The notion of demand refers to a request, request, appeal or request . The one who demands requests that something be delivered. For example: "The kidnapper demands a million pesos to free the hostages", "The demand for dairy products has grown in recent years", “The government demands a greater effort of the companies to avoid the advance of the unemployment”.
In the field of right , the claim is the petition that the litigant makes and justifies during a trial. It is also the letter in which the actions are brought before the court or the judge: "The European Union filed a lawsuit against Microsoft for monopolistic activities", "The actor threatened to initiate a lawsuit for those who publish photos of his son".
The plaintiff (the one who files the lawsuit) must comply with different types of responsibility. The procedural responsibility it demands the payment of the costs of the trial (the plaintiff must pay if his claim is rejected due to lack of foundation), while the civil liability It is specified with the payment of compensation to the defendant (when the claim is unfounded or includes an injurious charge). Finally, the criminal liability it implies a criminal sanction and appears when the defendant commits a crime during the judicial process (such as the presentation of false documents).
The demand in the economy
For the economy , demand is the sum of purchases of goods and services that a certain social group makes at a given time. You can talk about individual demand (when it involves a consumer) or total demand (with the participation of all consumers of a market ).
In this market the quantity of the product that is demanded can vary , depending on several factors, fundamentally its price, its availability and the wealth and need of those who wish to acquire it.
Price is one of the determining factors of a product and is of variable type; This means that it can be modified over time, usually in cases where it is necessary from the eyes of the offeror.
If a product has a great outlet in the market, the decline in its stocks makes it more precious and, to get a better profit, the producers increase their price; On the other hand, if it is a product that has not had a great impact, its price is usually lowered to successfully place it in the market.
The latter occurs mainly in food goods, with an expiration date, in order not to lose everything invested in the manufacture or collection of the product, producers prefer to sell it before the expiration date at an even lower price than the expenses involved in getting it.
The demand curve It allows to know the relationship between the quantity demanded of a product and its price. That is, the quantities that consumers would like to acquire from a product based on a price and in a certain time.
It should be mentioned that, together with the supply curve, the demand curve is one of the tools used in the economic field to theoretically analyze the different market states and predict its future in order to establish future prices that favor the fluid exchange of goods and services . The space in which both curves intersect is known as equilibrium. It is a point of intersection where both are on equal terms.
We can also say that demand is a mathematical function through which you can know the availability and existence of a product in the market and the interest therein on the part of the consumers. This merger is made up of several parts, where each acronym represents a certain part. Qdp (represents the quantity demanded), P (is the price of good), I (refers to consumer income), G (reflects tastes and preferences), N (number of interested consumers), Ps (represents the prices of substitute goods) and PC (the price of complementary goods).
