双支柱调控的金融稳定效应研究*

本文基于全球42个主要经济体1991—2016年的面板数据，系统考察了双支柱政策框架的金融稳定效应。实证结果表明：（1）货币政策和宏观审慎政策在抑制家庭信贷增长上具有显著作用，双支柱政策在缓解金融风险顺周期性上具有显著的金融稳定效应；（2）盯住贷款的宏观审慎工具和针对借款人、贷款人的宏观审慎组合具有更为显著的金融稳定效应；（3）新兴经济体的货币政策在抑制家庭信贷扩张上的作用不显著，但其宏观审慎政策的金融稳定效应相较发达经济体更为显著，发达经济体双支柱政策的金融稳定效应总体显著，其中货币政策效应更为突出；（4）发达经济体的货币政策效应在下行周期优于上行周期，宏观审慎政策及其与货币政策的交互效应在上行周期优于下行周期；（5）只有个别宏观审慎工具会对失业率、消费和物价产生微弱的负效应。     

Terrorism and international economic policy

We add to the ongoing discussion regarding the policy consequences of terrorism by analyzing the effect of terrorism on international economic policy for a panel of 170 countries between 1970 and 2016. We find that countries resort to less liberal international economic policies when facing the threat of terrorism. This effect is especially relevant to smaller (less populated) countries. Our main finding is robust to an instrumental-variable approach. We argue that governments pursue less liberal international economic policies in response to terrorism to interrupt the organization and financing of terrorism, limit capital flight, stabilize public finances and signal political resolve.     

实现2035年发展目标的潜在增长率*

党的十九届五中全会提出了到2035年人均GDP达到中等发达国家水平的远景目标，因此测算和回答能否和如何如期实现该目标，对于我国实现第二个百年奋斗目标和坚持“四个自信”具有重要的意义。为此，本文根据跨越和陷入“中等收入陷阱”经济体的发展经验，对2021—2035年我国潜在增长率变化进行了测算。一是参照跨越和陷入“中等收入陷阱”经济体在我国相同发展阶段时各主要生产要素的变化，模拟设定我国未来各主要生产要素的增长率；二是通过运用附加人力资本的增长核算模型测算基准、乐观和悲观三种不同情境下未来我国经济的潜在增长率，验证我国2035年发展目标实现的可能性；三是依据主要要素对潜在增长率的贡献度，提出我国如期实现2035年发展目标的相应政策建议。     

Financial returns to collecting rare political economy books

Rare books of political economy are eminently collectable. Using historical prices, I employ hedonic regressions to estimate financial returns to collecting the works of ten eminent political economists and develop a price index for this corpus of collectables. For the observation period 1975–2019, I find that in those 45 years investing in rare political economy books yielded an average annual real rate of return of 2.8%, which is well in line with the returns to collecting rare books of classical literature. Compared with other collectibles such as fine art, investing in rare books turns out to be financially more profitable.     

Unconventional monetary policy announcements and information shocks in the U.S.

We study unconventional policy shocks and information shocks associated with central bank announcements in the U.S. While unconventional policy shocks capture the direct influence of announced monetary policy actions, information shocks are associated with central bank information conveyed with the announcement. To disentangle these two types of shocks, we impose sign restrictions on high frequency changes in interest rates and stock prices around announcements. We find that information shocks lead to persistent declines in the 10-year government bond yield, whereas the actual unconventional policy shock induces only small interest rate responses. We also find that expansionary output effects of unconventional monetary policy are to some extent counteracted by the information shock.     

Dynamics of the Market for Corporate Tax‐Avoidance Advice*

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.     

Overcoming the “Solow paradox”: Tariff reduction and productivity growth of Chinese ICT firms

This paper examines the phenomenon of the “Solow paradox” in China using the Annual Survey of Industrial Production database and the China Customs Records dataset from 1998 to 2007. We find that China likely fell into the Solow paradox in the period 1998–2002, but the total factor productivity of information and communication technology (ICT) enterprises has achieved rapid growth since 2003. Accession to the World Trade Organization is the key reason for China to overcome the Solow paradox, that is, input tariff reduction significantly promoted the productivity of ICT firms. A series of validity and robustness checks confirmed the results. Mechanism analysis shows that input liberalization promotes the productivity of ICT firms through optimizing factor structure, importing more and high-quality inputs, and increasing research and development investment. The conclusions provide strong empirical evidence for developing countries to overcome the Solow paradox through trade liberalization.     

纳税信用评级结果披露与研发投入

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。
