In particular, this “strategic openness” can be applied by organizations in transforming industries – where certain hardware or software...

The design of targeting policies is fundamental to address a variety of practical problems across a broad spectrum of domains from e-commerce to politics and medicine. Recently, researchers and practitioners have begun to predict individual treatment effects to optimize targeting policies. Although different research streams, that is, uplift modeli...

Choosing the correct method to predict the incremental effect of a treatment on customer response is critical to optimize targeting policies in many important applications such as churn management and patient care. Two research streams, uplift modeling and heterogeneous treatment effects (HTE), have emerged that scrutinize the incremental effect of...

While the automotive industry is in the midst of fundamental transformations, Tesla has repeatedly applied strategic resource openness initiatives (e.g., open patents, open-source code, open infrastructure). Existing resource openness perspectives associate such initiatives with anticipated advantages regarding value appropriation or profitability...

“Grand challenges” can provide an important orientation regarding whether research deals with societally relevant problems. Yet, many IS scholars have claimed that IS research is often dealing with issues that are of rather little relevance to societal grand challenges. In this “research-in-progress” study, we examine to which degree IS research is...

When conducting direct marketing activities, companies strive to know whom to target with a marketing incentive to maximize the campaign effect. For example, which customer should receive churn prevention incentive to minimize overall churn rate? Uplift modeling is a promising approach to answer such a question. It allows to separate customers who...

In the air cargo context, pallet loading faces substantial constraints and item heterogeneity. The stability constraint in the pallet loading problem is highly important due to its impact on the efficiency, security, and resulting costs of an air cargo company. In information systems that support pallet loading, physical simulations provide a reali...

Several leading firms have used the Internet to open (for free and public use) some of their most valuable resources (e.g., code, patents, APIs). Examples of such ‘resource openness’ range from Facebook’s APIs, to Google’s Android source code, and Tesla’s electric car patents. Resource openness appears to contradict the tenets of conventional theor...
