Hierarchical Regularizers for Reverse Unrestricted Mixed Data Sampling Regressions

open access: yesJournal of Forecasting, EarlyView.
Abstract Reverse Unrestricted MIxed DAta Sampling (RU‐MIDAS) regressions are used to model high‐frequency responses by means of low‐frequency variables. However, due to the periodic structure of RU‐MIDAS regressions, the dimensionality grows quickly if the frequency mismatch between the high‐ and low‐frequency variables is large.

Fundamentals Models Versus Random Walk: Evidence From an Emerging Economy

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We analyze the predictive power of fundamentals versus random walk models for horizons from 1 to 24 months in an emerging market. Specifically, we investigate what fundamentals models outperform random walk during periods of appreciation and depreciation of the exchange rate.

Retrofitting Low Carbon Aviation Fuels Processes From Natural Gas to Renewables Energy‐Based Systems

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The aviation sector's dependence on high‐energy‐density fuels presents a challenge for decarbonization. This study evaluates the economic and environmental feasibility of retrofitting a gas‐to‐liquid (GTL) plant for low carbon aviation fuel (LCAF) production using solar electrification, an advanced reformer unit (CARGEN), and a hybrid ...

Communalizing private costs: Ownership concentration, institutions, and corporate environmental performance

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary We extend the property rights theory to show that stronger ownership control incentivizes owners to push for communalizing private environmental costs unless counterbalancing internal and external governance mechanisms are prevalent. Using a sample of 16,286 observations for 3275 firms across 43 countries between 2008 and 2017,
