信贷增长如何影响中国的收入和财富不平等

本文基于中国家庭追踪调查(CFPS)数据考察了信贷增长对中国家庭收入和财富不平等的影响。整体而言，信贷增长可以缩小家庭收入不平等，主要作用机制是信贷增长通过提高中低收入群体的劳动收入和单位时薪以缩小劳动收入不平等。同时，文献中所发现的信贷增长可能恶化收入不平等的机制——扩大家庭间非货币金融资产差距，在我国表现并不明显，原因在于中国家庭的非货币金融资产比例较低，这一点对于高收入家庭也不例外，且大部分家庭难以从金融资产交易中获利。信贷增长带来了各个收入组的房屋价值上涨，但高收入家庭房产价值上涨的幅度高于中低收入家庭，因此房价上涨扩大了不同收入家庭所持有的房产价值差异。考虑到家庭调查数据往往对高收入家庭的收入和财产覆盖不完整，上述结论可能低估了信贷增长对极少数高收入家庭收入和资产的影响。本文有助于更好地理解我国信贷增长对收入分配问题的影响，为相关政策制定提供了一定启示。     

Does Monetary Policy Affect Income Inequality in the Euro Area?

This paper examines how the ECB's expansionary monetary policy affects income inequality in 10 euro area countries over the period 1999–2014. We distinguish two channels—labor-market and financial—through which monetary policy can have distributional effects. The labor-market channel is captured by wages and employment and the financial channel by asset prices and returns. We find that expansionary monetary policy in the euro area reduces income inequality, especially in the periphery countries. The labor-market channel enhances the equalizing effect: monetary expansion reduces income inequality stronger by raising wages and employment. There is limited evidence for the financial channel.     

Innocent Bystanders? Monetary policy and inequality

We study the effects of monetary policy shocks on—and their historical contribution to—consumption and income inequality in the United States since 1980 as measured by the Consumer Expenditure Survey. Contractionary monetary policy systematically increases inequality in labor earnings, total income, consumption and total expenditures. Furthermore, monetary policy shocks account for a non-trivial component of the historical cyclical variation in income and consumption inequality. Using detailed micro-level data on income and consumption, we document some of the different channels via which monetary policy shocks affect inequality, as well as how these channels depend on the nature of the change in monetary policy.     

Monetary Policy and Inequality

We analyze the distributional effects of monetary policy on income, wealth, and consumption. We use administrative household-level data covering the entire population in Denmark over the period 1987 to 2014 and exploit a long-standing currency peg as a source of exogenous variation in monetary policy. We find that gains from softer monetary policy in terms of income, wealth, and consumption are monotonically increasing in ex ante income. The distributional effects reflect systematic differences in exposure to the various channels of monetary policy, especially nonlabor channels (e.g., leverage and risky assets). Our estimates imply that softer monetary policy increases income inequality.     

Equity market and the transmission channels of monetary policy: Before and after the zero lower bound

We examine the effectiveness of the interest rate channel and the credit channel of monetary policy before and after the zero lower bound (ZLB), using intraday stock returns. We construct a number of industry-specific and firm-specific indicators to capture the sensitivity of firms' demand to interest rates (interest rate channel) and firms' financial constraints (credit channel). We find that the transmission of monetary policy has shifted across both periods. Conventional monetary policy works through both the neoclassical interest rate channel and the credit channel, while unconventional policy is propagated primarily via the credit channel which became even more effective at the ZLB. Before the ZLB the transmission channels operate primarily through target rate shocks rather than forward guidance announcements, whereas both forward guidance and large scale asset purchases were equally important for the credit channel at the ZLB. We also find strong evidence that transmission channels are asymmetric depending on the state of the stock market (bull/bear, tighter/easier credit conditions, high/low volatility), and the type of policy surprises (positive/negative). Our findings are robust with respect to a number of model extensions and alternative specifications.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

International monetary policy transmission through banks in small open economies

This paper studies the international transmission of monetary policy through banks in small open economies using the examples of Switzerland and Canada. We assess the inward transmission of foreign monetary policy for Switzerland and the outward transmission of domestic monetary policy for Canada. In both country cases, we focus on the international bank lending and the international portfolio channel, which make opposing predictions about how monetary policy transmits internationally through banks. Our results on the inward transmission of foreign monetary policy through banks in Switzerland are consistent with a role for the international portfolio channel, but we find no evidence for the traditional international bank lending channel. The results on the outward transmission of domestic monetary policy in Canada suggest that foreign lending by Canadian banks is affected through both channels, which work as predicted and largely balance each other.     

居民风险偏好与中国货币政策的宏观经济效应——基于DSGE模型的数量分析

当前,我国宏观经济形势复杂多变,货币政策实施效果的影响因素随之呈现多样化特征。在此背景下,本文试图以风险偏好为研究视角,对我国居民风险偏好水平变动与货币政策宏观经济效应之间的关系进行分析。本文以标准新凯恩斯模型为基础,构造符合我国宏观经济现实特征的DSGE(动态随机一般均衡)模型,并对转型时期的最优混合型货币政策规则进行研究;为进一步强调货币在中国宏观经济波动中所扮演的重要角色,模型中引入消费和实际货币余额不可分的跨期效用函数形式。研究结果表明:(1)包含名义货币增长的混合型泰勒规则拟合我国转型时期的货币政策规则效果最佳,因此货币供应量仍是重要的政策工具;(2)与可分性模型相比,不可分模型拟合我国宏观经济现实特征的效果更优。在不可分效用函数下,与货币供应量相关的实际货币余额将影响经济的产出缺口和通货膨胀,使得居民风险偏好成为决定货币政策效果的重要因素。具体而言,当居民风险偏好水平上升时,货币政策对我国宏观经济波动的影响随之增强。因此,在选择货币政策实施时点上,应充分考虑市场中的风险偏好情况,从而更好地发挥货币政策调控宏观经济的职能。

Household Debt Overhang and Transmission of Monetary Policy

We investigate how the level of household indebtedness affects the monetary transmission mechanism in the U.S. economy. Using state‐dependent local projection methods, we find that the effects of monetary policy are less powerful during periods of high household debt. In particular, the impact of monetary policy shocks is smaller on GDP, consumption, residential investment, house prices, and household debt during a high‐debt state. We then build a partial equilibrium model of borrower households with financial constraints to rationalize these facts. The model points to the weakening of the home equity loan channel as a possible reason for the decline in monetary policy effectiveness when initial debt levels are high.     

A Further Look at the Propagation of Monetary Policy Shocks in HANK

We provide quantitative guidance on whether and to what extent different elements of Heterogeneous Agent New Keynesian (HANK) models amplify or dampen the response of aggregate consumption to a monetary policy shock. We emphasize four findings. First, the introduction of capital adjustment costs does not affect the aggregate response, but does change the transmission mechanism so that a larger share of indirect effects originates from equity prices rather than from labor income. Second, incorporating estimated unequal incidence functions for aggregate labor income fluctuations leads to either amplification or dampening, depending on the data and estimation methods. Third, distribution rules for monopoly profits that allocate a larger share to liquid assets lead to greater amplification. Fourth, assumptions about the fiscal reaction to a monetary policy shock have a stronger effect on the aggregate consumption response than any of the other three elements.     

The channels of monetary policy triggered by central bank actions and statements in the Australian equity market

Owing to the discrete disclosure practices of the Reserve Bank of Australia, this paper provides new evidence on the channels of monetary policy triggered by central bank actions (monetary policy announcements) and statements (explanatory minutes releases), in the Australian equity market. Both monetary policy announcements and explanatory minutes releases are shown to have a significant and comparable impact on the returns and volatility of the Australian equity market. Further, distinct from US and European studies that find strong evidence of the interest rate, bank loan and balance sheet channels and no evidence of the exchange rate channel following central bank actions, this paper finds that monetary policy impacts the Australian equity market via the exchange rate, interest rate and bank loan channels of monetary policy, with only weak evidence of the balance sheet channel of monetary policy. These channels are found to be operating irrespective of the trigger (monetary policy announcements or explanatory minutes releases), though results are somewhat weaker when examining the explanatory minutes releases. These results have important implications for central bank officials and financial market participants alike: by confirming a comparable avenue to affect monetary policy; and providing an explication of its impact on the Australian equity market.     

Estimating the impact of monetary policy on income inequality in China

The article estimates the impact of monetary policy on income inequality in China. The empirical time series analysis finds that a battery of monetary indicators and the change in the unemployment rate lead to increases in the Gini coefficient. But only unemployment is statistically significant. The lack of significance of the monetary indicators is robust to running different econometric models using nominal output as an alternative to unemployment. Unemployment’s impact on income inequality is robust to considering a fiscal policy proxy alongside inflation in the benchmark equation.     

物价与货币政策调控最优契合的实证研究

本文从货币渠道和信贷渠道对物价与货币政策的关系进行实证检验。结果表明,货币政策与物价水平之间存在稳定的均衡关系,但是货币政策存在滞后性,货币供应量M2的滞后期约为2个月,金融机构各项贷款规模的滞后期约为4个月,并基于此对货币政策调控提出相关建议。     

住房价格、金融稳定与宏观审慎政策

本文通过建立包含异质性家庭、异质性厂商和金融机构的DSGE模型,分析对预期房价作出反应的货币政策和宏观审慎政策的传导机制和政策效果,研究不同政策的选择和协调问题。研究发现,首先,由于政策的作用范围不同,不同政策会对金融稳定和经济稳定产生不同影响。对预期房价作出反应的货币政策能够抑制住房需求和信贷供给,但也会抑制消费需求和产出;而对预期房价作出反应的逆周期LTV政策和逆周期资本充足率政策在应对房价波动导致的金融稳定问题时更加有的放矢。其次,外生冲击的来源会影响政策的选择和协调——当经济波动来源于需求冲击时,固定LTV政策搭配逆周期资本充足率的宏观审慎政策、不对预期房价作出反应的货币政策表现最优;当经济波动来源于供给冲击时,固定LTV政策搭配逆周期资本充足率的宏观审慎政策、对预期房价作出反应的货币政策表现最优。     

Monetary policy, taxes, and the business cycle

This paper analyzes the interaction of inflation with the tax code and its contribution to aggregate fluctuations. We find significant effects operating through the tax on realized nominal capital gains. A tax on nominal bond income magnifies these effects. Our innovation is to combine monetary policy shocks with non-indexed taxes in a model where the central bank implements policy using an interest rate rule. Monetary policy had important effects on the behavior of the business cycle before 1980 because policymakers did not exert effective control over inflation. Monetary policy reform around 1980 led to better control, and with more stable inflation, the effect of the interaction between monetary policy and the nominal capital gains tax has become negligible.     

Monetary policy,bank competition and regional credit cycles: Evidence from a quasi-natural experiment

This paper examines how competition in the banking sector affects the transmission of monetary policy and the variation of credit expansion across regions in the United States. Using the U.S. branching deregulation between 1994 to 2008 as an exogenous change in banks’ competition, we analyze how bank competition affects monetary policy transmission through the bank lending channel. The results show that competition strengthens the impact of monetary policy on bank loan supply. We then show that states with a more deregulated banking sector were more affected by monetary conditions in the years leading to the Great Recession. Specifically, the effect of loose monetary conditions on the expansion of households’ debt was stronger in states that had fewer bank branching restrictions. The results suggest that variations in the level of bank competition may have amplified regional asymmetries in the years leading to the Great Recession.     

Consolidation in banking and the lending channel of monetary transmission: Evidence from Asia and Latin America

This paper examines the relationship between increased consolidation in banking and monetary policy transmission in eighteen Asian and Latin American economies, using bank-level data from 1996 to 2006. Our results provide consistent evidence that as concentration in banking increases, the bank lending channel is weakened, leading the monetary policy transmission mechanism to be less effective. We also investigate how this relationship between concentration and the strength of the lending channel depends on bank-specific characteristics. Using bank-level balance sheet and income statement data allows us, first, to better identify the effects of banking consolidation on the supply-side bank lending channel from those of the demand-side interest rate channel, and second, to test for any systematic differences in the impact of consolidation on monetary policy transmission across banks of different size and financial strength. We also discuss potential explanations for and policy implications of the main findings of this paper.     

货币政策和银行风险承担：一种非线性关系

宽松的货币政策会通过估值、收入和现金流机制,追逐收益机制以及中央银行沟通和反应机制等渠道增加银行风险承担,通过风险转移机制降低银行风险承担,从而导致货币政策与银行风险承担之间可能存在复杂的非线性关系。本文使用面板阈值模型,基于我国银行业数据研究了货币政策对银行风险承担的影响,发现我国货币政策对银行风险承担的影响存在门限效应,即货币政策对银行风险承担的影响取决于货币政策基准利率偏离泰勒规则利率的程度。当这种偏离小于门限值时,宽松货币政策会增加银行风险承担;当这种偏离大于门限值时,宽松货币政策会降低银行风险承担。本文研究对更好地理解我国货币政策对银行风险承担及金融稳定的影响有一定参考意义。     

Aggregate Implications of Heterogeneous Households in a Sticky‐Price Model

This paper analyzes the role of heterogeneous households in propagating shocks over the business cycle by generalizing a basic sticky‐price model to allow for imperfect risk sharing between households that differ in labor incomes. I show that imperfectly insured household consumption distorts household incentive to supply labor hours through an idiosyncratic income effect, which in turn generates strategic complementarities in price setting and thus amplifies business cycle fluctuations. This mechanism diminishes the role of nominal rigidities and makes sticky‐price models more consistent with microeconomic evidence on the frequency of price changes.
