Advances in computation,statistical methods,and testing of discrete choice models

This paper gives a brief overview of recent developments in computation, estimation, and statistical testing of choice models, with marketing applications. Topics include statistical models for discrete panel data with heterogeneous decision-makers, simulation methods for estimation of high-dimension multinomial probit models, specification tests for model structure and for brand and purchase clustering, and innovations in numerical analysis for estimation and forecasting. In collaboration with Denis Bolduc, David Bunch, Michael Keane, Don Kridel, and Steve Stern.     

Agricultural sustainability of small-scale farms in Lacluta,Timor Leste

Despite the trend of dwindling productivity, tribal people of the Chittagong Hill Tracts (CHT) still practise shifting cultivation as a dominant hill farming system to support their livelihood. Drawing on an empirical study in Khagrachari district of the CHT, this research examined how far the production from present shifting cultivation supports the tribal people's livelihood and what alternative livelihood strategies they have adopted for subsistence by using data on input/output and income/expenditures, and analysing current government policies. The findings showed that productivity declined markedly, yields were almost equal to input values and farmers experienced food shortages for at least two to six months in a year. To make a living, farmers have adopted new occupations such as wage labour, animal husbandry, cultivation of annual monocrops and extraction and selling of forest products. Policy analysis indicates that previous policies were unable to reduce shifting cultivation intensity or improve tribal people's livelihoods or the region's forest resources. Reorientation of government policies, easy access to institutional support and the active participation of local people in development intervention are of the utmost importance in order to find alternative land uses for sustainable hill farming, to improve the farmer's living standards and to conserve forests and protect watersheds.     

“Reading” whiteness in consumer research

The concept of whiteness has been widely debated in the social sciences and humanities but has rarely surfaced as a theme in consumer research. This paper introduces whiteness theory as an additional theoretical perspective available to consumer researchers to add to those that are well established. The empirical section of the paper comprises a textual analysis of articles published in the Journal of Consumer Research from 1974–2004. The findings suggest that consumer research is dominated by “white faces” and “white spaces,” resulting in many investigators consciously or unconsciously performing whiteness. The ways whiteness can be re‐articulated to stimulate more interest within consumer research are discussed.     

Pinstripes and Breast Pumps: Navigating the Tenure-Motherhood-Track

Guided by the competing sociological concepts of the ideal worker and intensive mothering, and building on previous research on women in academia, the intent of this paper is to critically examine the transition to motherhood while being a junior faculty member in a tenure-track position. Issues related to the pregnant body and how it alters scholarly identity through the internal gaze as well as the subjectivities from the institution are examined. The significance of leisure-based friendships for social support, personal health, well-being, and identity reconstruction and expression are emphasized. Despite the documented difficulties and negative outcomes, I argue that in many ways being a parent and a scholar are complementary and can strengthen the very creation of knowledge.     

The Role of Habit,Childhood Consumption,Familiarity, and Attitudes Across Seafood Consumption Segments in Australia

Australian consumers hold very favorable attitudes toward seafood, with key drivers to consumption being taste, convenience, diet variety, and health benefits. Nevertheless, despite these positive attitudes, seafood consumption remains below many other countries. In this article, we investigate the influence of habit including regular childhood consumption, familiarity with seafood, and attitudes toward seafood on seafood consumption and consumption occasions. Habit and lack of familiarity with seafood were found to lead to lower levels of seafood consumption, whereas positive attitudes toward seafood were associated with more regular seafood consumption. People who consumed seafood on a regular basis as a child were more likely to be more familiar with seafood and be in the habit of consuming seafood in adulthood. Patterns of childhood consumption occasions were found to be associated with adult consumption occasions. Based on these findings, we discuss possible strategies and behavioral interventions for further investigation, which are grounded in habit theory and are aimed at changing seafood eating habits, increasing childhood consumption, and reducing the lack of familiarity with seafood.     

Land Market Interactions between Heterogeneous Agents in a Heterogeneous Landscape—Tracing the Macro-Scale Effects of Individual Trade-Offs between Environmental Amenities and Disamenities

Heterogeneity in both the spatial environment and economic agents is a crucial driver of land market dynamics. We present an agent‐based land market model where land from agriculture use is transferred into urban. The model combines the microeconomic demand, supply, and bidding foundations of spatial economics models with the spatial heterogeneity of spatial econometric models in a single methodological platform. Heterogeneous agents exchange heterogeneous spatial goods via simulated bilateral market interactions. We model a coastal city where both coastal amenities and flooding or erosion disamenities drive land market outcomes, facilitating separate analysis of the effects of each driver on land rents and land development patterns. We also analyze the implications of homogeneous versus heterogeneous but unbiased flood risk perceptions. Since buyers with low risk perceptions drive market outcomes, spatial development under heterogeneous risk perceptions differs qualitatively, with more expansion into risky areas. Our results highlight the shortcomings of policy models based on representative agent assumptions and the importance of including agent‐level data in empirical modeling. L'hétérogénéité de l'environnement spatial et des agents économiques constitue un élément moteur crucial de la dynamique du marché foncier. Nous présentons un modèle multi‐agent du marché foncier dans lequel des terres agricoles ont été transférées pour des fins urbaines. Le modèle combine les fondements microéconomiques de la demande, de l'offre et des enchères de modèles de l'économie spatiale avec l'hétérogénéité spatiale des modèles de l'économétrie spatiale dans une plateforme méthodologique unique. Les agents hétérogènes échangent des biens hétérogènes par le biais du jeu des forces du marché bilatéral simulé. Nous avons modélisé une ville côtière où les agréments côtiers et les désagréments causés par les inondations ou l'érosion influent sur le marché foncier, facilitant l'analyse individuelle des effets de chaque élément moteur sur les loyers fonciers et les modèles d'aménagement de terrain. Nous avons également analysé les répercussions des perceptions homogènes et hétérogènes mais non biaisées à l'égard du risque d'inondation. Étant donné que les acquéreurs qui ont de faibles perceptions du risque motivent les effets du marché, le développement spatial selon des perceptions hétérogènes à l'égard du risque varie qualitativement, avec plus d'expansion dans les zones à risque. Nos résultats ont mis en lumière les lacunes des modèles de politiques fondés sur les hypothèses d'un agent représentatif et l'importance d'inclure des données sur l'hétérogénéité des agents dans la modélisation empirique.
