HyperInflation(exceeding monthly 50%), Inflation, Disinflation (Decreasing Inflation Rate), Deflation (Long-term negative inflation)
CPI : Purchasing Pattern of a typical household
GDP deflator : Convert Nominal GDP into Real GDP
ex) GDP deflator = 120, Nominal GDP = 250, Real GDP = 250/1.2=210
Laspeyres = P1*Q0 / P0*Q0
Passhce = P1*Q1 / P0*Q1
Fisher(Chined or Chain weighted Index) = Geometric mean of Laspeyres * Passhce
Hedonic pricing = consider product quality; reducing substitution bias
PPI(Producer) : to Watch cost pressure by observing each production stage (raw materials, intermediate goods, and finished goods)
WPI(Wholesale)
Headline Inflation : Everything included
Core Inflation : Exclude Food and Energy which is more volatile
