Managerial Delegation under Alternative Unionization Structures

This paper studies the effects of managerial delegation in a duopoly game under alternative unionization structures. Introducing managerial delegation in a framework with centralized unionization leads to incentives for sales, lower profits and higher consumer surplus as well as overall welfare. In contrast, delegating output decisions to managers in the presence of decentralized unionization produces opposite results unless unions are strongly employment‐oriented. Moreover, managerial delegation makes unionization structure neutral in relation to consumer surplus and overall efficiency. Finally, the timing of moves in the three‐stage game proves to be important for obtaining the above qualitative results under decentralized unionization.     

Asymptotic Properties and Variance Estimators of the M-quantile Regression Coefficients Estimators

M-quantile regression is defined as a “quantile-like” generalization of robust regression based on influence functions. This article outlines asymptotic properties for the M-quantile regression coefficients estimators in the case of i.i.d. data with stochastic regressors, paying attention to adjustments due to the first-step scale estimation. A variance estimator of the M-quantile regression coefficients based on the sandwich approach is proposed. Empirical results show that this estimator appears to perform well under different simulated scenarios. The sandwich estimator is applied in the small area estimation context for the estimation of the mean squared error of an estimator for the small area means. The results obtained improve previous findings, especially in the case of heteroskedastic data.     

Women migrants in the global economy: a global overview (and regional perspectives)

ABSTRACT

Huge advances have been made in deepening and expanding our knowledge of gendered migration over the last decades in both theoretical and methodological terms. Empirically it is, however, still the case that North–South migration is at the basis of most theorisations, leaving the characteristics of South–South migration at the margins. In this paper we, therefore, shift the focus to intra- and trans-regional migration in a South–South context in exploring what this means for women migrants. While feminist scholars have highlighted care and the ways in which migration challenges social reproduction as an important issue, mainstream approaches continue to focus predominantly on the ‘productive’ lives of migrant workers. With migration theories still largely drawing on the experience of South–North migration, there continues to be relatively little understanding of South–South migration’s gender dynamics, despite the fact that many of the highly feminised, yet hyper-precarious, migration flows occur intra-regionally.     

The unequal impact of Covid-19 on the lives and rights of the children of modern slavery survivors,children in exploitation and children at risk of entering exploitation

This article discusses the unequal impact of Covid-19 on the lives of the children of survivors of modern slavery, child victims of exploitation and children at risk of exploitation in the UK. It draws on research that has analysed the risks and impacts of Covid-19 on victims and survivors of modern slavery. It explores how pandemic responses may have hindered these children's rights to education, food, safety, development and participation and representation in legal processes. It suggests that the pandemic should be used as an impetus to address inequalities that existed pre-Covid-19 and those that have been exacerbated by it.     

Small area estimation: the EBLUP estimator based on spatially correlated random area effects

This paper deals with small area indirect estimators under area level random effect models when only area level data are available and the random effects are correlated. The performance of the Spatial Empirical Best Linear Unbiased Predictor (SEBLUP) is explored with a Monte Carlo simulation study on lattice data and it is applied to the results of the sample survey on Life Conditions in Tuscany (Italy). The mean squared error (MSE) problem is discussed illustrating the MSE estimator in comparison with the MSE of the empirical sampling distribution of SEBLUP estimator. A clear tendency in our empirical findings is that the introduction of spatially correlated random area effects reduce both the variance and the bias of the EBLUP estimator. Despite some residual bias, the coverage rate of our confidence intervals comes close to a nominal 95%.     

STRANGE YET STYLISH HEADGEAR VR consumption and the construction of gender

This article examines how gender is inscribed and reproduced in the consumption of Virtual Reality (VR) technologies. The focus is on how virtual reality systems become embedded in 'everyday life' through leisure and consumption, and how the spectacles and disciplines associated with consumption sites produce gendered virtual subjects. Studies of new communications technologies have tended to polarize between 'cyberpunk'/'cyberfeminist' visions of bodily transcendence in 'cyberspaces', and the critique of such visions from social theorists who focus on the reproduction of social and cultural inequalities through technical systems. These approaches tend to neglect the specific sites in which the social relations of VR are played out. A 'multi-sited' ethnographic study of immersive virtual reality systems is the basis for discussion of how virtual reality technologies produce gender in specific sites. Virtual systems are positioned and used differently in various locales such as arcades and art galleries, bars and theme parks and cafes. The article discusses the practices of consumption which (re)produce and maintain conventional bodily and subjective boundaries. What relationships are becoming institutionalized? Are new conventions of gender created in these consumption relationships? The construction of spectacle and space, and the specific bodily disciplines required for participation in virtual realities in locations of consumption is particularly important in the formation of gender dynamics. Multiple subject positions are offered through competing technical, economic and cultural practices in diverse sites. These positions can establish new conventions of virtual identities and experiences, but also remain shot through with familiar operational categories of gendered identities and bodily practices. This article argues that immersive virtual reality technologies cannot be understood without some consideration of the locales in which they are embedded, and the social identities they make possible or constrain. A local, reflexive and feminist orientation assists in understanding the gendered dynamics associated with 'becoming virtual'.
