1984
Stiean Sriboonruang
This study attempted to compare the economic efficiency of two groups of glutinous rice farms (small and large) in rainfed areas under two types of farm management (family labor intensive and hired labor intensive). The first group comprised farms which used family labor and cultivated land equal to or less than 5.3 rai. The second group of farms used hired labor and cultivated more than 5.3 rai of land. In addition, the returns to scale of glutinous rice production were also studied to find the optimum farm size of glutinous rice farm in Amphoe Maetha of Lumphun Province in 1984. The study surveyed 99 farmers who grew glutinous rice during the rainy season. The Cobb-Douglas profit function model of Lau and Yotopoulos (1971, 1973) was used as a tool for the analysis. It was found that the production of glutinous rice was characterized by constant returns to scale
