报告A摘要:As business firms pay more attention to data and data driven decision making, more data are collected through different techniques and datasets can become very large. Almost all datasets include categorical data in nominal scale. Researchers and practitioners usually use these categorical data when building linear models. Different types of linear models and different ways of constructing linear models are briefly reviewed. Characteristics of categorical variables are discussed and examples of categorical variables in linear models are provided. Correct and incorrect approaches for coding categorical variables in linear models are analyzed. Indicator variables used to represent categorical variables are demonstrated in a regression model through an example. Limitations of indicator variables are also discussed

报告B摘要:We analyze the sourcing decision of a brand-name firm facing two suppliers: a licit domestic supplier and an oversea supplier who potentially becomes a counterfeiter if the brand-name firm fails to engage it. We obtain the optimal sourcing strategy of the brand-name firm and identify the conditions under which the brand-name firm can prevent the overseas supplier to become a counterfeiter. Specifically, if the penalty from law enforcement to the counterfeiter is high, the brand-name firm engages the overseas supplier by single sourcing from it. If the penalty is not high and the difference in production costs between two suppliers is low, the brand-name firm engages the overseas supplier by dual sourcing. With high perceived quality of the counterfeit product, if both the penalty and the difference in production costs are low, the brand-name firm fails to engage the overseas supplier by single sourcing from the domestic supplier. We also examine how factors, such as the penalty from law enforcement and the quality discount factor, affect firms’ profits, consumer surplus and social surplus.

报告C摘要:Recently, Chinese firms have begun to deploy popular mobile apps (e.g., WeChat) into their supply chain practices to improve demand visibility. These efforts rely on consumers to scan the products they purchase using these apps,  which we refer to as consumer scanning technology (CST).  CST can be an alternative to conventional inter-organizational information technology (IOIT) that relies on collaboration between supply chain firms.  We develop a theoretical model to examine the value of CST to learn supply chain (demand) information. In this model, an upstream supplier bypasses the downstream retailer and employs CST to directly collect end scan information from consumers who are incentivized with a reward for participating. The theoretical analysis of the model demonstrates both operational and strategic values of CST. On the operational level, noticing that the scan information gathered by CST is a censored version of the true information, we develop a simple and effective approach for the supplier to learn the true information from the censored one, and then investigate the learning efficiency of our approach and the optimal reward decisions. On the strategic level, we examine the equilibrium choice of IOIT and CST within supply chains and investigate their interplay.  Contrary to conventional view, we find that the availability of CST may expand (instead of suppressing) the use of IOIT within supply chains. Using real-life data from a manufacturer that has implemented a CST program for learning demand information, we show that the value of CST can be substantial.
