A flexible framework for defeasible logics [PDF]

open access: yes, 2000
Logics for knowledge representation suffer from over-specialization: while each logic may provide an ideal representation formalism for some problems, it is less than optimal for others.

Embedding Defeasible Logic into Logic Programming

open access: yes, 2005
Defeasible reasoning is a simple but efficient approach to nonmonotonic reasoning that has recently attracted considerable interest and that has found various applications. Defeasible logic and its variants are an important family of defeasible reasoning

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 ...

How Does Progressivity Affect the Tax Cut Multiplier?

open access: yesInternational Economic Review, EarlyView.
ABSTRACT How does the targeting of personal income tax cuts affect the output multiplier? This paper provides quantitative evidence using a heterogeneous‐agent New‐Keynesian model calibrated to match US distributions of income, wealth, marginal tax rates, and marginal propensities to consume.

The Voting Premium

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT We develop a unified theory of blockholder governance and the voting premium in a setting without takeovers or controlling shareholders. A voting premium emerges when a minority blockholder can influence shareholder composition by accumulating votes and buying shares from dissenting shareholders.

Innovation and Structural Design in Regionalized Supply Networks

open access: yesJournal of Supply Chain Management, EarlyView.
ABSTRACT Regionalization is reshaping global supply networks (SNs) as firms respond to geopolitical, economic, and institutional pressures. Yet extant research has not examined how patterns of structural adaptation associated with regionalization may influence innovation. In this paper, we develop a typology of three theoretically grounded archetypes: (

Logical problems with nonmonotonicity

open access: yesLogic and Logical Philosophy, 2014
A few years ago, believing that human thinking is nonmonotonic, I tried to reconstruct a nonmonotonic reasoning by application of two monotonic procedures. I called them “step forward” and “step backward” (see [4]). The first procedure is just a consequence operation responsible for an extension of the set of beliefs.

Two‐Dimensional Reconfigurable Photodiode for In‐Sensor Color Filtering and Spectral Logic

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
By harnessing the photodoping of different aggregates, the device exhibits wavelength‐dependent volatile‐to‐nonvolatile photoresponses that can be reconfigured via bias modulation. This enables in‐sensor color filtering and spectral‐encrypted information processing, eliminating reliance on external optical filters or post‐processing algorithms ...

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

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 ...
