Title: After Great Disasters
Speaker: Robert Olshanky
Date/Time: September 07, 2017 – 14:00
Location: RTH 324
Major natural disasters are rare, but their aftermath can change the fortunes of a city or region forever. This book and its companion Policy Focus Report (co-authored with Laurie Johnson) identify lessons from different parts of the world to help communities and government leaders better organize for recovery after future disasters. The authors consider the processes and outcomes of community recovery and reconstruction following major disasters in six countries: China, New Zealand, India, Indonesia, Japan, and the United States. Post-disaster reconstruction offers opportunities to improve construction and design standards, renew infrastructure, create new land use arrangements, reinvent economies, and improve governance. If done well, reconstruction can help break the cycle of disaster-related impacts and losses, and improve the resilience of a city or region.

Title: Informing Ex-Ante Event Studies With Macro-Econometric Evidence on the Structural Policy of Terrorism
Speaker: Dr. Jasson Nassios & Professor James A. Giesecke
Date/Time: December 02, 2016 – 14:00
Location: RGL 209
Economic consequence analysis is one of many inputs to terrorism contingency planning. Computable general equilibrium (CGE) models are being used more frequently in these analyses, in part because of their capacity to accommodate high levels of event-specific detail. In modeling the potential economic effects of a hypothetical terrorist event, two broad sets of shocks are required: (1) physical impacts on observable variables (e.g., asset damage); (2) behavioral impacts on unobservable variables (e.g., investor uncertainty). Assembling shocks describing the physical impacts of a terrorist incident is relatively straightforward, since estimates are either readily available or plausibly inferred. However, assembling shocks describing behavioral impacts is more difficult. Values for behavioral variables (e.g., required rates-of-return) are typically inferred or estimated by indirect means. Generally, this has been achieved via reference to extraneous literature or ex-ante surveys. In this talk we describe a new method. We elucidate the magnitude of CGE-relevant structural shifts implicit in econometric evidence on terrorist incidents, with a view to informing future ex-ante event assessments. Ex-post econometric studies of terrorism by Blomberg et al.(2004) yield macro econometric equations that describe the response of observable economic variables (e.g., GDP growth) to terrorist incidents. We use these equations to determine estimates for relevant (unobservable) structural and policy variables impacted by terrorist incidents, using a CGE model of the U.S. This allows us to: (i) compare values for these shifts with input assumptions in earlier ex-ante CGE studies; and (ii) discuss how future ex-ante studies can be informed by our analysis.

Title: Economic Consequences of Terrorism and Natural Disasters: the Computable General Equilibrium Approach
Speaker: Peter B. Dixon
Date/Time: December 07, 2015 – 12:00
Location: RGL 100
Abstract: Peter Dixon’s presentation will start with a brief comparison of Input-Output and CGE modeling. This will be followed by a description of USAGE and USAGE-TERM. USAGE is a detailed national CGE model of the United States developed at the Centre of Policy Studies (CoPS), Victoria University, with support from the U.S. International Trade Commission and other Federal government agencies. USAGE-TERM is a multi-region version of USAGE developed at CoPS with support from CREATE. The third part of the presentation will be an illustrative application of USAGE-TERM demonstrating the relevance of the model in terrorism analysis. The final part will focus on how the modeling capacity of USAGE-TERM can be made available in a timely fashion to decision makers. The presentation will draw on the chapter with the same name authored by Dixon, Rimmer, Wittwer, Rose and Heatwole that will appear in a book edited by Abbas, von Winterfeldt and Tambe to be published by Cambridge University Press.
Bio: Professor Dixon is known for his work in computable general equilibrium modelling. Together with colleagues at the IMPACT Project and the Centre of Policy Studies, he created the ORANI model and its dynamic successor, MONASH.

Title: Asymmetric Impact of Competitive and Cooperative Environments on Decisions Involving Ambiguity
Speaker: Sule Guney
Date/Time: August 05, 2015 – 14:00
Location: RTH 306
Ambiguity aversion refers to a pattern of preferences favoring options with known winning probabilities (i.e. risky) over those with unknown winning probabilities (i.e. ambiguous), even though normative theories imply indifference. In a couple of studies, we aimed to explore how different strategic environments influence people’s beliefs about winning probabilities and hence their decisions under ambiguity. To do so, we changed the structure of the classic Ellsberg task into a two-player interactive game where the decision-making environment was explicitly made Cooperative (i.e., players’ financial interests were aligned), Competitive (players’ financial interests were opposite), or Non-Competitive (players’ financial interests were independent). In the study, two players were presented with a risky box (50 black and 50 yellow balls), and an ambiguous box (100 black and yellows balls in an unknown proportion); and asked to bet on a color to be drawn from their chosen box. To make the Ellsberg task interactive, one of the players was allowed to arrange the ambiguous box before the box/color choice stage, even though the exact proportion of colored balls remained unknown to both players. The highest level of ambiguity aversion was obtained in the Competitive condition, and the lowest in the Cooperative condition, with the Non-Competitive condition in between. Also, ambiguity attitudes were sensitive to who was in charge of box arrangement in the Competitive condition, but not in the Cooperative condition. Overall our findings indicate that the perceived competitiveness and cooperativeness of the decision-making environment alter attitudes toward ambiguity in opposing directions.

Using her expertise in behavioral and experimental techniques in the area of decision-making, she is currently working on various projects at CREATE, and studying decisions from a decision-analytic perspective, both in terrorism and non-terrorism contexts.
Title: Implementing High-Powered Contracts to Motivate Intertemporal Effort Supply
Speaker: Leon Yang Zhu
Date/Time: July 01, 2015 – 14:00
Location: RTH 306
We characterize the optimal contract between a principal and a risk-neutral, wealth-constrained agent when an adverse selection problem follows a moral hazard problem. The optimal contract in this setting often is more steeply sloped for the largest output levels than is the optimal contract in either the standard moral hazard setting or the standard adverse selection setting. The large incremental rewards for exceptional performance motivate the agent to deliver substantial effort both before and after he acquires privileged information about the production environment.

Title: Location Privacy Preservation in Mobile Networks
Speaker: Miao Pan
Date/Time: June 24, 2015 – 15:00
Location: EEB 248
With over 770 million GPS-enabled smartphones, location Based Service (LBS) has begun to permeate the entire mobile space. Although LBS greatly benefits the daily life of mobile device users, it has introduced significant threats to privacy. In an LBS system, even under the protection of pseudonyms, users may become victims of inference attacks, where an adversary reveals a user’s real identity and complete moving trajectory with the aid of side information, e.g., accidental identity disclosure through personal encounters. To enhance privacy protection for LBS users, in this talk, I will present a centralized location privacy preservation scheme and a distributed approach for achieving k-anonymity, respectively. For the centralized scheme, a new metric to quantify the system's resilience against inferential attack is proposed and multiple mix-zone placement is introduced to tackle this problem. In the case that there is no trusted central authority, we will include extra fake location information associated with different pseudonyms, known as dummy users, and study the behaviors of self-interested users in terms of generating dummy users from a game-theoretic perspective. We model the distributed dummy user generation as Bayesian games in both static and timing-aware contexts, analyze the existence and properties of the Bayesian Nash Equilibria for both models, and propose a strategy selection algorithm to help users achieve optimized payoffs. I will also briefly discuss my most recent work on cybersecurity, cognitive radio networks and cyber-physical systems.

Title: Correlation Between Anomalies and Theories of Mental Accounting
Speaker: Manel Baucells
Date/Time: June 17, 2015 – 14:00
Location: RTH 306
Several consumer choice models account for anomalies in consumption-payment decisions. We consider four such models, including Prelec and Loewenstein 1998 double-entry model and Koszegi and Rabin 2006 reference dependent model. We observe that these models make distinct predictions regarding how different anomalies ought to be related or unrelated. In a controlled experiment we elicit the participant's tendency towards five anomalies, namely, the sunk-cost effect, the reluctance to trade, the flat-rate bias, the preference for pre-pay, and the preference to be post-paid. The observed correlation between anomalies across individuals is consistent with the prediction of Baucells and Hwang 2014 model and, to a large extent, with that of Prelec and Loewenstein 1998. The evidence is partially consistent with Thaler 1985, and we find little support for Koszegi and Rabin 2006. The results suggest that the speed of adaptation of reference prices to current price information is a key explanatory factor.

Title: From Controversy to Consensus: Decommissioning California's offshore oil platforms
Speaker: Max Henrion
Date/Time: April 14, 2015 – 14:00
Location: PHE 333
Like many issues of energy and environment, there was much controversy about how to decommission California's 27 offshore oil platforms. Complete removal was required by the original leases, but would cost over a billion dollars, and destroy the rich marine ecosystems that have grown up around these platforms. A decision analysis provided stakeholders with insights that helped form consensus for a “rigs to reefs” option — removing the platform tops and retaining the supports as an artificial reef. An enabling law was passed by the California Statehouse with near unanimity. This talk illustrates the practical value of:
- Using decision trees and influence diagrams to simplify the model
- Examining different points of view with a multi-attribute decision model
- Enabling stakeholders to explore the effects of changing assumptions and preferences with interactive decision software
- Analyzing sensitivities to uncertainties and preferences
- Creatively designing better decision options
- Summarizing key insights on a single page
This project won the 2014 Decision Analysis Practice Award from the Society of Decision Professionals and INFORMS Decision Analysis Society.

Title: Cognitive and Motivational Biases in Decision and Risk Analysis
Speaker: Gilberto Montibeller/Detlof von Winterfeldt
Date/Time: March 25, 2015 – 14:00
Location: RTH 306
Behavioral decision research has demonstrated that judgments and decisions of ordinary people and experts are subject to numerous biases. Decision and risk analysis were designed to improve judgments and decisions and to overcome many of these biases. However, when eliciting model components and parameters from decision-makers or experts, analysts often face the very biases they are trying to help overcome. When these inputs are biased they can seriously reduce the quality of the model and resulting analysis. Some of these biases are due to faulty cognitive processes; some are due to motivations for preferred analysis outcomes. In this talk we identify the cognitive and motivational biases that are relevant for decision and risk analysis, because they can distort analysis inputs and are difficult to correct. We also review and provide guidance about the existing debiasing techniques to overcome these biases. In addition, we describe some biases that are less relevant, because they can be corrected by using logic or decomposing the elicitation task. We conclude the talk with an agenda for future research on this topic.
Bio: Dr. Gilberto Montibeller is a Tenured Lecturer in Management Science, in the Department of Management, at the London School of Economics, and Course Director of its MSc in Management Science.

Title: Cognitive Constraints on Valuing Annuities
Speaker: Arie Kapteyn
Date/Time: February 04, 2015 – 13:45
Location: RTH 306
This paper documents consumers' difficulty valuing life annuities (paper attached). We show that the prices at which people are willing to buy annuities are substantially below the prices at which they are willing to sell them, a finding we show is not attributable to an endowment effect. We also find that buy values are negatively correlated with sell values and that the sell-buy valuation spread is negatively correlated with cognition; the spread is larger for those with less education, weaker numerical abilities, and lower levels of financial literacy. Our evidence contributes to the emerging literature on heterogeneity in financial decision-making abilities.
Bio: Arie Kapteyn, Ph.D. is a Professor of Economics and the Executive Director of the Dornsife College of Letters Arts and Sciences Center for Economic and Social Research (CESR) at the University of Southern California.

Title: System Design under Uncertainty: Scheduling and Incentive Policies
Speaker: Amy Ward
Date/Time: January 28, 2015 – 14:00
Location: RTH 306
We present several system design questions, and discuss their analysis. Our purpose is to understand which types of models are most relevant for the applications of interest to CREATE. We begin with a more classical network control problem, in which we must decide how to schedule jobs for processing at different stations in a network. Although there is a broad literature on such problems, there has been less focus on networks in which there is both sequential and parallel processing of jobs, and this is where our interest lies. Our next problem considers how to control congestion when processing resources are people, instead of machines, as is the case in many service systems. The difference is that machines work at fixed rates (as is assumed in traditional queueing theory) whereas people may work faster or slower, depending on their incentives. We want to understand how incentives influence system performance, and we do this by looking at a queueing game. We end by very briefly summarizing some current research thoughts on emergency department design, and on capacity sizing when there is demand uncertainty.
