The impact of macroeconomic factors on income inequality: Evidence from the BRICS

In this paper we investigate how the evolution of income growth, real interest rates, and inflation have driven income inequality across a variety of countries with particular focus on the BRICS economies (Brazil, Russia, India, China, and South Africa) during the period 2001 to 2015. Our work suggests that, when central banks of the BRICS economies use monetary policy for macroeconomic stabilization, they need to consider the impact monetary policy changes have on the distribution of income in their nations. Our estimates reveal that the unintended consequence of policies that induce economic growth and higher prices is higher income inequality. We find that the positive relationship between the three macroeconomic variables and income inequality for the BRICS economies is stronger during the post-2008 period.     

Indexing Out of Poverty? Fiscal Drag and Benefit Erosion in Cross-National Perspective

We assess how tax-benefit policy developments in 2001–11 affected the household income distribution in seven EU countries. We use the standard microsimulation-based decomposition method, separating further the effect of structural policy changes and the uprating of monetary parameters, which allows us to measure the extent of fiscal drag and benefit erosion in practice. The results show that despite different fiscal effects, policies overall mostly reduced poverty and inequality and both types of policy developments had sizeable effects on the income distribution. We also find that the uprating of monetary parameters not only had a positive effect on household incomes, meaning fiscal drag and benefit erosion were avoided, but generally also contributed more to poverty and inequality reduction than structural policy reforms.     

Effects of monetary and government spending policy on economic inequality

Using detailed micro-level income and expenditure data, we study the effects of monetary and government spending policy shocks on income and expenditure inequality in the US from 1990 to 2018. We find that expansionary monetary and government spending policy shocks systematically decrease income, disposable income and expenditure inequality. There is evidence of time variation on the effects and monetary policy and transfer payment shocks. Various impulse responses suggest that the impacts of the policy shocks increase during and after the Great Recession. The responses of income and expenditures of households at different percentiles suggest that expansionary monetary and government spending policy have a larger positive impact on households with low income and expenditures relative to those at the top of the distribution. We do not find evidence of the significant impact of Quantitative Easing policies on income inequality, however, expenditure inequality appear to increase due to the policies.     

The microfoundation of macroeconomic populism: The effects of economic inequality on public inflation aversion

Previous work on the politics of monetary policy has focused on the role of distributive motives stemming from individual characteristics such as income or factoral/sectoral interests in citizens' formation of monetary policy preferences. However, the existing literature has paid little attention to how a country's overall distributive context, namely, its level of economic inequality, affects citizens' preferences vis-à-vis price stability and employment. This article argues that as inequality pushes more citizens below a society's average income, there is more demand for redistribution through higher employment and increased fiscal spending, each of which can be better supported by expansionary monetary policy. This means that inequality makes citizens more tolerant of inflation. This study uses the International Social Survey Program, the Integrated Values Surveys, and the Comparative Study of Electoral Systems, which together include 293,100 respondents from 53 countries between the years 1976 and 2016 to demonstrate that overall, inequality significantly moderates citizens' inflation aversion.     

Inequality and the business cycle: evidence from U.S. survey data

ABSTRACT

We study the effects of macroeconomic shocks on measures of economic inequality obtained from U.S. survey data. To identify aggregate supply, aggregate demand, and monetary policy shocks, we estimate vector autoregressions and impose sign and zero restrictions on impulse response functions. We find that the effects of the macroeconomic shocks on inequality depend on the type of shock as well as on the measure of inequality considered. Contractionary monetary policy shocks increase expenditure and consumption inequality, whereas income and earnings inequality are less affected. Adverse aggregate supply and demand shocks increase income and earnings inequality, but reduce expenditure and consumption inequality. Our results suggest that different channels dominate in the transmission of the shocks. The earnings heterogeneity channel is consistent with the inequality dynamics after monetary policy shocks, but it appears to be less crucial when the economy is hit by either aggregate supply or aggregate demand shocks. Using variance decompositions, we find that although the macroeconomic shocks account for large shares of the variation in the macroeconomic variables, their contributions to the dynamics of the inequality measures are limited.

How Monetary Policy Affects Your Gross Domestic Product

During the financial crisis, monetary policy was loosened significantly. Debate continues about the extent to which low interest rates and quantitative easing (QE) may have had adverse distributional impacts, whether by income, wealth, age or region. Using quantified simulations on micro data, I show that looser monetary policy had a significantly positive financial impact on the majority of cohorts of UK society. The impact of monetary policy loosening on income and wealth inequality was small and the overall impact on household welfare significantly positive. These results differ from public perceptions of monetary policy. Personalised information on the impact of monetary policy on household balance sheets could help to correct these misperceptions.     

From households to national statistics: Macroeconomic effects of Women's empowerment

How do shifts in intra-household gender dynamics affect the economy at large? This paper parametrizes intra-household gender-powered decision-making and endogenous distributions of income to allow for the aggregation of key macroeconomic variables. In equilibrium, we find that greater women's empowerment increases precautionary savings to offset low endowment realizations. The effect is stronger among poor households who hedge against hitting a subsistence bound. Given the boost in savings at the bottom of the distribution, more empowerment leads to less poverty and lower income inequality. Another equilibrium prediction of the model is an increase in the household's food intake regardless of income, reflecting women's greater preference for food compared to men. The model's predictions are mapped to Mexico's 2014 National Household Income and Expenditure Survey which identifies the gender of the head of the household. These predictions have policy implications in the areas of monetary policy, social policy, financial intermediation and banking.     

Policy,Demography, and Market Income Volatility: What Shaped Income Distribution and Inequality in Australia Between 2002 and 2016?

Isolating the impact of policy, demographic shifts, and market volatility on changes in income inequality is of great interest to policymakers. However, such estimation can be difficult due to the complex interactions and evolutions in the social and economic environment. Through an extended decomposition framework, this paper estimates the effect of four main components (policy, demography, market income and other factors) on the year-over-year changes in income inequality in Australia between 2002 and 2016. This was a period marked by substantial policy, population, and economic shifts due to factors such as the mining boom, the global financial crisis and increasing immigration. The framework also incorporates a flexible non-parametric market income model which captures demand-side shock better than a standard parametric model. Our results suggest that market income was the primary driver of income inequality for all segments of the income distribution in Australia over the past 15 years. Policy factors, moreover, have had the largest net impact on reducing inequality overall, especially for lower income earners.     

The Redistributive Effects of a Minimum Wage Increase in New Zealand: A Microsimulation Analysis

This paper examines the potential effects on inequality and poverty of a minimum wage increase, based on a microsimulation model that captures the details of household composition and the income tax and welfare benefit system and allows for labour supply responses. Results suggest that, largely due to the composition of household incomes, a policy of increasing the minimum wage has a relatively small effect on the inequality of income per adult equivalent person, and a money metric utility measure, using several inequality indices. Hence, the minimum wage policy does not appear to be particularly well targeted, largely due to many low wage earners being secondary earners in higher income households, while many low income households have no wage earners at all. These results are reinforced when allowing for wage spillovers further up the wage distribution. Nevertheless, a minimum wage increase can have a more substantial effect on some poverty measures for sole parents in employment.     

How Does Fiscal Consolidation Impact on Income Inequality?

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non‐linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income.     

The political economy of income comparisons and economic growth

The literature on income inequality has provided various explanations as to how income inequality can affect growth, with the emphasis on ideas such as investments in human capital, issues of occupational choice, or the redistributive policies of governments. Inequality not only has a direct effect on the distribution of consumption in an economy, but it also has a powerful effect on people's subjective sense of well being. This paper takes a novel approach by focusing on the way in which a government's choice of economic policy can be influenced by how individuals perceive themselves relative to other individuals, both within the country and in foreign countries. The chosen policy affects economic growth, with the assumption being that policies that promote growth also tend to result in more switching of individuals between income groups. We show that the government's optimal policy depends on the importance of both inside country and outside country income comparisons, the fraction of national income earned by the different income groups, the potential magnitude of economic growth, the probability of switching between income groups in the presence of growth, and the relative importance of the various income groups. The model predicts that a greater degree of inside country income comparison is bad for growth whereas more outside country comparison is good for growth.     

The impact of (un)conventional expansionary monetary policy on income inequality – lessons from Japan

ABSTRACT

This paper analyzes the impact of conventional and unconventional monetary policy on income inequality in Japan, using hitherto unexplored data from the Japan Household Panel Survey. Empirical evidence shows that expansionary monetary policy in Japan has contributed to diminishing the gender pay gap through an increase in working time of women relative to men, but also to increasing the education pay gap. These effects may have materialized via the aggregate demand channel and the labour productivity channel. In contrast, expansionary monetary policy has had no significant impact on the development of the age pay gap.     

Does unconventional monetary policy affect inequality? Evidence from Japan

Inequality has been largely ignored in the literature and practice of monetary policy, but is gaining more attention recently. Here, we exclusively focus on the impact of unconventional monetary policy (UMP) on inequality. We look at how the recent UMP in Japan affected inequality, using household survey data. Our vector auto regression (VAR) results show that UMP widened income inequality after 2008Q3 as the Bank of Japan (BoJ) resumed its zero-interest rate policy and reinstated UMP. This is largely due to the portfolio channel. To the best of our knowledge, this is the first study to empirically analyse the distributional impact of UMP. Japan’s extensive experience with UMP may hold important policy implications for other countries.     

The role of fiscal policy in the St. Louis model: Nonparametric estimates for a small open economy

This paper reevaluates the efficacy of monetary and fiscal policies and bidirectional causality between income and each of the policy instruments used in the St. Louis model for aggregate demand using nonparametric (or infinite parametric) spectral methods. We proceed by estimating the strength of the correlations (or partial coherences) between income and each of the policy instruments over various frequencies. Then we obtain the corresponding band regression and Hannan's efficient estimates of both the lead and lag coefficients in the St. Louis model. The analysis is carried out with seasonally adjusted quarterly data and is divided into the flexible, fixed, and managed flexible exchange rate regimes. We find that while estimates from parametric regressions yield the standard conclusions for the St. Louis model, results from the nonparametric analysis are quite different. Specifically, the results of our analysis reveal that (i) both monetary and fiscal instruments are strongly correlated with income over cycles of 10 quarters or longer for the most recent period of the managed flexible exchange rate regime, and (ii) bidirectional causality exists between income and the fiscal policy instrument. These results suggest that both monetary and fiscal policy have a long-lasting effect on aggregate demand and that bidirectional causality exists between income and policy instruments. An explanation for the existence of bidirectional causality might be that the Canadian government generally pursued a purposeful discretionary fiscal policy during the post-World War II period. Furthermore, it appears that discretionary policy action may have been anticipated by rational, farsighted, and forward-looking economic agents. Finally, our results for the flexible exchange rate and fixed rate regimes are in agreement with the Mundell-Fleming view of the role of monetary fiscal policy in an open economy.     

Infant mortality,relative income and public policy

Do health outcomes depend on relative income as well as on an individual's absolute level of income? We use infant mortality as a health status indicator and find a significant and positive link between infant mortality and income inequality using cross-national data for 93 countries. Holding constant the income of each of the three poorest quintiles of a country's population, we find that an increase in the income of the upper 20% of the income distribution is associated with higher, not the lower infant mortality. Our results are robust and not just caused by the concave relationship between income and health. The estimates imply a decrease in infant mortality by 1.5% for a one percentage point decrease in the income share of the richest quintile. The overall results are sensitive to public policy: public health care expenditure, educational outcomes, and access to basic sanitation and safe water can explain the inequality–health relationship. Thus, our findings support the hypothesis of public disinvestment in human capital in countries with high income inequality. However, we are not able to determine whether public policy is a confounder or mediator of the relationship between income distribution and health. Relative deprivation caused by the income distance between an individual and the individual's reference group is another possible explanation for a direct effect from income inequality to health.     

Income redistribution during a disinflation

This paper estimates the income redistribution among different sectors of society that results from a government disinflation policy. A model of wage setting in the U.S. economy is developed and then simulated for alternative money growth paths and private-sector behavioral parameters. It is found that a sudden change in monetary policy can cause significantly more income redistribution than a slow monetary deceleration. The paper concludes that a monetary policy rule which generates greater price stability may encourage a wage-setting rule in which wages are more responsive to monetary policy.     

The inequality channel of monetary transmission

We examine optimal monetary policy in the presence of inequality by introducing unskilled agents with no access to the financial system into a DSGE model with sticky prices. Our main results are: (i) a contractionary interest rate shock increases inequality, while inflation and the output gap fall; (ii) the welfare-based objective of monetary policy includes inequality stabilization; (iii) as the proportion of unskilled agents increases, welfare decreases; and (iv) under scarcity of skilled agents, monetary policy is weakened, while fiscal policy produces a more relevant impact on the economy.     

当前宏观经济政策中几个疑点问题分析

本在充分肯定当前宏观经济政策基本走向的同时,对财政政策、货币政策、收入分配政策中几个疑点问题进行了全面深入的分析,提出了富有新意的见解。作的结论是：“积极的财政政策”、“适当的货币政策”,这样的概括和称谓不科学;反通货紧缩用货币量的单纯扩张不能通缩的结果很可能是滞胀;公职人员加薪不能带动其他社会成员增收,其它社会群体增加收入要从他们所处的现实经济关系中去寻找。     

我国居民收入不平等的主要原因：市场还是政府政策？

市场因素和政府收入再分配政策是决定一国居民收入不平等程度的两个重要因素。本文采用中国家庭收入调查（China Household Income Project ,CHIP）住户数据,计算出我国居民市场收入基尼系数与可支配收入基尼系数,并同发达国家进行比较,借此探讨目前我国居民收入不平等是由市场力量造成的,还是政府收入再分配政策力度不足的结果。研究发现,从市场收入基尼系数来看,我国与发达国家之间的差距并不大。由此认为,政府收入再分配政策效果不明显是导致我国居民收入分配不平等状况较发达国家严重的主要原因。加大转移支付等再分配政策力度是缓解和改善目前我国居民收入不平等的主要途径。
