The Quality Adjusted Price Index in the Pure Characteristics Demand Model

This paper computes a quality adjusted price index for the personal computer CPU from 1996 to 2000. The index is based on the pure characteristics demand model. I first compute the quality adjusted price index for the whole market, and show that it is very comparable with the hedonic price index but more sensitive to changes in product quality. Two types of the hedonic index are considered. One is the dummy variable index and the other is the formulation in Pakes (2003). When I group consumers by their willingness to pay for attribute improvement, the index shows consumer groups are differently affected by their product choices.     

Tests of symmetry based on transformed empirical processes

A probability distribution function F is said to be symmetric when 1 ‐ F(x) ‐ F(‐x) = 0 for all x∈ R. Given a sequence of alternatives contiguous to a certain symmetric F₀, the authors are concerned with testing for the null hypothesis of symmetry. The proposed tests are consistent against any nonsymmetric alternative, and their power with respect to the given sequence can easily be optimized. The tests are constructed by means of transformed empirical processes with an adequate selection of the underlying isometry, and the optimum power is obtained by suitably choosing the score functions. The test statistics are very easy to compute and their asymptotic distributions are simple.     

Estimating the number of clusters

Hartigan (1975) defines the number q of clusters in a d ‐variate statistical population as the number of connected components of the set {f > c}, where f denotes the underlying density function on R^d and c is a given constant. Some usual cluster algorithms treat q as an input which must be given in advance. The authors propose a method for estimating this parameter which is based on the computation of the number of connected components of an estimate of {f > c}. This set estimator is constructed as a union of balls with centres at an appropriate subsample which is selected via a nonparametric density estimator of f. The asymptotic behaviour of the proposed method is analyzed. A simulation study and an example with real data are also included.     

The identity of memory and the memory of identity in the age of commodification and democratization

Abstract

This article explores the relationship between secularization and commodification of culture on one hand, and national identity always represented as Christian mystery on the other. Focusing on three case studies, Poland, Quebec and Zaire, the author analyses the place of an ordinary object (commodity) as a vehicle of representation of people's affirmation of belonging to a ‘nation’. He stresses the disposable nature of such an affirmation of belonging which allows everyone to alter or cast off the symbols of belonging while changing their social or political contexts.     

Personal identity versus national identity among Hong Kong youths – personal and social education reform after reunification

This paper examines the use of Chinese traditions for the formation of a felt Hong Kong identity and a national identity among students in the personal and social education curriculum before and after reunification with China in 1997. This paper argues that the addition of China elements to the curriculum after reunification contributes to the continuous ambiguous identity of students, which is consistent with the results of various poll surveys about the civic identity of Hong Kong people in a larger context. This is because the personal and social education reform after reunification assumed a simple correlation between the patriotic feelings of students and their knowledge of China. It does not question how the promotion of an intensely unifying ‘cultural identity’ as political commitment is differentiated from the day-to-day ‘cultural experiences’ of students.     

Will to love,will to fear: the emotional politics of illegality and citizenship in the campaign against birthright citizenship in the US

Anti-immigration activists argue that the broad inclusivity of the birthright citizenship clause of the 14th Amendment is a national security concern that enables criminalized migrant mothers to give birth to citizens who can later harm the US through violence and resource consumption. Seeing this argument as representative of the problem of inclusivity inherent to citizenship in a liberal democracy, this essay asks how the children of undocumented and temporary migrants are constructed as what Mae Ngai calls ‘alien citizens.’ Drawing from Sara Ahmed's affective economy of emotion, I find that affect and emotion figure prominently in how citizens are made ‘alien.’ Specifically love and fear function as pivot points in the anti-birthright citizenship argument, wherein the ‘real citizen’ is ‘willed’ to love and be loved by the nation and to fear the nation's Others. Moreover, the emphasis on national feelings does not evacuate white supremacy or heteronormativity from its imagination of citizenship, but instead displaces these loci of power into feeling and affect. Thus, this essay claims that the birthright citizenship argument illustrates how national love and fear work in tandem to uphold, naturalize, and expand the racial and sexual exclusions inherent to citizenship in a nation-state.     

Institutions,inculcation, and black racial identity: pigmentocracy vs. the rule of hypodescent

This research paper investigates the effect political institutions have on black racial identity. In particular, I study individual inculcation in contexts where political institutions institutionalize either of two forms of racial social structures – a pigmentocracy (the Dominican Republic), or the rule of hypodescent (the US South), and the effect such inculcation has on black racial identity. I sampled 101 respondents from the Dominican Republic and 102 from the state of Mississippi, USA. Consistent with the basic assumptions of my hypotheses, respondents in the Dominican Republic study sites showed a weaker degree of identification with blackness vis-à-vis something ‘whiter’. Nevertheless, respondents in the Dominican Republic sites demonstrated a stronger identification with blackness than what most conventional observers would have anticipated. Respondents in the Mississippi study sites showed a stronger sense of identification with blackness. Surprisingly, however, Mississippi respondents demonstrated a larger degree of neutrality than expected in their belief of being of a mixed racial heritage rather than just a black African heritage.     

Between Neo-liberalism and Neo-indigenismo: Reconstructing National Identity in Mexico

Heightened integration with the US coupled with the rise of an indigenous movement have challenged and strained long-held images regarding the US and the indigenous within Mexico. As a result, Mexico finds itself facing the difficult task of re-evaluating and reconstructing its national identity. This paper explores the traditional images of the US and the Indian shaping national identity in Mexico and the challenges posed today by neo-liberalism and neo-indigenismo. It sets out a range of current issues, explores the linkages and contradictions, and examines the state of national reform. Fundamentally, the paper strives to raise important theoretical questions and hence set the stage for further research into these issues.
