The IMF published its latest growth report before the outset of the regular sessions of the IMF/World Bank, which are held in Bali, Indonesia.
Slovenia is forecast to have a 5.8% unemployment rate in 2018 and 5.4% in 2019. Both figures are by 0.1 points lower than in spring.
Inflation is forecast to hit 2.1% this year, up from 1.7% from the previous forecast, while the figure for 2019 was left unchanged at 2%.
The IMF's forecast is a bit above that of Slovenia's Institute for Macroeconomic Analysis and Development (IMAD), which significantly downgraded its outlook in September.
According to IMAD, Slovenia's economy will grow at 4.4% in real terms this year, down 0.7 points from the spring forecast.
IMAD's forecast for 2019 was meanwhile downgraded to 3.7% from 3.8%.
Both the IMF and IMAD's forecasts are within the range forecast by the Slovenian central bank in August, when it anticipated a 4.0% to 4.5% growth rate for 2018.
