Longevity, Health, and Housing Risk Management in Retirement

The Journal of Finance, EarlyView.
ABSTRACT Annuities, long‐term care insurance, and reverse mortgages remain puzzlingly unpopular to manage post‐retirement longevity, health, and housing price risks. We use a flexible life‐cycle model structurally estimated with a unique stated‐preference survey experiment of Canadian households to understand why. Key factors include high risk aversion,

Sequential Outlier Detection in Nonstationary Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT A novel method for sequential outlier detection in nonstationary time series is proposed. The method tests the null hypothesis of “no outlier” at each time point, addressing the multiple testing problem by bounding the error probability of successive tests, using extreme‐value theory. The asymptotic properties of the test statistic are studied

Spatial dynamics for a non-monotone reaction-diffusion system with spatio-temporal delay

Mathematics in Applied Sciences and Engineering
In this paper, we study the spreading speed and traveling wave solutions of a non-monotone reaction-diffusion system with spatio-temporal delay. By constructing a pair of auxiliary systems and using the Schauder 's fixed point theorem, the existence of ...

Belief Change in Nonmonotonic Multi-Context Systems [PDF]

, 2013
Brewka and Eiter's nonmonotonic multi-context system is an elegant knowledge representation framework to model heterogeneous and nonmonotonic multiple contexts. Belief change is a central problem in knowledge representation and reasoning. In this paper we follow the classical AGM approach to investigate belief change in multi-context systems ...

Sequent-Type Calculi for Systems of Nonmonotonic Paraconsistent Logics [PDF]

Electronic Proceedings in Theoretical Computer Science, 2020
Paraconsistent logics constitute an important class of formalisms dealing with non-trivial reasoning from inconsistent premisses. In this paper, we introduce uniform axiomatisations for a family of nonmonotonic paraconsistent logics based on minimal inconsistency in terms of sequent-type proof systems.

Pairwise Imitation and Tournament Graphs

International Economic Review, Volume 67, Issue 3, Page 937-955, August 2026.
ABSTRACT This paper investigates strategic dynamics under the behavioral rule of pairwise interact and imitate (PII), which requires minimal information and emphasizes outperforming opponents in pairwise interactions. We characterize PII using weak tournament graphs and, for a broad class of dynamics, establish a one‐shot stability result for ...

A new nonmonotone line search technique for unconstrained optimization [PDF]

, 2008
In this paper, we propose a new nonmonotone line search technique for unconstrained optimization problems. By using this new technique, we establish the global convergence under conditions weaker than those of the existed nonmonotone line search ...

Minimal wave speed on a diffusive SIR model with nonlocal delays

Electronic Journal of Differential Equations, 2018
This article concerns the minimal wave speed of a diffusive SIR model with nonlocal delays, in which the dynamics of disease has no positive outbreak threshold. By constructing a pair of super and sub-solutions, we establish the existence of traveling

A Model of Punitive Voting

Journal of Public Economic Theory, Volume 28, Issue 4, August 2026.
ABSTRACT I analyze a two‐period model of political competition where voters care about candidates' integrity. Candidates must trade off implementing their preferred policy against maintaining their electoral promises. Voters punish candidates who deviate from electoral promises by voting for their opponent.

Distributed Evaluation of Nonmonotonic Multi-context Systems

Journal of Artificial Intelligence Research, 2015
Multi-context Systems (MCSs) are a formalism for systems consisting of knowledge bases (possibly heterogeneous and non-monotonic) that are interlinked via bridge rules, where the global system semantics emerges from the local semantics of the knowledge bases (also called “contexts”) in an equilibrium.
