Fundamental references from the Western culture

This article presents theoretical elements concerning the ‘nature versus culture’ confrontation as a particular aspect of the worldwide expansion of Western civilization. Several speculations are made concerning the philosophical foundations which have provided the base for the current political and economic mega-scenarios in the contemporary world. We turn our attention to the articulations of the concept of nature with the processes of mondialization of Western culture and with the history of universal culture. Finally, several considerations are made on the dynamics of economic processes on a world scale and projections on the impact of science and technology in the social and political frames that are taking place in the contemporary world.     

Does digitization lead to the homogenization of cultural content?

Using weekly music charts data in 10 countries over the period 1990–2015, we analyze whether digitization leads to a trend of homogenization of music content or conversely to a greater acoustic disparity. We split the digitization era in four periods that correspond to four new emblematic distribution models (Napster, iTunes, YouTube, Spotify). Our main result is that while acoustic diversity decreased during the iTunes and the YouTube periods, the period that begins with the introduction of audio streaming services, such as Spotify, represents a turning point and is marked by a significant increase in acoustic diversity.     

The weight of the rich: improving surveys using tax data

The Journal of Economic Inequality - Household surveys often fail to capture the top tail of income and wealth distributions, as evidenced by studies based on tax data. Yet to date there is no...     

The uncovered set in spatial voting games

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set.     

Sensing the skin: acne sufferers and the dermatologization of life

ABSTRACT

In this paper, we explore what we call the “dermatologization of life” and how it regulates the ways in which acne sufferers relate to their skin. We refer to these ways of relating to the skin as “skin sensing”. Through an analysis of the online narratives found on the website acne.org, we demonstrate how the skin sensing bound up with dermatologization both converges with and diverges from biomedical understandings of acne in three key contexts: the hormonal, the alimentary and the nocturnal. In doing so, we show that skin sensing involves a complex combination of pleasure and pain, excitement and exhaustion, and work and play. Ultimately, we suggest that the ways in which acne sufferers sense their skin open up a set of possibilities that not only disable but also enable them as they embark on the often all-consuming quest for a clear complexion.     

Consumer racial discrimination: A reassessment of the market for baseball cards

Research on the presence of consumer racial discrimination in the baseball labor and memorabilia markets has produced contradictory empirical results. While studies of baseball salaries find no evidence of discrimination, Nardinelli and Simon (1990) and Andersen and La Croix (1991) use data from the baseball card market to show that the price that consumers pay for a card depends on the player’s race. In this paper, we reconsider the evidence of consumer discrimination in the baseball card market. Our study improves on previous research by applying more appropriate econometric methods and using a data set in which card supply is constant and incentives for speculative demand are weaker. In contradiction to the aforementioned studies, we find little evidence of racial discrimination. This result proves robust across variable specifications and econometric models.

Backward Induction Is Not Robust: The Parity Problem and the Uncertainty Problem

A cornerstone of game theory is backward induction, whereby players reason backward from the end of a game in extensive form to the beginning in order to determine what choices are rational at each stage of play. Truels, or three-person duels, are used to illustrate how the outcome can depend on (1) the evenness/oddness of the number of rounds (the parity problem) and (2) uncertainty about the endpoint of the game (the uncertainty problem). Since there is no known endpoint in the latter case, an extension of the idea of backward induction is used to determine the possible outcomes. The parity problem highlights the lack of robustness of backward induction, but it poses no conflict between foundational principles. On the other hand, two conflicting views of the future underlie the uncertainty problem, depending on whether the number of rounds is bounded (the players invariably shoot from the start) or unbounded (they may all cooperate and never shoot, despite the fact that the truel will end with certainty and therefore be effectively bounded). Some real-life examples, in which destructive behavior sometimes occurred and sometimes did not, are used to illustrate these differences, and some ethical implications of the analysis are discussed.
