Happiness functions with preference interdependence and heterogeneity: The case of altruism within the family

Bruhin, Adrian; Winkelmann, Rainer - 2007

This study investigates the prevalence and extent of altruism by examining the relationship between parents' and their adult children's subjective well-being in a data set extracted from the German Socio-Economic Panel. In order to segregate the share of parents with altruistic preferences from...

Risk and rationality: Uncovering heterogeneity in probability distortion

Bruhin, Adrian; Fehr-Duda, Helga; Epper, Thomas F. - 2007

It has long been recognized that there is considerable heterogeneity in individual risk taking behavior but little is known about the distribution of risk taking types. We present a parsimonious characterization of risk taking behavior by estimating a finite mixture regression model for three...

Robust fitting of mixture regression models

Bai, Xiuqin; Yao, Weixin; Boyer, John E. - In: Computational Statistics & Data Analysis 56 (2012) 7, pp. 2347-2359

The existing methods for fitting mixture regression models assume a normal distribution for error and then estimate the … an EM-type algorithm to estimate the mixture regression models. Using a Monte Carlo simulation study, we demonstrate that …

Taking "Don't Knows" as Valid Responses: A Complete Random Imputation of Missing Data

Kroh, Martin - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2004

Incomplete data is a common problem of survey research. Recent work on multiple imputation techniques has increased analysts' awareness of the biasing effects of missing data and has also provided a convenient solution. Imputation methods replace non-response with estimates of the unobserved...
