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

选取2021年度数据,采用数据包络分析(DEA)方法对中国东部地区10个省份规模以上工业企业的研发投入绩效进行评价,并采用灰关联分析方法分析确定各项研发投入产出指标相对于DEA效率的灰色关联度。研究结果表明,80%的省份规上工业企业研发投入产出处于非DEA有效状态,存在不同程度的投入冗余或产出不足;规上工业企业发明专利申请数与研发投入产出效率的关联度最高,其次是新产品销售收入和R&D经费内部支出。  相似文献

The concept of consumer ethnocentrism was introduced more than 30 years ago, and since then it has received keen interest among academic researchers. However, empirical evidence in published studies has been inconclusive and many macro-drivers of consumer ethnocentrism received cursory attention. This study meta-analyses 240 studies from 57 countries and tries to understand the key drivers of consumer ethnocentrism. The results indicate that consumer ethnocentrism is a universal phenomenon and is driven by culture and the interaction of economic and ethnic diversity variables. Challenging popular beliefs, the findings suggest that neither globalization nor economic threats are unconditional drivers of consumer ethnocentrism. Their effects are conditional on cultural values and economic situation. Results provide evidence that multi-ethnic societies tend to be more consumer ethnocentric when the culture of a country is not strong in egalitarianism. Finally, the paper presents evidence that consumer ethnocentrism affects the imports of consumer goods in a country.  相似文献

There has been a steady growth of goodwill impairments in the Chinese stock market since the adoption of the impairment approach in accounting. The influence of goodwill impairments on a firm’s financial position and profitability give reason to doubt its current and future performance. We examine whether auditors, as a crucial external monitor, identify the information risks of goodwill impairments and express their concerns about financial reporting quality in their audit opinions. Using a sample of firms listed on China’s A-share market from 2007 to 2017, we test the association between goodwill impairments and the type of audit opinion received in the same financial period. Our findings are as follows. First, the probability of receiving a modified opinion increases with the amount of goodwill impairments. Second, the positive association between goodwill impairments and modified audit opinions is driven primarily by earnings management risks. Third, this positive association is more salient when auditors are industry experts and there is no auditor–client mismatch. Fourth, auditors are more sensitive to the amount of goodwill impairments than to their mere existence. Overall, we document that auditors perceive goodwill impairments as a signal of information risks and communicate their concerns to investors to avoid litigation.  相似文献

Analyzing publicly traded stocks in Korea surrounding IFRS adoption in 2011, we find that the gap between stock price and firm value, value-to-price (V/P) ratio, narrows following the IFRS adoption and that this narrowed gap is observed only for higher V/P firms. We further find that the return predictability of V/P decreases in the post-IFRS period. Using a path analysis, we report further evidence that mandatory IFRS adoption decreases idiosyncratic volatility and improves trading volume and market liquidity, thereby contributing to the narrowed gap between value and price. We conclude that IFRS adoption contributes to resolution of Korea discount.  相似文献

实现区域经济协调发展是当前我国在块集聚与点极化双重压力下面临的现实难题,长江经济带尤其是欠发达省份承接发达地区产业转移是解决该难题的必然路径选择。产业转移活动因区域主客体特征变量不同,呈现出典型的多发式转移和门槛转移特征,使得区域政策制定缺乏科学指导,陷入盲目拼政策红利的状态。结合效率模型及考虑熵权的经济社会发展协同度分析,测算了2004-2016长江经济带各省(市)年综合产业转移效率,并考察了门槛效应值及变化趋势。结果表明:在考察期内,长江经济带各省(市)产业转移效率提升较为明显,但不少省(市)存在不协调的阶段性平衡关系,且这种关系还未显露经济总量驱动下的协同发展能力。  相似文献

近年海洋经济的高速发展及海洋资源的不合理开发利用,给广东省的海洋资源与环境带来了一系列问题,有必要对海洋环境污染损失的货币价值进行估算,以更好地进行环境的投入与产出比较,将环境保护纳入经济核算体系。通过比较并应用各种货币化计量方法,分别算出珠江入海口海域的海洋渔业价值、水质净化价值等,对珠江入海口海域的生态系统经济价值进行评估,在此基础上,结合计量模型对海洋环境污染损失进行货币化综合计量,得到海洋环境污染造成的经济损失量的保守估计范围为 87.4~106.9 亿元/年。最后,提出广东省应充分使用财政资金的金融手段,建立多渠道、多层次和全方位的海洋环境保护体系,最终达到保护海洋生态环境和资源的目的。  相似文献

Since the level of markets’ information efficiency is key to profiteering by strategic players, Shocks; such as the COVID-19 pandemic, can play a role in the nature of markets’ information efficiency. The martingale difference and conditional heteroscedasticity tests are used to evaluate the Adaptive form of market efficiency for four (4) major stock market indexes in the top four affected economies during the COVID-19 pandemic (USA, Brazil, India, and Russia). Generally, based on the martingale difference spectral test, there is no evidence of a substantial change in the levels of market efficiency for the US and Brazilian stock markets in the short, medium, and long term. However, in the long term, the Indian stock markets became more information inefficient after the coronavirus outbreak while the Russian stock markets become more information efficient. Intuitively, these affect the forecastability and predictability of these markets’ prices and/or returns. Thereby, informing the strategic and trading actions of stock investors (including arbitrageurs) towards profit optimization, portfolio asset selection, portfolio asset adjustment, etc. Similar policy implications are further discussed.  相似文献
