数字普惠金融对地方税收影响的实证研究

采用北京大学测度的2011—2018年数字普惠金融指数与地方税收面板数据，研究了数字普惠金融发展与地方税收之间的关系。研究发现，数字普惠金融能够显著地促进地方税收增长，在考虑了内生性等因素后，这一结论仍然稳健地成立。分位数回归表明，数字普惠金融在低分位数上对地方税收影响小且统计显著性弱，在高分位数上数字普惠金融对地方税收的影响大且统计显著性强。数字普惠金融对地方税收的影响存在门槛效应，在不同发展阶段，其对地方税收影响有显著差异。数字普惠金融促进税收增长主要是通过数字普惠金融覆盖广度提高和移动化、便利化等程度加深实现的。     

博弈视角下大学生互联网消费信贷决策行为研究

基于博弈论视角,从理论上构建了金融机构与大学生消费信贷决策的动态博弈模型,并引入信誉机制,比较分析了传统金融机构退出大学生信用卡市场而互联网金融大举进入校园信贷市场的深刻原因,同时借助大学生消费信贷调查一手数据实证检验了信誉机制的有效性,研究结果表明:在单次和有限次重复博弈中,“囚徒困境”普遍存在,而在无限次重复博弈中,尽管利率和交易成本下降有利于促进交易,但信息不对称问题却使博弈只能进行有限次,因此要达成长期合作,必须引入具有“社会性惩罚”的信誉机制来抑制大学生的短期投机行为,然信誉机制对于促进传统金融机构与大学生合作的作用有限,更多的是促进互联网金融机构与大学生消费信贷关系的达成,实证结果验证了该结论。由此得到的启示是,充分利用互联网大数据优势、强化互联网金融市场监管、引导大学生树立正确的消费观和责任意识,有助于破解“一放就乱,一管就死”的监管困局,这对于规范互联网金融校园消费信贷市场具有重要现实意义。     

低碳视角下多式联运经济性能实例分析--以郑明物流为例

为了进一步研究铁路运输与其他运输方式开展多式联运的经济性能,在阐述多种运输方式性能差异的基础上,以郑明物流为例,通过分析其特定运输路线现有运输方式的能源消耗、碳排放量和运输过路费等指标,提出在不同月份和不同时期的多式联运优化方案,为物流企业开展多式联运提供借鉴。     

城乡炫耀性消费差异的根源探索

运用中国家庭追踪调查数据,研究发现:农村家庭的炫耀性消费支出比例显著高于城镇家庭,且这一结果随时间变化比较稳健。进一步研究发现,在考虑了家庭参照群体的平均收入之后,城乡炫耀性消费差异不再显著,且参照群体的平均收入对家庭炫耀性消费的影响显著为负。这很可能来源于家庭为寻求社会地位而消费的动机,更高的社会地位意味着更多的财富和带来更高的收益。炫耀性消费充当了家庭社会地位的信号,向其参照群体传递了自身的收入水平状况,参照群体的平均收入越低,消费者寻求社会地位的消费动机越强。农村家庭参照群体的平均收入较低,所以其寻求社会地位的动机更强、炫耀性消费水平更高。因此,寻求社会地位的消费动机是城乡炫耀性消费差异的主要原因。     

地方政府间税收竞争会诱发过度投资吗*

政府行为的策略变化是否会引起企业行为的变化？本文以地方政府间税收竞争为切入点，研究其对企业过度投资的影响。本文首先利用工业企业数据库中的制造业企业，测算出企业投资效率并保留其中过度投资的样本；其次利用地级市经济社会数据构造出税收竞争指标，实证检验税收竞争对企业过度投资的影响，并进行相应的异质性分析和稳健性检验。实证研究发现税收竞争显著促进企业过度投资，而且对非国有企业的过度投资行为影响更大。本文的研究结论对当前我国产业结构调整、破解产能过剩等问题有一定的借鉴意义。     

房价对居民消费的跨空间影响*——基于中国278个城市空间面板数据的实证研究

本文首先基于住房财富效应，构建了房价变动对居民消费的跨空间影响的分析框架。该框架阐释了住房财富效应的区域差异：不同地区间房价的空间传导、居民的异地消费以及消费的示范效应，使得本地房价变动可能引起周边地区居民消费的连锁反应。其后，本文利用中国278个地级市2000—2018年数据，通过空间面板杜宾模型，实证考察了不同地区住房财富效应的差异，以及房价变动对居民消费的跨空间影响。结果显示：（1）虽然中国整体上存在住房财富效应，但西部城市财富效应并不显著，并且核心城市还存在负财富效应。（2）不同城市间房价对消费存在跨区影响。东部城市和核心城市对周边城市消费的正向影响很显著，而边缘城市则对周边城市消费有显著的负向影响。（3）不同城市间的消费也具有空间上的示范效应。最后，本文从房价和居民消费空间联动的视角，为政府扩大内需、调控房地产市场提供了相关政策建议。     

Consumption,asset wealth,equity premium,term spread,and flight to quality

We link transitory deviations of consumption from its equilibrium relationship with aggregate wealth and labor income to equity returns on the one hand, and to two characteristics of bond investors—the premium demanded to hold long‐term assets, and “flight to quality” behavior—on the other hand. Using a panel of 10 euro area countries over the period 1984Q1–2017Q4, we show that a rise in the consumption–wealth ratio predicts both higher equity returns and the future term spread, while a fall in the consumption–wealth ratio explains a large fraction of the rise in the spread between the “risky” and the “safe‐haven” bond.     

Monetary Policy Uncertainty and the Response of the Yield Curve to Policy Shocks

This paper studies the nonlinear response of the term structure of interest rates to monetary policy shocks and presents a new stylized fact. We show that uncertainty about monetary policy changes the way the term structure responds to monetary policy. A policy tightening leads to a significantly smaller increase in long-term bond yields if policy uncertainty is high at the time of the shock. We also look at the decomposition of bond yields into expectations about future policy and the term premium. The weaker response of yields is driven by the fall in term premia, which fall more strongly if uncertainty about policy is high. Conditional on a monetary policy shock, higher uncertainty about monetary policy tends to make securities with longer maturities relatively more attractive to investors. As a consequence, investors demand even lower term premia. These findings are robust to the measurement of monetary policy uncertainty, the definition of the monetary policy shock, and to changing the model specification.     

What's on the Menu? Policies to Reduce Young People's Sugar Consumption

Young people in the UK consume far above the maximum recommended levels of added sugar. It is likely that neither they nor their parents fully take account of the future health, social and economic costs of this high sugar consumption. This provides a rationale for policy intervention. The majority of young people's added sugar consumption occurs in the home, where purchases are typically made by parents. This means that understanding the purchase decisions of adults is important for policy design, even if the policies aim to reduce the consumption of young people. We discuss the merits of popular policies, including taxes, advertising restrictions and restrictions on the availability of specific foods, and we identify promising avenues for future research.     

The Income and Consumption Effects of COVID-19 and the Role of Public Policy*

We provide empirical evidence on the labour market impacts of COVID-19 in the UK and assess the effectiveness of mitigation policies. We estimate the relationship between employment outcomes and occupational and industrial characteristics and assess the effects on consumption. Seventy per cent of households in the bottom fifth of the earnings distribution hold insufficient assets to maintain current spending for more than one week. We compare the effectiveness of the UK's Coronavirus Job Retention Scheme and of Economic Impact Payments in the US. The EIPs are more effective at mitigating consumption reductions as they have full coverage, depend on household structure and are higher for low-income workers.
