Scenario-based actuarial climate risk assessment via calibration of the DICE model to the shared socioeconomic pathways

Daisuke Murakami, Pavel V. Shevchenko, Tomoko Matsui +2

Accounting for climate-related risks is an emerging problem for life insurers around the world. In this paper, we demonstrate how scenario trajectories for global temperature can b…

Fast spatio-temporally varying coefficient modeling with reluctant interaction selection

Daisuke Murakami, Shinichiro Shirota, Seiji Kajita +1

Spatially and temporally varying coefficient (STVC) models are currently attracting attention as a flexible tool to explore the spatio-temporal patterns in regression coefficients.…

Solving stochastic climate-economy models: A deep least-squares Monte Carlo approach

Aleksandar Arandjelović, Pavel V. Shevchenko, Tomoko Matsui +2

Stochastic versions of recursive integrated climate-economy assessment models are essential for studying and quantifying policy decisions under uncertainty. However, as the number…

Sub-model aggregation for scalable eigenvector spatial filtering: Application to spatially varying coefficient modeling

Daisuke Murakami, Shonosuke Sugasawa, Hajime Seya +1

This study proposes a method for aggregating/synthesizing global and local sub-models for fast and flexible spatial regression modeling. Eigenvector spatial filtering (ESF) was use…

Data-Driven Framework for Uncovering Hidden Control Strategies in Evolutionary Analysis

Nourddine Azzaoui, Tomoko Matsui, Daisuke Murakami

We have devised a data-driven framework for uncovering hidden control strategies used by an evolutionary system described by an evolutionary probability distribution. This innovati…
