Modelling Heterogeneous Dependence in a Copula‐Linked By‐Production Frontier: Evidence From French Dairy Farms

ABSTRACT In agriculture, production technologies are often characterised by non‐linearities and stochastic dependence between outputs, particularly between desirable and undesirable outputs. This paper combines the copula‐based semi‐parametric framework for modelling heterogeneou...

The Spatial Structure of Competitive Interactions: Evidence From Public Procurement Networks in Quebec

How can functional procurement markets be delineated from observed bidding behavior? Using bid-level data from Quebec’s municipal paving sector (2012–2019), we construct a geographical bidder overlap (GBO) index measuring supply-side substitutability between postal codes. Gravity...

Net carbon losses in Central African forests revealed by high-resolution biomass change maps

Dense humid forests in Central Africa hold vast biomass carbon stocks but are increasingly affected by small-scale disturbances that are difficult to detect with current satellite observations. Here, we generate 10 m canopy height maps for 2019–2022 using deep learning with space...
