Values and Agency in Algorithmically Optimized Ecosystems

Abstract

This talk presents my research on how algorithmic systems influence decision-making in AI-driven environments. I investigate scenarios involving compounded automated decisions (e.g., repeated credit denials), automated work scheduling, and recommendation systems that affect what people purchase, how they manage their time, and how institutions set objectives in multi-stakeholder settings. These systems could then potentially affect people’s agency and core values, producing uncertainty and unexpected outcomes. Through economic modeling, simulation, and organizational analysis, I study how these systems shape individual autonomy (e.g., consumer choices), financial outcomes, and behavior over time.

One part of my talk focuses on deterministic systems like optimization processes and examines how they can potentially amplify financial instability in digital economies. I design methods that incorporate feedback, long-term effects, and stakeholder tradeoffs directly into optimization as a dynamic and temporal process (instead of setting a static multi-objective optimization formulation). Another part of my work explores generative AI and its impact on human reasoning and preferences. In combination, the goal of these projects is to contribute to broader inquiries into how algorithmic systems alter human values and agency in terms of economic coordination and human decision-making.

About

Having just completed her PhD in Computer Science at Brown University (advised by Professor Suresh Venkatasubramanian), Pegah Nokhiz is a Postdoctoral Fellow at the Digital Life Initiative, Cornell Tech. She was an affiliate of Brown's Center for Technological Responsibility, Reimagination and Redesign (CNTR) at the Data Science Institute.

Pegah's research work has focused on the long-term effects of automated decision-making (on artificial societies), fairness in machine learning, bridging quantitative and qualitative methods from other disciplines by analyzing and quantifying interdisciplinary notions (to gauge the ethical and social impacts of AI tools), and econometric approaches to simulating individual behavior. Methodologically, Pegah's work draws on frameworks and notions from a variety of related disciplines such as moral philosophy, social sciences, and econometrics. Her work has been published in interdisciplinary venues such as Fairness, Accountability, and Transparency (FAccT) and Artificial Intelligence, Ethics, and Society (AIES).
