Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering

Mathematical Finance, EarlyView.
ABSTRACT Whereas data on implied volatilities are available for a large number of assets, this is less frequently the case of implied covolatilities. We introduce a new approach based on static and dynamic Wishart models to solve this problem of missing data.

Estimating Aggregate Relationships in Panel Data via the LASSO

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This article is concerned with the estimation of aggregate relationships among a potentially large number of panel data variables in the presence of unobserved heterogeneity in the form of interactive effects, an empirically very relevant scenario that has not been considered before.

Multi‐Elemental Analysis for Geographical Tracing of Chickpeas Produced in Nearby Locations Around a Protected Geographical Indication

Plant, Cell &Environment, EarlyView.
ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed
