What is adam smith`s law of supply and demand
When technological progress occurs, the supply curve shifts. For example, let`s say someone invents a better way to grow wheat so that the cost of growing a certain amount of wheat goes down. Otherwise, producers will be willing to supply more wheat at any price, which shifts the supply curve from S1 outward to S2 – an increase in supply. This increase in supply causes the equilibrium price to fall from P1 to P2. The equilibrium quantity increases from Q1 to Q2 as consumers move along the demand curve to the new lower price. Due to a shift in the supply curve, prices and quantities move in opposite directions. If the quantity delivered decreases, the opposite happens. If the supply curve starts at S2 and moves to the left to S1, the equilibrium price rises and the equilibrium quantity decreases as consumers move along the demand curve to the new, higher price and associated lower amount of demand. The quantity demanded at each price is the same as before supply shifted, reflecting the fact that the demand curve has not moved. But due to the change (shift) in supply, the equilibrium quantity and price have changed. Supply and demand theory refers not only to physical products such as televisions and jackets, but also to wages and the movement of labor. More advanced theories of microeconomics and macroeconomics often adjust the assumptions and appearance of the supply and demand curve to properly illustrate concepts such as economic surplus, monetary policy, externalities, aggregate supply, fiscal stimulus, elasticity, and deficits. Before considering these more complex issues, it is necessary to understand the fundamentals of supply and demand.
Much of the buying and selling is now done online through platforms such as Amazon and eBay, where customer profiles are collected and analyzed. Tshilidzi Marwala and Evan Hurwitz noted in their book  that the advent of artificial intelligence and related technologies such as flexible manufacturing offers the opportunity to generate individualized demand and supply curves. This has reduced the degree of arbitrage in the market, allowed individualised pricing for the same product and improved market efficiency. If demand decreases, the opposite happens: a shift of the curve to the left. If demand starts at D2 and falls to D1, the equilibrium price decreases and the equilibrium quantity also decreases. The quantity delivered at each price is the same as before the demand shift, reflecting the fact that the supply curve has not moved. But the quantity and the equilibrium price are different because of the change (change) in demand. The basic idea behind the law of supply and demand is that at some point, a price “too high” leaves potential sellers disappointed with unsold products, while a price “too low” leaves potential buyers disappointed without the goods they want to buy. There is a “good” price at which anyone who wants to buy can find sellers who are willing to sell, and anyone who wants to sell can find buyers who are willing to buy. This “fair” price is therefore often referred to as the “market clearance price”. The most fundamental laws in economics are the law of supply and the law of demand. In fact, almost all economic events or phenomena are the product of the interaction of these two laws.
The Credits Act states that the quantity of a product supplied (i.e., the quantity that owners or producers offer for sale) increases when the market price rises and decreases when the price falls. Conversely, the law of demand (see demand) states that the quantity of a good demanded decreases with the increase in price and vice versa. (Economists don`t really have a “law” of supply, although they speak and write as if they were talking about it.) The law of supply and demand is actually an economic theory popularized by Adam Smith in 1776. The principles of supply and demand have proven to be very effective in predicting market behaviour. However, several other factors influence markets at the micro and macroeconomic levels. Supply and demand strongly determine market behavior, but do not directly determine it. After Smith`s publication in 1776, the field of economics developed rapidly and the law of supply and demand was refined. In 1890, Alfred Marshall`s Principles of Economics developed a supply and demand curve that is still used to show the point at which the market is in equilibrium. Economic theory, in its simplest embodiment of supply and demand, makes a number of strong predictions. Consider a chart (see Figure 1) that shows the price on the vertical axis and the quantity on the horizontal axis. The delivery schedule answers the question: how many units would voluntarily be put on the market at different prices? Therefore, the offer in this experimental structure is a model of ascending stair steps that starts at $10 and increases by $2 per step for each unit on the market. Above $18, the supply curve is vertical, as only five units can be purchased in this context.
Similarly, the demand plan answers the question: how many units are voluntarily purchased on the market at different prices? Using the same analysis as the sellers, we find that the demand plan is a pattern of descending stair steps that starts at $22 and decreases by $2 per step for each unit demanded in the market. Below a price of $14, the demand plan is also vertical, as no more than five units are desired in this framework. For this scenario, the textbook economy predicts that equilibrium will be reached where supply matches demand. In this case, it means that four units are trading at the same price of $16. Economists often talk about “demand curves” and “supply curves.” A demand curve follows the quantity of a good that consumers will buy at different prices.
