ECONOMETRIC ANALYSIS OF VOLUMES OF IMPORT OF THE REPUBLIC OF BELARUS

The article obtained econometric models of time series in terms of imports of the Republic of Belarus according to quarterly data in the period from 2013 to 2018. Exponential smoothing model and multiplicative model are constructed. Also, a forecast was made of import volumes in terms of value for the 4th quarter of 2018.

THE ECONOMETRIC ANALYSIS OF THE DYNAMICS OF ETHEREUM IN THE SHORT-TERM PERIOD

The article presents an econometric analysis of the effect of stock indicators, such as Comex Gold futures, Dow Jones Industrial Average index and NASDAQ Composite, on the Ethereum cryptocurrency dynamics in the 100-day period. As part of the study, an econometric model of the dynamics of e-currency was built. The survey results show that when the Comex gold futures price changes by 1% on average, the Ethereum price changes by 5.01% in the same direction, when the Dow Jones Industrial Average index changes by 1%, the Ethereum price is 10.897%, and when the NASDAQ Composite index changes, the Ethereum price will change in the opposite direction to 3.59%
