This paper documents the recent performance of European electronic purses. It presents data on 16 such schemes, and compares their penetration and usage rates. These rates are shown to differ substantially. A number of schemes are doing increasingly well and in all probability are here to stay....

One of the most important results of theoretical research on currency systems is that spacing denominations apart by a factor of two is better than a factor of three as this lowers the average number of notes and coins exchanged in transactions. These theoretical studies also claim that an...

We investigate the impact of local banking market concentration on small and medium-sized enterprises' access to finance in Ukraine, as an under-researched case of a country where crime and corruption rates are high. We combine firm-level observations from the EBRD's BEEPS survey with unique,...
