High firewood consumption for heating produces high levels of pollution in cities in central and southern Chile, with serious consequences for health and quality of life. Energy efficiency measures (EEMs) have been identified as the best strategy to reduce air pollution and maximize social benefits. However, their adoption has been slow. The objective of this article is to investigate household preferences for financial incentives needed to promote private investments in EEMs in Central-Southern Chilean households and study the role of energy savings and the uncertainty about potential savings in the investment decision, with the aim of finding solutions to increase the adoption of these technologies. We use a choice experiment to explore the trade-off between the investment costs, financial instruments, energy savings, and the uncertainty about achieving the theoretical savings provided by engineering and architectural models. The results show that financial instruments play the most important role in this decision, followed by the savings achieved by the retrofit. Householders prefer to finance their investments with a mix of their personal resources and medium-term credits, trying to avoid long-term commitments. Although uncertainty was found to be a significant variable, it seems to play a small role in the investment decision.  相似文献

Empathy is a key trait distinguishing social entrepreneurs from traditional entrepreneurs, and an important antecedent of social entrepreneurial (SE) intentions. Yet, little research explains the mechanisms through which empathy motivates SE intentions. We argue that studying the link between the prosocial trait of empathy and the prosocial outcome of SE intentions requires a prosocial lens that traditional entrepreneurial intent theories cannot offer. Building on prosocial motives research, we propose that empathy explains SE intentions through two complementary mechanisms: self-efficacy (an agentic mechanism), and social worth (a communal mechanism). We find support for our hypotheses in a study of 281 university students.  相似文献

Many food regulations focus on test/measurement indicators, such as hazard analysis and critical control points (HACCP) and traceability, etc. Other than these indicators, the food industry uses various cues such as product origin as indicators of product quality. However, in an environment where consumers’ confidence in food safety is low due to frequent food safety scandals, little is known about the efficiency of these test/measurement indicators and cues. This paper used the primary data collected in Zhengzhou (China) to estimate consumers’ preferences for test/measurement indicators and a new cue of “own farm” for milk powder. Our results show that country of origin is the most important cue attribute, followed by price and own farm. The importance of test/measurement indicators such as organic, traceability, and HACCP certification is relatively low. Also, the individual parameter estimates show that consumers’ preferences for test/measurement indicators currently in the market are weak and fragile. Interestingly, price has an inverse-U-shaped relationship with consumer utility, implying that Chinese consumers may perceive low-price milk powder as low quality. The results of this study provide important insight for regulatory authorities and the food industry to develop more effective policies and programs to improve consumer preferences for milk powder.  相似文献

主流经济学家把改革开放后民营企业的大规模兴起,主要归因为市场经济条件下发挥企业家精神和遵循比较优势的必然结果。但是这无法解释为什么民营企业在兴起之初就广泛和快速地进入到各个工业,尤其是技术和资本密集型工业。基于中国工业史和252家中国最大民营制造业企业创业发展史的历史证据,文章找回"工业体系"这一被主流所忽略的重大历史现象和学术概念,从而首次提出一种理解中国民营企业发展独特性的结构性解释。文章发现:从计划经济时期继承而来的门类齐全和独立完整的工业体系,是解释民营企业创业和发展独特性的关键变量;已有的由国有企业和科研院所组成的工业体系,从市场机会、技术能力和组织资源等方面塑造了民营企业的创业选择和发展路径。所以,中国民营企业的快速发展不是仅凭自由市场就会自动出现的普遍现象,而是在市场条件下充分利用工业体系提供的技术和市场条件才得以出现的特殊现象。  相似文献

Data from the AICPA (2009b) show that African–Americans comprise only 1% of CPAs and were only 4% of new hires by CPA firms in academic year 2007–2008. The current study uses social cognitive career theory to examine whether this shortage of diversity may be caused by differences between African–American and Caucasian students in factors that lead to career interest in accounting. Students were surveyed on two key personal variables: self-efficacy and outcome expectations. Results suggest that African–American students are more likely than Caucasian students to perceive accounting as providing outcomes that match their values. However, favorable perceptions may be countered by differences in self-efficacy. African–American students value outcomes provided by accounting, but they may have less confidence, compared to Caucasian students, that they can successfully complete the course of action necessary to enter the profession.  相似文献

离散选择模型的基本原理及其发展演进评介   总被引:10,自引:0,他引:10  
离散选择模型的研究真正兴起于19世纪50年代末,属于微观计量经济学的范畴。该模型能够对个体和家庭行为进行经验性的统计分析,因而在经济学和其他社会科学中得到广泛的应用。本文从离散选择模型的基本性质及效用最大化的理论背景出发,指出logit模型虽然使用的是最早并且最为广泛的离散选择模型,但是其存在着三大局限性:不能表示随机口味的变化、暗含成比例的替代形式和不能处理不可观测因素在不同期间相关的情形。GEV(含嵌套logit)、probit和混合logit模型等其他的离散选择模型,很大程度上都是为了避免这些限制而产生并发展起来的。  相似文献

The risk-return trade-off in human capital investment   总被引:6,自引:0,他引:6  
In this paper, we analyze investments in human capital in a way which is standard for financial assets, but not (yet) for human capital assets. We study mean-variance plots of human capital assets. We compare the properties of human capital returns using a performance measure and by using tests for mean-variance spanning. Fields differ strongly not only in common rates of return, but also in return per unit of risk. We identify a range of educations that are efficient in terms of investment goods, and a range of educations that may be chosen for consumption purposes.  相似文献

企业家政府理论的理论局限及启示   总被引:1,自引:0,他引:1  
企业家政府理论是20世纪90年代以来所兴起的国际化政府改革潮流的最主要和直接的理论依据,它对中国的行政理论研究和改革实践产生了巨大的影响。考察企业家政府理论的实质具有重要意义,对其有必要进行理论审视和重新认识。企业家政府理论有三个方面的理论局限:一是普遍实用性的缺失;二是价值理性的缺失;三是基本概念的不确定性。通过对企业家政府理论进行深入考察得出几点启示:一是坚持理论与实践的统一;二是坚持工具理性与价值理性的统一;三是对坚持继承与创新的统一。  相似文献

In this paper we examine how the information processing of subjects who make an innovative choice (innovators) differs from that of subjects who make a noninnovative choice (noninnovators). The task involves selection of an alternative within a range of prerated product category innovativeness. We propose that subjects who seek 1) impersonal/uncontrollable sources, 2) higher levels of information, 3) more detailed (versus summary) data, and 4) noncomparative (versus comparative) data are more likely to make innovative choices. The research method is a computerized process tracing experiment utilizing Search Monitor (Brucks 1988).The authors wish to express their gratitude to Merrie Brucks for the use of and help with Search Monitor and to Eric Johnson, Dave Schmittlein, and Mita Sujan for helpful comments on an earlier version of this paper.  相似文献
