The document analyzes the relationship between costs and the size of economic units that supply agricultural inputs in Romania. It examines the first 10 largest input supplier firms and compares them to 15 smaller firms. The results show that larger suppliers benefit from economies of scale but choose to pass those savings on to customers in the form of lower prices in order to gain market share and brand loyalty. While not a fully representative sample, the study highlights how scale impacts costs and allows firms to better position themselves in the agricultural input market.
