Diskussionsbeitrag / Discussion. Paper Coin: Migration and Seigniorage within the Euro Area

Summary The introduction of the euro coins in 2002 presented a unique opportunity to study the crossborder migration and the mixing process of coins in different euro-area countries. This note analyses how many euro coins flow from and into Germany and which composition of coins is to be expected in the long run. A simple model of coin migration is formulated and calibrated for Q1 coins. The ratio of German coins circulating in Germany is likely to settle around 50%if past growth of coin volumes continues. In contrast to banknotes, allocation of coin seigniorage depends on national coin issuance. Different national growth rates of coin volumes have important implications for coin seigniorage.
