Digital media goods and digital media platforms exhibit cost structures and network effects that imply that price and quantity effects of consumption taxes are qualitatively different compared to what we typically find for physical goods. For instance, in most European countries and US states,...

We examine drivers of cost overruns in Norwegian development projects in the oil and gas sector. The multivariate longitudinal econometric analysis employs a unique and detailed dataset consisting of 80 different projects between 2000 and 2015. Among the significant results, we find that the...
