Titel des Vortrags: How does my neighbour think? Mental models and opinion dynamics update rules

Abstract:

Most models in opinion dynamics are created from simple ad-hoc rules. Different models match distinct applications better and very little work exists on how they relate to each other. In this talk, I will show how we can define general models from a framework for how agents communicate and how we can obtain update rules from agent mental models and simple uses of the Bayes theorem. That allows us to easily include specific aspects of any applications we might be interested in as well. And we can also understand, up to some underdeterminacy, which mental models seem to correspond to each of the update rules we find in the literature.

Opening conference of the Research Group
“Economic and Legal Challenges in the Advent of Smart Products”
OCTOBER 4-6, 2021

The Center for Interdisciplinary Research (ZiF) at Bielefeld University is pleased to announce the opening conference of its new Research Group “Economic and Legal Challenges in the Advent of Smart Products”. The conference aims to provide a platform for both disciplinary and interdisciplinary exchange on topics related the development and legal regulation of smart products, as well as factors determining their acceptance and diffusion. Questions of particular interest include:

- How are innovation activities of firms affected by the legal environment?
- How do data privacy concerns affect the behaviour of consumers, firms, and policy makers?
- How do specific features of smart products (such as autonomous activity, data collection, opacity as a result to deep learning) affect consumers’ trust in these products and their willingness to adopt?
- Which empirical and theoretical approaches are suitable for analyzing the (expected) diffusion of smart products?
- How to deal with the major regulatory challenges arising in age of smart products?

We are mainly inviting papers with an economic and/or legal perspective on such questions (thereby using various methodological approaches), but we also welcome submissions from other disciplines such as philosophy, sociology, and data sciences. Apart from contributed sessions, the conference will also feature two keynotes, as well as a panel discussion with policy makers and industry leaders.

Keynotes: Eric Talley (Columbia University) and Mireille Hildebrandt (Vrije Universiteit Brussel)

Organizing committee: Herbert Dawid (Bielefeld University), Sabine Gless (University of Basel), Gerd Muehlheusser (University of Hamburg)

Fees, costs and registration: There is no participation fee, but participants need to register for the conference in advance. ZiF will cover the cost for travel and accommodation for presenters and discussants according to its regulations.

Conference format: As of now, we plan that the conference takes place in person at ZiF. Should travel restrictions still apply by then, we will be able to switch to a hybrid or even fully online format.

Submission: Please submit either a full paper or an extended abstract (written in English, preferably in PDF) by MAY 1, 2021 to smart-products@uni-bielefeld.de

Titel des Vortrags: Bayesian Decision Making

Abstract:

There are often high expectations on the business impact that data science can produce. Unfortunately, various barriers often hinder the full realization of that impact, starting with communication challenges between different parts of the organization with different backgrounds. To bridge this chasm, data scientists and stake-holders should agree on a business relevant loss function to optimize. This way, any improvements in the model can directly be measured in their impact on the bottom line.
In this talk, I will show how probabilistic programming frameworks like PyMC3 can be used to solve an applied problems with an example from capital allocation. This approach allows us to accurately and flexibly map a real-world problem to a statistical model that can be quickly iterated and improved on. I will then show how the results of such a model, which are usually arcane and non-actionable posterior probability distributions, can be coupled with a loss function based on business mechanics, to (i) derive business related outcome measures, and (ii) suggest the optimal decision to make, rather than inform it.

Title: The person brand effect and the role of product innovation: Consumers' stereotypes influence evaluations of persons and their products

Abstract: A series of field and laboratory experiments found that consumers' stereotypes influence perceptions of a person who creates a product (i.e., a person brand) as well as post-trial evaluations of the product. Consistent with schema congruity theory, consumers evaluated a product created by a person who was counter stereotypical on one dimension (e.g., gender but not ethnicity) more positively than the stereotypical creator's product. Consumers' cognitive resources during trial are a boundary condition on improved evaluations of a unidimensional deviate’s product. In contrast, consumers evaluated a product created by a person who was counter stereotypical on two dimensions (e.g., gender and ethnicity) most negatively. Product innovation moderated these effects such that an innovative product created by a bidimensional deviate was evaluated similar to that of the stereotypical creator's product. These findings have implications for branding, product innovation, schema congruity theory and stereotyping.

Title: Integration of Machine Learning and Optimization for Supply Chain Optimization

Abstract: We are trying to develop the AI techniques that can be explained by an automatic synthesis of decision-making models through the integration of machine learning and optimization. By constructing a feedback loop of machine learning and optimization, a closed-loop data-driven system that can improve the machine learning accuracy and significantly reduce the computational time required for optimization through machine learning methods even in a shortage of teaching data. From the viewpoint, our recent topics on dynamic multi-commodity network design problem, virtualization of supply chains, mass customization of product design and supply chain planning, inverse optimization for scheduling problems, imitative learning will be discussed.

Title: Platform Operations Research: Foundations and the Cases of Coup Scooter Sharing and Quicargo Collaborative Trucking

Abstract: Over the last decade, platforms have emerged in numerous industries and often transformed them, which poses new challenges for operations research. Platform providers mostly do not have immediate control over the physical resources to move people or goods. They often operate in a multi-sided market setting where it is crucial to design clear incentives to motivate a third-party to engage in an adhoc kind of collaboration. As a consequence, collaboration incentives become an integral part of decision support models for platform providers, and they need to be developed on an operational planning level to be applied in a dynamic way. Naturally, this involves a trade-off between the interests of platform provider, customers, and various transportation service providers. In this work, we investigate the real-word case of Coup scooter sharing and propose a dynamic pricing approach that engages users in fleet management operations such as charging and repositioning of vehicles. First results indicate that this approach effectively increases vehicle utilization and revenues. As a second real-world case, we look at the platform provider, Quicargo, who operates as an intermediary between shippers and carriers in a less-than-truckload (LTL) business. We introduce a planning model that minimizes the price this platform pays to its carriers and enforces collaboration incentives for carriers. We explore possible policies to be implemented by the platform and find that their business even remains profitable when the platform guarantees increased profit margins to their carriers as incentives.
