Economic analysis can be useful for investors, business, and government policy makers. Yet, economic concepts can seem complex because of all the bars, charts and technical jargon involved. In this book, Charles Wheelan explains powerful key concepts in layman terms, helping us to understand the fundamentals of the economy at work. In this free Naked Economics summary, you’ll get a brief synopsis of some of the key economic concepts and fundamentals in the book including:
• How Markets Work
• The Use of Incentives and Disincentives
• The Roles (and Inefficiencies) of Government
• The Economics of Information
• Human Capital
• Financial Markets (including financial instruments and investment principles)
• Politics, Economic Indicators and Globalization
How Markets Work: 2 Key Assumptions
There are 2 key assumptions which explain pretty much how the world works, and why market mechanisms are so powerful.
1. Individuals Act to Maximize Utility
People act to make themselves as well off as possible, i.e. they maximize their utility. The meaning of utility however varies from person to person. A key message here is: it does not make economic sense to impose our preferences on others. For example, someone in a developed country will see the issue of deforestation very differently from the villager who is cutting down a tree to pay for food and medication for his sick and starving son. This disparity is often influenced by income inequality, as those with more resources may prioritize long-term goals like environmental conservation, while those with fewer resources may focus on immediate survival needs.
Wheelan also explains how we make decisions with imperfect information, weigh trade-offs, and define “cost” (which is more than just cash). Generally, when costs decrease, we consume more of something and vice versa.
2. Firms Act to Maximize Profits
Firms can refer to a person (e.g. a doctor, artist) or a multinational private company. The second economic assumption is that firms aim to maximize profits (i.e. revenue less costs). Individuals will go where they are paid the most for their talents, and firms will do businesses that make them the most money in the long run. Wheelan explains how entry barriers and prices influence behaviours, shaping not only markets but also decisions in daily life, such as career choices, consumer spending, and resource allocation.
How the Market Works?
The 2 assumptions above explain more or less how the world works:
• The market economy can make our lives better, because the only way firms make profits is by delivering what we want to buy.
• Prices are used to allocate scarce resources, based on who is willing the pay the most (in terms of money, time etc.).
• Every market transaction makes all parties better off. However, since we define utility differently, we may not always understand the choices made in other parts of the market.
Incentives & Disincentives
People react to incentives and disincentives. The right incentives align the interests of various parties so they act towards a common desired outcome.
The book explains how these 4 factors—Rewards, Self-Interest, Competition and Taxes— influence human behaviour. Our 12-page Naked Economics summary provides a detailed overview on these factors.
Government & the Economy
Good government is essential to a strong economy, productive market while poor government can lead to the demise of an entire economy.
The Government can be your Friend
Generally, governments can enhance the productive capacity of the economy to make us better off through government spending and the establishment of effective government institutions.
• Legal Frameworks. Governments set the rules, without which countries and markets cannot function. This includes defining and protecting property rights, and lowering the cost of doing business.
• Correcting Externalities. An “externality” is the gap between the private cost and the social cost of a specific behaviour (e.g. littering, drunk-driving, smoking etc.). When the gap is large, individuals tend to do things that make them better off at the expense of others.
• Public Goods. Governments raise our collective utility by providing public goods (e.g. parks, law enforcement, lighthouses) that we can’t purchase for ourselves, and wouldn’t otherwise be provided by the private sector.
You can get more details and examples on each of these roles in our complete Naked Economics summary, including Wheelan’s recommended principles for public goods providers.
Government Involvement can generate Negative Outcomes
While good government intervention is essential for markets to function, some government activities are less effective and may even generate negative outcomes. These include the limitations and potentially-adverse impact on wealth distribution, resource allocation, restrictions from regulations and setting the “right” level of taxes. The role of government is to create and enforce policies that ensure market efficiency, fairness, and stability, but when intervention is misaligned or overbearing, it can distort economic incentives and hinder growth. Ensuring that government intervention supports rather than disrupts market performance is crucial for maintaining long-term economic health.

Economics of Information
In economics, the bars and charts are often drawn with the assumption that all parties have perfect information. In the real world, no one has perfect information, and we make decisions with and without them. Part of economics is understanding how people acquire information, how they use it and how they make decisions. Market influence plays a significant role in shaping those decisions, as companies and individuals respond to supply, demand, and pricing signals. Additionally, the power of market is a key force driving economic behavior, as it determines how resources are allocated and influences the flow of goods, services, and capital. Our 12-page Naked Economics summary elaborates on how people make decisions when they lack information, why knowledge offers a real economic advantage and why brands have an economic value.
Productivity & Human Capital
Human capital is the combination of the skills in a person, including education, work experiences, charisma, vigor, talents etc. Resources invested in human capital today will yield a rate of return in the future, and historically, the pie has been growing, with more jobs being created than lost. Find out more from our full summary about how investments in human capital can lead to better quality of life and a larger pie in the long run.
Financial Markets
Financial markets function like all other markets – capital flows to where it can earn the best return, given available information.
Financial Instruments & Investment Principles
All financial instruments are built on 4 basic needs – to raise capital, protect/ grow wealth, insure against risk, and speculate.
Our complete Naked Economics summary touches on these 4 factors, including Wheelan’s 4-point investment principles to help you get predictable returns on your investment. His advice to the average investor is this – you can’t beat the market and you shouldn’t try, and he explains why in this economics book.
The Power of Organized Interests
Despite our growing knowledge about public policy, good policies often don’t get implemented due to politics and interest groups. Generally, interest groups lobby for what they want (e.g. subsidies, tax breaks) or what they don’t want (e.g. protection from new technologies and international trade).
When it comes to interest group politics, it’s better to be small – the favours given by the system is spread over a small number of people (making it more lucrative for each one), while the costs are spread over a large number of people (making it smaller, less painful and less prone to resistance). This dynamic can also influence fair trade policies, where small groups of producers or business owners may lobby for favourable terms, while the broader population may not feel the immediate impact, often making it harder to implement fairer trade practices on a larger scale.
Economics & Economic Indicators
1. Key Economic Indicators
To measure economic progress, we need to first define progress. The book covers many economic indicators, and we zoom in on a few key indicators in our complete Naked Economics summary, including Gross Domestic Product or GDP (which measures a country’s production), unemployment (the percentage of workers who want to work but can’t find jobs), cost of living (the time we must work, in order to live), budget deficit/ surplus (how much the government is spending relative to what it collects), and current account surplus/ deficit (how much we earn from the rest of the world relative to how much they earn from us) and economic growth (the long-term increase in a country’s output of goods and services). These indicators often highlight economic issues, such as wealth inequality, inflation, and fiscal imbalances, which are critical for understanding the broader health of an economy.
2. Recessions
All major economies, be it rich or poor, tend to move through cycles of recession and recovery. Recessions usually (i) stem from a shock to the economy (e.g. collapse of stock market or property bubble), and (ii) involves more than 1 cause. The sustained drop in income makes people spend less, which spreads the economic damage to other markets. Our complete summary takes a look at how recessions work, using the 2007 recession as an example.
3. The Federal Reserve
The US Federal Reserve (“the Fed”) controls the money supply and the credit tap for the US economy. It affects not only the US economy but the global economy. In our 12-page Naked Economics summary, you’ll get a great overview how economic tools like interest rates and monetary policy work, and how the government can use fiscal policy and monetary policy to stimulate the economy.
4. Currencies and Exchange Rates
Changes in exchange rates make foreign goods cheaper or more expensive. There’s nothing inherently good or bad about a strong or weak currency, since an undervalued currency promotes exports and a stronger currency increases purchasing power. The book explains different ways to value currencies against one another, including the Gold Standard, floating exchange rates, fixed exchange rates, and pegging your currency to another currency. External factors, such as inflation rates, market conditions, interest rates, political stability, and global economic conditions, also play significant roles in currency values, influencing trade balances, investment flows, and overall economic health.
5. Trade & Globalization
Finally, our complete Naked Economics summary looks at the various economic bases upon which international trade is built. Wheelans shares why global trade benefits all countries in the long-run (as opposed to protectionism, which creates the opposite effects).
