đ Inflation Fears Rise. Paper Supply Falls.
Building better understanding of global supply chain woes...and subsequent inflation.
Authorâs note (2021)
The following was written prior to news about issues with the transportation system making it harder to get goods across the international economy. These delays only exacerbate the delays in the analysis below, making the impacts of the time delays described here even worse. This is what weâre experiencing.
Authorâs note (2025)
Since this article was written, the world experienced long term inflation â as expected. The US managed to bring inflation under control faster. The analysis still holds regarding structural causes of supply / demand imbalances and inflation.

US News Headline: Delta, Inflation Fears Push Consumer Sentiment Down Sharply in August
If you tune in to the Sunday morning economic pundits youâll hear differing opinions about inflation. Itâs here. Itâs coming. Itâs the current Presidentâs fault. No, itâs the previous Presidentâs. Whatâs going on?
MeanwhileâŚ
A writer friend of mineâexcited to be publishing their third bookâlamented the other day, âI never thought Iâd try to sell a new book in a time when printing paper was hard to find.â Youâd think in a digital age there would be plenty of paper. Why the paper shortage? (Just today, Costco announced a purchase limit for toilet paper similar to 2020âs.)
Perhaps most important of all: How might these seemingly disparate issues be related?
SYSQ CAN ILLUMINATE
Systemic Intelligence (SysQTM) is the capacity to frame and analyze issues in ways that can generate maximum insightâwhich is the only way to identify optimal solutions. One of the core principles of SysQ is to Build a Shared Map of the territory of interestâa picture of the systemic structure driving the systemâs performance. Another principle is to Focus on the Physicsâmake sure the mapâs proposed causal connections are consistent with reality.

THE BASICS OF SUPPLY AND PRODUCTION

A 30,000 meter view of any industry might look like the map above. At any point in time, you can count up the current amount of goods in the Goods Inventory stock. The stock is like a bathtub. It accumulates inventory.
What fills it up each week is the amount of producing (production) that week. This inflow of producing is like the spigot into a bathtub. The valve (on top) determines how fast or slow the bathtub of Goods Inventory fills. On the outflow, Consumer Demand determines how much selling (inventory sold per week) occurs weekly. If Demand increases, the rate of selling goes up. Lower Demand reduces the rate of selling.
Bathtub physics dictate that Goods Inventory goes up anytime the rate of producing exceeds the rate of selling. The only time Goods Inventory decreases is when selling exceeds producing.
The B1 indicates a balancing loop. Balancing Loops try to maintain equilibrium. If Goods Inventory declines, Price rises, utilization increases, Goods Inventory bounces backâŚand Price decreases again.
INCREASING THE CAPITAL STOCK INCREASES PRODUCTION
Producing occurs from applying Production Capital. Production Capital is also a stock, because you can stop time and in that moment count up the total amount of capital available. The rate of producing (units of goods produced / week) is determined by Production Capital * utilization (units of goods produced / unit of capital / week). To produce more requires increasing either the amount of Production Capital or its utilization (productivity) of capitalâor both.
The binary shading of the producing flow indicates that thereâs not a 1:1 conversion of raw material units into units of goods. One computer (a good) requires thousands of parts (raw materials like chips, boards, wires, etcâŚ).
When Goods Inventory is running low, and especially when Price is high and industry profitable, organizations will order more raw materials, increase utilization and/or invest in new capital.

NOTE: Itâs often easierâand takes significantly less timeâto increase productivity (aka utilization) than to add Production Capital. Adding capital usually requires a flow (activity) of investment in production capital. That capital then steps onto a development conveyor and doesnât actually become available to produce for a while. Sometimes this time delay takes months.
SUPPLY RELATIVE TO DEMANDâ>PRICE
If Demand increases, the rate of selling increases, drawing down Goods Inventory. The Supply relative to Demand falls; Price will increase.

A producer typically responds by increasing utilization (units of goods produced per unit of capital) in order to produce more, filling up Goods Inventory, and bringing supply and demand back into balance. Price usually stabilizes to previous levels. Sometimes, producers will invest in new capital to increase production. This requires a much longer time horizon in order to implement.
**WHY INFLATION? WHY SUPPLY SHORTAGES? AT THE SAME TIME?**
Under most situations, these balancing loops work to regulate the market so that production, inventories, and price oscillates around equilibriumsâoften with a little annual growth to create an upward sloping curve.
A Sustained Shock
But what happens occasionally are sustained shocks to a system. For example, if thereâs a broad and sustained shock to demand (e.g. a lockdown), the following might occur.

Demand (blue trend) plummets and stays low. Supply relative to Demand begins to creep up (as unsold inventories increase). Too much supply causes Price to drop (or at least not increase anymore).
All of these reduce short-term utilization and materials ordering. This means less harvesting of trees, less of simple materials that are components to chips and computers, less of the basics. There will be less Raw Material Inventory (orange trend)
Further, Production Capital naturally retires, so the stock diminishes (or certainly doesnât grow).
Demand Returns, But System Remains Behind
If Demand suddenly returns, the system canât adjust back to normal immediately. Because Goods Inventory is now insufficient for this increased Demand, Supply relative to Demand decreases, and Price increases.

Utilization, ordering, and investing in production capital increases. But due to the long time delaysâsome delays are substantialâPrice continues to rise as Supply relative to Demand remains low.
And INFLATION!
Inflation Continues
Inflation (increasing Price above wage increases) will continue for a long time as the system tries to recoverâŚespecially if Demand continues to remain high. The long pipeline delays ensure this dampening of inflation takes time.
Solutions?
What will address this shortage combined with inflation? The main national lever works on demand. The strongest lever is the natural one: Priceâ>Demand. Yes. Prices will eventually go high enough to naturally suppress demand. As selling slows, inventories can catch up, and Price will fall (or stop rising as fast).
Policies that could slow demand sooner might include short term taxes on some (perhaps luxury) items that require a lot of raw materials. This would increase actual Price faster than inflation and put the brakes faster. Plus, luxury items taxes wouldnât negatively impact those suffering the most. And if the tax was reinvented in ways that increase the development of supporting infrastructure and capital, then the system would rebound faster.

Additionally, there could be incentives to industries to invest in capital even when their forecasts donât encourage them to do so. Incentives to add supporting infrastructure or invest in employee development would pay off in the medium to short term.

IMPLICATIONS
What happened in 2020 was unique in that Demand was suppressed suddenly (lockdowns) and for a longer time than typically. This means that rising inflation now is absolutely to be expected. So, whoâs to blame?
The current President wasnât responsible for the 2020 sudden and sustained decrease in Demand. And the previous President, although a different way of handling the pandemic might have reduced the impact on Demand, isnât responsible for the way the market is now responding to reinvestment to bring production back up to previous levels.
Key Insight
Todayâs macroeconomic performance is rarely the result of decisions made within the past few months. Using a longer term mental model of the structure generating performance will increase our ability to assess any attributions of âwhoâs to blame?â
