Abstract

The aim of this article was to present a review of research on measuring the multiplier in agricultural development. Firstly, based on the literature of the subject, several selected results of the analyses and the conclusions that emerge from this research are presented. Two methods are further discussed. The first is a social accounting matrix (SAM), which enables calculating the value of multipliers for each country. The second method discussed is the input-output model, which includes the IMPLAN model. This method allows estimating regional input-output tables, calculating multipliers, and analysing the impact of industry. The presented results indicate that in smaller and more open economies the value of the multiplier is lower than in larger economies. It can also be noted that among researchers there is no agreement concerning the size of the multiplier. / Synopsis. Celem artykułu było zaprezentowanie przeglądu badań na temat pomiaru mnożnika w rozwoju rolnictwa. Na początku, na podstawie literatury przedmiotu, przedstawiono kilka wybranych wyników analiz oraz wnioski, jakie z nich wypływają. Następnie szerzej omówiono dwie metody. Pierwsza z nich to macierz rachunkowości społecznej (SAM), dzięki której można obliczyć wartości mnożników dla poszczególnych krajów. Natomiast druga omówiona metoda to model input-output (przepływów międzygałęziowych), do której zalicza się model IMPLAN. Metoda ta pozwala oszacować regionalne tabele przepływów międzygałęziowych, obliczyć mnożniki oraz dokonać analizy wpływu przemysłu. Zaprezentowane wyniki badań pozwalają stwierdzić, że w gospodarkach mniejszych, które są bardziej otwarte, wielkość mnożnika jest niższa niż w gospodarkach większych. Można również zauważyć, że wśród badaczy nie ma zgodności co do wielkości mnożników.
