We analyze whether the social media popularity of Twitter star scientists, who were identified by Science in a 2014 report, pays off in terms of an increased number of citations. To establish a causal relationship, we use the COVID-19 global pandemic as a quasi-natural experiment exogenously...

This paper empirically studies the impact of decentralization on foreign aid effectiveness. For this purpose, we examine a commonly used empirical growth model, considering aid modality as well as different measures of political and fiscal decentralization. Our panel estimations reveal that...

The majority of theoretical and empirical studies on the relationship between decentralization and corruption argues that the devolution of power might be a feasible instrument to keep corruption at bay. We argue that this result crucially depends on the effectiveness of monitoring bureaucrat's...

This paper examines whether the federal structure of aid-receiving countries matters in explaining aid effectiveness. Following the decentralization theorem, the devolution of powers should increase aid effectiveness, since local decision-makers are better informed about local needs. At the same...

This paper analyzes the impact of political and fiscal decentralization on regional inequalities using a unique data set which covers 56 countries at different stages of economic develop-ment. Cross-section and panel data estimations show that decentralization decreases regional inequalities in...

This paper studies the impact of decentralization on the shadow economy. We argue that decentralization may decrease the size of the shadow economy mainly through two transmission channels: (1) Decentralization enhancing public sector efficiency (efficiency effect), and (2) decentralization...

We study how natural-resource rents affect the risk of internal conflict within countries and how the federal structure of countries influences this relationship. Natural-resource abundance may induce excessive rent-seeking and thus increase the risk of internal conflict. Fiscal and political...

We study the effect of international trade and freeness of trade (openness) on interregional inequality within countries. We estimate a model derived from a structural economic-geography approach in which interregional inequality depends on weighted trade shares and trade costs. In addition to...

This paper provides a new data set of regional income inequalities within countries based on satellite nighttime light data. We first empirically study the relationship between luminosity data and regional incomes for those countries where regional income data are available. We subsequently use...

We study the link between subnational capital cities and urban development using a global data set of hundreds of first-order administrative and capital city reforms from 1987 until 2018. We show that gaining subnational capital status has a sizable effect on city growth in the medium run. We...
