ACE Research Vignette 045: Are “Entrepreneurial Opportunities” a meaningful topic for entrepreneurship research?

This series of research vignettes is aimed at sharing current and interesting research findings from our team of international entrepreneurship researchers. In this vignette, Professor Per Davidsson discusses research on “entrepreneurial opportunities”. A “Government Health Warning” is in place for this particular vignette: it mainly concerns matters internal to entrepreneurship research; however, reflective practitioners may find it to be of interest.

A preference-based semantics for CTD reasoning

In [8] the authors developed a logical system based on the definition of a new non-classical connective ⊗ capturing the notion of reparative obligation. The system proved to be appropriate for handling well-known contrary-to-duty paradoxes but no model-theoretic semantics was presented. In this paper we fill the gap and define a suitable possible-world semantics for the system for which we can prove soundness and completeness. The semantics is a preference-based non-normal one extending and generalizing semantics for classical modal logics.
