Firms, such as online retailers, typically have plenty information on the visits andtransactions made by their own customers at their own sites. Yet their efforts of applying Big Data technology in sales forecasting is limited by the lack of information from external sources, i.e., firms usually do not know the activities of the customers at other firms. Some third party data collectors have seized the opportunities by providing firms with customer behavior (including visits and purchases) information from external sources. A challenge, however, is that the value of such external data is largely unknown. In this paper, we propose a novel framework and conduct a series of tests to examine the value of customer behavior information from external sources as supplement to firms’ internal data in the context of sales forecasting. The empirical results suggest that higher forecasting accuracy is usually achieved by combining data from both internal sources and external sources than utilizing internal data alone, yet the values of external data vary by their sources and may not increase monotonically with the size of the data.
