Key Terms to Review (45)
20:20 ratio: The 20:20 ratio is a concept used in economics to illustrate income distribution within a society, particularly focusing on the share of income received by the top 20% of earners compared to the bottom 20%. This ratio helps highlight the level of income inequality present in an economy, emphasizing disparities that may exist and prompting discussions around redistribution policies aimed at achieving a more equitable distribution of wealth.
Absolute Poverty: Absolute poverty refers to a condition where an individual or household lacks the financial resources to meet the basic necessities of life, such as food, clean water, shelter, and healthcare. This state of deprivation is often measured against a specific income threshold, typically defined by international standards, making it a stark contrast to relative poverty, which considers the income level compared to others in society.
Asset-building policies: Asset-building policies are strategies and programs designed to help individuals and families accumulate wealth and resources, enhancing their financial stability and promoting economic mobility. These policies aim to bridge the wealth gap, particularly among low- and middle-income households, by providing access to savings accounts, homeownership opportunities, education, and investment resources. The focus is on creating pathways for economic empowerment and reducing income inequality through the intentional accumulation of assets.
Atkinson Index: The Atkinson Index is a measure of income inequality that focuses on the distribution of income within a population and allows for the evaluation of social welfare. It considers not only the inequality in income but also incorporates a societal value judgment about the level of inequality that is acceptable, making it a useful tool for analyzing income distributions and assessing redistribution policies.
Conditional cash transfers: Conditional cash transfers (CCTs) are financial incentives provided to low-income individuals or families, contingent upon their compliance with specific behavioral requirements, such as ensuring children's school attendance or receiving regular health check-ups. These programs aim to alleviate poverty while promoting investments in human capital, ultimately addressing income inequality and fostering greater social equity.
Consumer behavior: Consumer behavior is the study of how individuals make decisions to spend their available resources (time, money, effort) on consumption-related items. It examines the factors that influence what, why, and how consumers buy products and services, highlighting the interplay between psychological, social, and economic influences on purchasing decisions.
Crime rates: Crime rates refer to the frequency of criminal offenses committed within a specific area over a given time period, typically expressed per 1,000 or 100,000 residents. These rates are important indicators of social issues and can be influenced by various factors such as economic conditions, law enforcement practices, and community programs. Understanding crime rates can help identify correlations with income inequality and the effectiveness of redistribution policies aimed at addressing these disparities.
Earned income tax credit: The earned income tax credit (EITC) is a refundable tax credit designed to support low to moderate-income working individuals and families, primarily aimed at reducing poverty and incentivizing work. By providing a financial benefit that increases with the taxpayer's income up to a certain threshold, the EITC not only helps to alleviate income inequality but also encourages employment among those who might otherwise be discouraged from working due to the burden of taxation.
Educational attainment: Educational attainment refers to the highest level of education an individual has completed, such as high school, college, or advanced degrees. This measure is crucial for understanding socioeconomic status, as it often correlates with income levels and employment opportunities, influencing broader economic patterns and social mobility.
Employment protection legislation: Employment protection legislation refers to laws and regulations designed to protect employees' rights in the workplace, ensuring job security, fair treatment, and safe working conditions. These laws can include provisions regarding wrongful termination, workplace safety, and minimum notice periods for layoffs. The aim is to balance the power dynamics between employers and employees, contributing to broader social objectives like reducing income inequality and promoting fair redistribution of resources.
Equity-efficiency trade-off: The equity-efficiency trade-off refers to the balancing act between achieving fair distribution of resources (equity) and maximizing overall economic output or productivity (efficiency). In discussions of income inequality and redistribution policies, this concept highlights the tension between providing support to disadvantaged groups while maintaining incentives for production and innovation.
Fiscal policies: Fiscal policies are government strategies regarding taxation and spending to influence a nation's economy. These policies aim to manage economic stability, stimulate growth, and address issues like income inequality through various measures such as public services and welfare programs.
Gini Coefficient: The Gini Coefficient is a statistical measure that represents income inequality within a population, ranging from 0 to 1. A coefficient of 0 indicates perfect equality, where everyone earns the same income, while a coefficient of 1 signifies maximum inequality, where one person has all the income and everyone else has none. This measure is crucial for understanding how income is distributed across different groups and can help inform policies aimed at addressing income disparities.
Globalization: Globalization is the process by which businesses, cultures, and economies develop international influence or operate on an international scale. It facilitates the interconnectedness of markets and the flow of goods, services, information, and people across borders, significantly impacting economic dynamics and societal structures around the world.
Healthcare access: Healthcare access refers to the ability of individuals to obtain necessary medical services and treatments when needed. It encompasses various factors, including availability, affordability, and accessibility of healthcare facilities and providers, which can significantly affect health outcomes. The disparities in healthcare access often mirror broader societal issues like income inequality and the effectiveness of redistribution policies aimed at addressing these inequities.

These programs can include financial assistance, education, and resources aimed at making homeownership more accessible and affordable, thereby addressing income inequality and promoting wealth-building opportunities for disadvantaged groups.
Income Deciles: Income deciles are statistical measures that divide a population into ten equal parts based on income levels, allowing for the analysis of income distribution within a society. Each decile represents 10% of the population, ranked from the lowest to the highest income earners, providing insights into income inequality and economic disparity. Understanding income deciles is essential for evaluating economic policies aimed at redistribution and assessing the effectiveness of initiatives designed to reduce poverty and enhance equity.
Income Quintiles: Income quintiles are statistical measures that divide a population into five equal parts based on income levels, with each quintile representing 20% of the population. This division helps to analyze income distribution and inequality, highlighting disparities in wealth and resources among different segments of society. Understanding income quintiles is essential for evaluating the effectiveness of redistribution policies aimed at addressing income inequality.
Income Share Ratios: Income share ratios are metrics that express the proportion of total income earned by different segments of the population, typically categorized by income levels or groups. These ratios help in assessing income distribution and identifying levels of income inequality, as they indicate how wealth is shared across various segments of society and can provide insights into economic disparities and the effectiveness of redistribution policies.
Individual Development Accounts: Individual Development Accounts (IDAs) are matched savings accounts designed to help low-income individuals save for specific purposes like education, homeownership, or starting a small business. These accounts encourage saving by offering matching funds from government or nonprofit sources, which can significantly increase the savings impact for individuals who may struggle to accumulate wealth due to economic constraints.
Inherited wealth: Inherited wealth refers to the assets and financial resources that individuals receive from their ancestors, typically through wills or trusts, rather than earning them through personal effort or labor. This form of wealth often contributes to the perpetuation of economic disparities, as those who inherit significant assets can accumulate further wealth, while those without such inheritances may struggle to achieve similar financial stability.
Intergenerational transfers: Intergenerational transfers refer to the flow of resources, wealth, or benefits from one generation to another, often in the form of financial support, inheritance, or shared assets. These transfers play a significant role in shaping income distribution and can influence economic inequality by providing some individuals with advantages over others based on family wealth or support.
Job displacement: Job displacement refers to the involuntary loss of employment, often due to external factors such as economic shifts, technological advancements, or organizational changes. This phenomenon can lead to significant economic and social challenges, especially when it affects a large segment of the workforce, contributing to widening income inequality and raising questions about appropriate redistribution policies.
Lorenz Curve: The Lorenz Curve is a graphical representation of income or wealth distribution within a population, illustrating the degree of inequality present. It plots the cumulative percentage of total income received by the bottom x% of the population, allowing for a visual comparison between perfect equality and actual distribution. The further the curve is from the line of equality, the greater the level of inequality, which is essential for understanding redistribution policies.
Marginal Tax Rates: Marginal tax rates refer to the percentage of tax applied to each additional dollar of income earned. This concept is crucial in understanding how taxation impacts individuals and businesses, particularly in the context of income inequality and redistribution policies, as higher marginal rates can discourage additional earnings while potentially providing more funds for social programs aimed at reducing inequality.
Market Distortions: Market distortions occur when market forces are altered or disrupted, leading to inefficiencies in the allocation of resources. These distortions can arise from various factors such as government interventions, externalities, monopolies, or information asymmetries. They often result in prices that do not reflect true supply and demand, creating inequalities and inefficiencies in markets.
Minimum wage laws: Minimum wage laws are regulations set by the government that establish the lowest hourly wage an employer can pay their employees. These laws aim to protect workers from unduly low pay and reduce income inequality by ensuring a baseline level of earnings for low-wage workers. They also impact labor market dynamics, as higher minimum wages can influence employment levels, pricing, and overall economic growth.
Palma Ratio: The Palma Ratio is a measure of income inequality that compares the share of income received by the top 10% of earners to the share received by the bottom 40%. It highlights disparities in income distribution and emphasizes the concentration of wealth among the highest earners relative to those in lower income brackets, making it a useful tool for assessing economic inequality and informing redistribution policies.
Percentile ratios: Percentile ratios are statistical measures that indicate the relative standing of a value within a dataset, often used to analyze income distribution and inequality. They help in understanding how individual incomes compare to the entire population by dividing it into 100 equal parts, providing insight into economic disparities and the effectiveness of redistribution policies. This understanding is crucial for evaluating income inequality and the impact of policy interventions aimed at promoting equity.
Progressive tax systems: A progressive tax system is a taxation structure where the tax rate increases as the taxable income increases, meaning higher earners pay a larger percentage of their income in taxes compared to lower earners. This system aims to reduce income inequality by redistributing wealth through taxation, allowing governments to fund social programs and services that benefit society as a whole.
Progressive taxation: Progressive taxation is a tax system in which the tax rate increases as an individual's income rises, meaning that higher earners pay a larger percentage of their income in taxes compared to lower earners. This approach aims to reduce income inequality by redistributing wealth and funding public services that benefit society as a whole. The underlying philosophy is based on the principle that those with greater financial capacity should contribute a fairer share to the funding of government programs and social welfare initiatives.
Public education policies: Public education policies are government regulations and initiatives aimed at organizing, funding, and improving the educational system for the general population. These policies play a crucial role in addressing issues like access to education, quality of instruction, and the equitable distribution of resources, which are essential for reducing income inequality and promoting social mobility.
Relative poverty: Relative poverty refers to the condition in which an individual or group lacks the minimum amount of income needed to maintain the average standard of living in the society in which they reside. It emphasizes inequality by comparing a person's economic status to that of others within their community, rather than just focusing on absolute measures of poverty, like survival needs. This concept is important for understanding how economic disparities affect social cohesion and the effectiveness of redistribution policies.
Skill-biased technological progress: Skill-biased technological progress refers to the phenomenon where technological advancements favor skilled workers over unskilled ones, leading to increased demand for skilled labor. This type of progress can exacerbate income inequality, as those with higher education and specialized skills benefit more from new technologies, while lower-skilled workers may face stagnation or job displacement. The result is a widening gap in earnings between skilled and unskilled laborers, influencing broader economic and social dynamics.
Social cohesion: Social cohesion refers to the bonds that bring individuals and groups together in a society, fostering a sense of belonging, shared values, and mutual trust. It plays a crucial role in promoting social stability, reducing conflict, and enhancing overall well-being within communities. High levels of social cohesion can help mitigate the negative effects of income inequality and inform effective redistribution policies.
Social welfare programs: Social welfare programs are government initiatives designed to provide financial support and assistance to individuals and families in need, aimed at improving their standard of living and reducing poverty. These programs play a crucial role in addressing income inequality by redistributing wealth and resources to marginalized groups, thus fostering economic security and social stability.
Technological Change: Technological change refers to the process through which new technologies are developed and implemented, leading to improvements in efficiency, productivity, and the way goods and services are produced and delivered. This change can impact various sectors of the economy, influencing income distribution and economic structures, as well as shaping policies aimed at redistributing wealth and resources to address inequalities that arise from such advancements.
Temporary Assistance for Needy Families: Temporary Assistance for Needy Families (TANF) is a federal assistance program in the United States that provides financial aid to low-income families with children. This program aims to help families achieve self-sufficiency through time-limited assistance, work requirements, and promoting personal responsibility. TANF is a key component of income redistribution policies, as it directly addresses poverty by providing temporary support to those in need while encouraging employment and personal development.
Theil Index: The Theil Index is a statistical measure of income inequality that quantifies how much the distribution of income deviates from a state of complete equality. It provides insights into the extent of inequality within a population, allowing policymakers to assess and compare the impact of redistribution policies. This index helps to understand the broader implications of income disparities on economic performance and social stability.
Unionization rates: Unionization rates refer to the percentage of workers in a specific sector or geographical area who are members of labor unions. This metric is important as it provides insight into the collective bargaining power of workers, influences wage levels, and can impact income distribution within an economy. Higher unionization rates typically correlate with stronger labor rights and increased wage equality, which plays a critical role in discussions about income inequality and redistribution policies.
Universal Basic Income: Universal Basic Income (UBI) is a proposed economic policy that provides all citizens with a regular, unconditional sum of money, regardless of their circumstances. This concept aims to reduce poverty and income inequality while promoting social and economic stability by ensuring a basic standard of living for everyone. By guaranteeing a consistent income, UBI seeks to address the challenges posed by automation and changing labor markets.
Universal healthcare systems: Universal healthcare systems are frameworks designed to provide all citizens with access to necessary medical services without financial hardship. These systems aim to eliminate barriers to healthcare, such as cost and accessibility, by often funding services through taxation or government provisions, thereby promoting health equity and improving overall population health.
Urbanization: Urbanization is the process by which an increasing percentage of a population comes to live in urban areas, leading to the growth and expansion of cities. This shift often results from rural-to-urban migration, economic opportunities, and changes in lifestyle, impacting social structures and economic dynamics significantly. Urbanization is closely linked to various socioeconomic factors, including income inequality and redistribution policies that can arise as cities grow and evolve.
Wage pressures: Wage pressures refer to the upward force on wages that arises from various economic factors, including labor market conditions, inflation, and the demand for skilled workers. These pressures can lead to wage increases that may affect income distribution and overall economic stability. In the context of income inequality and redistribution policies, wage pressures can highlight disparities in earnings across different sectors and occupations, raising questions about the fairness of compensation and the role of policy interventions.
Welfare payments: Welfare payments are financial assistance provided by the government to individuals or families in need, aimed at ensuring a basic standard of living and alleviating poverty. These payments are often a key part of redistribution policies that seek to reduce income inequality by transferring resources from wealthier individuals or groups to those who are less fortunate. Welfare payments can take various forms, including cash benefits, food stamps, housing assistance, and healthcare support.
