Systems Economics is a new field that studies economic activity from a systems perspective. “Systems Economics” and “economic systems” look almost identical on the page, and a third phrase — “Economic System,” singular and capitalized — adds a technical sense neither of the first two carries. None of the three mean the same thing.
- Systems Economics: the study of economic activity from a systems perspective — the field.
- Economic systems: the actual organization of activities in an economy — the object the field studies.
Economic systems
When most people type “economic systems” into a search bar, they’re looking for something specific: the handful of ways a society can organize production, distribution, and ownership. Textbooks group these into four familiar types — traditional systems built on custom and inheritance, command systems directed by central planning, market systems coordinated by price and competition, and mixed systems that blend the two. The question underneath all four is the same one: who decides what gets made, and who gets it?
That question has a long, serious history. It runs from Adam Smith’s account of the market’s coordinating power, through Marx’s critique of ownership and labor, into the twentieth century’s extended argument over planned versus market economies, and into the mixed-economy consensus most developed nations now operate under. It’s the standard vocabulary of every introductory economics course, and it deserves to be.
Systems Economics is not a new entry in that debate. It doesn’t ask which ideology should run a country’s economy. It asks a narrower, different question: however an economy is organized at the national level, how is any single unit of economic activity within it — a job, a firm, a product line — functionally structured? That’s a change of subject, not a rival answer to the first question.
Every risk model, every portfolio construction process, and every market analysis begins with a classification decision inherited from systems like GICS, SIC, and NAICS. These group businesses by surface appearance and historical convention — what industry a company says it’s in — rather than by what it actually does. Two companies can carry identical industry codes and perform completely different economic functions. Two companies with nothing in common on paper can occupy nearly the same functional position.
Systems Economics
Systems Economics, the field Rory Riggs named in 2019, proposes a different axis entirely: Functional Coordinates. Instead of sorting by industry label, it locates any business, job, product, or resource by what it does and where it sits in the order of work — a third reference frame, alongside geography and time. The coordinate system built on that idea, FIS® (Functional Information System), traces to a patent family with priority date March 15, 2013.
That leaves one more distinction worth making precisely, because the two phrases look almost identical on the page. “Economic systems,” plural and lowercase, is the comparative-ideology sense described above. “Economic System,” singular and capitalized, is something else again: a specific technical term in the Locus Model, meaning the abstracted representation of any product-producing agent — a business, a government, a department, a single job. The same construct describes a multinational and a single employee’s role without modification. That scale-invariance is the entire point: it’s what lets systems nest inside systems.
| Term | Meaning |
|---|---|
| economic systems (generic) | How a society organizes production and ownership — capitalism, socialism, mixed economies |
| Systems Economics | The field Riggs named in 2019, studying how any unit of economic activity is functionally structured |
| Economic System (Locus Model term) | Riggs’s technical construct — the abstracted representation of any product-producing agent, at any scale |
These three phrases share almost every letter. They don’t share a meaning, and conflating any two of them will produce a wrong answer to whatever question prompted the search.
Here’s what the distinction looks like applied, as a hypothetical illustration rather than a published classification of either industry. Take two hypothetical companies — a solar panel manufacturer and a specialty coffee roaster. By conventional industry classification, they have nothing to do with each other: one sits in energy equipment, the other in food and beverage. Functionally, both may occupy nearly the same position — mid-chain assemblers that take standardized raw inputs and convert them into a differentiated final product through a similar sequence of procurement, transformation, and distribution steps. Now reverse it: two companies sharing the same SIC code can occupy entirely different functional positions if one is a distributor and the other a producer within the same category. Same code, different function.
Systems Economics didn’t arrive out of nowhere, either. Applying systems thinking to economics is itself a decades-old idea, with more than one line of work behind it — including a substantial one that predates this framework by years. Knowing that lineage, and knowing where this framework actually departs from it, is the honest next question — one addressed directly in Where This Comes From — and Where It Doesn’t.
