A New Proposal to Gauge Intergenerational Mobility: Educational Mobility in Europe as a Case Study

This paper is aimed at presenting a new intergenerational mobility index that (a) combines the intergenerational elasticity and the R-squared of the intergenerational regression and (b) enables the expression of the total degree of mobility as the weighted sum of mobility with respect to both parents. As a case study, we apply our proposal to investigate the intergenerational mobility of education in several European countries and its changes across birth cohorts. The results derived from the proposed index indicate that Nordic countries display higher levels of educational mobility than Southern countries, whereas continental countries are in an intermediate position. Moreover, it appears that the degree of mobility increases over time only in those countries with low initial levels and remains stable for the most mobile countries. Finally, for most of the countries the proposed methodology can prove that the degree of educational mobility with respect to each parent tends to converge to the same level over the course of time.     

Ambiguity in the Small and in the Large

This paper considers local and global multiple‐prior representations of ambiguity for preferences that are (i) monotonic, (ii) Bernoullian, that is, admit an affine utility representation when restricted to constant acts, and (iii) locally Lipschitz continuous. We do not require either certainty independence or uncertainty aversion. We show that the set of priors identified by Ghirardato, Maccheroni, and Marinacci's (2004) “unambiguous preference” relation can be characterized as a union of Clarke differentials. We then introduce a behavioral notion of “locally better deviation” at an act and show that it characterizes the Clarke differential of the preference representation at that act. These results suggest that the priors identified by these preference statements are directly related to (local) optimizing behavior.

Homemaking in the public. On the scales and stakes of framing,feeling, and claiming extra-domestic space as “home”

This article reviews the emerging literature on the negotiation of home-related feelings, claims, and practices in the public urban sphere, under the rubric of homemaking in the public. This contributes to a better sociological understanding of home and illuminates long-debated societal questions such as the interaction between majority and minority groups and the shifting boundaries between what is (regarded as) public or private. While home has traditionally been understood as a private and domestic matter, it also has a major public significance. As a category of analysis, it reveals how supposedly domestic attitudes, routines, and practices are scaled up into the public domain. As a category of practice, it is a powerful discursive resource for contentious politics in the extra-domestic domain. Who is entitled and legitimated to claim a public space as “home”, and what this implies for inter-group categorizations and relations, are questions that deserve original and comparative analysis in sociology. Processes of domestication of the public sphere, of mutual interaction between public and private life realms, and of claims-making on various scales can be fruitfully revisited along these lines, by advancing an original research agenda on the ways of framing, feeling and claiming public space as home.     

Social media teams as digital vanguards: the question of leadership in the management of key Facebook and Twitter accounts of Occupy Wall Street,Indignados and UK Uncut

Recent protest movements such as Occupy Wall Street in the US, the indignados/15M movement in Spain, and UK Uncut have witnessed the rise of social media teams, small activist groups responsible for managing high-visibility and collective activist social media accounts. Going against dominant assertions about the leaderless character of contemporary digital movements, the article conceptualises social media teams as ‘digital vanguards’, collective and informal leadership structures that perform a role of direction of collective action through the use of digital communication. Various aspects of the internal functioning of vanguards are discussed: (a) their formation and composition; (b) processes of internal coordination; (c) struggles over the control of social media accounts. The article reveals the profound contradiction between the leadership role exercised by social media teams and the adherence of digital activists to techno-libertarian values of openness, horizontality, and leaderlessness. The espousal of these principles has run against the persistence of power and leadership dynamics leading to bitter conflicts within these teams that have hastened the decline of the movements they served. These problems call for a new conceptual framework to better render the nature of leadership in digital movements and for new political practices to better regulate the management of social media assets.     

MARKET DISTORTIONS AND GOVERNMENT TRANSPARENCY

In this paper, we investigate how government transparency depends on economic distortions. We first consider an abstract class of economies in which a benevolent policy maker is privately informed about the exogenous state of the economy and contemplates whether to release this information. Our key result is that distortions limit communication: even if transparency is ex ante Pareto superior to opaqueness, it cannot constitute an equilibrium when distortions are sufficiently high. We next confirm this broad insight in two applied contexts, in which monopoly power and income taxes are the specific sources of distortions.
