We show with the aid of pooled OLS estimations that investments in improved road infrastructure have the potential to signficantly reduce transport costs. However, this result can only be clearly con rmed for industrial countries and is of primary importance for production and transportation of...

We investigate the regional distribution of the COVID-19 outbreak in Germany. We use a novel digital mobility dataset, that traces the undertaken trips on Easter Sunday 2020 and instrument them with regional accessibility as measured by the regional road infrastructure of Germany's 401 NUTS III...

We study in the laboratory the impact of private information revelation on the selection of partners when forming individual networks. Our experiment combines a "network game" and a "public-good game". In the network game, individuals decide with whom to form a link with, while in the...

The question to what extent social environment affects how individuals govern their groups, has received no special academic attention, yet. Within the framework of a ten-period public goods experi&ment we analyse how social identity affects subjects ́choice of punishment: They may either...

In a public-good experiment with heterogeneous endowments, we investigate if and how the contribution level as well as the previously observed "fair-share" rule of equal contributions relative to oneś endowment (Hofmeyr et al., 2007; Keser et al., 2014) may be influenced by minimum-contribution...

We develop and test a theory of voting and turnout decisions that integrates self-interest, social preferences, and expressive motives. Our model implies that if pocketbook benefits are relevant, voters either perceive their impact on the outcome to be non-negligible, or expressive motivations...

Individuals who share a common identity show persistently elevated contributions to public goods. Yet, so far the factors that actually trigger this welfare enhancement are not precisely understood. We investigate two channels: (1) subjects ́expectations on group members ́cooperativeness and...

This article analyzes how the anticipation of peer-punishment affects cooperativeness in the provision of public goods under social identity. For this purpose we conduct one-shot public good games with induced social identity and implement in-group, out-group and random matching protocols. Our...
