Little, C., Felzensztein, C., Gimmon, E., & Munoz, P. (2015). The business management of the Chilean salmon farming industry. Mar. Pol., 54, 108–117.
Abstract: This study reviews and explores the salmon farming industry management in an emerging economy context, in the light of environmental responsibility, restorative justice and moral reengagement. Strategic information were gathered, performing in-depth interviews with CEOs and other key senior executives, to analyze the managerial behavior regarding environmental care and moral engagement to industry production standards. The results reveal issues related to firms and government roles on setting industry standards and enforcing them. Firms required to be perceived as renewed in order to receive help from the government and convince the market on their IPOs. Government lack of technical strength and capacity to reestablish order forced the industry firms association to propose a new regulatory standard. But this new order seems not to be satisfactory and this industry will continue to be on the verge of a crisis. (C) 2015 Elsevier Ltd. All rights reserved.

Moreno, E., Rezakhah, M., Newman, A., & Ferreira, F. (2017). Linear models for stockpiling in open-pit mine production scheduling problems. Eur. J. Oper. Res., 260(1), 212–221.
Abstract: The open pit mine production scheduling (OPMPS) problem seeks to determine when, if ever, to extract each notional, three-dimensional block of ore and/or waste in a deposit and what to do with each, e.g., send it to a particular processing plant or to the waste dump. This scheduling model maximizes net present value subject to spatial precedence constraints, and resource capacities. Certain mines use stockpiles for blending different grades of extracted material, storing excess until processing capacity is available, or keeping low-grade ore for possible future processing. Common models assume that material in these stockpiles, or “buckets,” is theoretically immediately mixed and becomes homogeneous. We consider stockpiles as part of our open pit mine scheduling strategy, propose multiple models to solve the OPMPS problem, and compare the solution quality and tractability of these linear-integer and nonlinear-integer models. Numerical experiments show that our proposed models are tractable, and correspond to instances which can be solved in a few seconds up to a few minutes in contrast to previous nonlinear models that fail to solve.

Pietrobelli, C., Marin, A., & Olivari, J. (2018). Innovation in mining value chains: New evidence from Latin America. Resour. Policy, 58, 1–10.
Abstract: The paper investigates new opportunities for innovation and linkages associated to mining activities in Brazil, Chile and Peru. Three types of opportunities were researched: demand side, supply side and local specificities. The last source of opportunities is key for natural resource related activities. The evidence shows that an increasing demand is introducing important incentives for innovation and local suppliers. Nevertheless, a hierarchical value chain, dominated by few large firms, and poor linkages is blocking the diffusion of innovations and hindering suppliers' development. The emergence of a group of highly innovative suppliers, which were identified in the three countries, is explained mostly by new technological and knowledge opportunities, which are not exploited by large incumbents and open spaces for new entrants. Local specificities are also key in the explanation of local suppliers. It remains a challenge however, how these, most of which were created to satisfy local needs, will move from local to global.
