The main goal of the research project outlined in the present paper is to initiate systematic monitoring of the size and dynamics of the hidden economy in Bulgaria (HEM). The project envisions conducting a series of representative surveys of the country's adult population and of the business sector at three-month intervals. This will make it possible not only to examine the dynamics of the problem, but also to collect reliable information about the differences in the attitudes of the general population and the business community to the manifestations and reasons for the development of the hidden economy in this country
