This article investigates the use of the configurational variable, which deals with the city form-space relations regarding transportation issues, to study spatial segregation and urban accessibility in four Brazilian cities (Belém, Manaus, Recife and São Paulo), with a focus in precarious...

This paper experimentally studies two simple interventions aimed at increasing public goods provision in settings in which accurate feedback about contributions is not available. The first intervention aims to exploit lying aversion by requiring subjects to send a non-verifiable ex post...

I empirically assess the importance of socially interdependent origin cultures as opposed to socially independent ones for network effects in inter-national migration. I propose that societies that emphasise collectivist behaviour accumulate larger levels of communityspecific social capital than...

Despite numerous studies on the social and political impact of refugees in Europe, we have very little systematic evidence on the impact of refugee settlement on social cohesion in the developing world. Using data gathered in Northern Lebanon, we show that increased salience of the "refugee...

This study introduces a new measure of urban centrality. It identifies distinct urban structures from different spatial patterns of jobs and resident population. The proposed urban centrality index constitutes an extension of the spatial separation index (MIDELFART-KNARVIK et al., 2000). It is...

We present a model for the dynamics of networks in which edges represent positions in organizations, holders of which are connected to each other when the positions belong to the same organization. Once a vacancy is opened, the new employee can be hired from the current network. In particular,...

This report describes the subject, design and realization of the study "Entscheidungsträger in Deutschland: Werte und Einstellungen". The survey focusses on political attitudes, behavioral norms, motives and biographies of leaders in politics, public administration, business as well as in the...

Taxpayers often view tax rules and filing processes as complicated. In this paper I study whether the perceived tax uncertainty among peers leads to a reduction of voluntary tax compliance. I find strong supportive evidence for this hypothesis using a survey experiment for a large representative...

This study deals with the impact of the 2015 European Refugee Crisis on the ethnic identity of resident migrants in Germany. To derive plausibly causal estimates, I exploit the quasiexperimental setting in Germany, by which refugees are allocated to different counties by state authorities...

This paper studies the effect of immigrants' national identity on integration in an inter-generational context. Economic theory predicts that the origin country identity of immigrants affects their children's integration through its effects on social network choices and incentives to invest in...
