UNDER PRESSURE: GENDER DIFFERENCES IN OUTPUT QUALITY AND QUANTITY UNDER COMPETITION AND TIME CONSTRAINTS

Gender gaps in the workplace are widespread. One explanation for gender inequality stems from the effects of the interaction between competition and two pressure sources, namely, task stereotypes and time constraints. This study uses a laboratory experiment to find that the gender gap in performance under competition and preferences for competition can be partly explained by the differential responses of men and women to the above pressures. In particular, while women underperform the men in a high‐pressure math‐based tournament, women greatly increase their performance levels and their willingness to compete in a low‐pressure verbal environment, such that they actually surpass the men. This effect appears largely due to the fact that extra time in a verbal competition improves the quality of women’s work, reducing their mistake share. On the other hand, men use this extra time to increase only the quantity of work, which results in a greater relative number of mistakes. A labor market study suggests that the nature of the job and the stress level are correlated with the gender gap in the labor market in a manner consistent with the results of my experiment.

Symbols of Terror: ‘9/11’ as the Word of the Thing and the Thing of the Word

This paper adopts a social representations approach to examine the ‘9/11’ symbol which is argued to be a centrally organising, communication oriented, symbolic resource within contemporary representations of terrorism. Within the context of the events of September 11 2001 as a point of shared history which has come to be understood as a significant world event (Liu et al., 2009 ), the ‘9/11’ symbol is argued to fulfil a triple function in contemporary representations of terrorism. Firstly, the ‘9/11’ symbol provides a central anchor for the events of September 11 2001. Secondly the ‘9/11’ symbol acts as a powerful rhetorical resource for objectifying the abstract concept of terrorism. Lastly, alongside the capacity to objectify the abstract, the ‘9/11’ symbol also enables a counter process of transcendentalisation (Billig, 1988 ) whereby it transforms the object into the abstract. As a result the ‘9/11’ symbol is highly suited to widespread mobilisation of easily apprehended notions defining what terrorism is, which do not readily provoke contest and are widely constructed as mundane forms of ‘truth’ amongst a community of users.     

The interaction of pillars in multi‐pillar pension systems: A comparison of Canada,Denmark, Netherlands and Sweden

Canada, Denmark, the Netherlands and Sweden have advanced multi‐pillar pension systems. Using micro‐simulations, this article presents a close examination of the interaction of pillars in these countries. The relative importance and the role of the different pension pillars vary from country to country, and according to age, income, gender and socio‐economic dimensions as well as between generations. A further area of investigation is the mitigation capacity of the four pension systems. On the one hand, adverse labour careers lead to lower life‐time earnings and lower private pension accruals. On the other hand, these effects are mitigated through the design of pillars and their interaction. Mitigation is important to income security and stability in retirement and to post‐retirement income distribution. However, mitigation mechanisms come at the cost of incentives. Moreover, in many countries, the generosity of public benefits is set to decrease – increasing the importance of private pensions. This will shift risk and uncertainty from employers and pension institutions to individuals. Thus, risks and uncertainties related to private pensions will become more important, raising questions about the division of responsibilities between public and private pensions, and about the potential of mitigating such risk through pillar interaction. These concerns are further reinforced by labour market changes. Although a pension system free of distortions is inconceivable, this article seeks to contribute to addressing how mitigation should be designed, and how mitigation and risk sharing should be balanced against incentives, challenges which are as much political as technical.     

Nepal's Child Grant: A mixed‐methods assessment of implementation bottlenecks

This article evaluates the implementation of the Child Grant, one of the major social protection interventions in Nepal, and identifies bottlenecks that limit its ultimate effectiveness. On the whole, while delivery works for many beneficiaries, we found inconsistencies between the way the policy is laid out on paper, and the way it is actually implemented. Targeting efficiency is high, despite the wealth targeting criterion not being applied in practice. Owing to informal awareness‐raising campaigns, beneficiaries’ knowledge on registration, eligibility and entitlement is patchy. Payment levels vary and tend to be infrequent. These implementation bottlenecks limit the Grant's effectiveness and temper some of its impact potential.     

Extending maternity protection to all women: Trends,challenges and opportunities

Protecting maternity at work has been one of the primary concerns of the International Labour Organization since its foundation in 1919. Along with fundamental human rights treaties, the adoption of the Maternity Protection Convention, 2000 (No. 183) and, more recently, the ILO Recommendation concerning National Floors of Social Protection, 2012 (No. 202), have marked the universalization of the right to maternity protection and call for its extension to all women in line with the principle of equal opportunity and treatment between women and men. In the framework of these historical developments, this article presents evidence of how national legislative provisions on paid maternity leave have improved in the light of the principles of international labour standards, although a large majority of women workers are still not adequately protected in case of maternity. The article then addresses patterns of exclusion from maternity protection in law and practice, and concludes by discussing some social protection programmes that have the potential to extend maternity protection coverage and support to meet the care needs of the most vulnerable and which do so with a gender transformative focus.     

Financing social security out of contributions: About origins,present discussions and prospects of a success story

In writing the overture to an issue on contribution financed social security one cannot but speak of Bismarck; it must also address Beveridge who saw contributions, although in their design and role clearly differently from Bismarck, as one core revenue tool to finance his vision. Beveridge attributed to the private financial sector a prominent role in securing people against the negative effects on income of shocks and crises, while Bismarck did not. Beveridge's concept, when first published, had, and still has today, the most attractive charm of rigorously satisfying peoples' striving for equitable and inclusive societal solutions. Bismarck's concept intrinsically offers income security only to those who contribute, while the level of protection depends on the level of contributions paid (with the exception of health insurance). In reality, both concepts, where implemented, had to face the realities of socio‐economic and political developments: Beveridge's vision was achieved in respect of access to health services where his proposal, in its predominantly tax‐financed version, has since turned into a worldwide blueprint for health schemes; in its other components, it was not resilient enough to achieve the intended standards and now is replete with means‐tested (poor relief) elements. Bismarck's scheme has proven its potential to achieve “universality”, not necessarily by theoretical design but as a matter of fact, i.e. covering people from cradle to grave (like Beveridgean schemes). With globalization, schemes of both origins have had to face massive neoliberal attacks over the last three decades. Which of the approaches is best able to survive must be left an open question: in the current worldwide context of rapid change, both have weak and strong points, and whether a symbiosis of the two offers the answer to future challenges remains to be seen.     

Little cash to large households: Cash transfers and children's care in disadvantaged families in Ghana

Social protection is widely considered to have a positive effect on children, including supporting improvements in nutritional, educational and health outcomes. Much less is known, however, about the impact of interventions on children's care. This article considers the impact of a social cash transfer targeted at poor households – Ghana's Livelihood Empowerment Against Poverty (LEAP) programme – on child well‐being, quality of care and preventing children's separation from their parents as perceived by programme and non‐programme beneficiaries in a context of vulnerability, large households and widespread informal kinship care. Findings suggest that cash transfers can improve both material and non‐material aspects of well‐being and contribute to the quality of care and have the potential to prevent children's separation from their parents. At the same time, not all children appear to benefit equally, with non‐biological children being disadvantaged. The combination of large household sizes with programme design and implementation challenges, including low transfer amounts, a cap on the maximum number of eligible household members and poor sensitization and follow‐up, undermine the positive role that cash transfers can play.     

A multifactorial explanation of youth unemployment and the special case of Austria

One of the biggest challenges currently facing European society is the dramatically high level of youth unemployment. Commonly, political solutions and strategies can be found in those countries that have been able to keep youth unemployment low in spite of the financial and economic crises. Austria is such a case. On the basis of European Union Member State data, the article gives a multifactorial explanation of youth unemployment and asks whether these factors can explain relatively low youth unemployment in Austria. With the country's “youth safety net” presented in detail, it is shown that active labour market policy reduces youth unemployment in Austria. The article also points out the limitations of cross‐country comparisons of youth unemployment rates and proposes the use of a greater number of indicators. Finally, the article argues for economic policies to stimulate demand, which have to be based on a political and social commitment to full employment.     

Rényi statistics for testing equality of autocorrelation coefficients

The problem of testing for equality of autocorrelation coefficients of two populations in multivariate data when errors are autocorrelated is considered. We derive Rényi statistics defined as divergences between unrestricted and restricted estimated joint probability density functions and we show that they are asymptotically chi-square distributed under the null hypothesis of interest. Monte Carlo simulation experiments are carried out to investigate the behavior of Rényi statistics and to make comparisons with test statistics based on the approach of Bhandary [M. Bhandary, Test for equality of autocorrelation coefficients for two populations in multivariate data when the errors are autocorrelated, Statistics & Probability Letters 73 (2005) 333–342] for the problem under consideration. Rényi statistics showed to have significantly better behavior.
