Market failure is one of the most important ideas in the whole of economics. It is exactly where we are headed in Episode 004 of Mission Control.
Every day, prices rise and fall, shops stock more of some things and less of others, and entire industries expand or shrink, seemingly on their own. Behind all of it is a single, quietly powerful mechanism: the market. Left alone, it can coordinate the choices of millions of people without anyone being in charge. However, it does not always get things right. Pollution goes unpunished, useful things go unbuilt and buyers and sellers sometimes know very different things about what they are trading.
In this latest episode from Apollo Scholars, Matt and Lucy explore how markets are supposed to work, where that system starts to break down and what, if anything, governments can do to fix it.
After exploring the Cold War in Episode 004, we are turning to a completely different subject: Economics.
How do prices actually get set? Why does a market sometimes fail to deliver what society actually needs? And when a government steps in to fix a market failure, does it actually make things better, or does it just create a different set of problems?
That is the story we are exploring in Episode 004.

Welcome to Mission Control
Mission Control is the educational podcast from Apollo Scholars, exploring the ideas, events and stories behind the subjects you study.
Across the series, we will explore History, Economics, Business, English Literature and English Language, breaking down complicated topics and making them easier to understand, remember and connect together.
Mission Control is not just about revision.
Whether you are studying for an exam, interested in economics, or simply want to understand why your concert ticket, your coffee, or your energy bill costs what it does, each episode is designed to tell a story first.
After all, economics is not just about memorising diagrams.
It is about understanding why.
Markets and Market Failure
For our third full episode, we are tackling one of the foundational ideas in economics: how markets work, and why they sometimes fail.
Every market, from a village stall to a global commodities exchange, is really just people responding to prices. Buyers try to get the most for their money. Sellers try to make the best return on what they produce. When it works, this simple system is remarkably good at allocating scarce resources without anyone directing it. When it does not, the results can be wasteful, unfair, or even dangerous.
We have divided the story into six chapters, taking you from the very first assumptions economists make, through to what happens when governments try to step in and put things right.
Thinking Like an Economist
Before any of the diagrams and formulas, economics starts with a strange admission: economists cannot run controlled experiments on the real world, so they build simplified models instead. This chapter explores the assumptions behind those models, the crucial difference between a positive statement of fact and a normative statement of opinion, and why two economists can look at the same evidence and reach completely different conclusions.
Scarcity, Choice and Opportunity Cost
At the heart of economics is a simple problem: wants are unlimited, but resources are not. This chapter looks at scarcity, the difference between renewable and non-renewable resources and opportunity cost. It also introduces the production possibility frontier, a single diagram that captures the trade-offs facing every household, firm and government.
Specialisation, Trade and Economic Systems
Why does one factory make thousands of pins a day when one worker alone could barely make a handful? This chapter explores the division of labour, the advantages and risks of global specialisation and trade, the four functions of money and the age-old argument between free market, command and mixed economies.
How Markets Work: Demand, Supply and Price
This is the engine room of the episode: demand, supply, elasticity and the price mechanism that quietly rations goods, incentivises producers and signals information across an entire economy. We also take a detour into behavioural economics, questioning the rationality of consumers.
Market Failure: When Markets Don’t Work
Here is where the story turns. Left alone, markets can fail to account for pollution, under-provide things like street lighting and clean air and misallocate resources when one side of a deal knows more than the other. This chapter unpacks externalities, public goods and information gaps, the three main causes of market failure, with real, memorable examples of each.
Fixing It (and Breaking It Again)
Governments have a whole toolkit for correcting market failure: taxes, subsidies, price controls, regulation and more. However, intervention does not always work as intended. This final chapter explores government failure, using real historical examples of policies that backfired. We also ask the question every economist eventually has to answer: is this fix actually worth it?
Can We Really Trust the Market?
One of the biggest questions in economics is not simply whether markets work, but when we should trust them, and when we should not.
Is the price mechanism really the best way to allocate a society’s resources?
Should governments intervene every time a market produces an unfair or wasteful outcome?
Or can government intervention itself end up doing more harm than the market failure it was meant to fix?
The answer is more complicated than any single side of the debate suggests.
Externalities, public goods and information gaps are all genuine reasons markets can fail. However, taxes, subsidies and regulations all carry their own risks, from unintended consequences to the sheer cost of running them.
That is one of the central questions we explore in this episode.
Listen to Mission Control Episode 004
Markets sit behind almost everything we buy, sell and argue about, from concert tickets to carbon emissions.
This episode explores how they are supposed to work, where market failure creeps in and what governments can realistically do about it.
In Episode 004 of Mission Control, we explore that question across six chapters.

Welcome to Mission Control
Economics can feel like a subject of abstract diagrams and equations.
However, once you stop seeing it as a set of rules to memorise and start seeing it as a story about real choices, real prices and real consequences, the bigger picture begins to emerge.
From the assumptions economists make, through scarcity, trade and how prices are set, to market failure and what governments can, and cannot, do about it.
Six chapters. One story.
Welcome back to Mission Control.
