Comovements in Trading activity: A Multivariate Autoregressive Model of Time Series Count Data Using Copulas [PDF]
This paper introduces the Multivariate Autoregressive Conditional Poisson model to deal with issues of discreteness, overdispersion and both auto- and cross-correlation, arising with multivariate counts.

ABSTRACT Despite the global emphasis on simultaneous achievement of higher growth and lower pollution (green growth), the dynamic link between eco‐innovation and CO2 emissions remains inadequately understood globally and specifically in Africa, with a complex and diverse institutional and regulatory landscape.

Martingales and First Passage Times of AR(1) Sequences [PDF]
Using the martingale approach we find sufficient conditions for exponential boundedness of first passage times over a level for ergodic first order autoregressive sequences (AR(1)).

ABSTRACT The transition to net zero (NZ) faces challenges such as uneven institutional readiness, fragmented policy frameworks and rising energy demands from population growth, economic expansion and artificial intelligence (AI). These obstacles are intensified by technological, financial and regulatory uncertainties that impede coordinated efforts ...

We propose a new framework for modelling time dependence in duration processes on financial markets. The well known autoregressive conditional duration (ACD) approach introduced by Engle and Russell (1998) will be extended in a way that allows the ...

Smart Cities Leading the Green Transition: Linking Open Innovation and Entrepreneurial Dynamics
ABSTRACT Smart cities today are vibrant spaces where technology, collaboration, and sustainability come together to shape a better future. The green transition in cities is not just about building greener infrastructure or cutting emissions. It also changes how people, institutions, and businesses think and act.

Robust estimation of the vector autoregressive model by a trimmed least squares procedure. [PDF]
The vector autoregressive model is very popular for modeling multiple time series. Estimation of its parameters is done by a least squares procedure. However, this estimation method is unreliable when outliers are present in the data, and there is a need

Decarbonization in Financial Turbulent Times: Global Value Chains and Regulatory Framework
ABSTRACT This study examines how participation in global value chains (GVCs) influences carbon emissions amid financial turbulence, with attention to cross‐country heterogeneity and distributional dynamics. Although existing research has explored trade–environment linkages, limited attention has been given to how GVC integration interacts with ...

ABSTRACT The circular economy (CE) has become a major focus in energy and environmental (E&E) research, as it helps advance sustainable development, improve resource efficiency and alleviate environmental pressure. Even so, the literature is still fragmented, particularly in the CE themes it explores, the levels of analysis it adopts and the methods ...
