Below 4 equations for calculation of wages in Latvia (ALGA, EUR) are given, depending on productivity (PRODUKTIVITATE, thsd EUR), price level (CENA), unemployment rate (BEZDARBS, %) and ratio of GDP of Latvia and the EU (IKP_ATTIECIBA). Which equation would you use, why (for justification use all the indicators known from the lectures)? (t-stat0,05;14 = 2,14; t-stat0,05;15 = 2,13; t-stat0,05;16 = 2,12; F-stat0,05;3;13 = 3,29; F-stat0,05;2;13 = 3,63; F-stat0,05;2;14 = 3,59)
