Jan 27 – David Lanter – Enabling Data Protection by Design with Data Provenance Metadata”

January 17, 2023 By Aleksi Aaltonen

Time: Friday, 27 January 2023, 10:30–12:00
Room: LW420

Abstract

Privacy by design is part of the larger “data protection by design” achieved by security architecture and focuses on leveraging privacy protection principles, controls along with privacy enhancing technologies into the design of information management technologies and systems. The European Union’s General Data Protection Regulation (GDPR) makes protecting privacy and personal data a default requirement for system and service behavior of systems and services that must be thought through and designed in. Although the concept of privacy and data protection by design found its way into GDPR, the authors of the legislation acknowledged that “its concrete implementation remains un-clear”. Data provenance information, however, offers a way to meet these requirements. This presentation provides an overview of pioneering research the author conducted to combine information systems and related processing workflows with digital provenance metadata capture and processing to augment scientific reproducibility, comparison, trust or to otherwise improve information system assisted decision support.

Mar 18 – Hemant Bhargava to present “Platform Ecosystems: Co-Dependence, Scale, Design”

Platform Ecosystems: Co-Dependence, Scale, Design

by

Hemant K. Bhargava

Professor
Jerome and Elsie Suran Chair in Technology Management
Director, Center for Analytics and Technology in Society
Graduate School of Management
University of California Davis

 

Friday, Mar 18

11:00 am – 12:30 pm

In-person: 1810 Liacouras Walk, Room 420

Abstract:

I will discuss a couple of recent papers on platform economics, that aim to develop a highly general and extensible modeling architecture for analyzing the economics of platform ecosystems, specifically studying issues such as:

What factors govern the scale of the platform ecosystem? How are platform scale and power affected by: (i) Complementors’ production attributes? (ii) Platform’s economic + technical design, and strategic choices? (iii) Platform market structure? (iv) Nature of dependence between a platform and its complementors?

​How does ecosystem structure influence distribution of power (and revenue) between platform and complementors?

How will ecosystem structure, and platform-complementor co-dependence, evolve?

The two papers provide the basic modeling infrastructure, applied to platforms that monetize through advertising and through user fees. I will then discuss how the models can be adapted to address questions related to platform power, revenue-sharing, and platform regulation.

Abstact:

Online matching platforms require new approaches to market design since firms can now control many aspects of search and interaction process through various IT-enabled features. While choice structure—the size of choice set and the number of choices a platform offers to its customers—is one of the key design features of online matching platforms, its impact on engagement and matching outcomes remains unclear. In this study, we examine the effect of different choice structures on the number of choices and matches on the platform by conducting a randomized field experiment in collaboration with an online dating platform. Specifically, we design four treatment groups with different choice structures where users can only interact with other users in the same group, select users who are in a similar age range and live in the same geographical location, and randomly assign them to each treatment group. We find that providing higher choice capacities to male and female users have a different effect on choice behaviors and matching outcomes. Moreover, while increasing the choice capacity of male users yields the highest number of choices, increasing the choice capacity of female users is the most effective way to increase matching outcomes. Structural analysis further reveals the underlying mechanisms of choice behavior and matching results, suggesting that users significantly decrease the number of choices after receiving a choice from other users and the effect of the choice capacity on matching outcomes differs by gender. We further provide a counterfactual analysis that explores optimal choice structure design depending on the gender ratio of the online dating platform.
