Good Economics for Hard Times: Better Answers to Our Biggest Problems

A woman diagnosed with only six months to live is advised by her doctor to marry an economist and move to South Dakota. When she asks if it will cure her illness, the doctor replies, "No, but the half-year will seem pretty long." This joke underscores a deeper issue: the growing polarization in our world. From the US to India, political discourse has become a shouting match, and respect for differing views is dwindling.

In the US, split-ticket voting is at a record low, with 81% of party affiliates holding negative views of the opposition. Similar trends are evident in France and India, where the rise of the political right is causing alarm among the liberal elite. The "tribalization" of opinions extends beyond politics to views on social issues, fueled by personal values rather than facts.

The slowdown in global growth, trade wars, and widening inequality are critical economic challenges. Yet, conversations on these topics are often superficial, avoiding the complex realities. Economists study these issues deeply, but their insights are often ignored. The Brexit vote is a prime example where economists' warnings were disregarded.

Trust in economists is low—only 25% of people in the US and the UK trust them about their own field, a stark contrast to the 84% trust in nurses. This trust deficit stems partly from media portrayal and the failure of economists to communicate effectively. Academic economists are often drowned out by TV "economists" who are more about market optimism than evidence-based insights.

Economists, unlike physicists, work more like plumbers, using intuition, experience, and trial and error to solve problems. They often get things wrong but strive to refine their understanding based on new data. Good economics involves testing hypotheses, refining approaches, and being open to change.

This book aims to bridge the gap between economists and the public, sharing the best insights from economic research on pressing issues like inequality, trade, and technology. It emphasizes the importance of dignity and human contact in economic discussions, urging a shift from material obsession to a more holistic view of well-being.

Ultimately, the goal is not to convince you to agree with everything but to engage in meaningful dialogue, understand different perspectives, and work towards a better understanding of our economic priorities and societal care.

Can Economists and Politicians Bridge the Growing Political Divide?

Migration has become a central political issue across the globe, with misconceptions about migrant numbers and impacts fueling heated debates. Despite fears of overwhelming immigrant influxes, the percentage of international migrants has remained steady at around 3% of the global population since 1960. 

In Europe, non-EU migrants constitute less than 0.5% of the population annually. Yet, political rhetoric often exaggerates these figures, stoking fears of cultural erosion and economic threats.

Surveys reveal massive misperceptions about immigrants, with people overestimating their numbers and assuming they're less educated and more dependent on welfare. For example, Italians perceive their immigrant population to be 26%, while it's actually 10%. These fears are politically exploited, as seen in France with Marine Le Pen's exaggerated claims about immigrants.

Economically, the fear that migrants drive down wages is unfounded. Studies, including the famous Mariel boatlift analysis, show little to no negative impact on native wages from large immigrant influxes. In fact, immigrants often complement local labor, taking jobs natives are reluctant to do and stimulating local economies.

However, the decision to migrate is complex. Many potential migrants choose to stay despite economic incentives, due to connections, comfort, and a fear of the unknown. Research in Bangladesh showed that providing just a small financial incentive could significantly increase migration, highlighting how even minor barriers can deter movement.

The hesitance to migrate isn't just a developing world phenomenon. In the U.S., internal migration has declined, with low-skilled workers moving away from booming cities due to high living costs. This has created economic and social divides, with some regions left behind as others prosper.

To address these issues, policies should focus on easing migration processes and integration, offering support like housing and employment assistance. This would encourage more balanced migration, benefiting both migrants and host communities. Despite political challenges, understanding and addressing the real dynamics of migration can lead to more informed and effective policies.

Debunking Migration Myths: The Reality Behind Immigration Politics

In early March 2018, President Trump signed new tariffs on steel and aluminum, sparking a heated debate among economists and the public. A panel of senior economics professors unanimously disagreed with the idea that these tariffs would benefit American welfare. In contrast, public opinion was more divided, with many Americans supporting higher tariffs to encourage domestic production. 

The theory of free trade, rooted in David Ricardo's concept of comparative advantage, suggests that countries benefit from specializing in what they do best and trading for other goods. However, this theory doesn't account for the real-world complexities and the unequal distribution of trade benefits and losses. For example, in a survey, many Americans believed that low-skilled workers were hurt by trade with China, reflecting the public's awareness of trade's negative impacts.

Economist Paul Samuelson expanded on Ricardo's ideas, showing that while free trade increases overall income, it doesn't benefit everyone equally. Samuelson's work highlighted that in capital-rich countries like the U.S., trade could hurt workers' wages, while in labor-rich countries, wages could rise. This theory is supported by the Stolper-Samuelson theorem, which suggests that trade increases inequality in rich countries but reduces it in poorer ones.

However, real-world evidence often contradicts this theory. Countries like China and India, which experienced significant growth after opening up to trade, also saw rising inequality. This discrepancy suggests that the benefits of trade are not evenly distributed and that the process of adjusting to trade can be painful and slow.

In India, for example, trade liberalization in 1991 led to varying impacts across different regions. Some districts that were more exposed to trade experienced slower poverty reduction and higher child labor rates. This uneven impact reflects the "stickiness" of economies, where resources and labor do not easily move to more productive uses.

The challenges of benefiting from trade are further complicated by the importance of reputation and quality in international markets. For small producers in developing countries, building a reputation for quality can be an uphill battle, as seen in the case of Egyptian carpet weavers who struggled to secure export orders despite external support.

In the U.S., the "China shock" had a significant impact on manufacturing jobs, leading to concentrated economic distress in certain regions. The lack of reallocation of labor to new jobs and the resulting decline in wages and employment highlight the difficulties of adjusting to trade shocks.

To address these challenges, economists suggest policies that help workers retrain and move to new jobs. Programs like the Trade Adjustment Assistance (TAA) can be effective but are often underfunded. Expanding such programs and providing targeted support to affected workers and regions could help mitigate the negative impacts of trade.

In short, while free trade has potential benefits, it also creates significant challenges, particularly for workers in rich countries. Addressing these challenges requires targeted policies to help workers adapt and ensuring that the gains from trade are more evenly distributed.

Did Trump's Steel and Aluminum Tariffs Really Benefit American Workers?

In recent years, populist leaders across the globe have increasingly incited racial, religious, and gender-based animus, shaping elections and policies. For instance, in the 2016 U.S. elections, racial identity was a stronger predictor of support for Donald Trump than economic anxiety. This has legitimized public expressions of previously unspoken bigotry, exemplified by everyday incidents like a white woman calling the police on a black woman in a supermarket over unfounded suspicions.

Economists traditionally distinguish between preferences (like cake or cookies) and beliefs, with the former seen as beyond dispute. However, understanding the roots of these preferences is crucial for addressing policy issues like economic inequality and environmental protection. Economists Gary Becker and George Stigler argued that preferences are intrinsic and stable, uninfluenced by social pressures. Yet, real-world examples, like a Moroccan man prioritizing a television over food due to boredom, challenge this view.

Recent studies show poor people often make rational choices despite appearances. For example, cash transfers to the poor are largely spent on food, contradicting the presumption they would squander the money. Preferences, it turns out, can be shaped by context. For instance, people might conform to social norms or herd behavior, like forming lines at train platforms based on incorrect assumptions.

Game theory's "folk theorem" explains how social norms can be self-enforcing through community punishment. Elinor Ostrom's work demonstrated this in small communities managing shared resources. However, these norms can also sustain harmful practices like racial discrimination or caste systems, as shown by studies on caste-based violence in India.

The tension between individual rights and community norms is universal. In India, Gandhi's vision of self-reliant villages clashed with Dr. B.R. Ambedkar's advocacy for state protection of individual rights. Despite legal progress, caste discrimination persists at local levels.

In the U.S., President Obama's election was a milestone, but racial disparities remain significant. Economic and social mobility for African Americans lags behind, and hate crimes have risen. Trump's election and anti-immigrant rhetoric have further polarized society. Studies show that anti-immigrant sentiments are stronger in states with fewer immigrants, emphasizing identity over economic anxiety.

Contact with diverse groups can reduce prejudice, as shown by experiments and policies promoting integration in schools and workplaces. For example, randomized roommate assignments in universities fostered cross-group friendships and changed attitudes.

However, affirmative action and diversity policies remain contentious. The debate around Harvard's admission practices highlights the complexity of balancing merit and diversity. Contact-based interventions, like integrated schools and housing, can promote tolerance, but competition and unequal status can undermine these efforts.

In short, addressing prejudice requires understanding its roots in social context and economic conditions. Policies fostering integration and respect for individual dignity, alongside credible public conversations about policy, are crucial for a more inclusive society.

The Role of Identity in Shaping Global Policies and Prejudices

In the 1970s, the world experienced a dramatic shift when the oil embargo by OPEC sent shockwaves through the global economy, marking the beginning of a period of slow growth and "stagflation" in the West. This change was unexpected for many, as the preceding decades had seen unprecedented economic growth, particularly in the Western world. Known as "The Glorious Thirty," these years witnessed a significant rise in GDP and overall quality of life, driven by advancements in labor productivity, education, and technology.

However, since the 1970s, growth has been sluggish, sparking debates among economists about whether high growth rates will ever return. Robert Gordon argues that the era of rapid growth is over, while Joel Mokyr remains optimistic about future innovations driving growth. Yet, the truth is elusive, with no clear consensus on the factors that can truly sustain economic growth.

Interestingly, the discussion of growth often overlooks the importance of well-being. GDP, the traditional measure of growth, fails to account for many aspects of quality of life, such as leisure time, environmental beauty, and personal happiness. Innovations like social media have altered how we measure satisfaction and productivity, often providing value that GDP does not capture.

In developing countries, the narrative is slightly different. Many are experiencing growth, partly due to better resource allocation and technological adoption. Historical factors, like colonial legacies, have influenced their economic paths, but issues like market failures and misallocation of resources continue to pose challenges. Yet, there are opportunities for growth by improving how resources are utilized.

Ultimately, the focus should perhaps shift from relentless pursuit of GDP growth to enhancing the quality of life. By addressing health, education, and infrastructure, countries can improve well-being even without rapid economic expansion. This approach might be more sustainable and beneficial in the long run, both for developed and developing nations.

Can We Move Beyond GDP to Truly Measure Quality of Life?

In 2019, the reality of climate change is undeniable, posing significant challenges to global economic growth. The Intergovernmental Panel on Climate Change (IPCC) warns that even a 1.5°C increase in global temperature could devastate coral reefs and cause severe impacts on agriculture and sea levels, disproportionately affecting poor countries.

The 50-10 rule highlights that 10% of the world's population contributes about 50% of CO2 emissions, emphasizing the need for wealthier nations to take responsibility. Even countries like China, the largest carbon emitter, mainly produce goods for consumption in richer countries. As consumption rises, so do emissions, necessitating a shift to sustainable practices.

Abhijit Banerjee's personal experience swimming in the Baltic Sea illustrates the tangible effects of climate change. Warmer waters in recent years contrast starkly with the frigid temperatures of the early 1990s, signaling a broader environmental shift. Poorer countries near the equator, like India, face severe consequences, including more frequent and intense heatwaves, which reduce agricultural productivity and increase mortality rates.

Air conditioning, while a potential lifesaver, exacerbates climate change due to harmful HFC gases. The Kigali agreement aims to phase out these gases, but poorer countries like India face a difficult choice between immediate survival and long-term sustainability.

Despite technological advances, reducing emissions requires significant policy changes and international cooperation. The Stern Review suggests that with deliberate policy choices, it is possible to achieve economic growth while stabilizing emissions. However, this transition is not free and requires substantial investment.

For instance, the Weatherization Assistance Program in the US and energy efficiency initiatives in Gujarat, India, demonstrate the challenges in achieving expected energy savings. Real-world applications often fall short of engineering predictions, indicating that better technologies alone may not suffice; behavioral changes and reduced consumption are also necessary.

The Green New Deal in the US proposes linking climate action with economic justice, creating jobs through green infrastructure while addressing emissions. However, carbon taxes, if implemented thoughtfully to avoid burdening the poor, can incentivize conservation and fund clean technologies.

Ultimately, combating climate change demands a global effort, with richer nations supporting poorer ones in transitioning to sustainable practices. This approach not only addresses immediate health hazards like air pollution but also ensures a healthier planet for future generations.

Abhijit Banerjee's Climate Wake-Up Call: A Global Appeal for Sustainable Action

In Kurt Vonnegut's 1952 novel "Player Piano," a dystopian future is envisioned where machines have replaced most human jobs, leaving people with no meaningful work. This foresight resonates today as technology, AI, and automation advance, causing fears about job loss and inequality. Economists like Erik Brynjolfsson and Andrew McAfee warn that digitization could make many workers obsolete, exacerbating inequality.

For instance, Annie Duflo uses an AI assistant named Fin, who manages her tasks more efficiently than previous human assistants. This shift highlights the potential widespread impact of AI across various jobs, from accountants to taxi drivers. Studies suggest that 45-46% of jobs in the US and OECD countries risk automation. Although some argue new jobs will emerge, there’s no consensus among economists on this.

Historically, automation has displaced workers, similar to the Luddites' resistance to mechanization during the Industrial Revolution. Automation and AI might not necessarily create enough new jobs to offset the losses, particularly impacting low-skilled workers. Research shows automation has already reduced employment and wages in heavily affected areas.

The response to automation may involve policy changes, such as robot taxes, proposed by figures like Bill Gates. South Korea has implemented such taxes to curb excessive automation. However, automation persists due to factors like tax incentives for capital over labor.

The rise of superstar firms and the financial sector has concentrated wealth and increased inequality, particularly in the US and UK. Technological advancements and globalization have created a winner-take-all economy, where a few companies dominate markets. This has led to higher wages for top executives and finance professionals, contributing to the overall rise in inequality.

Cultural changes and policy decisions, like lowering top tax rates, have also played a role. High marginal tax rates on very high incomes could help address inequality by making ultra-high salaries less attractive. This approach has historical precedence and support among some economists and politicians.

The belief in the American Dream and the perception of high social mobility contribute to the acceptance of inequality in the US. However, declining mobility and rising despair among less-educated whites have led to increased mortality and social unrest.

To mitigate these issues, policies must address inequality and support those displaced by technological and economic changes. This includes considering universal basic income, progressive taxation, and effective social safety nets to ensure a fairer distribution of prosperity.

Is "Player Piano" Predicting Our AI-Driven Future of Joblessness and Inequality?

In today's world, expecting markets to always deliver fair outcomes is unreasonable. Government intervention is crucial, particularly in addressing inequality and ensuring people don't have to give up their dignity to survive. While taxing the rich can help, it's not a complete solution. We also need to support the middle class and ensure fair taxation across the board. However, the state faces a legitimacy crisis, with many not trusting the government to manage funds efficiently.

Consider the United States, where tax revenue is significantly lower than in many other developed countries. Raising taxes on the wealthy alone won't bridge the gap, and there's widespread reluctance to increase taxes for average earners. This is partly due to a belief, fueled by economists, that high taxes dissuade people from working—a myth debunked by studies, including a Swiss experiment showing no change in work habits during a tax holiday.

Skepticism towards government isn't just an American phenomenon. In India, farmers' distrust led to the failure of a plan to charge for electricity to curb over-irrigation. Efforts to build trust, like a new pilot program, show promise but face ongoing suspicion. This mistrust often stems from historical grievances and a belief that government interventions benefit elites at the expense of average citizens.

Corruption is another major concern, often overshadowing the potential benefits of government programs. While transparency and accountability can curb corruption, they can also stifle innovation and flexibility within government operations. Yet, the private sector isn't immune to waste either, as seen in mixed results from privatization experiments in education and employment services.

The obsession with corruption can lead to cynicism and inaction, as seen in the United States, where government mistrust hinders necessary tax reforms and expansions of social programs. The solution lies in innovative policy designs that balance effectiveness with political feasibility, as demonstrated by successful conditional cash transfer programs in Latin America, which have shifted public perception on welfare.

Ultimately, the challenge is to overcome the divides of mistrust and create policies that ensure a fair distribution of resources, supporting a vision of the good life for all. This endeavor might be among the greatest challenges of our time, demanding collaboration between governments, NGOs, and the world's brightest minds.

Bridging Trust and Fairness: Lessons from Global Taxation and Governance

In the heart of Lucknow, a city in northern India, stands the Bada Imambara, a colossal monument from the 18th century. It’s neither a fort nor a palace, nor a mosque nor a mausoleum. It was built by King Asaf-ud-Daula to provide work for his starving subjects during a famine. 

The project took longer than expected because workers built it during the day, and the aristocrats destroyed it at night to earn wages without revealing their desperation. By creating "work" (even if it was futile), they allowed the workers to earn wages without directly admitting their poverty.

The tension between cash and care is a focal point in designing social programs. On one side, advocates for Universal Basic Income (UBI) argue that providing cash without conditions respects the recipients’ ability to decide what's best for themselves. UBI is simple and appealing, especially in Silicon Valley, where the fear of technology-induced job losses is prevalent. On the other side, critics worry that unconditional aid could foster dependency and demotivate work.

Globally, programs offering cash transfers are increasingly common, showing positive impacts on nutrition, education, and health without encouraging wasteful spending. Yet, cash transfers often face resistance due to their cost and the belief that they may discourage work. Evidence suggests otherwise, showing that recipients of cash transfers continue to work and often use the money to improve their lives.

In the developed world, particularly the US, social policies are at a crossroads. The idea of UBI is gaining traction, but it may not address the deeper issue of identity and purpose found in meaningful work. Many displaced workers struggle to find new jobs that offer the same satisfaction and community ties as their previous positions. The solution might lie in supporting transitions to new careers while maintaining community ties, rather than relying solely on cash transfers.

Social policy must evolve beyond traditional welfare models, recognizing the importance of dignity, identity, and meaningful work. This requires imaginative solutions, like supporting job transitions, investing in education and care sectors, and fostering community-centered initiatives. By embracing these principles, societies can navigate economic changes without sacrificing the dignity and well-being of their citizens, ensuring progress that is both inclusive and sustainable.

Can Universal Basic Income Preserve Dignity in a World of Rapid Change?

The increasing polarization in our world is evident in political discourse and social issues, driven by personal values rather than facts. Economic challenges like global growth slowdown, trade wars, and inequality are often superficially discussed, and economists' insights are ignored. 

The trust deficit in economists is significant, partly due to poor communication and media portrayal. Economics involves intuition, experience, and trial and error, striving to refine understanding based on new data.

Migration is misunderstood and politically exploited, with exaggerated fears and misconceptions about immigrants. Economic fears about migrants driving down wages are unfounded, and policies should focus on easing migration processes and integration.

Free trade has potential benefits but also creates challenges, particularly for workers in rich countries. Policies to help workers adapt and ensure gains from trade are more evenly distributed are essential.

Racial, religious, and gender-based animus is increasingly shaping elections and policies. Understanding the roots of preferences and addressing policy issues like economic inequality and environmental protection are crucial. Contact with diverse groups can reduce prejudice, and policies promoting integration and respect for individual dignity are essential.

Economic growth has been sluggish since the 1970s, and the focus should perhaps shift from GDP growth to enhancing quality of life. Addressing health, education, and infrastructure can improve well-being without rapid economic expansion.

Climate change poses significant challenges, with wealthier nations needing to take responsibility. Technological advances and policy changes are necessary to reduce emissions and ensure a healthier planet.

Automation and AI are advancing, causing fears about job loss and inequality. Policies like robot taxes and support for displaced workers are needed to address these issues. Addressing inequality requires government intervention, progressive taxation, and effective social safety nets.

Mistrust in government hinders necessary tax reforms and social programs. Innovative policy designs that balance effectiveness with political feasibility are crucial. Overcoming mistrust and ensuring a fair distribution of resources is one of the greatest challenges of our time.

Social policies should balance cash assistance with respect for human dignity. Simplifying access to assistance and supporting job transitions are important for preserving community ties and fostering a society where dignity and opportunity are shared.
