Home-end and activity-end preferences for access to and egress from train stations in the Copenhagen region

Increasing public transport use with the aim of improving the sustainability of cities should focus not only on enhancing level and quality of the service offered, but also on understanding determinants of the choice of access and egress modes to and from the railway network. This study analyzes the difference in preferences at the home-end and activity-end for travelers who have chosen train as their main travel mode while investigating the effect of policy variables such as car parking availability, bicycle parking availability and type, and bicycle on train possibility. Specifically, this study analyzes the choices between five transport modes (i.e., “walk,” “bicycle,” “car driver,” “car passenger,” “bus”) for 2921 home-end and 3658 activity-end trips. Joint mixed logit models are specified and estimated to account for heteroscedasticity and correlation across alternative modes as well as taste heterogeneity across travelers. Model estimates and pseudo-elasticities uncover the importance of travel time and underline how the improvement of walkability, bikeability, and bus service would contribute significantly to the increase in the probability of choosing sustainable modes to and from train stations. Moreover, model results emphasize the role of bicycle parking in terms of the sheer number of spaces to be increased as well as covered places to be offered at the activity end, de facto giving the possibility to leave a bicycle at that end during the night. Lastly, model results show that it is a matter of not only time and trip characteristics, but also traveler characteristics, occupation, and purpose.     

How do hotels choose their location? Evidence from hotels in Beijing

This study aims to investigate potential factors contributing to the hotel location choice by an ordered logit model incorporating both hotel and location characteristics. The results suggest that, star rating, years after opening, service diversification, ownership, agglomeration effect, public service infrastructure, road accessibility, subway accessibility, and accessibility to tourism sites are important determinants. By examining location models for different periods, different star rating levels, and different ownership, we show that, downscale hotels tend not to actively seek the benefits of agglomeration effects while upscale ones are more sensitive to accessibility. Finally, agglomeration effects are further investigated by looking into agglomeration heterogeneity, agglomeration scope, scale related and ownership related agglomeration, and agglomeration zoning.     

A discrete‐time hazard analysis of the exit of burley tobacco growers in Tennessee,North Carolina,and Virginia

This article examines the exit and survival dynamics of burley tobacco growers in Tennessee, North Carolina, and Virginia using a discrete‐time hazard logit model. The study also predicts the effects of selected farm and family characteristics on exit hazards, assesses the proportionality of their effects over time and their relative importance in explaining the variation in exit hazards among burley tobacco growers. Results provide the longitudinal progression of the probability of exiting the tobacco industry since the end of the federal tobacco program in 2004, and identify off‐farm participation, percentage of farm receipts from tobacco, tobacco price, educational level, and farm size as the most important determinants of the decision to exit the tobacco industry. Further, the effects of off‐farm participation and farm size on the exit hazards of burley tobacco farms are proportional over time while the effects of the percentage of farm receipts from tobacco and tobacco price are time variant.     

京津沪外来人口迁移行为影响因素对比分析

以2008年京、津、沪、穗四大城市外来人口问卷调查资料为基础,对比分析了北京、天津和上海迁移人口的个体特征以及相对于其他省市,三座城市与迁出地在经济和社会发展差异上对外来人口迁移行为的影响,讨论了人口迁移对地区间不均衡程度的影响。无论是在个体特征方面,还是受经济和社会发展影响方面,天津和上海的迁移人口都具有较多的趋同性;北京市由于其特殊的城市功能以及拥有众多优势资源,对高素质人才具有较强的吸引力,经济和社会的发展等因素对迁移者迁移概率的影响有所不同。     

基于出游动机的游客目的地选择的离散选择模型研究

旅游目的地选择是游客选择行为研究中研究较为广泛的领域之一.现有文献利用了社会、经济、地理等诸多模型和理论对目的地选择进行了研究和探讨.基于随机效用最大化的离散选择模型在游客目的地选择研究中有广泛的应用,但是缺乏属性交互项对于目的地选择的抑制或者激励作用的研究.本文利用2002年江苏省国内游客抽样调查原始资料数据这一选择完成式类型的数据构建了两个二项Logistic回归模型,讨论了寻求闲适安静环境、探亲访友、公务出游3种出游动机对于出游距离以及旅行花费的影响.研究发现寻求闲适安静环境出游动机的游客倾向于选择远距离的目的地,且这类游客也愿意增加旅行花费;出于探亲访友这一动机出游的游客则更愿意选择靠近自己居所的旅游目的地,且不倾向于增加自身的旅行花费;公务出游的游客倾向于选择远距离目的地,也倾向于增加他们的旅行花费.     

Consumers’ preferences for fresh broccolis: interactive effects between country of origin and organic labels

While international trade in organic products has grown significantly, understanding consumers’ preferences for imported organic foods has remained limited. This research examines the impact of country‐of‐origin labeling on US consumers’ choices of organic foods. Results show that consumer valuation of domestically produced organic broccoli was significantly higher than that of imported organic broccoli. Adding information about USDA organic certification standards/rules for imported products mildly increases consumer valuation of imported organic broccoli in some cases. These findings suggest that providing such information may have a positive impact on consumer willingness to purchase imported organic products.     

Consumer preferences for organic production methods and origin promotions on ornamental plants: evidence from eye‐tracking experiments

The strategic value of organic production and origin promotions may vary based on product end‐use. Conjoint analysis and eye‐tracking technology were used to investigate consumers’ purchase likelihood (PL) and visual search behavior for esthetic and food‐producing ornamental plants. Organic production methods, in‐state, and domestic origins positively impacted participants’ PL. Respondents’ visual attention to the organic production attribute had a strong positive effect on PL for food‐producing plants as did sociodemographic variables. Findings imply that producers and retailers could successfully implement signage emphasizing organic production methods and origin designations to generate consumer interest.     

我国谷子种植户持续种植意愿的影响因素研究

文章通过对3个省(自治区)、5个市,268户谷子种植户的问卷调查,采用logit模型,使用逐步回归分析的方法,对影响谷子种植户持续种植谷子意愿的因素进行了分析。从户主个人基本情况、农户家庭情况、农户农业生产情况、谷子生产情况等4个方面共选择13项调查内容作为解释变量,以第2年是否持续种植谷子作为被解释变量,逐步回归分析结果表明:种植户种植业收入占家庭总收入的比重、种植户家庭耕地面积、谷子种植补贴通过了显著性检验。种植业收入占家庭总收入的比重与谷子持续种植呈显著负相关,比重越高持续种植意愿越低。谷子产量受自然因素影响大,农户从减小风险的角度出发,收入对种植业越依赖谷子的种植意愿越弱。家庭耕地面积与谷子持续种植呈显著正相关,家庭耕地面积越大,谷子被选择种植的机会也就越大,规模效应越明显,持续种植意愿越强。补贴对持续种植意愿呈显著正相关关系,种植补贴意味着更多的收益,积极性就越高。依据分析结果提出了要进一步提升对种植谷子的重视,加大科研投入力度,做好科技成果的转化与推广工作;要加大谷子种植补贴的力度、范围及内容,在良种、农膜、资金等方面对种植户给予支持与补贴,调动农户谷子种植的积极性;推进土地流转,在农户种植规模扩大过程中提高土地规模效益的政策建议。     

Adoption and welfare impacts of multiple agricultural technologies: evidence from eastern Zambia

Using plot level panel data and multinomial endogenous switching regression, this article analyzes the adoption and welfare impacts of multiple agricultural technologies in eastern Zambia. We adapt a multinomial endogenous switching/treatment effect regression framework to correct for selection bias and endogeneity originating from both observed and unobserved heterogeneity. Results indicate that joint adoption of multiple agricultural technologies had greater impacts on crop yields, household incomes, and poverty than the adoption of individual components of the technology package. Our findings suggest that efforts aimed at raising household incomes and reducing poverty should focus on promoting the adoption of multiple agricultural technologies through provision of improved support services such as extension and input supply.     

Assessing Consumer and Producer Preferences for Animal Welfare Using a Common Elicitation Format

We assess pig farmers’ willingness‐to‐accept (WTA) higher farm animal welfare (FAW) standards and consumers’ willingness‐to‐pay (WTP) for thus enhanced standards. The analysis is based on discrete choice experiments with nearly identical choice sets for both farmers (N=140) and consumers (N=554). Based on preference estimates from a random parameter logit (RPL) model, supply and demand curves for high‐welfare pork in Germany are estimated and market equilibria are derived for alternative levels of FAW. We find that estimates of consumer WTP are significantly positive for all FAW attributes: consumers value more surface space per pig, more bedding and manipulable material, less surgical interventions and shorter transportation times. In contrast, our model revealed significant producer WTA estimates only for surface area per pig and the amount of bedding material on offer, but not for the other FAW attributes. Farmers who expect to continue farming and engage in direct marketing are more likely to adopt higher FAW standards. Male consumers and those who find price more important than brand, origin or taste are less likely to buy high‐welfare pork, as are consumers who never purchase organic meat products. Market simulations for high‐welfare pork indicate increasing divergence between demand and supply with rising FAW standards. We estimate a market share of 44.6% for pork produced in compliance with an entry‐level FAW programme with standards only slightly above the legal minimum. Programmes with more demanding standards are estimated to gain much smaller market shares.
