“…For instance, due to the exclusion of non‐considered alternatives, variation in the design matrix was drastically reduced, which leads to increased confidence intervals for parameter estimates. Moreover, commonly used goodness‐of‐fit statistics like McFadden's pseudo R 2 (McFadden ) will tend to be biased downwards as ‘a fully parameterized model almost always will be better at predicting that options outside the consideration sets have lower probabilities of being chosen relative to options in consideration sets’ (Carson & Louviere ).…”

For a long time the question of to what extent party choice in the European Parliament (EP) elections is primarily dependent on voters’ orientations towards the European Union (EU) or just a mere reflection of orientations towards issues and actors in national politics has been debated. By combining insights from individual‐level models of party choice in second‐order elections with theories of sequential decision making this article investigates if, how and at what stages in the decision process attitudes to European integration matters for party choice. In line with previous work on first and second decision rule criteria in EP elections, this article develops and tests hypotheses about how voters’ orientations work at different stages of the voter decision process. The findings, based on Swedish data from a probability‐based three‐wave Internet campaign panel, indicate that many voters are in fact considering more than one party to vote for in the beginning of the election campaign. As expected, left‐right orientations function as a main decision rule with respect to which parties voters even consider voting for, while proximity on the European integration dimension mainly matters as a second decision rule in the final stage of the decision process. Using a sequential model with consideration and choice stages, the article reveals a much larger complimentary effect of EU proximity on party choice than has generally been found in previous research. This serves as a distinct contribution to the emerging research field of individual party choice in second‐order elections.

“…Because of the potential problems identified by Horowitz and Louviere () and Carson and Louviere () we do not advise conditioning on these consideration sets in estimating models of recommendations. Instead, we follow the argument of Horowitz and Louviere () that a consideration set is simply a reflection of the underlying preferences.…”

“…That approach would involve modelling our recommendations data using standard choice modelling techniques assuming that the particular products initially chosen by the GP form the consideration sets; see for example Roberts and Lattin (). Carson and Louviere () are warranted in their criticism of such an approach. There is a real threat to econometric analysis because it was the doctors who indicated which products should form the choice set and hence the assumption of exogeneity required by standard choice modelling is potentially problematic.…”

Consideration Sets and Their Role in Modelling Doctor Recommendations About Contraceptives

et al. 2015

View full text Add to dashboard Cite

Decisions about prescribed contraception are typically the result of a consultation between a woman and her doctor. In order to better understand contraceptive choice within this environment, stated preference methods are utilized to ask doctors about what contraceptive options they would discuss with different types of women. The role of doctors is to confine their discussion to a subset of products that best match their patient. This subset of options forms the consideration set from which the ultimate recommendation is made. Given the existence of consideration sets we address the issue of how to model appropriately the ultimate recommendations. The estimated models enable us to characterize doctor recommendations and how they vary with patient attributes and to highlight where recommendations are clear and when they are uncertain. The results also indicate systematic variation in recommendations across different types of doctors, and in particular we observe that some doctors are reluctant to embrace new products and instead recommend those that are more familiar. Such effects are one possible explanation for the relatively low uptake of more cost effective longer acting reversible contraceptives and indicate that further education and training of doctors may be warranted.

“…2 To accommodate the size of the destination space and to account for heterogeneous individuals, I apply a conditional logit model for heterogeneous agents. This model might be susceptible to varying definitions of the underlying choice set (Hicks and Strand 2000;Carson and Louviere 2014), and thus to the level of available information on the choice process itself. Therefore, one aspect of my empirical analysis is to integrate information on considered alternatives during the university application process.…”

How Personality Shapes Study Location Choices

In this paper I investigate undergraduate students' discrete location choices in presence of a plethora of potential destinations and psychic costs. I demonstrate how enrolment into institutions of tertiary education is influenced by personality and social preferences. More importantly, these individual traits are found to affect the valuation of location-specific conditions in alternative study locations. Eventually, the relevance of location attributes, such as urban or labour market characteristics, varies substantially with respect to distance and individuals' personality. This has direct implications for student recruitment, since prospective students display distinct geographic sorting patterns along these traits: students featuring higher levels of patience integrate post-graduation opportunities into their decision-making. As a consequence, institutions in economically less prosperous regions might attract a specific subset of the overall student population, which might also have repercussions on student performance.
