房地产税改革、 地方公共服务与区位选择——基于京津冀人口流动的空间黏性视角

我国区域发展极不均衡的现实表明各地房地产价值存在着巨大差异,房地产税改革必须深入探究征税对象所固有的区位属性以及人口城镇化的空间秩序.本文将房地产税改革可能引起的价格效应与地方政府融资和区域公共服务相结合,从人口流动的区位黏性这一全新视角模拟出同一税率下不同城镇化阶段地区的房地产价格走势.结果表明,即使2018年全面开征房地产税,全国房地产价格依然有上涨空间.随着有序疏解北京非首都功能的步伐日益加快,开征房地产税对北京房价有适度抑制作用,天津市与河北省作为北京的"近邻",在功能疏解和产业转移等方面承担着重任,房地产税的价格调控效果不明显.     

The impact of the Social Security Fund on auditor litigation risk

In this study, we examine the effect of the Social Security Fund on auditor litigation risk. Using audit fees as a proxy for auditor perceptions of litigation risk, we find that the Social Security Fund significantly reduces auditor litigation risk. Furthermore, we show that the Social Security Fund influences auditor litigation risk through reducing both the audit risk and the business risk of public companies. In addition, the impact of the Social Security Fund for reducing auditor litigation risk is more obvious in the group of firms with low levels of internal governance, which indicates that the Social Security Fund plays an important governance role as a high-quality institutional investor. In summary, we verify that the Social Security Fund, when acting as an institutional investor, plays an important role in corporate governance, and that it helps to reduce auditor litigation risk. Our results provide empirical support for expanding the governance role of the Social Security Fund as an institutional investor in China’s A-share market.     

信息化发展水平、资源依赖与绿色全要素生产率

信息化作为经济高质量发展的重要推手，对于资源地区走出“资源诅咒”困境意义重大，但一直被学界忽略。创造性地将信息化发展水平引入“资源诅咒”论述中，采用DEA—Malmqusit指数方法测算了2003-2017年我国285个地级及以上城市的绿色全要素生产率（GTFP），分析了信息化发展水平在资源依赖与GTFP关系中的作用。结果表明：①信息化发展水平的门槛效应导致资源依赖与GTFP呈现倒U型曲线关系。当信息化发展水平低于门限值时，无论资源依赖程度如何变化，它与GTFP的关系总是处于倒U型曲线右侧，即位于“资源诅咒”部分，而当信息化发展水平高于门限值时，无论资源依赖程度如何变化，它与GTFP的关系处于倒U型曲线左侧，即位于“资源祝福”部分;②信息化发展水平是显著影响资源依赖与GTFP的倒U型曲线拐点右移的要素，信息化发展水平提升能推迟或阻止“资源诅咒”的到来。

Can fear be eaten? The emotional outcomes of consuming frightening foods or drinks

This paper examines the emotional effects of consuming frightening foods or drinks. We argue that in addition to maintaining energy homeostasis and attaining pleasure, a third possible benefit of eating is the enhancement of perceived mastery over that which is eaten. Hence, the intake of frightening foods or drinks should increase a consumer's self‐confidence in dealing with fear. The findings of our three experimental studies confirm our counterintuitive predictions, namely that consuming frightening (vs. nonfrightening) foods or drinks leads to a significant reduction of fears arising from prior experiences of frightening activities and a significant increase in tolerance of prospective frightening activities. In addition, self‐confidence in dealing with fear is shown to significantly mediate the predicted effects of consuming frightening foods or drinks.     

The fallacy of Washington consensus and the role of the Government: interpreting some Chinese contributions to development policy from aspects of Chang’e 4

Students of economics may have heard of that economics, especially the kind of mainstream neoclassical economics taught in most universities on earth today, is an imitation of physical science in some fundamental fashion. However, few economists would imagine that economics can be as effective as physical science, not even in the remote future. China’s Chang’e 4 mission to the far side of the Moon provides a golden opportunity for economists to explore this fascinating possibility from the aspect of astrodynamics.

This article, inspired by thoughts of Justin Yifu Lin and Angang Hu among others regarding China’s economic reform, demonstrates that physics explaining the Three-Body Problem of classical mechanics may as well be understood as guiding principles when dealing with issues in development economics. Several aspects of ‘Washington consensus’ are examined in relation to the concerns raised by Chinese scholars. The study concludes that neoliberal interpretations of modern economics are basically inconsistent with the neoclassical framework outlined in standard economics textbooks.     

Delivered pricing and endogenous delegation of contract type

This article demonstrates for the first time that owners will delegate the location decision under delivered pricing using a relative performance contract rather than a market share contract. It goes on to evaluate the welfare consequences of this demonstration. With linear production costs and simultaneous location, both incentive contracts reduce welfare, but the chosen relative performance contract reduces it by less. Yet, with linear costs and sequential location, the chosen relative performance contract reduces welfare by more. Finally, with enough convexity in production costs, welfare can be improved by the chosen relative performance contracts.     

知识共享视域下知识领地行为对组织创新绩效影响的实证研究

知识共享是激发个体新思维和新创意的重要动力，是促进企业协同创新发展的关键，但知识的稀缺性和独特性提高了人们对知识所有权的占有率，并导致知识壁垒形成。鉴于此，本文从领地行为出发，分析知识领地行为对组织创新绩效发挥作用的路径机制及外部影响。研究结果表明:个体知识领地行为对组织创新绩效具有显著负向影响；组织知识领地行为对组织创新绩效呈显著正向影响；知识共享与组织创新绩效显著正相关；知识共享在知识领地行为与组织创新绩效之间发挥中介作用。     

放松利率管制、过度负债与债务期限结构

放松利率管制不仅消除了信贷市场摩擦,而且可以通过调整贷款利率水平以实现信贷风险与资金成本之间的匹配,从而对企业资本结构选择产生影响。本文以2000-2015年我国A股非金融类上市公司为研究样本,从企业杠杆选择和债务期限结构两个方面来实证检验放松利率管制如何影响企业资本结构。检验结果发现:放松利率管制不仅显著抑制企业过度负债,加快资本结构调整速度,而且延长企业债务期限。进一步检验还发现,放松利率管制显著抑制企业短贷长投行为,降低企业现金与现金流之间的敏感性。以上问题的研究不仅在理论上证实了放松利率管制影响企业杠杆选择以及资本错配的具体作用机理,而且在实践方面对于我们进一步推进利率市场化进程,完善市场在资源配置中的决定性作用具有重要的政策启示意义。
