On graphs that do not contain a subdivision of the complete graph on four vertices as an induced subgraph [PDF]
We prove a decomposition theorem for graphs that do not contain a subdivision of the complete graph on four vertices as an induced subgraph.Induced, subgraph, decomposition.

The impact of co‐payments for nursing home care on care use and welfare
Journal of Risk and Insurance, EarlyView.Abstract We assess the impact of an increase in the co‐payments for nursing home care on care use and welfare. Nursing home residents often have to pay substantial user fees, which expose them to a financial risk. Co‐payments may incentivize efficient care use, but empirical evidence is limited. We leverage a reform in the Netherlands that increased co‐

Selection and screening in cyber insurance markets
Journal of Risk and Insurance, EarlyView.Abstract This paper studies how information frictions shape demand, screening, and contract design in the U.S. cyber insurance market. I develop a framework in which firms sort into coverage based on latent cyber risk while insurers screen using coarse signals and manage residual exposure more through coverage quantities than through price.

Partitioning a permutation graph: algorithms and an application. [PDF]
In this paper we discuss the problem of partitioning a permutation graph into cliques of bounded size, and describe a real-life application of this problem encountered at a manufacturing company.

The fundamental theorem of asset pricing with and without transaction costs
Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Recursive Methods in Discounted Stochastic Games: An Algorithm for delta Approaching 1 and a Folk Theorem [PDF]
We present an algorithm to compute the set of perfect public equilibrium payoffs as the discount factor tends to one for stochastic games with observable states and public (but not necessarily perfect) monitoring when the limiting set of (long-run ...

Modern Theology, EarlyView.Abstract This essay, designed as a complement to opinions expressed by Rowan Williams and some speakers at the conference in his honour, explores features of early Christianity which suggest a positive evaluation of artificial intelligence. Noting that the fear of reducing humans to machines has been joined in the modern age by the fear that machines ...

Why Are All the Sets All the Sets?
Noûs, EarlyView.ABSTRACT Necessitists about set theory think that the pure sets exists, and are the way they are, as a matter of necessity. They cannot explain why the sets (de rebus) are all the sets. This constitutes the Ur‐Objection against necessitism; it is the primary motivation cited by potentialists about set theory.

Noûs, EarlyView.ABSTRACTProbabilism is the thesis that the degrees of belief of rational agents behave like Kolmogorovian probabilities. There are quite different lines of argument for probabilism in the literature, including Dutch book arguments, arguments based on representation theorems, and epistemic utility arguments. This paper focusses on the Dutch book line of

Social welfare effects of annuitization in small open economies
The Scandinavian Journal of Economics, EarlyView.Abstract This paper develops a theory of when annuitization improves or reduces social welfare. The analysis is based on a small open economy with exogenous prices, populated by overlapping generations of non‐altruistic agents. Annuities provide longevity risk insurance and above‐market returns, but also reduce accidental bequests that transfer ...
