Accommodating spatial correlation across choice alternatives in discrete choice models: an application to modeling residential location choice behavior

This paper presents a modeling methodology capable of accounting for spatial correlation across choice alternatives in discrete choice modeling applications. Many location choice (e.g., residential location, workplace location, destination location) modeling contexts involve choice sets where alternatives are spatially correlated with one another due to unobserved factors. In the presence of such spatial correlation, traditional discrete choice modeling methods that are often based on the assumption of independence among choice alternatives are not appropriate. In this paper, a Generalized Spatially Correlated Logit (GSCL) model that allows one to represent the degree of spatial correlation as a function of a multi-dimensional vector of attributes characterizing each pair of location choice alternatives is formulated and presented. The formulation of the GSCL model allows one to accommodate alternative correlation mechanisms rather than pre-imposing restrictive correlation assumptions on the location choice alternatives. The model is applied to the analysis of residential location choice behavior using a sample of households drawn from the 2000 San Francisco Bay Area Travel Survey (BATS) data set. Model estimation results obtained from the GSCL are compared against those obtained using the standard multinomial logit (MNL) model and the spatially correlated logit (SCL) model where only correlations across neighboring (or adjacent) alternatives are accommodated. Model findings suggest that there is significant spatial correlation across alternatives that do not share a common boundary, and that the GSCL offers the ability to more accurately capture spatial location choice behavior.     

通胀、通胀预期和货币政策——基于中国2001—2010年数据的实证研究

文章用两种方法测度了我国通胀预期：（1）未来物价预期指数衡量通胀预期;（2）ARMA模型对通胀的预测值。并计量分析了影响通胀预期的因素,结果显示：CPI上升、正产出缺口增加和广义货币供应量增加,是形成通胀预期的主要因素。利率、人民币汇率和食品价格对通胀预期的形成作用不显著和影响较小。因此,存款准备金率动态微调,是目前管理好通胀预期的最好选择。

归因偏差视角下旅游行为失范成因研究

游客旅游行为失范时有发生,威胁着旅游资源与环境安全。心理归因影响个体行为逻辑,归因偏差是解释心理归因的经典理论。本文引入归因偏差理论,采用实证方法探究旅游行为失范背后的归因偏差因素,为减少旅游行为失范提供心理学依据。研究发现,归因偏差能够引致旅游者心理认知偏差,后者直接引发和助推旅游行为失范。心理环境和群体心理对引致旅游者的心理认知偏差和行为失范具有显著作用,归因偏差成为旅游者弱化旅游行为失范结果的心理屏障,可激发或促进旅游行为失范的发生或持续。研究认为旅游地可从完善硬件监控、控制游客流量、强化失范行为负面教育、发挥在场监督作用等方式削弱归因偏差效应。     

In search of diners responsive to health cues: Insights from U.S. consumers

Many consumers rely on summary statistics offered by online and mobile platforms to attain nutrition information on menu items. While positive (vs. negative) summary cues garner more favorable consumer responses, this research provides a more nuanced understanding of this effect by examining the moderating role of two individual-level characteristics: health-consciousness and need for status. Two MTurk samples (Study 1: n = 142, Study 2: n = 119) were recruited in 2018. Findings from Study 1 suggest that health-conscious (vs. less health-conscious) consumers show a wider gap in perceived healthiness of a menu item in response to the valence of a health cue. This greater gap translates into more polarized attitudes toward the menu item. Findings from Study 2 indicate that consumers high (vs. low) in need for status exhibit less favorable attitudes toward a menu item with a negative health cue. Theoretical and managerial implications are discussed.     

网络柠檬问题的表现、影响及营销启示—消费者行为视角

柠檬问题是逆向选择问题在产品市场上的表现,与传统市场一样,网络市场上同样存在柠檬问题.本文从消费者行为的角度分析了网络柠檬问题的表现及影响,认为网络柠檬问题主要产生于企业向消费者传递信息、消费者信息搜集以及消费者处理信息三个过程中,网络柠檬问题阻碍了消费者购买意图到购买行为的转变,最后本文探讨了网络柠檬问题的营销学启示.     

旅游地意象、地方依恋与旅游者环境责任行为——以浙江省旅游度假区为例

文章综合旅游地意象、地方依恋及环境责任行为理论,将旅游地意象分为5个要素,将地方依恋分为2个要素,并构建了旅游地意象、地方依恋与旅游者环境责任行为之间的关系模型。研究发现:(1)景观意象、设施意象、服务意象及安全意象均直接影响情感意象。设施意象与服务意象不仅直接影响地方依赖,且通过情感意象来实现。安全意象和景观意象间接影响地方依赖。安全意象、服务意象及景观意象不仅直接影响地方认同,且通过地方依赖来实现。设施意象间接影响地方认同。服务意象不仅直接影响旅游者环境责任行为,且通过地方依恋来实现。景观意象、设施意象及安全意象间接影响旅游者环境责任行为。(2)情感意象直接影响地方依赖,间接影响地方认同与旅游者环境责任行为。(3)地方依赖直接影响地方认同和旅游者环境责任行为,且通过地方认同间接影响旅游者环境责任行为。

我国城镇消费者有机农产品消费行为分析

目前,国际市场对有机农产品需求不断提高,营养、安全与价格在我国消费者购买评价有机农产品时居于重要地位。基于对北京、武汉消费者的调查,本文统计评价了我国消费者对有机农产品的认知水平,并对有机农产品消费行为及其影响决策因素进行了分析,发现我国消费者对有机农产品的整体认知水平偏低,这是导致我国有机农产品购买水平不高的重要因素。
