Optimizing two-sided assortments through adaptivity and approximation.

Sammanfattning

The article discusses the challenges faced by two-sided matching platforms due to choice congestion among popular options. It introduces a framework for assortment optimization to maximize matches by designing assortments and their presentation order. The study compares different policy classes, showing adaptivity gaps between them. Results include approximation algorithms for various policy classes under different choice models.

Statistik

Gap between one-sided static and adaptive policies is 1 - 1/e.
Gap between one-sided adaptive and fully adaptive policies is 1/2.
Approximation factor of 0.066 for multinomial-logit models under fully static policies.

Citat

"There exists a polynomial time policy that achieves a 1/4 approximation factor within the class of policies that adaptively show assortments to agents one by one."
"The worst policies are those who simultaneously show assortments to all the agents."
"Balancing relevant options with reducing choice congestion leads to better market outcomes."

How do these findings impact real-world two-sided platforms

The findings on adaptivity gaps in two-sided assortment optimization have significant implications for real-world platforms. By understanding the value of adaptability in policy design, platforms can optimize their matching outcomes and improve market efficiency. For example, knowing that adaptive policies outperform static ones can guide platform designers to prioritize flexibility and responsiveness in their decision-making processes. This insight can lead to better user experiences, increased engagement, and ultimately higher success rates in forming matches between users.

What are potential drawbacks of focusing on fully static policies

Focusing solely on fully static policies may have several drawbacks in the context of two-sided platforms. One major drawback is the lack of adaptability to changing preferences or market conditions. Static policies do not take into account real-time feedback from users' choices, potentially leading to suboptimal matching outcomes and reduced user satisfaction. Additionally, fully static policies may struggle to address choice congestion among popular options efficiently, as they are unable to tailor assortments based on individual agents' behaviors.

How can the concept of adaptivity be applied in other optimization problems

The concept of adaptivity demonstrated in two-sided assortment optimization problems can be applied across various other optimization domains. In supply chain management, for instance, adaptive strategies could help companies adjust production levels based on demand fluctuations or supply chain disruptions. In marketing campaigns, adaptive algorithms could personalize content delivery based on customer interactions and responses. Overall, incorporating adaptivity into optimization problems allows for more dynamic decision-making processes that respond effectively to changing environments and maximize desired outcomes.
