In addition to academic papers and policy reports (a list is in my CV), I collaborate with international organisations as well as media. A  few recent examples follow.

  • I accepted an invitation to take part in the European Parliamnet’s TAX3 committee public hearing on “The evaluation of the Tax Gap” on 24 January 2019. The video and other documents are available here.image.png
  • My research has been repeatedly cited by leading newspapers including The Economist:
    • The Economist in January 2019: “Alex Cobham of the Tax Justice Network and Petr Jansky of Charles University, Prague, propose two indicators: one based on mismatches between where multinationals report their profits and where their real activity occurs, and another that is a measure of undeclared offshore assets.”
    • The Economist in February 2019: “An analysis of American multinationals and their international subsidiaries in 2017 found that the share of profits declared elsewhere for tax purposes had risen from 5-10% in the 1990s to 25%. Poor countries are hit hardest because they rely more on corporate tax revenues than rich countries, and because international tax rules, originally crafted to suit advanced economies, are stacked against them.”
    • The Economist in November 2011: “A recent independent study by three doctoral students from Charles University—Jana Chvalkovská, Petr Janský and Jiří Skuhrovec—is alarming. Their “zIndex” of public procurement shows that 67% of the €13.7billion ($19 billion) spent between 2006 and 2010 is not tracked in the government’s official procurement database. About 14 % of all tenders during that period (worth some €2 billion) only had one bidder, and none meet the criteria of the OECD and the Regional Development Ministry.”


  • I gave an interview about research of tax havens in Counting the cost at Al Jazeera on 7 November 2019 (his interview starts at 17:45). I discussed the importance of foreign direct investment and tax havens, including a recent IMF working paper. I also introduced estimates of revenue effects of tax avoidance by multinational enterprises, which we published recently with a colleague Miroslav Palanský in an academic journal International Tax and Public Finance (Estimating the Scale of Profit Shifting and Tax Revenue Losses Related to Foreign Direct Investment).image.png
