Machine learning systems are increasingly used for automated decision making; for example for designing economic policies and for identifying qualified candidates in education or finance. When designing such systems, it is important to consider how changes in the target population or the environment affect the performance of the systems. Moreover, it is important to consider how these systems influence the societal forces that impact the target population. In this talk, I will discuss three lines of my research that take this dynamical and economic perspective on machine learning: learning parameters of auctions in presence of changes in user preferences, learning admission and hiring classifiers that encourage candidates to invest in valuable skill sets, and augmenting human decision making in hiring and admission to increase the diversity of candidates.
