创新型增长视角下的金融发展：综述及展望

传统经济增长理论分析框架下,金融系统只影响资本形成,并不创造社会财富,它对经济增长的作用只有水平效应而没有增长效应。新增长理论,尤其是熊彼特增长理论．突破了新古典增长理论关于技术进步的外生性假设,强调资本积累和创新是促进技术进步和经济增长的重要力量,这为研究金融体系对技术进步和经济增长的促进作用提供了全新视角。当前,中国金融发展现状与创新型增长要求之间存在一定程度的不相容性,需要在制度、政策和监管体系上不断完善与变革,逐步实现科技创新和金融发展的良性互动。     

Housing and credit market shocks: Exploring the role of rule-based Basel III counter-cyclical capital requirements

This paper examines the extent to which the Basel III bank capital regulation attenuates fluctuations in housing and credit markets and fosters financial and macroeconomic stability. We use a positive housing demand shock to mimic a housing market boom and a negative financial shock for credit squeeze and economic meltdown. The results show that the rule-based Basel III counter-cyclical capital requirement effectively attenuates fluctuations in housing and credit markets and prevents bubbles. In the case of a negative financial shock, it significantly reduces the magnitude of economic meltdown. Our analysis of the transition from Basel II to Basel III suggests that it is the counter-cyclical capital buffer that effectively mitigates the pro-cyclicality of its predecessor, while the impact of the conservative buffer is marginal. In contrast to the credit-to-GDP ratio, the optimal policy analysis suggests that the regulatory authority should adjust the capital requirement to changes in credit and output when implementing the counter-cyclical buffer. Future research could extend the study by comparing the effectiveness of the rule-based Basel III with other macroprudential tools in achieving financial and macroeconomic stability.     

金融结构、银行发展与经济增长

虽然关于金融发展与经济增长关系的研究已经著作颇丰,但金融结构和长期的经济增长之间是否存在相关关系,以及这种关系是通过何种机制实现的,却一直缺乏深入研究。通过实证分析,我们发现,金融结构的差异并不能有效地解释不同国家之间的经济增长差异。而进一步的分解分析还表明,在金融体系的内部,银行信贷对经济增长的作用要明显强于市场渠道,其基本的实现机制是:银行的发展增强了私人部门信贷的可获得性,同时银行具有事实上比股市更为重要的融资地位,从而在长期的经济增长中扮演了更为重要的角色。     

危机损失、经济复苏与金融结构比较——什么样的金融体系更能摆脱危机

本文从比较分析视角出发,研究在应对金融危机的过程中,不同的金融结构对经济增长的作用。我们利用57个国家从1960到2009年的面板数据检验了金融结构、金融发展水平与经济增长之间的相互联系。研究结果表明,只有当金融发展水平较高的经济体选择市场导向的金融结构时,才能降低金融危机的损失,提高经济复苏速度,而金融发展水平较低的经济体的最佳选择则是银行导向的金融结构。最后,本文结合中国的现实情况提出了相关的政策建议。     

金融发展、资本积累与内生增长:一个评述

本文以资本外溢AK内生增长模型为基础,对金融发展、资本积累与经济增长关系的理论研究和经验分析作了一个文献综述.理论研究表明:金融发展通过提高储蓄转化为资本比率、改善投资配置效率和改变储蓄率等途径促进资本积累和经济增长;金融发展与经济增长之间呈互相促进、互为因果的双向关系,并形成金融发达、经济高增长和金融欠发达、经济低增长的双重均衡.经验分析显示,金融发展与经济增长之间呈显著正相关关系,这证实了金融发展与内生增长理论的预测.     

Tipping the (Im)balance: Capital inflows,financial market structure,and banking crises

An emerging consensus among scholars and policy‐makers identifies foreign capital inflows as one of the primary determinants of banking crises in developed countries. We challenge this view by arguing that external imbalances are destabilizing only when banks face substantial competition from securities markets in the process of financial intermediation. We assemble a dataset of banking crises covering the advanced industrialized countries from 1976 to 2011 and find evidence of a conditional relationship between capital inflows, a well‐developed securities market, and the incidence of banking crises. We further explore the impact of capital inflows on banks’ actual risk taking as indicated by their capital adequacy levels and measures of insolvency risk. Our results demonstrate that prudential capital cushions tend to decline with the combination of capital inflows and prominent securities markets. We highlight the political decisions—often made during the early days of a country's financial development—that determine the relative prominence of banks vs. non‐bank financial institutions and conclude with policy recommendations.     

中国金融发展与农民收入增长

本文在对中国金融发展与农民收入增长进行制度和结构分析的基础上,运用1952—2003年的实际数据,对中国整体金融发展、农村金融发展与农民收入增长的关系进行了实证研究。结果显示:中国金融发展对农民收入增长具有显著的负效应,用金融发展与经济增长的正向作用关系直接替代金融发展与农民收入增长的关系,与我国经济发展的事实并不相符;同时,也验证了制度和结构分析所揭示的“中国金融发展中防止结构和功能失衡至关重要”的命题。在此基础上,文章就金融发展促进农民收入增长提出了简要的政策建议。     

The effects of elections on macroprudential policy

We provide evidence for a specific challenge in the design of macroprudential policy, namely political interference. Using panel data from 80 countries over the period of 1990–2016, we uncover the electoral cycles in macroprudential policy. We show that a loosening in macroprudential policy becomes more likely in the pre-election year, especially in countries with lower institutional quality. There is no evidence for the reversal of such actions in the post-election year. We also find that capital account openness, the history of macroprudential policy actions and inflation matter in determining the strength of electoral cycles in macroprudential policy, in addition to institutional quality. The electoral cycles are found to be stronger in countries that are financially less open, that relied less on macroprudential policy in the past, and that have lower inflation.     

A policy model to analyze macroprudential regulations and monetary policy

We construct a small‐open‐economy, new Keynesian dynamic stochastic general‐equilibrium model with real financial linkages to analyze the effects of financial shocks and macroprudential policies on the Canadian economy. The model incorporates rich interactions between the balance sheets of households, firms and banks, long‐term household and business debt, macroprudential policy instruments and nominal and real rigidities and is calibrated to match dynamics in Canadian macroeconomic and financial data. We study the transmission of monetary policy and financial and real shocks in the model economy and analyze the effectiveness of various policies in simultaneously achieving macroeconomic and financial stability. We find that, in terms of reducing household debt, more targeted tools such as loan‐to‐value regulations are the most effective and least costly, followed by bank capital regulations and monetary policy, respectively.     

Trade-offs between macroeconomic and financial stability objectives

Ten years after the 2008-09 global financial crisis, most advanced economies have recovered and global economic growth has taken hold. However, partly due to accommodative financial conditions, financial risks are on the rise while inflation remains subdued. This revives the debate on the role of monetary policy in containing financial risks. This paper provides a framework to investigate trade-offs between macroeconomic and financial stability when the central bank has a financial stability objective. Relying on a New Keynesian model with an endogenous financial bubble, our simulations suggest that a central bank attempting to “lean against the wind” may face trade-offs between inflation/output stability and financial stability. We therefore argue that the interest rate should be used for achieving traditional macroeconomic goals, and a second, macroprudential instrument should complement the policy rate to tackle financial risk accumulation.     

How does capital regulation react to monetary policy? New evidence on the risk-taking channel

Before the subprime crisis, financial stability was a microprudential issue addressed by capital regulation and unrelated to monetary policy. The financial crisis put this paradigm to the test and turned the spotlight on the relationship between financial stability and monetary policy. Hence, the following question arises: how does capital regulation react to monetary policy? This article seeks to answer this question. We analyze the link involving monetary policy and capital regulation through the risk-taking channel in Brazil. The findings suggest that banks react to monetary policy by changing the amount of loan provisions as well as the capital adequacy ratio (CAR). An important novelty of the study is the evidence that there is no trade-off between provisions and CAR, which are important tools used by banking supervisors. The key result of the article is that banks react to the macroeconomic environment differently from what is expected by banking supervision, i.e., there exists a paradox between the microprudential view and the macroprudential view. Thus, in terms of practical implication, a banking supervision strategy for financial stability must take into account the effects of monetary policy.     

收入水平、金融结构与国家技术创新研究

利用85个国家1989—2011年的跨国数据,实证检验不同收入水平下,金融结构对国家技术创新的影响差异。结果显示,高收入水平国家偏向于金融市场的金融结构更加有利于技术创新。基于新结构经济学理论思想,对该结果进行了解释：不同收入水平国家的创新结构不同,即自主研发和模仿创新的比例不同。从事自主研发和模仿创新的企业在风险特征、企业规模方面具有差异,这要求不同比例的金融市场和银行信贷与之匹配。由此,创新结构决定技术创新视角下的最优金融结构。因此,在特定发展阶段,存在与之相匹配的最能有效促进技术创新的金融结构。该结论强调了考虑发展阶段因素的必要性,为新结构经济学相关理论提供了新的实证证据,也具有明确的政策含义。     

中国金融规模、金融结构与经济增长——基于省区面板数据的实证研究

本文运用我国省区1999至2008年的面板数据,系统考察了金融规模、银行集中度、直接融资比例以及其他相关控制变量对各地区经济增长的作用和影响。通过运用固定效应模型、工具变量法以及动态面板数据模型,我们发现,目前金融规模扩张不利于经济增长,而改善金融结构,降低银行集中度,提高中小金融机构在银行业中所占的比重,会增加银行业内部的竞争,促进经济增长。直接融资对经济增长的作用不显著。我们还发现,改善我国所有制结构有利于经济增长,固定资产投资和对外贸易依然是拉动经济增长的重要因素。     

金融发展、研发创新与区域技术深化

基于内生增长理论,本文构建了金融发展、研发创新与区域技术深化的实证研究框架,以面板协整和空间计量经济学方法,通过空间误差修正模型(SpECM)和面板动态最小二乘回归(DOLS)实证检验了中国金融发展的规模与效率的区域创新效应。实证结果表明,总体而言,金融发展规模与效率具有显著的研发创新效应,但区域差异显著,西部地区省份相对滞后,分产业的金融发展效率的区域创新效应也与中、东部省份之间存在显著差异。空间误差修正模型的估计结果进一步说明金融发展的效率与规模存在明显的空间相关性和空间溢出效应。因此,以金融发展促进中西部省份服务业的产业技术升级显得尤为重要;加强区际及国际贸易联系、促进省份层面技术引进与研发创新、共享技术空间溢出效应是缩小区域发展差异,实现区域经济协调发展的有效途径。     

Financial frictions and stabilization policies

After the financial crisis of 2007, in many economies, public and private debt have moved in opposite directions, as opposed to pre-2007 evidence. Private deleverage and public debt build-up may affect the recovery path of countries after a recession. In a new Keynesian model with financial frictions, we show that when the economy is hit by a credit risk shock, the negative correlation arising between public and private debt amplifies the response of GDP. In our setup, the traditional monetary-fiscal policy mix is not enough to offset this private-public debt mechanism and therefore bring back economic stability. When macroprudential policy is part of the policy mix, the private-public debt channel can be broken. Interestingly, depending on the macroprudential instrument, a trade-off may arise between private debt and output stabilization.     

The causal relationship between financial development and economic growth in Africa

ABSTRACT

Previous empirical studies on the causal relationship between financial development and economic growth are not instructive given their failure to unearth the causality trend across the different time periods. Using a more recently developed and robust indicator of financial development, we revisit the causal relationship between financial development and economic growth within the framework of a frequency-domain spectral causality technique which allows the causality to vary across time. Using data from 47 African countries over the period 1980–2016, our findings largely suggest that, even though there is some evidence of demand-following, supply-leading and feedback hypotheses, for most part, we find strong support of neutrality hypothesis. Thus, financial development and economic growth at most frequency levels evolve independently. We infer that caution must be exercised in making general conclusions about the causal nexus between financial development and economic growth.     

Assessing the macroeconomic impact of alternative macroprudential policies

This article assesses effects on the wider economy and overall costs and benefits of two alternative macroprudential policies - loan-to-value ratios on mortgage lending and variable bank capital adequacy targets. It also traces the potential effects of such policies if introduced prior to the subprime crisis. The work is performed within the National Institute Global Econometric Model, with a focus on Germany, Italy and the UK. Detailed banking sectors and addition of a macroprudential block to our model enable effects of policies to be captured. A systemic risk index tracks the likelihood of the occurrence of a banking crisis and establishes thresholds at which macroprudential policies should be activated by the authorities. Capital adequacy impacts the economy by acting on the spread between borrowing and lending of corporates and households, while loan-to-value transmits through its impact on the housing market. We find generally loan-to-value policy has a lesser effect than capital adequacy on crisis probabilities and net benefits, but there is considerable cross country variation. We show that the introduction of macroprudential policy prior to the crisis would have led to improvement in a number of key macroeconomic measures and might thus have reduced the incidence of the crisis.     

我国收入不平等、金融发展和消费需求波动的实证研究:1978～2001

本文考察了收入不平等与总消费需求变动之间的联系,在高收入地区,不平等程度越大似乎消费需求波动越大,而在低收入地区,收入不平等越大,消费需求波动反而较小。本文找到证据表明金融发展水平能有助于解释为什么收入分配在高收入和低收入地区中影响消费需求的短期波动是不同的,本文的政策含义是,加快低收入地区如中西部的经济和金融发展步伐,加大金融发展相机调整的力度。     

Does bank shareholding impact corporate innovation? Evidence from China

Corporate innovation is an engine of economic development, while bank shareholding is the phenomenon of having a bank as a shareholder. Their relationship, however, has been underexamined. We provide the first study on the direct impact of bank shareholding on corporate innovation. Using patents granted to Chinese firms from 1999 to 2013, our findings suggest that bank shareholding significantly contributes to corporate innovation. Additional analysis suggests that easing financial constraints can facilitate the positive impacts of bank shareholding on corporate innovation. We also find that bank shareholding works better when firms have effective external monitoring and when they are nonstate-owned firms with nonstate-owned banks as shareholders. We contribute to the literature by showing that (1) despite the restrictions some countries impose on bank shareholding, allowing it could be a good economic policy for promoting corporate innovation, and (2) successful corporate innovation requires proper monitoring and incentives.     

What impact do differences in financial structure have on the macro effects of bank capital requirements in the United States and Australia?

We investigate the influence of jurisdictional differences in financial structure on the economic consequences of bank capital regulation. We use two disaggregated financial computable general equilibrium models to compare the impacts of identical increases in bank capital adequacy ratios in the U.S. and Australia. In both models, this raises bank equity financing shares, and lowers banks’ risk-weighted asset holdings. Thereafter however, differences in financial structure drive contrasting outcomes: in the U.S., average costs of capital fall, stimulating real investment, while we find the opposite outcome for Australia. We attribute this to differences in the structure of bank assets (U.S. banks hold more risk-free assets) and the importance of banks as intermediaries (bank finance is more important to capital formation in Australia). This may explain why capital regulations encompass non-banks in the U.S. but not Australia.
