Sinking peatlands: Optimal control of subsidence

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 3, Page 926-953, May 2026.
Abstract Land subsidence threatens the living conditions of about 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in these areas requires lowering groundwater levels to keep the land sufficiently dry, which leaves future generations worse off by accelerating subsidence and increasing future costs.

Ambiguity Aversion, Portfolio Choice, and Life Expectancy

open access: yesInternational Economic Review, Volume 67, Issue 2, Page 633-655, May 2026.
ABSTRACT This paper studies how wealth and aging affect portfolio choices in a life‐cycle model with ambiguity aversion. Ambiguity aversion implies wealthier and older agents are endogenously more optimistic about risky asset returns, relative to poorer/younger agents. As life expectancy grows, old agents become even more optimistic, while young agents

Nonmonotonic reasoning in probabilistics [PDF]

open access: yes, 1998
In probabilistics, reasoning at optimum entropy (ME-reasoning) has proved to be a most sound and consistent method for inference. This paper investigates its properties in the framework of nonmonotonic reasoning. In particular, we show that ME-reasoning satisfies cumulativity and loop, and we focus on its connection to conditionals.

Nonmonotonic Reasoning via Possibility Theory

open access: yes, 2013
We introduce the operation of possibility qualification and show how. this modal-like operator can be used to represent "typical" or default knowledge in a theory of nonmonotonic reasoning. We investigate the representational power of this approach by looking at a number of prototypical problems from the nonmonotonic reasoning literature. In particular
