Time is Money - The Influence of Parenthood Timing on Wages

This paper studies the effect of parenthood timing on future wages. Using data from the German Socio-Economic Panel (SOEP), we employ an instrumental variable approach to identify the causal effect of delaying parenthood on wages of mothers and fathers. Consistent with previous studies, we provide evidence for a positive delaying effect on wages. We further study the underlying mechanisms of the wage ...

Sooner or Later - Economic Insecurity and the Timing of First Birth

Does economic insecurity delay fertility? Using data from the German Socio-Economic Panel (SOEP) for the years 2001-2011, the impact of economic insecurity on the timing of first birth is examined. Focusing on the timing decision within a career context, different measures of insecurity are analyzed. These include subjective and objective influences on the individual and on more aggregate levels. Results ...

Public versus Private Education with Risky Human Capital

This paper studies the long-run macroeconomic, distributional and welfare effects of tuition policy and student loans. We therefore form a rich model of risky human capital investment based on the seminal work of Heckman, Lochner and Taber (1998). We extend their original model by variable labor supply, borrowing constraints, idiosyncratic wage risk, uncertain life-span, and multiple schooling decisions. ...

The Selection of Pay Referents: Potential Patterns and Impacts on Life Satisfaction

Despite the relatively extensive research on pay levels and the consequences of income disparities, little is known about which reference groups people choose for comparative evaluation of personal income and why different selection patterns emerge. The aim of this paper is to dig deeper for answers to the following three questions: (1) What are the most important reference groups for income comparisons? ...

Measuring the Selection of Pay Referents - A Methodological Analysis of the Questions on Pay Referents in the 2008 and 2009 Pretest Modules

Income comparisons are among the key mechanisms used to explain satisfaction and happiness, among other outcomes. Yet progress on the questions of who people use as social referents and whether differential selection patterns exist can only be made based on valid and reliable measures of pay referents included in large-scale population surveys. The German Socio-Economic Panel Study (SOEP) is pursuing ...

The Social Comparison Scale: Testing the Validity, Reliability, and Applicability of the Iowa-Netherlands Comparison Orientation Measure (INCOM) on the German Population

Social comparisons are an essential source of information about the self. Research in social psychology has shown individual variation in the tendency toward comparison with other people’s opinions and abilities, raising the question of whether social comparisons are driven by psychological dispositions. To test the empirical validity of this proposition, Gibbons and Buunk (1999) created an instrument ...

Individual Differences in Social Comparison and its Consequences for Life Satisfaction: Introducing a Short Scale of the Iowa-Netherlands Comparison Orientation Measure

Research in social psychology has shown individual variation in the tendency to compare one’s own opinions and abilities with those of other people, raising the question of whether social comparisons are psychological dispositions. To test the empirical validity of this proposition, Gibbons and Buunk (1999) created an instrument, the Iowa–Netherlands Comparison Orientation Measure (INCOM), that measures ...

Social Comparison Orientations and their Consequences for Justice Perceptions of Earnings

Recently, research on social comparison orientations (SCOs) has shown remarkable inter-individual variation in people’s tendency to compare themselves with others. Whether this variation bears any consequences for social justice research that assumes social comparisons to be a valuable asset in forming images of just earnings is still an unsolved question. This paper takes up this research challenge ...

Measuring Migrants' Educational Attainment: The CAMCES Tool in the IAB-SOEP Migration Samples

Education is one of the most frequently used variables in social science research. However, it is challenging to measure educational attainment with a high degree of validity and comparability in migrant surveys. In migrant surveys, respondents were educated in various different educational systems. Rather than providing specific response options for the qualifications available in every country of ...
