Risk classification with on‐demand insurance
Journal of Risk and Insurance, Volume 90, Issue 4, Page 975-990, December 2023., 2023 Abstract On‐demand insurance is an innovative business model from the InsurTech space, which provides coverage for episodic risks. It makes use of a simple fact in a practical way: People differ in their frequency of exposure as well as the probability of loss.

Improving risk classification and ratemaking using mixture‐of‐experts models with random effects
Journal of Risk and Insurance, Volume 90, Issue 3, Page 789-820, September 2023., 2023 Abstract In the underwriting and pricing of nonlife insurance products, it is essential for the insurer to utilize both policyholder information and claim history to ensure profitability and proper risk management. In this paper, we apply a flexible regression model with random effects, called the Mixed Logit‐weighted Reduced Mixture‐of‐Experts, which ...

Approximation of Zero-Inflated Poisson Credibility Premium via Variational Bayes Approach
Risks, 2022 While both zero-inflation and the unobserved heterogeneity in risks are prevalent issues in modeling insurance claim counts, determination of Bayesian credibility premium of the claim counts with these features are often demanding due to high ...

Who captures whom? Regulatory misperceptions and the timing of cognitive capture
Regulation &Governance, Volume 17, Issue 1, Page 43-60, January 2023., 2023 Abstract To explain cognitive capture, economic sociologists often examine the structure of relationships between regulators and market participants. This paper argues that the nature of regulators' misperception should be subject to analysis as well. Different types of misperceptions develop over timelines of varying lengths.

Reinventing the utility for distributed energy resources: A proposal for retail electricity markets
Advances in Applied Energy, 2021 In this paper we propose a distribution-level retail electricity market operated by a Distribution System Operator (DSO), to permit participation for small-scale distributed energy resources (DERs) in a real-time energy market. The retail market is built
