This paper explores how improved internet infrastructure impacts supply chains and economic activity, focusing on Türkiye. Using the expansion of fiber-optic networks and firm-to-firm transaction data, we find that better connectivity shifts input sourcing to well-connected regions and...

We show that the creation of the first integrated pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that interregional trade was strongly influenced by...

We show that the creation of the first integrated multi-modal pan-European transport network during Roman times influences economic integration over two millennia. Drawing on spatially highly disaggregated data on excavated Roman ceramics, we document that contemporary interregional trade was...

This paper analyses the effect of international borders and of trade agreements at international borders on subnational (i.e. regional) growth. We construct an extensive panel dataset covering 1,350 regions in 86 countries worldwide between 1950 and 2017. Our results show that international...

This paper presents three approaches to the evaluation of cross-border transport infrastructure in the Greater Mekong Subregion (GMS). First, it estimates benefit-cost ratios for selected segments of economic corridors. The results indicate differing degrees of economic viability among different...

We present a novel two-stage gravity specification with period-varying bilateral trade cost terms. We test our specification to confirm the benchmark result on declining international distance elasticities over time, using two new data sets. Analyzing period-varying bilateral trade cost derived...

Fears are widespread that Mercosur integration leads to further concentration of economic activity in Brazil's industrial centres, while the periphery of Brazil, including the Northeast, will find it more difficult to catch up economically. We evaluate such fears in several steps: - First, we...

In Africa there has been an immense effort in the past, continuing into the present, to unite politically and to build numerous economic integration areas. In this paper we discuss the reasons for the existence of this phenomenon in Africa which we call the drive to political and economic...

Border regions and border effects currently attract a lot of attention in political practice and economic research. Substantial interest in regions located along the frontiers of integrating countries is predominantly inspired by the presumption that their specific geographic position might...

Im Zuge der Osterweiterung der Europäischen Union eröffnen sich für die Beitrittskandidatenländer gute Möglichkeiten, wirtschaftliche Aktivitäten aus Westeuropa und anderswo zu attrahieren und im Pro-Kopf-Einkommen aufzuholen. Der Aufholprozess der Beitrittsländer wird jedoch von...
