The Lighthouse Debate: Samuelson vs. Coase
This is Suzhou Victory Textile Co., Ltd.
There’s a famous debate in economics between two Nobel laureates: Paul Samuelson and Ronald Coase. At its heart—a lighthouse.
1. Samuelson: Lighthouses Are Public Goods—Government Should Provide Them Free
Samuelson argued: A lighthouse stands at sea, its light shining on all. One ship sees it; another sees it too—no interference. That’s a “public good.” One more ship adds zero marginal cost. Charge even a dollar, and some poor skipper might skip it, run aground, sink. So lighthouses must be government‑provided, free of charge, or society loses.
That’s the textbook answer. Samuelson turned economics into a mathematical science; his textbook sold worldwide. Few questioned him.
2. Coase: Wait—Lighthouses Were Private and They Charged
Coase pushed back. In 1974, he published a paper: Samuelson’s lighthouse is blackboard economics. In reality, many early British lighthouses were built by private individuals.
How did they recoup costs? Simple—they collected fees at the dock. Ships dock, someone’s there to collect. The light itself wasn’t charged, but the lighthouse was part of port services. Businessmen aren’t fools; they do the math.
Coase’s lesson: Public goods aren’t necessarily free. Building and maintaining a lighthouse costs money. Even if using it costs nothing, providing it does. Private parties have incentives—if they find the right way to charge.
3. The Hotel Lobby—Free?
Walk into any five‑star hotel: lights, scent, piano, fountain, sofas—all free. One person enjoys them; another does too—classic public goods. Why don’t profit‑hungry hoteliers turn that space into paying rooms?
Because guests need that public space. The room rate already covers it. A free lobby buys higher rates and occupancy.
Beijing’s Indigo mall has a massive public atrium. The designer didn’t fill it with shops; they left it open. Result? Families come, kids play, adults shop—or the reverse. Space is free; traffic pays.
4. Two Reasons to Charge
When governments charge for services, two things happen:
First, demand screening. Roads are private goods—one car occupies, another can’t. Tolls reveal who needs the road most.
Second, economic accounting. Raise bullet‑train speed from 250 to 350 km/h—costs skyrocket. Is saving 15 minutes worth it? Without pricing, you never know. With pricing, you can calculate: Is this investment wise?
5. The Lighthouse Lesson
The Samuelson‑Coase debate teaches us two things:
First, private parties can provide public services. Find the right charging model, and they will.
Second, government charges aren’t evil. They help us make better decisions.
At Suzhou Victory Textile, we make fabrics. Same logic applies. Great fabric feels like lighthouse light—comfortable on you, comfortable on others. But R&D, production, quality control—all cost money. Cost hides in price; price reflects value.
Next time you stay at a hotel, stroll a mall, or scroll your phone, remember the lighthouse. What seems free often costs the most. What carries a price tag may be the best bargain.
灯塔之争：萨缪尔森 vs 科斯
这里是苏州维特瑞纺织。
经济学史上有一场著名论战，主角是两位诺奖得主：保罗·萨缪尔森和罗纳德·科斯。争论的核心，是一座灯塔。
一、萨缪尔森：灯塔是公用品，政府该免费提供
萨缪尔森说：灯塔立在海上，光芒普照。一艘船看见，不影响另一艘也看见——这叫“公用品”。多一艘船使用，边际成本为零。如果收费，哪怕只收一块钱，总有穷船主付不起，他可能因此迷航沉没。所以灯塔必须由政府免费提供，否则会造成巨大的社会福利损失。
这是教科书里的标准答案。萨缪尔森用数学把经济学变成一门科学，他的《经济学》教材卖遍全球。他说的话，没人怀疑。
二、科斯：不对，灯塔是私人建的，还能收费
科斯不干了。1974年，他专门写文章反驳：萨缪尔森讲的，是黑板上的经济学。现实中，英国最早的灯塔，很多是私人建的。
私人建灯塔，怎么收回成本？很简单——在码头收。船停靠码头，就有人等着收钱。灯塔的光不收钱，但灯塔本身就是码头服务的一部分。商人没那么傻，他们会算账。
科斯用这个故事告诉我们：公用品不等于必须免费。修建和维护灯塔，都需要成本。哪怕使用它不花钱，提供它要花钱。私人有积极性干这事——只要找对收费方式。
三、五星级酒店的大堂，免费吗？
你走进任何一家五星级酒店，灯光、香氛、钢琴、喷泉、沙发——全是免费的。一个人享受，不影响别人享受，标准的公用品。商人唯利是图，为什么不把这些空间全改成客房收钱？
因为他知道：客人需要这个公共空间。房费里，早就把这部分成本算进去了。免费的大堂，换来的是更高的房价和入住率。
北京颐堤港购物中心，有个巨大的公共空间。设计师没把它全塞满商铺，反而留出一大片空地。结果呢？大人带孩子来玩，顺便购物；带孩子来购物，顺便玩。空间免费，客流付费。
四、收费的两个作用
政府提供公共服务，如果收费，能干两件事：
第一，筛选需求。道路是私用品——一辆车占了，另一辆就不能占。收费能知道谁更需要这条路。
第二，经济核算。高铁时速从250提到350，成本暴涨。省下那15分钟，到底值多少钱？不收费，永远不知道。收费了，才能算账：这笔投资划算不划算？
五、灯塔的启示
萨缪尔森和科斯之争，给我们两个启发：
第一，私人也能提供公共服务。只要找对收费方式，商人有积极性。
第二，政府收费不是坏事。它能帮我们做对决策。
我们苏州维特瑞纺织，做的是面料，但道理相通。好的面料，像灯塔的光——穿在身上舒服，不影响别人也舒服。但研发、生产、品控，哪一样不要成本？成本藏在价格里，价格背后是价值。
下次你住酒店、逛商场、刷手机，想想灯塔的故事。免费的，往往最贵；收费的，可能最值。
