Models in Decision‐Making Under Risk and Uncertainty

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

Price Indices Rekindled, 1970s–1990s: Theory and Practice at Cross Purposes?

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper revisits the discussions on price indices during a period marked by theoretical advancements and practical challenges in measuring inflation. Index‐number theorists sought to improve accuracy, yet national statistical offices largely maintained established practices due to concerns over data availability, stability, and public trust.

Algebraic structures for transitive closure

Theoretical Computer Science, 1977
AbstractClosed semi-rings and the closure of matrices over closed semi-rings are defined and studied. Closed semi-rings are structures weaker than the structures studied by Conway [3] and Aho, Hopcroft and Ullman [1]. Examples of closed semi-rings and closure operations are given, including the case of semi-rings on which the closure of an element is ...

Journal of Management Studies, EarlyView.
Abstract The management literature often overlooks how firms can alter the competitive landscape without introducing groundbreaking changes or innovations. Applying the awareness, motivation, and capability framework from competitive dynamics, we posit that as a firm intensifies its product portfolio reconfiguration, its rivals become increasingly ...

Does Computer‐Assisted Surgery Improve the Accuracy of Immediate Implant Placement? A Systematic Review and Network Meta‐Analysis

Journal of Periodontal Research, EarlyView.
Computer‐assisted implant surgery (CAIS) enhances accuracy in immediate implant placement (IIP) compared to freehand, with no significant difference between CAIS techniques. The flapless technique is mainly used in IIP, reducing invasiveness and treatment time.
