Distinguishing between the Effects of Inequality in Different Parts of the Income Distribution. Journal of Economic Growth 10 (3): 27396. Growth Theory through the Lens of Development Economics. Handbook of Economic Growth, Vol. Alesina and Perotti (1996) analyze this channel and find that an increase in inequality (inversely related to the income of the middle class, in their estimation) has a statistically negative effect on political stability. Rodrik, D. 1999. Relaxing each of these assumptions creates channels through which growth can have distributional effects, including for inequality and poverty. Inequality provides incentives to work, save, and investthose who do will receive higher returns than those who do not. Inequality raises the question of the relationship between rich and poor, exactly the question that the War on Poverty and the opportunity approach conceals. And how does growth affect inequality, if at all? Without enforcement, the best laws wont have much impact. Moreover, if segments of the population do not perceive that growth is benefiting them, it can fuel discontent in the society and if not addressed can lead to political instability and social unrest. Banerjee, A., and E. Duflo. They then discovered that a major reason for this was the feeling that people could not lean on their community for support when times were tough, and this left low-income people extremely isolated. Despite government guidance for micro-lenders to provide debt relief, these micro-loan providers are unethically coercing people into selling their land and housing, used as collateral, when they cant pay back their loans. As shown in Figure 6, it is an empirical regularity that as countries become richer, the government is capable of raising more fiscal revenue and increase the capacity of providing public goods. Acemoglu, D., and P. Restrepo. Empirical evidence shows that inequality of wealth, not just inequality of income, reduces the effectiveness of educational interventions (Deininger and Olinto 2000). The redistribution channel is illustrated by Alesina and Rodrik (1994) based on the endogenous growth model of Barro (1990), where government spending is productive but is financed through distortionary capital taxation. Grundlegung der politischen konomie, 3rd ed. It also means improving transparency and oversight to root out corruption and wasteful practices that take resources away from the people who need it most. Building on this work, using data from a panel of 80 countries, Kraay (2006) decomposes the changes in absolute poverty into three potential sources: the growth rate of average income; the sensitivity of poverty to growth; and a poverty-reducing pattern of growth (changes in relative income). Galor and Weil (1996) develop a theory whereby gender inequality, measured as the wage gap between male and female workers, has a long-term impact on growth. Channels by which Inequality and Poverty Can Depress Growth, Appendix A. On the other hand, capital account liberalization might increase the frequency of financial crises (Kaminsky and Reinhart 1999). Second, high initial poverty dulls the impact of growth in reducing poverty. De Loecker, J., and J. Eeckhout. Governments may also increase debt following financial market integration (Azzimonti, de Francisco, and Quadrini 2014), raising the likelihood of a debt crisis. It means that there is no way for me to get what I need without putting myself in danger. Das Kapital: Kritik der politischen Oekonomie, Do Rising Tides Lift All Prices? In the absence of developed financial and insurance markets, the poor will avoid investing in profitable investment opportunities that are intrinsically risky. How racial and regional inequality affect economic opportunity. Indeed, in recent years, the labor share of output across advanced and emerging market economies has fallen as a result of capital deepening and technological progress (Dao, Das, and Koczan 2019). Growth Diagnostics. Poverty trap is a common narrative of economic development whereby some countries are stuck in poverty and would need external support (or a big push) for them to escape it. Poverty across Country Groups, 1980s2010s. Inequality and Growth in Brazil, Maria Emma Santos, Carlos Dabs , and Fernando Delbianco, Growth and Poverty Revisited from a Multidimensional Perspective, Journal of Development Studies 55 (2) : 118, Re -Estimating the Relations hip between In equality and Growth, Inequality of Opportunity, Inequality of Income, and Economic Growth, The Role of In equality for Poverty Reduction, World Bank Policy Research Working Paper 9409, Income Inequality and Economic Growth: Heterogeneity and Nonlinearity. The poverty ratio is in terms of 2011 purchasing power parity (PPP). In short, the impact of growth on poverty and inequality depends on how growth is distributed across the rich and poor. Ostry, J. D., Berg, A., & Tsangarides, C. G. (2014). Milton Friedman (Friedman 1962; Friedman and Friedman 1980) based his opposition to redistributive policies aimed at reducing inequality of outcomes on the grounds of efficiency, arguing that they could distort incentives and induce an inefficient allocation of resources. Workers in the manufacturing sector experience an increase in income, while the ones staying in the traditional sector remain with low wages, resulting in higher income inequality. Final poverty ratio (2010s) at $3.20 a day: average index for the 2010s up to 2019. Wage Inequality: Revising the Revisionists. The Review of Economics and Statistics 90 (2): 30023. Unequal power is found to lead to the formation of institutions that perpetuate inequalities in power, status, and wealth, which typically are also bad for the investment, innovation, and risk-taking that underpin long-term growth (World Bank, 2006). The impact of poverty and inequality on growth is likewise ambiguous, as several channels mediate the relationship. WebItsImpacts and otivation Thereisawelldocumentedupwardtrendininequalityinhighandmiddleincome If poverty and inequality are considered social ills, people may be willing to purchase reductions in poverty and inequality through redistribution policies as overall incomes rise (that is, poverty and inequality reduction function as normal goods, in which demand increases with income). This stylized fact is better known as the Wagners Law (Wagner 1893) and captures a channel through which growth leads to an increase in the size of the government, which can reduce poverty and improve the income distribution provided spending is efficient and its composition benefits the poor. 2018. An increase in growth is a necessary condition for lifting incomes; improving nutrition; and expanding access to health, education, and opportunities for high-quality jobs. Do these terms all mean the same thing? Key Channels in the GrowthPovertyInequality Nexus, Empirical Literature on the Growth-Poverty-Inequality Nexus. Over 70 percent of the worlds population live in countries that recently experienced growing inequality. Cerra et al. Many of these studies find that inequality, typically measured by a Gini coefficient, enters with a negative and statistically significant sign in cross-country growth regressions, indicating that an increase in inequality leads to lower economic growth. poverty A. Empirical Estimates of the Impact of Poverty and Inequality on Growth, B. Income generated by the sectors can spill over into demand for other goods and spur industrialization, but only if income is distributed broadly enough (Murphy, Shleifer, and Vishny 1989). On the other hand, the impact of growth on inequality (a relative measure of the well-being of the poor) is ambiguous and depends on the sources of growth. In particular, growth is an inverted U-shaped function of changes in inequality such that a change in the Gini coefficient in either direction is correlated with lower future growth. If Im poor, it exacerbates my need to rely on community, but what does it mean if I dont trust my community? In other words, equality of opportunity does not pose a trade-off with economic growth. Growth increases aggregate resources, including the tax base and the public sectors capacity to collect taxes. But most plausible mechanisms suggest that poverty and inequality reduce growth, at least in the long run. Growth Is Good for the Poor. Journal of Economic Growth 7 (3): 195225. Inequality @RepRaskin Gini disposable indicates the Gini coefficient after taxes and transfers. The Two Poverties. Working Paper 0116, Department of Economics, Massachusetts Institute of Technology. 2014. How Wealth Inequality and Poverty Connect Various studies examine different dimensions of the relationship. Central Bank of Chile. Innovation and Top Income Inequality. Review of Economic Studies 86 (1): 145. Implicitly, this analytical framework is centered on aggregate growth, rather than on distributional issues. Booth, C. 1891. Nearby Lake Turkana is too saline for human consumption. Donate to Giving Compass to help us guide donors toward practices that advance equity. [/pullquote] Ultimately, from the prices paid by the purchasers of the goods and services they are financing. Robust Determinants of Income Inequality. Oxford Review of Economic Policy 35 (3): 490517. More recently, Graetz and Michaels (2018) study the impact of the adoption of robots across industries in 17 OECD countries from 1993 to 2007. Through several experiments, they illustrate how the poor devote a significant fraction of their attention span to satisfying basic needs, such as obtaining food, leaving them with less attention to handle other problems, such as investment decisions that would enable their businesses to expand and grow. Governments also fail to invest in resources and programs that ensure all people have access to what they need. A case can be made that inequality can serve as an incentive for effort and investment.

Columbia University, New York. Barro (2000) estimates the impact of inequality on growth by splitting a sample of 100 countries into high and low-income samples. Instead, a permanent redistribution of wealth can achieve the optimal allocation. Second, social unrest might lead to a disruption of productive activities and therefore a reduction in productivity. Since the late 1980s, skill-biased technological change has led to job market polarization due to an increased demand for skilled and unskilled workers at expense of middle-class jobs, as new technologies are capable of performing routine tasks traditionally done by middle-wage workers (Goldin and Katz 2007). But governments do the opposite when they fail to rein in powerful people or companies from actions that result in people living in destitution. Blotevogel, R., E. Imamoglu, K. Moriyama, and B. Sarr. How are Inequality and Poverty Linked? - Fabrizio et al. Financial and debt crises often lead to severe recessions that disproportionately affect the poor and raise inequality (Cerra et al. However, the growth diagnostics analysis relies on a representative agent approach, which, like the Solow model, does not illuminate the distributional impacts of growth policies. Inequality And Growth: What Can The Data Say?, Growth Theory through the Lens of Development Economics, The Shape of Temptation: Implications for the Economic Lives of the Poor, Occupational Choice and the Process of Development, Government Spending in a Simple Model of Endogenous Growth, Inequality and Growth in a Panel of Countries. Market-based income inequality has risen steadily in advanced economies and some large emerging market economies. Benjamin, D., L. Brandt, and J. Giles. Whats going to happen to vulnerable families now? In a capitalist system, the distribution of income is consistent with the ethical principle, To each according to what he and the instruments he owns produce. This implies that in a free market economy, people should be rewarded according to their marginal productivity, resulting in some inequality of outcomes. Studies in Nonlinear Dynamics and Econometrics 24 (3). What Remains of Cross-Country Convergence? GDP omits some components of economic production, such as housework and home production, because it measures goods and services traded in market transactions. While GDP per capita growth in advanced economies has been slowing down every decade since the 1980s, growth has accelerated in emerging markets and low-income countries, particularly since the 2000s (Duttagupta and Narita 2017).6 Figure 4 shows recent trends in GDP per capita growth across different groups of countries. Emerging and developing economies: Entering a rough patch or protracted low gear? Journal of Policy Modeling 39 (4): 680698. But the composition and incidence of taxes and transfers is important. Consistent with Bnabou (1996), on average countries that exhibited lower levels of initial inequality also experienced higher rates of economic growth. Rodrik (1999) studies the interaction between social conflict (measured by inequality or ethnic and linguistic fragmentation) and the quality of government institutions in developing countries in response to external shocks (specifically, terms of trade shocks). Graetz, G., and G. Michaels. Average Growth in GDP per capita across Country Groups, 1980s2010s. Ivanic and Martin (2018) find that in poor countries, productivity gains in agriculture are generallyalthough not alwaysmore effective in reducing global poverty than the productivity gains in industry or services of equivalent size. 2005. Bnabou, R. 1996. Lakner, C., D. Gerszon Mahler, M. Negre, and E. Beer Prydz. Litschig, S., and M. Lombardi. Unemployment creates income losses in the short term, especially for those in lower-income groups such as people with lower educational attainment, ethnic minorities, and women (Hoynes, Miller, and Schaller 2012). An alternative behavioral channel through which poverty is perpetuated and economic growth prospects is curtailed is through the lack of self-control in consumption and saving decisions. Racial inequality is the unequal distribution of resources, power, and economic opportunity across race in a society. Matlack, J. L., and J. L. Vigdor. Aghion, P., U. Akcigit, A. Bergeaud, R. Blundell, and D. Hemous. Consequently, the reduction in the fertility rate leads to lower population growth and an increase in the stock of capital per capita, which in turns generates a positive feedback loop boosting growth and the relative wage of female workers. Governments should also aim to provide universal social protections, such as a welfare system, and should help people achieve greater economic security. 2018. In the Wealth of Nations, Adam Smith (1776) noted that wealth inequality could lead to social unrest and that the government had a role in protecting property rights and preventing the poor from seizing the property of the rich. Related evidence comes from the observation that despite the global reduction in poverty rates, cross-country evidence indicates a lack of convergence in poverty rates. For example, providing affordable internet access to low-income families could buffer them from future poverty, as does offering quality public education along with other continuing education courses designed to improve access to better jobs. Johnson, P. and C. Papageorgiou. Therefore, policy analysis must determine the distributional consequences as well as the growth consequences of policy interventions. For a cost-minimizing firm, the labor share is inversely related to the markup. This means eliminating corruption and self-dealing by politicians that can lead to misdirected or wasteful spending. Fertility and the Economy. Journal of Population Economics 5 (3): 185201. 2017. Our work shows that hardship increases for low-income individuals by reducing their ability to rely on their community as a buffer against financial and other related difficulties.. Channels from Poverty and Inequality to Growth, 1. Poverty and economic inequality are pressing human rights problems in the United States. Trade, Growth, and Poverty. The Economic Journal 114 (493): 2249. Macro-structural Policies and Income Inequality in Low-income Developing Countries. IMF Staff Discussion Notes No. Market Gini is before taxes and transfers. This requires that the benefits of growth are widely shared across society. Distinguishing between the Effects of Inequality in Different Parts of the Income Distribution, Journal of Economic Growth 10 (3): 27396, Reliving the 1950s: The Big Push, Poverty Traps, and Takeoffs in Economic Development, When Is Growth Pro-Poor ? In a sample of 156 countries covering 1960 to 2010, Marrero and Servn (2018) find that for low levels of poverty (below the median), poverty has an insignificant impact on growth (Figure 8). In contrast to poverty, there is no significant systematic relationship between a countrys income level and its market inequality (Figure 5, top right panel). Loayza, N. V., and C. Raddatz. A critical first step is developing a solid legal framework that protects peoples basic economic rights, like the right to an adequate standard of living, and provides for effective remedies for those whose economic rights are violated. Hoynes, H., D. L. Miller, and J. Schaller 2012. And governments need to monitor and enforce those laws. These results are robust to alternative samples and model specifications.

Globalization and technological change influence growth and inequality through different components of GDP. Does it really matter whether we sayinequality,poverty, or something else? Similarly, financial strife can encourage harmful behaviors, such as taking out payday loans, which can exacerbate the problem. 2007. Please give now to support our work, Why Poverty and Inequality are Human Rights Issues, Girls from the Kalokol Girls Primary School fetch water from a dry riverbed to carry back to their school, which does not have access to running water. Under this channel, inequality leads to a polarization of the society, social unrest, and violence, if the demands of the voters cannot be met through the traditional political system. Evidence for the United States (Dynan, Skinner, and Zeldes 2004), for instance, supports the notion that both saving rates and the marginal propensity to save are positively correlated with the level of income, suggesting that higher income inequality can lead to a higher savings rate, consistent with Kaldors hypothesis. The bottomline? Research by the World Bank indicates that when markets are imperfect (in credit, insurance, land and human capital), inequalities in power and wealth turn into unequal opportunities, leading to wasted productive potential and to an inefficient allocation of resources (World Bank, 2006; World Bank, 2013). Estimates are sensitive to assumptions on factors such as capital gains and untaxed income (Cerra et al. Through various mechanisms, growth increases education, health, and job opportunities for the poor and improves their access to public goods and services, lifting their incomes and prospects for the future.

For instance, Charles Booth (1891) , in Life and Labour of the People in London, published maps describing wealth and poverty levels street by street in the city of London. Inequalities between classes (large-scale groupings of people identified according to economic criteria) have widened both within and between countries (Greig et al., 2006). It can be defined narrowly or more broadly, depending on how well-being is understood. (2020) also analyze the consequences of firm size on the labor market share by developing a framework for superstar firms characterized by a winner takes most feature. What about the reverse relationship: that is, how do poverty and inequality affect growth? In their analysis of the impact of poverty on growth, Lpez and Servn (2015) develop an endogenous growth model with learning-by-doing externalities and subsistence consumption.
