Oil shocks and stock market volatility of the BRICS: A GARCH-MIDAS approach
, 2020 In this study, we employ the GARCH–MIDAS (Generalised Autoregressive Conditional Heteroskedasticity variant of Mixed Data Sampling) model to investigate the response of stock market volatility of the BRICS group of countries (Brazil, Russia, India, China,

Botanic and heritage gardens as living laboratories in the age of the polycrisis
PLANTS, PEOPLE, PLANET, EarlyView.Societal Impact Statement Cities face intertwined crises of climate, biodiversity loss and social disconnection. We show how botanic and heritage gardens can help address these challenges as living laboratories to generate place‐based evidence and public engagement.

Midas and Bridge Equations [PDF]
SSRN Electronic Journal, 2014 This paper compares two single-equation approaches from the recent nowcast literature: Mixed-data sampling (MIDAS) regressions and bridge equations. Both approach are used to nowcast a low-frequency variable such as quarterly GDP growth by higher-frequency business cycle indicators.

Markov-Switching MIDAS Models [PDF]
This paper introduces a new regression model - Markov-switching mixed data sampling (MS-MIDAS) - that incorporates regime changes in the parameters of the mixed data sampling (MIDAS) models and allows for the use of mixed-frequency data in Markov ...
