Here is a summary of the key points from the passage:

  • There are different ways to define and measure income and inequality. The choice of definition and measurement impacts the conclusions drawn.

  • Income can be defined broadly to include non-monetary sources like imputed rent. Inclusion of public services would show less inequality between households.

  • Capital gains/losses and asset values also affect well-being but are imperfectly captured in income metrics. Realized capital gains significantly impact measured inequality.

  • Consumption may be a better indicator than income as it reflects ultimate spending ability. But consumption surveys have limitations and show mixed trends compared to rising income inequality in countries like the US.

  • Individual versus household units of analysis, adjusted versus unadjusted income definitions, inclusion/exclusion of taxes and transfers all lead to differing inequality measures from the same data.

  • Proper definition and consistent measurement over time are important to understand trends and draw conclusions about drivers of changing inequality within and across societies.

    Here is a summary of the key points:

  • Historically, household surveys have been the primary source of data on income inequality, though they have limitations like incomplete coverage and non-response bias.

  • Other sources like tax data and wealth records provide supplementary information but also have flaws in definitions and coverage over time.

  • Comparability across surveys is important but not always possible due to different methodologies and contextual factors in different countries.

  • Non-response rates in surveys have increased in recent decades, posing challenges in representing the full population, especially high-income groups.

  • The 1914-1945 period saw notable declines in inequality across many countries due to the income compression effects of World War I and II.

  • The post-WWII decades were characterized by falling inequality in both the US and Europe driven by rising wages, redistribution policies like taxes/transfers, and growth in welfare states.

  • However, starting in the 1980s, rising inequality trends re-emerged as welfare states struggled to keep pace and policy shifts reduced redistribution's equalizing impact.

So in summary, measuring inequality comprehensively over time relies on imperfect data sources that require adjustments, but key periods of change can still be identified.

Here are the key points:

  • Technological progress and globalization have increased demand for skilled labor while replacing some unskilled jobs, contributing to rising inequality in many countries. However, their impacts depend on context and can be shaped by policies.

  • Unions and collective bargaining helped compress wage differentials postwar, but their decline since the 1980s removed an equalizing influence in some places.

  • Postwar social policies and institutions supported equitable growth, but market deregulation and privatization attenuated redistribution.

  • Inequality results from interactions of economic forces with social norms, politics and policies. While technology and trade influence inequality, their impacts depend on responses and can be shaped by policies regarding education, infrastructure, social protection, tax systems, corporate governance etc.

  • Future trends will depend on choices around innovation direction, labor market policies, property rights, and frameworks guiding relation between labor, capital and the state. Recognizing these complex interactions is important for analyzing inequality and policy responses.

    Here is a summary of the key points:

  • Technological innovation and automation are changing the nature of work and impacting employment levels and the kinds of jobs available. This presents challenges for traditional goals like full employment.

  • Non-standard work arrangements like part-time, contract, freelance jobs are on the rise. Simple employment/unemployment metrics don't capture this complex job market reality.

  • Retirement as a discrete end-of-work phase is also changing as people stay active longer. Old models of a standard full-time career may be outdated.

  • Employment policy goals need to shift from just maximizing total employment to minimizing involuntary unemployment. An explicit target of 2% unemployment could focus efforts.

  • To support this, the author proposes a government job guarantee program that acts as an "employer of last resort" providing minimum-wage public/non-profit jobs for those seeking work. Several countries have precedents for such programs.

  • Updated targets, metrics and policy tools are needed to deliver full employment goals in today's varied and changing work environments. Technology and non-standard jobs must be properly accounted for.

    Here is a summary of the key points:

  • The passage proposes establishing a sovereign wealth fund in the UK modeled on Norway's successful fund. The UK fund would build up public wealth by investing in companies and property over the long term.

  • This contrasts with the UK's practice in recent years of selling off state assets rather than holding them to increase national net worth over time.

  • The fund would aim to build intergenerational equity by passing on more state assets to benefit future generations, similar to how Norway has used oil revenues.

  • It would not involve nationalizing companies, as the state could hold minority stakes and receive income without control. Investments would factor in social and environmental responsibilities.

  • Examples of France and UK establishing similar but smaller funds for specific purposes are given. Proposal estimates UK state net worth could be much higher if it had invested revenues since the late 1960s as Norway has done.

  • In summary, the passage advocates for a permanent sovereign wealth fund to increase UK public assets and net worth for current and future citizens through long-term equity investments.

    Here is a summary:

  • The proposal advocates creating a sovereign wealth fund to build up and pass on the state's long-term net worth, rather than selling off existing assets. This would allow future generations to benefit from wealth generated today.

  • A sovereign wealth fund would invest revenue from natural resources, land, property and other assets to grow the country's overall balance sheet over time.

  • Rather than cashing in these assets now, a sovereign wealth fund takes a long-term perspective by preserving and increasing the value of public assets for continuous benefit.

  • Revenue generated by the investments could still be used to fund important public services and initiatives while protecting against fluctuations in commodity prices or other economic shocks.

  • Establishing such a fund reflects an investment rather than consumption-based approach to public finances and intergenerational equity. It prioritizes maintaining and expanding a baseline of societal wealth and opportunities over the long run.

    Here are the key points regarding the argument about minimum wages and efficiency wages:

  • Efficiency wages refer to paying workers above the market clearing wage to incentivize higher productivity (e.g. through reduced shirking). This can benefit employers through increased output.

  • If employers find it beneficial to pay efficiency wages already without a minimum wage mandate, then the minimum wage would force them to pay more than their profit-maximizing level.

  • However, with a minimum wage set above existing wages, employers may be able to reduce monitoring and turnover costs since workers have more incentive to keep their jobs. This can partially offset the higher wage costs for employers.

  • There can be multiple equilibrium wage levels depending on social norms around work effort. A minimum wage could shift the equilibrium from a "low-wage, low-effort" outcome to a "high-wage, high-effort" outcome where norms incentivize greater productivity.

  • So while a minimum wage initially increases costs, it's theorized it could also boost productivity enough through these efficiency wage effects that both wages and employment rise overall, increasing economic efficiency rather than decreasing it.

The key idea is that minimum wages don't necessarily reduce efficiency according to this theory, as higher pay can incentivize workers in a way that offsets costs for employers through increased output.

Here is a summary:

  • Tax-benefit modeling is a useful tool for estimating the costs and impacts of policy proposals, but it has limitations in accounting for behavioral responses.

  • Official costings typically assume no behavioral changes, but this leads to uncertainty, as taxes and incentives influence behavior.

  • To better understand distributional effects, models need to consider how underlying determinants may change as people adapt to the new policies.

  • A footballer example showed this issue - a simple model assumes his pay stays the same, but realistically clubs may pass added tax costs to fans by paying players less net.

  • The paper analyzes 15 UK proposals and finds, for some, not incorporating behavioral responses leads to overestimating benefits and underestimating costs.

  • Overall, while tax-benefit modeling is valuable, policymakers must recognize its limitations and uncertainties that arise from simplifying assumptions about complex economic behaviors. Fully dynamic models are difficult but important for accurate policy evaluation.

    Here is a summary of the key points:

  • The proposals aim to meaningfully reduce inequality, poverty, and child poverty in the UK through reforms to the tax and social security systems.

  • They involve raising taxes on higher incomes and introducing a universal basic income called a "participation income." Revenues would fund reducing reliance on means-tested benefits.

  • Distributional analysis suggests the proposals would benefit lower incomes the most while higher incomes may lose out. This would significantly reduce income inequality.

  • Poverty rates and poverty gaps would be substantially decreased, more than halving the average shortfall from the poverty line. Child poverty would also decline sharply.

  • Introducing a participation income alongside other measures appears better able to meet targets for inequality and poverty reduction compared to just reforming social insurance.

  • While the calculations do not fully account for behavioral impacts, the analysis indicates the fiscal approach could lift many out of poverty and lower the costs of the benefits system.

  • More may still need to be done to directly address pre-tax income inequality through policies around employment, ownership, and long-term economic and social issues.

So in summary, the proposals aim to tackle inequality, poverty, and their depth through reforms centered on a universal basic income and higher taxes on top incomes.

Here is a summary of the key points from the passage:

  • The passage discusses economic inequality and the debate around the Transatlantic Trade and Investment Partnership (TTIP) agreement between the US and EU.

  • TTIP proponents argue it will boost economic growth and jobs, while critics argue it will mainly benefit large corporations and undermine efforts for high labor and environmental standards.

  • There are tensions between liberalized trade/investment policies and democratic policymaking authority/reducing inequality.

  • It is important TTIP does not limit governments' abilities to enact public interest regulations or empower corporations to privately enforce newly established investor rights outside domestic courts.

  • The TTIP debate illustrates the tensions between free trade goals and concerns about rising inequality, corporate influence on regulations, and maintaining democratic control over policymaking.

  • The context of increasing global economic concentration and inequality is an important backdrop for the TTIP negotiations.

In summary, the passage discusses the tensions in the debate around TTIP between trade liberalization and concerns about its potential effects on inequality, corporate influence, and regulatory autonomy.

Here are the key points summarized:

  • The document analyzes causes and effects of economic inequality and proposes actions to reduce it.

  • Part 1 provides historical and economic context on inequality trends and drivers like technology, globalization, and employment changes.

  • Part 2 presents proposals like strengthening workers' power, adjusting pay and employment policies, redistributing capital to workers, and reforming taxation and social security.

  • Part 3 addresses objections to reform concerning economic growth or globalization constraints, arguing they can be overcome.

  • The perspective is rising inequality can be curbed through well-designed policies without harming growth. Coordinated economic and social reforms are needed across areas like technology, employment, capital ownership, taxation and welfare.

  • Key proposals focus on spreading economic growth benefits more broadly through policies in these domains.
