This course provides an overview of basic microeconomic theory and applies it to business decision-making. In particular, it will present the main principles of microeconomics from the perspective of strategic behaviour. The course draws on examples from the business world to illustrate the practical relevance of the models used.
This course provides a thorough and contextual perspective on various forms of macroeconomic policymaking. In addition to looking at how monetary and fiscal policy can be used to manage the domestic economy, we will take an international approach to various forms of economic crisis. By the end of this course students will be able to critically engage with some of the key indicators that may help to predict a currency crisis, and relate this to famous historic cases. We will look at the role played by international institutions during sovereign debt crises, and gain experience at identifying, summarising, and communicating relevant data.
How can I use data to understand my organisations situation and performance?
From 2006 – 2010 I taught a Quantitative Methods course at ESCP Europe. I enjoyed it immensely and got great feedback from students. Since then I’ve continued to gather material but realise that no-one gets to see it. So I’ve created an online course.
The course should be of use to anyone with an interest in an MBA level education, and I have attempted to supplement my own presentations with links to some exceptional online resources.
The rest of this page contains some further resources and links.
If you want to start at the very beginning then take my Numeracy Skills Bootcamp, which covers Fundamentals of Mathematics, some Practice Tests, and a discussion of Gender Differences & Mathematics. I also suggest my content on Collecting and Presenting Data.
Textbook
I hope you find the online course useful, but I am also a fan of the old fashioned way. The course ties in to the following textbook:
It is a very good one: well written, full of examples, and plenty of opportunities to test yourself. You could do a lot worse than simply order it now and then work your way through it.
I’m also intrigued by “Calculus Made Easy“, by Silvanus Thompson. It’s antiquated in format but highly directed toward simplifying concepts and engaging with the reader. Statistics Done Wrong also looks fun.
Pop analytics
I believe that a good way to prepare for a subject is to read a book that is captivating. Something that stimulates your interest and encourages you to dig deeper. There are lots of bestsellers that have attempted to communicate mathematical ideas to the educated layperson. My favourite 6 are these:
If you really need to develop your QM skills then I would recommend you follow the HBS one instead of mine. However I found it pretty dull and failed to complete it. I’m hoping that by providing a mixture of content you will find mine more enjoyable.
Daniel Kunin has a wonderful website called “Seeing Theory“, which allows users to visualise basic concepts in statistics. I’ve integrated links into the course below.
I believe that the best way to internalise the key concepts in this course is to conduct a replication exercise. These have become increasingly common as ways to apply the concepts covered, and test a students knowledge retention. To be honest though I am yet to find any really good examples of statistical tests that companies have utilised, and for which the underlying data set is available.
In their textbook, “Modern Principles: Macroeconomics”, Tyler Cowen and Alex Tabarrok present a good exercise to replicate a Solow Model. My (flawed) attempt to combine two of their problem sets is here:
Whilst I continue to look for potential replications, one option is to focus on some controversial statistical debates. These are also good ways to go deeper into the theory, and fully appreciate the link between theory and practice.
You should now be a savvy consumer of statistical analysis and passionate about good data management. I recommend that you treat yourself to the following tome:
This memo summarises some of the key insights from the literature on transitional economics. It focuses on the experience of countries in Central and Eastern Europe who engaged in their reform programmes following the collapse of communism.
On August 9th 2020, Belarus went to the polls. The people voted (most of them, probably, for change); and yet the President remains in power. This policy brief provides a summary of what happened and an analysis of why.
I was a signatory to an open letter dated August 19th 2020 and addressed to the Belarusian authorities on behalf of concerned economists.

55 Broadway, SW1H 0BD
This is a grade 1 art deco building near St James’ park, originally home to the London Underground. It’s not particularly tall (it’s only slightly bigger than Big Ben, and half the height of St Paul’s Cathedral) but given that it has a steel frame it is not only a skyscraper, but London’s first! (It doesn’t look like a skyscraper, but the stone encasing provides no structural integrity. Sadly, it closed in January 2020.
If you visit, try to spot the naked sculptures, Night and Day, on the outside of the building. (For controversy on this, see here).
HM Treasury, SW1A 2HQ
The Treasury is responsible for public finance and economic policy of the UK. It is located within the Government Offices in Great George Street, near Parliament Square. It has a large internal courtyard and the basement is home to the Churchill War Rooms (part of the Imperial War Museum).
Fun fact: It served as the headquarters for MI6 in the Bond movie, Spectre, and was the starting point of the street race in Fast And Furious 6.
11 Downing Street, SW1A 2AB
Next door to the most famous address in the UK (10 Downing Street is the government headquarters and traditionally the private residence of the Prime Minister), 11 Downing Street is the official residence of the Chancellor of the Exchequer. This is the equivalent of a “Minister of Finance”, which is the person responsible for fiscal policy.
Fun fact: Because the private living space is larger at no. 11 than no. 10, when Tony Blair became prime minister in 1997 he decided to live there instead. Every subsequent prime minster has done the same thing.
Established in 1694 this is one of the oldest banks in the world and a model for central banks. It was nationalised in 1946. It has a monopoly on producing banknotes in England and Wales, and is responsible for the conduct of UK monetary policy.
There is an excellent museum in the basement, and several online exhibits, including this one on banknotes. The basement also houses the Bank of England vaults, which contain over 400,000 bars of gold.
Physical marketplaces are important cultural artifacts that demonstrate the importance of economic exchange for the pace and improvements of everyday living. And as Rachel Black said in her ethnographic account of Turin’s Porta Palazzo, “What other public spaces still bring together such an important cross-section of a cit’s population? What places allow for open discussion of just about any topic?” (2012, p. 38-39)
This tour can be conducted on foot, but links to virtual resources are also provided.
Portobello Market, W11 1AN
The world’s largest antique market, in the famous Notting Hill. It’s main trading day is Saturday but the area also contains numerous permanent shops. Follow on Instagram to see details of virtual fashion markets on Fridays.
Brick Lane Market, E1 6QR
Containing bric-a-brac as well as fruit and vegetables, Brick Lane market is part of London’s East End and close to the world famous cluster of curry houses. The market is is open on Sundays and can get very busy! For more information see here or here.
Smithfield Market, EC1A 9PS
Smithfield Market is technically called “London Central Markets” and is located in Farringdon. It is one of the largest wholesale meat markets in the world and the site has hosted livestock for over 800 years.
Fun fact: Scottish revolutionary William Wallace, otherwise known as “Braveheart”, was killed at Smithfield in 1305.
Borough Market, SE1 1TL
Borough Market is one of the oldest and largest food markets in London, dating back to the 12th century. The present buildings were built in the 1850s and house an eclectic mix of speciality foods. Open Monday – Saturday.
The London Metal Exchange (LME) originates from 1571, but was formed in 1877 and moved to its current location in 2016. It remains one of the few physical trading floors for a major commodity market – activity is conducted within an open outcry “ring”, which gets its name from when traders would mark out a ring using chalk on a coffeehouse floor. For more on its history see here.

Many consider inequality to be a key social problem, and yet economics is all about delving beyond intuitions. Do we have good data on what has happened to inequality over time? What type of inequality matters? Is there an important trade-off to consider when confronting inequality? The answers to these questions may be controversial, but they are relevant and important.
Here is a thread containing 10 books about inequality:
10 Great books on Economic Inequality 1) Inequality – Tony Atkinson Absolutely THE book on inequality and what can be done about it. Atkinson was a giant in the profession and this book reflects this, the length-insights ratio of this book is amazing. pic.twitter.com/Vf0W21VurM
loads of the objections people have to inequality, if there is any truth to them, are probably actually objections to perceptions of inequality, which may be more driven by media coverage than reality. If that’s true, then trying to reduce inequality in fact is a waste of time — you should try to get the media to talk about it less instead
My view of the inequality debate is informed by “Fast” Eddie Felson, from ‘The Hustler’,
Vincent Geloso has challenged some of the work done by Gabriel Zucman. You can read more here:
Thread: Let us be clear — the work of Gabriel Zucman should be taken with a major/huge grain of salt. Largely because he and his colleagues have been sloppy as hell. I will not mince words here and list the litany of sloppiness #econtwitterhttps://t.co/4icOSMcZc7
On initial inspection this graph looks highly dubious:
The selection of countries is suspicious (why exclude countries that have more income inequality than the US, and why include Finland but not Singapore?)
The “Index of health and social problems” looks arbitrary and prone to manipulation
However I’ve not been able to find the actual source yet. I assume it comes from ‘The Spirit Level‘, which I believe has been quite firmly debunked.
Oxfam are also renowned for using dodgy statistics. For example:
Here is an article from Marginal Revolution providing context and assessment of the tribunal that found Next had broken the Equality Act of 2010
Aside: Sometimes I’m asked what I really think about inequality. Really? That the there is no ethical basis for being concerned about inequality per se. In fact, the best argument to take it seriously is because low educated and xenophobic natives, who have hit the jackpot in where to be born, hold civilised (i.e. cosmopolitan) society to ransom by threatening extremism of various sorts and civil disorder unless their concerns are met. Ideally, we prevent all that from happening by ensuring nominal income stability and productivity growth. But there’s no moral basis for “equalising” arbitrary distributions. Our moral concerns should be focused on eradicating poverty and destitution; and ensuring a competitive market economy that rewards wealth creation and limits rent seeking. If forcing Charles Koch to emigrate improves your metrics of success, then I demur.
This is also something that Dracula noticed when he encountered a “normal” modern house:
I’ve been a nobleman for 400 years. I’ve lived in castles and palaces among the richest people of any age. Never….never! Have I stood in greater luxury than surrounds me now. This is a chamber of marvels. There isn’t a king, or queen or emperor that I have ever known or eaten who would step into this room and ever agree to leave it again. I knew the future would bring wonders. I did not know it would make them ordinary.
I think it is useful to do some basic back of the envelope calculations when thinking about a potential wealth tax. There are around 150 billionaires in the UK with total assets of around £500bn. A 1% wealth tax would therefore raise £5bn and a 3% one would raise £15bn. The UK budget deficit runs at around £10bn per month, or over £120bn per year. (The NHS spends around £190bn per year.)
Therefore even if all of those 150 billionaires decide to stay a 3% wealth tax would fund approximately 1/8th of our debt interest payments.
Recently, Norway increased their wealth tax to 1.1%. According to a report in The Guardian, “More than 30 Norwegian billionaires and multimillionaires left Norway in 2022… This was more than the total number of super-rich people who left the country during the previous 13 years, it added. Even more super-rich individuals are expected to leave this year because of the increase in wealth tax in November, costing the government tens of millions in lost tax receipts… Many have moved to Switzerland, where taxes are much lower”
Here is the reason I’m concerned about the link between inequality as a public policy issue and central bank digital transformation:
We realize it’s difficult to pay your wealth tax when much of your wealth is in the form of illiquid assets. As a result, we’ve deducted the amount from your CBDC balance, which is now negative and subject to the central bank’s borrowing rate.
I largely share Martin Wolf’s (2023, p. 283) criticisms of a universal basic income (UBI) in that by being so intentionally ill targeted it creates too much of a waste of limited public funding – “A UBI at a high enough level to render targeted assistance to those who are vulnerable, needy, and deserving would be unaffordable, while a UBI that is affordable would benefit many people who do not need the money and fail to benefit important services and people who need more than they have now.” I prefer a moderate income tax with generous allowances and incentive compatible welfare payments.
We can think of the state as an “insurer of last resort”, with its access to taxation permitting favourable terms for mitigating risk (p. 274). By being able to compel people it also avoids the “adverse selection” problem that befells individuals in particular need. This helps to explain the main economic justification for a well functioning welfare state (p. 276):
Incomplete private insurance
Incomplete capital markets
Note though that improving the market in those two areas would reduce the need for widespread social protection.
Luxury
I was very disappointed when Rimowa were sold to LVMH and switched from being a high quality travel company to part of a luxury brand. As Michael Story said,
As per Mary Douglas I view high status consumption goods as part of our need to separate ourselves from others, and signal which groups we belong to. I don’t play those games (at least not on those margina) and think it’s a bit of a waste of resources to do so. But I respect people who admire beauty, design, and the pursuit of aesthetics. Live and let live, I say. But tax the hell out of them…
Labour markets
In terms of workplace diversity and employment discrimination, one of the most famous academic economists is Roland Fryer.
Recommended audio:
“Roland Fryer on Race, Diversity, and Affirmative Action” EconTalk, September 4th 2023 – Fryer explains how the study of discrimination can be approached in three main ways: preference based (e.g. Gary Becker); information based (e.g. Kenneth Arrow); and structural (i.e. sociologists). He summarises his career, talks fondly about the influence of his grandmother, and the importance of combining intuitive wisdom with rigorous data analysis. His main point is that wage discrepancies are not necessarily discrimination, and companies often lack the curiosity or capability to use the data at their disposal to really understand the problems they face. This helps to explain why the benefit of diversity training is zero, and the impact of mandatory diversity training is possible negative.
Slavery
For an overview of the debate surrounding the role of slavery in the rise of the West see:
“Claudia Goldin on Inequality“, Conversations with Tyler, Oct 6th 2021 – this conversation focuses on gender inequality and the labour market in particular, and although some of the discussion is aimed at graduate students they pose some excellent questions to reflect on.
“Thomas Piketty on the politics of equality“, Conversations with Tyler, April 20th 2022 – Tyler challenges Piketty on some of the political economy arguments relating to progressivism and does a good job putting Piketty’s work into a history of economic thought perspective.
Ep. 28: Vincent Geloso — Should We Care About Inequality?, The Curious Mind, February 12th 2020 – Vincent talks about which types of inequality are most important to reduce and discusses some of the academic literature that has contributed to our understanding of the issue. His main claim is the need to build a dashboard and avoid overly simplistic explanations or solutions.
Recommended film:
You can see the trailer to Parasite here:
I also recommend the 2021 BBC series Chloe. As this Guardian review demonstrates, when it says “I hope she gets away with everything”, some viewers can actively root for despicable behaviour if it’s presented as a commentary on inequality.
During the class I say that it is inconceivable to have an American movie that portrays wealthy people in a positive light. Potential counter examples include:
The Dark Knight Rises (2012) – the good guy is a billionaire, the police are heroes, and Bane occupies Wall st… I’m not sure the Batman is a positive depiction of wealth, but it’s certainly a very rare example of a movie that is more right wing than left wing.
One Day (2023) – Dexter is obnoxious and his wealth and priviledge is not portrayed in a positive light, but we certainly sympathise with him and, as this Guardian review points out, his “wide-boy charisma and frightful yet endlessly forgivable privilege are perfectly pitched; I forgive him a thousand times. His poshness is neither glossed over nor glamorised; it is simply integral.”. Dexter’s dad is a good man, who we sympathise with, and we don’t hold his wealth against him. That’s something, I guess. (Note this isn’t American, or a movie, but I’m open to anything!)
Saltburn (2023) – this film is a challenging watch but very good (the line “she’d do anything for attention” is perhaps one of the funniest I’ve ever heard). If you’ve read Engleby then I think you lose a large part of its power and originality, and if you understand the Solow growth model you may be confused by the ending. In terms of its implication for inequality, you do sympathise with the rich, and it sort of parallels Parasite’s warning about trust and naivety. But Oliver isn’t poor (despite his bad accent, Prescott is fine!), and the Catton’s aren’t portrayed as having earned their wealth. They are not horrible people but we do laugh at their buffoonery and aren’t asked to respect them. Felix isn’t atrocious but he’s manipulative. Like Parasite, it shows the rich as victims of those less fortunate, and unlike Chloe we’re not supposed to cheer them on. But it doesn’t portray wealthy people in a positive light.
Finally, if you like the plot device from Parasite, with people appearing from underground captivity, confronting a confusing situation as a result of odd costumes, leading to violence and mayhem… then I recommend Emir Kusturica’s Underground (1995):
Learning Objectives: Survey the latest empirical work on inequality and relate this to wider social issues.
Are we running out of ideas? Freakonomics, November 2017 – the key points are to consider whether productivity is happening but isn’t being captured by GDP due to spillovers
According to Max Grossman, as of 2021 half of all scientific papers that had even been published had come in the last 12 years, and yet much less than half of scientific progress had happened in that same period.
Here’s a great image showing a long-term timeline of technology (but notice the gap between smartphones and Now):
Here is a video showing the opening of the Empire State Building:
And don’t forget just how amazing it was when people saw the iPhone for the first time:
For more on whether Jeanne Calment really was the oldest person ever, see Wikipedia. Saul Newman is a demographer who has found that the places that have lots of people living over the age of 100 tend to be riddled by clerical errors and pension fraud – he won an Ig Nobel in 2024. This chart shows that once birth certificates became widely adopted far fewer people claimed to be very old.
Here is The Economist on how claims of people living to a great age decline when birth certificates are introduced.
As Alec Strpp says, “Areas of the world with people claiming to be 110+ years old are actually just places with poor record keeping and a lot of pension fraud.”
Isn’t it weird how you used to be able to easily tell when a TV series was set from the fashion? And yet long running recent shows are much harder to date. For example,
Consider the following:
I was saddened to learn recently that same amount of time had passed between the first human airplane flight and the first human spaceflight as between the first spaceflight and 2018 (see here).
Here is a good defense of the importance of aviation:
“It has offered people the opportunity to migrate from one country to another It lets them return home to visit their families. It has provided jobs. Driven innovations in new technologies. It has made our societies more diverse and multicultural and has allowed us to experience the beauty of other countries. these are experience I want everyone in the world to have access to” (Ritchie, 2024, p.99)
The lecture provided some pessimistic views on transformative breakthroughs. But every now and then I notice the power of steady, incremental progress. For example:
Textbook Reading: Chapter 1 (Section 1.2, pp. 16-29)
The purpose of this session is to realise that value comes from satisfying people’s needs, and that this leads to a broad and insightful realisation that:
Competition is when anyone else tries to satisfy the same customer needs that you do.
Innovation is trying to find better ways to satisfy your customers needs.
Entrepreneurship is successful when you understand your customers needs better than they do.
Steve Job’s famous advice was to not listen to your customers. This is in contrast to Tyler Cowen’s “law of interesting content” – which is that interviewers should have the conversation that they want, not what they think their listeners want.
I think it is incorrect to say that the reason diamonds are more valuable than water is because they are scarcer. This would be using the term “scarcity” to refer to a relative amount of present consumption, but that is obtuse. We normally use scarcity as a collective assessment of the availability of a good. In other words, there is no such thing as personal scarcity.
Learning Objectives: Link a thorough concept of value with implications for competition and innovation. Derive demand curves.
Cutting edge theory: Jobs to be done
Focus on diversity: Economists typically take preferences as given, but we can provide a theory of demand reflecting “the individual’s commitment to an intelligible universe” (p.52), where goods are considered to be a visible reflection of culture. Mary Douglas (1921-2007) was one of the world’s most admired social anthropologists, and her 1979 book, ‘The World of Goods’, provided a rich and compelling illumination of consumption patterns.
