Factors influencing consumers' choice of imported poultry meat products in a developing market : lessons from ZimbabweSource: Agrekon 55, pp 191 –215 (2016) http://dx.doi.org/http://dx.doi.org/10.1080/03031853.2016.1203800More Less
The main objective of this study was to explore factors that influence consumers' choice of imported poultry meat products in Zimbabwe, a developing market. Quantitative and qualitative methods were used to analyse data collected from a sample of 305 consumers. The study found that factors that influence consumers' choice of imported poultry meat products are price, health and safety issues, accessibility, appearance, taste, tenderness, genetically-modified food status, product labelling, country of origin, packaging, production methods and branding. These factors are classified into three overlapping categories, namely economic factors, quality and product attributes, and the firm's marketing efforts. Economic factors include price in relation to consumer disposable income. Quality and product attributes include health and safety issues, appearance, taste, tenderness, genetically-modified food status, packaging, country of origin and production methods. The firm's marketing efforts include price, accessibility, product labelling, packaging and branding. These findings have implications for theory and practice.

Data limitations lead to the use of assumptions that compromise studies on the measurement of capital in the national accounts and its impact on productivity analysis in South Africa. In the estimation of physical capital such as machinery and implements, a possible approach is to use the ratio of the value of tractor sales to overall expenditure to impute overall machinery sales. The use of a constant ratio over an extended period results in increasingly incorrect estimates and fails to reveal the changing nature of mechanisation. In this article, the problems with such an approach are highlighted through an analysis of the historic share of tractor sales to overall machinery sales in South Africa. This article establishes that the current methods have led to underestimation in the overall value of machinery and implements sales in South Africa by approximately a billion rand per annum for recent years. An alternative method is suggested and the implications of a new capital formation series are discussed.
Estimating the supply response of maize in South Africa : a Nerlovian partial adjustment model approachSource: Agrekon 55, pp 237 –253 (2016) http://dx.doi.org/http://dx.doi.org/10.1080/03031853.2016.1203802More Less
Maize is the most important crop in South Africa, being both the major feed grain for livestock and the primary staple food crop for the majority of the population. Farmers' production decisions regarding maize and their response to policy incentives are critical for national food security and regional trade. The aim of the study was to estimate the supply response of the South African maize sector to price and non-price incentives. A Nerlovian partial adjustment model was applied to historical time series data of area under maize cultivation, measured in hectares spanning from 1980-2012 to determine the supply response. Results indicate a short-run price elasticity of 0.24 and a long-run price elasticity of 0.36, signifying that maize farmers are less sensitive to price changes than non-price incentives. The results confirm that non-price incentives such as rainfall and technology seem to have more effect on maize supply than price incentives in South Africa. Given the findings, the study recommends policies and programmes that focus more on non-price incentives, such as technology and infrastructure development, investment in irrigation and research services, as a means of stabilising maize production in South Africa.
The choice of marketing channel by maize and pigeonpea smallholder farmers : evidence from the northern and eastern zones of TanzaniaSource: Agrekon 55, pp 254 –277 (2016) http://dx.doi.org/http://dx.doi.org/10.1080/03031853.2016.1203803More Less
This study examines the factors affecting the choice of marketing channel used by smallholder maize and pigeonpea farmers in the northern and eastern zones of Tanzania. The reason for the focus on maize and pigeonpea is because these products are key crops that contribute to household production, consumption and cash income in the study zones. A Multinomial Logit Analysis of a multistage sample of 562 smallholder farmers, who market maize and pigeonpea, showed that transaction costs, household wealth, access to credit and extension services, and social capital affect their choice of marketing channel. This outcome suggests that policies aimed at reducing transaction costs, improving access to productive assets, prudent use of credit, and promoting the use of well-organised farmer groups to access appropriate technology and information could enhance market access and better integrate smallholder farmers into markets in the study areas.

Food security is recognised as a multifaceted condition of complex causality, and given its broad definition, it is no surprise that food security eludes precise measurement. This study considers there to be three components of household food security (quantity, quality and stability), and attempts to address the "concept-to-measurement" gap in food security by building an index that spans these three dimensions. A panel data set from rural Zambia is used for descriptive analysis of food security indicators in 2001, 2004 and 2008. A multidimensional index of food security for rural Zambia is then developed using principal component analysis. We use this index to explore the spatial patterns of food security over time and to assess correlates of food security and impacts of climate shocks. Results indicate that both rainfall and temperature have a significant impact on a household's food security score, though not for each individual component of the index. The paper concludes with a discussion of the merits and shortcomings of developing a composite food security index.
