Estimating technical, allocative and cost efficiencies and their socioeconomic drivers: A case of selected small-scale growers in Northern KwaZulu-Natal, South Africa
No full textSouth African small-scale sugarcane growers are faced with high production costs that have an impact on agricultural efficiency and their ability to adopt newly available technologies for production purposes. This study employed the Data Envelope Analysis (DEA) approach and Truncated regression model to analyse data collected from 160 growers. The findings reported technical, cost and allocative mean scores to be 95.6,% 55.2%, and 57.5% in the Felixton region whereas 95.2%, 69.1% and 72.6% were achieved in the Amatikulu area, respectively. The age, extension support, and off-farm income had a negative effect on agricultural efficiency followed by positive effect of experience, education, access to credit and employment that showed positive relationship. We propose government to work jointly with mill owners to train, develop extension officers and subsidise inputs and equipment to address the poor allocation of resources because of financial constraints currently faced by small-scale sugarcane growers
Estimating efficiency levels and their determinants among small-scale sugarcane growers in northern KwaZulu-Natal, South Africa
Get PDFSouth African small-scale sugarcane growers are faced with high production costs that may lead to agricultural inefficiency because of an inability to adopt newly available production technologies.

Impact analysis of the linkage between agricultural exports and agriculture’s share of Gross Domestic Product in South Africa : a case of Avocado, Apple, Mango and Orange from 1994 to 2011
Get PDFThesis (MA. Agricultural Management (Agricultural
Economics)) -- University of Limpopo, 2014The role of agricultural exports to agriculture’s share of Gross Domestic Product (GDP) in South Africa is of extreme importance and exhibits strong interest from all parts of the economy. Many believe that agriculture can salvage the declining economic growth under such global economic conditions. The decision to diversify and expand exports of these avocados, apples, mangoes and oranges will improve the South African economy’s unstable conditions. This study accounts for all the factors that are truly unique to South African’s economy. Therefore, the study will help to shift the focus of avocado, apple, mango and orange growers to export more due to the international market demand for such produce.
The aim of the study was to analyse the link between avocado, apple, mango and orange exports and agriculture’s share of Gross Domestic Product in South Africa. The specific objectives are to determine the correlation between avocado, apple, mango and orange exports and the agriculture’s share of Gross Domestic Product in South Africa, investigate the contribution of avocado, apple, mango and orange exports and the agriculture’s share of Gross Domestic Product in South Africa, determine the growth rate (trends) of avocado, apple, mango and orange exports and determine the volatility of avocado, apple, mango and orange exports. The study used secondary time series data that covered a sample size of 17 years (1994 - 2011) of avocado, apple, mango and orange exports in South Africa. Two Stages Least Square models and Growth rate and Volatility models were used for data analysis.

Empirical results for agricultural exports equation revealed that agricultural economic growth in South Africa was significant with a positive coefficient. While a negative relationship between the Net Factor Income (NFI) and the agricultural exports in South Africa was noticed. Real Capital Investments had a significant positive coefficient. Consequently, results from agricultural economic growth equation revealed that agricultural exports were significant with a positive correlation. A relationship between NFI and agricultural GDP was also witnessed. Like other variables, Real Capital Investment was significant but negatively correlated. The results of growth rate and volatility models showed positive trends. Furthermore, results showed that the quantity of agricultural exports was positively related to agricultural economic growth. Another point of interest was that while these exports were positive and significantly related, the magnitude of its coefficient is smaller than the coefficients of Real Capital Investments. It is in this framework that the positive correlation exists between agriculture economic growth and agricultural exports.
It is recommended that investment opportunities in the agricultural sector need to be investigated further because there is limited knowledge of the subject. The Department of Agriculture, Forestry and Fishery and the private sector need to join hands and build a mutual relationship to aid develop an agricultural economy which can be able to exports more than what it imports. This can also be done by subsidising farmers with capital to relieve them of other expenses
Efficiencies of small-scale sugarcane growers in the King Cetshwayo District Municipality of KwaZulu-Natal
Get PDFA thesis submitted for the Degree of Doctor of Commerce in the Department of Economics, Faculty of Commerce, Administration and Law at the University of Zululand, 2019.Low agricultural productivity remains a threat to the existence and sustainability of the small-scale production of crops. Unfavourable climatic conditions such as drought are a concern to the long-term supply of food in the context of a rapidly growing population. The continuous uncertainty surrounding access to credit, extension support and industry regulations exacerbate the dilemma faced by small-scale growers. Therefore, there is a need to develop strategies to promote agricultural efficiency and productivity.
Sugarcane is a traditional crop produced in three provinces in South Africa and it contributes to the livelihoods of many small-scale sugarcane growers operating in the rural set-up. This thesis aimed to evaluate agricultural efficiencies, productivity and efficiency change and identify barriers to technical efficiency of small-scale sugarcane growers in the sugar producing regions of the King Cetshwayo district municipality. This is a grey area as existing studies have given more attention to SFA (Stochastic Frontier Analysis) and ranked constraints faced by small-scale sugarcane growers. The thesis analyses three methodological approaches to addressing the objectives of the thesis. The first objective was to analyse the technical, cost and allocative efficiency of a sample of 300 small cane growers located in the King Cetshwayo district municipality (KCDM) of Northern KwaZulu-Natal. This objective was achieved through estimating agricultural productive efficiency using Data Envelope Analysis (DEA). The second objective was to determine the chemical-input use efficiency, which was determined using the Slack-Based Measure (SBM) approach of the sampled cane growers. The third objective was to employ the Truncated Regression model to identify key socio-economic sources of technical efficiency; this chapter relied on field survey data of 300 sugarcane growers.
The fourth objective measured input-oriented technical, cost and allocative efficiency of 160 small-scale sugarcane growers in the Felixton and Amatikulu regions. The fifth objective investigate the determinants of technical, cost and allocative efficiency in the Felixton and Amatikulu regions. Both objectives used the DEA and Truncated Regression model. The sixth objective decomposed agricultural efficiency change in small-scale sugarcane growers in the Amatikulu region using the Färe Primont Index (FPI) using farm-level data for 38 small-scale growers. Furthermore, the Bayesian Modelling Average technique (BMA) investigated policy-related sources of small-scal
The Socioeconomic determinants of foreign capital inflows in selected Sub-Saharan African Countries
Get PDFForeign capital inflows (FCI) are essential for economic growth in developing countries. This study examines the socioeconomic factors affecting FCI in 31 Sub-Saharan African (SSA) countries, utilizing panel data from 1985 to 2019 and employing the System GMM dynamic modeling approach. The findings indicate that when foreign direct investment (FDI) is treated as an endogenous variable, real interest rate (RIR), life expectancy (LEX), GDP growth rate, and food security (foodsec) have significant positive impacts. Conversely, the real exchange rate (RER) and inflation (INF) negatively correlate with FDI. Human capital investment is not statistically significant while the relationship between lagged FDI and current FDI is positive but nonsignificant. When foreign portfolio investment (FPI) is considered an endogenous variable, only food security exhibits a positive and statistically significant factor, suggesting that food security can enhance FPI flows. The study recommends that SSA countries aiming to attract more FCI should focus on improving healthcare, food security, and education. It is also suggested that countries should develop highly skilled R&D employees, public and private scientific research institutions, and industrial concentration in a country because they fundamentally drive the development and success of foreign capital flow levels. Central banks should also implement effective strategies to optimize capital flows by advancing financial institutions
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
