Date:  Monday, September 25th, 2017

Speaker: Dale Griffin, UBC Sauder School of Business
Topic: "Bias(es) in Probabilistic Forecasting"
Time: 2:30PM - 4:00PM
Place: Henry Angus 969

Abstract: For (too) many years, I have studied biases in forecasting with the goal of reducing the vast forest of behavioural biases into a manageable few.  In this rough and informal seminar, I will introduce the evidence for the existence of "one bias that rules them all".  I will briefly discuss some experimental studies from my own lab, as well as a broad set of data from others' field studies of physicians and meteorologists.  Finally, I will discuss new data from research on asset pricing drifts with Murray Carlson that seem to support the general bias proposal.  My goal is to change the way that you think about subjective probability!




Date:  Monday, October 2nd, 2017

Speaker: Robert Swinney, Duke University
Topic: "Managing Social Responsibility in Multitier Supply Chains"
Time: 2:30PM - 3:30PM
Place: Henry Angus 969

Abstract: We study the management of social responsibility in a three-tier supply chain in which a Tier 2 supplier sells to a Tier 1 supplier, which in turn sells to a Tier 0 buyer. The Tier 2 supplier potentially violates social and environmental standards, resulting in harm to the Tier 0 and 1 firms. Each member of the supply chain can exert effort to improve the responsibility in Tier 2, and the efforts of Tiers 0 and 1 are substitutable with one another and complementary to the efforts of Tier 2. We show that under these conditions, the buyer’s optimal strategy is one of extremes, consisting of direct control (only Tier 0 works with Tier 2), delegation (only Tier 1 works with Tier 2), or no effort (neither firm works with Tier 2). Given that delegation is a much simpler and more scalable strategy for buyers with extensive supply chains, we analyze how buyers can increase the relative attractiveness of this strategy, e.g., by carefully selecting suppliers. When control is optimal, we determine its relative value and discuss how resource-constrained buyers can prioritize the direct control of responsibility management where it has greatest value amongst Tier 2 suppliers. We also examine how pressure from external stakeholders (consumers, NGOs, and governments) influences the buyer's optimal strategy and the level of responsibility in the supply chain.



Date:  Monday, October 16th, 2017

Speaker: John Birge, The University of Chicago, Booth School of Business
Topic: "Dynamic Learning in Strategic Pricing Games"
Time: 2:30PM - 3:30PM
Place: Henry Angus 969

Abstract: In monopoly pricing situations, firms should optimally vary prices to learn demand.  The variation must be sufficiently high to ensure learning.  In competitive situations, however, varying prices provides information to competitors and may reduce the value of learning.  Such situations may arise in the pricing of new products such as pharmaceuticals.  The talk will discuss how this effect can be strong enough to stop learning so that firms optimally reduce any variation in prices and choose not to learn demand.  The result can be that the selling firms achieve a collaborative outcome instead of a competitive equilibrium.  The result has implications for policies that restrict price changes or require disclosures.
