The European Union Statistics on Income and Living Conditions (EU-SILC) is a rotational panel provided by Eurostat that covers variables with a high potential for comparative European labour market and social research. Unfortunately, its current availability limits its potential research...

Based on the hypothesis that microdata are of crucial importance for internationally competitive economic research and scientific advice in economic and social policy, the authors develop various proposals for an improved data supply for empirical work in Germany.

In order to correct the bias due to unit non-response for the KOF ETH Zurich's business (mail) surveys, we usually use the results of a second (phone) survey by the non-respondents. Taking the case of the survey 2000 on "Organization and Information Technologies" in the Swiss economy, we...

Time-use researchers are typically interested in the time use of individuals, but time use data are samples of person-days. Given day-to-day variation in how people spend their time, this distinction is analytically important. We examine the conditions necessary to make inferences about the time...

The 2003 Survey of Small Business Finances (SSBF) screening interview had significant unit nonresponse and therefore some type of nonresponse adjustment was deemed necessary. The approach used in the 2003 survey differed from that used in previous surveys. The current paper examines the impact...

A specific feature of business conditions surveys describing actual and expected short-term trends of company financial and economic activities is the non-quantitative nature of the relevant data. To facilitate its interpretation and visualisation for various user groups, the respondents'...

In a randomized control trial, the precision of an average treatment effect estimator can be improved either by collecting data on additional individuals, or by collecting additional covariates that predict the outcome variable. We propose the use of pre-experimental data such as a census, or a...

The quality of data on employment income is explored using Tanzanian and Zambian household survey datasets. The extent of missing and implausible income data is assessed and four different methods are applied to impute missing or implausible values. The four imputation methods are also applied...
