A Stochastic Tree for Bubble Asset Modelling and Pricing

Journal of Time Series Analysis, Volume 46, Issue 5, Page 932-944, September 2025.
ABSTRACT We introduce a new stochastic tree representation of a strictly stationary submartingale process for modelling, forecasting, and pricing speculative bubbles on commodity and cryptocurrency markets. The model is compared to other trees proposed in the literature on bubble asset modelling and stochastic volatility approximation. We show that the

A Novel Test for the Presence of Local Explosive Dynamics

Journal of Time Series Analysis, Volume 46, Issue 5, Page 966-980, September 2025.
ABSTRACT In economics and finance, speculative bubbles take the form of locally explosive dynamics that eventually collapse. We propose a test for the presence of speculative bubbles in the context of mixed causal‐noncausal autoregressive processes.

Has the Free‐Rider Problem Been Improved in NATO? Evidence From a Novel TVP‐VAR‐Based Connectedness Approach

Scottish Journal of Political Economy, Volume 72, Issue 4, September 2025.
ABSTRACT Previous studies have offered static evidence of free‐riding behavior in military alliances; however, dynamic evidence remains largely unexplored. To address this gap, this study employs a time‐varying parameter vector autoregressive (TVP‐VAR) connectedness approach. This method provides dynamic insights, allowing us to identify unusual shifts
