Markup Centrality and International Incidence in Global Production Networks

Review of International Economics, Volume 34, Issue 4, Page 891-903, September 2026.
ABSTRACT This paper develops a framework to measure how markups amplify prices through global production networks and to attribute final‐demand price wedges to upstream country‐industry sources. The approach defines a compound markup as the ratio of observed prices to counterfactual pure‐cost prices that would prevail if all markups in the network were

Repelled Point Processes With Application to Numerical Integration

Scandinavian Journal of Statistics, Volume 53, Issue 3, Page 1101-1133, September 2026.
ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

Free semigroups of large critical exponent

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract For a convergence group equipped with an expanding coarse‐cocycle, we construct finitely generated free subsemigroups, which we call Bishop−−Jonessemigroups$\textit{Bishop--Jones semigroups}$, of critical exponent arbitrarily close to but strictly less than the critical exponent of the ambient group.
