Pairwise Imitation and Tournament Graphs

International Economic Review, EarlyView.
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 ...

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies

International Economic Review, EarlyView.
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes

International Statistical Review, EarlyView.
Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.

A Generalized ARFIMA Process with Markov-Switching Fractional Differencing Parameter [PDF]

We propose a general class of Markov-switching-ARFIMA processes in order to combine strands of long memory and Markov-switching literature. Although the coverage of this class of models is broad, we show that these models can be easily estimated with the

Resource partitioning among algal turf‐feeding fishes on a tropical artificial shoreline

Journal of Fish Biology, EarlyView.
Abstract Rapid coastal development has led to the proliferation of artificial structures along urban shorelines. Numerous studies have shown that patterns of fish diversity associated with these novel habitats are driven by physical habitat complexity; however, trophic‐mediated processes in shaping these patterns remain poorly understood.

A Markov Switching Model of the Merit Order to Compare British and German Price Formation [PDF]

The objective of this paper is to develop a model to determine the price formation of wholesale electricity markets. For that purpose, we model wholesale electricity prices depending on the prices of fuels (coal and natural gas) and of CO2 emission ...

Generalizing Determinacy under Monetary and Fiscal Policy Switches: The Case of the Zero Lower Bound

Journal of Money, Credit and Banking, EarlyView.
Abstract In a fixed‐regime context, it has been established since the work of Leeper (1991) that a determinate and unique equilibrium can be achieved under both monetary dominance (characterized by an active monetary policy and a passive fiscal policy) and fiscal dominance (characterized by an active fiscal policy and a passive monetary policy) regimes

Association between Markov regime-switching market volatility and beta risk: Evidence from Dow Jones industrial securities [PDF]

In this paper, the volatility of the return generating process of the market portfolio and the slope coefficient of the market model is assumed to follow a Markov switching process of order one.
