Sanitary requirements, geopolitical crises, and other factors that increase price volatility have an impact on the organization of markets and changes in investment policies and business strategies. The COVID-19 pandemic interrupted the trade of chicken meat, due to the drastic reduction in the circulation of goods, interrupted the supply of production chains, changed consumption habits, and made it difficult to reorganize business due to the slow resumption of operations by suppliers of inputs and in distribution logistics. The magnitude of these impacts has not been studied despite the high relevance of this economic dimension and the managerial implications for sector governance and trade management. The purpose of this study was to evaluate the economic impact of the COVID-19 pandemic on the production costs and competitiveness of the Brazilian chicken meat production chain. The methodology consisted of the detailed collection of information and data on private and social prices carried out using the Policy Analysis Matrix (PAM) method. The competitiveness coefficients and policy effects in the Brazilian broiler production chain before (2015) and during (2022) the COVID-19 pandemic were quantified and compared. Generally, the significant increases in the production costs of chicken meat (30.49%) caused a decrease in total factor productivity (−19.54%), a reduction in gross revenue, and lower tax collection. The pandemic has reduced the profitability of the chicken production chain in Brazil by 32.31%, reduced the competitiveness of exports, and worsened other economic indicators of the production chain. To the best of our knowledge, no other study has investigated the impacts of the COVID-19 pandemic on the competitiveness of the Brazilian chicken meat production chain. The PAM method allows for prices paid and received to be updated in real terms in projects representative of Brazil, the world leader in exports. This information is important for both national and international stakeholders. Additionally, this model is applicable to other meats traded in the international market, as it provides greater precision in business management and can estimate the impacts of risks on the availability or quality of food and health crises with robust results.

In order to reduce poverty and achieve Goal 1 of the 2030 Agenda for Sustainable Development, countries’ foreign trade flows must be a driving force for productive activity, as proposed by the WTO-led (World Trade Organization) Aid for Trade initiative. This work analyzes the evolution of international trade in goods and services between Africa’s Least Developed Countries and customers and suppliers from other countries between 2005 and 2015, based on the information provided by UNCTAD and the World Bank. The results confirm a greater degree of trade openness and especially an increase in service imports. Overall, the data show that the purchases made in the international market have a greater marginal effect on GDP than sales, leading to the conclusion that changes in trade policy are needed, at both international and national level. Actions should be aimed at ensuring that the growing integration of these economies in the world trade system does not result in continued deficits in the trade balance but, on the contrary, does contribute to GDP growth and poverty reduction.

The economic sustainability of agro-industrial systems expresses firms’ competitive capacity and can be achieved with greater innovation, productivity and price management. The emerging olive oil agro-industrial systems in Brazil lack the information on economic and financial performance that they need to grow. The objective of this study is to evaluate the financial viability of an olive grove and the competitiveness and economic sustainability of the extra virgin olive oil using primary data collected and analyzed by the policy analysis matrix method. The main indicators considered with respect to current production and commercialization techniques are private and social profitability, added value, remuneration of domestic factors and total factor productivity. It is concluded that the emerging extra virgin olive oil agro-industrial system in Brazil has financially viable olive groves, significant competitiveness and presents economic sustainability.
