The Long‐term Socioeconomic Impacts of Renewable Energy Deployment: Lessons From Case Studies in European Rural Regions

Journal of Regional Science, EarlyView.
ABSTRACT The new environmental and geopolitical situation has led to the need for a change in the current energy model. The infrastructures associated with renewable energies may represent an opportunity for economic growth, employment generation, and population recovery in rural territories.

Poisson count time series

Journal of Time Series Analysis, EarlyView.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

A Stochastic Tree for Bubble Asset Modelling and Pricing

Journal of Time Series Analysis, EarlyView.
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

Automated Bandwidth Selection for Inference in Linear Models With Time‐Varying Coefficients

Journal of Time Series Analysis, EarlyView.
ABSTRACT The problem of selecting the smoothing parameter, or bandwidth, for kernel‐based estimators of time‐varying coefficients in linear models with possibly endogenous explanatory variables is considered. We examine automated bandwidth selection by means of cross‐validation, a nonparametric variant of Akaike's information criterion, and bootstrap ...
