Sample Path Asymmetries in Non‐Gaussian Random Processes

We tackle an important although rarely addressed question of accounting for a variety of asymmetries frequently observed in stochastic temporal/spatial records. First, we review some measures intending to capture such asymmetries that have been introduced on various occasions in the past and then propose a family of measures that is motivated by Rice's formula for crossing level distributions of the slope. We utilize those asymmetry measures to demonstrate how a class of second‐order models built on the skewed Laplace distributions can account for sample path asymmetries. It is shown that these models are capable of mimicking not only distributional skewness but also more complex geometrical asymmetries in the sample path such as tilting, front‐back slope asymmetry and time irreversibility. Simple moment‐based estimation techniques are briefly discussed to allow direct application to modelling and fitting actual records.     

Developing countries and systemic pension reforms: Reflections on some emerging problems

Since 1981 close to forty countries have introduced systemic pension reforms that have replaced all or part of prior pay‐as‐you‐go (PAYG) schemes with privately managed funded defined contribution (FDC) pillars or systems. However, over the past decade about half of these countries have subsequently cutback on, or entirely eliminated, these FDC schemes. In this article we explore some of the reasons why this reversal is often taking place in developing countries. As part of our analysis we propose a new pension reform typology that goes beyond the commonly used dichotomy between PAYG and pension privatization. We identify and discuss four factors that are of particular relevance to those seeking to understand the pension policy reversals that have been taking place in many developing countries: low pension coverage and incentive incompatibility, triple burden costs, tradeoffs between pension reforms and social pensions, and difficulties with annuitization.     

Paid parental leave and other supports for parents with young children: The United States in international comparison

The United States is at a crossroads in its policies for families and women. Currently, the United States provides basic support for children, fathers, and mothers in the form of unpaid parental leave, child‐related tax breaks, and limited public child care. In contrast, the other member states of the Organisation for Economic Co‐operation and Development (OECD) empower families through paid parental leave and comprehensive investments in infants and children. The potential gains from strengthening these policies in the United States are enormous. Paid parental leave and subsidized child‐care help to get and keep more women in the workforce, contribute to economic growth, offer cognitive and health benefits to children, and give parents options in defining their preferred work‐life strategy. Indeed, the United States has been falling behind the rest of the OECD in many social and economic indicators by not adequately investing in children, fathers and mothers. Given the significant payoffs to these family supports, this article focuses on issues of reconciling work and care commitments for families with young children, and, in particular, on paid parental leave policies within the OECD and the United States.     

How portable is social security for migrant workers? A review of the literature

This article reviews the recent literature on existing mechanisms that allow for the portability of social security entitlements for migrant workers and finds that North–North migrants have the best access to portability. There is limited coordination between origin and destination countries regarding the portability of social entitlements of South–North migrants. These migrants are dealing with discourses and policies that treat them as second class citizens, even as they are providing much‐needed labour to their host countries. South–South migrants are seeing new regional mechanisms addressing portability. However, many of the impacts of these mechanisms are not yet known. Other knowledge gaps on portability relate to internal and South–South migration, the role of gender and other social identities, migrants’ occupations as well as their legal immigration status.     

Longevity insurance annuities: China adopts a benefit innovation from the past

Longevity insurance annuities are deferred annuities that begin payment at advanced older ages, such as at age 80. Such annuities would benefit some older retirees who have drawn down their savings, but the private sector has problems in providing them. Originally, social insurance old‐age benefits programmes in some countries were structured as longevity insurance programmes, with 50 per cent or less of those entering the workforce surviving to receive the benefits. Over time, however, as life expectancy has improved, the benefits these programmes provide have slowly transformed into benefits that most people entering the workforce ultimately receive. This article argues that the reintroduction of longevity insurance benefits as part of social insurance old‐age benefit programmes could be an important policy innovation, in particular because this benefit is generally not provided by the private sector. China has introduced longevity insurance benefits as part of its social insurance system, offering a model for other countries, particularly those providing modest social insurance old‐age benefits.     

Social health insurance development in Mongolia: Opportunities and challenges in moving towards Universal Health Coverage

Mongolia achieved high population coverage under mandatory health insurance relatively quickly. This fact was viewed by policy‐ and decision‐makers as a central issue for health financing reform in Mongolia. Health insurance brought many new features for health service planning, provision, funding and resource management. Based on initial achievements, health insurance came to be strategically considered as the vehicle for achieving universal coverage. The article analyses developments in Mongolia's health insurance over the last decade along with the core policy dimensions of Universal Health Coverage. It examines various reform approaches and the numerous amendments to laws that have been implemented during this period and discusses new opportunities as well as challenges. The analytical review and findings discussed suggest that Mongolia has a need for evidence‐based policy decisions and informed political support, with health insurance backed by robust institutional and administrative capacities. More generally, it also emphasizes that health policy goals and objectives can be attained by strengthening and making transparent and publicly‐accountable all health system financing functions and arrangements. The policy analysis, experiences, lessons and proposed strategies presented with regard to Mongolia intend to stimulate wider discussions on health insurance development as well as promote continuing focused research on specific aspects of health insurance and public financing reform.     

Disability benefit reform in Great Britain from the perspective of the United States

In 2008, Great Britain overhauled its disability benefit programme by introducing a new disability determination process called the Work Capability Assessment and a new earnings replacement programme called Employment and Support Allowance. This article examines the British reforms from the perspective of the United States, which may consider changes to its disability benefit programme, the Social Security Disability Insurance programme, in the near future. The article provides an overview of the steps leading to the reform in Great Britain, details how the new programme operates, reviews research on its initial implementation and effects, and identifies lessons for the potential reform of the disability benefit programme in the United States.     

La transition verte: analyser la croissance de l'emploi vert

Les auteurs estiment le nombre des emplois verts en Écosse et analysent son évolution dans le temps en s'appuyant sur les données de l'Enquête sur la main‐d'œuvre du Royaume‐Uni (2011‐2014) et en croisant deux systèmes de classification professionnelle (CITP‐08 et O*NET). Leur cadre méthodologique est transposable à n'importe quelle région. Ils montrent qu'il vaut mieux retenir une définition large des emplois verts, plutôt qu'une définition étroite, pour mesurer correctement l'impact de la transition verte sur l'emploi en général. Ils concluent par ailleurs qu'il faudrait s'intéresser davantage à la qualité des emplois verts et au caractère inclusif de la croissance de l'emploi vert.     

Trois scénarios pour l'avenir du travail

Après avoir rappelé l'histoire longue du concept de travail et les différentes significations attachées au terme au cours des siècles, l'auteure analyse le rapport des Européens à cette valeur, ainsi que les conséquences sur le travail et l'emploi du discours en vogue sur la révolution technologique et ses effets «inéluctables». Elle envisage ensuite l'avenir du travail à la lumière de trois scénarios, celui du «démantèlement du droit du travail», celui de la «révolution technologique» (qui postule la fin de l'emploi par l'automatisation) et celui de la «reconversion écologique», dernier modèle compatible avec l'impératif environnemental, mais aussi avec les attentes placées sur le travail et l'emploi.     

L'effet de la qualification globale sur les rendements de la suréducation et de la sous‐éducation: résultats pour la Malaisie

En Malaisie, l'offre d'emplois qualifiés ne suffit pas à absorber l'afflux de diplômés du supérieur, une situation qui pourrait renforcer la prime salariale des travailleurs surdiplômés et réduire la pénalité salariale des sous‐diplômés. Dans ce contexte, les auteurs s'intéressent à l'effet des compétences au sens large (la «qualification globale») sur ces distorsions, en exploitant des données d'enquête recueillies en 2015 en Malaisie péninsulaire. L'analyse montre que la détention de certaines compétences limite les pénalités induites par les défauts d'appariement sous l'angle du niveau de diplôme. Les établissements de formation et les entreprises auraient donc intérêt à promouvoir l'acquisition de capacités spécifiquement liées à l'emploi.
