Long‐run confidence: Estimating uncertainty when using long‐run multipliers

American Journal of Political Science, EarlyView.
Abstract Researchers are often interested in the long‐run relationship (LRR) between variables where the dependent variable has dynamic properties. Though determining the long‐run multiplier (LRM) for an independent variable is straightforward, correctly estimating the significance of the LRM is often difficult, especially when time series are short ...

Between Cryptocurrencies' Risk and Crypto Environmental Attention: The Crypto Environment Attention Index and Volatility in the Cryptocurrencies Market Nexus

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT This study investigates the impact of environmental attention on cryptocurrency market volatility by introducing the Crypto Environmental Attention Index (CEAI), a new metric inspired by Wang et al. (2022) and constructed using daily web search data.

Environmental Legitimation in A Global Context: Emerging Market Multinational Enterprises Versus Developed Market Multinational Enterprises

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT The purpose of this paper is to study the differences and similarities between emerging market multinationals (EMNEs) and developed market multinationals (DMNEs) in their levels of adoption of environmental management policies and environmental disclosure practices when they increase their international diversification.

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Detecting Critical Change in Dynamics Through Outlier Detection with Time‐Varying Parameters

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Intensive longitudinal data are often found to be non‐stationary, namely, showing changes in statistical properties, such as means and variance‐covariance structures, over time. One way to accommodate non‐stationarity is to specify key parameters that show over‐time changes as time‐varying parameters (TVPs). However, the nature and dynamics of
