Moments of two distributions in collective risk theory
Scandinavian Actuarial Journal, 1977Abstract This paper is motivated by Bartlett (1965) and Beekman (1966) in which approximation methods in collective risk theory are discussed. Here we generalize the results on moments given in these two papers, using less complicated techniques.

Note on the collective theory of risk
Scandinavian Actuarial Journal, 1968Abstract What follows has grown out of a discussion with Carl Philipson following a lecture [1] on the collective theory of risk. Although I give here nothing else but a refined interpretation of Paul Levy's form (see, e.g., [2], p. 322) of identically distributed random variables the result still seems of interest for all those working in the field of

Some problems in the collective theory of risk
Scandinavian Actuarial Journal, 1950Abstract In most works treating the ruin problem of an insurance company, the probability of ruin some time in the future is chiefly considered. The time variable is thus eliminated, which in most respects simplifies the problem theoretically. But as well from theoretical as from practical points of view it is also of interest to know the probability ...

Collective Approaches to Risk in Business: An Introduction to Plural Rationality Theory
North American Actuarial Journal, 2013This article initiates a discussion regarding Plural Rationality Theory, which began to be used as a tool for understanding risk 40 years ago in the field of social anthropology. This theory is now widely applied and can provide a powerful paradigm to understand group behaviors.

A Review of Modern Collective Risk Theory with Dividend Strategies
SSRN Electronic Journal, 2008In his seminal paper, Bruno de Finetti (1957) laid the foundations of what would become an increasingly popular branch of risk theory: the study of dividend strategies. The recent burst of research in this field encouraged the author to carry out a systematic literature review of modern collective risk theory with dividend strategies.

When does ruin occur in the collective theory of risk?
Scandinavian Actuarial Journal, 1955Abstract In the discussion on the practical applicability of the collective theory of risk to the insurance field some points have been raised, where it is argued that the conceptions of the theory do not correspond to the conditions prevailing in practice, thus entailing a serious reduction of its working value. Three such points will be considered in

Some supplementary researches on the collective risk theory
Scandinavian Actuarial Journal, 1932There are several different systems of risk technic which may be adopted in the mathematical treatment of the collective risk theory. Assuming th.e risk rates practically stabile, the following system, however, seems to be the simplest.

Collective Dangerous Behavior: Theory and Evidence on Risk-Taking [PDF]
, 2013 It is commonly found that uncertainty helps discipline economic agents in strategic contexts. Using a stochastic variant of the Nash Demand Game, we show that the presence of uncertainty may have a dramatically opposite effect. Cautious (efficient) and dangerous (inefficient) equilibria may co-exist regardless of agents’ risk preferences.

Drinking trajectories of at‐risk groups: Does the theory of the collectivity of drinking apply?
Drug and Alcohol Review, 2017AbstractIntroduction and AimsAlcohol consumption among Swedish adolescents has halved during the last decade. We aim to: (i) investigate whether the overall decrease in drinking may conceal an underlying heterogeneity in drinking trajectories across at‐risk groups that differ with respect to risk for drinking and; (ii) assess to what degree alcohol ...
