The Bayesian Hidden Markov Chain Modeling of the Ghana COVID-19 Blood Type Infection Distribution

Ratio Mathematica
This work uses the Bayesian Poisson-Hidden Markov Model (BP-HMM) to develop a model that properly describes the blood type distribution among newly diagnosed COVID-19 patients.

Efficiency in Pure‐Exchange Economies With Risk‐Averse Monetary Utilities

Mathematical Finance, EarlyView.
ABSTRACT We study Pareto efficiency in a pure‐exchange economy where agents' preferences are represented by risk‐averse monetary utilities. These coincide with law‐invariant monetary utilities, and they can be shown to correspond to the class of monotone, (quasi‐)concave, Schur concave, and translation‐invariant utility functionals. This covers a large

Upper Comonotonicity and Risk Aggregation Under Dependence Uncertainty

Mathematical Finance, EarlyView.
ABSTRACT In this paper, we study dependence uncertainty and the resulting effects on tail risk measures, which play a fundamental role in modern risk management. We introduce the notion of a regular dependence measure, defined on multimarginal couplings, as a generalization of well‐known correlation statistics such as the Pearson correlation. The first

Macroeconomic Spillovers of Weather Shocks Across U.S. States

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We estimate the short‐run effects of weather‐related disasters on local economic activity and cross‐border spillovers that operate through economic linkages between U.S. states. To this end, we use emergency declarations triggered by natural disasters and estimate their effects using a monthly global vector autoregressive (GVAR) model for U.S.

How do US States Approach Multi‐Year Expenditure Forecasting?

Public Budgeting &Finance, EarlyView.
Abstract In the United States, 30 states publish multi‐year expenditure forecasts, while the remaining exhibit variation in their financial planning practices. Building on the literature examining budget forecasts, this study provides insights from interviews with eight states selected using a typology from a cluster analysis.
