1. Income inequality has increased in many developed countries over the past few decades, with the top income earners capturing a larger share of national income.
2. Factors contributing to rising income inequality include technological change, globalization, decline in unionization, and changes in tax and transfer policies.
3. The Gini coefficient is a widely used measure of income inequality, with a higher value indicating more unequal distribution.
4. Policies such as progressive taxation, minimum wage, and social safety nets can help reduce income inequality.
5. Income inequality can have social and economic consequences, including reduced social mobility, political instability, and slower economic growth.

Review Questions

• Explain how the Gini coefficient is used to measure income inequality and describe its implications.
  • The Gini coefficient is a statistical measure that ranges from 0 to 1, where 0 represents perfect equality (everyone has the same income) and 1 represents perfect inequality (one person has all the income). A higher Gini coefficient indicates a more unequal distribution of income within a country. The Gini coefficient provides insight into the degree of income inequality and can be used to compare the income distribution across different countries or over time. A high Gini coefficient suggests that a significant portion of the population has relatively low incomes, which can have social and economic consequences, such as reduced social mobility and slower economic growth.
• Describe the key factors that have contributed to the rise in income inequality in many developed countries in recent decades.
  • Several factors have contributed to the increase in income inequality in developed countries over the past few decades. Technological change, particularly the automation of routine tasks, has disproportionately benefited high-skilled workers and reduced the demand for middle-skill jobs. Globalization and the integration of the world economy have also played a role, as competition from low-wage countries has put downward pressure on wages for some workers in developed countries. Additionally, the decline in unionization and changes in tax and transfer policies, such as reductions in top marginal tax rates and the weakening of social safety nets, have contributed to the widening of the income distribution.
• Evaluate the potential social and economic consequences of high levels of income inequality and discuss policy approaches that could be used to address this issue.
  • High levels of income inequality can have significant social and economic consequences. Socially, it can reduce social mobility and cohesion, as individuals from lower-income backgrounds face barriers to accessing education and economic opportunities. This can lead to political instability and social unrest. Economically, income inequality has been associated with slower economic growth, as it can limit the ability of lower-income individuals to invest in their human capital and participate fully in the economy. Policy approaches to address income inequality include progressive taxation, minimum wage increases, investments in education and training, and strengthening social safety nets. These policies can help redistribute income, provide opportunities for upward mobility, and promote more inclusive economic growth. Ultimately, addressing income inequality requires a multifaceted approach that considers both the causes and the consequences of this complex issue.
