Monopoly Versus Dual‐Channel Distribution With Multiple Retailers

The Journal of Industrial Economics, EarlyView.
ABSTRACT This paper examines how downstream competition shapes a manufacturer's decision to adopt a dual‐channel structure—supplying independent retailers via secret two‐part tariff contracts while also operating a direct channel. We show that the shape of the inverse demand function plays a key role in this decision.

A joint model of cost and churn for the insurance industry

Journal of Risk and Insurance, EarlyView.
Abstract In insurance markets, claim costs are highly variable, heavy‐tailed, and difficult to predict. At the same time, policyholder retention and lapse behavior (customer churn) are critical determinants of long‐term profitability and solvency. Most existing models in the literature treat claim costs and lapses as independent, overlooking potential ...

The Cross and Conflict: How Do Christians Impact Protest Dynamics?

Journal for the Scientific Study of Religion, EarlyView.
ABSTRACT This study examines the relationship between Christian actors, practices, and sacred sites in US protests and demonstrations, focusing on how political ideology shapes conflict outcomes. Using event‐level data from the Armed Conflict Location & Event Data Project (ACLED), the analysis explores 63,000 protest events from 2020 to 2024 ...

Testing Distributional Granger Causality With Entropic Optimal Transport

Journal of Time Series Analysis, EarlyView.
ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.

Multiple Chains Markov Switching Vector Autoregression

Journal of Time Series Analysis, EarlyView.
ABSTRACT Both the U.S. stock and bond returns exhibit distinct Markovian regimes. However, because these regimes display limited coherence, conventional models typically require highly parameterized systems to adequately capture their joint distribution.

Penalized Convex Estimation in Dynamic Location Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.
