“…Furthermore, effects differ between countries, time, industries, and modes of transport, explaining the wide range of estimates found in individual studies. Recent analyses accounting for the identified shortfalls fall into a more narrow range of estimates while providing evidence for many parts of the world: Besides others, Barzin, D'Costa, & Graham (2018) identify the impact of Colombian roads, L. Liu & Zhang (2018) study the high speed rail construction in China, and Arbués, Baños, & Mayor (2015) in Spain as well as Börjesson, Isacsson, Andersson, & Anderstig (2019) in Sweden focus on European countries. All authors find positive effects on production output and employment, as do several studies for the German case: The reports by Bertenrath, Thöne, & Walther (2006) and Barabas et al (2010) provide extensive background information as well as estimation results that are close to the findings of the mentioned meta-analyses.…”
