There is no single correct theory of economics

Abstract

This text was prepared to celebrate the 9th Congress of Polish Economists, which took place in Warsaw at the end of November 2013. As demonstrated by the history of congresses of Polish economists, the congresses were held in highly diverse socio-economic and political conditions; therefore their central ideas were kind of the sign of the times. The Congress was held in the period in which the economic situation of individual countries and the world was formed primarily by factors which were the consequence of the global financial crisis that began in the years 2007/2008 in the U.S. and evolved into the economic crisis and finally into the debt crisis, which still plagues many countries.
