Modelling of production relations in the Lithuanian economy

Šiame darbe pristatomas metodas, leidžiantis analizuoti, kaip keičiasi kiekvienos iš ūkio šakų kainų lygis, kintant gamybos veiksnių kiekiams. Kiekvienam ūkio sektoriui buvo įvertinta Cobb–Douglas gamybos funkcija, kuria remiantis prognozuota produkcijos apimtis. Naudojantis tarpšakinio balanso uždavinių sprendimais, modeliuoti Lietuvos ekonomikai aktualūs scenarijai ir nagrinėta, kaip darbo ir kapitalo pokyčiai daro įtaka kainoms.This paper presents a method for the analysis of price index changes in each branch of the country’s economy given changes in production factors. Cobb–Douglas production functions were evaluated for each sector separately enabling the forecasting of production quantities. The country’s total production function was estimated using conditional regression. Later, an inter-branch balance problem of price and production volume relationship evaluation was solved using a Lithuanian input–output table. Finally, combining the estimated production functions and estimated price–output relationship, Lithuanian economy-relevant scenarios of re-emigration and retail chain Lidl investment were analysed
