Economy of Liechtenstein
The economy of Liechtenstein is based roughly equally on services (especially financial services) and industry, with a small but significant agricultural sector. The country participates in a customs union with Switzerland and uses the Swiss franc as its national currency. It imports more than 85% of its energy requirements. Liechtenstein has been a member of the European Free Trade Association (EFTA) since 1991 (previously its interests had been represented by Switzerland). It also has been a member of the European Economic Area (EEA) since May 1995 and participates in the Schengen Agreement for passport-free intra-European travel.
Switzerland as a federal state
Some of the first acts of the new Federal Assembly were to unify and standardize daily life in the country. In 1849 a uniform postal service was established. In 1850 a single currency was imposed to replace the cantonal currencies, while all customs between cantons were abolished. In 1851 the telegraph was organized, while all weights and measures were unified. In 1868 the metric system was allowed and in 1875 declared obligatory and universal. In 1854 roads and canals taken in hand were taken under federal control. The Federal Polytechnic wasn't opened until 1855 in Zurich, though the Federal university authorized by the new constitution has not yet been set up.
