The Early Bird Catches the Worm! Setting a Deadline for Online Panel Recruitment Incentives

The literature on the effects of incentives in survey research is vast and covers a diversity of survey modes. The mode of probability-based online panels, however, is still young and so is research into how to best recruit sample units into the panel. This paper sheds light on the effectiveness of a specific type of incentive in this context: a monetary incentive that is paid conditionally upon panel ...

The Productivity Shock in Business Services

In Germany, the productivity of professional services, a sector dominated by SME, declined by 40 percent between 1995 and 2014. Similar developments can be observed in several other European economies. Using a German dataset with 700,000 firm-level observations, we analyze this largely undiscovered phenomenon in professional services, the fourth largest sector of the business economy in the EU-15, ...

Sanctions against Russian Oligarchs also Affect Their Companies

In February 2022, the EU Commission announced economic sanctions against Russian oligarchs. The goal was to exert pressure on the Kremlin: initially to stop deploying troops to the Donetsk and Luhansk regions and ultimately to end its attack on Ukraine. The present report investigates how these sanctions affect companies headed by Russian oligarchs. The empirical findings show that after sanctions ...

Educational Selectivity and Immigrants’ Labour Market Performance in Europe

This article depicts the selectivity profiles of first-generation immigrants of multiple origins in 18 European destinations and investigates whether educational selectivity is relevant to their labour market performance. The theoretical account starts from the premise that the relative position individuals occupy in the educational distribution of their origin country represents—frequently unmeasured—characteristics ...

Does Green Public Procurement Trigger Environmental Innovations?

Green public procurement has gained high political priority and is argued to be an effective demand-side policy to trigger environmental innovations. However, the empirical evidence on its innovation impact is limited. We construct a novel firm-level dataset to investigate the effect of winning public procurement tenders with additional environmental award criteria on firms’ introduction of environmental ...

Measurement Equivalence in Probability and Nonprobability Online Panels

Nonprobability online panels are commonly used in the social sciences as a fast and inexpensive way of collecting data in contrast to more expensive probability-based panels. Given their ubiquitous use in social science research, a great deal of research is being undertaken to assess the properties of nonprobability panels relative to probability ones. Much of this research focuses on selection bias, ...

Mentoring as a Grassroots Effort for Integrating Refugees – Evidence from a Randomised Field Experiment

About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to support refugee integration in hosting communities. This study examines a network intervention for refugees in collaboration with a social start-up whose mission is to match refugees and local volunteers to form friendships. We apply ...

Stranded Assets in the Coal Export Industry? The Case of the Australian Galilee Basin

Steam coal exporters face increasing uncertainty about future coal demand and risks of asset stranding. Nevertheless, new export-oriented coal mine projects are still brought forward. In this study, we use the coal sector model COALMOD-World to assess the economic prospects of investments in the export-oriented steam coal sector, and in particular of coal mines in the Galilee Basin, Australia. We parameterize ...
