in future mortality and survival probabilities (stochastic mortality) are important determinants of individuals’ decisions about consumption, saving, asset allocation, and retirement timing.

Are dairy cows replaced too early? Evidence from a structural model and cow‐level data
American Journal of Agricultural Economics, EarlyView.Abstract In past analyses of animal replacement decisions, studies have claimed that dairy farms often replace dairy cows too early to be maximizing profits. I estimate a structural model of asset replacement to determine the motives behind early replacement of dairy cows.

Incorporating time-series structure in medium-term recruitment projections
Scientia Marina, 2003 One of the key tasks in current fisheries research is to improve the performance, in terms of accuracy and utility, of projections of recruitment-driven population dynamics in the medium-term.

Delta and Gamma hedging of mortality and interest rate risk [PDF]
This paper studies the hedging problem of life insurance policies, when the mortality and interest rates are stochastic. We focus primar- ily on stochastic mortality. We represent death arrival as the rst jump time of a doubly stochastic process, i.e.

Animal Models and Experimental Medicine, EarlyView.Using F1 (C57BL/6J/Smad4+/− X CC) mice, we found that partial loss of Smad4 promotes liver carcinogenesis in a strain‐dependent manner, highlighting the importance of genetic modifiers in tumor susceptibility. The use of Collaborative Cross mice provides a valuable platform for uncovering genotype‐specific cancer susceptibilities in preclinical ...

Extremal behavior of stochastic volatility models [PDF]
, 2005 Empirical volatility changes in time and exhibits tails, which are heavier than normal. Moreover, empirical volatility has - sometimes quite substantial - upwards jumps and clusters on high levels.

Pharmacometric evaluation of pre‐referral rectal artesunate in children with severe malaria
British Journal of Clinical Pharmacology, EarlyView.Aims Parenteral artesunate is the preferred first‐line treatment for severe malaria. Pre‐referral rectal artesunate suppositories are recommended where parenteral treatment is inaccessible. In this study, we compared dihydroartemisinin exposure and model‐predicted early parasite clearance following rectal artesunate and intravenous artesunate in ...
