Lifts of continuous and Hölder alpha curves in the configuration space MN/SN$M^N/S_N$

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract In this paper, we study the quotient space X=MN/SN$X = M^N / S_N$ of equivalence classes of N$N$‐tuples in a metric space (M,dM)$(M, d_M)$, equipped with the metric induced by the minimal total pairing distance. Given a continuous path F:(0,1)→X$F: (0,1) \rightarrow X$, we prove that there exist continuous functions f1,⋯,fN:(0,1)→M$f_1, \dots,

Sustainability and Its Seven Sisters

open access: yesNatural Resource Modeling, Volume 39, Issue 1, February 2026.
ABSTRACT There are many concepts of sustainability. Robert Solow argued that sustainability would consist of conserving human well‐being over the “very long run”, through the interactions of the environment and other stocks in human decisions and activity.

On the Provision of International Public Goods in Dynamic Open Economies

open access: yesReview of International Economics, Volume 34, Issue 1, Page 198-218, February 2026.
ABSTRACT This study develops a dynamic two‐country model with an international public good, the stock of which positively affects the productivity of the private‐goods sectors in each country, and the evolution of the stock is determined by each country's voluntary contribution in the form of public investment. Two scenarios are examined: A cooperative
