How Does Monetary Policy Affect Income andWealth Inequality? Evidence from Quantitative
Easing in the Euro Area
Michele Lenza Jirka Slacalek
European Central Bank
Challenges in Understanding the Monetary Transmission Mechanism
Warsaw, 22 March 2019
The views expressed in this presentation are those of the authors and do not necessarily
reflect the views of the European Central Bank and the Eurosystem.
Lenza and Slacalek (ECB) EABCN Conference 22 March 2019 1 / 20
Motivation and main results
Recent (academic and public) debate on impact ofquantitative easing on inequality
Widely diverging perspectives on how QE may affect inequality (see alsoColciago, Samarina and de Haan, 2018):
I QE boosted asset prices and financial wealth, it “made the rich richer’’(eg FT, Oct 21, 2014)
I However, QE also boosted house prices: these gains are more widely spread,as homeowners more evenly distributed than stock-holders
I Expansionary mon policy reduces unempl, benefits poorer households most
ECB has since 2015 undertaken quantitative easing (QE)(“Asset Purchase Programmes” - APP)

Motivation and main results
Question and method
What are the effects of QE on inequality in the euro area?
Step 1: Aggregate data
Multi-country VAR with, among other things, aggregate unemployment,wages and asset prices ⇒ Impulse responses to QE shock
Step 2: Household-level data, Household Finance and ConsumptionSurvey
Transpose IRFs over household-level data ⇒ Estimate effects of QE on
wealth and income inequality (Gini index)
Income (composition and earning heterogeneity channel); Wealth(composition channel)

Main Results
One year after the occurrence of the QE shock:
QE reduces income inequality⇒ Key role of the earnings heterogeneity channel (extensive margin,transition out of unemployment)
Wealth inequality is largely unchanged (in background slidestoday)

QE ”scenario”
1 Identify exogenous asset purchase shock with zero and signrestrictions (Baumeister and Benati, 2013; Arias et al., 2017)
Expansionary QE (APP) shock on impact:I Leaves short-term interest rate unchangedI Decreases long-term interest rates ⇒ Decreases term spreadI Increases real GDP
2 Offset response of EA policy rate via series of standard MP shocks
I Standard MP did not react to offset effects of asset purchases (policyrate remained at lower bound)
I Standard MP shock identified via standard zero (Choleski) restrictions

Unemployment simulation—Extensive margin [Ampudia et al. (2016)]
1. Who becomes employed? Probit model
Country (c)-specific at individual level (not Hh):
Pr(Y = 1|X = x) = Φ(x ′c,i βc)
Y empl status, X demographics (gender, edctn, age, mar status, chldrn)
Collect fitted probability to be employed: Yc,i
Simulation: those with an higher Yc,i are more likely to become employed∑newly employed people = aggregate decline in unempl implied by VAR
2. Which wages do newly employed get? Estimate unobserved wages
Income of the newly employed increases as implied by wage regression(Heckman): wage instead of (lower) unempl benefits
The wage is based on demographic characteristics

Robustness checks on income inequality
Main question: what about the dynamics of financial income?
Issue: lack of good data on financial incomeI Proxy 1: profits for the euro areaI Proxy 2: net property income for the four countries
Local linear projections (Jorda, 2005):How do these variables respond to QE shock?
I ProfitsI Net property income
Using the two proxies of financial income, Gini drops from 43.07 to42.89 (as opposed to 42.86 in the baseline). The result on incomeinequality is unchanged.

Net interest rate exposure—Auclert (2017)Net interest rate exposure = maturing assets - maturing liabilities
Maturing assets = 25% of value of mutual funds, bonds, shares, managedaccounts, money owed to households, other assets + 100% of deposits
Maturing liabilities = 100% outstanding balance of adjustable-rate mortgages +100% outstanding balance of other non-collateralized debt
