Elicitation using multiple price list formats

We examine the properties of a popular method for eliciting choices and values from experimental subjects, the multiple price list format. The main advantage of this format is that it is relatively transparent to subjects and provides simple incentives for truthful revelation. The main disadvantages are that it only elicits interval responses, and could be susceptible to framing effects. We consider extensions to address and evaluate these concerns. We conclude that although there are framing effects, they can be controlled for with a design that allows for them. We also find that the elicitation of risk attitudes is sensitive to procedures, subject pools, and the format of the multiple price list table, but that the qualitative findings that participants are generally risk averse is robust. The elicitation of discount rates appear less sensitive to details of the experimental design.

Reconciling sustainability and discounting in Cost–Benefit Analysis: A methodological proposal

The incorporation of the intergenerational equity objective has rendered the traditional Cost–Benefit Analysis (CBA) approach obsolete for the evaluation of projects presenting an important number of environmental externalities and for those whose impacts extend throughout a long period of time.Based on the assumption that applying a discount rate rewards current consumption and, therefore, that it is only possible to introduce a certain intergenerational equity in a Cost–Benefit Analysis, in this work we propose an approach to discounting based on a different rationale for tangible and intangible effects. We designed two indicators of environmental profitability: a) the Intergenerational Transfer Amount (ITA), which quantifies in monetary units what the current generation is willing to pass on future generations when an environmental restoration project is carried out, and b) the Critical Environmental Rate (CER), measures the implicit environmental profitability.These concepts were tested through an empirical case study pertaining to the assessment of an Erosion Control Project in the southeast of Spain. The results yield traditional profitability indicators that are higher — and probably closer — to the real values set by the contemporary society. The information provided by the environmental profitability indicators proposed renders more transparency to the quantification of the levels of intergenerational equity applied, thereby facilitating the difficult reconciliation of the CBA technique with the objective of sustainability.     

创新政策工具组合、创新能力与创新绩效研究

基于2008-2018年我国内地30个省市面板数据，采用面板固定效应模型分析创新政策工具及其交互项对创新能力及创新绩效的影响。结果发现：①供给型和环境型创新政策均有利于促进技术创新能力提升和创新数量增长，需求型创新政策对创新能力及创新绩效的影响均不显著；②需求型、环境型和供给型创新政策两两交互项能够显著提高基础创新能力和技术创新能力，并显著增加创新数量，但对创新质量均呈显著负向影响；③需求型与供给型以及需求型与环境型创新政策组合功能呈协同互补性特征，供给型和环境型创新政策组合功能呈竞争性特征；④基础创新能力在创新政策工具对创新质量的影响中发挥完全中介作用，技术创新能力在创新政策工具对创新数量的影响中发挥完全中介作用。     

Can intertemporal choice experiments elicit time preferences for consumption?

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments. JEL Classification C90, C91, D90, D91, D11, D12     

项目投资决策中折现率的选择

项目投资是否可行需要根据决策评价指标来判断,而评价指标的计算离不开折现率,其高低对决策结果起着关键性作用.所以,要正确选择折现率,提高决策质量.

Quantity price discrimination in the air transport industry: The easyJet case

This paper extends the literature on low-cost carriers' pricing strategies by investigating the presence of quantity price discrimination implemented through a two-part tariff in offered fares. By analysing Internet fares for all easyJet flights departing from the Amsterdam Schiphol airport between March and April 2015, we search for price differentials based on the number of seats booked by a single consumer. We find that the lowest average unit price is associated with a single consumer reserving 5 seats. On average, the per-seat discount for a single consumer reserving 5 seats is €9.48, which is 14% of the single-seat fare. Additionally, a multivariate analysis shows that quantity discounts are greater for flights with a larger fraction of available seats at the time of booking, the seats are booked longer in advance, and the destination's gross domestic product per capita is greater. Conversely, quantity discounts are lower for longer routes, larger destination airports, and routes for which easyJet's market share is higher.

互联网发展与创新绩效:三维理论框架和异质性验证

在新一轮科技革命背景下,企业经济活动越来越依赖于互联网,因此探讨中国互联网发展能否有效提升创新绩效,具有重要的理论价值和现实意义。文章构建了互联网发展影响创新绩效的三维理论框架,同时从"质量-数量"二分视角,采用2011-2016年省际面板数据,借助面板个体效应模型对二者相关关系予以实证分析,研究结论如下：（1）互联网通过去壁垒、去中心、去中介,从要素、组织、生产范式三个维度分别经由要素重组、组织变革和供需迭代促进了创新绩效。（2）在全国层面,互联网发展和创新质量间存在U型关系,而互联网发展与创新数量间则表现为倒U型关系,且拐点值存在明显差异。（3）在分区域层面,东中西部互联网发展与创新质量间分别呈现出U型、U型、倒U型关系,与创新数量则均表现为倒U型关系。（4）由于不同省份2016年互联网发展水平分布在拟合线拐点两侧的位置不同,各省份未来政策着力点有所差异。（5）数据驱动、生态网络、用户主导分别与互联网发展深度复合影响了创新绩效,但在显著度上存在差异。综上,应从互联网建设、推广与应用,研判区域异质性,发挥调节变量的正向效应三方面重点突破,最大化互联网创新绩效,促进经济高质量发展。
