The concepts of bioeconomy, green economy and circular economy share the common objective of developing a sustainable economy, and they attract enormous political, academic, social and business interest. However, an analysis of these concepts in the fields of economics and business management is lacking. The objective of this article is to classify the publications on these topics by subject of study, to analyse trends in publications and to guide researchers interested in selecting articles. The review was performed using Scopus for the period 1960 to 2017. Four hundred and forty-nine publications were obtained and classified into 17 categories. The results show that the existing literature is rich in analysing implemented policies and issues related to the strategies and organizational models of companies looking for a more sustainable path, and research in China and the European Union is highlighted. However, there is still a long way to go in researching implemented case studies and evaluating the economic impact of these concepts. For this to happen, the need to promote, encourage and support companies to implement cleaner production and approach a more sustainable path must be prioritised. Possible gaps in current research that allow future lines of work are also identified.

Ghana shows remarkable differences in employment and welfare between the southern and northern regions. The promotion of policy focus on the development of the northern regions requires the elaboration of specific databases describing the regional economies. Hence, this work outlines the construction of a Social Accounting Matrix (SAM) for Ghana for the year 2015 with a high disaggregation of sectors, household income groups and education levels across 10 administrative regions. Linear multisectoral models have been applied to this SAM to estimate socio-economic impacts of potential final demand policies down to a regional level in the Ghanaian economy. Further on, the structural path analysis is used to investigate the role played by different agriculture commodities in transmitting income to different types of households. The results allow for an identification of the most suitable sectors to be promoted due to their ability to generate the highest increases in output, employment and value added in the rest of the economy, as well as those with a significant impact on household income generation. As a result, the primary sector will play a key role in the economic and employment growth of the country. Notably, sorghum and millet, pulses, tobacco, cotton and fibres can be considered favourable crops for development in the Northern region.

The bioeconomy emerges as an opportunity to focus on a more sustainable economy, avoid dependence on non-renewable resources and help to mitigate negative environmental impacts. The bioeconomy is considered a priority for the European Union and for Spain, which launched its strategy in 2016. To promote the Spanish bioeconomy, the impact and variables that may influence its development must be known. While previous works have analyzed the domestic sectors, this paper focuses on analyzing the economic importance of Spanish bioeconomy products and on the influence of and the existing links between the foreign sector and the rest of the economy. For this purpose, we apply two different methodologies based on linear social accounting matrix (SAM) models. The linkages show that many bioeconomy products have the potential to promote the rest of the economy and the values of some product multipliers become more significant due to their import dependence. These results enable us to know the structure of the Spanish bioeconomy and the relationships within its account. This analysis is a useful tool for developing policies focused on fostering the bioeconomy and economic growth.
