Gendered key events in the life course: effects on changes in travel mode choice over time

This paper studies changes in travel mode specific trip rates after life course (and accessibility) related key events from a gender perspective. It is theoretically informed by the mobility biographies approach, and by gender/travel studies. The data used is the German Mobility Panel (GMP) 1994 to 2010 in which households and their members are asked three times in three subsequent years to report the trips they made over a week. The changes reported are regressed to key events over the life course, cohort effects and period effects, while sociodemographics and spatial context attributes are controlled. A cluster–robust regression approach is used to account for the non-independent character of panel observations. Significant effects were found for some key events, including the birth of a child, entry into the labour market, and changes in spatial context, accessibility and mobility. Some effects differed distinctly between men and women, suggesting that men and women are differently affected by life course events. However, taken together the associations found, as well as their gender differences are rather limited. Hence, key events over the life course seem to be only loosely associated with travel mode specific trip rates.     

Regional Insurance and Migration

A dynamic model of migration is developed to study whether labor mobility can hedge people against region-specific shocks, making private or public insurance redundant. The model adopts a novel timing for migration, which is argued to be the time frame suitable for analyzing risk-sharing issues. It also innovates on the existing literature by solving individual migration through convexification of the set of actions. The results show that the role of migration as an insurance mechanism is small: labor mobility cannot fully remove income differentials between regions. It is also shown that a fiscal stabilization scheme is, in general, optimal; moreover, any pure risk-sharing mechanism has no influence on migration flows.     

Intergenerational Mobility under Private vs. Public Education*

Intergenerational earnings mobility is analyzed in a model where human capital is produced using schooling and parental time. In steady states more mobile societies have less inequality, but in the short run higher mobility may result from an increase in inequality. Starting from the same inequality, mobility is higher under public than under private education. A rise in income shocks, for example due to increased returns to ability, or a switch from public to private schooling both increase inequality. However, increased shocks raise mobility in the short run and do not affect it in the long run, whereas an increased role for private schooling reduces mobility in both the short and long run. That these differences may help to identify the source of changes in inequality, and other real‐world implications, are illustrated in a brief discussion of time trends and cross‐country differences.

员工薪酬竞争力与上市公司员工持股

基于员工持股相关理论,本文考察了员工薪酬竞争力对我国上市公司是否实施员工持股的可能影响。实证结果显示,员工薪酬竞争力越弱,企业越可能实施员工持股;且员工薪酬竞争力越弱,员工持股的锁定期限越长、覆盖人数越多以及员工股比例越高。进一步研究发现,员工薪酬竞争力与实施员工持股可能性的负相关关系,只在外部劳动力市场流动性高和内部人力资源成本较高以及融资约束较为严重的样本中显著。上述研究发现表明,上市公司的员工持股在一定程度上是企业在面临外部劳动力市场流动性压力和内部较高人力资源成本以及融资约束时,缓解员工薪酬竞争力不足的现实途径。本文的研究结论为完善上市公司员工持股制度提供了经验证据支持,同时拓展了员工持股、职工薪酬及收入分配等领域的相关研究文献。     

高铁时代“双城记”:新兴产业雇员流动的虹吸效应

中心城市引领城市群发展是当前中国区域协调发展战略的关键路径,如何实现城市群内部的产业分工完善和人才市场化配置是构建新发展格局的重要内容。本文以高铁开通为冲击,研究不同规模城市中新兴产业公司雇员流动的虹吸效应。研究发现:高铁开通之后,新兴产业公司的雇员流动因城市大小出现分化,新兴产业公司在大城市更容易获得雇员,而在小城市则更难,表明新兴产业的雇员流动在高铁开通后存在城市群内更为市场化配置的虹吸效应;进一步研究发现,小城市的雇员流出源自高铁开通后更容易获得大城市的就业机会和缓解其高房价压力,但并不受大城市高工资影响;虹吸效应存在空间限制,主要存在于距离大城市2小时高铁圈的小城市内。本文表明以高铁连通为典型的城市群一体化进程对不同规模城市的新兴产业成长具有差异化影响,这不仅对产业分工和劳动力流动的相关研究作出补充,也对因地制宜推进区域间协调发展提供了参考。     

Advancing the evidence base for public policies impacting on dietary behaviour,physical activity and sedentary behaviour in Europe: The Policy Evaluation Network promoting a multidisciplinary approach

Non-communicable diseases (NCDs) are the leading cause of global mortality. As the social and economic costs of NCDs have escalated, action is needed to tackle important causes of many NCD’s: low physical activity levels and unhealthy dietary behaviours. As these behaviours are driven by upstream factors, successful policy interventions are required that encourage healthy dietary behaviours, improve physical activity levels and reduce sedentary behaviours of entire populations. However, to date, no systematic research on the implementation and evaluation of policy interventions related to these health behaviours has been conducted across Europe. Consequently, no information on the merit, gaps, worth or utility of cross-European policy interventions is available, and no guidance or recommendations on how to enhance this knowledge across European countries exists. As part of the Joint Programming Initiative “A Healthy Diet for a Healthy Life” (JPI HDHL), 28 research institutes from seven European countries and New Zealand have combined their expertise to form the Policy Evaluation Network (PEN). PEN’s aim is to advance tools to identify, evaluate, implement and benchmark policies designed to directly or indirectly target dietary behaviours, physical activity, and sedentary behaviour in Europe, as well as to understand how these policies increase or decrease health inequalities. Using well-defined evaluation principles and methods, PEN will examine the content, implementation and impact of policies addressing dietary behaviour, physical activity levels and sedentary behaviour across Europe. It will realise the first steps in a bespoke health policy monitoring and surveillance system for Europe, and refine our knowledge of appropriate research designs and methods for the quantification of policy impact. It will contribute to our understanding of how to achieve successful transnational policy implementation and monitoring of these policies in different cultural, demographic or socioeconomic settings. PEN will consider equity and diversity aspects to ensure that policy actions are inclusive and culturally sensitive. Finally, based on three policy cases, PEN will illustrate how best to evaluate the implementation and impact of such policies in order to yield healthy diets and activity patterns that result in healthier lives for all European citizens.     

Productivity insurance: The role of unemployment benefits in a multi-sector model

We construct a multi-sector search and matching model where the unemployed receives idiosyncratic productivity shocks that make working in certain sectors more productive than in the others. Agents must decide which sector to search in and face moving costs when leaving their current sector for another. In this environment, unemployment is associated with an additional risk: low future wages if mobility costs preclude search in the appropriate sector. This introduces a new role for unemployment benefits – productivity insurance while unemployed. For plausible parameterizations unemployment benefits increase per-worker productivity. In addition, the welfare-maximizing benefit level decreases as moving costs increase.

Housing capital-gains taxation and homeowner mobility: Evidence from the Taxpayer Relief Act of 1997

We provide new evidence on the impact of housing capital-gains taxation on homeowner behavior by examining residential mobility before and after the Taxpayer Relief Act of 1997 (TRA97), which generated the most sweeping reform of capital-gains taxation in the last two decades. In addition to lowering marginal tax rates on long-term capital gains for all assets, TRA97 also eliminated any differential treatment of housing gains above and below age 55, allowing all homeowners to qualify for capital-gains exclusions. Utilizing data drawn from the Current Population Survey (CPS) on either side of the law change (1996 and 1998) on homeowners just above (56–58 year olds) and below (52–54 year olds) the age-55 threshold and a reduced-form, difference-in-difference empirical approach, our estimates suggest that the repeal of the differential capital-gains tax treatment by age embodied in TRA97 had an economically important and statistically significant impact on the residential mobility of under-55 homeowners. Across a variety of specifications, the repeal raised the mobility rate by around 1–1.4 percentage points, which, for a mean mobility rate of 4 percentage points, represented an increase in the mobility rate of homeowners in their early 50s by 22–31%. Furthermore, the bulk of this effect was concentrated among highly mobile homeowners who a priori were more likely to have wanted to trade down (e.g., divorced, empty nesters), those facing higher capital gains tax rates, and those living in states that had experienced higher rates of nominal appreciation.
