This paper examines the impact of regional and non-regional trade on economic growth using annual data from Economic Community of West African States (ECOWAS) member countries for the period 2007 to 2017.

Trade data were decomposed into regional (trade among ECOWAS Member States) and non-regional (trade between ECOWAS Member States and the rest of the world). We used the dynamic system GMM to estimate the models and introduced exchange rate, unemployment rate, population growth and gross capital formation as controlled variables.

The results revealed that the estimated coefficient of ECOWAS regional trade is statistically significant and positive in predicting growth, while the non-regional trade coefficient is negative and not statistically significant in predicting growth. Other predictors of growth introduced into the model as controlled variables, such as exchange rate, unemployment rate, population growth and gross capital formation, displayed mixed results. More importantly, population growth, unemployment and exchange rate depreciation hurt economic growth, while gross capital formation promotes economic growth.

The findings provide strong support in favour of the Krugman (1991) hypothesis that regional trade agreements (RTAs) are a better alternative to global trade.

Our decision to disaggregate ECOWAS trade is unique and influenced largely by the objective of the study, which is to establish the type of ECOWAS trade that is a good predictor of growth. The evidence from our findings support the theory that RTAs are a better catalyst to economic growth.

The purpose of this paper is to provide evidence on the importance of cross-border cooperation in the quality assurance of transnational education (TNE) by offering a comparative overview of how TNE is quality assured by both sending and receiving countries. Through this comparative analysis, it will be possible to appreciate the diversity of approaches to TNE. The paper also shows that for the foreseeable future, progress towards effective and effiicient quality assurance of TNE cannot rest on the hope of developing an internationally agreed framework, but it must rest on strengthening cooperation between quality assurance agencies operating within different national frameworks.

This paper looks at four key sending countries of TNE, the UK, Australia, the USA and Germany, considering the main drivers for out-going TNE, its main features and how it is quality assured. It then considers the same aspects from the perspective of receiving countries of TNE, looking at four key receiving locations, China, Dubai, Singapore and Hong Kong. It also offers an overview of some recent international initiatives aimed at fostering cross-border cooperation in the quality assurance of TNE.

In the backdrop of this overview of different approaches to TNE, this paper will conclude that for the foreseeable future it is not possible to develop an internationally agreed view and approach to TNE and its quality assurance. This conclusion allows the author to focus on the importance of cross-border cooperation amongst quality assurance agencies in sending and receiving countries for the effective and efficient quality assurance of TNE.

This is the first comparative study of different countries’ approaches to TNE and its quality assurance, taking into account both sending and receiving countries. It allows pointing to the key different features in different countries’ approaches and illustrates how these often relate to the underlining national strategic priorities and drivers for TNE (either in-bound or out-bound). It also allows the international community to realise that in the absence of a viable shared and agreed international framework for the regulation and quality assurance of TNE, it is of paramount importance to focus efforts on inter-agency cross-border cooperation in order to ensure that TNE continues to be of good quality and relevant to the respective communities.

The feasibility and desirability of reverse logistics in market-motivated contexts are examined in China. Interactions between the major barriers, that hinder or prevent the application of reverse logistics in China are analyzed. Management’s key task is to diagnose barriers to the application of reverse logistics that could be crucial to the organization’s future survival. Simultaneity, a value delivery system exists to create value for customers and environments by supplying needed products and services. Value delivery systems are at the heart of every firm and, more than anything else, determine that, whether the firm survives in the marketplace or disappears into bankruptcy or takeover. The processes and model of market-motivated reverse logistics value delivery system are discussed, and the processes content and model are presented. Simultaneity, based on the advantage of the Third Party Reverse Logistics Providers (3PRLs) and Outsourced Service Providers, an integrated evaluation model is built to select 3PRLs by using the integrated decision-making methods. Reflecting the comprehensive information requirement, the Analytic Hierarchy Process and entropy approaches are applied to calculate the objective weights. A new kind of relative similarity degree is established by combining the Euclidean distance with the grey correlation degree. An example demonstrates the model’s efficiency.

The purpose of this research is to study the Colombian avocado export industry, identify key insights associated with creating and sustaining the avocado value chain, and to understand the impact of the public policies affecting this industry.

The approach consists of two case studies to shed light on the opportunities and challenges of developing a sustainable avocado value chain in Colombia. One case deals with a vertically integrated business (Arcángel Miguel) while the other focuses on an association of small growers (Asohass). The analysis was informed by a series of interviews with key actors along the avocado supply chain to uncover the business strategies to move avocados to destination markets. The authors compare and contrast approaches to business development, international expansion, and role of public policies.

The authors found that the strategies followed by these organizations differ in means but aim for the same objective: maximize profits, improve environmental performance, and enhance the social wellbeing of growers. The authors found that each type of business model requires distinct public policies to succeed and different strategies to appropriately allocate efforts. The findings are relevant to other high-value crops and other Latin American countries with similar geographical and social characteristics.

These insights underscore the need of public policies tailored to the specific needs of the different actors in the value chain. The current emphasis on certifications and export markets works well for large agribusinesses, but smallholder growers need policies tailored to new investments in physical, human, and social capital.

This study contributes to the literature on avocado value chains in Latin America, emphasizing the challenges faced by the emergent Colombia avocado sector, a country that only began exporting this commodity in 2010.
