Professors S. Viswanathan and Arvind Sainathan in their latest research (presented at INFORMS Annual Conference, San Francisco, 2014) compared the performance of two key carbon control policies, carbon tax and cap-and-trade, in a firm-level, micro-economic, game theoretic model. They found th​at carbon tax, cap-and-trade as well as auction-based mechanisms for allocation of emission allowances all achieve the same level of social welfare for an economy. They are currently evaluating how the total social welfare to the economy can be improved by policies such as a green rebate (or rebate based on emission reductions) on income and value-added taxes.

Professor Chen Chien Ming has developed production frontier-based methodologies for evaluating and benchmarking corporate environmental & social performance,and has most recently published in the Strategic Management Journal. He is currently engaged in several research projects about creating environmental sustainability in several operations contexts. In one study, he investigates the relationship between supply chain structure and carbon efficiencies of a firm. He found that firms with limited scope and high focus on their key value-added processes tend to achieve better carbon efficiency in their supply chains. In another study, he and his coauthor look to build theories on how a firm’s carbon performance is associated with its customers’ carbon performance. The initial results reveal that customers of a firm may influence their common buyer through their market power, purchasing power, as their reputation as environmental leaders. In another study, he examines the antecedents of investments in carbon abatement technologies. He and his coauthor find that firms invest more in riskier projects when they perceive a higher regulatory risk about production processes and customer’s response, while firms tend to reduce investment in riskier projects (and invest more in short-term projects) when they perceive a higher regulatory risk about product eco-labeling.

Other research that has been undertaken in sustainable operations includes Sustainable Procurement and Supply Chain Management (Fang Liu), Socially Responsible Supply Chains (Fang Liu, S. Viswanathan), Humanitarian Operations (Fang Liu), and Remanufacturing and closed loop supply chains (S.Viswanathan), benchmarking of corporate environmental performance (CM Chen).
