Soybean Expansion in Brazil’s New Agricultural Frontier: Barter, Production Cos...
Brito, T.; Fragoso, Rui; Santos, L.; Silva, A. A. F.; Justino, G.; Lima, J. R. D. S.; Aranha, J.Despite the global relevance of soybean production and Brazil’s leadership in this sector, most studies have focused on established producing regions such as south-central Brazil, while little attention has been given to new frontiers. In particular, the role of barter, costs, price volatility, and local socio-economic aspects remain underexplored. Therefore, this study analyses production costs, market volatil...

Fragoso, Rui; Scazziota, Vanessa; Guerrazzi, Luiz; Quaresma, Rui; Casas Novas, JorjeThe purpose of this paper is to assess the moderating effects of motivating and contextual factors on the relationship of innovation ambidexterity and firm performance. A theoretical framework was developed and tested using survey data from a sample of the Global University Entrepreneurial Spirit Students’ Survey (GUESSS). The results suggest a positive effect of ambidexterity on firm performance, which is posi...
A multi-objective simulation-based decision support tool for wine supply chain ...
Viera, António A.C.; Figueira, José Rui; Fragoso, RuiSustainable Supply Chain Network Design (SCND) poses a complex challenge, as it often requires trade-offs in decision-making. The problem becomes even more challenging when there is a need to integrate risk management into the design process. It is steered by this challenge that the purpose of the paper is twofold. First, it proposes a Simulation-Based Decision Support System (SBDSS) for a real case study of a ...

Exploring Firm Performance of the Wine Industry in Portugal Using a Two-Stage E...
Fragoso, Rui; Vieira, AntónioThis article aims to assess the firm performance of the wine industry in Portugal. A two-stage efficiency analysis was applied to a sample of firms from the Amadeus database, where a Data Envelopment Analysis (DEA) and a fractional regression model were used to quantify efficiency and to determine the influence external environmental factors have on it. The results highlighted a dichotomy in terms of resources ...
Efficiency analysis of the Portuguese wine industry using accounting and operat...
Fragoso, Rui; Vieira, AntónioWine is an integral part of the economy and culture of many countries. Despite that, in Portugal – one of the main wine-producers – there is a lack of empirical evidence regarding the efficiency of these firms. Thus, the purpose of this article is to assess such efficiency using a four-step approach, which includes the selection of relevant financial and operational variables, a cluster analysis for the identif...
