You may notice that the same thing does not always cost the same amount. An airline ticket may become more expensive as the travel date approaches, a hotel room may cost more during a busy event, and even an Uber ride may cost more when demand for it increases.

What is interesting here is that a higher price does not necessarily mean that the cost of providing the good or service has changed by the same amount. Sometimes what has changed is the state of the market: more people want the same thing, while its supply remains limited at that moment.

In a market economy, price becomes one of the ways the market reflects this imbalance between demand and supply, and this is where the importance of scarcity becomes clear. This leads to the question: Why do we pay more when demand intensifies?

When Scarcity Becomes Visible in the Price

In economics, prices are determined not only by the cost of producing a good or service, but also by how available it is relative to the level of demand for it.

If demand increases while supply remains limited, scarcity becomes apparent, and price becomes one of the ways the market responds to this imbalance.

This is what we see in Uber's dynamic pricing; when demand exceeds the number of available rides in a particular area, the price may temporarily increase.

The same idea appears in other markets: airline tickets during travel seasons, hotel rooms during events, and limited tickets when interest in them increases.

Here, price reflects not only cost, but also conveys information about the scarcity of the resource at that moment.

When Demand Changes, Price Moves

Demand is not constant. It may increase because of a particular season, an event, or an emergency, while supply needs more time to respond.

When this happens, price becomes a way of dealing with the gap between the two sides. A higher price may lead some consumers to postpone their purchase or look for alternatives, while others continue buying because they believe obtaining the product now is worth paying more for.

Here, one of the fundamental ideas in economics emerges: price affects the quantity demanded; it is not merely a result of it.

Price Reallocates Resources

When a resource is limited, not everyone can obtain it at the same time.

A higher price may exclude some buyers while preserving demand from consumers who are more willing to pay. This means that price does not merely distribute money; it can also help allocate a scarce resource among different uses.

For example, on an Uber ride, one person may prefer to wait until the price drops, while another pays the higher price because they need the ride immediately.

The issue here is not that one person "likes the price" and the other does not; rather, the value of the resource differs from one consumer to another at the same moment.

Producers Also Respond to Price

A high price does not only change buyers' behavior; in many markets, it also represents a greater opportunity for producers and service providers.

When a service becomes more profitable, incentives emerge to provide more of it. In Uber's case, high prices may encourage drivers to head to areas where demand is high.

Thus, the market moves from both sides: some consumers reduce their demand, while some service providers become more willing to supply.

This is the function of incentives in economics: changing prices can change behavior, and behavior in turn helps adjust the market.

Does a Higher Price Mean a Worse Market?

Not necessarily.

It is easy to view a higher price solely from the consumer's perspective: "I will pay more." But broader economic analysis asks another question: What happened to the market as a whole?

A study published in Econometrica in 2025, based on data from the Uber market, found that dynamic pricing increased overall economic welfare by approximately 2.15% of revenue compared with uniform pricing. It also found that consumer surplus increased by approximately 3.57% of revenue.

This finding does not mean that higher prices are always good, but it shows that evaluating pricing efficiency depends not only on the price level itself, but also on its effect on demand, supply, and resource use.

What Determines Our Willingness to Pay?

One person may pay 50 riyals for a service that another person does not consider worth more than 30 riyals.

The difference is not necessarily related to a difference in price, but to a difference in the value of the service to each consumer.

In economics, time is an important factor here. Someone who waits ten minutes to save money incurs another cost: the time that could have been used for work, rest, or any other activity.

This is the opportunity cost; choosing the cheaper option does not always mean it is actually the least costly.

Price as an Economic Signal

That is why the importance of price goes beyond the number displayed on the screen.

When airfares rise during the travel season, hotel prices increase during a major event, or the cost of an Uber ride changes within minutes, we see the market translating a change in demand, supply, or scarcity into a signal understood by both sides.

This signal may not be comfortable for everyone, but it serves an important economic function: guiding consumer and producer decisions when resources are limited and needs are changing.

Therefore, when the price rises because we need something more, the most important economic question is not merely: "Why has it become more expensive?"
but: "What does this price tell us about the market?"
