(ANSA) - BELGRADE, OCTOBER 16 - The share of the shadow economy in Ukraine reached 47.2 of country's GDP in 2018, a study of the Kyiv International Institute of Sociology revealed, the specialized portal Emerging Europe reported. According to the Institute, the shadow economy amounted to 46.8% of GDP back in 2017 and the construction and retail sectors currently show the highest figures of undeclared economic activity. "The study also found that while 40 per cent of company revenues in the shadow economy remained hidden, close to a third of employees were not registered and 45 per cent of salaries went undeclared," Emerging Europe informed. The results of the study are however contradicting with the official figures from the Ministry of Economic Development and Trade, which stated in July that the shadow economy dropped below 30% of GDP in 2018.
