Technical efficiency and agricultural policy: evidence from the tea production in Vietnam

Abstract

The objective of this paper is to apply the stochastic production frontier methodology to a survey database collected in northern Vietnam. Our study finds that the average technical efficiency of tea production is only about 41 %. Among extension policy measures available to farmers, only training on production inputs has an improving impact on technical efficiency. Other features of policy have no significant effect, contrary to the expectation. The adoption of the oldest variety BTrung-Du^is not a source of inefficiency while the effects of other new varieties are insignificant. The results indicate that there is a great potential for improving production efficiency in the region of the study.

A framework to build a resilient supply chain: a case study of Javanese tea in Indonesia

“…On a micro level, agricultural policy is a regulation or guidelines issued by the government which is expected to improve the livelihood of smallholders by improving the utilization of existing technology, developing managerial skills of smallholders, and providing them with information on new technology, new varieties and more efficient farming practices. On a wider scale, it is also expected to connect the smallholders to markets and other stakeholders in the agricultural value chain (Birner et al, 2009;Davis et al, 2012;Dinar et al, 2007;Nguyen-Van and To-The, 2016;Owens et al, 2003;Ragasa et al, 2013). In addition, agricultural policy should also harmonize the relationship among actors in the supply chain and encourage the agribusiness to develop more sustainable, added value products through trade governance.…”

Study on Total Factor Productivity of Chinese Tea Industry and Regional Disparity based on DEA-Malmquist Model

“…The change of TFP can be divided into technical progress, technical efficiency, allocative efficiency and economic efficiency of scale [9]. There are also many literatures about the TFP , technical efficiency and technical efficiency amd their deterninants [10], technical efficiency and agriculture policy [11]. Besides, chemical components and pesticide have been widely used by tea farmers for protecting tea farms.…”

“…In 1953, Malmquist put forward the Malmquist index for the first time, and then Caves and others used the Malmquist index to measure productivity. Fare and others further put forward that a distance function was used to describe production technology of multiple input variables and multiple output variables [18]. Using the directional output method or directional input method to define the distance function and giving the input variable matrix, an output distance function is defined as the optimal s.t.…”

Do outsourcing services provided by agricultural cooperatives affect technical efficiency? Insights from tobacco farmers in China

“…Additionally, there has been extensive literature on agricultural technical efficiency. However, these studies mainly focus on the relationship between technical efficiency and farmers’ participation in cooperatives (Lin et al., 2022, Ma et al., 2018, Kumar et al., 2018), e‐commerce adoption (Chen et al., 2022), environmental services (Rodríguez et al., 2022), machinery‐sharing arrangements (Larsén, 2010), technology adoption (Qiao and Huang, 2020), agricultural training (Nguyen‐Van and To‐The, 2016) and off‐farm employment (Yang et al., 2015). Others study the relationship between technical efficiency and land fragmentation (Tan, 2005) or technical efficiency and land transfers (Deininger et al., 2013, Ma et al., 2017b, Jin and Jayne, 2013).…”
