Characterizations based on order statistics under sampling without replacement

In this paper, we consider finite populations and investigate their characterizations by regressions of order statistics under sampling without replacement. We also investigate some asymptotic results when the size of the population goes to infinity.     

Parents’ income and children’s school drop-out at 16 in England and Wales: evidence from the 1970 British Cohort Study

This paper investigates the effect of parents’ income on children’s drop-out from school at age 16 using data from the 1970 British Cohort Study (BCS70). Unlike previous papers using the same data set, we use a continuous measure of income derived from the grouped income variable available in the BCS70, we employ instrumental variable techniques to address the issue of endogeneity of family income and take account of the potential endogeneity of income response with respect to a child’s education by jointly modelling the school drop-out decision and response to the family income question. Our estimates show the exogeneity of response to the income question with a child’s education and are in line with the previous literature finding a statistically significant small negative effect of family income on school drop-out at 16. On the contrary, other non-pecuniary parental effects, such as parental education and social class, turn out to be both significant and of a sizeable magnitude. Early versions of this paper benefited from presentations at the University of Warwick, the ZEW Summer Workshop 2002 on Human Capital, the European Society for Population Economics 2002 Conference and the European Economic Association 2002 Conference and comments by Martin Andrews, Lorenzo Cappellari, Charlotte Lauer, Derek Leslie, Jeremy Smith, Mark Stewart, and two anonymous referees.

Approximation of the distribution of excesses through a generalized probability-weighted moments method

The POT (peaks-over-threshold) approach consists in using the generalized Pareto distribution (GPD) to approximate the distribution of excesses over a threshold. In this paper, we consider this approximation using a generalized probability-weighted moments (GPWM) method. We study the asymptotic behaviour of our new estimators and also the functional bias of the GPD as an estimate of the distribution function of the excesses. A simulation study is provided in order to appreciate the efficiency of our approach.     

Inference about permutation parameter in large samples

The estimation problem of a permutation parameter on the basis of a random sample of increasing size is considered. A necessary and sufficient condition for the existence of an estimator, asymptotically fully efficient for two different distributions families, is derived. We also study the application of this result to cyclic groups of order two and three.     

论“70后”诗歌中的城市空间

"70后"诗歌文本中凝聚了诸多诗人对城市情境采撷、勾勒乃至描绘的共性视线交集,诗人多以当代都市为触媒,探询深藏于城乡文化之间的个体经验。一些诗人以怀念"文化乡土"的姿态,抒写对城市文化经验的不适应感,对其带给现代人的诸多束缚和制约进行揭露与批判;还有一类诗人能够放松心态,将城市视为文化母体和诗意诞生的源泉,在"物欲"和"孤独"的日常性主题中纵情诗意,捕捉凡俗生活中的瞬间心理经验,走向真正意义上的"个人化写作"。     

70年中国新闻史研究述略

中华人民共和国成立70年来,与政治制度变革和政治路线变迁相顺应,前30年的新闻史研究,“革命史范式”占据主导地位,研究队伍人数较少,研究对象局限于无产阶级新闻事业。后40年的新闻史研究,新闻史的学科地位确立,汲取传播学及其他学科理论与方法,“新闻本体范式”兴起,研究范式多样化,中国新闻史学会成立,学术队伍人才济济,学术成果丰硕并走向世界。此后的新闻史研究,须更多负起“资治”“知来”之责,创新研究范式,填补研究空缺,建设中国特色新闻史学。     

China's energy inefficiency: A cross-country comparison

This paper constructs a total-factor energy technical efficiency index using the data envelopment analysis (DEA) method following the total factor productivity framework. We then compare energy technical efficiency across 156 countries from 1980 to 2007. The results show that China's energy efficiency considerably trails other countries’ although it has made significant gains within the last 28 years. Further analysis indicates that scale inefficiency rather than pure technical efficiency contributes to China's energy inefficiency.     

BOOK TRANSLATIONS AS IDEA FLOWS: THE EFFECTS OF THE COLLAPSE OF COMMUNISM ON THE DIFFUSION OF KNOWLEDGE

We use book translations as a new measure of international idea flows and study the effects of Communism's collapse in Eastern Europe on these flows. Using novel data on 800,000 translations and difference‐in‐differences approaches, we show that while translations between Communist languages decreased by two thirds with the collapse, Western‐to‐Communist translations increased by a factor of 4 and quickly converged to Western levels. Convergence was more pronounced in the fields of applied and social sciences, and was more complete in Satellite and Baltic than in Soviet countries. We discuss how these patterns help us understand how repressive institutions and preferences towards Western European ideas shaped the international diffusion of knowledge.     

Multinationals’ political activity for institutional change: Evidence from Spain during the international crisis of 2008

International crises generate uncoupling between multinational enterprises (MNEs) and the institutional environment. In these settings, industry associations of MNEs have an incentive to engage in institutional change by taking a role as institutional entrepreneurs in order to generate change within the existing, unsuitable institutions. However, MNEs can also try to avoid such institutions or try to adapt to them. Because the antecedents and outcomes of these three forms of engagement in institutional change (institutional avoidance, adaptation, and entrepreneurship) have been scarcely studied in Europe, this reflection examines the case of Spain during the international crisis and analyses the coordinated action of MNEs through their associations in seven industries. The discussion of 30 pieces of evidence regarding the engagement in institutional change in Spain suggests a model that proposes relevant antecedents of different forms of engagement and the expected outcomes resulting from the chosen forms, among them: co-evolution and co-involution.     

Truncated sequential change-point detection based on renewal counting processes II

The standard approach in change-point theory is to base the statistical analysis on a sample of fixed size. Alternatively, one observes some random phenomenon sequentially and takes action as soon as one observes some statistically significant deviation from the “normal” behaviour. The present paper is a continuation of Gut and Steinebach [2002. Truncated sequential change-point detection based on renewal counting processes. Scand. J. Statist. 29, 693–719] the main point being that here we look in more detail into the behaviour of the relevant stopping times, in particular the time it takes from the actual change-point until the change is detected, more precisely, we prove asymptotics for stopping times under alternatives.
