企业家创新的内在性和外在性

现代经济学构造体系中长期忽视了企业家的作用，而弥补这一点的重要意义就是认识到企业家的创新职能及其重要性。企业家创新有内在性和外在性之别，企业家创新的内在性不受欢迎，而在外在性则相反。我国为实现企业家创新的外在性所要进行的改革任重道远。     

Happiness of economists

We study the importance of economists’ professional situation towards their life satisfaction based on a unique survey of mostly academic economists. On average, economists report to be highly happy with life. Satisfaction is positively related to spending more time on doing research. The lack of a tenured position decreases satisfaction. However, the extent to which the uncertainty created by the tenure system affects satisfaction varies with the contract terms. The effect is stronger if the contract expires in the near future or cannot be extended. Publication success has no effect if it is controlled for academic rank and the contract duration. The finding suggests that publications are rather a means to an end, for example, to acquire a tenured position. While the perceived level of external pressure also has no impact, the perceived change of pressure in recent years is positively related to economists’ life satisfaction. An explanation is that economists have accepted a high level of pressure when entering academia but are not willing to cope with the recent increase.     

Impact of Personal and Situational Factors on Taxpayer Compliance: An Experimental Analysis

This study used a laboratory experiment with monetary incentives to test the impact of three personal factors (moral reasoning, value orientation and risk preference), and three situational factors (the presence/absence of audits, tax inequity, and peer reporting behavior), while controlling for the impact of other demographic characteristics, on tax compliance. Analysis of Covariance (ANCOVA) reveals that all the main effects analyzed are statistically significant and robustly influence tax compliance behavior. These results highlight the importance of obtaining a proper understanding of these factors for developing effective policies for increasing the level of compliance, and indicate that standard enforcement polices based on punishment alone should be supplemented by an information system that would acquaint tax payers with the compliance level of other tax payers; reinforce the concept of fairness of the tax system among tax payers; and develop programs that enhance and appeal to a taxpayer's moral conscience and reinforce social cohesion.     

利用ACE值构造QC-LDPC码

为进一步提升中短码长下准循环低密度奇偶校验(Quasi-cyclic Low-density Parity-check,QC-LDPC) 码的纠错性能,提出了一种综合短环数目和环连通性的QC-LDPC码构造方法。首先,采用Golomb规则构造QC-LDPC码,对基矩阵中的部分元素进行替换预处理,初步降低短环数目;其次,采用所提的利用近似环外信息度（Approximate Cycle Extrinsic message degree,ACE）的消环掩模算法来优化QC-LDPC码,使得掩模后的校验矩阵具有较大的ACE平均值,最终完成QC-LDPC码的构造。该构造方法简单、通用性强,在短环数目和连通性间进行了平衡。与只考虑减少短环数目、增大围长等方法相比,该方法构造的QC-LDPC码有更加优异的纠错性能。     

The Influence of Consumer Degree of Knowledge on Consumer Behavior: The Case of Spanish Olive Oil

This article analyses the influence of perceived quality measured across intrinsic and extrinsic attributes on satisfaction and consumer loyalty for a traditional food product as with PDO (Protected Designation of Origin) olive oil “Aceite del Bajo Aragón.” In addition, the article highlights the influence of consumer's degree of knowledge on these relationships. The results suggest that the main drivers to explain consumers' satisfaction and loyalty are the perceived quality of the intrinsic attributes (color, appearance, flavor, etc.). However, when consumers are classified attending to their degree of knowledge the main explanatory variable of satisfaction and loyalty of the more experienced consumers are the extrinsic attributes of the product (brand name, place of origin, images associated to the product, etc.). These findings allow us to develop important managerial implications for building a brand image for a PDO.     

Generational Gap： Intrinsic （Non-monetary） Versus Extrinsic （Monetary） Rewards in the Workforce

Traditionally, organizations assume that compensation/pay and monetary benefits are what all employees need to work harder, be productive, or remain with the company. According to Abraham Maslow, within every person is a hierarchy of five needs： physiological needs, safety needs, social needs, esteem needs, and self-actualization needs Organizations must be able to identify what employees desire to secure optimum performance and to meet the needs of both employees and employers. This research focuses on the generational gap and the significance of intrinsic and extrinsic rewards in the workforce. The purpose and objective of this research are to test the significance of monetary versus non-monetary rewards among the different generations in the organization. A self-designed questionnaire distributed to a multi-generational group of employees of selected organizations was used to collect the analyzed data. Sixty-five （65%） responses were obtained. Secondary data were used to elucidate the needs in this area of study. Because the workforce is predicted to become more diverse in terms of age, organizations will be unlikely to implement one set of rewards for the multiple generations. This is due to the differing expectations and requirements among the generations. However, the results indicate no significant difference in monetary versus non-monetary rewards among the different generations in the workforce.

The Effects of Performance Measurement and Compensation on Motivation: An Empirical Study

Summary This paper analyzes empirically the relationship between pay and performance. Economic and psychological theories predict that the design and implementation of a performance measurement and compensation system affect the motivation of employees. Our survey results demonstrate a positive relationship between the perceived characteristics of the complete compensation system and extrinsic motivation. Intrinsic motivation is not affected by the design of monetary compensation, but by promotion opportunities. The compensation system also significantly affects work satisfaction and turnover intent. Our results have both managerial as well as policy implications. We would like to thank the organization and the participants of the 2002 conference of the Performance Measurement Association in Boston for helpful discussions and also seminar participants of the Dutch Labor Market Conference. We are grateful for the comments provided by Bruno S. Frey. The paper has also significantly benefited from the suggestions and comments of two anonymous referees.     

Self-gifting as a therapeutic reward: motivational approach for self-gifting promotions

This study uncovers a motivational mechanism of self-gifting and argues for a therapeutic reward of self-gifting in the context of success. The effects of external motivation of achievement as the underlying antecedent of perceived sacrifice on inspiring materialistic self-gifting behavior are investigated. A total of 774 respondents participated in an online survey posted via the nationwide crowdsourcing web service (MTurk) in the US. The results revealed that extrinsic motivation, internal locus of achievement causality, perceived sacrifice and self-achievement evaluations are indicators for predicting material self-rewarding intention. Further practical and academic implications in marketing communications are discussed in this paper.     

The effect of religiosity on luxury goods: The case of Chilean youths

Religion has always rejected the concept of materialism and urged people to live in simplicity and moderation. Nonetheless, reality reveals a different phenomenon. Studies on religion and materialism have found inconsistent results. We examine the effect of religion on materialism and affective attitudes towards luxury goods and the mediating effect of materialism on affective attitude towards luxury goods. We propose the idea that many religious people reject the concept of materialism, but they consider luxury goods consumption compatible with their religious beliefs. 355 university students show that youth consumers with high intrinsic religiosity possess an affective attitude towards luxury goods. The results show that consumers perceived materialism and luxury goods as two separate constructs. Religious consumers reject the concept of materialism as an attachment to worldly possessions, but they maintain their emotional affection towards luxury goods. The results have several implications for both business and religious leaders. First, from a business perspective, there are no significant differences between religious and nonreligious youth consumers, especially in their acceptance of luxury goods. Simply put, religious youth consumers love God, but they also love Gucci (i.e., luxury goods). On the other hand, if religious leaders are teaching their congregations to reject materialism, they may need to shift the focus of their teaching from materialism to the role of luxury goods in their lives and how the purchase and ownership of luxury items may not reflect the true values of their beliefs.
