初始财富格局与居民可支配收入比重下降趋势

近年来,我国居民收入在国民可支配收入中的占比不断下降,理解这一问题的成因,是制定扩大内需、调整经济结构和完善收入分配制度等政策措施的基础。本文认为,尽管我国改革初始的财富格局(国有资产、土地、资源等集中在国家)对GDP增长没有影响,但对收入分配格局及变化趋势则有至关重要的影响。本文利用1997～2007年资金流量表,通过利息收入、土地出让金、国有企业利润等数据,对居民、企业和政府实际可支配收入项目进行了调整,并相应地还原了企业、政府和居民的可支配收入中资产收益的作用。结果发现,资产性收益对国民收入分配格局影响显著,也说明了财富格局比劳动力报酬更有解释力。因此,要从根本上扭转居民可支配收入比重不断下降的趋势,就必须改变目前国有财富占比过高的分配格局。     

The Allocation of Aggregate Risk,Secondary Market Trades,and Financial Boom–Bust Cycles

The financial crisis of 2007–08 started with the collapse of the market for collateralized debt obligations backed by subprime mortgages. In this paper we present a mechanism aimed at explaining how a freeze in a secondary debt market can be amplified and propagated to the real economy, and thereby cause a recession. Moreover, we show why such a process is likely to be especially strong after a prolonged expansion based on the growth of consumer credit and endogenously low risk premia. Hence, our model offers a new perspective on the links between the real and financial sectors, and we show how it can help make sense of several macro‐economic features of the 2001–09 period. The key elements of the model are heterogeneity across agents in terms of risk tolerance, a financial sector that allocates systematic risk efficiently across agents, and real decisions that depend on the price of risk.     

Wealth Effects on Self-Insurance and Self-Protection against Monetary and Nonmonetary Losses

This paper considers the wealth effects on self-insurance and self-protection activities against possible losses of monetary wealth such as properties and nonmonetary wealth such as health. Increased initial income or monetary wealth decreases the demand for self-insurance against monetary wealth loss under the decreasing absolute risk aversion assumption, and has an ambiguous effect on self-protection. However, increased initial monetary wealth increases both self-insurance and self-protection against health loss, explaining empirical trends, if wealth and health are complements. When multiple self-insurance activities against both types of losses are considered, the effect of an increase in initial monetary wealth on self-insurance against health loss remains the same, but the effect on self-insurance against wealth loss depends on the preferences.

Wealth effects of convertible-bond and warrant-bond offerings: a meta-analysis

The literature on wealth effects associated with the announcements of convertible-bond and warrant-bond offerings is reviewed. The findings of 35 event studies, which include 84 sub-samples and 6310 announcements, are analysed using meta-analysis. We find a mean cumulative abnormal return of?1.14% for convertibles compared with?0.02% for warrant bonds, the significant difference confirming a relative advantage for warrant bonds. Abnormal returns for hybrid securities issued in the USA are significantly more negative than those issued in other countries. In addition, issuing hybrid securities to refund debt does not seem to be favoured by investors. Finally, several factors identified as important by theory or in prior research are not significant within our cross-study models, suggesting that more evidence is needed to confirm whether they are robust.     

Assessing the Macroeconomic Effects of LTROs during the Great Recession

In response to the 2008–2009 crisis, faced with distressed financial intermediaries, the European Central Bank (ECB) embarked in longer term refinancing operations (LTROs) with full allotment. Using an estimated DSGE model with a frictional banking sector, we find that such liquidity injections have played a key role in averting a major credit crunch. A counterfactual analysis suggests that, absent these nonconventional measures, output, consumption, investment, and the GDP deflator would have been 2.5%, 0.5%, 9.7%, and 0.5% lower on average over 2009, respectively.     

金融素养、家庭财富与家庭创业决策

本文利用2015年中国家庭金融调查(CHFS)数据,分析了金融素养、家庭财富与家庭创业决策三者之间的关系。整体上,金融素养的提高显著增加了家庭参与创业的可能性,但家庭参与创业面临着财富约束效应;而金融素养对家庭财富具有替代作用,提高金融素养有效缓解了家庭的财富约束效应,促进家庭参与创业。同时,研究发现家庭财富对家庭创业决策的影响并不存在明显的城乡差异,但金融素养更能缓解农村家庭创业所面临的财富约束效应。另外,提高金融素养能有效缓解家庭的信贷约束,增加其风险偏好,间接地促进创业。     

Shadow Banks and Macroeconomic Instability

We develop a macroeconomic model in which commercial banks can offload risky loans to a “shadow” banking sector, and financial intermediaries trade in securitized assets. The model can account both for the business cycle comovement between output, traditional bank, and shadow bank credit, and for the behavior of macroeconomic variables in a liquidity crisis centered on shadow banks. We find that following a liquidity shock, stabilization policy aimed solely at the market in securitized assets is relatively ineffective.     

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.     

State‐Dependent Transmission of Monetary Policy in the Euro Area

We estimate a logit mixture vector autoregressive model describing monetary policy transmission in the euro area over the period 1999–2015. In contrast to other classes of nonlinear vector autoregressive models, regime affiliation is neither strictly binary, nor binary with a transition period, and based on multiple variables. We show that monetary policy transmission in the euro area can be described as a mixture of two states. In both states, output and prices are found to decrease after contractionary monetary policy shocks. However, the effects of monetary policy are less enduring in the “crisis state.”     

我国股市财富效应对居民消费影响的实证检验——基于生命周期—持久收入理论扩展模型的新视角

基于生命周期-持久收入(LC-PIH)理论,本文建立居民收入、消费支出、股市市值和购房支出几个变量之间的实证检验模型,以研究我国股市的财富效应。选取季度和月度频率数据,测算我国2003~2018年全口径居民消费和2013~2018年乘用车消费的股市财富效应,实证结果发现全口径居民消费主要受收入的影响,股市的财富效应不显著,检验结果符合持久收入说;乘用车消费除受收入的影响之外,股市的财富效应也显著。基于实证结果,并结合发达国家较为普遍存在的财富效应,提出三点建议:一是稳步提高居民可支配收入,是促进我国消费平稳增长、发挥消费拉动经济增长基础性作用的根本;二是要发挥出股市在消费中的财富效应,需改变我国股市长期存在的牛短熊长困境;三是应进一步提高我国居民通过养老金和企业年金等间接渠道参与股市的比重,使养老金、企业年金等长期资金与资本市场形成良性互动。     

Credit Indicators as Predictors of Economic Activity: A Real‐Time VAR Analysis

Using readily available indicators of the profitability, price, and availability of credit—the term spread, junk‐bond spread, and banks’ “willingness to lend” as reported by the Federal Reserve—we show that it is possible to significantly improve on the real‐time output and employment predictions of forecasting professionals at the medium‐run horizons that are most relevant to policymakers and private decision makers. Key to this improvement is a flexible state–space model of data revisions. The willingness‐to‐lend variable is the best real‐time predictor of GDP growth. For forecasting job growth, all three credit indicators prove helpful.     

An Inflation‐Predicting Measure of the Output Gap in the Euro Area

Using a small Bayesian dynamic factor model of the euro area, we estimate the deviations of output from its trend that are consistent with the behavior of inflation. We label these deviations the output gap. In order to pin down the features of the model, we evaluate the accuracy of real‐time inflation forecasts from different model specifications. The version that forecasts inflation best implies that after the 2011 sovereign debt crisis, the output gap in the euro area has been much larger than the official estimates. Versions featuring a secular stagnation‐like slowdown in trend growth, and hence a small output gap after 2011, do not adequately capture the inflation developments.     

Asset Write‐downs: Evidence from 2001–2008

Accounting for asset write‐downs has received substantial media attention throughout the Global Financial Crisis and has been the subject of academic debate and numerous accounting regulations during the past three decades. This study provides evidence of the magnitude and frequency of quarterly asset write‐down activities for a sample of US firms between 2001 and 2008 and examines whether reported asset write‐downs mirror market and economic indicators during the sample period.     

Macroeconomic Effects of Government Spending: The Great Recession was (Really) Different

We estimate the effect of government spending shocks on the U.S. economy with a time‐varying parameter vector autoregression. The recent Great Recession period appears to be characterized by uniquely large impulse responses of output to fiscal shocks. Moreover, the particularity of this period is underlined by highly unusual responses of several other variables. The pattern of fiscal shock responses neither completely fits the predictions of the New Keynesian model of an economy subject to the zero lower bound on nominal interest rates, nor does it suggest regular variation of fiscal policy effects depending on the state of the business cycle. Rather, the Great Recession period seems special in that government spending shocks had a strongly negative effect on the spread between corporate and government bond yields and a strongly positive effect on consumer confidence and private consumption spending.
