Two books related to the family companies’ management have been translated and published in Bulgarian due to the financial support of Petar Mandjoukov and as a result of the authors’ - Denise Kenyon-Rouvine and Jozef Lievens - consent:
"Family Businesses Management" by Jozef Lievens 
"This book has been written with the firm conviction that it would help those who believe and want to organize their company in accordance with the family business principle; to all Bulgarians who are ready to bind the way they carry out and perform their family businesses to their names, to the responsibility imposed above, in their striving to be both men of property and more useful for the others. And above all, it is about the family business morality and responsibility!”
Petar Mandjoukov
