Non-Response Biases in Surveys of School Children: The Case of the English PISA Samples
Micklewright, John; Schnepf, Sylke V.; Skinner, Chris - Institute for the Study of Labor (IZA) - 2010
We analyse response patterns to an important survey of school children, exploiting rich auxiliary information on respondents' and non-respondents' cognitive ability that is correlated both with response and the learning achievement that the survey aims to measure. The survey is the Programme for...

Bias Corrections for Two-Step Fixed Effects Panel Data Estimators
Fernández-Val, Iván; Vella, Francis - Institute for the Study of Labor (IZA) - 2007
This paper introduces bias-corrected estimators for nonlinear panel data models with both time invariant and time …/selection bias. We then estimate the primary equation by fixed effects including an appropriately constructed control function from … both steps might employ nonlinear fixed effects procedures it is necessary to bias adjust the estimates due to the …

Social Ties and Subjective Performance Evaluations: An Empirical Investigation
Breuer, Kathrin; Nieken, Petra; Sliwka, Dirk - Institute for the Study of Labor (IZA) - 2010
We empirically investigate possible distortions in subjective performance evaluations. A key hypothesis is that evaluations are more upward biased the closer the social ties between supervisor and appraised employee. We test this hypothesis with a company data set from a call center organization...

Wealth Shocks and Health Outcomes: Evidence from Stock Market Fluctuations
Schwandt, Hannes - Institute for the Study of Labor (IZA) - 2014
Do wealth shocks affect the health of the elderly in developed countries? The economic literature is skeptical about such effects which have so far only been found for poor retirees in poor countries. In this paper I show that wealth shocks also matter for the health of wealthy retirees in the...

How to Think About Time-Use Data: What Inferences Can We Make About Long- and Short-Run Time Use from Time Diaries?
Frazis, Harley; Stewart, Jay - Institute for the Study of Labor (IZA) - 2010
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...
