By the mid-1910s Schumpeter had established himself as one of the most brilliant economists of his generation and, like other well-known economists in the Austro-Hungarian Empire, he hoped for a prominent political position, such as the minister of finance or the emperor`s economic adviser. During World War I, Schumpeter wrote a series of memorandums that circulated among the Empire`s elite and through which he hoped to establish himself as a candidate for political office. The various measures proposed by Schumpeter in these memorandums are now of little interest, for example the fact that the Empire should not enter into a customs union with its powerful neighbour, Germany. But what is more interesting is that they give an overview of Schumpeter`s political views when he was in his thirties. Schumpeter`s political profile at that time can be described as a royalist, deeply conservative and an admirer of British-style Tory democracy. A second risk of regionalism and bilateralism is the creation of a complex trading system, as Baldwin asserts. There are agreements within large blocks of countries in the same region, such as the north and south blocs in America, Europe and Asia, which overlap with many other peripheral countries. Many members of these large growing blocks have business between them. For example, Mexico is part of the North American Free Trade Agreement (NAFTA) and a free trade agreement with the EU and others. If we mention Schumpeter`s article on social classes, we must also say something about two of his other famous studies in sociology: “The fiscal crisis of the tax state” (1918) and “The sociology of imperialism” (1991). The first study can be described as a pioneering work in tax sociology, which focuses on the situation in Austria shortly after the First World War, but also attempts to formulate some general statements on the relationship between taxation and society.
Schumpeter, for example, proposes that the state collapse if citizens increasingly demand public subsidies, but are not willing to pay them through higher and higher taxes. In the article on imperialism, Schumpeter asserts that imperialism emerges from an unsustainable social situation in capitalism; and whatever imperialist forms still exist, an atavism and an agent of feudal society. Schumpeter`s famous definition of imperialism is: “Imperialism is the state`s predisposition to unlimited violent expansion.” Martin et al. (2008) notes that multilateral trade opening increases the likelihood of conflict by reducing bilateral trade and hence the cost of bilateral conflict. This indicates that the ATP has a positive role to play in reducing conflict. Vicard (2012) believes that the UC and the CM reduce the likelihood of a war between members, but not the flatter PTAs. He and Martin et al. (2012) find that countries where the frequency of past wars are more frequent are more likely to sign ATPs. To illustrate what economists can do through sociology, Schumpeter wrote an article on social classes in 1991, which is still often mentioned. Schumpeter begins by drawing a clear line between how the concept of class is used in economics and sociology.
In economics, Schumpeter says, class is basically used as a category (z.B. salaried/non-salary), whereas in sociology, class is considered a living reality.
