Yes, Price effect = substitution effect + income effect
chnage in consumer's equilbrium due to change in income of the consumer..known as income effect.
substitution diminishing marginual utility income
Proof that all Giffen goods are inferior goods but not all inferior goods are Giffen goods. A Giffen good is defined as dx/dp > 0 (i.e. quantity demanded increases with own-price). An inferior good is defined as dx/dm < 0 (i.e. quantity demanded decreases with income). The own-price Slutsky equation tells that: dx/dp = dh/dp - x(dx/dm) (own-price elasticity of demand = substitution effect - income effect), where h is the Hicksian demand. dh/dp is always negative. If the good is Giffen, then the left hand side of the Slutsky equation is positive. Since dh/dp is negative, then it must be the case that dx/dm is negative (i.e. the good is inferior), since otherwise a positive income effect subtracted from the substitution effect would give a negative result. Therefore, all Giffen goods are inferior goods. Yet, it may be the case that x(dx/dm) is negative, an inferior good, but that the income effect is lesser than the substitution effect, so that the left hand side of the equation remains negative. Thus, not all inferior goods are Giffen.

substitution effect and income effect :) 100% accurate
Price effect in quantitative term, is the changed in quantity demanded of a good due to changes in its price,ceteris paribus. The price effect, however, is a net effect of two sub-effects: Income effect and substutuion effect. Thus, decomposition of price effect means the analysis by which the the price effect is into its two components viz. substitution effect and income effect
substitution effect is the explanation for the downward slope of the aggregate damnd curve.
decompose total effect of price increase for an inferior good and giffen into substitution and income effect, in each case derive both the ordinary and compensated demand curve

The Income Effect is the effect due to the change in real income. For example, when the price goes up the consumer is not able to buy as many bundles that she could purchase before. This means that in real terms she has become worse off. The Substitution Effect is the effect due only to the relative price change, controlling for the change in real income. In other words, the substitution effect is the change in consumption patterns due to a change in the relative prices of goods. For example: Let's say you are a Pizza shop owner, and the price of Italian Cheddar cheese goes up. You would have to substitute American cheddar cheese (which costs less but is not as good as Italian cheddar cheese) So the substitution effect is when you have to substitute a good or product for something that costs less when you have a low amount of money or when the price goes up.
