摘要：We investigate whether a firm's risk pooling affects its analysts' forecasts, specifically in terms of forecast accuracy and their use of public vs. private information, and how risk pooling interacts with a firm's position in the supply chain to affect analysts' forecasts. We use a social network analysis method to operationalize risk pooling and supply chain hierarchy, and find that risk pooling significantly reduces analysts' forecast errors and increases (decreases) their use of public (pr...

摘要：We analyze a firm's investment in environmental process improvement (EPI) to reduce the environmental impact (EI) of its manufacturing processes in relation to various internal firm characteristics and in response to different external regulatory drivers. We provide a deep understanding of how these internal and external forces cause the firm to pursue EPI earlier or later in the planning horizon and at an increasing or a decreasing rate over time. In particular, we show how a regulator can dr...

摘要：When designing an assortment, a fundamental trade-off exists between estimating consumer behavior more precisely and solving the corresponding optimization problem efficiently. For instance, a mixture of logit model can closely approximate any random-utility choice model; however, it is not suitable for optimization when the number of customer segments and the number of products considered are large. As many companies are using big data and marketing analytics toward microsegmenting consumers,...
