When exposed to similar migration flows, countries with different institutional systems may respond with different levels of openness. We study in particular the different responses determined by different electoral systems. We find that Winner Take All countries would tend to be more open than countries with PR when all other policies are kept constant, but, crucially, if we consider the endogenous differences in redistribution levels across systems, then the openness ranking may switch.

Scarcity of female academics has been well documented for math-intensive or STEM fields. We investigate whether a lack of female instructors creates a demand for diversity on the student side. In an incentivized instructor-choice experiment on MTurk, we experimentally vary the gender balancedness of the instructor pool and let participants choose one additional instructor among one male and one female. We find that only women are more likely to choose the female instructor when the pool of instructors is male-dominated, suggesting that female students appreciate a more balanced instructor pool if female professors are scarce. We further document that women also appreciate diversity (though to a lesser extent) if the scarce gender is of the opposite sex. In contrast, men only appreciate diversity if the scarce gender is their own.

This paper investigates how social interactions among friends shape fertility. We specifically examine whether and how friends' fertility behaviour affects an individual's transition to parenthood. By integrating insights from economic and sociological theories, we elaborate on the mechanisms via which interactions among friends might affect an individual's risk of becoming a parent. By exploiting the survey design of the Add Health data, we follow a strategy that allows us to properly identify interaction effects and distinguish them from selection and contextual effects. We engage in a series of discrete time event history models with random effect at the dyadic level. Results show that, net of confounding effects, a friend's childbearing increases an individual's risk of becoming a parent. We find a short-term, curvilinear effect: an individual's risk of childbearing starts increasing after a friend's childbearing, it reaches its peak around two years later, and then decreases.

We empirically investigate the existence of the Environmental Kuznets Curve (EKC) focusing on a sample of 39 countries in the period 1996-2014. Using an interaction model, we also analyze whether the effectiveness of environmental taxes in reducing CO 2 emissions depends on the quality of political institutions. Our results show that the inverted U-shaped relationship between environmental stress and economic development holds independently of the quality of political institutions and environment related taxes. Moreover, an increase in the environmental tax revenue has the expected reducing effect on environmental degradation only in countries with more consolidated democratic institutions, higher civil society participation and less corrupt governments. Our findings also show that the effects on environmental stress of revenue neutral shifts to different tax sources depend not only on the quality of political institutions, but also on the kind of externality the policymaker aims at correcting.

As unemployment rises across the European Union (EU) it is important to understand the extent to which the incomes of the new unemployed are protected by tax-benefit systems and to assess the cost pressures on the governments. This paper uses the EU tax-benefit model EUROMOD to explore these issues, comparing effects in five countries. It provides evidence on the differing degrees of resilience of the household incomes of the newly unemployed due to the variations in the protection offered by the tax-benefit systems, according to whether unemployment benefit is payable, the household situation of the unemployed person, and across countries.

ABSTRACT This paper studies a collection of data on economic inequality in fifteen towns in the Southern and Northern Low Countries from the late Middle Ages until the end of the nineteenth century. By using a single and consistent source type and adopting a uniform methodology, it is possible to study levels of urban economic inequality across time and place comparatively. The results indicate a clear growth in economic inequality in the two centuries prior to the industrial revolution and the onset of sustained economic growth per capita. The general occurrence of this rise throughout regions with dissimilar economic trajectories contradicts the existence of a straightforward trade-off between growth and inequality as conjectured by Simon Kuznets (1955). Instead, the results presented lend support to the ‘classical’ economists’ explanation of inequality as the consequence of a changing functional distribution of income favouring capital over labour in the long run.

ABSTRACT This paper provides an overview of economic inequality in the Florentine State (Tuscany) from the late fourteenth to the late eighteenth century. Regional studies of this kind are rare, and this is only the second-ever attempt at covering such a long period. Consistent with recent research conducted on other European areas, during the Early Modern period we find clear indications of a tendency for economic inequality to grow continually, a finding that for Tuscany cannot be explained as the consequence of economic growth. Furthermore, the exceptionally old sources we use allow us to demonstrate that a phase of declining inequality, lasting about one century, was triggered by the Black Death from 1348 to 1349. This finding challenges earlier scholarship and significantly alters our understanding of the economic consequences of the Black Death. We also take into account other important topics, such as the change over time of the patrimony of the Church and of poverty. Particular attention is paid to the latter, and estimates of the prevalence of the poor in time and space are provided and discussed, also taking into account the definition and perception of the poor.

ABSTRACT This article provides a comprehensive picture of economic inequality in northwestern Italy (Piedmont), focusing on the long-term developments occurring from 1300 to 1800 ca. Regional studies of this kind are rare, and none of them has as long a timescale. The new data proposed illuminate many little-known aspects of wealth distribution and general economic inequality in preindustrial times, and support the idea that during the Early Modern period, inequality grew everywhere: both in cities and in rural areas, and independently from whether the economy was growing or stagnating. This finding challenges earlier views that explained inequality growth as the consequence of economic development. The importance of demographic processes affecting inequality is underlined, and the impact of severe mortality crises, like the Black Death, is analyzed.

This paper provides an overview of economic inequality in Germany from the fourteenth to the nineteenth centuries. It represents the first attempt at reconstructing long-term trends in wealth inequality in a central European area. It builds upon the data produced by the German Historical School, which from the late nineteenth century pioneered inequality studies, but also adds new archival information for selected communities and areas. Overall during the early modern period inequality was found to be increasing, as seems to have been the case in most of the European continent, but with an important local specificity: the terribly destructive Thirty Years’ War (1618-48), together with the plague epidemic of 1627-29, are found to have caused a temporary but significant phase of reduction in inequality. This is in stark contrast to other European areas for which information is available, from Italy to the Low Countries, where during 1500-1800 inequality growth was monotonic. Some evidence of a drop in inequality is also found after the Black Death of 1348-49, but in at least part of Germany inequality growth seems to have resumed immediately after that plague. Our findings contribute to deepen and to nuance our knowledge of long-term inequality trends in preindustrial Europe, and offer new material to current debates on the determinants of inequality change in western societies, past and present.
