Opinion copulas, homophily and multimodal marginals

Askitas, Nikos - 2017

An empirically founded and widely established driving force in opinion dynamics is homophily i.e. the tendency of "birds of a feather" to "flock together". The closer our opinions are the more likely it is that we will interact and converge. Models using these assumptions are called bounded...

Modelling the joint distribution of income and wealth

Jäntti, Markus; Sierminska, Eva; Van Kerm, Philippe - 2015

This paper considers a parametric model for the joint distribution of income and wealth. The model is used to analyze income and wealth inequality in five OECD countries using comparable household-level survey data. We focus on the dependence parameter between the two variables and study whether...

A flexible sample selection model : a GTL-copula approach

Hasebe, Takuya; Vijverberg, Wim P. M. - 2012

In this paper, we propose a new approach to estimating sample selection models that combines Generalized Tukey Lambda (GTL) distributions with copulas. The GTL distribution is a versatile univariate distribution that permits a wide range of skewness and thick- or thin-tailed behavior in the data...

Is inequality of opportunity robust to the measurement approach?

Ramos Morilla, Xavier; Van de Gaer, Dirk - 2017

Recent literature has suggested many ways of measuring equality of opportunity. We analyze in a systematic manner the various approaches put forth in the literature to show whether and to what extent different choices matter empirically. We use EU-SILC data for most European countries for 2005...

Equality of opportunity for well-being

Mahler, Daniel Gerszon; Ramos Morilla, Xavier - 2017

A growing literature has tried to measure the extent to which individuals have equal opportunities to acquire income. At the same time, policy makers have doubled down on efforts to go beyond income when measuring well- being. We attempt to bridge these two areas by measuring the extent to which...

Dynamic efficiency and pareto optimality in a stochastic OLG model with production and social security

Barbie, Martin; Hagedorn, Marcus; Kaul, Ashok - 2000

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...

Stochastic complementarity

Manzini, Paola; Mariotti, Marco; Ülkü, Levent - 2018

The Hicksian definition of complementarity and substitutability may not apply in contexts in which agents are not utility maximisers or where price or income variations, whether implicit or explicit, are not available. We look for tools to identify complementarity and substitutability satisfying...

The virtue of being underestimated : a note on discriminatory contracts in hidden information models

Schnedler, Wendelin - 2001

A standard hidden information model is considered to study the influence of the a priori productivity distribution on the optimal contract. A priori more productive (hazard rate dominant) agents work less, enjoy lower rents, but generate a higher expected surplus.

Searching for rehabilitation in nonparametric regression models with exogenous treatment assignment

Henderson, Daniel J.; Maasoumi, Esfandiar - 2012

This paper offers some new directions in the analysis of nonparamertric models with exogenous treatment assignment. The nonparametric approach opens the door to the examination of potentially different distributed outcomes. When combined with cross-validation, it also identifies potentially...
