Homothetic efficiency : a non-parametric approach
Heufer, Jan; Hjertstrand, Per - 2014
This article provides a robust non-parametric approach to demand analysis based on a concept called homothetic efficiency. Homotheticity is a useful restriction or assumption but data rarely satisfy testable conditions. To overcome this problem, this article provides a way to estimate homothetic...

Revealed notions of distributive justice II : experimental evidence
Becker, Nicole; Häger, Kirsten; Heufer, Jan - 2013
We report the results of a combination of a dictator experiment with either a “social planner” or a “veil of ignorance” experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer...

Revealed notions of distributive justice I : theory
Becker, Nicole; Häger, Kirsten; Heufer, Jan - 2013
We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. “Dictator games” with varying transfer rates used in Andreoni and...

Consistent subsets : computationally feasible methods to compute the Houtman-Maks-index
Heufer, Jan; Hjertstrand, Per - 2014
We provide two methods to compute the largest subset of a set of observations that is consistent with the Generalised Axiom of Revealed Preference. The algorithm provided by Houtman and Maks (1985) is not comput ationally feasible for larger data sets, while our methods are not limited in that...

Quasiconcave preferences and choices on a probability simplex : a nonparametric analysis
Heufer, Jan - 2010
A nonparametric approach is presented to test whether decisions on a probability simplex could be induced by quasiconcave preferences. Necessary and sufficient conditions are presented. If the answer is affirmative, the methods developed here allow to reconstruct bounds on indifference curves....

Generating random optimising choices
Heufer, Jan - 2012
Generalised Axiom of Revealed Preferences (GARP), that is, they are consistent with utility maximisation. The choices are drawn … from an approximate uniform distribution on the admissible region on each budget which ensures consistency with GARP, based … it can be used to approximate the power of tests for conditions for which GARP is a necessary but not sufficient …

Stochastic dominance and nonparametric comparative revealed risk aversion
Heufer, Jan - 2011
It is shown how to test revealed preference data on choices under uncertainty for consistency with first and second order stochastic dominance (FSD or SSD). The axiom derived for SSD is a necessary and sufficient condition for risk aversion. If an investor is risk averse, stochastic dominance...

WTA-WTP disparity : the role of perceived realism of the valuation setting
Frondel, Manuel; Sommer, Stephan; Tomberg, Lukas - 2019
Based on a survey among more than 5,000 German households and a single-binary choice experiment in which we randomly split the respondents into two groups, this paper elicits both households’ willingness to pay (WTP) for power supply security and their willingness to accept (WTA) compensations...

Measuring energy security : a conceptual note
Frondel, Manuel (contributor);  … - 2008
Along with the oil price, concerns about the security of energy supply have soared once again in recent years. Yet, more than 30 years after the OPEC oil embargo in 1973, energy security still remains a diffuse concept. This paper conceives a statistical indicator that aims at characterizing the...

Measuring energy supply risks : a G7 ranking
Frondel, Manuel; Ritter, Nolan; Schmidt, Christoph M. - 2009
The security of energy supply has again become a similarly hot topic as it was during the oil crises in the 1970s, not least due to the recent historical oil price peaks. In this paper, we analyze the energy security situation of the G7 countries using a statistical risk indicator and empirical...
