Chapter
Full-text available
This chapter analyses in which ways diffusion based on interdependent policy learning explains expenditure on active labour market policies (ALMP) in the OECD countries. By applying error correction models using multiplicative spatial Prais-Winsten regressions for analyzing the diffusion of ALMPs in 22 OECD countries from 1991–2013, we find evidenc...
Article
Full-text available
Parental leaves are, besides unemployment, the main reason for career breaks in early career. Despite the progress in recent decades towards more equal sharing of childcare between mothers and fathers, the labour market risk due to parenting remains mainly with women. In this article, we analyse how parental leaves relate to early career trajectori...
Chapter
The quantitative-empirical research on the political economy of welfare state reforms has offered multiple explanations on how governments impact social policy reforms. The emergence of the ‘dependent variable problem’ and the ‘independent variable problem’, however, clearly calls into question some of the previous findings. In this chapter, we off...
Article
Full-text available
This study investigates how policies shape retirement and labour market participation of older workers and thus help extending working lives. It employs a time‐series–cross‐section analysis of the effects of macro‐level institutional pull, push and retention factors on effective retirement age and employment rate of older workers in 15 OECD countri...
Article
Full-text available
Yhteiskuntapolitiikka 2:2019 Tässä analyysissä tarkastelemme nuorten aikuisten työurakiinnittymistä. Kysymme, ovatko perhe-vapaat riski työmarkkinakiinnittymiselle työuran alkuvaiheessa? Työuran alkuvaiheella on ratkaiseva merkitys työllistymiseen ja myöhempään urakehitykseen. Sillä on myös suuri merkitys työeläketurvan kannalta, koska työeläke kar...
Chapter
In diesem Beitrag wird das Konzept der Generosität erläutert, das den allgemeinen Umfang verschiedener Sozialschutzprogramme umfasst. Es wird argumentiert, dass die Generosität von Wohlfahrtsstaaten nur unzureichend durch die Sozialausgaben erfasst werden kann. Seit den 1990er Jahren wurden daher Indikatoren entwickelt, die die Generosität des Wohl...

interactplot is a tool for generating plots of predicted values or marginal effects for polynomials or interaction terms after a multiplicative regression. The program detects multiplicative terms within the last estimated regression model, automatically calculates statistics calculated from predictions and automatically generates a combined graph....

Code
(install via ssc install ihstrans) ihstrans is a tool for inverse hyperbolic sine (IHS)-transformation of multiple variables. The command can process multiple variables at once, and therefore can handle datasets that are in wide format and allows for setting casewise missings for observations. The program automatically detects string variables and...
Code
PANELL displays individual and overall panel length of a given set of variables of a longitudinal/panel dataset. The output shows how many observations are non-missing for one variable or a certain combination of multiple variables.

Project
Webpage: www.cwed2.org The Comparative Welfare Entitlements Dataset (CWED) provides systematic data on institutional features of social insurance programs in 33 countries spanning much of the post-war period. CWED 2 is a significant extension and update of the information collected and published online as CWED by Lyle Scruggs in 2004. The purpose of the dataset is to provide an essential complement to program spending data that is available from international sources like the OECD's Social Expenditure Database. Data is provided for unemployment and sickness insurance as well as for standard and minimum pensions and covers income replacement rates of cash benefits, eligibility criteria and coverage of the programs. At the time being, replacement rates are available for two household types (single person with 100 % earnings of an Average Production Worker (APW) and married couple with two children with 100/0 % earnings of APW). Replacement data for further household types and earning categories will be added soon.
Project
Early career development in terms of labour market attachment and earnings is important for later life, but also for future pensions and thus incomes in old age. In this project, we study the effects of parenthood, parental leave breaks and other career discontinuities on labour market attachment and earnings development of young Finnish women and men. We use register data of the Finnish Centre for Pensions and Statistics Finland’s data for cohorts born between 1967 and 1987. We carry out trajectory analyses in order to identify different early career paths and crucial covariates that are explaining those employment trajectories.
