How does pay-for-performance (P4P) impact productivity, multitasking, and the composition of workers in mission-oriented jobs? These are central issues in sectors like education or healthcare. We conduct a laboratory experiment, manipulating compensation and mission, to answer these questions. We find that P4P has positive effects on productivity on the incentivized dimension of effort and negative effects on the non-incentivized dimension for workers in non-mission-oriented treatments. In mission-oriented treatments, P4P generates minimal change on either dimension. Participants in the non-mission sector – but not in the mission-oriented treatments – sort on ability, with lower ability workers opting out of the P4P scheme.

Public procurement outcomes depend on the ability of the procuring agency to select well-performing suppliers. Should public administrations be granted more or less discretion in their decision making? Using Italian data on municipal public works tendered in the period 2009-2013, we study how a reform extending the scope of bureaucrat discretion affects supplier selection. We find that the share of contracts awarded to politically connected firms increases while the (ex-ante) labor productivity of the winning firm decreases, thus suggesting a potential misallocation of the public funds. These effects are concentrated among lower quality procuring agencies.

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.

Abortion in Italy is free of charge and legal in a broad set of circumstances, but 71% of gynecologists refuse to perform abortions for reasons of conscientious objection. We assess whether the diverse prevalence of conscientious objection across Italian regions is linked to the inter-regional mobility of women seeking an abortion and to differences in terms of waiting time preceding the operation. Focusing on the period between 2002 and 2016, we perform a panel data analysis at the regional level, showing that a higher prevalence of objecting professionals is associated to a higher share of women having an abortion outside the region and to longer waiting times. Furthermore, using microdata on over one million abortions recorded in Italy in the same period, we find that conscientious objection is a significant driver of the individual decision of having an abortion out of the region of residence. All the models account for economic and demographic characteristics of regions, and for other possible determinants of interregional mobility. Overall, results suggest that conscientious objection can limit access to abortion at the local level.

According to the existing theoretical literature, there are several channels through which privatization of State-owned enterprises and assets may shape the distribution of income, either increasing or decreasing the level of inequality. Assessing the actual distributional impact of privatization becomes therefore an empirical matter. This paper is a first attempt to empirically investigate the relationship between privatization and income inequality through redistribution, focusing on the role of democratic institutions in developing countries. Using an unbalanced panel of low and middle-countries in the period 1988-2008, we find that an increase in privatization revenue is negatively and significantly correlated with net-income inequality when democratic institutions are well consolidated. All the robustness checks we perform confirm this finding. Thus, our analysis seems to suggest that, in developing countries, policy makers’s choice of implementing divestiture programs while democratizing at the same time may lead to an improvement in income equality.

This article explores opinions and semantic orientation around fertility and parenthood by scrutinizing filtered Italian Twitter data. We propose a novel methodological framework relying on Natural Language Processing techniques for text analysis, which is aimed at extracting sentiments from texts. A manual annotation for exploring sentiment and attitudes to fertility and parenthood was applied to Twitter data. The resulting set of tweets (corpus) was analysed through sentiment and emotion lexicons in order to highlight how affective language is used in this domain. It emerges that parents express a generally positive attitude towards their children and being and become parents, but quite negative sentiments on children’s future, politics and fertility and also parental behaviour. Exploiting geographical information from tweets, we find a significant correlation between the prevalence of positive sentiments about parenthood and macro-regional indicators for both life satisfaction and fertility levels.

We examine the causal effect of legislative activity on private benefits, which have been largely neglected by previous research in legislative studies. By relying on a natural experiment in New Zealand, where randomly selected MPs are given the opportunity to propose legislation, we find evidence for a causal relation between proposing a (successful) bill and the private benefits MPs receive, in terms of gifts and payments for services. We conclude that the allocation of private benefits depends on legislative performance.

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.

This article combines two apparently distinct strands of contemporary research on fertility: the literature on economic uncertainty and fertility and the literature on subjective well-being and fertility. We advance the hypothesis that the impact of term-limited work contracts and precarious jobs on fertility intentions is channeled by an individual’s level of subjective well-being. To test this hypothesis, we adopt a formal framework for causal inference and apply techniques of mediation analysis to data from two rounds of the European Social Survey (ESS 2004 and 2010). Our analysis clearly suggested that the impact of employment uncertainty on fertility intentions depended on the level of subjective well-being: the negative effect was found only when subjective well-being was relatively low (i.e. life satisfaction levels equal or below 6). Detailed results show that parents and younger individuals reduced their fertility intentions more than the childless and older individuals when experiencing economic uncertainty and facing low subjective well-being. We also found that in 2010 – while the economic crisis was underway – it was especially the deterioration in men’s position in the labor market that inhibited fertility planning.

We consider the case when it is of interest to study the different states experienced over time by a set of subjects, focusing on the resulting trajectories as a whole rather than on the occurrence ofspecific events. Such situation occurs commonly in a variety of settings, for example in social and biomedical studies. Model‐based approaches, such as multistate models or Hidden Markov models, are being used increasingly to analyze trajectories and to study their relationships with a set of explanatory variables. The different assumptions underlying different models typically make the comparison of their performances difficult. In this work we introduce a novel way to accomplish this task, based on microsimulation‐based predictions. We discuss some criteria to evaluate one model and/or to compare competing models with respect to their ability to generate trajectories similar to the observed ones.
