70 percent of the world and 80 percent of China’s tea production produced by smallholder farmers. However, the tea production per unit area significantly unchanged in the past decades. Understanding factors affecting the technical efficiency of smallholder tea producers is very important to maximize tea production. Aimed at examining the impact of land tenure security and land certification on smallholder tea producers’ technical efficiency, this paper employs the Cobb- Douglas Stochastic Production Frontier (CD-SPF) and Translog Stochastic Production Frontier (TL- SPF) methods for Maximum Likelihood Estimate (MLE) with cross-sectional data collected from 161 randomly selected tea farm plot households in Ya’an city, China. We found that an 1 mu (0.067 ha) increase in the tea farm size will produce a 1.086 tea yield advantage for smallholder tea farmers. We also found that the values of input-output elasticity of land size, household income and labor decrease in turn with 0.144, 0.105 and 0.010 respectively. The results show that farm size is a more crucial input for tea production than income and labor. Moreover, we identify the determinations which enhance the technical efficiency of smallholder tea producers such as land certification, land tenure security age, education, farming experience, total farm size holding, chemical fertilizer, plot steepness and plot distance from home and find that the elimination of land tenure insecurity through land registration and certification makes a clear difference in that. We therefore recommend that tea farmland need to expand and enlarge for better production through comprehensive land consolidation program. We also suggest endorsing the land certificates of all land holders as this will help improve land tenure security, enhance technical efficiency and promote the tea production of smallholder producers.

Stochastic Production

Agricultural productivity in Africa is the lowest in the world with many households not being able to feed themselves. In Africa, women play a major role in agriculture sector constituting about 70–80 per cent of the labour force there. Regrettably, their farm productivity is relatively low mainly due to their inefficient use of farm inputs, which has a serious implication for their socio-economic condition as well as health and nutrition status. With this backdrop in mind, the study investigated the technical efficiency (TE) of the female crop farmers in Niger Delta, Nigeria. Stochastic production frontier approach and ANOVA models were applied to analyse the primary data collected on the 216 female farmers randomly selected from 18 communities of the 3 states in the Delta. It has been found that the farm size and the quantity of labour positively influence TE of these farmers. However, farmer’s age shows a negative sign implying a decrease in technical inefficiency in age whereas the years of schooling shows a positive sign implying an increase in inefficiency with schooling thereby a resulting decrease in TE with schooling. Farm efficiency level in Delta and Akwa Ibom States was not significantly different. However, TE level in both Delta and Akwa Ibom States was significantly different from Rivers State. Since, the age of farmers showed positive influence on TE, farmers should form group and organise regular meetings to enable share knowledge and experiences on the efficient use of farm resources in the Niger Delta Region, Nigeria.

The Impact

Background: To address the structural food deficit and top down extension system that persisted for decades, the government of Ethiopia has introduced a new extension system, called Participatory Demonstration and Training Extension Systems, which serves more than 80% of the total population. As the program was streamlined to fit the different agro-climatic condition of the country, the extension approach practiced in the Tigray region (research area) was called Integrated Household Extension Program.Aim: This article reports on research aimed at measuring the technical efficiency levels of extension participants and non-participants; measuring the impact extension service on technical efficiency.Setting: The research was conducted in the northern part of the country, where agriculture is the main sources of livelihoods. Moisture is the most critical factor in the production system. The land holding size averages 0.5 ha per household compared to above three ha 30 years ago; indicating the high population pressure in the area.Methods: A sample of 362 agricultural extension service participants and 369 non-participant farm households from the northern part of Ethiopia, participated in the study. The stochastic production frontier technique was used to analyse the survey data and to compute farm-level technical efficiency.Results: The results showed an average level of technical efficiency of 48%. It is suggested that substantial gains in output and/or decrease in cost can be attained with the existing technology. All the variables included in the model to explain efficiency were found significant and with the expected sign, except education and number of dependants.Conclusion: The research tried to assess the impact of a new extension service (participatory in nature) on farmers’ productivity in a semi-arid zone, as compared with the conventional extension service and found in the literature areas with relatively better climatic conditions. Hence, if extension administrators could work to uplift the average and below average farmers into better performing farmers level, the overall production and living condition could improve substantially in the research area, and more or less in the rest part of the country.

The Impact

In Finland, expanding dairy farms often face the problem of additional fields being geographically distant and only available as small parcels. We develop a stochastic production frontier model to estimate the technical efficiency of Finnish dairy farms and simulate the effect of parcel distance and parcel size on the efficiency of an average farm for 2000 through 2009. The overall development of technical efficiency is positive during the study period but increases in distance and decreases in parcel size both significantly reduce farm efficiency. Therefore, efforts to improve the parcel structure are justified.

In this paper, we identify the effect of rural extension on the productive performance of Brazilian agricultural establishments, using technical efficiency as a measure of farm performance. The data used is drawn from the microdata of the 2006 Agricultural Census, accessed directly from the IBGE secrecy room. For this, we use an approach that combines the stochastic production frontier, considering selection bias in the adoption of rural extension (Heckman’s approach) and entropy balancing. We find that rural extension increases efficiency in the use of the productive inputs, with more technical efficiency found among adopting producers than non-adopters. When considering the differences according to farm size, an even greater effect is observed for larger producers. In addition, public rural extension generates higher technical efficiency scores than those obtained by privately-operated establishments.

AbstractHaving data sample in 1987, 1995, and 2008, this research aims to analyze the impact of trade liberalization on technical efficiency of Indonesian manufacturing firms since deregulation in the 1980s. In addition, the research also analyzes the impact of other efficiency determinants coming from firm characteristics and market structure. Technical inefficiency score is estimated by using stochastic production frontier model, whereas the impact of efficiency determinants is analyzed by using Ordinary Least Squared model (OLS). For each year observed, liberalization has different impacts on technical efficiency. However, as liberalization continues, it has facilitated firms to produce towards their full technical efficient production-level.Keywords: Trade Liberalization, Firm Technical Efficiency, Manufacturing Industry, IndonesiaAbstrakDengan mengambil sampel tahun 1987, 1995, dan 2008, studi ini dilakukan untuk menganalisis dampak liberalisasi perdagangan terhadap efisiensi teknis perusahaan dalam industri manufaktur Indonesia sejak deregulasi pada tahun 1980-an. Selain itu, dianalisis pula pengaruh faktor determinan efisiensi lainnya yang berasal dari karakteristik internal perusahaan dan struktur industri. Nilai inefisiensi teknis diestimasi dengan model stochastic production frontier, sedangkan analisis pengaruh faktor determinan efisiensi teknis menggunakan model Ordinary Least Squared (OLS). Hasil studi menunjukkan bahwa liberalisasi perdagangan memiliki dampak berbeda terhadap efisiensi teknis pada setiap tahun yang diamati. Namun, liberalisasi akhirnya dapat memfasilitasi perusahaan dalam meningkatkan performanya, melalui peningkatan nilai efisiensi teknis.Kata kunci: Liberalisasi Perdagangan, Efisiensi Teknis Perusahaan, Industri Manufaktur, Indonesia
