Tomasz Michalski, Associate Professor at HEC Paris (Economics & Decision Sciences Department), is the co-author of a research article entitled : Do countries falsify economic data strategically? In this video he argues that the falsification of budget data by Greece is not just a one off case situation, but that it has also occurred in Argentina and China. There are also suspicions regarding developed countries. Tomasz Michalski denounces the lack of transparency of statistical agencies and even Central banks, whose numbers produced are very influential on public policy and also public opinion. He therefore calls for a democratization of the process.
