“…In fact, as Mealy et al (2018) have very recently noted, the method of reflections belongs in the family of spectral clustering algorithms for partitioning similarity matrices, and can therefore be thought of as a complement to recently proposed methods to study the structure of cultural choices that exploit relational information embedded in survey responses. These include relational class analysis (Goldberg, 2011), correlational class analysis (Boutyline, 2017), and belief-network analysis (Boutyline and Vaisey, 2017) among others.…”

“…As a result, the eigenvector rank will be strongly dependent on the first order centrality of both people (omnivorousness) and genres (popularity), while the reflective equilibrium rank can be shown to be orthogonal to, although typically correlated with, the first order centralities of each mode. In this respect, the eigenvector centrality score does not add much information beyond first order omnivorousness and popularity with the correlation between these two quantities being to 1.0, while the correlation between eigenvector and the equilibrium reflective centrality rank between much lower (see Mealy et al, 2018, , Figure 2). 4 As such, reflective centrality is picking up something different from the eigenvector idea both conceptually and empirically.…”

“…In fact, this is an issue that has already come up in the literature, with some arguing that a reflective strategy is an algorithm for calculating a version of eigenvector centrality (Morrison et al, 2017). However, as Mealy et al (2018) note in a recent contribution. This interpretation, while intuitive, is not on the right track.…”

The mutual specification of genres and audiences: Reflective two-mode centralities in person-to-culture data

Recent developments at the intersection of cultural sociology and network theory suggest that the relations between persons and the cultural forms they consume can be productively analyzed using conceptual resources and methods adapted from network analysis. In this paper, I seek to contribute to this developing line of thinking on the culture-networks link as it pertains to the sociology of taste. I present a general analytic and measurement framework useful for rethinking traditional survey (or population) based data on individuals and their cultural choices as a two mode persons × genres network. The proposed methodological tools allow me to develop a set of "reflective" metrics useful for ranking both persons and genres in terms of the pattern of choices and audience composition embedded in the cultural network. The empirical analysis shows that these metrics have both face and criterion validity, allowing us to extract useful information that would remain out of reach of standard quantitative strategies. I close by outlining the analytic and substantive implications of the approach.

“…Notice, however, that the rows ofM sum to one (which also means that a vector of all ones is an eigenvector ofM and it is associated with the largest eigenvalue ofM) and so, the vector associated to the second largest eigenvalue ofM is taken as the industry complexity (C i ). For more details on the calculation and interpretation of the industry complexity see Hausmann et al (2014c) and Mealy et al (2018).…”

Commuting times and the mobilisation of skills in emergent cities

Labour mobility within a large city or metropolitan area is a necessary condition for the optimal exploitation of agglomeration economies. We propose a method to establish which municipalities should be considered part of a metropolitan area based on labour market integration. In order to aggregate geographically proximate urban municipalities, we develop a network-based model that makes industry productivity (manifesting in formal employment creation) dependent on firms' ability to find, within city limits, the diversity of skills they need to move to new complex industries. In this way, we uncover the natural city scale at which firms optimally exploit the range of skills available to them within a broad catchment area. Considering Colombian cities, we find that commuting times between 45 and 75 min, corresponding to between 43 and 62 distinct cities or integrated labour markets, allow firms to maximise formal employment creation (between 2008 and 2013). This result supports the development of passenger transport limiting commuting times within cities, connecting small-and mid-size cities to nearby large cities, and coordinating transportation investments across traditional administrative boundaries.

“…Thus, the ECI builds upon productive diversification 3 and capabilities. As discussed by Mealy et al (2018) There is ample evidence on the relationship between diversification and economic growth, especially for less developed countries (Cherif, et al, 2018;Al-Marhubi, 2000;Herzer and Nowak-Lehnmann, 2006 countries are competitive in. Furthermore, the ECI provides a rank ordering of countries in terms of how similar their exports and capabilities are to each other and this ordering helps to explain variations in GDP per capita and future growth (Hidalgo and Hausmann, 2009).…”

The Addis Ababa Action Agenda of the Third Conference on Financing for Development underscores sustainable and resilient infrastructure as a pre-requisite to sustainable development. Public-Private Partnerships (PPPs) are expected to deliver infrastructure in furtherance of this Agenda. In view of this expectation, twelve prominent PPP guidelines were reviewed for alignment with the Addis Agenda and key public governance factors. The research found that the PPP guidelines are not sufficiently aligned with the Addis Agenda, have insufficient sustainability content, and do not acknowledge the role of the public in PPPs. It recommends that the next generation of the guidelines address these aspects.
