On Monday the 3rd of April Dr Habtamu Kassahun presented at the 2017 International Choice Modelling Conference in Cape Town, South Africa. 

Dr Habtamu Kassahun, from the Institute for Choice, travelled to and presented at the International Choice Modelling Conference in Cape Town, South Africa. The conference ran from the 3rd - 5th of April. The conference brought together leading researchers and practitioners from across the world and across different areas of study, including but not limited to transport studies, marketing decision making, environmental valuation and health economics.The aim of the conference was to review recent advancements in knowlege and understanding in methodology as well as real world applications of choice models and stated choice and revealed preference survey techniques. 

Presentation Title: 

Making choice set formation practicable through direct elicitation of availability and choice


Misspecification of choice sets is a known major issue in choice model development. Both ignoring and misspecifying choice sets lead to biased parameter and welfare estimates. Modeling latent choice set formation is challenging due to the combinational complexity. The objective for this paper is therefore to propose a tractable Integrated Availability and Choice Model (IACM) that account for choice set formation, even in situations with many alternatives. We circumvent this complexity by considering all alternatives with some probability, which is consistent with standard microeconomics theory. However, we show how to avoid enumeration of latent choice sets to eliminate complexity.

Behavoural Economics (A Very Short Introduction) - Michelle Baddeley

Michelle Baddeley from the Institute of Choice has recently released a new book titled Behavioural Economics which is a part of the Very Short Introductions series. 

The study of behavioral economics is revealing that our lives are not that simple. Instead, our decisions are complicated by our own psychology. Each of us makes mistakes every day. We don't always know what's best for us and, even if we do, we might not have the self-control to deliver on our best intentions. We struggle to stay on diets, to get enough exercise and to manage our money. We misjudge risky situations. We are prone to herding: sometimes peer pressure leads us blindly to copy others around us; other times copying others helps us to learn quickly about new, unfamiliar situations.

This book explains why we make irrational decisions; how we decide quickly; why we make mistakes in risky situations; our tendency to procrastination; and how we are affected by social influences, personality, mood and emotions. The implications of understanding the rationale for our own financial behavior are huge. Behavioral economics could help policy-makers to understand the people behind their policies, enabling them to design more effective policies, while at the same time we could find ourselves assaulted by increasingly savvy marketing. Michelle Baddeley concludes by looking forward, to see what the future of behavioral economics holds for us.

Presentation title: “Towards more representative travel cost modelling: an economic valuation of the NSW protected area network”

Presentation date: Thursday 9th February, 2017

Invited to present at: 61st Australian Agricultural & Resource Economics Society (AARES) Annual Conference, Brisbane, 8-10 February 2017

Abstract: Travel cost modelling has been used to value recreational sites since the 1940s, but typically, studies have relied on data collected through on-site survey at a relatively small number of sites. Our study explores the implications and advantages of shifting towards more representative survey methodologies. We have analysed data from a random stratified phone survey of more than 60,000 households across four states and territories (NSW, QLD, Victoria and the ACT) in which survey respondents were questioned about their recent use of any and all of the 728 protected areas across NSW. We have used novel travel cost modelling techniques, including ordered choice modelling and zero-inflated choice set formation, to estimate consumer surplus and identify key drivers of recreational demand. This methodology confers a range of advantages over traditional analysis techniques, including the capacity to ensure value estimates are robustly and representatively scaled to the broader population, the ability to undertake empirical analysis of the distributional effects, and a means of imputing visitation rates to individual sites across a protected area network – including low visitation sites for which data is usually unavailable. We provide the first revealed-preference estimate of the tourism and recreation value of an entire protected area network and explore implications for strategic development of recreational opportunities within the NSW protected area network.

2017 Choice Modelling Symposium

On the 13th of February, Dr Akshay Vij presented his paper 'Integrated choice and latent variable mobels: looking back and moving forward' at the 2017 Choice Modelling Symposium.  

The description of this talk was as follows:

'Integrated Choice and Latent Variable (ICLV) models are econometric models of individual behavior that attempt explicitly to model the cognitive process underlying the formation of any choice. The ICLV model combines discrete choice models and structural equation models under a single unified framework that recognizes the influence of both observable economic variables and latent psychosocial constructs on behavior.

Though much progress has been made in terms of model development and estimation, concerns remain regarding the value of the framework to practitioners and policy-makers. On one hand, ICLV models appear to be powerful methods with which to enhance existing representations of decision-making. They allow for the proper integration of psychometric data within extant model frameworks and provide statistical tools with which to test complex theories of behavior. On the other, questions have been raised regarding the practical benefits of the framework. Does an ICLV model fit the choice data better than a simpler choice model without latent variables? Can findings from an ICLV model be used for policy analysis in ways that are not already possible using choice models without latent variables?

This talk will systematically evaluate the benefits of the ICLV model framework over a more traditional choice model without latent variables, using a set of criteria based on statistical considerations and relevance to practice and policy. Analytical proofs will be presented that demonstrate the practical value of the framework, and findings from both synthetic and real datasets will be used to corroborate any conclusions. The talk will close by outlining an agenda for future research on the subject.'
