Technical Efficiency of Mango in Vietnam

Abstract

The paper employed a Cobb-Douglas stochastic production frontier function to estimate the level of technical efficiency. The results of the analysis showed that cropping season of mango growers have been round year. Difference of the study compared to past researches related to tropical fruits analyzed efficiency of three seasons instead of only focusing on efficiency of one season or total a year. The findings revealed that season 3 ranked first in terms of technical efficiency (55.82%), followed by season 1 (54.84%) and then season 2 (49.38%). Furthermore, the input variables that explained technical efficiency were pesticide, fungicide, fertilizer (root), fertilizer (leaf) and labor in season 1; pesticide, fungicide, fertilizer (leaf) and labor in season 2; and pesticide, fungicide, fertilizer (root), fertilizer (leaf) and labor in season 3. In addition, major determinants of socioeconomic characteristics influenced positively on technical efficiency were plant density and land area among three seasons; market access in season 2, and credit access in season 3. By contrast, the constraints to mango production were wrapping bag in season 1, and age and classifying sale in season 2.
