Hello, I'm Leath

/leɪθ/ — rhymes with faith

I'm an economist working in regulatory finance at Smart DCC, the company running Britain's smart meter data network. Previously, I spent six years at the British Business Bank, where I helped secure over £1bn in government funding and led programmes that supported over a million businesses during the pandemic. I also serve as a Non-Executive Director at Wenta, a social enterprise supporting small businesses, and sit on the Council of the Society of Professional Economists.

I grew up between Iraq and Austria, studied economics in Vienna and Nottingham, and now live in London. This site is where I share what I'm reading, thinking about, and working on. I'm interested in economics, regulation, business, language, history, and philosophy.

Books to Read

9 items
  • The Ride of a Lifetime — Robert Iger
    Recommended by three people I respect. Want to understand how Iger navigated Disney's digital transformation and media disruption.
  • Measure What Matters — John Doerr
    OKRs keep coming up in conversations about organisational effectiveness at Wenta. Want to understand the framework properly.
  • Good Strategy Bad Strategy — Richard Rumelt
    A counterweight to all the strategy frameworks floating around. Rumelt's critique of corporate strategy is sharp and necessary.
  • The Goal — Eliyahu Goldratt
    Theory of Constraints is everywhere in operations thinking. Want to understand it through the original narrative novel.
  • How to Take Smart Notes — Sönke Ahrens
    About the Zettelkasten method. My current note-taking feels scattered; this might offer structure.
  • The Structure of Scientific Revolutions — Thomas Kuhn
    Paradigm shifts. Fundamental to how I think about regulatory change and disruption.
  • Playing to Win — A.G. Lafley & Roger Martin
    Strategy from the Procter & Gamble perspective. Practical and grounded in real competitive dynamics.
  • The Art of Action — Stephen Bungay
    Combines Boyd's OODA Loop with practical business strategy. Been meaning to read this for three years.
  • Permission Marketing — Seth Godin
    Written in 1999 but still relevant to how fintech thinks about customer relationships and permission to engage.

Favourite Thinkers & Writers

10 items
  • Tyler Cowen
    His ability to connect economics to culture, food, and everyday life is unmatched. Marginal Revolution is a daily read.
  • David Perell
    Taught me that writing online is the most underrated professional skill. His essays on technology and culture are sharp.
  • Nassim Nicholas Taleb
    Antifragile changed how I think about risk in regulation and finance. Provocative but consistently right about tail risk.
  • Adam Smith
    More than just the invisible hand. His work on moral sentiment and social behaviour is deeper than most people realise.
  • Isaiah Berlin
    On pluralism, freedom, and the conflict between values. His essay on Herzen shaped how I think about liberty and tradeoffs.
  • Friedrich Hayek
    The Road to Serfdom is overrated, but his work on knowledge problems and dispersed information is fundamental to regulation.
  • Paul Graham
    His essays on startups, technology, and writing shaped how I think about progress. Clear thinking expressed simply.
  • René Girard
    Mimetic theory. Once you understand that we desire what others desire, you can't unsee it in politics, markets, and culture.
  • Yancey Strickler
    On creative independence and how to fund the work that matters. His writing on patronage and economics of culture is original.
  • Hannah Arendt
    On totalitarianism, power, and the political. Dense but revelatory about how societies can lose freedom slowly.

Stripe Press Collection

4 items
  • The Dream Machine — M. Mitchell Waldrop
    The story of J.C.R. Licklider and the birth of personal computing. Stripe Press at its best: deep history of an idea that changed everything.
  • The Alignment Problem — Brian Christian
    How do we ensure AI systems do what we want them to do? The most thoughtful book on AI safety and ethics I've read.
  • The Roaring Twenties — Benjamin H. Hall
    Economic history of the post-war boom. Relevant to understanding inflation, policy responses, and how economies recover.
  • The Seafaring Tradition — James Nestor
    On how maritime history shapes modern commerce and technology. Unique perspective from Stripe Press.

Ideas That Stuck With Me

7 items
  • Ergodicity
    The insight that time averages and ensemble averages aren't the same thing. Changes everything about how you think about risk and ruin.
  • Mimetic Theory
    René Girard's idea that we desire what others desire. Once you see it, you can't unsee it in markets, politics, and relationships.
  • Skin in the Game
    Taleb's argument that people making decisions should bear the consequences. Fundamental to good regulation and accountability.
  • Second-Order Thinking
    Always ask: and then what? Most policy mistakes and market failures come from ignoring second and third-order effects.
  • The Lindy Effect
    Things that have survived a long time will probably survive longer. A useful filter for what to read, who to learn from, and what to build.
  • Via Negativa
    Improvement by subtraction. Often the best thing to do is remove something rather than add. Applies to policy, code, and life.
  • OODA Loop
    Boyd's observe-orient-decide-act framework. Useful for thinking about organisational speed and competitive advantage.

Interests & Obsessions

6 items
  • Regulatory Economics
    How do you design rules that protect consumers without stifling innovation? This is my day job, essentially. Endlessly fascinating.
  • Iraqi History & Diaspora
    Understanding where I come from. The modern history of Iraq is fascinating and underexplored in English literature.
  • Small Business Finance
    Six years at the British Business Bank showed me how much the SME lending market matters for the real economy and employment.
  • Austrian Economics Tradition
    Studying in Vienna gave me a different perspective. Hayek, Schumpeter, Mises, the whole tradition of thinking about markets and knowledge.
  • Language & Etymology
    Words have histories. Understanding them makes you a better writer, thinker, and communicator. Trilingual perspective helps.
  • Triathlon & Endurance Sport
    The discipline of training for three disciplines teaches you about consistency, marginal gains, and the importance of recovery.

Life Systems

4 items
  • Second Brain (Notion)
    I keep everything in Notion — reading notes, project plans, lists, research. It's how I think externally and maintain context.
  • Spaced Repetition
    Using Anki to remember what I read. Without it, most books would fade in weeks. Spacing out review forces deeper retention.
  • Weekly Review
    Every Sunday: review the week, plan the next one, update the lists. Simple but transformative for clarity and intention.
  • Morning Pages
    Three pages of longhand writing first thing. Clears the mind before the day starts. Unfiltered, stream-of-consciousness thinking.
