The welfare cost of unpriced heterogeneity in insurance markets

2016

We consider the welfare loss of unpriced heterogeneity in insurance markets, which results when private information or regulatory constraints prevent insurance companies to set premiums reflecting expected costs. We propose a methodology which uses survey data to measure this welfare loss. After identifying some “types” which determine expected risk and insurance demand, we derive the key factors defining the demand and cost functions in each market induced by these unobservable types. These are used to quantify the efficiency costs of unpriced heterogeneity. We apply our methods to the US Long-Term Care and Medigap insurance markets, where we find that unpriced heterogeneity causes substan…

Nonlinearity in intergenerational income transmission: A cross-country analysis

2016

Abstract The aim of this paper is to explore nonlinearity in intergenerational income transmission. We use a set of occupational tables in different countries to test nonlinearity. We also empirically address how policy variables can affect nonlinearity. Our findings suggest that concavity is supported in those societies with less credit constraints, but with more poverty and income inequality; education has an increasing effect on convexity.

Voters’ preferences and electoral systems: the EuroVotePlus experiment in Italy

2016

Motivated by the need to understand voting behaviour under different electoral rules, Laslier et al. (Eur Union Polit, 16(4):601–615, 2015) have conducted an online experiment, the EuroVotePlus experiment, focusing on the effects of the different rules adopted to elect members of the European parliament on voters’ behaviour. The experiment took place in several European countries in the 3 weeks before the 2014 elections for the European Parliament. This paper focuses on the Italian data. Firstly, we show that the behaviour of Italian respondents is consistent with the empirical findings at the European level. Then, we exploit the change from open list to closed list elections implemented in…

Do we value mobility?

2015

Is there a trade-off between people's preference for income equality and income mobility? Testing for the existence of such a trade-off is difficult because mobility is a multifaceted concept. We analyse results from a questionnaire experiment based on simple precise concepts of income inequality and income mobility. We fnd no direct trade-off in preference between mobility and equality, but an indirect trade-off, applying when more income mobility can only be obtained at the expense of some income inequality. Mobility preference - but not equality preference - appears to be driven by personal experience of mobility.

Socioeconomic effects and the role of public spending decomposition on income mobility: a moderated regression model

2022

The aim of this paper is to investigate, empirically, what components of public spending imply a decreasing effect on income mobility, and what components create income opportunities, also discussing the role of government effectiveness. The role of the components of government expenditure is analysed in the association between intergenerational income mobility and socioeconomic characteristics, which are relevant for the life chances of children. Using the Global Database on Intergenerational Mobility, containing estimates of intergenerational income mobility at country level, and applying the moderated regression model, the results show strikingly consistent patterns. A country with more …

Can stability of foreign aid agreement reduce global income inequality?

2017

Abstract Global initiatives on debt relief call for increasing foreign aid assistance to alleviate income inequality. But the potential gains from foreign aid policy coordination may be limited by the willing participation of diverse and self-interested donor countries. If stability of the foreign aid agreement does not occur, then aid effectiveness fails. Thus, the aim of this paper is to investigate the effects of the stability of foreign aid agreement on income redistribution amongst countries. The findings show that stability has positive effects on income mobility from the rich to the poorest countries reducing global income inequality.

An extended shakedown theory for elastic-plastic-damage material models

1996

Internal variable elastic-plastic-damage, or elastic-damage, material models endowed with free energy are considered. Referring to a structure of such a material subjected to loads varying inside a given domain, the classical notion of (elastic) shakedown is widened to signify that the structure eventually responds to the loads in an elastic manner after certain (finite) amounts of plastic strain and/or damage have been produced. For structures fulfilling an ad-hoc D-stability requisite, an extended shakedown theorem is presented as a generalization of the classical Melan theorem to nonlinear elasticity and damage - besides nonlinear hardening. For common materials exhibiting linear elastic…

MULTICRITERIA OPTIMAL DESIGN OF CONTINUOUS CIRCULAR PLATES

2010

The paper is devoted to a quite general version of the multicriteria optimal (minimum volume) design of axisymmetric circular plates. The constitutive material is considered as elastic perfectly plastic without any ductility limit and the actions are assumed as quasi-statically variable within a given load domain. In the design problem formulation different resistance criteria are considered, in order to investigate all the possible structural limit responses, and for each one a suitably chosen safety factor is chosen. The optimal design problem is formulated as the search for the minimum structure volume according with a statical approach. The features of the optimal structures will be stu…
