The purpose of this paper is to evaluate consumers’ willingness to pay (WTP) for composite flour bread produced with a blend of 15-40 per cent cassava flour blended with wheat flour in Ghana.

The analysis is based on interviews with 350 consumers in the Ashanti and Eastern Regions of Ghana to assess their awareness, perceptions and WTP for cassava-wheat composite bread. From these consumer interviews, a hedonic regression model was applied to evaluate consumers’ WTP for various attributes of composite flour bread. Price-related and health-related perceptions of consumers on cassava-wheat composite bread were investigated with perception indices. Multi-attribute preference-based contingent ratings that rate product attributes in terms of importance to consumers was employed. The implicit prices of the product attributes representing the contribution of the product attributes to the WTP amount were also computed.

The paper finds that consumers who are aware of cassava-blended flour bread and who like its taste and texture are willing to pay more than consumers who are unaware. This leads to a policy recommendation advocating increased advertising of the economic and nutritional benefits of cassava-wheat blended composite flour bread.

Future studies should explore the choice experiments to examine preferences for the food product.

This paper evaluates consumers’ WTP for composite flour bread produced with a blend of 15-40 per cent cassava flour and wheat flour. Given widespread reliance on imported wheat flour and the simultaneously large volumes of locally available cassava, it is important to consider opportunities for import substitution (and possible cost reduction for consumers) of blended flour products such as cassava-wheat composite flours. Nigeria has imposed a 10 per cent blending requirement for this reason. Ghana has taken important measures recently for the development of high-quality cassava flour, and so research on its potential and actual uptake is welcomed and highly relevant to food security and agribusiness development.

The purpose of this paper is to examine the effect of corruption and shadow economy on public debt in 51 African countries. In addition, the study explores the causal linkage between corruption, shadow economy and public debt.

The study employs vector error correction model and Kao cointegration test to examine the long-run relationship between corruption, shadow economy and public debt in Africa.

The study finds a positive and statistically significant relationship between corruption and public debt. Further, the study reports a positive and statistically significant effect of shadow economy on public debt. In the short run, the study finds a unidirectional causal relationship between corruption, shadow economy and public debt with the direction of causality running from corruption and shadow economy to public debt, respectively.

This study recommends that countries should pursue policies and programs that would provide resources to agencies tasked with the responsibility of fighting corruption. This would ensure that countries have effective institutions that curb vulnerabilities to corruption and reduce the size of the shadow economy and public debt.

This study contributes to the literature by showing how corruption and shadow economy affects public debts of African countries. To the best of the author's knowledge, this is the first attempt to examine this relationship in the context of Africa.

The nexus between sustainable agri-food production and food security outcomes of farm households in sub-Saharan Africa is attracting policy attention. This study analyzes the effects of crop diversity on the incidence of food scarcity, dietary diversity, and the sale and consumption of own crops.

The study uses panel data collected in 2015 and 2018 on a randomly selected sample of 2553 households from 49 villages in northern Ghana. The study employed a fixed effects modeling approach in the empirical analysis.

The study finds that crop diversity is positively associated with better dietary diversity, reduced hunger, lower food expenditure, and higher consumption of own produce. The results show positive effects of crop diversity on the total harvested output and sale of agricultural production. Whilst sales improved sustainable food and nutrition security by providing purchasing power to buy nutritional inputs in the market, consumption of own produce rather improved food availability by reducing food scarcity and malnutrition.

Crop diversity is one of the pathways for promoting sustainable agri-food production systems to ensure the food and nutritional security of vulnerable populations and promote biodiversity to achieve environmental goals in sub-Saharan Africa. Crop diversity reduces food expenditure and raises rural incomes through improved outputs and sales, which empowers farm households to diversify their dietary options to be able to overcome incidences of hunger and malnutrition in periods of food scarcity.

The present study improves the understanding of sustainable agri-food production through crop diversity and its implications on food and nutrition security outcomes. The panel data and fixed effects modelling approach address the endogeneity problem between crop diversity and household tastes and preferences.

Research efforts aiming to improve understanding of how various organisational relationships contribute to better food quality (FQ) in a constantly changing business environment are limited. This study examines the effects of supply chain (SC) organisations on the quality of food products across multi-tiered segments with dynamic business situations.

Guided by a conceptual research framework based on contingency theory and netchain analysis, moderation-based partial least squares structural equation modelling (PLS-SEM) was used to analyse multi-tiered data from 405 shrimpers and 238 women processors in Akwa-Ibom, Lagos and Ondo states in Nigeria.

The authors' findings show that unpredictable business environments such as market turbulence (MT), power asymmetry (PA) and distrust (DT) not only directly influence SC organisations but also moderate how organisational networks contribute to improved FQ. Further results reveal that closer vertical ties such as relational contracts are prerequisites for small-scale actors to guarantee improved FQ along multiple nodes of the food system.

This is the first study to examine, from a contingency and multi-tiered perspective, how small-scale actors can maintain FQ across interdependent nodes of a food chain in a developing country context and to explore the complex interplay between SC networks and the quality of highly perishable food products in unpredictable business environments. Relevant theoretical and policy implications are discussed.

This article analyzes farmers' preferences for different nonindexed crop insurance alternatives, using discrete choice experiment data on cocoa farmers from southern Ghana. We examine farmers' attendance to attributes by comparing self-reported attribute nonattendance (ANA) to the behavior inferred from the choices.

We utilize the latent class endogenous attribute attendance (EAA) model to address potential endogeneity by jointly modelling farmers' attribute processing strategies with their choice of attributes of the insurance products.

The results show that premium levels, mode and length of indemnity payouts tend to influence farmers' preferences for crop insurance products. The findings also reveal that credit-constrained farmers attend more to premium and payment mode attributes of the crop insurance products and that credit-constrained farmers tend to exhibit lower willingness-to-pay estimates for the crop insurance attributes.

The findings from the study suggest that credit constraints do not only limit input use, but also tend to have statistically significant impact on farmers' cocoa insurance participation decisions.

The study examines the impact of credit constraints on farmers' crop insurance preferences while accounting for ANA.

The purpose of this paper is to investigate the effect of institutional quality on foreign direct investment (FDI) flows in South America.

The study uses two-stage least squares (2SLS) and fixed effect ordinary least squares regression analyses to examine the relationship between institutional quality and FDI in South America.

The study finds a significant positive relationship between institutional quality index and FDI. This implies that improvements in the institutional quality relate to increases in the flow of FDI to South America. Domestic capital, GDP per capita growth, and trade positively relate to FDI. However, the coefficient of trade is not significant. This implies that increases in these variables relate to increases in FDI flows to South America.

The study recommends that quality of institutions matter to the flow of FDI and therefore, efficient institutional reforms should be a priority for policymakers as this creates a conducive investment environment to attract FDI in South America. Further, policies that are focused on promoting competition, open market, and effective non-corrupt public institution as well as open and transparent legal and regulatory regimes, and effective delivery of government services should be the priority of policymakers in South America (Mishra and Daly, 2007).

The study uses a single measure of institutional quality based on a broad set of institutional indicators. This broad measure of institutional quality differs from the available studies that mainly focused on single aspects of institutional quality, that is, either corruption, governance, or political risk.

The purpose of this paper is to investigate the impact of foreign direct investment (FDI) on economic growth in countries in South America. Additionally, the study explores the causal linkage between FDI and growth in the region.

The study employs Pedroni’s cointegration test to examine the long-run relationship between FDI and economic growth in South America. Further, the study employs the vector error correction model (VECM) to examine the long-run relationship, and the causal nexus between FDI and economic growth in South America for the period 1980–2015.

The Pedroni cointegration test establishes a long-run relationship between FDI and economic growth in a panel of ten countries in South America. The long-run estimates of the study find a significant positive impact of FDI on economic growth in the region. The VECM results find a short-run bidirectional causality between FDI and economic growth. The error-term is negative and significant. This indicates the presence of long-run equilibrium relationship among the variables.

Countries in South America should adopt policies that would substantially enlarge FDI inflows to enhance their growth and development.

Numerous studies have examined the impact of FDI on economic growth in the context of Latin America. This study fills a gap in the existing literature by providing an empirical evidence that focuses on South America. This additional perspective could form the basis for the evaluation of the investment policies, and help policymakers to pursue FDI policies that would enhance growth and development in South America.

The purpose of this paper was to assess the economic impact of investment in different animal welfare–enhancing flooring solutions in Swedish dairy farming.

The authors developed a bio-economic model and used stochastic partial budgeting approach to simulate the economic consequences of enhancing solid and slatted concrete floors with soft rubber covering.

The findings highlight that keeping herds on solid and slatted concrete floor surfaces with soft rubber coverings is a profitable solution, compared with keeping herds on solid and slatted concrete floors without a soft covering. The profit per cow when kept on a solid concrete floor with soft rubber covering increased by 13%–16% depending on the breed.

Promoting farm investments such as improvement in flooring solution, which have both economic and animal welfare incentives, is a potential way of promoting sustainable dairy production. Farmers may make investments in improved floors, resulting in enhanced animal welfare and economic outcomes necessary for sustaining dairy production.

This literature review indicated that the economic impact of investment in specific types of floor improvement solutions, investment costs and financial outcomes have received little attention. This study provides insights needed for a more informed decision-making process when selecting optimal flooring solutions for new and renovated barns that improve both animal welfare and ease the burden on farmers and public financial support.

The purpose of this work is to study the relationships of trust in a local agri-food supply chain in Southern Brazil. In an unsustainable context, where the number of mariculturists is decreasing, the authors seek to identify what the factors are and how they contribute to this problem, as well as find solutions aimed at the sustainability of that chain.

The authors carried out qualitative research with 15 semi-structured interviews that took place in the year 2021. The thematic analysis of the results applied the IRAMUTEQ software and the assessment of the narratives was guided by prior thematic analysis.

The supply chain under investigation requires better organisation. Communication and interpersonal trust proved important in the relationship between producers and control bodies. The university, as a seed supplier, needs predictability and efficiency to convey inter-organisational trust. Informal relationships are interpersonal and extremely trust-based and inter-organisational trust increases the performance of establishments and promotes the development of innovative structures. Furthermore, in crisis periods interpersonal trust increases.

The results allow policymakers to plan better their actions and build more effective tactics in order to reach sustainable development. This work is also important for stakeholders and managers, as it guides improvements in management, governance and sustainability of agri-food supply chains.

An unprecedented research was done on the studied supply chain, knowing the relationships of trust among them, identifying peculiar partnerships and recognising some constructs and outcomes of trust.

This paper aims to explore the evolutionary dynamics of innovation ecosystems in the food industry by adopting both open innovation and convergence approaches to derive practical policy implications to develop impactful innovation ecosystems to promote food production sustainably.

Starting from the cutting-edge case of Foodvalley in the Netherlands, the study adopts a backcasting approach to reach a future vision of food ecosystems from a sustainable food production perspective. The authors set the backcasting analysis in four steps: (1) description of the present and trends analysis, (2) selection of trustworthy criteria and goals, (3) development of future images and (4) analysis of how to reach the images.

The trends analysis has identified three existing innovation fields – protein shift, circular agrifood and food and health – and two strategic directions – convergence and localness decrease. The study reports how a long-term commitment may lead the valley toward a best future scenario.

The study suggests that policymakers and stakeholders can promote innovation strategies in sustainable food production ecosystems by encouraging collaboration between different sectors, reducing regulatory barriers, attracting innovative actors, and investing in education and training programs. To achieve measurable environmental and social impact outcomes, policies should promote entrepreneurship and create an enabling environment that encourages innovation and risk-taking.

The originality of this paper concerns the backcasting perspective applied to the analysis of the food ecosystem. This approach facilitates the identification of a path direction for successfully managing open innovation and industry convergence toward a desirable future of sustainable food production.
