In this dissertation, we study a supplier's operational decisions for supply chain optimization considering corporate social responsibility implementation and live- streaming channel introduction. Both essays start from analytical models that are inspired by observations, and we explore how different parameters affect the supplier's decisions through extensive numerical studies. In the first essay, we notice that cost auditing is becoming an increasingly important tool to improve supply chain efficiency and mitigate the influence of information asymmetry. We study how cost auditing indirectly influences retailer and supplier's behavior in social responsibility. We also discuss the potential negative social responsibility externalities of conducting an audit and the managerial insights. Finally, we find that customers' attitude towards different products changes retailer and supplier's social responsibility preference. In the second essay, we are interested in a new trend where suppliers today adopt live-streaming channels for online shopping. We analyze the trade-off between potential market demand and channel competition by introducing live-streaming channel and discuss the impact of live-streaming channel on supply chain optimization. As a result, both essays shed light on how suppliers respond to downstream companies' operational decisions.
