Choosing Your Nonmonotonic Logic: A Shopper’s Guide [PDF]

open access: yes, 2018
The paper presents an exhaustive menu of nonmonotonic logics. The options are individuated in terms of the principles they reject. I locate, e.g., cumulative logics and relevance logics on this menu.

The Complexity of Reasoning for Fragments of Default Logic [PDF]

open access: yes, 2009
Default logic was introduced by Reiter in 1980. In 1992, Gottlob classified the complexity of the extension existence problem for propositional default logic as $\SigmaPtwo$-complete, and the complexity of the credulous and skeptical reasoning problem as

Brook no compromise: How to negotiate a united front

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Negotiating factional conflict is crucial to successful coordination: Political parties, rebel alliances, and authoritarian elites must all overcome internal disagreements to survive and achieve collective aims. Actors in these situations sometimes employ hardball tactics to block outcomes they dislike, but at the risk of causing coordination ...

Financial Statement Information and Equity Value: The Role of Real Options Characteristics

open access: yesFinancial Management, EarlyView.
ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...

Nonmonotonic Skeptical Consequence Relation in Constrained Default Logic

open access: yesStudia Universitatis Babes-Bolyai: Series Informatica, 2010
This paper presents a study of the nonmonotonic consequence relation which models the skeptical reasoning formalised by constrained default logic. The nonmonotonic skeptical consequence relation is defined using the sequent calculus axiomatic system.

Induction of Non-Monotonic Logic Programs to Explain Boosted Tree Models Using LIME

open access: yes, 2018
We present a heuristic based algorithm to induce \textit{nonmonotonic} logic programs that will explain the behavior of XGBoost trained classifiers.

Ambiguity Aversion, Portfolio Choice, and Life Expectancy

open access: yesInternational Economic Review, EarlyView.
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

A Nonmonotonic Sequent Calculus for Inferentialist Expressivists [PDF]

open access: yes, 2016
I am presenting a sequent calculus that extends a nonmonotonic consequence relation over an atomic language to a logically complex language. The system is in line with two guiding philosophical ideas: (i) logical inferentialism and (ii) logical ...

On cascade products of answer set programs

open access: yes, 2014
Describing complex objects by elementary ones is a common strategy in mathematics and science in general. In their seminal 1965 paper, Kenneth Krohn and John Rhodes showed that every finite deterministic automaton can be represented (or "emulated") by a ...
