The share of the unregistered economy in Turkey is bigger than any other Organization for Economic Co-operation and Development (OECD) member state, according to a new study.

Elgin believes that the share of Turkey's unrecorded economy rate will be 24 percent in 2023.

However, since the 1990s the problem has fluctuated between 27 and 29 percent. 

Presenting his report, Elgin stressed that the registered economy is not only caused by tax breaks or unregistered employment, adding that online shopping errors, illegal trade, and unpaid...
