EM Estimation for the Poisson-Inverse Gamma Regression Model with Varying Dispersion: An Application to Insurance Ratemaking

Risks, 2020
This article presents the Poisson-Inverse Gamma regression model with varying dispersion for approximating heavy-tailed and overdispersed claim counts. Our main contribution is that we develop an Expectation-Maximization (EM) type algorithm for maximum ...

Enhance food plant diversity conservation and use through greater coordination between genebanks and botanic gardens

PLANTS, PEOPLE, PLANET, EarlyView.
Food plants are vital to human and planetary health, but their diversity is threatened, making food security, nutrition, and environmental goals more difficult to achieve. Food plant diversity conservation, research, and education can be enhanced through collaboration between sectors, including genebanks and botanic gardens, which possess complementary

A Survey of the Individual Claim Size and Other Risk Factors Using Credibility Bonus-Malus Premiums

Risks, 2020
In this paper, a flexible count regression model based on a bivariate compound Poisson distribution is introduced in order to distinguish between different types of claims according to the claim size. Furthermore, it allows us to analyse the factors that

Determinants of Perceived Public Value in PPPs for Urban Transport in Developing Contexts: An Ex‐Ante Structural Analysis of Guadalajara Light Rail Line 4

Sustainable Development, EarlyView.
ABSTRACT Public–private partnerships (PPPs) are widely used to deliver urban rail in developing contexts, although their contribution to public value remains contested. This paper offers an ex‐ante analysis of the determinants of perceived public value, using Mexico's Guadalajara Light Rail Line 4 as an illustrative case.

Modeling and Performance of Bonus-Malus Systems: Stationarity versus Age-Correction

Risks, 2014
In a bonus-malus system in car insurance, the bonus class of a customer is updated from one year to the next as a function of the current class and the number of claims in the year (assumed Poisson).

Is Sleep Bruxism Associated With General Quality of Life? Insights From the EPISONO Population‐Based Study

Journal of Oral Rehabilitation, EarlyView.
“In this population‐based study, sleep bruxism was assessed using self‐report and polysomnography (PSG), and associations with quality of life were evaluated using the WHOQOL‐Bref. Self‐reported sleep bruxism was associated with lower satisfaction with health and poorer quality of life in the social relationships domain, whereas PSG‐based and combined ...

The Efficiency of a Bonus-Malus System [PDF]

ASTIN Bulletin, 1978
AbstractThe concept efficiency of a bonus-mains system was defined, apparently in a totally different way, consecutively by Loimaranta (1972) and Lemaire (1975, 1976). In this paper we start with a more general model that leads us to a definition of efficiency that contains both earlier ones as special cases.

Welfare implications of fair and accountable insurance pricing

Journal of Risk and Insurance, EarlyView.
Abstract This paper introduces an empirical framework to evaluate the welfare implications of fair and accountable insurance pricing by modeling the complete pricing process, including demand and price optimization. Moving beyond traditional cost modeling, we analyze both discrimination‐related fairness criteria and broader regulatory constraints, such
