Montée en qualification et modification de la répartition au sein de la chaîne de valeur mondiale du secteur de l’électronique

Le secteur de l’électronique repose sur une chaîne de production mondiale particulièrement complexe. Les auteurs s'appuient sur des données de la base WIOD pour la période 2000–2014 afin d'apprécier la contribution des pays à cette chaîne de valeur. Ils examinent notamment l'incidence de la crise financière mondiale de 2007–2008 sur son évolution et établissent une cartographie des interactions internationales. L’étude révèle une augmentation des délocalisations depuis la crise financière, la Chine et d'autres pays d'Asie de l'Est étant devenus les principaux pôles de création de valeur. Elle montre aussi que les technologies de production ont connu une transformation radicale, accompagnée d'une montée en qualification.     

Sociodemographic characteristics of gay and lesbian victims of intimate partner psychological abuse in Spain and Latin America / Características sociodemográficas de gais y lesbianas víctimas de abuso psicológico en pareja en España e Hispanoamérica

Psychological abuse in same-sex couples has hardly been studied in Spain and Latin America, despite its importance in society and public health. The objective of this study is to examine the prevalence of psychological abuse in same-sex couples in Spain and Latin America and analyse the associated sociodemographic characteristics. An online survey was conducted with 663 gay and lesbian respondents from Spain and Latin America. Of the total sample, 10.6% reported that they perceived themselves as victims of psychological abuse from their partner (9.6% in gay men and 10.7% in lesbians). In gay men, differences were found between victims and non-victims on the sociodemographic variables of age, professional status, and daily alcohol consumption. In lesbians, significant differences were found between victims and non-victims in the country and professional status variables. When comparing gay and lesbian victims, significant differences were found in professional status and alcohol consumption. This study contributes to better understanding of this phenomenon, and it reveals the need for further research.     

Measuring the adoption of innovation. A typology of EU countries based on the Innovation Survey

Based on the Community Innovation Survey, this paper suggests new indicators of innovation adoption. The magnitude of innovation adoption is assessed for 22 EU countries and different industries. The most striking feature is the correlation between the innovation activities and the adoption rate. Countries with strong R&D and human resources and high innovation output exhibit the highest adoption rates. This supports the idea that innovation adoption requires an absorption capability. In addition, the specificities of each country regarding the prevailing types of innovation and adoption (product or process, cooperation-based adoption or internal adoption) allow us to draw up a typology of the EU countries, for which a specific geographical pattern is observed.     

Variance reduction in the study of a test concerning the behrens-fisher problem

A simulation case study illustrating the implementation of a variance reduction technique appropriate for dichotomous response variables is presented. In this simulation study, concerning the power of the Cochran and Cox test for the equality of means under possibly unequal variances, variance reductions of around 80% or more are obtained. More importantly, a known property of the Cochran and Cox, its conservative character, is detected thanks to the use of variance reduction.     

The effect of variability and carryover on average bioequivalence assessment: a simulation study

The purpose of this study was to evaluate the effect of residual variability and carryover on average bioequivalence (ABE) studies performed under a 22 crossover design. ABE is usually assessed by means of the confidence interval inclusion principle. Here, the interval under consideration was the standard 'shortest' interval, which is the mainstream approach in practice. The evaluation was performed by means of a simulation study under different combinations of carryover and residual variability besides of formulation effect and sample size. The evaluation was made in terms of percentage of ABE declaration, coverage and interval precision. As is well known, high levels of variability distort the ABE procedures, particularly its type II error control (i.e. high variabilities make difficult to declare bioequivalence when it holds). The effect of carryover is modulated by variability and is especially disturbing for the type I error control. In the presence of carryover, the risk of erroneously declaring bioequivalence may become high, especially for low variabilities and large sample sizes. We end up with some hints concerning the controversy about pretesting for carryover before performing ABE analysis.     

The Institutional vs. the Academic Definition of the Quality of Work Life. What is the Focus of the European Commission?

In recent years, we have seen how the quality of work life has been focused and defined by the European Commission (EC). In our study we compare the EC definition with the academic one and try to see how close they are. We also analyse the possibility of applying the institutional definition to the Spanish case through the development of specific indicators. Our main conclusions are that QWL is increasingly important for policy makers. In addition, it is essential to have objective indicators and to conduct surveys in order to reliably measure QWL.     

Migratory flows and pandemic: An analysis of impacts on immigrants of foreign origin in Spain

Restrictions on mobility as a measure to contain the COVID-19 pandemic meant, in the case of Spain, an abrupt ending to what could be called the second international migratory boom. At the same time, internal migrations underwent considerable change, with cities becoming less attractive as a destination for migrants, and increased flows into rural areas. In this context, our aim is twofold. First, it is to describe and analyse the decline in international migration according to origin and, second, to analyse internal migration among the population of immigrant origin. The results point to a temporary steep downturn in international flows, which does not affect all origins equally. In the case of internal migrations, there is a slight reduction in the intensity of movements with patterns similar to those of the autochthonous population. However, this drop in numbers is very significant among Asians and barely noticeable among immigrants from Latin America.     

Constituents of Quality of Life and Urban Size

Do cities have an optimal size? In seeking to answer this question, various theories, including Optimal City Size Theory, the supply-oriented dynamic approach and the city network paradigm, have been forwarded that considered a city’s population size as a determinant of location costs and benefits. However, the generalised growth in wealth that has been experienced over the last 50 years in developed countries has changed what have traditionally been seen as man’s needs. Thus, Inglehart’s post-materialist approach and Maslow’s theory of human needs force us to re-examine the traditional costs and benefits of cities. Here, we assume that costs and benefits enter the utility function of households through the quality of life concept. The relation between the constituents of quality of life and traditional and new theories of city size are considered here. Finally, we test these relations empirically in a specific dynamic, local framework: the city of Barcelona (Spain) in the period 1991–2000.     

LET'S TALK: HOW COMMUNICATION AFFECTS CONTRACT DESIGN

We study experimentally how communication changes the effectiveness of contract types when sellers choose unenforceable quality after a possible cost shock. Communication potentially removes conflicting perceptions that may otherwise plague flexible contracts. Indeed, we find that introducing free‐form communication sharply reverses an advantage of rigid contracts in favor of flexible contracts, which then deliver much higher earnings. Control treatments that avoid selection effects reveal a strong parallel shift from rigid to flexible. Chat content analysis identifies clarification of post‐shock transfers, promises, and personal rapport as key correlates of high earnings, with clarification working only in conjunction with flexible contracts. A communication channel restricted to clarifying transfer plans also favors use of flexible contracts, but mildly compared to chat. (JEL: C91, D03, D86)
