Values, inequality and happiness

This paper examines the relationship between inequality and happiness through the lens of heterogeneous values, beliefs and inclinations. Drawing upon opinion data from the European Social Survey for twenty-three countries, we find that individual views on a wide range of themes can be effectively summarized by two orthogonal dimensions: moderation and inclusiveness. The former is defined as a tendency to take mild stands on issues rather than extreme ones; the latter is defined as the degree of support for a social model that grants equal rights to everyone who willingly subscribes to a shared set of rules, regardless of background and circumstances. These traits matter when it comes to how inequality affects subjective well-being; specifically, those who are either more moderate or more inclusive than their average compatriots prefer lower levels of inequality. In the case of moderation, inequality aversion can be read in terms of a desire for stability: people who are reluctant to take strong stands are especially wary of conflict, tension and unrest, which often go handin-hand with disparities. In the case of inclusiveness, the main element at play is likely to be distress accruing on a perception of unfairness.happiness, inequality, heterogeneity

Intergenerational Transfers in Italy

In this paper we examine the role of intergenerational transfers in the wealth accumulation of Italian households. Received transfers represent an important share of the net wealth held by households. Direct estimates referring to 2002 range from 30 to 55 per cent, depending on the inclusion of the income stream produced by transferred assets. This share has shown a tendency to increase over the last decade. In a lifetime perspective, the ratio of transfers received over the whole life span to the total amount of resources, both computed at the age of 15, is on average equal to 4.6 per cent, a significant share considering the size of the denominator. Transfers are very concentrated, more than income and wealth, even when considered in a lifetime perspective. Households receiving transfers show higher levels of lifetime income, consumption, net wealth and given transfers than non-recipient households. Richer households receive larger transfers but, as a proportion of their current wealth holdings, transfers are greater for poorer households than richer ones. These results cannot be interpreted as an equalising effect of transfers, because people tend to react to transfers, changing their saving and consumption behaviour. The correlation between transfers (received or expected over the whole life span) and lifetime income is positive. Again, richer households receive greater inheritances and other wealth transfers than poorer households; as a proportion of their lifetime income, transfers are greater for poorer households than richer ones. This result is likely to be due to the much more important role played by family background variables than bequests as factors of transmission of inequality of lifetime resources. Finally, we find a positive relationship between left-to-children bequests and received-from-parents inheritances; this relationship holds even after controlling for lifetime resources, suggesting the importance of the role of family traditions.Households, Wealth, Intergenerational transfers

Inequality and Happiness

This paper examines the relationship between inequality and happiness through the lens of heterogeneous values, beliefs and inclinations. Drawing upon opinion data from the European Social Survey for twenty-three countries, we find that individual views on a wide range of themes can be effectively summarized by two orthogonal dimensions: moderation and inclusiveness. The former is defined as a tendency to take mild stands on issues rather than extreme ones; the latter is defined as the degree of support for a social model that grants equal rights and opportunities to everyone who willingly subscribes to a shared set of rules, regardless of background and circumstances. These traits matter when it comes to how inequality affects subjective well-being; specifically, those who are either more moderate or more inclusive than their average compatriot tend to dislike inequality. With reference to moderation, inequality aversion can be read in terms of a desire for stability: people who are reluctant to take strong stands probably dislike conflict, tension and unrest, which normally accompany inequalities. With reference to inclusiveness, the main element at play is likely to be distress accruing to a perception of unfairness.Happiness, inequality, heterogeneity

Universal High-Frequency Behavior of Periodically Driven Systems: from Dynamical Stabilization to Floquet Engineering

We give a general overview of the high-frequency regime in periodically driven systems and identify three distinct classes of driving protocols in which the infinite-frequency Floquet Hamiltonian is not equal to the time-averaged Hamiltonian. These classes cover systems, such as the Kapitza pendulum, the Harper-Hofstadter model of neutral atoms in a magnetic field, the Haldane Floquet Chern insulator and others. In all setups considered, we discuss both the infinite-frequency limit and the leading finite-frequency corrections to the Floquet Hamiltonian. We provide a short overview of Floquet theory focusing on the gauge structure associated with the choice of stroboscopic frame and the differences between stroboscopic and non-stroboscopic dynamics. In the latter case one has to work with dressed operators representing observables and a dressed density matrix. We also comment on the application of Floquet Theory to systems described by static Hamiltonians with well-separated energy scales and, in particular, discuss parallels between the inverse-frequency expansion and the Schrieffer-Wolff transformation extending the latter to driven systems.Comment: 84 pages, 25 figures, 4 appendice
