Tamás Kolosi - president of TÁRKI

Tamás KolosiTamás Kolosi founded TÁRKI in 1985. Previously he worked for the Institute for Social Research (Hungary), where he led several major sociological study on social stratification, social structure, inequalities and value orientations. He formulated a multi-dimensional approach to the inequalities of state socialist system based on large scale empirical surveys. Kolosi developed a theory of late socialist social structure. In his view (state) redistributive and small scale private economy formed a dual system of stratification during the seventies and eighties in Hungary. This is the so-called "L-model" of reform socialist Hungarian society. Meanwhile Kolosi played key role in the introduction of mathematical statistical methods and tools in Hungarian social science. He continued the study of transforming social structure after 1989/1990. His research interest includes the problem of empirical measurement in social sciences, life styles, elite formations during post-communist transition.

He is also turned to be successful businessman in the book publishing industry during the nineties. He is the president and CEO of the Lira és Lant Inc. Between 1989-1990 Tamás Kolosi was advisor to the Prime Minister, Mr. Miklós Németh and between (1998-2002) Mr. Viktor Orbán.

Abstract: The study of social structure represents an important field of sociological research in the European socialist countries. At first, the objective of these studies was to revise the ideological model of society developed during the period of Stalinism, a model that distinguished "two allied classes"--the working class and the peasantry--and "one stratum"--the intelligentsia. Later, as knowledge developed, scientific interest shifted from ideological criticism to exploring and understanding actual social conditions. The present paper briefly touches upon these ideological and scientific developments and makes an attempt to build a model that represents both the system of reproduction and the system of inequality of Hungarian society.

Abstract: The uniqueness of the transition from socialism is that unlike the transitions from authoritarian rules to democracy in the Mediterranean and Latin American countries, it attempts to achieve two transitions simultaneously. Like in transitions from authoritarian regimes it is a political transition whereby political institutions are refashioned, new political elites emerge and political power is redistributed. But this is only one, probably, the easier, transition these countries have to go through. Unlike in transitions from authoritarian regimes, socialist countries also have to engineer an economic transition, which moves their centrally planned or directed economies towards a market economy. The transition from a socialist to a market economy requires new economic institutions, the emerging of new economic elite and a redistribution of property and material well-being. This dual transition will profoundly alter the social structure of these countries. Some people will lose and some will gain power and wealth, some will see their life chances improve dramatically others will see a marked deterioration in their opportunities. What are the social consequences of the transition from socialism? How does the social transition change the social structure? Who is best able to take advantage of new opportunities? What happens to the old elite of Communist cadres? Who is going to become the new elite? What happens to the 'middle class'? These are some of the questions in the forefront of public debate in Eastern Europe and these are the questions this paper is going to address.
