Analysis of the animal feed to poultry value chain in Zambia

ABSTRACT

Rapidly growing populations, urbanisation and income are together triggering increased demand for high-value agricultural commodities across Southern Africa with scope for gains from trade and regional integration. The poultry sector in Zambia, in particular, has witnessed a rapid growth triggering increased investments and competition, benefiting the consumers. Despite this growth, the sector still faces huge challenges hindering the development of the animal feed, feed input and poultry production sub-sectors. This has limited the extent of participation of the Zambian poultry industry in the regional market due to uncompetitive prices. This study analyses the animal feed to poultry value chain in Zambia, focusing on the industry capabilities with a view to enhancing its competitiveness and production for the regional market. Enhancing value chain capabilities will require improvements in productivity and production of key poultry inputs, and addressing transportation inefficiencies and coordination among governments.     

Firm heterogeneity,credit constraints,and endogenous growth

This paper is in general concerned with the role of firm heterogeneity for economic growth. We focus on heterogeneous productivity in innovation and credit constraints of firms within a semi-endogenous growth model reflecting recent empirical findings on firm heterogeneity. Our model allows for an explicit solution for transitional growth and for the balanced growth path level of innovations or ideas. The model predicts an optimal degree of heterogeneity in the presence of an endogenous firm distribution. This enables us to draw inference about the impact of key policy parameters of the model on these quantities and to draw conclusions about firm and capital market related policies.     

Africa's changing farm size distribution patterns: the rise of medium‐scale farms

This study assesses changes over the past decade in the farm size distributions of Ghana, Kenya, Tanzania, and Zambia, drawing on two or more waves of nationally representative population‐based and/or area‐based surveys. Analysis indicates that much of Sub‐Saharan Africa is experiencing major changes in farm land ownership patterns. Among all farms below 100 hectares in size, the share of land on small‐scale holdings under five hectares has declined except in Kenya. Medium‐scale farms (defined here as farm holdings between 5 and 100 hectares) account for a rising share of total farmland, especially in the 10–100 hectare range where the number of these farms is growing especially rapidly. Medium‐scale farms control roughly 20% of total farmland in Kenya, 32% in Ghana, 39% in Tanzania, and over 50% in Zambia. The numbers of such farms are also growing very rapidly, except in Kenya. We also conducted detailed life history surveys of medium‐scale farmers in each of these four countries and found that the rapid rise of medium‐scale holdings in most cases reflects increased interest in land by urban‐based professionals or influential rural people. About half of these farmers obtained their land later in life, financed by nonfarm income. The rise of medium‐scale farms is affecting the region in diverse ways that are difficult to generalize. Many such farms are a source of dynamism, technical change, and commercialization of African agriculture. However, medium‐scale land acquisitions may exacerbate land scarcity in rural areas and constrain the rate of growth in the number of small‐scale farm holdings. Medium‐scale farmers tend to dominate farm lobby groups and influence agricultural policies and public expenditures to agriculture in their favor. Nationally representative Demographic and Health Survey (DHS) data from six countries (Ghana, Kenya, Malawi, Rwanda, Tanzania, and Zambia) show that urban households own 5–35% of total agricultural land and that this share is rising in all countries where DHS surveys were repeated. This suggests a new and hitherto unrecognized channel by which medium‐scale farmers may be altering the strength and location of agricultural growth and employment multipliers between rural and urban areas. Given current trends, medium‐scale farms are likely to soon become the dominant scale of farming in many African countries.     

Strategic Suppliers' Technical Contributions to New Product Advantage: Substitution and Configuration Options

Current theory lacks clarity on how different kinds of resources contribute to new product advantage, or how firms can combine different resources to achieve a new product advantage. While several studies have identified different firm‐specific resources that influence new product advantage, comparatively little research has explored the contribution of strategic supplier resources. Combining resource‐based and relational perspectives, this study develops a theoretical model investigating how a strategic supplier's technical capabilities impact focal firm new product advantage and how firms combine different resources to gain this advantage. The model is tested using detailed survey data collected from 153 interorganizational new product development projects in the United Kingdom within which a strategic supplier had been extensively involved. Empirical results support our research hypotheses. First, supplier technical performance is shown to have a significant positive impact on new product advantage. Next, we show that while supplier technical capabilities have a positive influence on supplier technical performance, the a priori nature of the supplier's task moderates the relationship. Finally, our data support our hypotheses related to the positive relationship between relationship‐specific absorptive capacity and new product advantage, and the proposed negative moderation of supplier technical capabilities on this relationship. Based upon these findings, we encourage managers to recognize that strategic suppliers' with greater technical capabilities perform better regardless of the degree of creativity required by their task; but that strategic suppliers with lower technical capabilities may partially compensate (substitute) for their lack of technical capabilities, if they are able to respond to high problem‐solving task requirements. Furthermore, we suggest that the firm's development of relationship‐specific absorptive capacity is much more important when a strategic supplier is less technically capable. A buying firm's relationship‐specific absorptive capacity can, according to our data, substitute for low supplier technical capabilities. On the other hand, where the supplier has strong technical capabilities, investments in relationship‐specific absorptive capacity have no effect on new product advantage. Our findings reinforce recent calls for research on how firms can combine different resources and capabilities to achieve superior performance.     

The Multinational Corporation and Global Governance: Modelling Global Public Policy Networks

Globalization has increased the economic power of the multinational corporation (MNC), engendering calls for greater corporate social responsibility (CSR) from these companies. However, the current mechanisms of global governance are inadequate to codify and enforce recognized CSR standards. One method by which companies can impact positively on global governance is through the mechanism of Global Public Policy Networks (GPPN). These networks build on the individual strength of MNCs, domestic governments, and non-governmental organizations to create expected standards of behaviour in such areas as labour rights, environmental standards, and working conditions. This article models GPPN in the issue area of CSR. The potential benefits of GPPN include better overall coordination among industry and government in establishing what social expectations the modern MNC will be expected to fill.

Linking learning and knowledge creation to project success in Six Sigma projects: An empirical investigation

This study investigates the impact of two organizational antecedents, (1) Six Sigma resources (technical) and (2) team psychological safety (social), on learning behaviour and knowledge creation and, in turn, on the success of Six Sigma process improvement projects. The paper proposes an integrated model to explain process improvement implementation success through two learning activities undertaken by Six Sigma project teams: Knowing-what and Knowing-how. The conceptualization of these knowledge types in this research is different from usual conceptualization as it represents the knowledge brought into projects through various phases of Six Sigma projects. The three hypotheses proposed in the model were tested using the data collected from 52 Six Sigma project teams from a single organization. Regression analysis showed psychological safety affects project performance through knowing-how. Regression and bootstrapping analyses showed resources influence project performance through the combined mediation of knowing-what and knowing-how.The paper provides an interdisciplinary treatment of knowledge management in process improvement teams, and offers a research model demonstrating how Six Sigma project teams promote deliberate organizational learning. By doing so, this study empirically establishes the notion that technical and social supports jointly impact the success of operations management initiatives such as Six Sigma through learning. The limitations of the study along with the future research directions are highlighted.
