monopsony
Monopsony is a market with only one major buyer, so that buyer can dictate low prices or low wages because sellers have nowhere else to go.
In plain English
Every graduate in a small Nigerian town knows this feeling. There is one big company in town, maybe the only bank branch hiring, the only factory, the only telecoms office, and if you want a job that pays anything close to decent, you go there or you leave town. That company does not need to be generous with salaries because it knows you have no other door to knock on.
That is monopsony. We usually talk about monopoly, one seller controlling a market and squeezing buyers. Monopsony flips it. One buyer controls a market and squeezes sellers. The sellers here could be workers selling their labour, or farmers selling their cocoa, or small suppliers selling their goods to one giant retailer.
Think of cocoa farmers in a rural part of the southwest who can only sell to one licensed buying agent in their area. That agent sets the price low because the farmers cannot easily transport their harvest elsewhere before it spoils. The farmers work just as hard, but the price they get depends entirely on the mood of one buyer.
In the United Kingdom, this shows up when a single large supermarket chain becomes the main buyer for local dairy farmers. The farmers keep producing milk, but the price offered can sit painfully close to the cost of production, because switching buyers is not simple.
There is a diaspora version too. Someone in Lagos doing remote work for one foreign client, and only that one client, can find themselves calmly accepting lower pay than the work deserves, because losing that single client feels like losing everything.
Monopsony explains why some hardworking people and honest producers never seem to get ahead. It is not laziness. It is the shape of the market they are trapped inside.
A poultry farmer in Ogun State supplies eggs to the only large hotel chain buying in bulk in the area. The hotel offers ₦1,200 per crate, well below what farmers in a more open market get, but with no second buyer nearby, the farmer accepts it to avoid wasted stock.
Questions people ask
Is monopsony the same as monopoly?
No. Monopoly is one seller controlling prices for many buyers. Monopsony is the mirror image, one buyer controlling prices for many sellers, whether those sellers are workers, farmers, or small suppliers.
Can monopsony happen in labour markets specifically?
Yes, and this is one of its most common forms. If one employer dominates hiring in a town or a specialised industry, workers have little room to negotiate wages, since leaving means leaving the only real job option.
How do sellers protect themselves from monopsony power?
Usually through collective action, such as farmer cooperatives negotiating together, trade unions bargaining for workers, or government intervention through minimum price guarantees, since a single seller alone rarely has enough leverage to change the buyer's terms.
