Good Value

Good Value 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 Good Value rather than just read about it. In short: Good Value: Reflections on money, morality and an uncertain world is a 2009 book by Stephen Green, the Chairman of HSBC, written in response to the banking crisis. He describes the book as "a journey of unfinished exploration" and suggests that deep personal and corporate values are essential for a sustainable revival of business.

Key takeaways

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

Reference excerpt

Good Value: Reflections on money, morality and an uncertain world is a 2009 book by Stephen Green, the Chairman of HSBC, written in response to the banking crisis. He describes the book as "a journey of unfinished exploration" and suggests that deep personal and corporate values are essential for a sustainable revival of business. He suggests that "We need to be able to look ourselves in the mirror and ask two questions about our role in the global bazaar: how is what I am doing contributing to human welfare? And why am I specifically doing it?"

Reviews and comments Chris Blackhurst in the Evening Standard described it as "an intensely intimate, refreshing and at times searing read" and said it "should be required reading in business schools and boardrooms" Ruth Gledhill in The Times says "is a detailed analysis of the ethical and moral issues arising from the present economic crisis. It is not remotely didactic and it is mercifully free from the self-righteous pomposity that you might expect from a banker who is also an ordained clergyman." Lionel Barber in the Financial Times says the book "wrestles with the demands of individual responsibility and the market but it is set in a broader economic and historical context. Green’s ambition is to make the case for globalisation as an inevitable, progressive force and as a human phenomenon." Boyd Tonkin in The Independent raises two cheers for a book that "strides fluently between T.S. Eliot and Karl Marx, Goethe and Camus, Adam Smith and the Prophet Isaiah, Amartya Sen and Teilhard de Chardin, Puccini's operas in Beijing and Rajasthani paintings at the British Museum" The Wall Street Journal described the book as "an unusual and thoughtful disquisition on how to conduct oneself in a world of high finance and ambition, in ...the global bazaar."

Worked examples

Example 1 — a first encounter with Good Value

Start with the simplest possible case. Write down what Good Value 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 Good Value 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 Good Value 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 Good Value

In research: Good Value 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 Good Value 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: Good Value is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 non-fiction books, Business books, Economics and finance book stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Good Value 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.

Frequently asked questions

What is Good Value in simple terms?

Why does Good Value matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Good Value?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
