Types of socialism in the context of "Titoism"

The Eastern Bloc, also known as the Communist Bloc (Combloc), the Socialist Bloc, the Workers Bloc, and the Soviet Bloc, was an unofficial coalition of Communist states of Central and Eastern Europe, Asia, Africa, and Latin America that were aligned with the Soviet Union and existed during the Cold War (1947–1991). These states followed the ideology of Marxism–Leninism and various types of socialism, in opposition to the capitalist Western Bloc. The Eastern Bloc was often called the "Second World", whereas the term "First World" referred to the Western Bloc and "Third World" referred to the non-aligned countries that were mainly in Africa, Asia, and Latin America but notably also included former pre-1948 Soviet ally Yugoslavia, which was located in Europe.

In Western Europe, the term Eastern Bloc generally referred to the USSR and Central and Eastern European countries in the Comecon (East Germany, Poland, Czechoslovakia, Hungary, Romania, Bulgaria, and Albania). In Asia, the Eastern Bloc comprised Mongolia, Vietnam, Laos, Kampuchea, North Korea, South Yemen and China. In the Americas, the countries aligned with the Soviet Union included Cuba from 1961 and for limited periods Nicaragua and Grenada.

Criticism of socialism is any critique of socialist economics and socialist models of organization and their feasibility, as well as the political and social implications of adopting such a system. Some critiques are not necessarily directed toward socialism as a system but rather toward the socialist movement, parties, or existing states. Some critics consider socialism to be a purely theoretical concept that should be criticized on theoretical grounds, such as in the economic calculation problem and the socialist calculation debate, while others hold that certain historical examples exist and that they can be criticized on practical grounds. Because there are many types of socialism, most critiques are focused on a specific type of socialism, that of the command economy and the experience of Soviet-type economies that may not apply to all forms of socialism. Different models of socialism conflict with each other over questions of property ownership, economic coordination and how socialism is to be achieved. Critics of specific models of socialism might be advocates of a different type of socialism.

According to the Austrian School economist Ludwig von Mises, an economic system (specifically centralized economic planning) that does not use money, financial calculation, and market pricing would be unable to effectively value capital goods and coordinate production, and therefore in his view socialism is impossible because it lacks the necessary information to perform economic calculation in the first place. Another central argument leveled against socialist systems based on economic planning is based on the use of dispersed knowledge. Socialism is unfeasible in this view because information cannot be aggregated by a central body and effectively used to formulate a plan for an entire economy, because doing so would result in distorted or absent price signals; this is known as the economic calculation problem. Other economists criticize models of socialism based on neoclassical economics for their reliance on the faulty and unrealistic assumptions of economic equilibrium and Pareto efficiency.
