Transport Connectivity and Urban Development: The Case of Africa (1880–2020)

Geographical Analysis, Volume 58, Issue 1, January 2026.
ABSTRACT This paper investigates the interplay between population dynamics and transport connectivity in African municipalities from 1880 to 2020. Using an original historical dataset spanning African countries, we examine how proximity to railways and ports has shaped population dynamics over time.

Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering

Mathematical Finance, Volume 36, Issue 1, Page 48-66, January 2026.
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.
