This note develops a modelling approach for wireless networks driven byfluid traffic models. Introducing traffic sets that follow movement ofsubscribers, the wireless network with time-varying rates is transformedinto a stationary network at these traffic sets, which yields that thedistribution...

I use the quasi experimental nature of the roll-out of the mobile phone network in Mozambique to estimate the impact of search costs on the dispersion of maize prices and transport costs. The introduction of mobile phone services from 1997 to 2009 explains a 4.5-11% percent reduction in price...

We investigate to what extent the roll-out of the mobile phone network in Mozambique reduced transport costs and search costs, and thereby decreased spatial price dispersion and improved market efficiency. Estimations are based on data of transport costs of maize grain and maize market prices....

We measure the impact of search costs on farmers' and traders' transaction prices in Mozambique by investigating to what extent the introduction of mobile phones has affected the margin between recorded maize producer and retail market prices, and by exploring if producers or traders benefit...

We provide novel evidence on the effect of smart phone use on road accidents. We exploit variation in phone usage fees in the Netherlands following a change in European Union (EU) roaming regulations implemented in 2017. The growth rate of mobile data roaming increased substantially after the...

Proponents of the so-called New Economy claim that it entails a structural change of the economy. Such a change, in turn, would require the central bank to rethink its monetary policy to the extent that traditional relationships between inf1ation and economic growth are no longer valid. But such...
