The “Great Recession” has painfully demonstrated the impact of real estate prices on real economic activity. Hence, close examination of real estate price changes is important for business cycle analysis and economic policy. However, most real estate price indices for Germany either exhibit...

Economists have been noting for decades that Consumer Price Index (CPI) in the developed countries is overstating inflation by 0,5−2,0% per year. A significant part of the bias is due to the presence of technology products and differentiated products in the CPI basket. An increase share of...

Die übliche Schätzfunktion zur Bestimmung der relativen Lohndifferenz mittels Dummyvariable in einer log-linearen Regressionsfunktion ist inkonsistent, falls gruppenspezifische Heteroskedastie vorliegt. Die Richtung und Größenordnung der Verzerrung wird abgeleitet. Ein Fallbeispiel zur...

Two distribution free estimators are proposed to estimate the mean of a dependent variable after fitting a semiparametric two-part heteroscedastic regression model to a transformation of the dependent variable. We show that the proposed estimators are consistent and have asymptotic normal...

Hedonic methods are a prominent approach in the construction of quality-adjusted price indexes. This paper shows that the process of computing such indexes is substantially simplified if arithmetic (geometric) price indexes are computed based on exponential (log-linear) hedonic functions...

Questions about monetary variables (such as income, wealth or savings) are key components of questionnaires on household finances. However, missing information on such sensitive topics is a well-known phenomenon which can seriously bias any inference based only on complete-case analysis. Many...

The current literature often values intangible goods like cultural heritage by applying stated preference methods. In recent years, however, the increasing availability of large databases on real estate transactions and listed prices has opened up new research possibilities and has reduced...

This paper presents a novel framework for selecting socially responsible investment (SRI) portfolios. The Hedonic Price Method (HPM) is applied to obtain an evaluation of SRI criteria that is integrated into a multi-objective mathematical programming model. The HPM breaks away from the...

In this article, we combine data from the housing market with data from a victimization survey to estimate the effect of crime perception on housing prices in the City of Barcelona from 2004 to 2006. Using dwelling data and a hedonic price model (using both OLS and quantile regressions), in the...
