Uses and Misuses of Price's Law or Pareto Principle

The notion that a five percent to 10 percent reduction in force at a large organization might be "productivity-neutral" or even "productivity-positive" rests on the premise that large organizations eventually suffer from organizational entropy or “slack.”

In massive corporations, the individual contribution of an individual is notoriously difficult to measure, if it can be measured at all.

The Pareto Principle (80/20 rule) suggests that 80 percent of the value is produced by 20 percent of the employees. If this holds true, a 10-percent layoff that misses the "vital 20 percent" would, mathematically, have a negligible impact on total output.

Price's Law likewise suggests that half of organizational output is created by just 10 percent of workers.

But the idea can be carried too far. In other words, Pareto might suggest  where value is concentrated, but it does not tell us what parts of the value chain, in what quantities, we can try to remove.

In other words, complex products often require many value chain contributions whose contributions are outside the “80 percent of value” attribution, but are still essential for product success. 

The logic of eliminating most of the other value chain elements outside the “80 percent of value” only works only when inputs are independent and optional. That is rarely, if ever, the case for most products. 

For example, a particular  product ships only if every step is completed. So even low-value steps are non-optional constraints. 

Also, some value chain operations represent option value or risk reduction. They might not show up in the completed product, but might instead provide protection against product failure. 

Quality assurance efforts, regulatory compliance or maintenance might not be direct value creators, but might be necessary to deliver a final product. 

So many functions might be structurally necessary but individually have low marginal impact. And even that does not help address the question of staffing levels to support such processes. 

Were that not the case, competitive markets would force firms toward the Pareto-suggestion of minimal staffing. And we do not see that.

That noted, Pareto does make sense for:

• Prioritizing improvements (fix top 20 percent of defects)

• Sales focus (top 20 percent of customers or products)

• Time allocation (focus on high-leverage activities)

Still, Pareto notwithstanding, large organizations might often be less productive than imagined because of:

• Social Loafing: In large groups, individuals often work less hard than they would alone because their lack of effort is easily hidden by the group's overall performance

• Bureaucratic Friction: Beyond a certain size, organizations require "coordinators for the coordinators." Removing a layer of these roles can actually speed up decision-making, allowing the remaining staff to be more productive because they spend less time in meetings.

So when an organization has excess personnel, it can often absorb a reduction in force without losing core output, effectively "trimming the fat" to improve the output-per-employee ratio.

The caveats are several.

Guthrie and Datta warn that in organizations with high innovation requirements, a 10-percent cut can remove critical "intangible assets" whose loss will not be seen until later. 

The Cascio study suggests that many firms fail to see long-term productivity growth after layoffs because they lose the ability to innovate

In other words, if the ideal is “cutting fat but not muscle,” the danger is “cutting some muscle as well.”.

If “productivity” is defined as total output divided by total input, then a smaller denominator “automatically” raises productivity, assuming output remains the same. 

The argument is that many large firms have enough "operational slack" (excess resources) that a five-percent to 10-percent  cut acts as a "forcing function," requiring the remaining staff to automate or abandon low-value tasks.

Large organizations are complex, so it might not be easy to determine how much, and where, to make layoffs. If one assumes every existing function actually is essential, then an “across the board” approach actually makes some sense.

The organization keeps the function, but possibly operates more efficiently. 

Price's Law: 10% of People Produce 50% of Outcomes

Price's Law states that half of the literature on a subject will be contributed by the square root of the total number of authors publishing in that area.

Extrapolated to organizational output, Price’s Law suggests 10 percent of people produce half the outcomes, while 90 percent produce the other half. 

In principle, it is similar to the Pareto theorem, which states that 80 percent of outcomes are produced by 20 percent of the actions.

And remember it is a square root or power law function: the disparities grow larger with scale. The percentage of people producing half the value actually decreases with scale. The Pareto theorem, for example, is linear. It suggests 20 percent of actions produce 80 percent of value, at any scale.

Price’s Law is different. As population size grows, though the number of those contributing half the value grows, they grow at ever-decreasing rates in relation to the total number of associates.

That is one reason why very-large organizations contain so many people who are apparently not functioning at a high level. 

A "Lazy" AI Narrative, Indeed

With the caveat that the statement is in accordance with his firm’s core business value, Jensen Huang is right when he says blaming artificial intelligence for mass layoffs is a “lazy narrative” used by executives to reframe older business problems.

Instead, such layoffs are about redeploying assets. Granted, the redeployment is to support spending on AI infrastructure. 

But the moves are about capital allocation, not AI job replacement; not yet. Overhiring during the Covid pandemic is more accurately the case, as firms now are rebalancing workforces that had become “bloated.”

Consider Price’s Law. 

You might not believe there is a logic to applying Price’s Law to significant large-organization layoffs, but there is a clear rationale. 

Price’s Law suggests that in any complex social system, achieving equality of outcome and equality of opportunity simultaneously is fundamentally impossible.

Applied to work groups and teams, Price’s Law suggests that the square root of the number of people in a domain creates 50 percent of the value:

• In a company with 100 employees, 10 people produce half the output

• In a field with 10,000 scientists, 100 produce half the meaningful research

• On a team of 25, 5 people carry the entire operation.

At least in principle, in a sufficiently-large entity, reducing headcount by 10 percent might not reduce total output much, if at all. 

Price’s Law is like the Pareto Principle (“80/20 rule”): a relatively small number of actors or actions produces a disproportionate percent of total value in any company, process or value chain. 

examples of Price’s law:

• Wealth distribution: The “Global Wealth Report” by Credit Suisse says 1.1 percent of the world’s population (56 million people) holds about 46 percent of the world’s total wealth

• Savings: A small number of people will have 50 percent or more of the total savings in a society, while most people will have very little — if any — savings

• World news: A fraction of world events makes up the vast majority of the news reported on in the media

• Number of books sold: A few authors will sell the vast majority of copies (Stephen King, J. K. Rowling, etc.). This can also be seen with music records, movie scripts, paintings, or any other creative product

• Classical music: Supposedly, 50 percent of the repertoire of classical music was composed by five composers — Bach, Mozart, Beethoven, Brahms, and Tchaikovsky

• Sports: Most tackles in a football game are executed by the same few defensive players. Likewise, most field goals in a basketball game are scored by the same few offensive players. Same in hockey, soccer, other sports

• A few metropolises are home to the majority of humans, while a plethora of smaller cities and villages house the rest

• About 65 percent of all businesses don’t make it past the ten-year mark, creating relatively little revenue. Of the remaining 35 percent, only a fraction creates most of the total revenue

• Web traffic: It is estimated that 90 percent of all websites don’t receive any organic traffic, while the remaining 10 percent get it all.

But there are differences.

Pareto distributions are usually observed in large-scale phenomena such as  crop yields, investments or software problems. 

Price’s law focuses on social group settings. And, unfortunately, the bigger the group, the more incompetence is found.

The Pareto Principle outcomes tend to scale linearly; Price’s Law outcomes scale exponentially. 

But keep in mind that Price’s Law refers only to quantitative outcomes, and does not address qualitative impact.

One scientist might publish 10 papers in one year, but with very little impact on the field, while another scientist might publish just one paper in 10 years and completely revolutionize the field.

The point is that AI is not yet “taking jobs.” 

Firms are shifting resource allocations to support AI infrastructure, yes. Yet even so, Price’s Law suggests that a thoughtful rebalancing might not affect firm productivity.

Which Future for Neoclouds: Rational Consolidation or Collapse?

Technology market structures tend to change as they age. Small upstart companies get acquired; bigger firms merge; a few dominant leaders emerge, taking a “winner takes most” structure. 

Any market researcher, studying any particular capital-intensive market, will tend to find something like a Pareto distribution often applies: up to 80 percent of results are produced by 20 percent of actors. Some might call that the rule of three. 

Market share structures in computing, connectivity and software tend to be fairly similar: leadership by three firms, corresponding to the rule of three. 

“A stable competitive market never has more than three significant competitors, the largest of which has no more than four times the market share of the smallest,” BCG founder Bruce Henderson said in 1976.  

Codified as the rule of three, the observations explains the stable competitive market structure that develops over time, in many industries. 

Others might call this winner take all economics. 

So a logical question is what happens in the high-performance computing market, including the market space for neocloud providers such as CoreWeave, Nebius and others changing their business models from bitcoin mining to focus on artificial intelligence model training and inference operations. 

Some might argue we are shifting from a focus on training capabilities and towards inference operations. It’s hard to argue with that observation, as models become routine apps used by businesses and consumers. 

So some might argue we could see less need for highest-performance compute capabilities of the sort neocloud providers offer. Others might argue more of the computational load will be handled by edge devices, and there is some truth to that position as well. 

But inference operation ubiquity does not necessarily mean less power; less powerful chips; fewer operations inside massive data center complexes; less physical real estate or water consumption. 

Although pre-training growth is slowing, and compute is shifting from training to inference, the compute demands from post-training scaling and test-time scaling, and increased usage suggest that the world likely needs a lot more AI-focused data centers, and the ramp from US$300 billion to US$400 billion in 2025 to roughly US$1 trillion in 2028 is directionally realistic, according to one Deloitte estimate. 

So the future might not include less need for high-performance computing facilities. 

On the other hand, what technology market has not evolved over time to patterns with just a handful of market leaders?

So if the independent neocloud provider market follows the historic pattern, market consolidation will happen, with a handful of major, scaled neocloud providers; traditional hyperscalers, plus a long tail of smaller, niche players.

Some argue the process has already begun. 

But there are other possibilities as well.  The neocloud provider market might not consolidate but instead collapse.

The "Big Three" hyperscalers possess massive scale, deep financial resources, and comprehensive service portfolios, allowing them to engage in price wars and continuously innovate at a pace the smaller players cannot match. So some would argue this creates immense and unsustainable pressure on the neoclouds' margins and ability to compete effectively in the long term.

Without a genuinely-unique value proposition or niche, the independent neocloud providers might struggle to retain customers who often prefer the security and breadth of services offered by the large providers.

The hyperscalers also will be better positioned to handle the likely higher regulatory costs, ability to attract talent and risk aversion of enterprise customers, as well. 

A collapse scenario might happen for at least some providers if customers abandon the neoclouds because of longevity fears. The danger cannot be dismissed. 

That happened around the turn of the century to many would-be capacity providers and competitive local exchange carriers. 

In the late 1990s, driven by the Telecommunications Act of 1996, which opened markets to competition, hundreds of new companies rushed to build wide-area optical fiber networks and local access facilities.  

This resulted in a vast oversupply of "dark fiber" (unused capacity), with estimates suggesting 85 percent to 95 percent of constructed fiber went unused after the bust. 

The industry and investors widely believed demand for bandwidth would grow indefinitely, leading to an investment frenzy based on the mentality of "if you build it, they will come". Actual demand and revenue growth, however, did not keep pace with the rapid network construction, creating an unsustainable business model for many.

CLECs and fiber providers were able to secure massive amounts of funding through debt and speculative equity offerings. When the broader stock market began to decline in 2000, this financing dried up, immediately pushing heavily leveraged companies into bankruptcy.

Hypercompetition and Price Wars: The presence of too many competitors in the same markets led to vicious price wars that drove down bandwidth prices (in some cases, by 60 percent per year), making it difficult for many new entrants to become profitable or even cover their costs.

In that case, rational merger activity did not drive the consolidation. Instead, the sectors mostly collapsed into bankruptcy. It’s impossible to tell, today, which of these outcomes develops. Over-investment, over-capacity and inadequate demand have happened with many earlier technologies, including railroads in the nineteenth century; the telecom and internet bubbles of the late 1990s and early 2000 era.
