"We study blockchain adoption in insurance-reinsurance markets. Operating costs decrease with the adoption rate, since verification and storage costs are shared. We quantify how the equilibrium adoption decisions depend on contract characteristics, risk aversions, potential losses and cost structure. The reinsurance firm internalizes the benefits of adoption on other insurance firms, acting as a central planner. We characterize the adoption gap between decentralized (Nash) and centralized blockchain consortium."
"Using Cat bonds to transfer catastrophe risk substitutes not only the use of Cat reinsurance but also non-Cat reinsurance in the hard market, implying Cat bonds affect a ceding insurer’s diversification in both Cat and non-Cat lines of business in the reinsurance market."
"... most modified coinsurance is purchased from reinsurers located in countries with lower regulatory capital requirements and within the same insurance holding group. Our findings expose how insurers use reinsurance to obfuscate their asset risk."
"... the reinsurance chain with ambiguity aversions in increasing order is optimal from the perspectives of both selfish individual companies and an unselfish central planner."
"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."
"... we study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a normal distribution with a given mean and a given variance."
"…. the surplus of an insurance company is routinely approximated by a Brownian motion, as opposed to the geometric Brownian motion used to model assets in finance. Furthermore, exposure to risk is controlled "downwards" via reinsurance, rather than "upwards" via risky investments. This leads to interesting qualitative differences in the optimal solutions."
"... we develop a granular occurrence and development model for non-life claims that allows to resolve the inconsistency in traditional pricing techniques between actual, complete observations on the one hand and best estimates on the other hand. We illustrate our proposed model on a reinsurance portfolio, where large uncertainties in the best estimates originate from long reporting and settlement delays, low claim frequencies and heavy (even extreme) claim sizes."
"Stackelberg game. The reinsurer is the leader in the game and maximizes its expected utility by selecting its optimal investment strategy and a safety loading in the reinsurance contract it offers to the insurer. The reinsurer can assess how the insurer will rationally react on each action of the reinsurer. The insurance company is the follower and maximizes its expected utility by choosing its investment strategy and the amount of reinsurance the company purchases at the price offered by the reinsurer.

"Traditional techniques for calculating outstanding claim liabilities such as the chain ladder are notoriously at risk of being distorted by outliers in past claims data. Unfortunately, the literature in robust methods of reserving is scant, with notable exceptions … we put forward two alternative robust bivariate chain-ladder techniques to extend the approach of Verdonck and Van Wouwe (2011)."
