For several decades, goods made in China have carried a reputation for low prices and uneven quality. That reputation did not appear from nowhere, and it is more useful to explain it than to dispute it. This article looks at the economics behind it: where a low price comes from, why price and quality stay linked over time, and why Smile Lighting does not offer to win an order by quoting the lowest number.

A Reputation Is an Equilibrium, Not a Trait

In any market where buyers cannot easily judge quality before they buy, price becomes the main thing they can compare. George Akerlof described the consequence in his 1970 paper on the market for "lemons": when quality is hard to observe, a supplier who cuts quality can undercut one who does not, and over time the prevailing price drifts toward what only the lowest-quality suppliers can sustain. Suppliers who keep higher standards are squeezed out, or are pushed to lower them.

This is a property of market structure rather than of any nation. Britain introduced the "Made in Germany" mark in 1887 partly to flag imported goods it regarded as inferior, and similar reputations attached to other industrializing economies during their own periods of rapid export growth. A reputation of this kind describes the incentives a market created, and it changes when those incentives change.

Where a Low Quote Comes From

A manufacturing price is the sum of materials, labor, process control (inspection and testing), overhead, and margin. A lower quote means one or more of those has been reduced, so the useful question is how. Some reductions come from productivity: the same output from fewer resources. Others come from compression: the same price tag over a thinner product or process. The two can look identical on a quotation sheet, and they have opposite consequences.

Source of Lower CostTypeEffect on Quality Over Time
Larger volume and purchasing scaleProductivityNeutral: fixed costs are spread over more units
Automation, tooling, design for manufactureProductivityNeutral to positive: consistency usually improves
Higher first-pass yield, less scrapProductivityPositive: fewer defects to catch or hide
Lower-grade material or component substitutionCompressionNegative: failures appear after installation
Reduced testing and inspectionCompressionNegative: defects pass through to the buyer
Labor cost pushed below a sustainable levelCompressionNegative: turnover, disengagement, skipped steps

How Cost Compression Feeds Back Into the Market

Compression does not stay contained within one supplier. Once a below-cost price is accepted in a market, it becomes the reference point, and suppliers who want the same orders face the same pressure.

Lowest-price commitment Cost compression Weaker checks, higher turnover More defects and returns Price becomes the only signal Feedback: the next round of price competition starts from a lower reference point

A price-only market tends to reinforce itself, because each round of compression lowers the reference price for the next.

The Labor-Cost Mechanism

Labor is a large share of cost in most manufacturing, which is why it is often the first line to be compressed. It is also the channel through which every quality system operates. Procedures, performance indicators, inspection checkpoints, and housekeeping standards such as 5S are written by managers but carried out by the people on the line. Their reliability depends on whether those people have reason to follow them.

Efficiency-wage theory, formalized by Carl Shapiro and Joseph Stiglitz in 1984, describes the logic. Where monitoring is imperfect, a wage that barely covers subsistence gives a worker little to lose from cutting a corner, and supervision cannot fully make up the difference. Paying enough that the job is worth keeping is a cost, but it also lowers turnover, preserves trained skill, and reduces the amount of supervision required.

Early assembly-line history offers a concrete case. In 1913, Ford Motor Company hired roughly 50,000 people to maintain an average workforce of about 13,600, a turnover rate of about 370 percent. In January 1914 it announced a five-dollar, eight-hour day, which came with eligibility conditions. Turnover is reported to have fallen to about 54 percent in 1914 and 16 percent in 1915 (Raff and Summers, 1987). Ford's motives are debated, but the episode illustrates a general point: the wage was part of the production system, not only an expense attached to it.

Why the Difference Is Invisible at the Point of Sale

At purchase, a buyer sees the unit price. The cost of a failure arrives later: replacement units, shipping, installation labor, access to the fixture location, project delay, and customer support. For lighting this matters more than it might for other goods, because fixtures are often installed in places that are costly to reach, and the labor to replace one can exceed the fixture's price.

ItemQuote AQuote B
Unit price$10.00$8.50
Assumed failure rate1%6%
Cost per failed unit (replacement, installation labor, shipping, support)$60$60
Effective cost per unit (price + failure rate × cost per failure)$10.60$12.10

Hypothetical figures, used only to show the structure of the calculation.

The break-even is simple. The cheaper quote remains cheaper only if its additional failure rate stays below the price gap divided by the cost per failure: here $1.50 ÷ $60, or 2.5 percentage points. The figures above are invented, but the structure applies to any real comparison, and the cost per failure usually turns out to be larger than buyers assume at the time of ordering.

Our Position

Smile Lighting has manufactured lighting fixtures for more than twenty years, and we have watched this dynamic from the production side. Our conclusion is a plain one: we do not offer to undercut a competitor's price in order to win an order. We quote the cost of making a fixture to its specification, which means materials of the stated grade, the testing the product needs, and a workforce that is trained and retained, and we try to be explicit about what each part of a quote covers. When a requested price falls below that cost, the honest options are to change the specification or to decline, not to change quietly what is delivered.

There is also a game-theoretic reason. A single transaction rewards a supplier who cuts corners and a buyer who squeezes. A repeated relationship rewards both for dealing straightforwardly, because each expects to deal with the other again. In OEM and ODM work the logic is sharper still, since the buyer's own name is on the product. We would rather build the second kind of relationship, in which both sides gain over repeated orders.

A Limit of This Argument

None of this means a lower price always signals lower quality. Scale, automation, better tooling, shorter supply chains, and process improvement all reduce cost without reducing quality, and a supplier who has achieved them can legitimately quote lower. The claim here is narrower: a price far below what the specified materials, testing, and labor would cost needs an explanation, and the explanation matters more than the number.

Questions Worth Asking About Any Quote

Productivity-Based Savings

Can be explained in terms of volume, tooling, yield, or process, and usually survive a request to document them.

Compression-Based Savings

Tend to be hard to explain without referring to a change in material, testing, or conditions that the quote does not mention.

  1. What grade or specification applies to each major material and component, and is it written into the quotation rather than left implied?
  2. What testing and inspection are included, at which stages of production, and who carries them out?
  3. How long does the production team typically stay, and how is new staff trained before handling finished product?
  4. What happens when a unit fails, and who bears the cost of replacement and installation labor?
  5. If the price is lowered on request, which specific element of the quote changed?
Practical Note

A quote that drops sharply on request, with no change to the specification, carries information: either the original contained slack, or the revised version has removed something. Asking what changed is a reasonable way to find out which.

Common Oversight

Comparing unit prices alone treats quotes as though they describe identical goods and identical risk. When specification, testing, and failure handling differ, the unit price is only one component of the real cost.

Price as Information

A price is a figure, and it is also a signal about how a product was made and what happens if it fails. Reading it that way does not require distrusting every low quote. It requires asking where the savings came from, because over a long enough period the answer shows up in the product, in the buyer's total cost, and in the reputation of the market as a whole.
