开放式基金风险预警系统研究

开放式基金的风险可分为系统风险和非系统风险两大类，其中的流动性风险是所有风险的集中体现，也是风险预警的重点。开放式基金风险预警系统分为市场环境预警、上市公司经营风险预警、基金流动性风险预警三个子系统，各预警子系统由指标体系、预警界限、数据处理和灯号显示四部分组成，用以预测基金的风险状态。

我国开征储蓄存款利息税的宏观经济效应分析

自我国开征储蓄存款利息税以来，居民储蓄存款并没有停止持续上升的势头，利息税政策基本上无效。其原因是利息税对储蓄的收入效应为正，替代效应为负，且收入效应的绝对值大于替代效应的绝对值。这样，征税后对消费和储蓄的总效应为消费减少而储蓄增加。为此政府应采取措施改善居民对未来收支的预期，并且应加快建设完善高效的资本市场的步伐，引导一部分储蓄存款进入证券投资领域。     

中国与印度外贸比较研究

中国与印度两国国情有很多共同之处，目前是全球经济增长最快的两个国家，两国经济发展模式为世界瞩目。两国的外贸规模和发展速度都呈上升趋势，但两国外贸发展的条件不同，外贸水平以中国为佳，而印度的战略性贸易政策值得借鉴。另一方面，中印之间的贸易问题不少，既有结构性问题，也存在保护主义和渠道沟通问题，因此，应加强双边外贸的发展潜力，并拓展双边经济技术合作的领域。     

普惠金融发展对西部地区乡村振兴影响研究

文章使用2003~2018年西部各省份的相关面板数据作为研究样本,通过构建相关评价指标体系并分别对其乡村振兴和普惠金融发展水平展开定量测算。在此基础上,针对西部地区乡村振兴与普惠金融发展之间可能存在的线性和非线性相关关系进行实证检验。研究结果表明,普惠金融发展确实可以促进乡村振兴,该促进作用对于乡村振兴不同维度均显著,其中对生活富裕的作用效果最为明显,对治理有效和产业兴旺的作用效果依次减弱,对生态宜居的作用效果最弱。同时,普惠金融发展对乡村振兴的促进作用具有非线性特征,即该作用效果随着普惠金融发展水平的提高而增强。此外,地区经济发展、旅游业发展和少儿抚养均对乡村振兴产生正向促进作用。基于此,文章提出改善农村信用环境、发展数字普惠金融和纾解金融供需矛盾等相关建议。     

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.     

Altruism and the Economic Values of Environmental and Social Policies

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population.     

The effect of fertility on labour force participation: The Spanish evidence

Abstract. The aim of this paper is to estimate the effect of fertility on the decision of labour force participation of married females in Spain, allowing for the existence of unobserved characteristics that affect both fertility and participation. We use a pooling of five waves of the European Household Panel for Spain (1994–1998). Results indicate that not taking into account the unobserved characteristics that affect both variables imposes on average a strong downward bias on the true effect of fertility on participation. This bias is especially strong for highly educated females. We are grateful to Raquel Carrasco and an anonymous referee for helpful comments.
