"... insurance pricing can accelerate the incorporation of climate risk in asset markets."

"... we characterize Pareto-optimal risk-sharing contracts in a market with multiple policyholders and one representative insurer. With minimal assumptions on the risk measures of the parties involved, we characterize Pareto optimality in terms of the minimization of a sum of the agents' risk positions, and we relate it to both the core and coalitional stability of an associated market game. In the special case of coherent risk measures, the optimal indemnity schedules are further characterized in explicit form, in terms of what can be called "worst-case probability measures". "

"We distinguish three main types of cyber risks: idiosyncratic, systematic, and systemic cyber risks. While for idiosyncratic and systematic cyber risks, classical actuarial and financial mathematics appear to be well-suited, systemic cyber risks require more sophisticated approaches that capture both network and strategic interactions."

"This model allows to be more conservative regarding extreme events while keeping tractability. We give a method based on Conditional Least Squares to estimate the parameters on daily data and estimate our model on eight major European cities... This new model allows to better assess the risk related to temperature volatility."

"The potential use of the proposed risk measures in insurance is illustrated by two concrete applications, capital risk allocation and premia calculation under uncertainty."

"The higher the degree of loss aversion, the lower is the likelihood to invest in other risk management activities is when self-protection is implemented. Our results help to explain the lack of demand for catastrophe insurance or cyber risk insurance and have important implications for corporate risk management and public policy."

"... at least in financial terms, the associated losses can be covered by insurance contracts. The role of actuaries is to develop adequate contract structures, calculate correct premiums, and implement quantitative risk management in insurance firms."

"Using this framework, I provide comparative statics results on the effects of exogenous economic factors on the optimal design of these plans. In particular, I examine the effect of risk aversion, forecast improvements, early action benefits, and likelihood of risky event on the optimal financing amount and forecast trigger."

"Our main purpose is to provide a convenient analytic model that explains both the pattern of observed customer behavior and the pattern of insurance contracts most often observed in practice: these consist of menus of several deductible-premium pairs, or menus of insurance with coverage limits-premium pairs."

"The objective of this paper is to discuss the underlying principles and assumptions of valuation under Solvency II and to analyse concepts such as the best estimate and the cost-of-capital risk margin, hedgeable and non-hedgeable risks, market value of risk, as well as economic capital and expected and unexpected losses."
