“…Particularly when local producers have not yet achieved the standards required to serve foreign markets in new, value-added products, public procurement can play a pivotal role in strengthening their competitiveness (e.g., Chalaby, 2017;Gao et al, 2019). More specifically, public procurement can accelerate domestic firms' ability to achieve economies of scale and develop advanced production technologies, while enabling own-brand development, initially for local and then subsequently foreign markets (see e.g., Butollo & Ten Brink, 2018). As evidenced in Table 4, the state's buyer role can also be particularly effective in strengthening social and environmental standards, requiring the adoption of Ethical Sourcing Policies -as in the case of Transport of London described in Martin-Ortega and O'Brien (2017); or by ensuring sustainable inputs (certified wood) are used in manufactured products, such as the case of school furniture production in the Oaxaca region (see Klooster & Mercado-Celis, 2016).…”
