Inside money and outside money

Inside money and outside money is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Inside money and outside money rather than just read about it. In short: In monetary economics, inside money is money issued by private intermediaries (i.e., commercial banks) in the form of debt (credit). This money is typically in the form of demand deposits or other deposits and hence is part of the money supply.

Key takeaways

Inside money and outside money belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Inside money and outside money to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Inside money and outside money from memory before moving on to harder problems.

Reference excerpt

In monetary economics, inside money is money issued by private intermediaries (i.e., commercial banks) in the form of debt (credit). This money is typically in the form of demand deposits or other deposits and hence is part of the money supply. The money, which is an asset of the depositor but coincides with a liability of the bank, is inside money. Outside money is money that is not a liability for anyone "inside" the economy. It is held in an economy in net positive amounts. Examples are money that is backed by gold, and assets denominated in foreign currency or otherwise backed up by foreign debt, like foreign cash, stocks, or bonds. Typically, the private economy is considered as the "inside", so government-issued money is also "outside money". Inside money is thus a liability (equivalently a negative asset) to the issuer, so the net amount of assets associated with inside money in an economy is zero. Most money circulating in a modern economy is inside money.

Worked examples

Example 1 — a first encounter with Inside money and outside money

Start with the simplest possible case. Write down what Inside money and outside money claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inside money and outside money before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inside money and outside money ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inside money and outside money

In research: Inside money and outside money appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Inside money and outside money in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Inside money and outside money is common in secondary-school and first-year university syllabi. It links to neighbouring topics Monetary economics, Money stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Inside money and outside money outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
