Taking a holiday trip is a common couple-based leisure activity in which both partners tend to be actively involved. This paper studies the intra-household bargaining for the choice of a vacation destination within couples. We conduct a discrete choice experiment in which we elicit both individual and couple preferences for different hypothetical travel portfolios in a two-stage experimental design. The couple choices are modelled as a function of males' and females' individual preferences, allowing for different bargaining weights for each characteristic of the holiday trip. Therefore, we assess partners’ bargaining power (influence) in the couple choices conditional on individual preferences. We find that although males have a more influential role overall, there seems to be a gender specialization in that females decide on the type of accommodation and males focus on the trip cost.

度假旅行是一种常见的以情侣为基础的休闲活动,伴侣双方都倾向于积极参与其中。本文研究了夫妻双方在度假目的地选择方面的家庭内部谈判。我们进行了一个离散选择实验,在两阶段的实验设计中,我们引出了个人和夫妇对不同假设旅行组合的偏好。夫妇的选择是根据男性和女性的个人偏好进行建模的,从而为度假旅行的每一个特征提供不同的讨价还价权重。因此,我们根据个人偏好来评估伴侣在夫妻选择中的议价能力(影响力)。我们发现,尽管男性在总体上发挥着更大的影响力,但似乎存在性别专业化,女性决定住宿类型,男性关注旅行成本。

Individual migration mobilities over the life course have not been well understood in existing studies, and therefore ways to represent the underlying intertemporal dynamics and heterogeneities have remained unclear. To fill this research gap, this study investigates the domestic migration of people residing in the Capital Area of Japan, which has suffered from various issues caused by the over-concentration of population for several decades. Using a web-based questionnaire survey, workers aged 20–49 living in the Capital Area were requested to recall their five latest migration experiences (i.e., migration biography). A life-course intertemporal discrete choice model with cross-sectional and longitudinal heterogeneities was developed to represent individual migration destination biographies, by introducing quasi-hyperbolic utility and drawing on time preference theory. It was found that a considerable proportion of working people in the Capital Area (especially Tokyo) are from other regions of Japan. In the modeling analysis, the temporally-changing, intertwined and heterogeneous roles of place attachment, motives and altruism in migration decisions over the life course are empirically confirmed. Nonlinear influences of past, present and future utilities are further revealed, where the past utility grows more influential, and the importance of future utility diminishes over time. Policy implications of the derived findings for the development of megacities and local cities are discussed.

在现有的研究中,个体在整个生命过程中的迁移流动性还没有得到很好的理解,因此,如何表示潜在的跨期动态和异质性仍然不清楚。为了填补这一研究空白,本研究调查了居住在日本首都地区的人口的国内迁移,几十年来,由于人口过度集中,日本首都地区一直面临着各种问题。通过一项基于网络的问卷调查,要求居住在首都地区的20-49岁的工人回忆他们最近的五次移民经历(即移民传记)。通过引入拟双曲型效用并借鉴时间偏好理论,建立了一个具有横截面和纵向异质性的生命历程跨期离散选择模型,以代表个人的移民目的地传记。研究发现,首都地区(尤其是东京)有相当一部分劳动人口来自日本其他地区。在建模分析中,从经验上证实了地方依恋、动机和利他主义在生命过程中移民决策中的时间变化、交织和异质作用。进一步揭示了过去、现在和未来效用的非线性影响,其中过去效用的影响力越来越大,而未来效用的重要性随着时间的推移而减弱。讨论了所得结果对特大城市和地方城市发展的政策影响。

Cost vector effects in discrete choice experiments with positive status quo cost 具有正现状成本的离散选择实验中的成本向量效应

An important component of the design phase of a discrete choice experiment (DCE) is formulating the cost vector, which specifies the costs of the alternatives and enables the calculation of marginal willingness to pay (WTP) estimates. If the cost vector affects choice behaviour, welfare estimates may depend on the choice of the cost vector, which leads to problems with the validity and reliability of DCE results. We employ a split-sample design to examine cost vector effects on choice behaviour and WTP estimates. Our data come from a DCE on agri-environmental policies to a nationally representative sample in Finland. We provide additional insights compared to previous research by including four cost vectors with otherwise identical surveys and experimental designs and a positive cost for the status quo alternative, with cost levels for policy alternatives both below and above the status quo cost. We obtain some evidence that the cost vector affects choice behaviour, as the proportion of status quo choices is larger with higher cost vectors. Both absolute and relative cost levels matter for choices. The marginal WTP estimates are highest in the sub-sample with the largest range cost vector that has cost levels both below and above the status quo cost. We suggest more careful pre-testing of the cost levels compared to current practices to determine a plausible range of cost levels to produce valid welfare estimates.

离散选择实验(DCE)设计阶段的一个重要组成部分是制定成本向量,该向量指定了备选方案的成本,并能够计算边际支付意愿(WTP)估计值。如果成本向量影响选择行为,福利估计可能取决于成本向量的选择,这会导致DCE结果的有效性和可靠性问题。我们采用分样本设计来检验成本向量对选择行为和WTP估计的影响。我们的数据来自DCE对芬兰全国代表性样本的农业环境政策。与之前的研究相比,我们提供了更多的见解,包括四个具有相同调查和实验设计的成本向量,以及现状替代方案的正成本,政策替代方案的成本水平低于和高于现状成本。我们获得了一些证据,证明成本向量会影响选择行为,因为成本向量越高,现状选择的比例越大。绝对和相对成本水平对选择都很重要。边际WTP估计值在具有最大范围成本向量的子样本中最高,该子样本的成本水平低于或高于现状成本。与目前的做法相比,我们建议对成本水平进行更仔细的预测试,以确定合理的成本水平范围,从而得出有效的福利估计。

We propose three procedures based on association rules (AR) learning and random forests (RF) to support the specification of a portfolio choice model applied in data from complex choice experiment data, specifically a Participatory Value Evaluation (PVE) choice experiment. In a PVE choice experiment, respondents choose a combination of alternatives, subject to a resource constraint. We combine a methodological-iterative (MI) procedure with AR learning and RF models to support the specification of parameters of a portfolio choice model. Additionally, we use RF model predictions to contrast the validity of the behavioural assumptions of different specifications of the portfolio choice model. We use data of a PVE choice experiment conducted to elicit the preferences of Dutch citizens for lifting COVID-19 measures. Our results show model fit and interpretation improvements in the portfolio choice model, compared with conventional model specifications. Additionally, we provide guidelines on the use of outcomes from AR learning and RF models from a choice modelling perspective.

我们提出了三个基于关联规则(AR)学习和随机森林(RF)的程序,以支持在复杂选择实验数据中应用的投资组合选择模型的规范,特别是参与式价值评估(PVE)选择实验。在PVE选择实验中,受试者在资源限制的情况下选择多种选择。我们将方法迭代(MI)过程与AR学习和RF模型相结合,以支持投资组合选择模型的参数规范。此外,我们使用RF模型预测来对比投资组合选择模型的不同规范的行为假设的有效性。我们使用PVE选择实验的数据来引出荷兰公民对解除新冠肺炎措施的偏好。我们的结果表明,与传统的模型规范相比,投资组合选择模型的模型拟合和解释有所改进。此外,我们从选择建模的角度提供了AR学习和RF模型结果的使用指南。

This article investigates the usage of a general model-based recursive partitioning algorithm to model preference heterogeneity. We use the algorithm to grow a decision tree based on statistical tests of the stability of individuals’ preference parameters. In particular, we used a Mixed Logit (MIXL) model with alternative-specific attributes at the end leaves of the tree while using individual characteristics as partition variables. This configuration allows us to search for instabilities of the taste parameters across individuals’ characteristics. We conduct a simulation study to investigate the algorithm’s ability to recover different data generating processes with structural breaks in the taste parameters. The results show that the algorithm can correctly recover diverse tree-like data generating processes. Additionally, we applied the algorithm to stated choice data of the preferences for the environmental impact of (hypothetical) energy generation plans in Chile. The results show that the model-based decision tree fits the data better than MIXL in terms of information criteria. Moreover, we show that the derived tree structure depends on the assumptions on the parameters’ distributions. Additionally, we compare the model-based decision tree model with Latent Class (LC) models with and without within-class heterogeneity. Finally, we show that the recursive partitioning algorithm can inform the selection of variables to be included in the LC allocation models.

本文研究了一种通用的基于模型的递归划分算法在偏好异质性建模中的应用。我们使用该算法在对个人偏好参数稳定性的统计测试的基础上生长决策树。特别是,我们使用了一个混合Logit(MIXL)模型,该模型在树的尾叶处具有可选的特定属性,同时使用单个特征作为分区变量。这种配置允许我们在个体特征之间搜索味觉参数的不稳定性。我们进行了一项模拟研究,以研究该算法在味觉参数出现结构断裂的情况下恢复不同数据生成过程的能力。结果表明,该算法能够正确地恢复不同的树状数据生成过程。此外,我们将该算法应用于智利(假设)能源发电计划的环境影响偏好的声明选择数据。结果表明,在信息准则方面,基于模型的决策树比MIXL更适合数据。此外,我们还证明了导出的树结构取决于对参数分布的假设。此外,我们将基于模型的决策树模型与具有和不具有类内异构性的潜在类(LC)模型进行了比较。最后,我们证明了递归划分算法可以通知要包括在LC分配模型中的变量的选择。

Multiple discrete choice and quantity with order statistic marginal utilities 具有订单统计边际效用的多重离散选择与数量

This paper presents a random utility maximization model for individuals selecting discrete quantities from a set of n alternatives. Multiple alternatives with positive quantities may be selected. Diminishing marginal utility to quantity of each alternative is modeled via order statistics of independent Gumbel random variables. The model is parsimonious and tractable, admitting closed-form expressions for choice probabilities. As such, the model is amenable to maximum likelihood estimation of structural parameters from observed choices.

Probability functions recover binary logit probabilities under binary choice and a maximum quantity of one unit, and probability is monotonic in the quantity of each alternative. The monotonic property likely restricts the application of the model to a narrow range of settings. The property is a manifestation of a recursive relationship among Gumbel order statistic probabilities. This relationship and related properties may lead to new models for capturing important complexities in a tractable manner.

本文提出了一个随机效用最大化模型,用于个体从一组n个备选方案中选择离散量。可以选择多个具有正数量的备选方案。边际效用对每个备选方案数量的递减是通过独立Gumbel随机变量的顺序统计建模的。该模型简洁易处理,允许选择概率的闭式表达式。因此,该模型适用于根据观察到的选择对结构参数进行最大似然估计。概率函数在二元选择和一个单位的最大数量下恢复二元logit概率,并且概率在每个备选的数量上是单调的。单调特性可能会将模型的应用限制在较窄的设置范围内。该性质是Gumbel阶统计概率之间递归关系的表现。这种关系和相关属性可能会导致以可处理的方式捕捉重要复杂性的新模型。

Endogeneity and correlated alternatives are major concerns to be addressed in travel behavior analysis. However, these issues have rarely been dealt with simultaneously in advanced discrete choice models. This study proposes a multinomial probit model that incorporates the instrumental variable method, namely, a fully parametric instrumental variable model for a multinomial choice. The proposed model has the following three characteristics: (1) it allows binary and/or continuous endogenous variables; (2) it allows any number of instrumental variables in each alternative; and (3) it allows positive and/or negative correlations between any choice alternatives. For parameter estimation, we also propose a Bayesian Markov chain Monte Carlo algorithm that can be accommodated in more extended model structures. The simulation study demonstrates that the proposed model addresses endogeneity while allowing correlations between the choice alternatives. Meanwhile, the simulation also implies that the users need to pay attention to the setting of the prior distribution when an endogenous variable of interest is binary, even if the sample size is moderate. The proposed model will be a useful tool in disciplines in which both endogeneity and correlations between choice alternatives are major concerns.

内在性和相关的替代方案是旅行行为分析中需要解决的主要问题。然而,在高级离散选择模型中很少同时处理这些问题。本研究提出了一个包含工具变量法的多项式多项式概率模型,即多项式选择的全参数工具变量模型。该模型具有以下三个特点:(1)允许二元和/或连续的内生变量;(2) 它允许在每个备选方案中使用任意数量的工具变量;以及(3)它允许任何选择备选方案之间的正相关性和/或负相关性。对于参数估计,我们还提出了一种贝叶斯马尔可夫链蒙特卡罗算法,该算法可以适应更多扩展的模型结构。模拟研究表明,所提出的模型解决了内生性问题,同时允许选择方案之间的相关性。同时,模拟还表明,当感兴趣的内生变量是二元的时,即使样本量适中,用户也需要注意先验分布的设置。所提出的模型将是一个有用的工具,在这些学科中,内生性和选择方案之间的相关性都是主要关注的问题。

Discrete mixture (DM) models recognize the presence of heterogeneity across individuals in a given population. In the context of a public land use discrete choice experiment, we use DM models to allow for respondent behavior to probabilistically mix over multiple competing process heuristics. We pairwise combine the Random Utility Model (RUM), Contextual Concavity Model (CCM), and Random Regret Minimization (RRM) heuristic into three DM models, in which the probability of an individual adhering to a particular heuristic is modeled as a function of sociodemographic characteristics. We present a comprehensive Bayesian analysis for which we explicitly describe prior selection, inferential procedures, and model comparison metrics. We use a fully Bayesian information criterion to rank the models. We find evidence that responses are best modeled using random regret. After accounting for preference heterogeneity, the DM models estimate two latent groups of decision makers. For the DM models, we develop a novel algorithm to calculate posterior-weighted willingness to pay estimates for improvements in different public park amenities in Polk County, Iowa.

离散混合(DM)模型可以识别给定人群中个体之间的异质性。在公共土地使用离散选择实验的背景下,我们使用DM模型来允许受访者的行为在多个竞争过程启发式中进行概率混合。我们将随机效用模型(RUM)、上下文凹形模型(CCM)和随机回归最小化(RRM)启发式算法成对组合成三个DM模型,其中个体遵守特定启发式算法的概率被建模为社会人口统计特征的函数。我们提出了一个全面的贝叶斯分析,明确描述了先验选择、推理过程和模型比较指标。我们使用完全贝叶斯信息标准来对模型进行排序。我们发现有证据表明,反应最好使用随机后悔来建模。在考虑偏好异质性后,DM模型估计了两组潜在的决策者。对于DM模型,我们开发了一种新的算法来计算爱荷华州波尔克县不同公共公园设施改善的后验加权支付意愿估计。

Applications of discrete choice models in personalization are becoming increasingly popular among researchers and practitioners. However, in such systems, when users are presented with successive menus (or choice situations), the alternatives and attributes in each menu depend on the choices made by the user in the previous menus. This gives rise to endogeneity which can result in inconsistent estimates. Our companion paper, Danaf et al. (2020), showed that the estimates are only consistent when the entire choice history of each user is included in estimation. However, this might not be feasible because of computational constraints or data availability. In this paper, we present a control-function (CF) correction for the cases where the choice history cannot be included in estimation. Our method uses the attributes of non-personalized attributes as instruments, and applies the CF correction by including interactions between the explanatory variables and the first stage residuals. Estimation can be done either sequentially or simultaneously, however, the latter is more efficient (if the model reflects the true data generating process). This method is able to recover the population means of the distributed coefficients, especially with a long choice history. The variances are underestimated, because part of the inter-consumer variability is explained by the residuals, which are included in the systematic utility. However, the population variances can be computed from the estimation results. The modified utility equations (which include the residuals) can be used in forecasting and model application, and provide superior fit and predictions.

离散选择模型在个性化中的应用在研究人员和从业者中越来越受欢迎。然而,在这样的系统中,当向用户呈现连续的菜单(或选择情况)时,每个菜单中的选项和属性取决于用户在先前菜单中做出的选择。这就产生了内生性,可能导致不一致的估计。我们的配套论文Danaf等人(2020)表明,只有当每个用户的整个选择历史都包含在估计中时,估计才是一致的。然而,由于计算限制或数据可用性的原因,这可能不可行。在本文中,我们提出了一种控制函数(CF)校正,用于估计中不能包括选择历史的情况。我们的方法使用非个性化属性的属性作为工具,并通过包括解释变量和第一阶段残差之间的相互作用来应用CF校正。估计可以按顺序进行,也可以同时进行,但后者更有效(如果模型反映了真实的数据生成过程)。该方法能够恢复分布系数的总体均值,特别是在具有较长选择历史的情况下。方差被低估了,因为消费者之间的部分可变性是由残差解释的,残差包含在系统效用中。然而,可以根据估计结果来计算总体方差。修正后的效用方程(包括残差)可用于预测和模型应用,并提供优越的拟合和预测。

Case 1 best–worst scaling (BWS1) has been used in a wide variety of research fields. BWS1 is attractive, relative to discrete choice experiments, because individual’s preferences for items can be easily measured. Despite the relative ease of implementation, BWS1 analysis still requires the use of software packages. When used in conjunction with other packages, the new and revised functions in the package support.BWS allow BWS1 analysis to be conducted using either the counting approach or the modeling approach. Additionally, a new function that simulates responses to BWS1 questions allows discipline specific BWS1 examples to be created for teaching purposes. To make it easier for novice users to implement BWS1 analysis with R, the package RcmdrPlugin.BWS1, that integrates with R Commander has been developed. A free web tutorial for BWS1 in R has also been developed. This paper explains the features of the latest version of support.BWS, along with the new package RcmdrPlugin.BWS1, and illustrates how these packages work.

案例1最佳-最差缩放(BWS1)已被广泛应用于各种研究领域。相对于离散选择实验,BWS1是有吸引力的,因为个人对物品的偏好可以很容易地测量。尽管实现相对容易,BWS1分析仍然需要使用软件包。当与其他软件包一起使用时,软件包中的新功能和修订功能提供支持。BWS允许使用计数方法或建模方法进行BWS1分析。此外,一个模拟对BWS1问题的回答的新功能允许为教学目的创建特定学科的BWS1示例。为了让新手用户更容易使用R实现BWS1分析,开发了与R Commander集成的包RcmdrPlugin.BWS1。还为R中的BWS1开发了一个免费的网络教程。本文介绍了最新版本支持的功能。BWS,以及新的包RcmdrPlugin.BWS1,并说明了这些包是如何工作的。
