Empirical evidence suggests that women are discriminated against in the labor market. We analyze the effects of taste-based and statistical gender discrimination on business cycle and inflation dynamics by including unpaid household production, two-agent households, and discriminatory firm behavior in a tractable New Keynesian model. After a negative demand shock, we find that the economic downturn is more severe in comparison to a non-discriminatory environment, as the shock implies an increase in the inefficient utilization of female and male productivity. Furthermore, the working time allocation between women and men becomes more inefficient. Moreover, we show that discrimination implies a lower transmission of expansionary monetary policy shocks on inflation. Overall, taste-based discrimination leads to larger macroeconomic distortions, while statistical discrimination implies higher intra-household inefficiencies.  相似文献

Improving access to more modern forms of energy requires supply chains that reach further into rural areas. This paper studies a supply-side intervention intended to foster last-mile distribution of energy-access technologies through local small-scale entrepreneurship. We use a staggered-implementation evaluation design to assess the impact on employment and income outcomes of the intervention, which is a large-scale program in Kenya that supports the diffusion of improved cookstoves and small solar products. The results demonstrate how trained entrepreneurs intensify and diversify their income-generating activities, often by shifting away from subsistence farming as a main source of income. For cookstove entrepreneurs, this goes along with improvements in individual and household incomes as well as perceived economic well-being. Our estimates suggest that impacts do not only differ between the two technologies but also across subgroups including gender, age, and baseline occupation. Our findings substantiate that market-based interventions can foster energy access in rural areas by supporting the establishment of local businesses. We highlight several contextual factors that are of relevance when considering the adoption of this approach.  相似文献

完善创新生态系统、提升区域创新能力是我国科技企业孵化器建设的重要目标。基于2013-2018年中国(内地)30个省份面板数据,采用面板数据模型实证检验科技企业孵化器是否促进了区域创新能力提升,并基于中介效应模型探讨风险投资和孵化基金在其中的间接作用。结果发现:①科技企业孵化器建设显著提升了区域创新水平,但主要增加的是实用新型和外观设计专利申请授权数总量,对发明专利申请授权数并没有显著促进作用。上述结果在剔除直辖市样本、采用随机效应模型及空间计量模型的稳健性检验后依然成立;②通过中介效应模型检验发现,区域风险投资和孵化基金集聚效应是科技企业孵化器影响区域创新水平的主要机制;③科技企业孵化器对区域创新的影响在不同区域间差异较大,在东部地区的创新激励效应更加显著,而且政策工具强度对科技企业孵化器与区域创新水平的关系具有正向调节作用。  相似文献

The legal and compliance departments in organizations have more influence than ever before. Why then are companies so vulnerable to legal liability? The problem may not be with talented legal professionals, but with the lack of legal knowledge held by MBAs and other business school graduates that make day-to-day decisions in modern organizations. Firms can close this knowledge gap and minimize legal liability by training their managers in legal astuteness—the ability of a manager to address legal issues successfully—by instilling four essential traits: respecting the rule of law, recognizing legal issues, resolving problems proactively, and reporting complex legal issues to experts. Job candidates should also be screened for traits of legal astuteness. A legally astute candidate, especially a graduate of a business school that requires legal education for all its students, can be a cultural ambassador for legal astuteness and a valuable liaison between legal and compliance departments and the candidate’s functional area. A legally ignorant candidate will require significant training and a frank assessment of the legal risk they bring to the organization. Modern firms in today’s legal environment face two choices: hire a legally astute manager now or deal with a compliance headache later.  相似文献

We study how local leaders matter for economic growth by examining the impacts of exogenous transfers of leaders across China’s provinces on land transactions in the primary market. We find that new provincial leaders attract investment in industrial land from the provinces of their previous positions. The leaders’ impacts are greater when their freedom to deploy their business connections in the land market is greater. More importantly, we find evidence of positive impacts of land transactions on economic growth, which should bode well for the careers of the local leaders, albeit there is some evidence of rent seeking among officials especially when they are too old for further promotion.  相似文献

This paper addresses the debate over aggressive tax‐planning models and analyzes the role of tax consultants. It focuses on the dynamic interaction between innovation and imitation of aggressive tax‐planning products and governmental tax regulation, and it highlights the importance of the length of regulatory lag in comparison with the time it takes the tax‐consulting industry to imitate newly innovated tax‐avoidance products. It reveals an alignment of interests between highly innovative tax‐consulting firms and the governmental tax legislator/regulator. The conclusions are also relevant for the policy debate on mandatory disclosure rules about aggressive tax‐planning models.  相似文献

当前我国居民消费不足的最主要原因在于居民收入水平不高、国民收入分配失衡,所以2018年个人所得税改革的重点是提高费用扣除标准、调整税率结构,降低纳税人负担,增加纳税人可支配收入,提高居民消费水平。要进一步促进居民消费,个人所得税有必要继续减税,同时进一步调节收入分配差距,使收入分配更加公平。具体对策包括:将专项附加扣除中的子女教育支出范围扩大为子女养育支出,增加家庭合并征税模式,费用扣除标准指数化动态调整,进一步优化税率结构,建立负所得税制度。  相似文献

以纳税信用评级披露作为一个天然外生冲击,并基于2013—2016年1214家A股上市公司的微观数据构造准自然实验,使用双重差分法系统评估纳税信用评级结果披露对上市公司研发投入的影响。结果发现:纳税信用评级结果披露显著增加了上市公司的研发投入。基于PSM-DID方法的估计结果与上述结论无明显差异。稳健性检验也表明上述结论的正确性。机制检验表明,纳税信用评级结果披露通过降低企业的融资约束,进而促进企业增加研发投入。此外,分样本回归发现纳税信用评级结果披露只能对中小型企业和民营企业的研发投入产生促进作用。  相似文献

Many experts agree that more agricultural investment is needed in the global South to improve local food security and reduce poverty. However, there is a lack of consensus about the types of investment needed to achieve these goals. This paper contributes to the literature on large agricultural investments and corresponding business models by inventorying and analysing such investments in Kenya’s Nanyuki area. We identify four clusters of business models that differ primarily by type of production and other distinct determinants, namely: demand from markets; access to land; land tenure regime and colonial history; actors involved; biophysical context; labour availability; and governance of the value chain via private standards. The study results shed light on the factors that help or hinder implementation of large agricultural investments and shape their impacts in the context of African land use systems. The way land is accessed represents one of the most-decisive factors determining the risks and opportunities associated with such projects. We find that most investments in the Nanyuki area occur on land bought or leased from private owners.  相似文献

以企业竞争战略选择作为出发点,对不同企业的捐赠行为和动机进行了研究。研究发现,与保守型竞争战略定位的企业不同,进取型竞争战略定位的企业更倾向于慈善捐赠行为,幅度更明显。其中,企业违规次数具有正向调节效应、管理者的政治关联具有负向调节效应,由此可以部分说明进取型企业的慈善捐赠行为有一定“伪善性”,或者是在谋求有利于企业的政治关联性。  相似文献
