生活品質與生產效率: 哥倫比亞咖啡、玉米及樹薯農家之實證分析

Abstract

Recently the economic development research have focus not only on the country’s economic performance but also on how economic growth affect the quality of life (QOL), giving more support to economic policies that effectively improve life standards to the society. With this in mind the Colombian government held a National Quality of Life and Efficiency Survey (ENCVE) of more than 10.000 Colombian households covering all the territory collecting information for the QOL and the performance in their occupation. This study tries to use the survey as an empirical evidence that people with good QOL are at the same time more efficient at work. In this study, the technical efficiency (TE) of 712 coffee, 623 corn and 508 cassava farms are estimated using the Stochastic Frontier Analysis (SFA), followed by an Ordinary Least Square (OLS) and the logistic regression analyses to establish a relationship between the calculated efficiency and the reported QOL in the ENCVE. For the coffee farmers, the results show a positive relationship between TE and QOL and the relationship seems to be reinforced in a virtuous cycle. For the corn case, there is no sufficient proof for the cycle. Finally for the cassava farmers, there is no evidence of any relationship between the two. The results also show that the perception of your peers could improve the QOL and the permanent crops could have an advantage providing good efficiency and good QOL simultaneously for the farmers. This implies that in order to enhance the efficiency and QOL in the rural area at the same time, the government subsides could be focused on increasing the equality, fairness and standard of living especially in the permanent crops.
