A joint model of cost and churn for the insurance industry

Journal of Risk and Insurance, EarlyView.
Abstract In insurance markets, claim costs are highly variable, heavy‐tailed, and difficult to predict. At the same time, policyholder retention and lapse behavior (customer churn) are critical determinants of long‐term profitability and solvency. Most existing models in the literature treat claim costs and lapses as independent, overlooking potential ...

Insurance as commitment?

Journal of Risk and Insurance, EarlyView.
Abstract Most insurance decisions combine risk management and an intertemporal dimension. Yet while non‐canonical behavioral models have been applied extensively to the risk management aspect, they are mostly missing from the intertemporal component. We expand insurance demand theory by showing that individuals who perceive themselves as present‐biased

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Coordinating Bank Dividend and Capital Regulation

Mathematical Finance, EarlyView.
ABSTRACT This paper examines how state‐dependent dividend restrictions (taxes and bans) and capital requirements influence a bank's capital buffer accumulation and risk‐taking decisions. In the model, the bank distributes dividends and issues costly equity to maximise shareholder value, while its loans generate stochastic income under time‐varying ...

Looking for trouble: A common threat‐detection mechanism underlying pain, fear, and anxiety

Mind &Language, EarlyView.
I put forward a novel cognitive architecture for pain, fear, and anxiety, according to which these three capacities are underpinned by a common threat‐detection mechanism. This mechanism takes information about potential threats as input, assesses whether the threat is actual and, if it deems it is, outputs a threat representation.

Lost in Communication? Beyond the Aporia of Kenosis

Modern Theology, EarlyView.
Abstract Contemporary kenoticist Christologies reach an impasse when they conflate metaphorical and analogical predication. Interpreting divine “self‐emptying” in analogical terms—as divine self‐divestment—generates ethical concerns as well as philosophical, exegetical, and doctrinal difficulties.
