Czechoslovakia was the first industrialized economy to substantially increase tariffs after the First World War. At that time, Czechoslovakia was highly export-oriented, with a large trade surplus in industrial goods. We argue that the introduction of tariffs was a consequence of the ethnically heterogeneous structure of the economy. German capital controlled the highly export-oriented light and consumer goods industries; Czech capital dominated in industries that were far less export-oriented or even import-competing, such as machinery, transportation equipment, and electrical goods. Trade and exchange-rate policy preferences of both groups clearly differed; however, the policy decision-making process (at least until 1926) was completely controlled by Czechoslovaks and Czech capital, explicitly committed to a nationalist takeover of Czechoslovakia's economy. This is why it was possible to implement an exchange rate and trade policy that ran contrary to theoretical expectations based on the general (national aggregate) indicators of the national economy.
