A video lesson on deflation and Japan’s lost decades
The deflation concept in the Money and Banking atlas now opens with a short animated video lesson that walks through the deflationary spiral, debt-deflation, the zero-lower-bound trap, and Japan as the real-world case.
- AddedA short animated video lesson on deflation, embedded on the Money and Banking concept page and listed on the Lessons page.
v1.27.2Jun 5, 2026
A new concept on deflation and Japan’s lost decades
The Money and Banking atlas gains a concept on deflation and persistently low inflation, anchored to Japan’s experience since the late 1990s. It explains the deflationary spiral, Irving Fisher’s debt-deflation, and why a falling price level is so dangerous once interest rates are near zero, which is why central banks aim for a small positive inflation rate rather than zero.
- AddedA Money and Banking concept on deflation, debt-deflation, and the zero lower bound, with Japan’s lost decades as the real-world case.
v1.27.1Jun 5, 2026
Accessibility, mobile, and search polish
A polish pass across the four atlases. Labels that read gold on a white card now use a darker, easier-to-read gold that meets accessibility contrast. The concept map and the widgets sit better on phones and tablets, with larger tap targets and a graph that no longer hides under the mobile browser bar. Search now tells you when nothing matches, and all four course atlases are searchable, not just Derivatives.
- ImprovedGold labels on white now meet WCAG AA contrast, tap targets are larger, and the concept map and widgets fit phones and tablets better.
- ImprovedSearch shows a clear no-results message and is now available on all four course atlases, not only Derivatives.
v1.27.0Jun 5, 2026
A model-specification sandbox, swap comparative advantage, and three more real cases
Econometrics gains a specification sandbox that shows, on one scatter, how functional form (logs and elasticities), a squared term, and dummy variables each change what a coefficient means. Derivatives gains a comparative-advantage swap allocator that splits the quality-spread differential between two firms and a dealer. Money and Banking links its open-market-operations page to the reserves-market tool. Three more concepts are anchored to verified events: the Terra and Luna stablecoin collapse of 2022, the Asian financial crisis of 1997, and the GameStop short squeeze of 2021.
- AddedAn Econometrics specification sandbox (functional form, polynomials and interactions, dummy variables) and a Derivatives comparative-advantage swap allocator.
- AddedVerified real-world cases woven into Money and Banking: Terra and Luna 2022, the Asian financial crisis 1997, and the GameStop short squeeze 2021.
- ImprovedThe open-market-operations page now opens the interactive reserves-market tool.
v1.26.0Jun 5, 2026

Every course gains hands-on widgets. Econometrics gets a Monte-Carlo sampling-distribution simulator and a t-test and confidence-interval explorer. Money and Banking gets a bank-run and deposit-insurance simulator. Derivatives gets counterparty exposure, futures-to-spot convergence, and a rate-futures profit-and-loss explorer. Investment Management gets a Sharpe, Treynor and Jensen performance dashboard. Several concepts are now anchored to verified real events: Silicon Valley Bank in 2023, the State Bank of Vietnam managed float, Lehman Brothers in 2008, the Volcker disinflation, and the Granger and Newbold spurious-regression study.
- AddedSeven new interactive widgets across Econometrics, Money and Banking, Derivatives, and Investment Management, from a sampling-distribution simulator to a bank-run model and a fund performance dashboard.

- ImprovedMore concepts across the four atlases now open an interactive tool.
v1.25.0Jun 5, 2026
New interactive tools and a smoother atlas
Three new interactive widgets join the Derivatives atlas: an American early-exercise tree that shows when exercising early beats holding, a daily mark-to-market ledger that fires margin calls along a price path, and a Greeks dashboard for all five sensitivities. The atlas itself is friendlier too — a first-visit guide, a visible "explored" progress counter, and a direct link from every video lesson into the matching concept.
- AddedThree new interactive Derivatives widgets: American early-exercise, a daily mark-to-market ledger with margin calls, and a Black-Scholes Greeks dashboard.
- AddedA first-visit guide to the concept map, a visible progress counter for concepts you have explored, and a link from each video lesson straight to its concept in the atlas.
- ImprovedThe atlas concept map is now fully keyboard-navigable and respects the system reduce-motion setting, and pages load lighter across the site.
v1.24.0Jun 3, 2026
Common Threads: how the courses connect
A new page draws the four course atlases as one picture and shows the concepts they share. Present value, bond pricing, duration, risk and return, market efficiency, stock valuation, behavioural finance, and regression all recur across courses, and Common Threads lets you hover any one to see where it appears and follow it into each atlas. It is the connective tissue between Derivatives, Money & Banking, Econometrics, and Investment Management.
- AddedA new "Common Threads" page that maps the four course atlases and the shared concepts that connect them, with a link from each concept into every course that teaches it.
v1.23.0Jun 3, 2026
More hands-on Money & Banking tools
Four more interactive tools join the Money & Banking atlas. You can run the quantity theory of money and watch inflation track money growth net of real output, work the Fisher equation to see how an inflation surprise erodes the real return on a nominal loan, explore the market for reserves to see how a central bank’s floor system pins the policy rate, and test purchasing power parity to read the exchange rate implied by two price levels and spot an over or under-valued currency.
- AddedFour interactive tools on the Money & Banking atlas: a quantity-theory-of-money explorer, a Fisher-equation tool separating expected from realized inflation, a market-for-reserves diagram showing how the policy rate is set, and a purchasing-power-parity exchange-rate tool.
v1.22.0Jun 3, 2026
The Investment Management Atlas becomes hands-on
Interactive tools now sit on the Investment Management atlas. You can drag the two-asset efficient frontier and watch a lower correlation bow it toward the axis, switch it to show the capital allocation line and the Sharpe-maximising tangency portfolio, slide a beta along the Security Market Line to read the CAPM-required return and spot under or over-valued stocks, value a share with the Gordon growth model and watch the price explode as growth approaches the required return, and model how a startup founder is diluted across funding rounds. The bond price-and-yield and duration-and-convexity tools carry over to the fixed-income concepts too.
- AddedInteractive tools on twelve Investment Management concepts: an efficient-frontier and capital-allocation-line explorer, a CAPM and Security Market Line tool, a Gordon-growth dividend-discount valuer, a startup pre-money, post-money and dilution model, and the bond price-yield and duration-convexity tools reused on the fixed-income concepts.
v1.21.0Jun 3, 2026
A fourth atlas: Investment Management
The site now hosts a fourth interactive atlas, for Investment Management, anchored on Brailsford, Heaney and Bilson. It opens with 57 concepts across eight themes: the investment environment, fixed income, market efficiency, fundamental analysis, technical and quantitative analysis, portfolio optimization and asset pricing, startup fundraising, and ethics. It follows the working analyst from sizing up a market and an asset class, through valuing a company and building an optimized portfolio, to raising capital for a venture and the ethics that bind the profession.
- AddedAn Investment Management Atlas of 57 connected concepts across eight themes, from the CAPM, the efficient frontier, and fundamental valuation to bond duration, behavioural finance, venture-capital fundraising, and the CFA Institute Standards, each with the intuition, key formulas, a worked example, common misconceptions, a quiz, and academic citations.

v1.20.0Jun 3, 2026
The Econometrics Atlas becomes hands-on
Five interactive tools now sit on the Econometrics Atlas, one on each core idea. You can drag a regression line and watch the sum of squared residuals refuse to beat the least-squares fit, dial up omitted-variable bias and see the short regression drift away from the truth, compare classical and heteroskedasticity-robust standard errors on the same estimate, slide an AR(1) coefficient from mean reversion through a random walk to an explosive path, and turn up the correlation between two regressors to watch the variance inflation factor blow up. Each tool lives on its concept page and in the atlas detail panel.
- AddedInteractive tools on nine econometrics concepts: an OLS line-and-residuals explorer (with the R² decomposition), an omitted-variable-bias simulator, a classical-versus-robust standard-error comparison, a random-walk versus AR(1) unit-root explorer, and a multicollinearity and variance-inflation-factor tool.
v1.19.0Jun 3, 2026
A third atlas: Econometrics
The site now hosts a third interactive atlas, for Economic and Financial Modelling, anchored on Wooldridge. It opens with 49 concepts across six themes: foundations and data, simple regression, multiple regression and inference, specification and data problems, heteroskedasticity, and time series. Each concept carries the intuition, the key formulas, a worked example in Stata, the common misconceptions, a quick quiz, and academic citations, and the spine of the atlas follows the working econometrician from assumption to violation to test to remedy.
- AddedAn Econometrics Atlas of 49 connected concepts across six themes, from the Gauss-Markov assumptions and omitted-variable bias to heteroskedasticity-robust inference, unit roots, and cointegration, each with the intuition, key formulas, a worked Stata example, common misconceptions, a quiz, and academic citations.
- AddedThe course switcher now spans three atlases, Derivatives, Money & Banking, and Econometrics, all featured on the home page.

Real-world case studies
The Money & Banking atlas now carries eight integrative case studies that tie the concepts together around real events: the 2008 Global Financial Crisis, the Volcker disinflation, the Great Inflation of the 1970s, the 1997 Asian financial crisis, the GameStop short squeeze, the Terra-Luna stablecoin collapse, the March 2020 dash for cash, and how Vietnam navigates the exchange-rate trilemma. Each case links the concept nodes it draws on, so you can watch the theory play out in history.
- AddedEight case-study nodes in the Money & Banking atlas, each synthesising several concepts around one real event, from the 2008 crisis and the Volcker disinflation to the GameStop squeeze, the Terra-Luna collapse, and Vietnam and the trilemma.
v1.17.0Jun 2, 2026
A second atlas: Money & Banking
The site now hosts a second interactive atlas, for Money, Banking and Financial Markets, anchored on Mishkin. It opened with 31 concepts and has grown to 53 across six themes: interest rates and the term structure, central banking and monetary policy, the stock market and efficiency, money, crypto and CBDCs, banking and financial regulation, and international finance. Hands-on tools sit on the core concepts, and a switcher in the header moves between the two atlases.

v1.13.0Jun 1, 2026
The Atlas becomes hands-on
Interactive tools grew from a single calculator to tools on 65 derivatives concepts. You can shape an option’s Greeks, draw a payoff at expiry, price an option with Black-Scholes or a binomial tree, build the fair futures price from the cost of carry, size a hedge, value an interest-rate swap, read a forward rate off the yield curve, and watch a bond’s price move with its yield through duration and convexity. Each tool lives on its concept page and in the Atlas detail panel, and follows you onto related concepts.
- AddedInteractive tools on 65 concepts: margin calls, an option-strategy builder, a Black-Scholes pricer, a binomial tree, cost-of-carry futures, bond price-and-yield, option Greeks, payoff diagrams, hedge sizing, swap valuation, forward rates, and duration and convexity.
- AddedTwo new concepts, Duration and Convexity, each with its own bond-risk tool that shows the convexity correction to the straight-line duration estimate.
- ImprovedThe pricing tools follow you onto related concepts, so the right one tends to be waiting wherever you land.
v1.9.0May 31, 2026
The site goes bilingual
The home page and the full academic profile gained an English and Vietnamese toggle, remembered between visits. The Vietnamese version is a natural rewrite for Vietnamese students and visitors, not a machine translation, while course names, journals, and the atlases themselves stay in English. Vietnamese accents render as clean single glyphs everywhere, and every font now loads from the site itself for a faster first paint.
- AddedAn English and Vietnamese toggle on the home page and the academic profile, with the choice remembered on your next visit.
- ImprovedCrisp Vietnamese diacritics across the site, with the page fonts self-hosted for faster loading and no third-party request.
