Redistributive preferences, redistribution, and inequality: Evidence from a panel of OECD countries

Kuhn, Andreas - Institut für Volkswirtschaftslehre, … - 2012

This paper describes individuals' inequality perceptions, distributional norms, and redistributive preferences in a … inequality and redistribution. Not surprisingly, the effective level of redistribution (after tax-and-transfer inequality) is … objective dimension of inequality and redistribution are, at least partially, linked with individuals' political preferences and …

Robust performance hypothesis testing with the variance

Ledoit, Olivier; Wolf, Michael - Institut für Volkswirtschaftslehre, … - 2010

Applied researchers often test for the difference of the variance of two investment strategies; in particular, when the investment strategies under consideration aim to implement the global minimum variance portfolio. A popular tool to this end is the F-test for the equality of variances....

A practical two-step method for testing moment inequalities

Shaikh, Azeem M.; Wolf, Michael; Romano, Joseph P. - Institut für Volkswirtschaftslehre, … - 2012

This paper considers the problem of testing a finite number of moment inequalities. We propose a two-step approach. In the first step, a confidence region for the moments is constructed. In the second step, this set is used to provide information about which moments are “negative.” A...

Improving efficiency through consolidation of jurisdictions? Evidence from the cantons of Switzerland

Widmer, Philippe K.; Elias, George; Zweifel, Peter - Institut für Volkswirtschaftslehre, … - 2012

The purpose of this paper is to analyze the optimal scale of local jurisdictions (cantons) in Switzerland applying Data Envelopment Analysis (DEA) to the years 2000 to 2004. Aggregate output performance indicators for four local government activities (administration, education, health, and...

Bootstrap joint prediction regions

Wolf, Michael; Wunderli, Dan - Institut für Volkswirtschaftslehre, … - 2012

Many statistical applications require the forecast of a random variable of interest over several periods into the future. The sequence of individual forecasts, one period at a time, is called a path forecast, where the term path refers to the sequence of individual future realizations of the...

Controlling the danger of false discoveries in estimating multiple treatment effects

Wunderli, Dan - Institut für Volkswirtschaftslehre, … - 2012

I expose the risk of false discoveries in the context of multiple treatment effects. A false discovery is a nonexistent effect that is falsely labeled as statistically significant by its individual t-value. Labeling nonexistent effects as statistically significant has wide-ranging academic and...

The effectiveness of public sponsored training revisited: The importance of data and methodological choices

Biewen, Martin; Osikominu, Aderonke; Fitzenberger, Bernd; … - Institut für Volkswirtschaftslehre, … - 2012

As the first, substantive contribution, this paper revisits the effectiveness of two widely used public sponsored training programs, the first one focusing on intensive occupational training and the second one on short-term activation and job entry. We use an exceptionally rich administrative...

Empirical Likelihood in Count Data Models: The Case of Endogenous Regressors

Boes, Stefan - Institut für Volkswirtschaftslehre, … - 2004

Recent advances in the econometric modelling of count data have often been based on the generalized method of moments (GMM). However, the two-step GMM procedure may perform poorly in small samples, and several empirical likelihood-based estimators have been suggested alternatively. In this paper...

Public Good Provision in a Federalist Country: Tiebout Competition, Fiscal Equalization, and Incentives for Efficiency in Switzerland

Widmer, Philippe K.; Zweifel, Peter - Institut für Volkswirtschaftslehre, … - 2008

The purpose of this paper is twofold. First, it measures the efficiency in the provision of public goods by local jurisdictions applying Data Envelopment Analysis (DEA). Second, it relates ef- ficiency scores to a fiscal equalization scheme designed to mitigate the negative consequences of...

Nonparametric Analysis of Treatment Effects in Ordered Response Models

Boes, Stefan - Institut für Volkswirtschaftslehre, … - 2007

This paper deals with the identification of treatment effects when the outcome variable is ordered. If outcomes are measured ordinally, previously developed methods to investigate the impact of an endogenous binary regressor on average outcomes cannot be applied as the expectation of an ordered...
