How does economics understand just need?

Demand curve The demand curve shows the quantity of goods required at each price. Demand curve is a curve showing the relationship between price and demand, which refers to the table or curve of the quantity of goods that buyers are willing to buy at various price levels under the same other conditions. Where demand cannot be observed. The demand curve can appear in any shape, and the demand curve that can conform to the demand theorem can only tilt to the lower right.

demand curve

The slope of the demand curve indicates the price elasticity of demand. Numerically, the price elasticity coefficient = 1/ curve slope. Because the slope of the curve is negative, the smaller the slope (the curve is gentle), the greater the price elasticity coefficient, and the higher the price elasticity of the commodity. Every unit price change will bring a lot of demand, but the slope of demand currency is not static, and the slope of demand curve of most commodities is gradually reduced, and the demand curve will gradually become smooth.

The rigid demand curve is theoretically a straight line, that is, it is not affected by price changes. For example, salt is not only a necessity, but also irreplaceable. From this perspective, buying a house is not a rigid demand, but housing is a rigid demand, and housing may be realized in many ways, such as leasing.

Developers often emphasize the rigid demand for housing, and making a fuss about housing prices is one of the means to mislead consumers.

People's willingness to buy a house is constantly changing with the price level. When the house price is too high for consumers to afford, only a few people can afford it, so naturally fewer people buy a house. On the contrary, when housing prices are at a low level, people with housing needs and investment needs are willing to buy a house. Therefore, the demand for commercial housing is flexible.

Sustained release

2012 1 February 21,the state information center said that the current policy is still unable to effectively force out the stock of housing, the supply of the real estate market is still insufficient, and the reasonable return of housing prices has been a long time.

Zhu Baoliang, director of the forecasting department of the National Information Center, explained that if the current control policy is maintained, the rigid demand for real estate will be released, which will push up housing prices, but the probability of a big increase is not great.

If the property tax is implemented, it will lead to an increase in the supply of second-hand houses, which may lead to a decline in house prices.

Zhu Baoliang believes that this round of regulation and control policy mainly focuses on restricting purchases and loans, and does not involve the taxation of property ownership. Regulation only has an impact on new investment and speculative demand. For real estate owners who hold multiple houses before the regulation, the cost of holding houses has not changed significantly.

In the market game, the house price has not been greatly reduced, but the rent has increased, so the holders of multiple houses are not in a hurry to sell, and the reasonable return of house prices has become even longer.
