What Are Reverse Logistics and How Do They Relate to Inventory Management?

The cost of production increases due to increase in prices of capital goods. The Law of Supply and the Law of Demand jointly determine the market equilibrium price and quantity. When supply increases and demand remains constant, prices tend to fall, and vice versa.

Therefore the increase in price gives incentives to producers to produce and offer for sale a large amount of the goods. Thus, the price of the commodity serves as an incentive to produce more and more units of the commodity. Higher the price higher will be an incentive for the producer to produce and supply more. In the above figure, the upward sloping line represents the supply line or supply curve of the firm.

The term premium has several different definitions in finance — Often, it refers to the cost of either a put option or a call option, but can also refer to bond pricing or insurance payments. Consumer income, preferences, and willingness to substitute one product for another are among the most important determinants of demand. As we assumed the different values of ‘P’ from zero to 5, then the calculated values of Qs increases from – 2 to 8. Where c and d are parameters while P and Qs are independent and dependent variables, respectively. The positive sign represents direct relationship between P and Qs.

You’re looking to buy apples, so you go to a supplier and make them your best offer. The more you’re willing to pay for a product, the more of it a seller will be willing to provide. Let’s say you run an oil company and you’ve just discovered a cheaper way to produce oil. Now you can produce more oil for the same cost, and you can sell more oil at the same price.

However, at a relatively lower price, the producers do not release big quantities from their stocks. They start increasing their inventories with a view that price may rise in near future. We know, price is the dominant factor in determining supply of a commodity. As price of the commodity increases, there is more supply of that commodity in the market and vice-versa. This behaviour of producers is studied under the law of supply. A third exception to the law of supply is what’s called the agency problem.

1. A movement along a supply curve occurs when there is a change in the price of a product.
2. The law of supply is also based on the assumption of ceteris paribus i.e., other things remaining the same assumptions.
3. The more you’re willing to pay for a product, the more of it a seller will be willing to provide.
4. The basic aim of producers, while supplying a commodity, is to secure maximum profits.
5. When the price of a product decrease, suppliers have less incentive to produce more units, thus decreasing the supply.

Causes of positive slope of supply curve

The law of supply describes the relationship between price and amount supplied when all other variables remain constant (ceteris paribus). If the number of suppliers increases, or if the capacity of a factory producing the goods increases, the quantity supplied will increase. The law of supply and demand combines two fundamental economic principles that describe how changes in the price of a resource, commodity, or product affect its supply and demand. The supply curve slopes upward because, over time, suppliers can choose how much of their goods to produce and later bring to market.

The Assumption, Reasons and Exceptions to Law of Supply Economics

Price elasticity will also depend on the number of sellers, their aggregate productive capacity, how easily it can be lowered or increased, and the industry’s competitive dynamics. Veblen goods are at the opposite end of the income and wealth spectrum. The substitution effect turns the product into a Giffen good when the price of an inferior good rises and demand goes up because consumers use more of it in place of costlier alternatives. These are typically low-priced staples also known as inferior goods. They’re those who see a drop in demand when incomes rise because consumers trade up for higher-quality products.

Change in Number of Firms:

For this, the firm can sell all the goods by lowering the price which is just the opposite of the law of supply. Based on the above assumption the law of supply can be explained with help the help supply schedule and supply curve. Rare, artistic and precious articles are also outside the scope of law of supply. For example, supply of rare articles like painting of Mona Lisa cannot be increased, even if their prices are increased.

1. The above table shows the positive relationship between the price of the commodity and quaintly supply by the seller.
2. So, producers increase the supply of the commodity by increasing the production.
3. For this, the firm can sell all the goods by lowering the price which is just the opposite of the law of supply.
4. With a rise in price, the tendency is to increase supply because there is now more profit to be earned.
5. Let’s say you need to produce 1M bottles of cider, so you build a bottling factory.
6. Those next options will cost more — Since the cheaper option was already likely used.

Discover the significance of elasticity in economics and its impact on pricing, taxation, and inventory management strategies. In case of perishable goods, like vegetables, fruits, etc., sellers assumptions of law of supply will be ready to sell more even if the prices are falling. Let’s say you need to produce 1M bottles of cider, so you build a bottling factory. Now let’s say that by running those machines longer, the same factory can produce 2M bottles of cider.

As mentioned earlier, the supply curve is upward sloping, indicating that as the price of a product increases, the quantity supplied also increases. In the case of the auction sale, the law of supply is not applicable. An action sale may occur at the situation when the seller is in a financial crisis and needs money at any cost.

The laws of supply and demand were first described in philosophy. Adam Smith formalized the discipline of economics in 1776, with the book The Wealth of Nations. Products with a high price elasticity of demand will see wider fluctuations in demand based on the price. Basic necessities will be relatively inelastic in price because people can’t easily do without them so demand will change less relative to changes in the price. In plain terms, this law means that as the price of an item goes up, suppliers will attempt to maximize their profits by increasing the number of that item that they sell. The amount of investment is affected by the change in political situation of a country.
