Using data from the British Household Panel Survey, this paper assesses the influence of personality traits on timing of motherhood and investigates whether, and in what way, personality traits can explain the differences in maternity timing between more and less educated women. We estimate a log-logistic model of the time to first child birth and show that there is a statistically significant relationship between the Big Five personality traits and timing to motherhood. The results also show that within the more educated group, women who have an average to high score on Openness have lower hazards of childbirth.

Using the British Household Panel Survey this paper explores the extent to which marital and cohabiting unions differ with respect to the short term effects of union dissolution on psychological distress. We test the hypothesis that spouses experience larger negative effects but the results show that this difference is not statistically significant once the presence of children is controlled for. Having children is found to be a major source of psychological distress when one is going through union dissolution. However, it does not explain high psychological distress which seems to be associated with intrinsic factors (the personality trait neuroticism) rather than with contextual factors.

Are public good games really capturing individuals’ willingness to contribute to real-life public goods? To answer this question, we conducted a lab-in-the-field experiment with communities who own collective goods. In our experiment, subjects voluntarily contribute to a common pool, which can either be subdivided in individual vouchers, as in standard public good games, or used to acquire collective goods, as it happens for real-life public goods. We show that participants’ contributions are larger when the voucher is paid individually, suggesting that individuals’ willingness to contribute to public goods may be overestimated when based on results from laboratory experiments.

The north-south gap in Italian social capital has been considered by international scholars as an example of how cultural diversity within a country can generate dierent developmental outcomes. Most studies, however, suer from limited external validity and measurement-error problems. This paper exploits a new and representative online lab-experiment to assess social capital patterns in Italy. Our study only partially conrms previous ndings: northerners perform better in trustworthiness, but they are statistically similar to southerners in many other economic preferences such as cooperation, trust, expected trustworthiness, altruism, and risk tolerance. A novelty of this study is that the gap in trustworthiness stems from the lower reciprocity of southerners in response to large transfers from trustors, and it is characterized by the intergenerational transmission of norms. Eective convergence policies should target, within social capital, reciprocity, while looking to other, and perhaps more compelling gaps.

In the past decade, the world has witnessed increased climate change impacts with many countries experiencing more frequent and more severe climate extremes. With public support being fundamental in scaling up climate action, here, we analyze the impact of exposure to climate extremes on environmental concern and Green voting for a large panel of European countries. Combining high-resolution climatological data with regionally aggregated and harmonized information on environmental concern (42 Eurobarometer surveys, 2002-2019, 34 countries) and European Parliamentary electoral outcomes (7 elections, 1990-2019, 28 countries) at the subnational level, we find a significant and sizeable effect of temperature anomalies, heat episodes and dry spells in the previous 12 months on green concern and voting. The effects differ significantly by region and are most pronounced in regions with a cooler Continental or temperate Atlantic climate, and weaker in regions with a warmer Mediterranean climate. The relationship is moderated by regional GDP suggesting that climate change experience increase public support for climate action only under favorable economic conditions. By empirically documenting the important role of contextual influences and regional differences on green concern and voting, our findings have important implications for the current efforts to promote and implement climate actions in line with the Paris Agreement.

Studies adopting the Theory of Planned Behavior (TPB) mostly use quantitative methods. Sometimes, however, researchers choose to use a qualitative method because of the nature of available data (e.g., interviews) or availability of only a limited number of cases. This paper describes a study in which the TPB was used with qualitative methods to explain differences in university teaching. It focuses primarily on the methods used: qualitative data coding, data analysis and interpretation, and methods for presenting and supporting results. The study explored factors which influence university teachers to adopt teaching models based on online social interaction when an e-learning platform is used to complement undergraduate classroom teaching. Participants were 26 university teachers (15 from Australia and 11 from Italy). They responded to a semi-structured interview based on the TPB. Three approaches to use of e-learning platforms were identified: upload of materials, use of discussion forums, and computer-supported collaborative learning (CSCL). Using this approach, it was possible to highlight substantial differences in the attitudes, social influence, and perceived behavioral control among the three groups.

Good estimates of HIV prevalence are important for policy makers in order to plan
control programs and interventions. Although population-based surveys are now considered the "gold standard" to monitor the HIV epidemic, they are usually plagued by problems of nonignorable nonresponse. This paper uses the partial identification approach to assess the uncertainty caused by missing HIV status. We show how to exploit the availability of panel data and the absorbing nature of HIV infection to narrow the worst-case bounds without imposing assumptions on the missing-data mechanism. Applied to longitudinal data from rural Malawi, the Malawi Diffusion and Ideational Change Project (MDICP), our approach results in a reduction of the width of the worst-case bounds by about 18.2 percentage points in 2004, 13.2 percentage points in 2006, and 2.4 percentage points in 2008. We also use plausible instrumental variable and monotone instrumental variable restrictions to further narrow the bounds.

The vast majority of studies looking into the relationship between childbearing and subjective well-being uses overall measures where respondents either report their general level of happiness or their life satisfaction, leaving substantial doubt about the underlying mechanisms. However, life satisfaction and happiness are intuitively multidimensional concepts, simply because there cannot be only one aspect that affects individuals' well-being. In this study, by considering seventeen specific life satisfaction domains, these features come out very clearly. Whereas all the domains considered matter for the overall life satisfaction, only three of them, namely satisfaction with leisure, health and satisfaction with the partnership, change dramatically surrounding childbearing events. Even though we cannot generalize (since these results stems from one particular panel survey, i.e. Household Income and Labour Dynamics in Australia data), it appears that the typical anticipation and post-child decrease of life satisfaction, so often found in existing studies, stem from changes in these three domains.

As more studies focus on social trust and link it to the working of economies and societies, measuring properly this concept is growing in importance. Indeed, as it is a complex construct, entangled to other notions such as reciprocity, it is hard to obtain reliable and accurate measures of it. To mend for this, the OECD has launched Trustlab: a project aimed at creating the first internationally comparable and nationally representative database on trust and social preferences using both survey and experimental approaches. As of March 2018, Trustlab surveys have been run in 6 countries. In this paper we present the data and peculiarities of Trustlab Italy, in which, in addition to the measures of trust, data on personality traits and fertility intentions have been collected.
