WebDec 13, 2024 · The problem is that the studies with firm-specific factors are inconclusive and often bring contradictory results. Taking size and age factors as an example, there is still no agreement about whether the age effect is an inverted U-shape and the size effect is nonlinear (see Strotmann, 2007 or Agarwal & Gort, 2002 as examples). Therefore, we ...

WebJun 1, 2016 · The Path-size model was proposed to deal with the overlap problem, while maintaining the computational simplicity of the logit form. As described in the first section, Path-size Logit model and C-logit model are both MNL-modifications and only account for the overlaps of routes within the deterministic part. WebMar 1, 2024 · The adaptive path-size logit (APSL) model, proposed by Duncan et al. (2024), is internally consistent in the sense that the adjustment factors for overlap are calculated based on route choice probabilities. Recently, the integration of path-size concepts, including the APSL, into the BCM have been explored by Duncan et al. (2024).
WebJan 1, 2008 · The new measure of path size offers a more natural interpretation of the correlation due to spatial overlap of alternative routes. Estimation of PSC-logit models in two real-world networks and calculation of predicted choice probabilities in synthetic networks allow comparison of the new path size measure with respect to the classic one.
