The Impact of Omitting Promotion Variables on Simulation Experiments

Using store-level scanner data, elasticity matrices are estimated using a twotiered demand system. Two basic models are estimated, one with promotion variables and one without. Differences between the estimates across the two models are statistically significant. However, when the elasticities are used as 'inputs' into several simulation exercises, there are only small differences in merger effects and patent damage estimates.The results suggest that the differences are not 'economically' significant.     

最低工资对我国就业性别差异的影响研究——基于中国省际面板数据和行业面板数据的分析

文章基于中国1996-2012年省际面板数据和城镇单位行业面板数据,在控制了教育、劳动供给、经济开放、经济发展、就业环境和时间等因素后,考查了相对最低工资和绝对最低工资的提升对城镇单位就业性别差异的影响。结果表明,最低工资对就业性别差异的影响存在自我修正机制,当期影响与滞后影响方向相反;相对最低工资的综合影响以正向为主,但影响较微弱,绝对最低工资的影响主要体现在滞后效应中,综合影响以负向为主;在高工资行业和女性就业集中度较低的行业中,相对最低工资的当期影响存在一致的负向性、滞后影响以正向为主,绝对最低工资的当期影响以负向为主、滞后影响以正向为主;在女性就业集中度较高的行业中绝对工资的滞后影响以负向为主。     

Are some entrepreneurs more overconfident than others?

Entrepreneurs are more susceptible to certain cognitive biases than are managers who are not entrepreneurs, but it is not clear why. In an effort to help explain why, I examine differences in the degree to which entrepreneurs exhibit the overconfidence bias. Results show that individual age, firm decision comprehensiveness and external equity funding affect the degree to which entrepreneurs are overconfident. In addition, founder-managers are shown to be more overconfident than are new-venture managers who did not found their firms. The results suggest that entrepreneurs' cognitive biases are a function of both individual and contextual factors.

非参数回归技术在经济计量模型分析中的应用

在微观计量经济研究中,居民收入与消费分布结构的研究通常采用参数模型进行实证分析,但是实际经济环境中往往存在一些不确定的因素,参数模型所提供的结果并不完全与实际相符合。在计量经济模型分析中采用非参数回归技术,在数据较多的情况下,不需要预先确定变量之间的函数关系,可灵活机动的从多个方面考察收入与消费的相依关系和变化趋势,并可以证明非参数方法的结果优于常规的参数方法。     

ROBUST PORTFOLIOS AND WEAK INCENTIVES IN LONG‐RUN INVESTMENTS

When the planning horizon is long, and the safe asset grows indefinitely, isoelastic portfolios are nearly optimal for investors who are close to isoelastic for high wealth, and not too risk averse for low wealth. We prove this result in a general arbitrage‐free, frictionless, semimartingale model. As a consequence, optimal portfolios are robust to the perturbations in preferences induced by common option compensation schemes, and such incentives are weaker when their horizon is longer. Robust option incentives are possible, but require several, arbitrarily large exercise prices, and are not always convex.     

Emerging Paths of Family Entrepreneurship Research*

This futuristic commentary reviews family business research since its beginning more than 30 years ago. Prior to 2000, disciplinary roots, professional organizations, and early milestones are identified. More recent books, journals, and special issues are noted, and conceptualizations, theories, and databases are compared and contrasted. Lastly, current and future research paths or directions are identified and discussed, and researchers are challenged to move ahead into new and different research arenas.     

加强国有资产管理努力创建节约型海关

当前,海关单位国有资产管理方面存在的问题,主要是管理不严、责权不清;购进实物资产,缺乏严密的验收审批程序。导致“重业务、轻资产,重建设、轻管理”的原因,主要在于管理机构不健全,管理人员缺乏;管理手段落后,效能不高;制度建设滞后,管理不规范;海关单位的资产调剂困难等。海关单位应提高认识,建章立制,强化国有资产管理观念;全面清产核资,摸清家底;加强对出租房屋的监管;充分利用预算、政府采购强化对资产的配置管理;加强固定资产的事中、事后监控;加强对国有资产管理人员的培养,使国有资产管理工作规范化、科学化、专业化。

Understanding how retail environments are perceived: a conceptualization and a pilot study

A conceptual framework for understanding how perceptions of retail environments are formed is developed in this paper. In developing the framework, three main issues receive theoretical attention. First, the problem of conceptualizing retail environments is tackled. Second, the dimensions of environmental perception are discussed from the standpoint of retail arenas. Third, the factors that moderate how different retail environments are perceived are treated producing a few research propositions. The article also reports the findings of a pilot study. Both quantitative and qualitative analyses are conducted and they show that the separate perceptual dimensions manifest themselves in distinct ways in different retail environments. Finally, the theoretical and managerial implications are discussed and future research suggestions are spelled out.     

Location Advantages,Firm Advantages,and Export Success in the Latin American Automotive Parts Industry

Abstract

This paper examines the influence of location advantages and firm-level advantages on the propensity of Latin American firms to export. An empirical test based on Latin American firms in the automobile parts industry suggests that firms in more competitive Latin American country environments are more likely to export than those in less competitive country environments. Also, older and larger firms are more likely to export than are younger and smaller firms, and businesses that are subsidiary companies are more likely to export than are independent companies. Implications for managers and policy makers are presented.     

Culture,leadership and motivation in two Commonwealth Caribbean countries: One look at the African Diaspora

Little is known of Caribbean people's views on their culture or of their beliefs regarding leadership and motivation. This study reports the results of a Delphi Technique with people in leadership positions and focus groups. Across groups, responses were relatively consistent: ethnicity and culture are described as influenced by religion, and Christianity in particular; African roots and country of origin are important; effective leaders are charismatic, visionary, results oriented, and they motivate others, lead by example, and develop vision and goals. Leaders believe motivation comes from making a difference for others. Nonleaders believe leaders are influenced by financial rewards and self‐fulfilment; nonleaders are motivated primarily by financial rewards. The results are generally similar to Western beliefs, but some interesting differences are identified. Copyright © 2014 ASAC. Published by John Wiley & Sons, Ltd.     

Brand Networks as the Interplay of Identities,Selves, and Turtles: Commentary on “Interplay between intended brand identity and identities in a Nike related brand community: Co-existing synergies and tensions in a nested system”

This commentary emphasizes the networked nature of brands. Brands are identities, and identities are meanings. Meanings are always embedded in networks of association. Therefore, all understandings of brands are necessarily vast, complex, and incomplete, especially in the contemporary age of branding.     

Hyperfiliation and cultural citizenship: African American consumer acculturation

The experiences of African American expatriates in South Africa are explored to explain how acculturation in circumstances of hyperfiliation influences cross-cultural consumption for the purposes of performing cultural citizenship. The acculturation sub-processes of revision, restoration, and retroversion are analyzed to examine the ways in which social capital is mobilized in citizenship projects. These aspects of expatriate experiences are unpacked, theoretical implications are identified, and managerial implications are discussed.

Spending propensity and price perceptions

ABSTRACT

This article presents a systematic investigation of how Spending Propensity moderates consumers’ perceptions of prices. Results from three studies are presented. Studies 1 and 2 reveal that, in the absence of any external cues, consumers who are predisposed to spending freely evaluate a posted price more favorably than those who are not. Such consumers also report anticipating less pain associated with spending than those who are not inclined to spend. Additionally, Study 2 informs that simple price communication tactics, without any real reduction in price, may be effective at mitigating the pain felt among those who are less inclined to spend. Furthermore, such tactics are capable of reducing, and even reversing, the gap between those who are not predisposed to spending and those who are. Finally, Study 3 explores how spending propensity moderates consumers’ perceptions of a discount.
