What is difference between slope and the calculation of elasticity for a linear demand curve?

Along a linear demand curve elasticity varies from point to point of the demand curve with respect to different price, but slope is constant


Is the price elasticity constant along the demand curve?

Price elasticity of demand is equal to the instantaneous slope of the demand curve, or the slope of the tangent line at any point on the demand curve. So if the demand curve is represented by a straight downward sloping line, then yes, price elasticity of demand is equal to the slope of the demand curve. Otherwise, the slope at any point on the curve is changing, and you can find the it by taking the derivative of the demand curve function, which will find the Price elasticity of demand at any single point. Thus, the Price Elasticity of Demand changes at different points on the demand curve.

What is the difference between the price elasticity of demand along a demand curve and the rate of change along the demand curve?

The price elasticity of demand measures how responsive the quantity demanded is to changes in price, expressed as a percentage change in quantity divided by a percentage change in price. It varies along a demand curve depending on the price level and quantity, indicating whether demand is elastic or inelastic at specific points. In contrast, the rate of change along the demand curve refers to the absolute change in quantity demanded in response to a change in price, without considering percentage changes. Essentially, elasticity is a relative measure, while the rate of change is an absolute measure.


How does elasticity vary along a straight-line demand curve?

Elasticity varies along a straight-line demand curve by being different at different points. At the top of the curve, elasticity is more elastic, meaning small changes in price lead to larger changes in quantity demanded. At the bottom of the curve, elasticity is less elastic, meaning changes in price have less impact on quantity demanded.

What is the relation between slope of demand curve and elasticity of demand curve?

They are both used to interpret the demand curve. The slope is just the slope, rise or run, ΔY/ΔX. Elasticity is the percentage change in one variable resulting from a percentage change in another variable. Thus, the price elasticity of demand is the percentage change in quantity demanded of a good resulting from a percent change in its price. (P/Q)( ΔQ/ ΔP) This implies that the elasticity is not constant and the elasticity changes along the curve; elasticity goes from 0 (when price is 0) to infinity (when price is very high). Elasticity is a more useful tool for data analysis because it eliminates units and thus the data is easier to interpret. Elasticity is also useful when large numbers are an obstacle in interpreting data like with wage. It is also useful when the taking the log with a set of data preserves the integrity of the data, since elasticity is the slope of the log of the data points.


What motion is a type of motion that exists in curves and circles?

Circular motion is a type of motion that exists in curves and circles. In circular motion, an object moves along a circular path at a constant speed. The velocity of the object is constantly changing in direction, but the speed remains constant.


Why does PED change along the demand curve (in economics)?

Price Elasticity of Demand (PED) changes along the demand curve due to the inverse relationship between price and quantity demanded. As the price decreases, consumers may become more sensitive to price changes, resulting in higher elasticity. Conversely, at higher prices, consumers may be less responsive to price changes, leading to lower elasticity. This variation occurs because the proportion of income spent and the availability of substitutes can influence consumer behavior at different price levels.


Is income held constant along the demand curve?

Yes, an increase or decrease in income will cause a shift in the demand curve right or left depending on if the good is inferior, normal, or superior


Why does unitary elastic demand curve is a rectangular hyperbola?

we know from total expenditure method of measuring elasticity of demand that if total expenditure remains the same when price changes, elasticity is unitary. rectangular hyperbola is a curve under which all rectangular areas are equal. also, each rectangular area shows total expenditure on the commodity. along the curve, even if price changes, total expenditure remains the same, so rectangular hyperbola shows the elasticity of 1.
