We suggest a new comprehensive measure of support given through tax-benefit systems to families with children. Using microsimulation techniques, this accounts for all provisions contingent on the presence of children, while usually only gross child/family benefits are considered. We use EUROMOD, the European Union tax-benefit microsimulation model, to quantify the support for children and analyse its impact on household incomes and child poverty for 19 countries. We find that the conventional approach underestimates on average the total amount of support for children by about one fifth. Furthermore, the differences between the two measures vary considerably across countries and are, therefore, critical for cross-national comparisons.

Since the Soviet Union's collapse, Georgia has undergone profound socio-political and demographic changes. This paper examines recent fertility trends in Georgia using GGS data from 2006. Results show that the postponement of first birth does not significantly account for the decline in childbearing, suggesting that decline is primarily due to a reduction of second-order births. I then investigate determinants of intentions to have a second child in three different periods: now, within three years and ever. Findings reveal that household income, education level and psychological well-being of the respondents as well as their satisfaction concerning the division of tasks within the couple have a significant effect on second birth decision-making. However, these determinants differ significantly regarding the timing of the intended child. On the other hand, there seems to be no effect of ideational changes, represented by a measure of the spread of post-materialist values within the society, on fertility intentions.

Increasing life expectancy coupled with declining birth rates is prompting European countries to revise their current pension schemes. The key elements of pension reforms are 1) introducing funded schemes as a means to supplement the current pay-as-you-go system, and 2) a lengthening of the working careers of European citizens. The policy reforms needed constitutes perhaps the biggest challenge facing European policy makers since the introduction of the welfare state after the Second World War. The urgency of the policy reforms are reflected by the European Council Summits of Stockholm (2001) and Barcelona (2002), where the attending policy makers agreed to both increase the labour force participation among older workers and to delay the retirement period. Notwithstanding the efforts, recent changes in the employment rates and the retirement age indicate that the great majority of countries are way off the targets set for 2010. On the backdrop of the policy challenges lying ahead, we consider in this paper individuals' preferences for work and retirement in 23 European countries. A deeper understanding of these preferences helps policy makers, not only informing them about the potential success of the planned pension reforms, but also to make adjustments to its design that may lead to efficiency gains in welfare provision. We find that on average individuals prefer to retire at a younger age than the current mean retirement age. However, there is huge variation in these preferences both at the individual and country levels. We find rather robust evidence to suggest that individuals are willing to work longer as the average life expectancy is increasing.

Agent-based modelling and numerical simulations are means that facilitate exploring the structural and dynamic characteristics of systems which may prove intractable with analytical methods. This contribution examines the issues related to them with a particular attention to their use in the study of social economic and ecological systems. Besides a general description, the possibilities, limitations and their relationship with other more traditional investigation methods are examined. Special focus is put on the assessment of their validation and reliability. Finally an application example is provided. A simple model is built to analyse the movements of tourists and the relationship between these and the attractiveness of a tourism destination. The results are discussed along with possible future developments.

We use the theory of planned behavior to investigate the role of attitudes, norms and perceived behavioural control on short-term and long-term fertility intentions, using data from Norway (N = 1,307). There is some evidence that, net of other background variables, positive scores on these factors makes it easier to establish concrete childbearing plans, especially among parents. Subjective norms are particularly important among both parents and childless adults, while perceptions of behavioural control have no additional effect once the actual life situation is taken into account. Attitudes are not important in decisions about the timing of becoming a parent, probably because the main issue for childless adults is not the timing, but the decision to have a child or not.

The aim of this paper is to assess the quality of the ranking of institutions obtained with multilevel techniques in presence of different model misspecifications and data structures. Through a Monte Carlo simulation study, we find that it is quite hard to obtain a reliable ranking of the whole effectiveness distribution while, under various experimental conditions, it is possible to identify institutions with extreme performances. Ranking quality increases with increasing intra class correlation coefficient and/or overall sample size. Furthermore, multilevel models where the between and within cluster components of first-level covariates are distinguished perform significantly better than both multilevel models where the two effects are set to be equal and the fixed effect models.

Using a specific data set drawn from the Spanish Module Education to Labour Market Transitions (2000), this paper analyses the labour market entrance of Spanish school leavers and the match between education and work at the early stages of working life. Moreover, special attention is paid to graduates, because Spain experienced a strong growth in the demand for higher education during the last decades of 20th century. The empirical evidence shows that, besides other personal and family individual's characteristics, human capital exerts a strong influence on the finding of an employment. With regard to the match between education and work, the results indicate that over-education is a common phenomenon in the Spanish youth labour market. However, unlike what one could expect, being a graduate seems to be associated to a lower likelihood of over-education in the first employment.

In this paper the question of within-country heterogeneity in patterns of transition to adulthood is addressed, focusing on the exit from the parental home in Spain, a country representative of the latest-late transition to adulthood. Microcensus data are used to investigate the relative weight that structural-contextual factors measured at the municipal level and cultural factors measured at the provincial level might have in explaining regional existing differences in the transition to independent living, by applying multilevel multinomial logistic model on three choices of living arrangements, namely, co-residing with parents, living outside the parental home and in partnership, living outside the parental home and not in partnership.
