Does Expanding Regional Train Service Reduce Air Pollution?

We assess how regional rail service affects air pollution in Germany, where rail service is procured in auctions or negotiations. We argue that the procurement mode is plausibly exogenous, and show that auctions deliver stronger rail service growth than negotiations. Instrumenting rail service growth with procurement mode, we find that increasing rail service by 10% reduces carbon monoxide and nitrogen ...

From Strangers to Acquaintances? Interviewer Continuity and Socially Desirable Responses in Panel Surveys

In many panel surveys that rely on face-to-face interviewing, interviewers are repeatedly allocated to the same respondents in each wave. Researchers and fieldwork agencies argue that interviewer continuity can contribute to the quality of the data collected, for instance, by reducing panel attrition. However, there is almost no empirical evidence focusing on the effects of growing familiarity between ...

To design policies and programs that meet these needs, ...

Personalized Feedback in Web Surveys: Does it Affect Respondents' Motivation and Data Quality?

Web surveys technically allow providing feedback to the respondents based on their previous responses. This personalized feedback may increase respondents’ motivation and possibly the accuracy of responses. While past studies mainly concentrate on the effects of providing study results on future response rates, thus far survey research lacks theoretical and empirical contributions on the effects of ...

Comparing Self-Reported and Partnership-Inferred Sexual Orientation in Household Surveys

Research comparing heterosexuals with bisexuals and homosexuals in economics and the social sciences typically relies on two strategies to identify sexual orientation in existing survey data of general populations. Probing respondents to self-report their sexual orientation is generally considered the preferred option. Since self-reports are unavailable in most large multidisciplinary surveys, often ...
