TESTING FOR AFFILIATION IN FIRST‐PRICE AUCTIONS USING ENTRY BEHAVIOR*

In this article, we show that affiliation among potential bidders' private information (either private signals or entry costs) leads to affiliation among their entry decisions. We propose a test for affiliation among potential bidders' private information based on the implication of affiliation on the entry behavior, which is general and widely applicable to various scenarios. The test is implemented using the simulation based method. We then apply our method to timber sales in the Oregon Department of Forestry and find a small but strongly significant level of affiliation among all timber companies.     

Less is more: A theory of minimalist luxury

We show theoretically that when high-quality, low-price counterfeits exist and are visibly indistinguishable from authentic products, the status-seeking wealthy may embrace a “less is more” purchasing strategy or what we refer to as the minimalist luxury strategy, to signal their status. These are the wealthy who have a high disutility of shopping for counterfeits. Specifically, in our model, only buyers know the authenticity of their own purchases. Because of this information asymmetry, these wealthy buyers may purposefully restrain from consuming luxury goods as a sacrifice of functional utility to stand out, a signaling strategy that the rest are not willing to mimic. Thus, “less” functional utility allows those status-seeking wealthy to enjoy “more” symbolic utility that the society bestows on their perceived status. This minimalist luxury strategy is in sharp contrast to Veblen's conspicuous consumption strategy, as well as to the maximalist luxury strategy proposed by Liu et al. We derive this minimalist luxury equilibrium, discuss how signaling in our context can differ from that of Veblen and Liu et al., and explore its managerial implications for the luxury goods industry.     

农户种植番茄选择行为影响因素的实证分析

本文利用新疆昌吉市284个农户调查资料,采用统计分析和Logit二元选择模型对农户种植番茄选择行为影响因素进行实证分析.结果显示,户主性别、文化程度、劳动力人数、种植面积、种植作物种类、产量因素、价格因素和运输因素对农户种植番茄选择行为有正向显著影响;户主年龄、家庭总人口数、家庭纯收入、是否有非农收入、成本因素、户主风险态度等因素对农户种植番茄选择行为有负向显著影响.     

市场导向对物业服务企业绩效的影响——基于组织学习的中介效应研究

以北京、山东、湖南、广东四省市的物业服务企业为样本,借鉴成熟的市场导向量表和组织学习量表设计调查问卷,就物业服务企业市场导向对绩效的影响进行实证研究,结果表明,市场导向对企业绩效有正向的直接作用,同时通过组织学习对企业绩效产生间接的正向作用,即组织学习为不完全中间变量。研究证明,我国物业服务企业实施市场导向战略能够有效提升企业绩效,基于环境和行业发展的独特性,在实施市场导向战略时尤其要注重开展组织学习。     

中国城镇居民的劳动供给行为——倒S型劳动供给曲线在中国城镇劳动力市场上的实证检验

依据2002年中国家庭收入项目(CHIP)数据,本文应用微观经济计量方法估计了城镇居民的就业方程和工作时间方程。研究结果表明,随着教育年限的增加,个体就业概率不断增加;随着家庭其他收入的增加,个体就业倾向逐渐降低,工作时间逐渐减少;随着家庭人口数的增加,就业个体的工作时间逐渐增加。低收入群体女性和男性工作时间的工资弹性分别为-0.3237和-0.3167,而女性中高收入群体工作时间的工资弹性为0.1429,说明倒S型劳动供给曲线在2002年中国城镇劳动力市场是存在的。因此,政府部门应结合经济发展水平适时地提高最低工资标准,完善社会保障制度,同时加大对低收入群体教育和培训投入力度,促进低收入群体社会福利水平的改善。     

Effect of religious priming in prosocial and destructive behaviour

In this paper, we study the behavioural impact of religious priming by showing participants religious words in a scrambled sentence task before a dictator game and a joy‐of‐destruction game. We also elicited data on individual religiosity and religious affiliation using a questionnaire. Priming religious words significantly increased prosocial behaviour in the dictator game, and the effect was especially striking among those reporting no religion, atheists and agnostics. The religious prime has no significant effect in mitigating destructive behaviour or own expectations of the other's destruction choice, but both destructive behaviour and expectations correlate positively with the multi‐dimensional religiosity measure.     

计及外部性的储能系统价值测算及经济性评估

以应用在电力系统中的电储能系统为研究对象,以外部性理论为基础,构建了计及外部性的储能系统经济性测算模型,并以储能系统接入光伏电站为例,采用贴现现金流分析方法,预估储能投资成本和收益,分别从投资者角度和社会整体效益角度,来研究储能系统应用在可再生能源发电侧的经济性,并进行了盈亏平衡分析。通过盈亏平衡曲线分析了储能盈亏平衡情景,经济性分析结果显示储能系统的外部性收益占年收益比例较大。

Volatility forecasting: long memory,regime switching and heteroscedasticity

In this article, we account for the first time for long memory, regime switching and the conditional time-varying volatility of volatility (heteroscedasticity) to model and forecast market volatility using the heterogeneous autoregressive model of realized volatility (HAR-RV) and its extensions. We present several interesting and notable findings. First, existing models exhibit significant nonlinearity and clustering, which provide empirical evidence on the benefit of introducing regime switching and heteroscedasticity. Second, out-of-sample results indicate that combining regime switching and heteroscedasticity can substantially improve predictive power from a statistical viewpoint. More specifically, our proposed models generally exhibit higher forecasting accuracy. Third, these results are widely consistent across a variety of robustness tests such as different forecasting windows, forecasting models, realized measures, and stock markets. Consequently, this study sheds new light on forecasting future volatility.     

Synergizing independent and cooperative R&D activities: the effects of organisational slack and absorptive capacity

Firms undertaking independent and cooperative research and development (R&D) activities simultaneously often have difficulties to realise their synergistic effects. This study contends that such difficulties are caused by tensions between two types of R&D activities in terms of resource competition and knowledge leakage. Moreover, organisational slack and absorptive capacity may affect these tensions and thereby play important role in synergizing independent and cooperative R&D activities. Based on a survey data of 286 firms, this study finds that such two types of R&D activities jointly have a negative impact on firm performance. Furthermore, organisational slack aids in synergizing them, while absorptive capacity has an adverse impact. These findings enrich our knowledge on the interrelation of independent and cooperative R&D activities and shed light on how firms can synergize them.
